Water Heater Acting Up? Here’s What Each Symptom Actually Means

Few problems in a home get noticed as quickly as something going wrong with the water heater. The harder part is figuring out which of several possible causes is actually responsible, since a handful of very different problems can produce symptoms that look similar at first.

Quick Answer: The fastest way to narrow down a water heater problem is to start with the specific symptom rather than guessing at a cause. No hot water at all usually points to a pilot light or thermocouple issue on gas units, or a heating element or breaker on electric units. Hot water that runs out quickly often means sediment buildup or a tank that is undersized for household demand. Rust-colored water points to a depleted anode rod. Popping or rumbling noise almost always traces back to sediment as well.

Start With the Symptom, Not the Guess

Diagnosing a water heater problem accurately starts with identifying the specific symptom, since different symptoms point to different components and different fixes.

It is tempting to assume the tank is simply getting old and needs to be replaced, but several distinct problems can affect a water heater, and each one has its own specific cause and its own specific fix. Troubleshooting a hot water heater effectively starts by matching what is actually happening, no hot water, weak supply, discolored water, or an unusual sound, to the component most likely responsible, rather than assuming the whole unit is at fault.

No Hot Water at All

A complete loss of hot water usually points to a failed ignition or heating component rather than the tank itself, and the likely cause depends heavily on whether the unit is gas or electric.

Gas Units: Pilot Light and Thermocouple

On a gas water heater, a pilot light that has gone out or a faulty thermocouple are the two most common reasons for a complete loss of hot water. The thermocouple is a safety sensor that detects whether the pilot flame is lit and shuts off the gas supply if it is not, so a failing thermocouple can prevent the burner from staying lit even when the pilot itself is fine.

Electric Units: Heating Element and Breaker

On an electric water heater, a burned-out heating element is the most common cause of a total loss of hot water, though a tripped breaker is worth checking first since it produces the exact same symptom and takes only a moment to rule out. Electric units typically have two heating elements, an upper and a lower, so a partial loss of hot water rather than a complete one can point specifically to one element failing while the other still works.

Hot Water Runs Out Quickly

Hot water that runs out faster than it used to points to either sediment buildup reducing the tank’s effective capacity or a tank that was undersized for the household’s demand from the start.

Sediment settles at the bottom of the tank over years of use and physically displaces water, which means less usable hot water is available even though the tank’s rated capacity has not changed. A tank that has always struggled to keep up during heavy use, multiple showers back to back, or a shower running at the same time as a dishwasher, is more likely dealing with a capacity mismatch than a new mechanical problem.

Rust-Colored Water

Rust-colored hot water points to a depleted anode rod, which allows the inside of the tank itself to begin corroding.

The anode rod is a sacrificial piece of metal designed to corrode before the tank does, protecting the tank’s interior from rust for as long as the rod lasts. Once the rod is fully depleted, the tank’s steel lining is exposed to the same corrosive process, and the tank itself begins to rust from the inside. At that point, replacement of the tank is typically the only viable option, since a rusting tank cannot be repaired the way an anode rod can be replaced.

Popping or Rumbling Noise

A popping or rumbling sound from a water heater is almost always caused by sediment buildup trapping small pockets of water beneath it that turn to steam as the burner heats the tank.

The sound itself comes from those steam pockets forcing their way up through the sediment layer. This is the same underlying cause behind the reduced-capacity symptom described above, since the sediment producing the noise is also the sediment displacing usable water in the tank. For a closer look at exactly why this sound happens and what it means for the tank long-term, see Why Is My Water Heater Making a Popping or Rumbling Noise?.

What an Experienced Technician Checks First

An experienced technician typically asks about the specific symptom before touching the unit, since the answer narrows the likely cause down to one or two components before any diagnostic tools come out.

ā€œThe first question is always what exactly is happening, not just that something is wrong. No hot water at all on a gas unit sends me straight to the pilot and thermocouple. The same symptom on an electric unit sends me to the breaker panel first, then the elements. Rust in the water means I am already thinking about the anode rod before I even look at the tank.ā€

Adam Rhodes, Expert Plumbing Technician

Flush, Repair, or Replace: Making the Right Call

Whether a water heater problem calls for a simple flush, a targeted repair, or full replacement depends on which component has failed and how far along the underlying wear has progressed.

A tank flushed once a year before sediment has a chance to accumulate heavily is a straightforward maintenance step that can prevent several of the symptoms described above from developing in the first place. A failed thermocouple, heating element, or thermostat is typically a component-level repair rather than a reason to replace the whole unit. A depleted anode rod caught early can sometimes still be replaced on its own, but once the tank itself has started to rust, or once sediment buildup is severe enough that flushing no longer restores capacity, replacement becomes the more practical option. For a closer look at how to weigh that specific decision, see Is It Time to Replace My Water Heater?.

People Also Ask: Water Heater Problems

What is the most common reason a water heater stops producing hot water?

A complete loss of hot water is most often caused by a failed pilot light or thermocouple on a gas unit, or a burned-out heating element or tripped breaker on an electric unit. Checking the breaker first takes only a moment and rules out the simplest possible cause before assuming a component has failed.

Why does a water heater make a popping or rumbling sound?

Popping or rumbling almost always comes from sediment that has settled at the bottom of the tank. Small pockets of water get trapped beneath that sediment layer, and as the burner heats the tank, those pockets turn to steam and force their way up through the buildup, producing the sound.

Can sediment buildup really reduce how much hot water is available?

Yes. Sediment settles at the bottom of the tank and physically takes up space that would otherwise hold water, which reduces the tank’s usable capacity even though its rated size has not changed. A tank that used to provide enough hot water for a full shower and now runs out early is a common sign of this.

What does rust-colored hot water usually mean?

Rust-colored hot water typically means the anode rod, a sacrificial piece of metal designed to corrode in place of the tank, has been fully depleted. Once that happens, the tank’s own lining is exposed to the same corrosive process and can begin to rust from the inside.

How often should a water heater tank be flushed?

Flushing a tank once a year is a common recommendation for preventing sediment from accumulating to the point where it causes noise, reduced capacity, or efficiency problems. A tank that has already gone several years without a flush may have sediment buildup significant enough that flushing alone no longer fully restores performance.

Is a water heater problem usually a simple repair or a full replacement?

It depends entirely on which component is affected. A failed thermocouple, heating element, or thermostat is typically a straightforward repair, while a tank that has started to rust from the inside, usually after the anode rod has been depleted for some time, generally calls for replacement rather than repair.

Can a gas and an electric water heater have the same symptom but different causes?

Yes, and this is one of the more common sources of confusion. A complete loss of hot water looks identical on the surface for both types, but a gas unit points toward the pilot light or thermocouple, while an electric unit points toward the breaker or a heating element. Knowing which type of unit is installed is the first step in narrowing down the cause.

Does a water heater need to be replaced just because it is making noise?

Not necessarily. Popping or rumbling noise on its own usually points to sediment buildup, which can often be addressed with a tank flush rather than a full replacement. Noise combined with other signs, such as rust-colored water or a tank that is already well past its typical service life, is a stronger signal that replacement is the more practical option.

Can a tripped breaker be mistaken for a failed electric water heater?

Yes. A tripped breaker cuts power to the entire unit and produces the same complete loss of hot water that a failed heating element would cause. Checking the breaker panel before assuming the unit itself has failed is a simple step that can rule out the least expensive possible cause first.

How can a homeowner tell whether a water heater problem needs a repair visit or an emergency call?

A slow decline in performance, longer wait times for hot water, reduced supply, or an occasional odd noise, generally allows time to schedule a standard repair visit. Active leaking, a tank showing signs of failure, or a complete loss of hot water in a household that depends on it immediately are better handled as an emergency plumbing call.

What Incentives Exist for Home EV Charger Installation in North Carolina?

Owning an electric vehicle makes a Level 2 charger at home worth having, but the cost of installing one has shifted more in the past year than it has in the previous several years combined. Incentive programs that applied even a few months ago do not all still apply today, and getting the current picture right matters more than usual right now.

Quick Answer: As of July 31, 2026, North Carolina does not have a statewide tax credit for home EV chargers. The federal Alternative Fuel Vehicle Refueling Property Credit, which covered 30 percent of hardware and installation costs up to $1,000 per charging port, expired on June 30, 2026, and is no longer available for equipment placed in service after that date. Duke Energy’s Charger Prep Credit remains active for North Carolina customers, providing up to $1,133 toward the electrical upgrades needed to prepare a home for a Level 2 charger, though it does not cover the cost of the charger itself.

Exploring North Carolina EV Charger Incentives

North Carolina does not currently offer a statewide rebate for EV charging station installation, and that applies to Tesla charging equipment and every other brand of charger equally. With that said, homeowners in the Greensboro area can still reduce the cost of a charger through a Duke Energy rebate, and could until recently combine that with a federal tax credit as well. That federal option has now closed, which makes it worth understanding exactly what changed and what is still on the table.

The Federal Tax Credit Has Expired

The federal Alternative Fuel Vehicle Refueling Property Credit expired on June 30, 2026, and no longer applies to home charging equipment placed in service after that date.

For years, this credit covered 30 percent of the cost of a home charger and its installation, up to $1,000 per charging port, for equipment placed in service between January 1, 2023 and its original scheduled expiration at the end of 2032. The One Big Beautiful Bill Act, signed in 2025, moved that expiration date up significantly, ending the credit for individual homeowners as of June 30, 2026 rather than 2032. Anyone who had a charger installed and placed in service on or before that date can still claim the credit on the applicable tax return, but installations completed after June 30, 2026 no longer qualify under this program.

What ‘Placed in Service’ Means and Why the Date Matters

The credit’s deadline is based on when the charger was ready to use, not when it was purchased or when installation began, which means the exact completion date of a project determines eligibility.

Equipment that was installed and functional by June 30, 2026 generally still qualifies, even if the invoice was paid slightly earlier or later, since the standard applied is whether the equipment was ready for use by the deadline. A project that was only partially complete, or scheduled but not yet installed, by that date does not qualify. Anyone unsure whether a specific project falls on the right side of that line should confirm the details with a tax professional rather than assume either way.

Duke Energy’s Charger Prep Credit

Duke Energy’s Charger Prep Credit remains active for North Carolina customers and provides up to $1,133 per household toward the electrical upgrades needed to prepare a home for a Level 2 charger.

This credit is specifically for the electrical infrastructure work required to get a home ready for a charger, wiring, conduit, outlet installation, and panel upgrades, rather than for the cost of the charger hardware itself. Duke Energy offers two ways to receive it. A customer can hire an electrician independently, pay for the work, and submit the paid invoice for reimbursement, or a customer can work with a Duke Energy-approved contractor and have the credit applied directly to the final bill. Customers who already had the prep work completed may still be eligible if the invoice or approved permit falls within Duke Energy’s recent completion window, so it is worth checking even for work that has already been done.

This is exactly the kind of electrical prep work that determines whether a home’s existing panel can support a Level 2 charger in the first place. For a closer look at how that assessment works, see Will Your Home’s Electrical System Support EV Charger Installation?.

