5 Signs You Need Professional Sewer Line Cleaning in Greensboro

/in /by

The five most reliable signs that you need professional sewer line cleaning are repeated drain backups, slow drains throughout the house, sewer odors, gurgling plumbing sounds, and wet or unusually green patches in the yard. When was the last time you thought about your sewer line? It has probably been a while, if you are like most homeowners. However, Greensboro sewer line cleaning is important, and these five signs indicate that the time is now for this job.

Greensboro’s older housing stock is one reason this topic matters more here than in newer markets. Homes built before 1970 in neighborhoods like Fisher Park, College Hill, Sunset Hills, Latham Park, Westerwood, and Irving Park are the most likely candidates for clay or cast-iron sewer lines and the problems that come with them. Both materials are more susceptible to root intrusion, scale buildup, and cracking than modern PVC. A sewer line that has been in the ground for 40 or 50 years may show these warning signs even before any visible failure occurs.

Watch for These Five Signs That Sewer Line Cleaning Is Required

Professional sewer line cleaning may be required at your Greensboro property if any of the five signs below are present, particularly if more than one symptom is occurring at the same time, which points to a main line restriction rather than a localized clog.

Professional sewer line cleaning may be required at your property if any of the five signs below are spotted.

  • Repeated drain backups. This is one of the big warning signs that you have trouble with your sewer line. If you have already cleared a drain, such as one serving your sink or toilet, and it quickly backs up again, the problem may be with the main sewer line instead. A drain snake can clear a local clog, but if the restriction is further down the main line, the backup will return within days. Repeated clearing of the same drain without a lasting result is the clearest indicator that the problem is beyond the fixture level.
  • Slow drains everywhere. One slow drain is likely the result of a local clog, but consistently slow draining throughout the house is often a sign that something is restricting flow in the sewer line. When multiple fixtures, such as the kitchen sink, bathroom sink, and shower, are all draining slowly at the same time, the common point of restriction is the main sewer line. A partial blockage from grease accumulation or early-stage root growth can reduce the line’s interior diameter enough to slow everything without causing a complete backup.
  • Unpleasant sewer odors. Have you noticed unwanted smells coming up from your drains? That could point to waste buildup or a sewer line blockage. Also, in the case of a broken sewer line, you might also notice this unpleasant smell outside near the yard. Sewer gas contains hydrogen sulfide, which produces the characteristic rotten egg odor. When a blockage prevents proper venting of the plumbing system, or when a cracked line releases gas into the soil, that odor makes its way into the home or yard. Odors outside the home near the yard are particularly significant, as they may indicate a crack or break in the line below grade rather than a simple interior buildup.
  • Gurgling plumbing sounds. If you hear gurgling noises when water drains, that might point to air that is trapped and struggling to move through a blocked sewer line. The gurgling sound occurs because water flowing past a partial blockage displaces air, and that air is forced back up through the nearest fixture trap. A toilet that gurgles when the washing machine drains, or a sink that makes noise when the dishwasher empties, is a reliable indicator that the main sewer line is partially restricted.
  • Wet spots in the yard. When there is a leak in your sewer line, you’ll often find that the moisture leads to a soft, wet spot in the yard, or even an extra-green patch of grass due to the additional water available under the surface. The nitrogen and nutrients in sewage act as fertilizer, which is why the grass above a leaking line is often noticeably greener and more vigorous than the surrounding lawn. A soft, spongy area of yard that has not been saturated by rain, or a consistently greener strip of grass following the path of the sewer line toward the street, are both signs that warrant a camera inspection.

Why Tree Root Intrusion Is a Particular Risk in Greensboro

Tree root intrusion is one of the most common causes of sewer line problems in Greensboro because the city’s mature urban tree canopy means root systems are extensive and widespread, and older clay and cast-iron sewer lines offer less resistance to root penetration than modern PVC pipe.

Tree roots naturally seek moisture, and the small amounts of water vapor that escape from the joints of older sewer pipes are enough to attract them. Once a root finds an entry point, it grows inside the pipe, catches debris, and progressively narrows the interior until flow is severely restricted. This process happens slowly, which is why the five warning signs above often develop gradually over months rather than appearing overnight.

The wet spots and extra-green grass sign is especially relevant for root intrusion. When roots have created enough of a blockage to cause pressure buildup inside the line, water eventually finds its way out through cracks or joints and saturates the surrounding soil. By the time a homeowner notices soft ground or unusually green grass above the sewer line’s path, the root mass inside the pipe may already be substantial.

“In Greensboro, we see root intrusion on almost every camera inspection we run in neighborhoods with older clay or cast-iron lines. The homeowner usually comes to us because a drain is slow or backing up, and they assume it’s a simple clog. When we put the camera in the line, we find roots that have been growing for years. The five signs in this article are exactly what those situations look like from inside the house, and they are telling you something that a drain snake alone is not going to fix.”

Adam Rhodes, Expert Plumber, Berico

What Is the Difference Between Drain Cleaning and Sewer Line Cleaning?

Drain cleaning addresses clogs in the individual branch lines that serve specific fixtures such as sinks, toilets, and showers, while sewer line cleaning addresses the main line that carries all of the home’s wastewater from the house to the municipal connection at the street.

A blocked drain at a single fixture, such as a slow bathroom sink, is a branch-line problem that can usually be resolved with a drain snake or localized cleaning. When multiple fixtures are affected simultaneously, or when the same drain keeps backing up after being cleared, the problem is in the main sewer line and requires a different approach.

Berico’s professional sewer line cleaning service uses advanced equipment to clear the main line of debris, grease, tree roots, and stubborn blockages. The service can also include video camera inspection, which confirms that the cleaning is complete and identifies any structural issues inside the pipe, such as cracks or collapsed sections, that cleaning alone cannot address. Drain cleaning for individual fixtures is a separate service that Berico also provides for Greensboro homeowners dealing with localized clogs.

How Video Camera Inspection Changes the Diagnosis

Video camera inspection allows Berico’s plumbers to see exactly what is inside a sewer line in real time, eliminating guesswork about the cause and location of a blockage and confirming whether the issue is buildup, root intrusion, a structural crack, or a collapsed section of pipe.

Before camera inspection became standard, diagnosing a sewer line problem meant making educated guesses based on symptoms. A plumber might snake the line, clear an apparent blockage, and consider the job done. If the real problem was a root mass two-thirds of the way down the line, the clog would return within weeks. Camera inspection reveals exactly what is in the pipe and where, which means the right solution can be applied the first time.

For Greensboro homeowners with older clay or cast-iron lines, camera inspection also reveals the structural condition of the pipe itself. A line that can be cleaned and maintained is a very different situation from one that has cracked, shifted, or partially collapsed and requires repair or replacement. Knowing which category your line falls into before work begins saves time and prevents surprises.

Sewer Problems Get Worse Over Time

Sewer line problems almost never resolve on their own and will worsen progressively over time, with what begins as minor slowdowns eventually developing into complete backups, pipe damage, and sewage intrusion into the home if left unaddressed.

It’s common for sewer line issues to gradually get worse over time. Rarely, if ever, do they resolve themselves. In many cases, buildup gradually accumulates inside the pipe until wastewater can no longer flow properly. Things like grease, debris, soap residue, and tree roots can all contribute to blockages in your sewer line.

As the restriction in the line grows, the pressure inside your plumbing system will build. This is usually first seen as minor slowdowns in draining. Eventually, it can cause backups and even pipe damage that is extremely costly and time-consuming to resolve. Your best course of action is to have routine sewer line cleaning completed before something catastrophic occurs, and you wind up facing a bigger and more expensive problem. Professional plumbers can use advanced tools and techniques to effectively and safely clean out your sewer line.

Should You Have Your Sewer Line Cleaned Preventively?

Routine preventive sewer line cleaning is particularly valuable for Greensboro homes with older clay or cast-iron pipes or significant tree coverage, as it removes accumulating buildup before it reaches the point where the five warning signs above begin to appear.

Berico offers a plumbing maintenance plan that includes sewer line inspection as one of its service components. For homeowners who have experienced sewer problems in the past, or who know their home sits on an older clay or cast-iron line with trees nearby, a preventive cleaning and inspection on a regular schedule is a practical way to stay ahead of the problem rather than responding to it after the warning signs have already appeared.

The cost and inconvenience of a scheduled cleaning is far less than the cost of a sewage backup into the home, the water damage that can follow, and the emergency service call required to address it after the fact.

Frequently Asked Questions About Sewer Line Cleaning in Greensboro

How often should you have your sewer line cleaned?

For most homes, a professional sewer line inspection and cleaning every 18 to 24 months is a reasonable preventive schedule. Homes with known tree root issues, older clay or cast-iron pipes, or a history of repeated backups may benefit from more frequent service. Berico’s plumbing maintenance plan includes sewer line inspection as part of its regular service schedule.

What is the difference between drain cleaning and sewer line cleaning?

Drain cleaning addresses clogs in individual fixture branch lines, such as a slow sink or backed-up tub. Sewer line cleaning addresses the main line that carries all wastewater from the home to the street connection. If only one drain is affected, the problem is likely a branch-line clog. If multiple drains are slow or backing up simultaneously, the main sewer line is the more likely culprit.

Can you clean a sewer line yourself?

Consumer-grade drain snakes can clear simple clogs near the drain opening, but they are not effective for main sewer line cleaning, root intrusion, or heavy grease buildup deeper in the line. Professional sewer line cleaning uses equipment capable of reaching the full length of the main line. Camera inspection before and after the cleaning confirms what was cleared and whether any structural issues need attention.