What an Experienced Electrician Checks Before Filing for the Credit

An experienced electrician typically confirms the scope of qualifying work and documents it in a way that matches the utility’s requirements before any application is submitted, since paperwork gaps are a common reason rebate requests get delayed.

ā€œThe rebate covers the prep work, not the charger itself, and that distinction trips people up more than anything else. Before I start a job, I walk through exactly which parts of the work qualify, the panel upgrade, the new circuit, the outlet, and make sure the invoice breaks those out clearly. A vague invoice is the most common reason a straightforward rebate request gets kicked back for more information.ā€

Toni Mortera, Expert Electrician

Working With a Tax Professional on Any Remaining Credits

Confirming eligibility with a tax professional before counting on any credit is the safest way to avoid planning around a benefit that does not apply to a specific tax situation.

Tax credits depend on details that vary from household to household, including overall tax liability, filing status, and exactly when a piece of equipment was placed in service. A tax professional can confirm whether a specific installation falls before or after the federal credit’s expiration, whether any state or local program applies, and how to document the purchase and installation costs correctly on the applicable form. Assuming eligibility without that confirmation, only to find out later that a credit does not apply, is a frustrating and avoidable outcome.

Is a Home EV Charger Still Worth It Without the Federal Credit?

A home EV charger remains a worthwhile investment even without the federal tax credit, since the convenience of overnight charging and the appeal to future buyers do not depend on any specific incentive program.

The math has changed with the federal credit gone, but it has not disappeared. Duke Energy’s Charger Prep Credit still meaningfully offsets the electrical work most homes need before a Level 2 charger can be installed safely, and that is often the more expensive part of the project relative to the charger hardware itself. Beyond any specific incentive, a home charger removes the daily friction of public charging and is increasingly something buyers expect to see in a home with a garage or driveway, regardless of what tax credits happen to be available in a given year.

Why Incentive Programs Change So Often

Incentive programs shift because they are tied to specific funding sources and legislative or regulatory approval windows, not because the underlying value of home EV charging has changed.

Federal tax credits like the one that expired this year are created and modified through legislation, which means a change in federal budget priorities can move an expiration date up by years with very little notice, exactly what happened here. Utility programs like Duke Energy’s Charger Prep Credit work differently. They are typically approved by a state utility commission, funded through a specific budget allocation, and designed to run until that funding is used or the program is renewed. That structure means a utility rebate can remain stable for years or can be adjusted with a new commission filing, and it is a separate process entirely from anything happening at the federal level. Understanding this distinction is useful context: a change to one program does not necessarily signal anything about the other, and homeowners who assume otherwise sometimes miss out on incentives that are still fully available. Any electrical repair or panel upgrade work planned as part of an EV charger project is worth timing around whichever program’s current rules actually apply, rather than assuming last year’s rules still hold.

Work with Berico on This Project

Regardless of which incentives currently apply, installing an EV charging station installation remains a valuable addition to a home that improves daily convenience and appeals to future buyers. Whether the project involves a new charger, Tesla charging equipment specifically, or electrical repair to prepare an existing panel, a call to the team at Berico is where the project starts.

People Also Ask: EV Charger Incentives in North Carolina

Has the federal EV charger tax credit expired?

Yes. The federal Alternative Fuel Vehicle Refueling Property Credit expired on June 30, 2026, under the One Big Beautiful Bill Act, which moved up its original 2032 expiration date. Equipment placed in service on or before June 30, 2026 can still qualify, but installations completed after that date no longer qualify under this specific program.

What incentives are still available for a home EV charger in North Carolina?

North Carolina does not have a statewide tax credit for home EV chargers, but Duke Energy’s Charger Prep Credit remains active for North Carolina customers, providing up to $1,133 per household toward the electrical upgrades needed to prepare a home for a Level 2 charger. This credit does not cover the cost of the charger itself.

Does the Duke Energy rebate cover the cost of the charger?

No. Duke Energy’s Charger Prep Credit is specifically for the electrical infrastructure work required to prepare a home for a charger, such as wiring, panel upgrades, conduit, and outlet installation. The charger hardware itself is not covered under this program.

How do homeowners apply for Duke Energy’s Charger Prep Credit?

Duke Energy offers two paths. A customer can hire an electrician independently, pay for the qualifying work, and submit the paid invoice for reimbursement, or work with a Duke Energy-approved contractor who applies the credit directly to the final bill. Customers who already completed the work recently may still be eligible if the invoice or permit falls within Duke Energy’s completion window.

What happens if a charger was installed before the federal credit expired?

Equipment placed in service on or before June 30, 2026 generally still qualifies for the federal credit, even if some paperwork is finalized slightly afterward, since eligibility is based on when the equipment was ready for use rather than when it was purchased. A tax professional can confirm how a specific project’s timeline applies.

Can multiple EV charger incentives be combined?

Combining the Duke Energy Charger Prep Credit with the federal tax credit was possible for projects completed before June 30, 2026. With the federal credit now expired, the Duke Energy program remains the primary NC-specific incentive available, and there is no indication it needs to be used alone rather than alongside other unrelated programs a household may qualify for.

Is installing a home EV charger still worth it without the federal tax credit?

Yes, for most homeowners. The federal credit was a meaningful discount, but the core benefits of a home charger, overnight charging convenience and appeal to future buyers, do not depend on that specific program. Duke Energy’s rebate still offsets a real share of the typical project cost, particularly the electrical prep work.

Do all North Carolina utilities offer an EV charger rebate?

No. Rebate availability depends on which utility serves a specific home. Duke Energy’s Charger Prep Credit applies to Duke Energy Carolinas and Duke Energy Progress customers, and other utilities and electric cooperatives across the state may or may not offer a comparable program. Checking the specific utility listed on a home’s electric bill is the first step.

Should a homeowner consult a tax professional before counting on an EV charger credit?

Yes. Tax credit eligibility depends on details specific to each household, including overall tax liability and the exact date equipment was placed in service. A tax professional can confirm whether a specific project qualifies for any remaining credit and how to document it correctly, rather than assuming eligibility and finding out otherwise when filing.

Does an electrical panel need to be upgraded before installing a Level 2 charger?

It depends on the home’s existing electrical capacity. A load calculation determines whether the current panel can safely support a Level 2 charger alongside existing appliances, or whether a panel upgrade is needed first. This is exactly the kind of work Duke Energy’s Charger Prep Credit is designed to help offset.

Is It Bad to Have an AC Unit in the Attic in Eden, NC?

An air conditioner in the attic raises real questions about heat, efficiency, and long-term reliability for a home in the Eden area. This guide breaks down what actually happens to an AC unit that lives in an Eden attic, where the real risks are, and what protects the investment long term.

Quick Answer: An air conditioner in the attic is not inherently bad, and it is a common setup in Eden-area homes. The bigger concerns are extreme attic heat, added strain on equipment lifespan, and the risk of condensate leaks. With proper insulation, a secondary drain pan, and regular maintenance, an attic-installed system can perform reliably for years.

The Truth About AC in the Attic

There is nothing inherently wrong with an attic air conditioner installation in an Eden-area home, but the location adds heat and moisture challenges that a basement or closet installation would not face.

It is a common setup in the Eden area, and the attic can be a perfectly fine place for the unit to live for many years. Homeowners should understand the efficiency and reliability challenges that come with the arrangement, though. An Eden attic gets extremely hot during the summer months, which forces the unit to work harder every time it runs, and that added strain can shorten the system’s expected lifespan over time.

Why Attic Heat Is the Biggest Problem

The single biggest problem with an air conditioner installed in the attic in Eden, or anywhere else in North Carolina, is heat, since attic temperatures during peak summer can climb past 130°F and force the system to fight its own environment.

During the hottest parts of summer, the temperature in an Eden attic can easily reach 130°F or higher. While the AC unit runs, it pulls warm air in from the house, cools it, and sends it back out through the ducts. When that process happens inside a space that is already extremely hot, the system fights the environment on every single cycle. That means longer run times, harder-working components, and less comfort delivered for the energy spent.

Experienced technicians usually check attic insulation and duct sealing before they touch the refrigerant charge, because a duct run that has lost its insulation or developed a small tear will let cooled air bleed heat back into the airstream before it ever reaches a bedroom or living room. Weak airflow that looks like a refrigerant problem can actually be a duct insulation problem in the attic, and replacing parts without addressing the duct insulation usually means the same complaint returns within a season.

How Attic Heat Shortens Equipment Lifespan

Constant exposure to attic heat accelerates wear on an air conditioner’s air handler and electronic components, and it commonly cuts years off the system’s expected service life.

Higher energy bills from cooling an Eden home all summer are concerning enough on their own, but the bigger cost often shows up later. Attic air conditioner installation almost always means dealing with an environment the equipment was not originally designed for. An air conditioner forced to run in a hot attic experiences premature wear on its components, particularly the air handler and its electronics. Circuit boards and capacitors are generally built for a narrower temperature range than the mechanical parts around them, and prolonged exposure above that range is one of the more common reasons attic-installed systems fail earlier than units placed in a basement or a conditioned closet. Given the price of a new system, losing even a few years of service life is a real financial hit.

The Risk of Attic AC Leaks

An attic-installed AC unit carries a real risk of water damage, since a condensate leak in the attic drains by gravity straight down into the ceiling and walls below before anyone notices.

AC units produce condensate as they run, and while that water is supposed to be routed outside, leaks are always possible. If an air conditioner leaks in the attic, the water follows gravity directly down into the home, and it can cause significant damage along the way, often before a ceiling stain gives the problem away. At minimum, any attic-installed air conditioner should have a secondary drain pan and a float switch that shuts the system down automatically if the primary drain line becomes clogged.

The secondary drain pan sits out of sight, so it is easy for a problem there to go unnoticed until something has already gone wrong. A standalone water leak sensor placed near the unit adds an extra layer of protection, since it can flag a slow drip long before the damage reaches the ceiling. A pan that is rusted, cracked, or already holding standing water is a sign that a repair is overdue, not something to monitor for another season.

What an Experienced HVAC Technician Looks For

An experienced technician typically inspects the secondary drain pan, float switch, and duct insulation before evaluating anything else on an attic-installed system, since those three components explain most of the problems homeowners report.

ā€œThe first thing I check on any attic system is the secondary drain pan and the float switch, because that’s the one component standing between a clogged line and a ruined ceiling. On older attic installs around Eden, I also check the duct insulation before I touch the refrigerant charge, since a poorly insulated duct run can look like a low-refrigerant problem and lead a homeowner to pay for the wrong repair.ā€

Signs an Attic AC Unit Needs Attention

Musty odors, ceiling stains, longer cooling cycles, and unexplained jumps in the energy bill are the clearest signs that an attic-installed AC unit needs a professional look.

  • A musty odor or visible staining on the ceiling drywall below the attic
  • Cooling cycles that run longer than normal during peak summer heat
  • Higher than expected energy bills without any change in household usage
  • Weak airflow at the supply vents closest to the attic
  • Rust, cracking, or standing water in the primary or secondary drain pan

How to Protect an Attic AC Unit in Eden’s Climate

Insulating the attic, adding a secondary drain pan with a float switch, and scheduling seasonal maintenance are the most effective ways to protect an attic-installed AC unit in Eden’s climate.

  • Insulate and seal the attic access point and any exposed duct runs
  • Add a secondary drain pan with a float switch if the system does not already have one
  • Install a standalone water leak sensor near the unit for an added layer of protection
  • Schedule maintenance before peak summer heat arrives each year
  • Ask about mini-split or alternative placement options at the time of system replacement

Homeowners planning a full system replacement, or considering HVAC installation in Eden for the first time, should raise attic placement early in the conversation with their contractor rather than after the equipment has already been chosen.

Schedule Attic AC Service and HVAC Installation in Eden

An attic air conditioner installation does not have to be a liability. With the right insulation, a secondary drain pan, and regular seasonal maintenance, an attic-installed system can deliver years of reliable comfort in an Eden-area home. Homeowners who notice any of the warning signs above, or who are weighing a new system during a planned replacement, should have the current setup evaluated by a trained technician before a small issue becomes a costly one. Berico’s NATE-certified technicians work on attic-installed systems throughout Eden and the surrounding Rockingham County area, and they can recommend the right protections for a specific home.

People Also Ask: Attic AC Units in Eden, NC

Is it against code to install an AC unit in the attic?

Building codebooks generally do not prohibit attic-installed air conditioners, and it is a common configuration in Eden-area homes. Local code does typically require specific safeguards for attic installations, such as a secondary drain pan, a float switch, and adequate service access. A licensed contractor pulling permits for the work will confirm what the local inspection authority requires for a specific address, since requirements can vary by municipality even within the same region.

How hot does an attic get in the summer in Eden, NC?

An unconditioned attic in Eden can reach 130°F or higher during peak summer afternoons, especially under a dark asphalt shingle roof with limited ventilation. That heat load is one of the main reasons attic-installed AC units work harder and wear out components faster than systems placed in a basement or a conditioned closet. Proper insulation and attic ventilation can meaningfully reduce how hot the space gets.

Can attic heat void an AC unit’s warranty?

Extreme heat alone typically does not void a manufacturer’s warranty, since attic installation is a recognized configuration. However, damage caused by neglected maintenance, such as a system that overheated because a clogged filter or dirty coil went unaddressed, can fall outside warranty coverage. Keeping up with seasonal maintenance protects both the equipment and the warranty that comes with it.

Do attic AC units need a secondary drain pan?

Yes. A secondary drain pan paired with a float switch is considered a standard safeguard for any attic-installed air conditioner, since it catches condensate if the primary drain line clogs and shuts the system down before water reaches the ceiling. Homes without this safeguard are at meaningfully higher risk of water damage from a slow, unnoticed leak.

How often should an attic AC unit be serviced?

An attic-installed air conditioner should generally be serviced at least once a year, ideally before the start of the cooling season. Because attic units work in a harsher environment than systems in a basement or closet, some homeowners choose twice-yearly maintenance to catch drain pan issues, duct problems, or component wear before they turn into a larger repair.

What is a float switch and why does it matter?

A float switch is a small safety device installed in the drain pan that shuts the AC system off automatically if water rises above a set level, usually because the primary drain line has clogged. Without one, an unnoticed drain clog can allow condensate to overflow the pan and leak into the ceiling and walls below, sometimes for days before anyone notices.

Can a mini-split system avoid attic heat problems?

A ductless mini-split can reduce some attic-related issues since it does not rely on long duct runs that lose efficiency in extreme heat, and individual units can be placed outside the hottest part of the attic. It does not eliminate every consideration, though, and a technician can evaluate whether a mini-split or a traditional system makes more sense for a specific home’s layout.

How can homeowners tell if an attic AC unit is leaking?

The most common early sign is a stain or soft spot on the ceiling drywall directly below the unit, though a musty smell in an upstairs room can also point to a slow leak. Checking the primary and secondary drain pans for rust, cracking, or standing water during routine maintenance is the most reliable way to catch a leak before it causes visible damage.

Does insulating the attic help an AC unit run better?

Yes. Proper attic insulation reduces how hot the space gets, which lowers the temperature difference the AC unit has to fight against and reduces strain on its components. Insulating and sealing any duct runs in the attic also prevents cooled air from losing its temperature before it reaches the rooms below, which improves comfort and can lower energy bills.

Should an old attic AC unit be relocated during replacement?

It depends on the home’s layout and the condition of the existing ductwork. Some homeowners choose to keep the new system in the attic with upgraded insulation and drainage safeguards, while others use a full system replacement as an opportunity to consider a different location or a ductless mini-split. A technician can walk through the tradeoffs for a specific home before the replacement begins.

How Can You Tell If a Thermostat Is Bad Instead of the HVAC System Itself?

When heating or cooling stops working the way it should, the instinct is to assume the furnace or air conditioner itself has failed. In some cases, though, the equipment is fine, and the real problem sits at the wall: the thermostat.

Quick Answer: A bad thermostat usually follows one of a few clear patterns: the system does not respond to setting changes, it runs constantly without reaching the set temperature, the display goes blank, or the temperature it reports does not match how the room actually feels. Ruling out the mode setting, the set point, and the circuit breaker first can catch a simple fix before assuming the thermostat has failed.

Indications That a Thermostat Is Bad

The clearest indications that a thermostat is bad, rather than the HVAC system itself, are a system that will not respond to setting changes, a system that runs nonstop, a blank display, or a reported temperature that plainly does not match the room.

Some of the signs of a bad thermostat include the system not responding when the settings are adjusted, the system running constantly without ever reaching the right temperature, or the display going completely blank. Ruling out a few simple issues first can solve the problem before a service call is ever needed.

Start with the Basics

Before assuming the thermostat or another part of the HVAC system has failed, a few basic checks can rule out simple causes in minutes.

Before assuming the thermostat is failing, or that something else in the HVAC system is at fault, a couple of basic things are worth double-checking. First, confirm the thermostat is set to the correct mode, heating or cooling. Next, confirm the set temperature is actually above or below the current temperature in the house, depending on which mode is in use. Finally, check the circuit breaker. A tripped breaker can look exactly like a dead thermostat, and the fix is nothing more than resetting it.

Symptoms That Point to Thermostat Trouble

A handful of specific symptoms point clearly to the thermostat rather than the furnace or air conditioner itself, and each one has a distinct mechanical explanation.

  • System will not turn on or off. When adjusting the settings makes no difference at all, the thermostat has likely lost its connection to the equipment. That can mean a wiring fault, a dead battery in a wireless unit, or a failed control board, and each of those calls for a different fix.
  • System runs constantly. The system runs and runs with no end in sight. This usually means the thermostat is not reading the room’s temperature correctly, so it never registers that the set point has been reached and keeps calling for heating or cooling long after the room is comfortable.
  • Display is blank. A blank screen that does not respond even after fresh batteries points to a failed unit. That is different from a screen that just looks dim or hard to read, which is more often a battery or connection issue than a failed display.
  • Temperature readings are clearly wrong. Sometimes the mismatch is obvious without any tools at all. If the thermostat reads 70°F but the room feels scorching, the internal sensor has drifted out of calibration, and the unit can no longer read the room accurately, no matter how it is set.

What an Experienced Technician Checks First

An experienced technician typically checks the thermostat’s wiring connections and sensor calibration before assuming a furnace or air conditioner component has failed, since a miscommunication at the thermostat can mimic almost any HVAC symptom.

ā€œA furnace or AC that looks like it is failing is often just a thermostat that stopped communicating correctly. Before touching the equipment, I check the wiring at the thermostat base and test how accurately it reads the room, because a small sensor problem can look exactly like a compressor or control board failure if nobody checks the simple things first.ā€

How Older Wiring and Piedmont Humidity Affect Thermostat Accuracy

Homes with older wiring or original mechanical thermostats are more likely to develop the connection and calibration issues described above, since older components simply have more time and more failure points behind them.

In older Greensboro neighborhoods such as Fisher Park, College Hill, and Irving Park, homes built before modern wiring standards are more likely to still be running original mechanical thermostats or aging wiring runs, which makes these problems more common than in newer construction. Piedmont summers also bring long stretches of high humidity, and humidity swings inside a thermostat’s housing can accelerate the kind of sensor drift described above, particularly in older units without sealed electronics.

Repair or Replace: What Actually Makes Sense

A wiring or connection issue is often a straightforward repair, while a failed sensor, a dead control board, or a worn-out mechanical thermostat usually calls for replacement rather than repair.

A loose wire or a dead battery is typically a quick fix. A control board failure, a drifted sensor, or a mechanical thermostat that has simply reached the end of its service life is a different story, and continuing to chase small repairs on a unit like that usually costs more over time than replacing it once. A technician can confirm which category a specific problem falls into during a single diagnostic visit.

People Also Ask: Bad Thermostat Signs

Can a bad thermostat make an AC or furnace seem broken when it isn’t?

Yes. A thermostat that has lost its connection to the equipment, or that is misreading the room’s temperature, can produce symptoms that look identical to a failing furnace or air conditioner, such as short cycling, no response to setting changes, or a system that never seems to reach the target temperature. A technician can usually tell the difference within a single diagnostic visit.

How can homeowners tell whether it’s the thermostat or the HVAC system?

The clearest signals are a system that does not respond at all to setting changes, one that runs constantly without reaching the set temperature, a blank display, or a room temperature that obviously does not match what the thermostat reports. If the outdoor unit or furnace runs normally once manually triggered, the thermostat is the more likely culprit.

Can a tripped breaker be mistaken for a dead thermostat?

Yes, and it happens easily. A tripped circuit breaker can cut power to the thermostat entirely, producing a blank screen or a completely unresponsive unit that looks identical to a genuine thermostat failure. Checking the breaker panel first is a simple step that can rule out this cause in under a minute.

What does it mean when the thermostat display is blank?

A blank display usually points to a power interruption, such as dead batteries, a tripped breaker, or a loose wiring connection, though it can also mean the unit itself has failed. Replacing the batteries and checking the breaker are the first steps before assuming the thermostat needs to be replaced.

Why does a thermostat lose accuracy over time?

Internal sensors can drift out of calibration as components age, and that drift means the thermostat’s displayed temperature no longer matches the room’s actual temperature. This is more common in older mechanical thermostats than in newer digital or smart models, since sealed electronic components tend to hold their calibration longer.

Can a bad thermostat run up energy bills?

Yes. A thermostat that cannot accurately sense when the set temperature has been reached will keep calling for heating or cooling long after it is needed, which drives up runtime and energy use without improving comfort. This is one of the more common financial costs of an unnoticed thermostat problem.

Is a thermostat problem usually a simple repair or a full replacement?

It depends on the cause. A loose wire or a dead battery is typically an easy repair, while a failed sensor, a bad control board, or an aging mechanical thermostat usually makes more sense to replace outright. A technician can confirm which situation applies during a diagnostic visit.

How long do thermostats typically last?

Service life varies by type and usage, but thermostats are electronic and mechanical devices that wear over time like any other HVAC component. Older mechanical units in particular tend to need replacement sooner than modern digital or smart thermostats, which generally hold calibration and connectivity longer.