What happens during a professional sewer line cleaning?

A Berico plumber will typically begin with a video camera inspection to identify the location and nature of the blockage. Based on those findings, the appropriate cleaning method is selected to clear the line. After cleaning, a second camera pass confirms that the line is clear and identifies any structural issues, such as cracks, root entry points, or collapsed sections that may require repair.

Why Is My AC So Loud All of a Sudden?

/in /by

An air conditioner that suddenly gets louder is almost always reacting to a mechanical problem: loose or failing components, debris in the outdoor unit, a worn fan motor, refrigerant issues, or a struggling compressor. The specific sound your AC is making is the most useful clue about which problem you are dealing with. Did your air conditioner recently get much louder with no obvious explanation? This particle will help you understand what might be going on so you can describe it clearly when you call for HVAC repair.

Greensboro’s long cooling season, running from late spring through September, puts sustained demands on AC systems that accelerate normal component wear. High humidity levels also create conditions that affect electrical contacts, capacitors, and fan motor bearings faster than drier climates. When a system that has been quietly doing its job suddenly announces itself with a new noise, the cause is usually something that has been developing over time and finally reached the point where it cannot be ignored.

What Causes Loud Air Conditioning?

An air conditioner may suddenly become loud due to a number of reasons, from debris in the outside unit to a failing compressor. Unusual noises are often a sign that parts are vibrating or otherwise struggling, and these warning signs should not be ignored.

One of the tricky things about dealing with a noisy air conditioner is that the problem can stem from many different places. The sound itself is your best diagnostic tool. A rattling noise points to something different than a hissing noise, and a banging noise requires a different response than a buzzing noise. The sections below break down what each type of sound typically indicates and how urgent the response should be.

AC Making a Rattling or Clanking Noise

A rattling or clanking noise from an AC unit typically indicates loose panels, debris caught in the outdoor condenser, or a failing component that has come loose from its mount and is contacting other parts as the system runs.

  • Loose panels. Over time, panels or other internal components can shake loose and start to vibrate loudly as the system is running. The screws and fasteners that hold the cabinet together can work themselves loose over seasons of use, especially on older systems.
  • Debris in the outdoor unit. If leaves, sticks, or other pieces of debris get into your outdoor condenser, they will interfere with the fan blades. Since those blades spin so fast, the noise created can be quite alarming. Greensboro’s spring pollen season and fall leaf drop are the two periods when debris-related noise calls are most common.

A rattling that transitions into a hard clanking sound is more serious. Clanking typically means a component has fully come loose inside the unit and is striking the housing or other parts with each rotation. Turn the system off if you hear hard clanking and call for service before running it again, as continued operation can cause additional damage.

AC Making a Grinding or Screeching Noise

A grinding or screeching noise from an AC unit usually indicates a failing fan motor, worn bearings, or a belt-driven component that has deteriorated, and these sounds require prompt attention because they typically worsen quickly and can lead to complete motor failure.

  • Worn fan motor or blades. You might notice a loud grinding or buzzing noise if you are having trouble with the fan motor or the blades themselves. Fan motor bearings dry out over time, and when they do, the metal-on-metal friction produces a grinding or screeching that gets progressively louder with each use cycle.

A failing capacitor can also produce a grinding or struggling sound as the fan motor tries to start under load without proper electrical support. The capacitor is a small cylindrical component inside the outdoor unit that provides the startup voltage boost the fan motor and compressor need. Capacitor failure is one of the most common service calls during Greensboro’s summer months, when high temperatures stress these components most. Screeching sounds should be treated as urgent: continued operation risks burning out the motor entirely, which is a significantly more expensive repair than replacing a capacitor or motor bearing.

AC Making a Hissing or Bubbling Noise

A hissing or bubbling noise from an AC unit is most commonly caused by a refrigerant leak, where escaping refrigerant gas produces a hissing sound at the leak point or a bubbling sound if air has entered the refrigerant line.

  • Refrigerant issues. When the problem stems from the refrigerant, there might be a hissing or bubbling sound coming from the system. Refrigerant does not deplete naturally: a hissing sound is a signal that there is a leak in the refrigerant circuit, not just a low charge that can be topped off.

A refrigerant leak also reduces cooling efficiency, causes the compressor to work harder, and can eventually freeze the evaporator coil. If you hear a hissing sound and notice that the home is not cooling as well as it normally does, both symptoms together make a refrigerant leak the most likely diagnosis. This is not a DIY repair. Refrigerant handling requires EPA certification, and the leak must be located and repaired before the system is recharged. Berico’s HVAC technicians are trained in refrigerant replacement and leak repair as part of their full AC repair service.

AC Making a Banging Noise

A banging noise from an AC unit is one of the more serious sounds the system can make, usually indicating a loose or broken component inside the compressor or a severely unbalanced blower assembly that is striking the housing with each rotation.

  • Compressor problems. The compressor is a critical component in any air conditioner. If it is starting to fail, it might create a loud vibrating noise that is impossible to ignore. A banging sound specifically from the outdoor unit often points to something loose inside the compressor itself, such as a broken connecting rod, piston pin, or compressor mount.

A banging noise warrants an immediate system shutdown. Running a compressor with a broken internal component can cause catastrophic failure of the entire compressor, which is one of the most expensive single-component repairs in an HVAC system. Turn the system off, switch to fans if available, and call for service. Do not reset and restart the system to see if the noise goes away.

“In Greensboro, we see a pattern every summer where homeowners hear a new noise in June, assume it will go away, and call us in August when the system has completely failed. The noise is almost always telling you something specific. A hiss points to refrigerant. A grind points to a motor or bearing. A bang means stop the system right now. The earlier we get a look at it, the better the odds that it is a repair rather than a replacement.”

Karim Gourari, HVAC Technician, Berico

AC Making a Buzzing Noise

A buzzing noise from an AC unit can indicate electrical issues such as a failing contactor or capacitor, loose wiring, a refrigerant leak causing pressure irregularities, or debris vibrating against the fan assembly inside the outdoor condenser cabinet.

Electrical buzzing at the outdoor unit is often traced to the contactor, a relay switch that opens and closes to send power to the compressor and fan motor. Contactors wear over time, and a buzzing contactor may be on the verge of failing to close properly, which would prevent the compressor from starting at all. Electrical buzzing should always be evaluated by a licensed technician since the causes range from a simple debris issue to a wiring problem that poses a safety risk.

Why These Noise Changes Are So Important

A sudden increase in AC noise almost always signals that a component is failing or under abnormal stress, and continuing to run the system without investigation risks turning a manageable repair into a complete system failure that could have been prevented.

Your AC unit is always going to make some noise as it runs, but that noise should be modest and predictable. If it suddenly gets particularly loud, something has changed and a complete breakdown may not be far behind. It’s tempting to just ignore these noises, but that would be a mistake. Instead, your best bet is to take a closer look and make sure nothing is seriously wrong before continuing to use the air conditioner.

A Few Simple Checks Before Getting Help

Before calling for service, you can check for visible debris around and inside the outdoor condenser unit, listen to determine whether the noise is coming from the indoor or outdoor unit, and watch for visible vibration, which helps your technician narrow the diagnosis quickly when they arrive.

Most of the time, AC fixes need to be left to the professionals. However, there are a few things you can check on your own, starting with looking for debris near the outdoor unit. You can also listen to see if the noise is coming from inside or outside your home, and you can watch as it runs to see if you notice visible signs of vibration. All of this information will be helpful when you call to make an appointment, as you can give the technician direction as they start their inspection.

One additional check: make sure the outdoor unit is sitting level on its pad and that no vegetation has grown up around it. A unit that has settled unevenly can produce vibration noises that have nothing to do with internal component failure. Greensboro’s summer growth season means shrubs and grasses can encroach on a condenser quickly, and restricted airflow around the cabinet stresses the fan motor and compressor even before noise becomes obvious.

When to Turn Your AC Off Immediately

Turn your AC off immediately and call for service if you hear banging, hard clanking, or screeching sounds, if you smell burning or detect a burning smell near the indoor unit or outdoor condenser, or if the noise began suddenly at full volume rather than gradually increasing over time.

These scenarios indicate that continuing to run the system risks additional damage. Banging and clanking mean something is loose and striking other components. Screeching means a motor or bearing is failing under friction. A burning smell means an electrical component or motor winding is overheating. In each case, the cost of the repair increases with every additional hour the system runs. Berico offers 24-hour emergency AC service for Greensboro homeowners who need a same-day response.

Frequently Asked Questions About a Loud AC

Is it safe to run my AC if it is making a loud noise?

It depends on the sound. A mild rattling or buzzing may be safe to run briefly while you schedule a service call, but banging, hard clanking, screeching, or any noise accompanied by a burning smell warrants an immediate shutdown. Continuing to run a system with a broken internal component or failing motor can cause additional damage that significantly increases the repair cost.

Why did my AC suddenly get louder overnight?

A sudden overnight noise increase is typically caused by debris entering the outdoor unit, a component that finally failed after a period of gradual wear, or a capacitor or contactor that gave out during the previous cooling cycle. Greensboro’s summer storms can drive leaves and debris into the condenser cabinet overnight. Check for visible debris first, and if the unit is clear, call for a diagnostic visit.

What does a hissing AC sound mean?

A hissing sound from an AC unit most commonly indicates a refrigerant leak, where pressurized refrigerant gas is escaping from a crack or failed joint in the refrigerant line. A hissing sound paired with reduced cooling output and higher energy bills is a strong indicator of a leak. Refrigerant repair requires a licensed HVAC technician and cannot be addressed with a DIY recharge.