Can humidity or old wiring affect thermostat performance in the Piedmont Triad?

Yes. Long stretches of high humidity during Piedmont summers can affect the internal components of an older thermostat, particularly units without sealed electronics, and aging wiring in older homes adds another point where connections can loosen or fail over time.

Should a homeowner replace a thermostat themselves?

Basic thermostat swaps are within reach for some homeowners, but confirming that the thermostat, and not the HVAC system’s wiring or control board, is actually the source of the problem is where a professional diagnosis adds the most value. Getting that diagnosis wrong can mean paying for a new thermostat that does not fix the underlying issue.

What Is a Package HVAC Unit and How Is It Different From a Split System?

Best time of year to service your HVACIf you’re shopping for new heating and air conditioning equipment, you may run into a term that doesn’t come up often: package unit. It sounds like it could mean almost anything, so it’s worth taking a minute to explain exactly what it is and why a contractor might bring it up for your home.

Quick Answer: A package HVAC unit is a single outdoor cabinet that houses all of your heating and cooling equipment in one place, usually on a concrete slab or a rooftop. A split system, which is what most Greensboro homes use, keeps the furnace or air handler inside the house and only the condenser outside. Package units show up most often in homes without a basement, attic, or mechanical closet to hold an indoor unit, such as mobile homes and slab-on-grade construction.

A Package Unit Puts Everything in One Outdoor Cabinet

A package unit is self-contained, meaning your heating and cooling equipment lives together in a single outdoor cabinet instead of being split between an indoor and outdoor component. That cabinet gets installed on a concrete slab near the home or, less commonly for residential properties, up on a rooftop.

This setup exists for one main reason: some homes simply don’t have anywhere to put an indoor air handler. If there’s no basement, no attic access built for HVAC equipment, and no mechanical closet, a package unit lets you skip that problem entirely by keeping everything outside.

How a Package Unit Compares to a Traditional Split System

A split system separates your equipment into two locations, and that separation is exactly what makes it the more common choice in this area. The outdoor unit, the condenser, handles heat exchange with the outside air. The indoor unit, the air handler or furnace, conditions the air and pushes it through your ductwork. Refrigerant lines and electrical wiring run between the two, tying them together into one system.

Keeping the air handler indoors matters more here than homeowners often realize. Greensboro summers bring heavy humidity, and indoor equipment doesn’t have to fight that moisture directly the way outdoor equipment does. Winter cold snaps are easier on components that are sitting inside a conditioned space rather than exposed to freezing air overnight. That’s a big part of why split systems are the default recommendation for most homes in this area, and why experienced technicians only reach for a package unit when the layout of the home actually calls for it.

Why Package Units Show Up in Certain Homes

Package units aren’t a downgrade. They solve a specific problem, and that problem usually comes down to available space. A mobile home rarely has the structural design to fit an indoor air handler and a proper duct run. Slab-on-grade homes without a basement or crawlspace face the same limitation. In both cases, a package unit gives the home a full heating and cooling system without needing to carve out indoor mechanical space that was never part of the original design.

The Tradeoffs Worth Understanding

Every package unit sits outside year-round, and that constant exposure is the single biggest factor in how long the system lasts and how well it performs. Heat, humidity, freezing temperatures, and the heavy pollen season this region sees every spring all land directly on equipment that a split system would keep protected indoors. Technicians who service package units regularly see coil corrosion and drainage issues show up sooner than they would on comparable indoor equipment, simply because there’s no roof over the cabinet.

Efficiency tends to run a step behind split systems too. It’s not that package units are poorly built. It’s that consolidating everything into one outdoor cabinet creates some inherent limitations that a separated system doesn’t have to work around.

None of this means a package unit is the wrong call. When a split system genuinely isn’t practical for a home, a package unit still delivers reliable comfort. It just comes with a maintenance rhythm that shouldn’t be skipped. Homeowners who stay current on seasonal service tend to get much closer to the equipment’s full expected lifespan than homeowners who treat it like a set-and-forget appliance.

How Berico Can Help

Whatever your home’s layout calls for, a traditional split system, a ductless mini-split, or a package unit, Berico can walk you through what actually makes sense for your space before any equipment goes in the ground. We’ve been part of this community since 1924, and that long history means we’ve seen how different home types across Greensboro, Burlington, and Eden hold up over the years with each type of system.

ā€œThe homes that get the longest life out of a package unit are almost always the ones on a regular maintenance schedule,ā€ says Darrel Honeycutt, Expert HVAC Technician at Berico. ā€œSkipping a season or two of service is where we start seeing coil damage that could have been caught early.ā€

If you’re planning a new HVAC installation and aren’t sure which setup fits your home, reach out and we’ll help you figure it out.

Key Takeaways

Most homes in the Greensboro area use a split system, with the air handler indoors and the condenser outside, and that’s usually the better choice when there’s a place to put it. Package units earn their place in homes without a basement, attic, or mechanical closet, most often mobile homes and slab-on-grade construction. The tradeoff is that everything sits outside year-round, which shortens component lifespan and trims efficiency compared to a split system, but a well-maintained package unit still keeps a home comfortable through every season.

People Also Ask

Are package HVAC units good for North Carolina’s climate?

They can work well, but the heat, humidity, and pollen this region sees each year put more stress on outdoor equipment than a split system would face. A package unit installed here needs a consistent maintenance schedule to hold up against those conditions, especially through the humid summer months.

Can a package unit be converted to a split system?

In some cases, yes, but it depends on whether the home has a place to put an indoor air handler and whether ductwork can be rerouted to support it. This isn’t a simple swap, and it usually requires a full evaluation of the home’s mechanical space before a contractor can say whether it’s practical.

Do package units cost more to maintain than split systems?

Package units generally need more frequent attention because the equipment is exposed to the weather year-round. Coils, drainage, and electrical connections tend to need earlier inspection than the same components would on an indoor air handler, so staying current on seasonal service matters more with this setup.

How long do package HVAC units last?

Lifespan varies by usage and maintenance, but constant outdoor exposure typically means package units don’t last quite as long as comparable split systems. Homes that keep up with regular seasonal service tend to get much closer to the equipment’s full expected lifespan than homes that skip maintenance.

Is a package unit noisier than a split system?

Both systems produce similar operating noise, but a package unit’s noise source sits entirely outside the home since all the equipment, including the blower, is in one outdoor cabinet. Depending on where it’s placed, that can actually mean less noise indoors compared to a split system with an air handler in a closet or attic near living space.

What size home is a package unit best suited for?

Package units are sized the same way any HVAC system is sized, based on square footage, insulation, layout, and local climate, not a specific home size category. The decision to use a package unit instead of a split system comes down to available mechanical space, not the size of the home itself.

Can a package unit be installed on a roof for a residential home?

Rooftop placement is more common for commercial buildings than homes, but it’s occasionally used for additions or homes where ground placement isn’t practical. Most residential package units sit on a concrete slab near the home rather than on the roof.

Do package units work for both heating and cooling?

Yes. A package unit can be built to handle heating and cooling in one cabinet, similar to how a split system pairs a furnace or heat pump with an air conditioner. The equipment inside the cabinet varies depending on whether the unit uses gas heat, electric heat, or a heat pump.

Why don’t more homes in Greensboro use package units?

Most homes here have a basement, attic, or mechanical closet that makes a split system the more practical and typically longer-lasting option. Package units become the better fit mainly when that indoor mechanical space simply doesn’t exist, which is less common in traditional home construction than in mobile homes or slab-on-grade builds.

Is a ductless mini-split a type of package unit?

No. A ductless mini-split is its own category, using an outdoor condenser connected to one or more small indoor units without traditional ductwork. A package unit still relies on a duct system to distribute air, it just houses all the equipment outdoors instead of splitting it between indoor and outdoor components.

When Should I Install a Whole House Generator?

When Should You Install a Whole House Generator in Burlington?

Power outages in Burlington rarely give much warning. An ice storm moves through in January, a summer thunderstorm knocks a limb into a line, or a piece of aging equipment on the grid fails on an ordinary Tuesday afternoon. In most cases, the lights come back within a few hours. Some years, they don’t.

The real question homeowners need answered isn’t whether a whole house generator is a good idea. It’s whether now is the right time to schedule a Burlington generator installation, and what actually needs to happen to get the installation done correctly.

Quick Answer: The best time to install a whole house generator is before you need it, not during an outage. Homeowners with medical equipment, home offices, or properties prone to frequent outages benefit most from a standby generator and see the fastest payoff. Once you decide to move forward, the installation itself depends on correct sizing, the right fuel source, and proper integration with your home’s electrical panel, work that should always be handled by a licensed electrician.

Why Waiting on a Generator Decision Might Cost More

Waiting can cost more, since generator demand spikes the moment bad weather hits and installation isn’t something that happens same day.

Every homeowner who calls an electrician in the middle of a multi-day outage is asking for the same thing everyone else on the street just asked for. Supply houses run low on units, installation schedules fill up, and permitting offices get backed up with requests. None of that is a pricing tactic. It’s simply what happens when a whole neighborhood decides at the same time that it needs power.

A generator installation involves a site evaluation, an electrical load calculation, permitting, and in most cases a fuel line installation if you’re running on natural gas or propane. None of that happens in a single afternoon. Homeowners who plan ahead of a weather event get to schedule installation on a normal timeline. Homeowners who wait until the power is already out are choosing to compete for the same limited slots as everyone else.

The Homeowners Who Benefit Most From a Standby Generator

Not every home needs a whole house generator, and a good electrician will tell you that directly instead of trying to sell you one anyway. Generators earn their cost when they solve a specific, ongoing problem rather than a hypothetical one.

Homes With Medical Equipment or Refrigerated Medication

This is the situation where a generator stops being a convenience and becomes closer to a necessity. Oxygen concentrators, CPAP machines, and powered mobility equipment all need consistent electricity, and a battery backup only buys a few hours at best. The same is true for insulin or other medications that require refrigeration. If anyone in the household depends on powered equipment or cold storage for health reasons, a whole house generator removes a real risk rather than just an inconvenience.

Remote Workers and Home-Based Businesses

If your income depends on a working internet connection and a functioning computer, a two or three day outage isn’t just annoying. It’s lost income, missed deadlines, and in some cases lost clients. For homeowners in this position, a generator often pays for itself the first time it prevents a missed workday, and it keeps paying off every outage after that.

Properties With a History of Frequent Outages

Some streets in Burlington lose power more often than others, usually because of tree coverage, older utility lines, or a substation that struggles during heavy load. If your home has a track record of going dark every time there’s a strong storm, that history is the best predictor of what’s coming. A generator on a property like this isn’t a luxury. It’s addressing a pattern that’s already been established.

Homeowners without one of these specific needs can still benefit from a generator, but the decision usually comes down to comfort and not having to think about outages rather than necessity. That’s a legitimate reason to move forward. It just changes the urgency, not the value.