Can a noisy AC fix itself?

No. Mechanical and electrical issues that cause AC noise do not resolve on their own. Loose components get looser, worn bearings deteriorate further, and refrigerant leaks continue to lose pressure. A noise that seems to go away often means the component has failed completely rather than recovered. Early diagnosis is always less expensive than waiting for a complete breakdown.

Why Do My Circuit Breakers Keep Tripping?

/in /by


Circuit breakers keep tripping due to overloaded circuits, short circuits, ground faults, faulty appliances, arc faults, or a breaker that has simply worn out and can no longer hold its rated load reliably. Circuit breakers play a critical safety role in electrical systems. If they keep tripping in your home, Greensbor electrical repair may be needed to resolve the problem.

Common Reasons for Circuit Breakers to Trip

It’s normal to have a circuit breaker trip occasionally, but if you have regular issues with your breakers, a bigger problem is likely at play.

Most residential circuits in Greensboro homes are rated at either 15 amps or 20 amps for general-purpose circuits, with higher-amperage dedicated circuits for appliances like electric dryers, water heaters, and HVAC equipment. When the total draw on a circuit exceeds its rated capacity, the breaker trips to prevent the wiring from overheating. Understanding which type of problem is causing the trip is the first step toward the right fix.

Which Problem Is Leading to Your Tripped Breakers?

Identifying which cause is tripping your circuit breakers requires evaluating whether the trip happens under heavy load, immediately upon reset, gradually over time, or only when a specific appliance is running on the affected circuit.

The correct fix for breakers that keep tripping depends on the underlying cause of the problem. Consider the following possibilities:

  • Overloaded circuits. When too many devices are drawing power from the same circuit, that circuit will become overloaded and may trip. The fundamental purpose of breakers is to cut power in this scenario to prevent overheating. A standard 15-amp circuit can safely carry about 1,440 watts of continuous load. Running multiple high-draw devices on the same circuit, such as a space heater, hair dryer, and microwave, will frequently push past that threshold.
  • Short circuits. When a hot wire touches a neutral wire, a short circuit occurs. This leads to a sudden surge of electricity, and again, the breaker will trip for safety purposes. Short circuits happen when wire insulation deteriorates, connections loosen with age, or wiring is damaged by pests or physical impact. The breaker often trips immediately and may produce a burning smell or a popping sound at the panel.
  • Ground faults. This is similar to a short circuit, but a little different. In this case, electricity strays from its intended path, perhaps due to moisture exposure or damaged wiring. Ground faults are particularly common in kitchens, bathrooms, garages, and outdoor areas where moisture is present, which is why GFCI protection is required in those locations under current NC electrical code.
  • Arc faults. An arc fault occurs when electricity jumps across a gap in damaged, loose, or deteriorating wiring, generating intense heat that can ignite surrounding materials inside a wall cavity before any visible sign of a problem appears. Arc faults are one of the leading causes of residential electrical fires. Modern AFCI breakers are designed to detect and interrupt arc faults, and they are required under the 2023 NEC for most living areas in new and renovated construction.
  • Faulty appliances. If you have a malfunctioning appliance, it could draw too much power and cause the breaker to trip over and over again. Unplugging the suspected appliance and resetting the breaker is a quick test. If the breaker holds without the appliance connected, the appliance itself is the problem.
  • A failing or worn-out breaker. Circuit breakers are mechanical devices with a finite service life. A breaker that trips repeatedly with no apparent overload, short circuit, or fault may simply be worn out. Breakers in older Greensboro homes can become weakened over decades of use and may trip at loads well below their rated capacity. This is one of the most common scenarios that leads to a circuit breaker replacement rather than a repair of the underlying circuit.

What Greensboro Homeowners Should Know About Older Electrical Systems

Older Greensboro homes face a higher risk of recurring breaker trips because many were built with 100-amp panels that are undersized for modern electrical loads, and homes built between 1965 and 1973 may contain aluminum branch-circuit wiring that loosens over time and creates intermittent faults.

A 100-amp panel was considered adequate when it was installed in homes built decades ago. Modern households run significantly more electrical load: multiple refrigerators, large HVAC systems, EV chargers, home office equipment, and high-draw kitchen appliances. An undersized panel that is consistently running near capacity will produce chronic tripping even without a specific fault in any individual circuit. Panel capacity, not just individual circuit issues, is often the root cause.

Aluminum wiring, which was used in a significant number of Greensboro homes constructed during a period when copper prices were high, expands and contracts at a different rate than the copper connections it terminates on. Over time, those connections loosen. Loose connections at outlets, switches, and the panel create resistance, generate heat, and can cause both ground faults and arc faults that trip breakers repeatedly. If your home was built during that period and you are having recurring electrical problems, aluminum wiring should be part of the diagnostic conversation with your electrician.

“In Greensboro, the most common thing we find on a chronic tripping call is a 100-amp panel in a home that now has twice the electrical load it was designed for. The second most common thing is a breaker that tests fine on paper but trips at 12 amps on a 15-amp circuit because it’s been doing that job for 40 years. Both of those situations look like circuit problems from the outside, but the real fix is the panel, not the wiring.”

Toni Mortera, Electrician, Berico

When Should You Immediately Call an Electrician?

Call an electrician immediately if a tripped breaker is accompanied by a burning smell, warm or discolored outlet covers, sparking at the panel, a breaker that will not reset, or any breaker that trips instantly the moment it is reset to the on position.

These symptoms indicate that the problem has moved beyond a simple overload into potentially dangerous territory. A breaker that trips instantly on reset usually means a short circuit or ground fault is still present in the wiring, and restoring power to that circuit before the fault is located and repaired creates a fire and shock risk. Berico offers 24-hour emergency electrical service for Greensboro homeowners facing these situations.

Other scenarios that warrant an immediate call rather than troubleshooting on your own:

  • Multiple breakers tripping at the same time, which can indicate a problem at the main panel rather than individual circuits
  • A breaker that feels hot to the touch at the panel
  • Buzzing or crackling sounds coming from the panel or from outlets on the affected circuit
  • Any visible scorching or discoloration on breakers, wiring, or the panel interior
  • Breakers tripping in a home with known aluminum wiring

Don’t Ignore This Ongoing Problem

Recurring breaker trips are a warning signal from your electrical system that should be diagnosed and resolved, not managed by resetting and moving on, because the underlying cause will worsen over time and increase the risk of wiring damage or electrical fire.

It’s easy to reset a breaker after it has been tripped. As a result, you might be tempted to just ignore the problem and move on. You can quickly reset the breaker after it trips and go on with your day. That’s fine if it only happens once in a while, but if it happens often, there is a problem that should be addressed. Some underlying cause is tripping the breaker, so you would be smart to pay attention to that warning sign and dig deeper to see how it can be fixed correctly.

Take These Steps Before Getting Help

Before calling a professional, you can take a few basic steps to determine whether the trip is caused by a simple overload, which is the most common and easily resolved cause of a tripped breaker in a home. First, unplug a few devices from the affected circuit and see if that makes a difference. You may simply be overloading the circuit by asking it to supply too much power in too many directions. Also, you can break up high-powered devices on multiple circuits if they need to run at the same time. If these basic adjustments don’t solve the problem, it’s likely not an overload issue, and you’ll need to get professional help.

Frequently Asked Questions About Tripping Circuit Breakers

Is it dangerous if a circuit breaker keeps tripping?

It can be. A breaker that trips occasionally due to a temporary overload is doing its job correctly. A breaker that trips repeatedly, trips on reset, or trips with no apparent cause may indicate a short circuit, ground fault, arc fault, or a failing breaker, all of which require professional diagnosis. Continuing to reset a breaker without finding the cause increases the risk of wiring damage or electrical fire.

How do I know if I need a new circuit breaker or a new panel?

A single breaker that trips repeatedly under normal load, feels hot, or will not hold its position after reset typically needs to be replaced. If multiple breakers are tripping, if the panel is undersized for your home’s current electrical load, or if the panel is more than 25 to 30 years old, a full panel evaluation is warranted. Berico’s licensed electricians can test individual breakers and assess overall panel capacity to determine the right solution.

Can a bad appliance cause a breaker to keep tripping?

Yes. A malfunctioning appliance that draws more current than its rated load will trip the breaker on the circuit it is connected to. Unplug the suspected appliance and reset the breaker. If the breaker holds without the appliance connected, the appliance is the source of the problem. An appliance with a damaged heating element, failing motor, or short in its power cord can cause repeated trips even when nothing else is on the circuit.

How long do circuit breakers last?

Most circuit breakers have a service life of 30 to 40 years under normal conditions, though breakers in older homes may degrade faster due to heat cycling, corrosion, or frequent trips over decades of use. A breaker that is tripping at loads well below its rated capacity is likely nearing the end of its useful life and should be tested and replaced by a licensed electrician.

Why Do You Need a Whole House Surge Protector in North Carolina?

/in , /by

You need a whole house surge protector in Greensboro because the region experiences frequent storms, lightning activity, and grid fluctuations that send damaging voltage spikes into homes, and because everyday internal surges from appliances cycling on and off quietly degrade electronics and HVAC equipment over time. Using a surge protector to cover your whole house is a smart step toward protecting electronics, appliances, and more.