Why Burlington’s Weather and Power Grid Make This Worth Planning For

Burlington sits in a part of the state that gets hit from more than one direction. Winter brings the occasional ice storm that coats power lines and tree limbs until something gives way. Summer brings strong thunderstorms and the remnants of tropical systems that roll through the Piedmont with heavy wind and rain. Add in a mature tree canopy across most established Burlington neighborhoods, and you have a lot of overhead line exposed to falling limbs every time the wind picks up.

A good number of homes in the Burlington area also carry electrical panels and service that are decades old. Older infrastructure, both on the utility side and inside the home, tends to fail sooner under stress than newer systems. None of this means every outage is a crisis. It does mean that outages here aren’t rare, isolated events. They’re a predictable part of living in this region, which is exactly why planning ahead of time matters more here than it might somewhere with a more modern grid and less tree cover.

Getting the Installation Right

Buying a generator and having it installed correctly are two different projects. A generator that’s undersized, misfueled, or improperly tied into your electrical system won’t perform the way you expect when you actually need it.

Natural Gas or Propane

One of the first decisions in any generator project is fuel source. Natural gas works well for homes that already have gas service running to the property, since it draws directly from the existing line with no tank to monitor or refill. Propane is the better option for homes without natural gas access. A propane tank can be installed on the property specifically to fuel the generator, and it gives you a reliable, self-contained fuel source that doesn’t depend on a utility connection at all.

Neither option is universally better. The right choice depends on what’s already available at your home and how you want to manage fuel long term.

Correct Sizing

A generator that’s too small won’t carry your home’s full electrical load, which means certain circuits or appliances get cut out during an outage even though the generator is running. A generator that’s oversized costs more upfront and burns fuel less efficiently than it should. Correct sizing comes from an actual load calculation on your home’s electrical panel and circuits, not a guess based on square footage. This is one of the areas where experience matters. An electrician who has sized dozens of these systems will catch details that a generic online sizing calculator won’t.

Electrical Integration

The generator also needs to tie into your home’s electrical system through a transfer switch, which is what allows the generator to take over automatically when utility power drops and hand control back once it’s restored. This connection has to be done correctly and to code, both for safety and so the system performs the way it’s supposed to during an actual outage. This part of the project should never be handled as a shortcut.

What to Expect When You Call Berico

Berico has served homeowners throughout Greensboro, Burlington, and Eden since 1924, and the company now offers professional electrical services, including standby generator sales, installation, and maintenance. When you call, a trusted Burlington electrician will walk your property, look at your existing panel and service, talk through your specific reasons for wanting a generator, and help you land on the right size and fuel type for your situation. There’s no pressure to buy more generator than you need.

ā€œThe homeowners who are happiest with their generator years later are the ones we sized correctly the first time, not the ones who bought the biggest unit available,ā€ says Toni Mortera, Expert Electrician at Berico. ā€œGetting the load calculation right up front saves people money and headaches for the life of the system.ā€

Key Takeaways

A whole house generator makes the most sense for homes with medical needs, remote work income, or a history of frequent outages, though plenty of other homeowners choose one simply because they don’t want to worry about the next outage. Burlington’s weather patterns and tree cover mean outages here are a predictable part of living in the area, not a rare event. Once you decide to move forward, the project comes down to three things: the right fuel source, correct sizing based on an actual load calculation, and a properly installed transfer switch.

Waiting until a storm is already bearing down puts you in line behind everyone else who waited too. Planning ahead means you get the installation done on a normal schedule, sized correctly, before you ever need to rely on it.

If you’re ready to talk through your options, Berico’s electrical team can walk your property, answer your questions, and help you figure out what makes sense for your home.

People Also Ask

How much does a whole house generator cost to install?

Cost depends on the generator’s size, the fuel type, and how much electrical work is needed to tie it into your home’s panel. Homes needing a new propane tank or significant electrical upgrades will cost more than homes with existing natural gas service and a modern panel. The only accurate way to get a number for your home is a site evaluation, since square footage alone doesn’t determine what your home actually needs.

How long does a whole house generator installation take?

The physical installation typically takes one to two days once the equipment is on site, though the full process, including the site evaluation, permitting, and any required fuel line work, usually takes longer. Homes needing a new propane tank or panel upgrades will need additional time before installation day.

Do I need a permit to install a standby generator?

Yes. Most municipalities, including Burlington, require an electrical permit and inspection for a whole house generator installation. A licensed electrician handles the permitting process as part of the installation, so this isn’t something homeowners need to manage on their own.

Can a whole house generator run my entire home?

It depends on how it’s sized. A generator sized for your home’s full electrical load can run everything, including HVAC, well pumps, and major appliances. A smaller unit may be set up to run only essential circuits. This is decided during the load calculation, not after installation, so it’s worth being clear about your expectations before the unit is chosen.

How often does a standby generator need maintenance?

Most manufacturers recommend an annual maintenance visit, similar to servicing a furnace or air conditioner. Regular maintenance checks the battery, oil, fuel connections, and transfer switch to make sure the system will actually start and run when it’s needed, which is the entire point of having one.

What’s the difference between a whole house generator and a portable generator?

A whole house generator is permanently installed, runs on natural gas or propane, and starts automatically within seconds of a power outage through a transfer switch. A portable generator has to be manually set up, fueled, and connected each time it’s used, and it typically can’t power an entire home’s electrical load. Portable units work for short-term, limited needs, but they aren’t a substitute for a properly installed standby system.

Will a generator work during an extended multi-day outage?

A natural gas generator can run for as long as the gas utility keeps supplying fuel, since it isn’t limited by tank size. A propane generator will run until the tank runs low, so tank size matters for homeowners who expect longer outages. Either option is built to run continuously for days if needed, unlike a portable generator that requires frequent refueling and monitoring.

Should I get a generator if my power rarely goes out?

If your home doesn’t have medical needs, remote work income at stake, or a history of frequent outages, a generator becomes more about comfort and preparedness than necessity. That’s still a valid reason to install one. It just means the decision comes down to how much you value not having to think about it when the next storm rolls through.

Does a generator increase my home’s value?

A whole house generator is generally viewed as a valuable feature by buyers, particularly in areas prone to outages, but it’s not typically categorized the same way as a kitchen or bathroom renovation. Most homeowners install one for their own use rather than as a resale strategy, though it rarely hurts a home’s marketability.

What size generator do I need for my house?

The right size comes from a load calculation based on your home’s specific electrical panel, circuits, and the appliances you want to keep running, not from a generic chart based on home square footage. An electrician can walk through this with you and explain exactly what’s driving the recommendation, so you understand why a particular size makes sense for your home.

What’s the Difference Between AFUE and SEER Ratings?

If you’re shopping for new heating and cooling equipment, you’re going to run into two ratings that trip up almost every homeowner at first: AFUE and SEER. They sound similar, they both measure efficiency, and it’s easy to assume they mean roughly the same thing. They don’t, and knowing the difference can change which upgrade actually saves you the most money.

Quick Answer: AFUE (Annual Fuel Utilization Efficiency) measures how efficiently a furnace or boiler converts fuel into heat. SEER (Seasonal Energy Efficiency Ratio) measures how efficiently an air conditioner or heat pump cools your home over a season. AFUE applies to heating equipment, SEER applies to cooling equipment, and in the Greensboro area, SEER usually has a bigger impact on your utility bills since your Greensboro AC system works harder for more months of the year than your furnace does.

What AFUE Measures and Why It Matters

AFUE tells you how much of the fuel your furnace burns actually turns into heat for your home, expressed as a percentage. A furnace with a 95% AFUE converts 95% of its fuel into usable heat, with the remaining 5% lost through exhaust and normal combustion inefficiency.

That lost energy is the part homeowners often don’t think about until it’s explained plainly: you’re paying for 100% of the fuel, but an older or lower-efficiency furnace might only turn 80% of it into heat you actually feel. The other 20% goes straight out the flue. That gap is why furnace age and AFUE rating matter more than most people expect when a heating bill feels higher than it should.

What Counts as a Good AFUE Rating

An AFUE in the 80% range is considered standard efficiency and is still common in older furnaces. Getting into the 90% range and higher puts you into high-efficiency territory, where you’re losing far less energy to combustion waste and typically seeing a noticeable drop in monthly heating costs. Furnaces at this level usually also use a different combustion design that traps more heat before it escapes, which is part of why the jump from 80% to 95% AFUE feels bigger in practice than the ten to fifteen point difference suggests.

What SEER Measures and Why It Matters

SEER measures how much cooling your air conditioner or heat pump produces over an entire season compared to the electricity it consumes. The higher the SEER rating, the less electricity your system needs to keep your home comfortable, and the lower your cooling costs tend to run.

Older systems that have been running for a decade or more often carry a SEER rating around 10, which is well below what’s even sold today. Current federal efficiency standards mean any new unit you buy will carry a SEER rating of at least 15, and homeowners who want to go further can find high-efficiency systems ranging from 18 up to 25.

Why a Higher SEER Rating Doesn’t Automatically Mean Lower Bills

This is where a lot of homeowners get surprised. A high-SEER system installed with the wrong ductwork, incorrect refrigerant charge, or a unit that’s oversized for the home won’t deliver anywhere close to its rated efficiency. Technicians who install a lot of high-efficiency equipment see this constantly: the equipment gets the upgrade, but the installation details get overlooked, and the homeowner never sees the savings they expected. The rating on the box only reflects what the system is capable of under ideal conditions. Getting there depends just as much on correct sizing and a clean installation as it does on the equipment itself.

Why SEER Usually Matters More Than AFUE Here

In the Greensboro area, air conditioners and heat pumps run for a longer stretch of the year than furnaces do, simply because of how the seasons break down locally. Summers here are long, humid, and demanding on cooling equipment, while winters bring shorter stretches of real heating need, punctuated by occasional cold snaps rather than months of sustained cold. That workload difference is exactly why, if you can only afford to upgrade one system this year, most homeowners in this area see a faster return from improving their SEER rating than their AFUE rating.

That doesn’t mean AFUE stops mattering. A furnace working through a January cold snap on an 80% AFUE rating is still burning more fuel than it needs to. It just means the math usually favors the cooling side first in this particular climate.

How Berico Can Help

Are you looking for HVAC contractors you can trust to explain what these ratings actually mean for your home, not just recite the numbers? Berico’s technicians handle air conditioner repair, furnace evaluations, and full system replacements, and they’ll walk you through what rating makes sense for your budget and your home’s specific setup before recommending anything.

ā€œThe AFUE or SEER number on the equipment only tells half the story,ā€ says Darrel Honeycutt, Expert HVAC Technician at Berico. ā€œWe’ve walked into homes with a beautiful 20 SEER system that was never sized right for the house, and the homeowner was still paying high bills. Getting the rating right only matters if the installation backs it up.ā€

Key Takeaways

AFUE measures heating efficiency, SEER measures cooling efficiency, and both matter, but they solve different problems. In the Greensboro area, cooling equipment typically runs longer and harder over the course of a year, which usually makes SEER the priority if you’re deciding where to invest first. Either way, the rating on the equipment is only part of the story. Correct sizing and a clean installation are what actually determine whether you see the efficiency you paid for on your utility bill.

People Also Ask

What is a good AFUE rating for a furnace?