According to Berico’s own electrical team, homes in the Greensboro area experience 14 to 16 power surges every single day. Most of those surges are modest enough that you never notice them, but their cumulative effect on sensitive electronics, HVAC components, and major appliances is real and measurable. A whole house surge protector installed at the main electrical panel intercepts those surges before they reach any of your home’s circuits.

What Does a Whole House Surge Protector Actually Do?

A whole house surge protector is a device installed at your main electrical panel that detects incoming voltage spikes and diverts the excess energy to ground before it can travel through your home’s branch circuits and damage connected equipment.

Your home is protected from sudden voltage spikes when you have a quality whole house surge protector installed. These voltage spikes can come from a variety of causes, including lightning, power grid fluctuations, large appliances turning on and off, and more.

The installation process involves a licensed electrician mounting the surge protection device directly at the main panel, connecting it between the incoming utility power feed and your home’s circuits. This placement is what makes whole-house protection fundamentally different from a power strip. A strip only protects what is plugged directly into it. A panel-mounted device protects every outlet, appliance, and circuit in the entire home simultaneously.

Residential whole house surge protectors are rated in joules, which measures how much surge energy the device can absorb before it needs to be replaced. Quality systems for Greensboro homes are typically rated between 50,000 and 140,000 joules. Higher joule ratings indicate greater capacity to handle more severe events. Berico’s electricians also evaluate the kA (kiloampere) rating of a device, which measures how much surge current it can handle in a single event. A higher kA rating means the device can withstand the intense current spike from a nearby lightning strike without being overwhelmed. Most quality units also include indicator lights that alert you when the device has absorbed significant surges and needs attention.

Why Does Greensboro Have So Many Power Surges?

Greensboro and the surrounding Triad area experience a high frequency of power surges because the region sits in one of the most lightning-active corridors of the eastern U.S., and its extensive above-ground utility infrastructure is vulnerable to storm-related grid disruptions that send voltage spikes into connected homes.

If you have lived in North Carolina for a while, you already know that powerful storms are common in this part of the world. Sure, there are plenty of beautiful sunny days, but when storms roll through, you want to make sure your house is protected and prepared.

During these storms, fluctuations in the power grid are common. Those fluctuations can come from trees falling on power lines, lightning strikes, and more. If the activity from a storm sends a rush of electricity through the grid and into your home, all of your various appliances and electrical devices could be at risk.

Greensboro’s spring and summer storm season runs from roughly April through September, with thunderstorm activity peaking in the summer months. The city’s location in the Piedmont Triad puts it in the path of storm systems that develop over the Appalachians and track east, as well as tropical systems that push inland from the coast. That combination makes above-average surge exposure a year-round reality rather than a seasonal concern.

What Are Overloaded Circuits and How Do They Relate to Surges?

Overloaded circuits occur when the total electrical demand placed on a single circuit exceeds its rated capacity, which can cause breakers to trip, wiring to overheat, and voltage irregularities that stress connected devices in the same way that external surges do.

An overloaded circuit is not the same as a power surge, but the two problems are related. When a circuit is consistently running near or at its capacity limit, the voltage fluctuations that occur as loads cycle on and off are more pronounced. Those fluctuations are a form of internal surge. In older Greensboro homes with electrical panels that were sized for a smaller number of appliances and devices than are in use today, overloaded circuits are a common finding during electrical inspections.

Addressing overloaded circuits, either by redistributing loads, adding circuits, or upgrading the panel, reduces the internal surge activity that whole house protection alone cannot fully counteract. Berico’s licensed electricians can assess panel capacity and circuit loading as part of an electrical evaluation.

Why Whole House Surge Protection Is Worth the Investment

Whole house surge protection is worth the investment because voltage spikes, whether from storms, grid switching, or internal appliance cycles, cause both immediate equipment damage and long-term cumulative degradation that shortens the lifespan of electronics, appliances, and HVAC systems.

You might think that power surges are rare, but that’s not quite the case. In fact, modest power surges happen often, even in calm conditions. Having surge protection in place is valuable for a number of reasons:

  • Safeguard electronic devices. You likely rely on these devices for countless purposes each day, including things like TVs, computers, gaming systems, smart devices, and more. These items are particularly at risk of surge damage if they aren’t protected.
  • Prevent appliance damage. You can also experience costly damage to things like refrigerators, HVAC systems, and washing machines when a surge comes through. Even the accumulation of small surges over time can lead to problems.
  • Stop internal surges. Did you know that not all surges come from the grid? A burst of power can occur when large appliances cycle on and off, and that surge can harm other devices.

Why Your HVAC System Is Especially at Risk from Power Surges

Modern HVAC systems are among the most surge-vulnerable equipment in a home because they contain variable-speed compressors, electronic control boards, and programmable thermostats that cannot tolerate the voltage spikes that older mechanically controlled equipment could survive.

The compressor in a central air conditioning system is one of the largest electrical loads in the home, and it is also one of the most common sources of internal surges. Each time a compressor cycles on, it draws a brief spike of current that travels back through the electrical system. Without protection, that spike reaches every other device on the circuit. With a panel-mounted whole house surge protector in place, that energy is diverted before it can cause harm.

The cost of HVAC surge damage puts the investment in protection into perspective. Replacing a damaged variable-speed heat pump or air handler can cost thousands of dollars. Whole house surge protection installation represents a fraction of that expense and protects not just the HVAC system but every appliance and electronic device in the home at the same time. As Berico’s team notes, a whole house surge protector is specifically recommended to protect HVAC systems, well pumps, air purifiers, computers, televisions, and other sensitive equipment throughout the home.

“In Greensboro, we see surge-related HVAC damage most often after the first major storm of the season, when a nearby lightning strike sends energy through the grid and into control boards that were already being stressed by daily internal surges. What I always tell homeowners is that the panel-mounted device and the surge strip work together. The whole house unit handles the big events at the entry point, and the strip gives the most sensitive electronics a second layer of defense. Neither one alone gives you the full picture.”

Toni Mortera, Electrician, Berico

Does a Whole House Surge Protector Work Against Lightning?

A whole house surge protector provides meaningful protection against the voltage spikes that travel through the electrical system from nearby lightning strikes, but it is not designed to absorb the full energy of a direct lightning strike to the home or its utility service entrance.

Lightning is a different category of event than a standard power surge. A direct strike contains far more energy than any residential surge protective device is rated to handle. However, most lightning-related surge damage does not come from a direct strike to the home. It comes from strikes to nearby trees, utility poles, or the ground that inject energy into the grid and send it toward connected homes. In those scenarios, a whole house surge protector can intercept and divert the surge effectively.

For homeowners concerned about direct lightning risk, a lightning rod system can be added to direct strike energy safely into the ground. That is a separate system from surge protection and addresses a separate threat. The two can work together as complementary layers of protection.

Pair Your Whole House Surge Protector with Point-of-Use Protection

Whole home surge protection works best when you pair it with point-of-use protection tools like standard surge strips. This combination gives you a layered approach to protecting against surges and keeping your things safe. So, even if you have a whole house surge protector in use, it’s still smart to plug in things like computers and other electronics into a surge strip first.

As Berico’s electrical team notes, whole house surge protection is strongly recommended, and a surge protection strip for in-home electronics is also advised because sensitive devices like computers and televisions are particularly vulnerable to even small voltage variations that a panel-mounted device may not fully eliminate. The combination of both layers is the most complete approach available to a homeowner.

Frequently Asked Questions About Whole House Surge Protection

Does a whole house surge protector really work?

Yes. A whole house surge protector installed at the main electrical panel intercepts voltage spikes before they enter any branch circuit in the home. It is more comprehensive than individual power strips because it protects every outlet, appliance, and hardwired device simultaneously. For maximum protection, pair the panel-mounted device with surge strips for sensitive electronics like computers and televisions.

What is the difference between a whole house surge protector and a power strip?

A whole house surge protector is installed at the main electrical panel and protects every circuit in the home from surges entering through the utility service. A power strip only protects devices plugged directly into it and provides no protection for hardwired appliances, HVAC systems, or outlets elsewhere in the home. The two work best used together as complementary layers of protection.

How many joules do I need for whole house surge protection?

Residential whole house surge protectors are typically rated between 50,000 and 140,000 joules. Higher joule ratings indicate a greater capacity to absorb severe surge events before the device needs to be replaced. A licensed electrician can recommend the appropriate rating based on your home’s equipment, location, and exposure to storm activity.

Does homeowners insurance cover surge damage?

Some homeowners insurance policies cover surge damage caused by lightning strikes, but coverage for other types of surges, such as grid fluctuations or internal appliance surges, varies widely by policy. Review your policy details with your insurance provider. Regardless of coverage, whole house surge protection is a proactive investment that prevents damage from occurring rather than compensating for it afterward.

Why Does My Drain Keep Backing Up?

/in /by

Drains back up repeatedly due to clogs, the accumulation of buildup inside the pipes, tree root intrusion, sewer line issues, or improper drainage design. A single clog is a pretty easy issue to fix, but repeated backups point to a problem that should be addressed by a professional plumber.

Plumbing problems are always frustrating, and backed-up drains are near the top of the list. There are a few common reasons you might deal with this ongoing issue, and understanding which one applies to your home is the first step toward a lasting fix.

Common Causes of Backed-Up Drains

The most common causes of recurring drain backups are grease and debris buildup, hair and soap scum accumulation, foreign objects in the drain, tree root intrusion into sewer lines, and deteriorating or misaligned pipes that restrict flow.

You don’t need to be a plumber to at least consider more carefully what it is that is causing your drain to back up. This is important because you might be able to resolve the issue yourself, depending on what is going on. Of course, for more serious matters such as sewer line repair in Greensboro, you’ll need to turn to the Berico team for help.

Here are the most common culprits to investigate when your drain keeps backing up:

  • Grease and debris buildup. Over time, your kitchen drain will accumulate grease and food particles that will gradually narrow the pipe and slow down the flow of water. This buildup will need to be cleared before the pipe flows freely again.
  • Hair and soap scum. In a bathroom setting, it’s often hair and soap scum that cause narrowing of the pipes. Just as in the kitchen, it’s necessary to clear these blockages in order to restore proper function.
  • Foreign objects in the drain. Things that aren’t supposed to go down the drain, such as paper towels, wipes, and other hygiene products, can quickly lead to a complete blockage.
  • Tree root intrusion. Tree roots naturally seek out water sources, and the small amounts of moisture that escape from sewer pipe joints are enough to attract them. Once a root finds its way into a pipe, it grows and branches inside the line, catching debris and progressively restricting flow until backups occur.
  • Deteriorating or misaligned pipes. In older Greensboro homes, sewer lines were often made of clay or cast iron. Clay pipes can crack and shift as soil moves. Cast iron corrodes over time. Either condition creates rough interior surfaces that catch debris and cause recurring backups even after the line is cleared.

Why Tree Root Intrusion Is Especially Common in Greensboro

Tree root intrusion is one of the most common causes of recurring sewer line backups in Greensboro because the city’s mature tree canopy means root systems are extensive, and underground sewer pipes, particularly older ones, are frequently within reach of those roots.

Greensboro is fortunate to have a rich urban tree canopy, but what happens underground is a different story. Tree roots can wrap around and even grow through vulnerable pipes. Sewer lines made of clay, which were standard in homes built through much of the mid-twentieth century, are particularly susceptible because the joints between sections allow moisture to escape, which draws roots directly to the pipe.

A drain that backs up repeatedly, is slow across multiple fixtures at the same time, or produces gurgling sounds from toilets and sinks after water is used elsewhere in the house is displaying the classic signs of root intrusion in the main sewer line. This is not a problem that a plunger or a store-bought drain cleaner will resolve. It requires professional equipment to clear and a camera inspection to confirm the scope of the damage.

“In Greensboro, we use a camera to inspect the line on almost every recurring backup call. What looks like a simple clog at the fixture level is frequently a root mass halfway down the sewer line. Once we can see what we’re dealing with, we can choose the right tool for the job, whether that’s a mechanical clearing or a repair if the pipe itself has cracked. Skipping the inspection and just snaking the line is how those calls become repeat calls.”

Adam Rhodes, Berico Plumbing Pro

Warning Signs That the Problem Is in Your Main Sewer Line

A main sewer line problem is indicated when multiple drains back up at the same time, toilets gurgle when other fixtures are used, sewage odors appear in or around the home, or wet or sunken patches develop in the yard above the sewer line’s path.

Individual drain clogs affect one fixture. A sewer line problem affects the whole system. The distinction matters because the solutions are different. If your kitchen sink backs up but everything else drains normally, the clog is likely in the branch line serving that sink. If your toilet gurgles when you run the washing machine, or if water backs up into the tub when you flush, the problem is further down in the main line.

Other warning signs of a main sewer line issue include foul sewage odors coming from drains or from the yard, patches of unusually green or wet grass over the sewer line’s path to the street, and a drain that clears briefly after snaking but backs up again within days. Any of these signs warrants a camera inspection before more snaking is attempted.

Why Recurring Drain Issues Should Get Your Attention

Recurring drain backups that keep returning after clearing are a sign that the underlying cause has not been fully addressed, and delaying a proper diagnosis allows the problem to worsen, potentially leading to pipe damage, sewage backups into the home, or costly sewer line repairs.

When you notice that the same drain continues to get clogged over and over, that should serve as a warning sign that something has gone wrong and it’s not being fully fixed. Even if you partially clear the drain to let it flow for a while, the fact that the backup keeps returning speaks to a lingering problem. Getting a plumber to fully complete the fix is the best way, in most cases, to leave these struggles in the past.

Why Chemical Drain Cleaners Make the Problem Worse

Chemical drain cleaners contain caustic acids that can damage PVC pipes and accelerate corrosion in older metal plumbing, making them a short-term fix that often worsens the underlying pipe condition and contributes to future leaks and backups.

The temporary relief that a chemical cleaner provides is real, but so is the damage it does over repeated use. In older Greensboro homes with cast-iron or galvanized steel drain lines, the caustic chemistry in liquid drain cleaners speeds up the interior corrosion that is already occurring naturally with age. In homes with PVC pipes, the heat generated by some chemical reactions can soften joints and fittings. Neither outcome helps with the recurring backup problem, and both make future repairs more complicated.

A mechanical approach, using a drain snake for simple clogs or professional sewer line cleaning for more stubborn buildup, addresses the blockage without attacking the pipe itself. For the same reason, Berico’s plumbers avoid recommending chemical cleaners as a maintenance solution even when they appear to work temporarily.

Try a Few DIY Solutions

While it will often be necessary to reach out to the plumbers at Berico for help, there are a few things you can try on your own.

  • Use a plunger to dislodge the blockage in the drain
  • Try a drain snake to pull out hair or other debris
  • Run hot water to help break up grease buildup in the kitchen sink
  • Remember to avoid the use of chemical cleaners, as they may do significant damage to your pipes over time

These steps are appropriate for a single, isolated backup that has not recurred before. If the drain backs up again within a few weeks of being cleared by these methods, or if multiple drains are slow at the same time, the problem has moved beyond DIY territory, and a licensed plumber should evaluate the system.

Frequently Asked Questions About Recurring Drain Backups

Why does my drain back up again right after I just cleaned it?

A drain that backs up quickly after being cleared usually means the root cause was not fully addressed. Snaking a drain removes an immediate blockage but leaves grease coating, soap scum buildup, or root debris on the pipe walls. Those residuals continue to accumulate and create the next backup. Professional sewer line cleaning or a camera inspection can identify and resolve the underlying issue.

Can tree roots cause my drain to back up?

Yes. Tree root intrusion is one of the most common causes of recurring sewer line backups, especially in homes with older clay or cast-iron sewer lines. Roots enter through pipe joints, grow inside the line, and catch debris until the line is partially or fully blocked. Camera inspection is the only reliable way to confirm root intrusion and assess the extent of the damage.

Are chemical drain cleaners safe to use regularly?

No. While chemical drain cleaners can provide temporary relief, repeated use damages both PVC and metal pipes from the inside. They corrode cast-iron and galvanized lines faster and can soften PVC joints over time. A mechanical solution, such as a drain snake or a professional cleaning for more serious buildup, is safer for the long-term health of your pipes.

How do I know if the problem is in the sewer line or just a single drain?

If only one drain is slow or backing up and all others work normally, the clog is likely in the branch line serving that fixture. If multiple drains are slow, if toilets gurgle when other water is running, or if sewage odors are present, the problem is in the main sewer line. A camera inspection can pinpoint exactly where the blockage or damage is located.

Why Is My AC Bill So High This Spring?

/in /by

Your AC bill is likely high due to reduced system efficiency, dirty components, incorrect thermostat settings, refrigerant issues, duct leakage, or aging equipment working harder than it should to maintain comfortable temperatures. Air conditioning can keep your family comfortable all spring and summer long in Greensboro, but when the bill spikes unexpectedly, one or more of these causes is almost always responsible.

Spring in Greensboro brings a specific challenge for AC systems. Temperatures swing from cool mornings to humid afternoons, and systems that sat idle through a mild winter are suddenly asked to run for extended periods. If that system was not serviced before the cooling season began, the first month of heavy use is often where efficiency losses show up on the utility bill.

Reasons for Rising Air Conditioning Bills

Your AC bill may be high this spring due to any of the reasons mentioned above, and you should explore all of these possibilities more closely to figure out which of these problems is affecting you.Ā  However, beyond the more common of these causes, two culprits account for a significant share of unexplained efficiency losses in Greensboro homes: low refrigerant from a slow leak, and duct leakage that sends conditioned air into unconditioned spaces like attics and crawl spaces. Both can drive up operating costs substantially without any obvious sign that something is wrong with the equipment itself.

How to Know What’s Causing Higher AC Bills

Identifying the cause of a high AC bill requires checking filters, coils, thermostat settings, system age, refrigerant charge, and duct integrity, either through your own inspection of accessible components or by scheduling a diagnostic visit with a licensed technician.

It takes a bit of critical thinking and taking a closer look at your system to understand why your rates are rising. You can start this process on your own, or you can just call Berico now for prompt air conditioning service. Here are the most common culprits to investigate when there is a problem with a high bill associated with your AC:

  • Dirty air filters. If your air filter is dirty, the air conditioner is going to have to run longer to keep your home at a comfortable temperature. And, of course, if it runs longer, it is going to use more energy and cost you more month after month.
  • Dirty coils. As dust and debris accumulate on the coils, they lose some of their ability to transfer heat while the AC runs. Again, this is an issue that is going to lead to higher energy consumption.
  • Thermostat settings. Have you set your home a little cooler than it used to be set? Even changing the setting by just a couple of degrees can increase your bill by a surprising amount.
  • Aging equipment. There is no way around this one. As your air conditioner ages, the parts are going to inevitably wear, and the whole system won’t work as efficiently as it did years ago.
  • Low refrigerant. Refrigerant does not deplete naturally. If your system is running low, it means there is a leak somewhere in the refrigerant circuit. A low charge forces the compressor to work harder and run longer to achieve the same cooling output, which drives up energy use even though the system appears to be working normally.
  • Duct leakage. In many Greensboro homes, conditioned air leaks out of gaps, joints, and unsealed connections in the duct system before it ever reaches the living space. The Department of Energy estimates that duct leakage accounts for 20 to 30 percent of total cooling loss in a typical home. If your ducts run through an unconditioned attic or crawl space, that loss is happening in some of the hottest parts of your home.
  • Utility rate changes. Sometimes the bill goes up even when the system has not changed. Duke Energy and other providers adjust rates seasonally and annually. Checking your rate schedule can confirm whether a portion of the increase is on the utility side rather than the equipment side.