An AFUE of 90% or higher is considered high efficiency and typically delivers noticeably lower heating costs compared to standard efficiency furnaces in the 80% range. Furnaces below 80% AFUE are increasingly rare in new equipment and generally indicate an older, less efficient system.

What is a good SEER rating for an air conditioner?

Since federal efficiency standards require a minimum SEER of 15 for new equipment, anything you buy today already starts at a reasonably efficient baseline. High-efficiency systems in the 18 to 25 range offer further savings, particularly in climates where cooling equipment runs for a large part of the year.

Does a higher SEER rating always lower my electric bill?

Not automatically. A high-SEER system only delivers its rated efficiency when it’s sized correctly for the home and installed properly, including correct refrigerant charge and ductwork. A high-efficiency unit installed poorly can perform closer to a lower-rated system in real-world use.

Should I prioritize AFUE or SEER when upgrading my HVAC system?

It depends on your climate and which system is older or less efficient. In areas with long, demanding cooling seasons like Greensboro, SEER often has the bigger impact on your bills, but a furnace with a low AFUE rating working through cold snaps is still worth addressing.

How often should I replace my furnace or air conditioner based on efficiency?

There’s no fixed timeline, but a heating or cooling system beyond 12 to 15 years old is often operating well below the AFUE or SEER rating of equipment sold today. A comfort evaluation can show whether your current system’s efficiency loss justifies replacing it now versus waiting.

Can I improve my SEER rating without replacing my whole system?

Not in the way most homeowners hope. SEER is a rating tied to the specific equipment, so you can’t meaningfully raise it without replacing the unit. However, correcting issues like poor duct sealing, low refrigerant charge, or a dirty coil can help your existing system perform closer to its original rated efficiency.

Do heat pumps have both an AFUE and a SEER rating?

Heat pumps are rated with SEER for cooling performance and a separate rating called HSPF for heating performance, rather than AFUE, since they use electricity and refrigerant instead of burning fuel. AFUE only applies to combustion-based heating equipment like furnaces and boilers.

Is it worth paying more for a higher SEER or AFUE rating upfront?

It depends on how long you plan to stay in the home and how much your current system is costing you to run. Homeowners who plan to stay long term and have an older, inefficient system typically recover the higher upfront cost through lower utility bills over time, though the payoff timeline varies by home and usage.

Why did my new high-efficiency system not lower my bills as much as expected?

This usually points back to installation rather than the equipment itself. Incorrect sizing, duct leakage, or an improper refrigerant charge can all prevent a high-SEER or high-AFUE system from performing at its rated efficiency, even though the equipment itself is capable of it.

What’s the minimum SEER rating allowed for new air conditioners?

Current federal efficiency standards require a minimum SEER rating of 15 for new residential air conditioning equipment. Older systems installed before these standards took effect may carry a much lower rating and are typically far less efficient by comparison.

Why Is My Shower Not Staying Hot?

When a shower runs hot for a few minutes and then turns cold, the problem usually traces back to one of four water heater issues: undersized tank capacity, a failing heating element or burner, sediment buildup, or a faulty thermostat. Understanding which issue applies to a specific home points directly toward the right repair.

That question, simple as it sounds, sends a lot of Greensboro homeowners searching for answers in the middle of a rinse cycle. The answer is not always straightforward because several different components can cause the same symptom. The sections below break down each cause, explain what is happening inside the unit, and describe what a licensed plumber will look for when diagnosing the problem.

Why a Shower Starts Hot and Then Goes Cold

If a shower starts out hot but quickly turns lukewarm or even cold, the water heater may be too small for the demands of the home. Other issues can include a failing heating element or burner, sediment buildup in the tank, or a faulty shower mixing valve.

The key distinction to make first is whether the problem happens at the beginning of a shower or partway through. If the water is cold from the start, the issue is almost always with the heater itself. If the water starts hot and fades, the tank is likely running out of stored hot water before the shower is finished, or a component is failing mid-operation.

Common Water Heater Problems That Cause Cold Showers in Greensboro

Capacity Is Too Small

A tank that is undersized for the household will run out of hot water before all users and fixtures are done using it. This is only a factor for traditional tank water heaters.

When the tank is not big enough to serve the number of users and fixtures in the house, it will run out of supply before everyone is done using it. A family of four in a Greensboro home with a 30-gallon tank is likely outpacing supply on mornings when multiple people shower back to back. The standard guidance for tank sizing is 10 to 15 gallons per person in the household, though actual demand varies based on shower length and simultaneous fixture use.

Failing Heating Element or Burner

In an electric water heater, a failing heating element allows water temperature to drop during use because the element cannot maintain consistent heat output as it degrades.

There is a heating element that raises the temperature of the water in an electric water heater. In a gas model, there is a burner. Either way, if this component is not working as it should, or as well as it used to, the water might not stay hot throughout a shower.

Electric water heaters typically have two elements, one near the top of the tank and one near the bottom. When the lower element fails, the heater still warms the upper portion of the tank, so the first few gallons feel hot. Once that top layer is used, cold water takes over. A plumber can test element resistance with a multimeter to confirm failure.

Sediment Buildup in the Tank

Sediment buildup reduces effective tank capacity and insulates the heating element from the water, forcing the unit to work harder while delivering less consistent heat output.

This is another issue that only relates to traditional tank models. Over time, minerals from the water can accumulate in the bottom of the tank, taking up space and effectively reducing the interior volume. This not only cuts down on capacity, but it also makes it harder for the heating element or burner to warm up the water.

Greensboro’s municipal water supply carries dissolved minerals, primarily calcium and magnesium, that precipitate out of solution as water is heated repeatedly. In older homes, where the water heater may not have been flushed in years, sediment layers can be significant. A plumber flushing the tank will often see discolored water and visible mineral flakes. Annual flushing is a straightforward maintenance step that extends tank life and keeps performance consistent.

Faulty Thermostat

A failing water heater thermostat sends incorrect signals to the heating components, causing the water temperature to fall below the set point during a shower.

Sometimes the issue is as simple as a failing thermostat not sending the right message to the rest of the unit. The thermostat is supposed to keep track of the temperature of the water and tell the heating components when they should be running. If there is something wrong with the thermostat, that heating process will not work as it should.

Electric water heaters have separate thermostats for each element. Either one can fail independently. Gas units typically have a single thermostat integrated into the gas valve assembly. In both cases, thermostat failure is often confirmed by checking whether the set temperature on the dial matches actual water output temperature at the tap.

Faulty Shower Mixing Valve

A worn or malfunctioning mixing valve inside the shower itself can allow cold water to bleed into the hot supply line, causing temperature fluctuations that mimic a failing water heater.

This is a component that is easy to overlook because it is inside the wall rather than at the water heater. The mixing valve blends hot and cold water to deliver the temperature selected at the handle. When the valve cartridge wears out, it can lose the ability to maintain that ratio. The result is inconsistent temperature at the showerhead, even when the water heater is functioning normally. If a plumber inspects the water heater and finds it in good working order, the mixing valve is the next logical point of investigation.

“Adam Rhodes, Licensed Master Plumber at Berico, has this perspective on Greensboro homes: ‘One thing I see often in older Greensboro neighborhoods is that homeowners replace the water heater when the real problem is the mixing valve. Before assuming the heater is the issue, it helps to check whether the problem is isolated to one shower or affects multiple fixtures throughout the house. If hot water is fine at the kitchen sink but fades in the shower, the valve is likely the culprit rather than the tank.’

The Matter of Water Heater Aging

No water heater will last forever. Like all other pieces of equipment, the traditional or tankless water heater that serves a home is going to wear down over time, gradually struggling more and more to keep up with demand. Traditional tank water heaters often last from 8 to 12 years, while tankless models will often last somewhat longer.

If a water heater has been in service for more than a decade, age-related decline is a reasonable explanation for deteriorating hot water performance. The components wear, the tank may develop minor corrosion, and the efficiency of the unit drops. At that point, repair addresses symptoms but does not resolve the underlying condition of an aging unit.

Checking the age of a water heater is straightforward: the manufacture date is encoded in the serial number on the data plate affixed to the unit. Most manufacturers use the first letter to represent the month and the following two digits to represent the year of manufacture.

Repair or Replace: How to Think Through the Decision

Deciding between repairing a water heater and replacing it depends on the unit’s age, the cost of the repair relative to replacement, and whether the existing unit is properly sized for current household demand.

A useful general guideline: if the repair cost exceeds 50 percent of the cost of a comparable new unit and the water heater is more than seven years old, replacement often makes more financial sense over the long term. A new unit comes with warranty coverage, improved energy efficiency ratings, and a fresh service life.

When considering replacement, Berico installs electric, gas, and tankless water heaters. Tankless models heat water on demand rather than maintaining a stored tank, which eliminates the risk of running out during back-to-back showers. They also typically have longer service lives than tank models. A Berico plumber can evaluate the existing system and discuss which replacement option fits the household’s usage patterns.

Signs Beyond Temperature Loss That Warrant a Call to a Plumber

Water temperature problems are the most common symptom homeowners notice, but other signs also indicate a water heater that needs professional attention.

  • Loud noises. If there are loud noises coming from the water heater area that are not typical during normal operation, that is a signal worth investigating. Rumbling or popping sounds often indicate significant sediment accumulation.
  • A drop in water pressure. When the hot water side of a faucet or showerhead delivers noticeably less pressure than the cold side, corrosion or sediment buildup in the supply lines or tank may be restricting flow.
  • Lack of consistent warm flow. Another potential sign of a problem is when the hot water keeps cutting out. Again, this might be noticed first in the shower as the temperature periodically drops to cold before rebounding.
  • Discolored or rusty water. Rust-colored hot water often means the tank’s interior lining is deteriorating, which is a sign that replacement is approaching.
  • Water pooling around the base of the unit. Any visible moisture around the tank should prompt an immediate call to a plumber. A leaking tank generally cannot be repaired and requires replacement.

Frequently Asked Questions About Hot Water Problems in Greensboro

How long does it take for hot water to come back after it runs out?

Recovery time depends on whether the unit is a tank or tankless model and the fuel source. A standard 40-gallon electric tank typically takes 60 to 80 minutes to fully reheat. A gas tank of the same size usually recovers in 30 to 40 minutes. A tankless unit produces hot water on demand with no recovery wait time, provided it is properly sized for the flow rate being requested.

Can a water heater be too large for a household?

An oversized tank is not a performance problem the way an undersized tank is, but it does represent an efficiency loss. The unit heats and maintains a larger volume of water than the household uses, which results in unnecessary standby energy consumption. Proper sizing by a licensed plumber avoids this outcome when a new unit is installed.

What is the difference between a tank and tankless water heater for a Greensboro home?

A traditional tank water heater stores a fixed volume of hot water, typically 30 to 80 gallons, and maintains that temperature continuously. A tankless water heater heats water as it flows through the unit, with no storage tank. Tankless units eliminate the risk of running out of stored hot water, tend to last longer than tank models, and are more energy efficient because they do not maintain standby temperature. The right choice depends on household size, simultaneous hot water demand, and fuel type availability.

Should a water heater be flushed annually?