What Is a SEER Rating and Why Does It Affect Your Bill?

SEER, which stands for Seasonal Energy Efficiency Ratio, measures how efficiently an air conditioner converts electricity into cooling over an entire season, and a higher SEER rating means lower operating costs for the same amount of cooling output.

The minimum SEER rating for new AC equipment sold in the Southeast, including North Carolina, is currently 15 SEER2 for central air systems. Older systems commonly have SEER ratings of 8 to 10. An aging 10-SEER system uses roughly 50 percent more electricity to produce the same cooling as a modern 20-SEER unit. Over a full Greensboro summer, that gap translates directly into higher monthly bills.

SEER ratings also degrade over time as components wear. A system that was rated 14 SEER when it was installed may be operating at an effective efficiency of 10 to 11 SEER after a decade of use without regular maintenance. This is one of the reasons that annual tune-ups matter: keeping the system clean, properly charged, and mechanically sound preserves as much of that original efficiency as possible.

How Does Low Refrigerant Raise Your Energy Bill?

Low refrigerant reduces an AC system’s ability to absorb heat from indoor air, causing the compressor to run longer cycles trying to reach the set temperature, which consumes significantly more electricity without delivering any additional cooling.

A refrigerant leak is rarely dramatic. There is no obvious noise or failure. The system continues to run, but the cooling output gradually declines. The compressor compensates by running longer, and the bill climbs while the home feels slightly less comfortable than it used to. By the time a homeowner notices a problem, the compressor may have been under stress for weeks or months.

Refrigerant cannot simply be “topped off.” Regulations require that any leak be located and repaired before the system is recharged. Berico’s technicians are equipped to pressure-test the system, locate the source of the leak, and restore the refrigerant charge to the manufacturer’s specification.

“In spring, we see a lot of systems in Greensboro where the refrigerant charge dropped over the winter from a slow leak. The system runs, the house cools eventually, but the compressor is working overtime to get there. The homeowner’s first sign is usually the utility bill. By the time we test the system in April or May, the charge might be 10 to 15 percent low. Catching that in a spring tune-up is exactly the kind of thing that saves a compressor and brings the bill back down.”

Josh Longley, HVAC Technician, Berico

Does Duct Leakage Really Make That Much Difference?

Yes. Duct leakage is one of the most underdiagnosed causes of high cooling bills, and in homes where ducts run through attics or crawl spaces, losing 20 to 30 percent of conditioned air before it reaches living areas is common and measurable.

In Greensboro, attic temperatures regularly exceed 130 degrees Fahrenheit during summer afternoons. When a duct with a leaking joint passes through that attic, the cold air inside it is simultaneously leaking out and absorbing heat from the surrounding space. The result is that the system works harder, the rooms do not cool as quickly, and the bill reflects the extra runtime without delivering the comfort the homeowner expects.

Duct sealing and insulation improvements can significantly reduce this loss. A professional energy audit can identify where leakage is occurring and quantify how much it is contributing to the overall efficiency problem. Berico offers free energy audits to help homeowners understand exactly where their cooling dollars are going.

Take Smart Steps to Lower Your Costs

The most effective steps to lower a high AC bill are replacing the air filter, scheduling a professional maintenance tune-up, checking thermostat settings, and having a technician evaluate the system for refrigerant charge and duct integrity.

The first step you can take to keep your energy costs under control is to change your air filter often. This is an affordable DIY task to complete every month or two, and making sure you always have a fresh filter in the system will give the air conditioner the opportunity to run efficiently.

You should also make it a point to have HVAC maintenance performed at least once per year. Don’t wait until something goes wrong with the system. Instead, stay ahead of the game by scheduling preventive maintenance. This will help you avoid breakdowns and keep things working as they should. Over the long run, consistent maintenance can slow down the aging process and give your AC unit the best possible chance to keep working well long into the future.

Berico’s 17-point AC maintenance plan covers the items most directly connected to energy efficiency: coil cleaning, refrigerant pressure check, blower inspection, capacitor testing, electrical connection verification, and filter replacement. A properly maintained system can reduce energy consumption by 15 to 20 percent compared to a neglected one. Berico’s Comfort and Protection Service Agreements make that annual maintenance easy to schedule and keep the system in top condition year-round.

Additional steps homeowners can take between professional visits:

  • Keep all supply and return vents open and unobstructed by furniture or drapes
  • Set the thermostat a few degrees higher when the home is empty for several hours
  • Use ceiling fans to improve air circulation and allow the thermostat to be set slightly higher
  • Keep the outdoor condenser unit clear of grass, debris, and overgrowth
  • Check that window and door seals are intact so cooled air is not escaping the living space

Frequently Asked Questions About High AC Bills

Does a dirty filter really raise my electric bill?

Yes. A clogged air filter restricts airflow across the evaporator coil, forcing the system to run longer cycles to move the same volume of air through the home. That extended runtime uses more electricity. Replacing the filter every one to two months is one of the simplest and most effective ways to keep operating costs down.

Why does my AC bill go up in spring even before the weather gets really hot?

Spring in Greensboro brings rising humidity levels well before peak summer heat arrives. AC systems remove humidity as part of the cooling process, and higher humidity means the system runs longer to maintain both temperature and comfort. A system that sat idle through winter and was not serviced before the cooling season is especially likely to show efficiency losses in those first months of use.

When should I replace my AC instead of repairing it?

A common guideline is the 5,000 rule: multiply the system’s age in years by the estimated repair cost. If the result exceeds 5,000, replacement is usually the better investment. A system older than 15 years with a SEER rating below 14 and recurring repair needs is generally a strong candidate for replacement with a more efficient modern unit.

What SEER rating should I look for in a new AC system in North Carolina?

The minimum efficiency for new central AC systems in the Southeast is currently 15 SEER2. For a home in Greensboro that runs the AC heavily from May through September, a system rated 18 SEER or higher will produce meaningful savings on monthly bills compared to a minimum-efficiency unit. Berico offers free replacement estimates and can help you evaluate the payback period on higher-efficiency equipment.

GFCI Outlet Requirements in North Carolina: Is Your Greensboro Home Up to Code?

/in /by

Professional electrician working on a home electrical system, he is installing a wall socket

North Carolina requires GFCI outlets in any area of a home where electricity and water are likely to come into contact, including kitchens, bathrooms, garages, basements, laundry areas, and outdoor spaces, under NEC Article 210.8. Staying compliant with electrical codes in North Carolina keeps your home safe. So, what do the Greensboro electrical code requirements say about GFCI outlets? Here’s what to know.

For Greensboro homeowners, this is not just a new-construction concern. Older homes throughout Guilford County that predate modern code cycles may be missing GFCI protection in one or more required locations. A licensed electrician can identify those gaps quickly and bring the home into compliance before a sale, renovation, or inspection surfaces the issue.

What Is a GFCI Outlet?

A GFCI outlet, which stands for Ground Fault Circuit Interrupter, is a specialized electrical outlet that monitors current flow in a circuit and shuts off power within milliseconds when it detects even a small imbalance caused by a ground fault. This imbalance can be from electricity flowing through water or even through a person.

The quick response of a GFCI outlet is why it is able to keep people safer around electricity. Shutting down the circuit so quickly can prevent serious electrical shocks and greatly reduce the likelihood of serious injury.

A standard breaker or fuse is designed to protect the wiring and equipment, not a person. It responds to overloads and short circuits, but that response time is far too slow to prevent electrocution. A GFCI outlet detects as little as 4 to 6 milliamps of current leakage and trips in as little as 1/40th of a second, a speed that is fast enough to interrupt a shock before it becomes lethal. That distinction is why building codes require GFCI outlets specifically in areas where moisture is present.

Why GFCI Outlets Are So Important

GFCI outlets are required in wet and damp areas because water dramatically lowers the body’s electrical resistance, making even a low-voltage shock potentially fatal without a fast-acting ground fault interrupter in place.

When you use a standard electrical outlet, power is going to continue to flow even if something dangerous is occurring. In some settings, where risks are low, that’s perfectly fine. For example, in your living room, the outlet where your TV is plugged in is probably off in a corner and rarely touched. Using standard outlets in such a setting is typical, and minimal risk is involved.

The story changes in settings where water is commonly present. Kitchens and bathrooms need GFCI outlets specifically because of the water that is used in these areas. Water greatly increases the risk of electrical shock, and the risk goes up even higher if children are often present. With a GFCI outlet, you’ll still want to keep water safely away from outlets, of course, but you’ll have extra peace of mind knowing that the circuit will shut down if it gets wet.

North Carolina summers add another dimension to this risk. High humidity levels throughout the Greensboro area, particularly from June through September, create elevated moisture conditions in garages, crawl spaces, and even finished rooms that affect how quickly outlets in damp zones can become hazardous. Properly installed GFCI protection in all code-required locations accounts for these conditions.

Where Are GFCI Outlets Required in North Carolina Homes?

Under NEC Article 210.8, which governs North Carolina’s electrical code for residential properties, GFCI protection is required in kitchens, bathrooms, garages, basements, laundry areas, outdoor receptacles, and within six feet of any sink.

North Carolina adopted the 2023 NEC (with state amendments) through the NC Building Code Council. The following locations in a dwelling unit require GFCI-protected outlets:

  • All receptacles serving kitchen countertop surfaces require GFCI protection. Under the 2023 NEC, this expanded to include all receptacles in the kitchen, not just those at the countertop level.
  • Any receptacle in a bathroom, regardless of how close it is to a water source, must be GFCI-protected.
  • Garages and accessory buildings. All outlets in attached and detached garages, as well as accessory buildings with floors at or below grade, require GFCI protection.
  • All outdoor receptacles on the exterior of the home require GFCI protection.
  • Unfinished and finished basements require GFCI protection for all receptacles.
  • Laundry areas. Receptacles in laundry rooms and laundry areas require GFCI protection under the 2023 NEC, reflecting an expanded code requirement from earlier editions.
  • Within six feet of any sink. Any outlet located within six feet of a sink, measured along the path a power cord would travel, requires GFCI protection regardless of which room it is in.
  • Receptacles in boathouses are also covered under the 2023 NEC expansion.

Many older homes in Greensboro were permitted and built under earlier code editions that had narrower GFCI requirements. A home built before the mid-1970s may have no GFCI outlets at all. A home built in the 1980s or 1990s may have them in bathrooms and kitchens, but not in the garage, laundry area, or basement. A licensed electrician can assess which locations are currently protected and which are not.

What Is the Difference Between a GFCI Outlet and a GFCI Breaker?

A GFCI outlet provides ground fault protection at a single receptacle location, while a GFCI breaker is installed in the electrical panel and protects every outlet on the entire circuit, making it an efficient option for areas with multiple required GFCI locations.

Both achieve the same protective goal. The choice between them depends on the layout of the home’s electrical system and how many outlets in a given area require protection. In a garage with four outlets, for example, a single GFCI breaker protecting the entire garage circuit may be more practical than installing individual GFCI outlets at each location. In a bathroom with one outlet, a single GFCI outlet is usually the simpler solution.

Older Greensboro homes that are having GFCI protection added after the fact often use GFCI breakers for areas like basements or garages where multiple unprotected outlets exist on a shared circuit. Your electrician will determine which approach is appropriate based on your home’s wiring configuration.

“In Greensboro, we regularly find homes where the kitchen and bathrooms have GFCI outlets, but the garage, basement, and laundry room were never updated. Those gaps are exactly what comes up during a home inspection or a permit pull for a renovation. The fix is usually straightforward, but it needs to be done by a licensed electrician so the work is permitted and inspected properly. Skipping the permit on electrical work like this is one of the most common things that slows down a home sale in this area.”

Toni Mortera, Electrician, Berico

What Is the Difference Between GFCI and AFCI Protection?

GFCI protection guards against ground faults, which occur when electricity travels an unintended path through water or a person, while AFCI protection guards against arc faults, which are dangerous electrical arcs in wiring that can ignite fires inside walls.

Both types of protection are required under North Carolina’s electrical code, and they address different hazards. GFCI protection is focused on shock prevention in wet areas. AFCI protection is focused on fire prevention in living spaces such as bedrooms, living rooms, dining rooms, and other areas where damaged or deteriorating wiring could create an arc fault inside a wall cavity before any visible sign of a problem appears.

The two requirements often overlap during renovation and rewiring projects. When a Greensboro homeowner is upgrading a kitchen, adding a basement outlet, or renovating a bathroom, the work may trigger both GFCI and AFCI compliance requirements, depending on what circuits are being modified. Berico’s licensed electricians are familiar with current Guilford County inspection requirements and can ensure that both types of protection are addressed correctly during any electrical project.

Check Your Home to See If It Meets Code Requirements

You don’t need to be a Greensboro electrician to check for GFCI outlets in your home. Look around at the outlets in areas like your kitchen and bathroom to see if they have “test” and “reset” buttons on the front. If they do, those are GFCI outlets. If not, you have regular outlets and should consider upgrading right away, though a full compliance assessment requires a licensed electrician to evaluate every required location in the home.

Keep in mind that a GFCI breaker at the panel will protect all outlets on that circuit without any individual outlet showing the test and reset buttons. If you are uncertain whether a specific outlet is GFCI-protected, a licensed electrician can trace the circuit and confirm its protection status. This is especially relevant in older Greensboro homes where circuit labeling in the panel may be incomplete or inaccurate.

Testing your existing GFCI outlets regularly is also good practice. Press the “test” button on the outlet face. The outlet should lose power immediately. Press “reset” to restore it. If the outlet does not respond correctly, it may be faulty and should be replaced. GFCI outlets have a service life and can fail over time, particularly in humid or outdoor environments.

Frequently Asked Questions About GFCI Outlets in North Carolina

Are GFCI outlets required in older homes in Greensboro, NC?

Existing older homes are not always required to retrofit GFCI outlets unless renovation or repair work triggers a code compliance review. However, adding GFCI protection to all required locations is strongly recommended for safety, and it is required for any new outlet installation or circuit modification under current NC electrical code.

What is the difference between a GFCI outlet and a regular outlet?

A regular outlet delivers continuous power without monitoring the circuit for imbalances. A GFCI outlet continuously monitors current flow and shuts off power within milliseconds if it detects a ground fault, which is electricity traveling an unintended path through water or a person. GFCI outlets have visible “test” and “reset” buttons on their face.

Can I install a GFCI outlet myself in North Carolina?

North Carolina law requires that electrical work, including outlet installation and replacement, be performed by a licensed electrician or under the supervision of one. Unpermitted electrical work can create safety hazards and create complications when selling a home or filing an insurance claim. Berico’s licensed electricians handle GFCI installation with the proper permits and inspections.

How do I know if my home’s GFCI outlets are working properly?

Press the “test” button on the face of any GFCI outlet. The outlet should immediately lose power. Press “reset” to restore power. If the outlet does not respond correctly to the test, it should be replaced. GFCI outlets in outdoor or high-humidity locations should be tested more frequently, as exposure to moisture can shorten their service life.

Is It Time to Replace My Water Heater?

/in /by

Modern water heaters are impressively reliable, but no piece of equipment lasts forever. Should you explore water heater repair or replace the whole unit? That question comes up more often than you might think, and the answer depends on several key factors: the age of your system, the nature of the problem, and how much life is realistically left in the unit.

For homeowners in Greensboro, Burlington, Eden and High Point, this decision can feel especially pressing during peak demand seasons. Cold winters and hot summers put constant strain on your water heater, and a unit that is already struggling will rarely get better on its own.

These Signs Indicate You Need a New Water Heater

You likely need to replace your water heater if it is more than 10 years old, requires frequent repairs, does not produce hot water consistently, or shows signs of leaks or corrosion. Minor issues can be repaired, but aging systems that run into many problems should simply be replaced.

Knowing which category your water heater falls into is not always obvious from the outside. Some problems develop slowly over months before becoming noticeable. Others appear suddenly, leaving you with cold showers and no clear explanation. The guide below covers the most common warning signs Berico plumbing technicians encounter in Triad-area homes.

A Closer Look at These Problems

Understanding what is going wrong with your water heater is the first step toward deciding whether or not to invest in a replacement. Here’s some additional info that should be helpful.

Age of the Unit

Most standard tank-style water heaters have a lifespan of 8 to 12 years, and a unit approaching or past that range should be evaluated carefully before investing in additional repairs. If your system is getting to that age, you can assume that you will need to purchase a replacement sometime soon.

You can find the manufacture date on the label attached to the tank, usually near the top. The first four characters of the serial number often encode the month and year. If you are unsure how to read it, a Berico plumbing technician can identify the age during a service visit.

Inconsistent Hot Water

When internal components start to fail in a water heater, you may notice that you run out of hot water faster than you used to, or that the temperature fluctuates up and down as you use it. In electric units, this is often caused by a failing heating element. In gas units, it can point to a deteriorating burner assembly or thermocouple.

If you have a larger home in neighborhoods like Irving Park or Lake Jeanette, inconsistent hot water that coincides with heavy household use could also be a capacity issue. Upgrading to a larger tank or switching to a tankless water heater could solve the problem permanently.

Unusual Noises

A water heater should be relatively quiet as it works. If you have started to hear unusual sounds like popping or rumbling, those can point to sediment buildup inside the tank. This is a common issue in the Triad, where mineral deposits accumulate over time.

Sediment settles at the bottom of the tank and gets superheated during each cycle. The popping or knocking sounds you hear are steam bubbles forcing their way through that layer. Beyond the noise, sediment reduces heating efficiency and accelerates wear on the tank liner. Flushing the tank annually can slow this process, but a unit with heavy buildup and existing age may be past the point where flushing helps.

Rusty or Discolored Water

Check the color of your hot water when it is running out of a tap. If you see a brown or reddish tint, you might have corrosion inside of the tank. This is a serious warning sign because once the interior of the tank has begun to corrode, no repair can fully reverse the damage.

Before concluding that the tank itself is the source, run cold water from the same tap. If the discoloration only appears in the hot water line, the tank is the likely culprit. If both lines are discolored, the issue may originate in your pipes. A Berico plumber can diagnose the exact source and give you an accurate assessment.