Annual flushing is a standard maintenance recommendation for traditional tank water heaters in most regions. It removes accumulated sediment from the bottom of the tank, which improves heating efficiency and reduces the strain on the element or burner. In areas with harder water, flushing may be warranted more frequently. A plumber performing a water heater inspection can assess the sediment level and advise on an appropriate maintenance schedule.

Does Propane Work During a Power Outage?

Propane appliances are incredibly reliable, but will you still be able to use them when a storm comes through Greensboro and knocks out power? This is a common question with a somewhat complex answer.

The short answer: it depends on the appliance. Many propane appliances will continue to work when the power is out, including propane-powered cooking, water heaters, and backup heating equipment. However, you won’t be able to use a propane furnace, a boiler, or other appliances that use electric controls or ignition systems.

Greensboro, High Point, Winston-Salem, Burlington, and Eden see their share of extended outages. Summer thunderstorms, remnants of Atlantic tropical systems pushing inland, and winter ice storms can leave neighborhoods without power for hours or, in severe cases, several days. Knowing in advance which appliances you can count on, and which ones will be offline, is exactly the kind of preparation that makes a difference when the lights go out.

Berico has been serving home comfort customers throughout the region since 1924. Below is a complete guide to how propane performs during an outage, which appliances work and why, important safety considerations, and how to make sure you are never left without heat, hot water, or cooking capability during the next storm.

Which Propane Appliances Work During a Power Outage?

Whether a propane appliance works during a power outage depends entirely on whether it requires electricity to ignite or operate its controls. Appliances with standing pilot lights or manual ignition work without power. Appliances with electronic controls, electric ignition, or powered blower motors do not.

The table below covers the most common propane appliances found in Greensboro-area homes.

Appliance Works Without Power? Why
Propane range / cooktop burners Yes (manual light) Can be ignited manually with a match or lighter; gas flows without electricity
Propane water heater (standing pilot) Yes Pilot light stays lit; heats water continuously without electrical input
Propane fireplace (standing pilot) Yes Pilot light maintains ignition; no electrical components needed to operate
Propane gas logs (standing pilot) Yes Same as fireplace with standing pilot; no fan or control board required
Propane furnace No Requires control board, blower motor, and electronic ignition; all need power
Propane boiler No Electronic controls and circulation pumps require electrical power
Propane oven No Oven igniter and safety valve are electrically controlled; burners may work manually
Propane water heater (electronic ignition) No Electronic ignition cannot fire without power; no standing pilot to maintain flame
Propane standby generator Yes Designed specifically to produce power; restores electricity to the whole home

Why Do Some Propane Appliances Work Without Power and Others Don’t?

Appliances that can be lit manually or maintain a continuous standing pilot flame work during a power outage because propane gas can flow through the supply line without any electrical input. The distinction comes down to two factors: how the appliance ignites and whether it requires any electrically powered components to operate safely.

Appliances that can be lit manually tend to work when the power is out. The propane gas can flow in the absence of electricity, but if the appliance relies on an electric ignition, it won’t be able to get started. Ranges are a great example. If you have a propane range, you can turn on a burner and ignite it manually rather than using the standard electric igniter.

You can also use appliances that have a standing pilot light that is always ignited. Propane water heaters tend to work this way. Since the pilot light is already on when the power goes out, it can keep heating water even when the grid is not supplying your home with electricity. The same goes for a propane fireplace with a standing pilot light.

It’s when no pilot light is in place, or when other electrical components are required for the appliance to operate, that it won’t be able to run. Propane furnaces are the primary example of this situation. Yes, the propane is still available, but the furnace needs the control board and blower motor to work properly, along with the electric ignition system. Those parts won’t be working without electricity, so the furnace won’t work.

A Note from a Berico Fuel Delivery Specialist

“One thing we see regularly after a major storm in the Greensboro area is customers who assume their propane furnace will keep them warm during an outage, and then realize it won’t when they need it most. The propane is there, the tank is full, but the furnace can’t fire without the control board. Our best advice is to identify one propane appliance in your home that will work without power, usually a fireplace or a gas log set, and make sure you have that as your backup plan before storm season starts.” — Darrel Honeycutt, Fuel Delivery Specialist, Berico

Important Safety Considerations When Using Propane During a Power Outage

Using propane appliances safely during a power outage requires following a few basic rules, particularly around ventilation, carbon monoxide awareness, and not using appliances in ways they were not designed for.

Safety Reminders

  • Never use a propane range or cooktop as a heat source for your home. Cooking appliances are not designed for space heating and can produce dangerous levels of carbon monoxide in an enclosed space.
  • Make sure your home has working carbon monoxide detectors on every level, and test them before storm season.
  • If you smell gas at any point during or after a storm, do not attempt to use any appliance. Leave the home and call Berico or your local gas utility immediately.
  • Propane fireplaces and gas logs that require a blower fan for heat distribution will lose that fan function during an outage, but will still produce radiant heat without it.
  • Check your propane tank level before storm season, not after the outage has started. A delivery during an active storm may not be possible.

How to Stay Prepared for a Power Outage as a Propane Customer

The best preparation for a power outage happens before the storm arrives, not during it. Knowing which appliances work, confirming your tank level, and having a plan for heat and cooking will keep your household comfortable through most outages Greensboro, High Point, and Burlington can produce.

It’s a good idea to know in advance what appliances in your home are going to work during a power outage and which won’t be available. You might even want to make a quick list so you know what you can count on and what you’ll have to do without for the duration of the outage. For instance, if you can use your cooktop but not the inside of the stove, you can plan on making meals that only require using the range’s burners. Or, if you know that the furnace won’t work but the propane fireplace will, count on keeping the living room warm and spending most of your time there.

Pre-storm checklist for propane customers:

  • Check your tank level. Don’t wait until an outage is imminent. Berico offers automatic delivery through its propane delivery program, which monitors your usage and schedules deliveries before you run low.
  • Know how to manually light your cooktop burners. Keep a long-handled lighter or matches in an accessible location in the kitchen.
  • Identify your outage-safe appliances. Walk through your home and note which appliances have standing pilots and which rely on electronic ignition. Write it down if it helps.
  • Test your carbon monoxide detectors. Replace batteries before storm season, not after a power outage has already started.
  • Know Berico’s emergency contact number. Greensboro: (336) 273-8663. Berico provides service around the clock, every day of the year.

What About Propane Tank Levels During an Extended Outage?

During an extended outage, propane consumption increases significantly if you are relying on a gas fireplace or cooking appliances more heavily than usual. Monitoring your tank level and planning ahead with your propane supplier is the most reliable way to avoid running out during a multi-day event.

Berico offers Greensboro propane delivery as well as delivery to High Point, Burlington, Winston-Salem, Eden, and surrounding communities. For customers who want to eliminate the guesswork, Berico’s automatic delivery program tracks your usage based on weather data and usage history and schedules refills before you reach a critical level. This is particularly valuable during extended cold-weather outages when propane consumption spikes.

If you are unsure of your current tank level, check the gauge on the exterior of the tank before a storm is forecast. Most residential tanks have a float gauge on top that shows the approximate percentage remaining. As a general rule, scheduling a delivery when the tank reaches 20 to 30 percent is advisable, especially heading into storm season.

If your tank itself is aging or needs to be replaced, Berico handles propane tank replacement throughout the Greensboro area. An older tank with a compromised valve or fitting is not something to ignore heading into a season of heavy use.

The Best Long-Term Solution: A Propane Generator

A propane-powered whole home generator is the most effective solution for households that want to eliminate the limitations of a power outage entirely. Unlike portable gasoline generators, a standby propane generator connects directly to your home’s propane supply and activates automatically when the grid goes down, restoring power to your entire home within seconds.

If you don’t want to concern yourself with power outages moving forward, consider installing a propane generator to have an alternative power source when the grid goes down. With a standby generator in place, your propane furnace, your water heater’s electronic ignition, your refrigerator, and your lights all function normally during an outage. The appliance limitations described throughout this article simply stop being a concern.

Key facts about propane standby generators:

  • Automatic operation. A standby generator detects a power outage and starts automatically, typically within 10 to 30 seconds. There is no manual startup required.
  • Connected to your existing propane supply. The generator draws from the same tank that serves your home’s other appliances, so there is no separate fuel storage to manage.
  • Whole-home capability. Unlike portable generators, a properly sized standby unit can power your HVAC system, kitchen appliances, medical equipment, and all essential circuits simultaneously.
  • Requires professional installation. A licensed electrician installs an automatic transfer switch that safely disconnects your home from the utility grid before the generator powers on. This protects both your home and utility workers.

Berico installs Generac whole home generators and can help you select the right unit for your home’s load requirements. The Berico team handles the full installation, including the transfer switch, propane line connection, and any electrical work required. Because Berico also provides licensed electrical services, the entire project is handled under one roof.

Putting It All Together

Propane is one of the most resilient home energy sources available to homeowners in Greensboro, High Point, Burlington, and Eden. With the right preparation, a power outage becomes a manageable inconvenience rather than a crisis. Know your appliances, keep your tank level monitored, have a safety plan in place, and consider a propane generator if reliable backup power is a priority for your household.

Berico can help with this and many other types of projects, including propane tank replacement, Greensboro propane delivery, generator installation, and more. With such a great reputation throughout the region, know that you are in good hands anytime you reach out to the Berico team. Berico has been a trusted home comfort provider in this community since 1924, and we are here whenever you need us.

People Also Ask

Common questions from homeowners in Greensboro, High Point, Burlington, and Eden researching propane and power outage preparedness.

Will my propane furnace work if the power goes out?

No. A propane furnace requires electricity to operate its control board, blower motor, and electronic ignition system. Even though propane gas is available at the tank, the furnace cannot fire or distribute heat without power. A propane fireplace with a standing pilot light is the best backup heating option in this situation.

Can I use my propane stove during a power outage?

The burners on a propane range can typically be lit manually with a match or lighter during a power outage, since the gas flows without electricity. The oven, however, uses an electrically controlled igniter and safety valve and will not work without power. Do not use the cooktop as a heat source for the home, as this creates a carbon monoxide risk in an enclosed space.

How long will my propane tank last during a power outage?

Consumption depends on which appliances you are using and how frequently. A propane fireplace running several hours per day will draw down a tank meaningfully over a multi-day outage. Check your tank gauge before a storm is forecast, and contact Berico for a delivery if you are below 20 to 30 percent capacity.

Does a propane water heater work without electricity?

It depends on the model. Propane water heaters with a standing pilot light will continue heating water during a power outage because the pilot maintains a continuous flame without electrical input. Water heaters with electronic ignition will not work without power because the igniter cannot fire.

What is the difference between a standby propane generator and a portable generator?

A standby propane generator is permanently installed, connects directly to your home’s propane supply, and starts automatically when power is lost. A portable generator must be started manually, runs on gasoline or other fuel stored separately, and is typically used to power individual appliances rather than the whole home. Standby generators provide a more complete and hands-free solution for extended outages.

Is it safe to use a propane fireplace during a power outage?

Yes, a propane fireplace with a standing pilot light is generally safe to use during a power outage, provided the room is adequately ventilated, and carbon monoxide detectors are installed and functioning. The fireplace will produce radiant heat normally. If the unit has an electric blower fan, that fan will be inactive during the outage, but the heat output from the burner is not affected.

Can Storms Damage My HVAC System?

Yes, storms can damage HVAC equipment in a variety of ways, including physical damage from high winds and debris, electrical damage from lightning and power surges, and moisture damage from flooding or standing water near the outdoor unit.

As a resident of the Greensboro area, you are no stranger to powerful storms. The Triad sits in a weather corridor that delivers everything from fast-moving summer thunderstorms and remnants of Atlantic hurricanes to ice storms that can knock out power for days. With your HVAC equipment sitting right in the middle of these scary storms, is there any risk to your equipment?

Unfortunately, the answer is yes. Storms can damage HVAC equipment in a variety of ways. High winds and flying debris can damage outdoor components, lightning strikes can fry electrical components, and flooding can even impact the unit’s base and some internal parts. After a storm blows through, it’s worth at least taking a visual inspection of your system’s components to make sure everything looks okay.

Berico has been serving local homeowners since 1924, and storm-related HVAC calls are just some of the many service requests we receive after a major weather event. Below is a complete guide to what can go wrong, how to inspect your system safely, and what protective measures Greensboro homeowners should have in place before the next storm season.

What Types of Storm Damage Can Affect an HVAC System?

Storms can damage an HVAC system in three primary ways: physical damage from wind and debris, electrical damage from lightning strikes or power surges, and moisture intrusion from flooding or rain accumulation near the outdoor unit.

Every storm that hits the Greensboro area is different, and each brings its own risks. You’ll always hope that your HVAC system will make it through without suffering any damage, but the issues below are encountered by area homeowners each year.

Wind and Debris Damage

The outdoor unit of your HVAC system typically doesn’t have any protection from the elements and is at risk of damage from flying branches or other debris. In the aftermath of a storm, walk around the unit and look for signs of damage like crushed fins, visible dents, or objects lodged in the housing.

The aluminum fins on the outdoor coil are especially vulnerable. These thin metal fins direct airflow across the refrigerant coil, and even moderate bending can restrict airflow enough to reduce system efficiency or trigger pressure faults. A technician can use a fin comb to straighten minor fin damage, but significant crushing typically requires coil replacement.

What to look for after a windstorm:

  • Bent or crushed fins on the outdoor condenser coil
  • Visible dents in the sheet metal housing
  • Branches, gravel, or debris lodged inside the unit or against the coil
  • Disconnected refrigerant lines or electrical conduit
  • A unit that has shifted off its pad or mounting base

Flooding and Standing Water

Your outdoor condenser unit is certainly designed to handle rainfall, but standing water is another story. If the unit is partially submerged during the storm, water could have made its way in to damage electrical components, capacitors, or the motor.

The electrical components inside an outdoor condenser, including the capacitor, contactor, and wiring, are not waterproof beyond ordinary rain exposure. If water reaches these components, corrosion can develop over days or weeks, causing intermittent failures that are difficult to diagnose without a full inspection.

Do not attempt to run your HVAC system if you suspect flooding has reached the outdoor unit. Turn the system off at the thermostat and disconnect power at the disconnect box near the unit. Then call a licensed technician before restarting.

Lightning and Power Surges

If there is a lightning strike nearby, a rush of power can go through the electrical system and potentially damage the control board and compressor. If your system won’t start at all in the aftermath of a storm, electrical damage may be to blame.

A nearby lightning strike doesn’t have to hit your home directly to cause damage. A strike to a utility line or transformer several blocks away can travel through the power grid and enter your home as a high-voltage spike. Modern HVAC control boards are highly sensitive to electrical fluctuations, and even a brief overvoltage event can render the board non-functional.

The compressor is the most expensive component in your HVAC system. A surge that reaches the compressor motor windings can cause immediate failure or degrade the winding insulation over time, leading to a failure weeks or months after the storm. This is why post-storm inspection matters even when the system appears to be working normally.

A Note from a Berico HVAC Technician

“After a significant storm in the Greensboro area, the most common call we receive is from homeowners whose systems won’t start at all. Nine times out of ten, it’s a failed capacitor or a blown control board from the surge. The second most common issue is bent condenser fins from debris, which the homeowner often doesn’t notice until the system starts short-cycling or running longer than usual. We always recommend a post-storm inspection, even if the system seems to be running fine, because some damage is gradual.” — Darrel Honeycutt, HVAC Technician, Berico

Should I Run My HVAC System After a Storm?

You should not run your HVAC system immediately after a major storm if there is visible physical damage, standing water near the outdoor unit, or if the power was out during the storm and came back on with a notable flicker or spike. Allow the system to stabilize and perform a visual inspection first.

If none of those conditions apply and the system starts and runs without unusual sounds or odors, it is generally safe to operate. However, a professional post-storm inspection is the only way to confirm there is no hidden damage to the electrical components or refrigerant circuit.

Safe post-storm restart checklist:

  • Visually inspect the outdoor unit for debris, dents, and fin damage before powering on
  • Check that the unit is still level and seated properly on its pad
  • Look for any signs of water intrusion or corrosion around the electrical disconnect
  • Listen for unusual sounds during the first 10–15 minutes of operation
  • Check your thermostat display for any error codes or fault messages
  • If anything seems abnormal, shut the system down and call a technician

How Does a Whole House Surge Protector Protect My HVAC System?

A whole house surge protector is installed at your electrical panel and intercepts dangerous voltage spikes before they can reach your HVAC system, appliances, or electronics. It protects the compressor, control board, and electrical components that are most vulnerable to surge damage.

While you can’t do anything to stop the storms from arriving, you may want to consider investing in a whole house surge protector in Greensboro to add an important layer of defense. While the surge protector won’t help regarding the threats of flying debris or flooding, it can go a long way toward saving your equipment in the case of a power surge.

Here is how the device works in practice: a whole house surge protector is wired directly into your electrical panel. When a voltage spike occurs, whether from a lightning strike, a utility switching event, or a power restoration surge, the device detects the excess voltage and diverts it safely to ground before it can travel through your home’s wiring. The response time is measured in nanoseconds.

Key things to know about whole house surge protection:

  • Panel-level protection: Unlike plug-in surge strips, a whole house device protects every circuit in your home simultaneously, including hardwired equipment like your HVAC system that cannot use a plug-in protector.
  • It protects more than your HVAC: The nice thing about investing in a whole house surge protector is that it will protect more than just your HVAC equipment. It will stand in front of everything that is connected to your electrical system, including your appliances, electronics, and more.
  • Joule rating matters: Surge protectors are rated by how much energy they can absorb, measured in joules. A whole house device installed at the panel is rated to handle the high-energy events that plug-in strips cannot.
  • It works alongside GFCI and breakers: Surge protection, GFCI outlets, and circuit breakers serve different functions. Breakers protect against overcurrent. GFCI outlets protect against ground faults. Surge protectors protect against voltage spikes. A properly protected home needs all three.

Adding this component to your home is a smart investment that will be worth far more than its cost. Berico’s licensed electricians handle whole house surge protector installation throughout Greensboro, High Point, Burlington, and surrounding Triad communities.

What Else Should Triad Homeowners Do to Protect Their HVAC System Before Storm Season?

Beyond surge protection, Greensboro homeowners can take several steps before storm season to reduce the risk of HVAC damage from high winds, flooding, and power events.

The Triad’s storm season runs from late spring through early fall, with the highest risk period typically falling between June and September when Atlantic tropical systems can push inland and merge with frontal boundaries to produce extended periods of heavy rain, gusty winds, and lightning.

  • Schedule a pre-season HVAC maintenance visit. A Berico technician will inspect the electrical components, check refrigerant charge, and confirm the system is in good condition before the most demanding months of the year. Berico’s HVAC maintenance plans are designed for exactly this purpose.
  • Clear the area around your outdoor unit. Trim back shrubs, remove gravel or loose material, and make sure there are no branches that could fall on the unit during a storm. Maintain at least 18 to 24 inches of clearance on all sides.
  • Know where your disconnect is. The outdoor disconnect box is typically mounted on the wall near the outdoor unit. Knowing how to cut power to the system quickly can prevent damage if you need to act fast during a storm.
  • Consider a whole house generator. Extended power outages after major storms can be hard on HVAC systems when power is restored suddenly. Berico installs Generac whole home generators, which provide seamless backup power and eliminate the surge risk that comes with utility power restoration.
  • Check your electrical panel. If your home has an older panel, it may be less effective at handling modern electrical loads and more susceptible to surge damage. Berico’s licensed electricians can assess your panel and recommend upgrades if needed.

What Should I Do If a Storm Damages My HVAC System?

If you suspect storm damage to your HVAC system, the first step is to disconnect power at the outdoor disconnect and at the breaker, perform a visual inspection without touching any electrical components, and call a licensed HVAC technician before attempting to restart the system.

If you need HVAC repair work performed after a storm harms your system, calling Berico is the best choice.

People Also Ask

Common questions from Greensboro-area homeowners researching storm damage and HVAC protection.

Can a power surge from a storm destroy my air conditioner?

Yes. A large power surge from a nearby lightning strike or utility event can damage or destroy an HVAC system’s control board, capacitor, and, in severe cases, the compressor motor. These components are sensitive to overvoltage and may fail immediately or develop intermittent issues in the weeks following the surge.

How do I know if my HVAC was damaged by a lightning strike?

Common signs of lightning or surge damage include: the system won’t start at all after the storm, the thermostat is unresponsive or displaying error codes, the outdoor unit hums but the fan or compressor doesn’t engage, or circuit breakers for the HVAC system have tripped. A licensed technician can perform a component-level diagnosis to identify exactly what failed.

Can an air conditioner get damaged by flooding?

Yes. While outdoor condenser units are built to withstand rain, standing water that submerges the unit can reach internal electrical components, including the capacitor, contactor, and motor windings. Do not restart a unit that has been submerged until a technician has inspected and cleared it.

Does homeowner’s insurance cover storm damage to an HVAC system?

Storm damage to HVAC equipment caused by a covered peril, such as a lightning strike or wind-driven debris, is typically covered under a standard homeowner’s insurance policy. Flood damage may require separate flood insurance. Surge damage is sometimes covered, but depends on the policy language. Contact your insurance provider to confirm your coverage before filing a claim.

Does a whole house surge protector protect my HVAC system?

Yes. Because your HVAC system is hardwired into your electrical panel rather than plugged into an outlet, plug-in surge strips cannot protect it. A whole house surge protector installed at the panel intercepts voltage spikes before they can reach any circuit in the home, including the HVAC system. This is one of the most effective steps a Greensboro homeowner can take to protect HVAC equipment from storm-related electrical damage.

How often should I have my HVAC system inspected after a storm?

Any time a major storm passes through, including storms that produce lightning, high winds, or flooding, it is a good practice to have a technician inspect your system. At minimum, a visual inspection by the homeowner should be performed after every significant storm, with a professional inspection scheduled if anything appears damaged or if the system is behaving differently than normal.