Visible Leaks or Moisture Around the Tank

Pooling water or persistent moisture near the base of your water heater is a sign that something has failed structurally and that replacement is likely the only long-term solution. Small drips from fittings or the pressure relief valve can sometimes be repaired. However, moisture coming from the tank body itself indicates that the tank has cracked or corroded through.

Even a slow leak should be treated urgently. Water heater failures can cause significant property damage if the tank lets go completely. If you spot pooling water, shut off the cold water supply to the unit and call Berico right away.

 

“In my experience working on water heaters in Greensboro and the surrounding Triad, the homeowners who wait too long on a replacement end up dealing with emergency calls and water damage that could have been avoided. If your unit is 10 years old and you are already paying for the second or third repair, the math rarely works out in your favor. A new, properly sized unit will perform better and cost less to operate from day one.”

The Repair vs. Replacement Debate

Not every hot water heater issue demands a complete replacement. Sometimes, your best bet is to just have a minor repair completed and move on. For instance, if you need a new heating element for a water heater that is less than 10 years old, going ahead with the repair will make a lot of sense.

When you start to think twice about repairs is when they are expensive and required on an older unit. Before moving forward with any repair, think about how much the repair will be in comparison to installing a new water heater. If you are approaching half or more of the cost of a new one, and the current one is already around the 8 to 10 year mark, repairs might not make financial sense. You can always speak with a member of the Berico team about this dilemma to make an informed choice with the help of an expert.

A useful framework is the “50 percent rule”: if the repair cost exceeds 50 percent of the cost of a new unit, and the existing unit has already surpassed its expected service life, replacement is almost always the better investment. A new unit comes with a manufacturer warranty, better energy efficiency, and a clean slate, while a patched older unit is still an older unit.

Tank vs. Tankless: Which Water Heater Is Right for Your Home?

When replacing a water heater, Greensboro homeowners have two primary options: a traditional storage tank model or a tankless water heater, and each comes with distinct advantages depending on household size and usage patterns.

Traditional tank water heaters store a set volume of water, typically 40 to 80 gallons, and keep it heated continuously. They are less expensive upfront and straightforward to install. The tradeoff is standby heat loss: you pay to keep water hot even when no one is using it.

Tankless water heaters heat water on demand, meaning they only activate when you open a hot water tap. They tend to have longer service lives, often 15 to 20 years, take up significantly less space, and eliminate standby energy loss. For larger homes in Greensboro’s Fisher Park or Starmount neighborhoods where hot water demand is high, a tankless water heater can be a strong long-term investment.

Key factors when choosing between the two:

  • Household size and peak hot water demand
  • Available fuel source (natural gas, propane, or electric)
  • Upfront budget versus long-term operating cost
  • Available space for installation
  • Local water hardness and mineral content (which affects tankless maintenance)

How Long Should a Water Heater Last in North Carolina?

Most tank-style water heaters in North Carolina last between 8 and 12 years under normal conditions, while tankless units can last 15 to 20 years with proper annual maintenance. Local water quality and usage habits both influence how quickly a unit ages.

The Piedmont Triad region has moderately hard water, which contributes to mineral scale buildup in both tank and tankless systems. Annual flushing of a tank unit, or annual descaling of a tankless unit, will meaningfully extend service life. Berico plumbing technicians can perform this maintenance as part of a scheduled service visit.

How to Extend the Life of Your Current Water Heater

Proper maintenance can add years to a water heater that is otherwise in good condition, and the steps involved are straightforward enough that most homeowners can stay on schedule with occasional professional help.

Maintenance tasks that protect your investment:

  • Flush the tank annually to remove sediment buildup
  • Test the pressure relief valve every year to confirm it is functioning
  • Inspect the anode rod every 2 to 3 years and replace it if it is heavily corroded (the anode rod is the sacrificial metal rod that prevents the tank from rusting from the inside)
  • Set the thermostat to 120 degrees Fahrenheit to reduce mineral scaling and improve efficiency
  • Insulate exposed hot water pipes in unconditioned spaces like crawlspaces and garages

Even a well-maintained unit will eventually reach the end of its service life. If you are performing all of these tasks and still experiencing the warning signs listed above, that is a strong signal that the unit has simply aged out.

Frequently Asked Questions About Water Heater Replacement in Greensboro

How do I know if my water heater needs to be replaced or just repaired?

If your water heater is less than 8 years old and has a single, isolated problem, a repair is usually the right call. If it is 10 years or older, experiencing multiple issues, or if the repair cost is approaching 50 percent of a new unit, replacement makes more sense financially and practically.

What is the average lifespan of a water heater?

Standard tank-style water heaters typically last 8 to 12 years. Tankless water heaters have longer service lives, often 15 to 20 years, when properly maintained. The exact lifespan depends on water quality, usage, and whether annual maintenance has been performed.

Is a tankless water heater worth it?

For many Greensboro homeowners, yes. Tankless water heaters eliminate standby heat loss, last significantly longer than tank models, and deliver hot water on demand without running out. The upfront cost is higher, but the long-term operating savings and extended service life often offset that difference over time.

How long does water heater replacement take?

A standard tank-to-tank swap typically takes two to four hours. A conversion from a tank unit to a tankless system takes longer, often a half-day or more, because it may require changes to the gas line, venting, and electrical connections. A Berico plumbing technician can give you a more specific estimate after reviewing your home’s setup.

Why Is My AC Freezing Up in Warm Weather?

/in /by

Why Is My AC Freezing Up in Warm Weather?

An AC unit freezes up in warm weather when restricted airflow or low refrigerant causes the evaporator coil to drop below 32 degrees Fahrenheit, allowing moisture to condense and freeze on the coil surface even on the hottest days. Seeing your outdoor AC unit covered in ice during the middle of summer is surprising to say the least, but the cause is almost always one of those two problems.

For homeowners in Eden and the surrounding Rockingham County area, freeze-ups are not an unusual summer complaint. The high humidity that settles in from June through September means there is far more moisture in the air available to freeze onto an already-cold coil. What might take hours to develop in a drier climate can happen much faster here. Understanding what is actually happening inside your system makes it easier to respond correctly and avoid making the problem worse.

What Actually Happens Inside Your AC When It Freezes

When an AC coil freezes, the refrigeration cycle has broken down: warm return air is no longer reaching the evaporator coil in sufficient volume, or refrigerant pressure has dropped too low, causing coil surface temperatures to fall below freezing and ice to accumulate.

Your AC system moves heat by circulating refrigerant between the indoor evaporator coil and the outdoor condenser coil. The evaporator coil absorbs heat from the warm air inside your home, and that heat is carried outside and released. For this process to work correctly, warm return air must flow continuously across the evaporator coil. When that airflow is blocked, or when refrigerant pressure drops due to a leak, the coil surface temperature falls below 32 degrees Fahrenheit. At that point, moisture in the air condenses and freezes directly onto the coil, and ice begins to build.

Not only does this mean the AC won’t cool your home properly, but it can also be damaged if the problem isn’t addressed. The ice itself becomes part of the problem, further insulating the coil and preventing any heat transfer from occurring, which causes more ice to form on top of what is already there.

What Causes Restricted Airflow in an AC System?

Restricted airflow is the most common cause of a frozen AC coil, and it occurs when dirty filters, closed vents, or a failing blower motor prevent enough warm return air from reaching the evaporator coil to keep it above freezing.

Figuring out exactly what is causing the AC unit to freeze up is the first step in managing to fix it correctly. When you call Berico for Eden AC repair after experiencing this issue, the technicians will look for the following issues.

  • Restricted airflow. This is a common cause of AC freeze-ups. Whether it’s from a dirty air filter, a blocked vent, or a failing blower motor, poor airflow can stop the warm air from moving across the coil as it should, and the coil will freeze on the outside as a result.
  • Dirty evaporator coils. As dust and debris build up on the coils of your air conditioner, that accumulation can interfere with heat transfer and make it harder for the system to function as it should. A layer of dust acts as insulation, further reducing the coil’s ability to absorb heat from the airstream.
  • Thermostat issues. If your thermostat isn’t controlling the system correctly, your coil may begin to ice up, even if the rest of the equipment is working as it should. A thermostat that keeps the system running longer than it should can drive the coil temperature down past the point where ice forms.

One airflow issue that is easy to overlook is closing off supply vents in unused rooms. Many homeowners assume this saves energy, but it actually raises static pressure throughout the duct system and reduces the total airflow reaching the evaporator coil. During a hot Eden summer, even a modest reduction in airflow can be enough to trigger a freeze-up.

What Causes Low Refrigerant and Why Does It Freeze the Coil?

Low refrigerant causes a frozen AC coil because a drop in refrigerant pressure lowers the boiling point of the refrigerant inside the evaporator coil, allowing the coil surface to reach temperatures well below freezing even in summer heat.

  • Low refrigerant levels. The refrigerant in your air conditioner is supposed to be within a closed system. If there is a leak, the pressure in the system will drop, and the coils can freeze up.

Refrigerant does not get “used up” the way fuel does. If your system is low on refrigerant, it means there is a leak somewhere in the refrigerant circuit. Common leak locations include the evaporator coil itself, the copper refrigerant lines, and the service valves at the outdoor unit. A refrigerant leak will not resolve on its own. Adding refrigerant without finding and repairing the leak is a temporary fix at best and can allow the leak to worsen over time.

In Eden and the Rockingham County area, Berico technicians are equipped to test refrigerant pressure, locate leaks using electronic detection equipment, and perform refrigerant leak repair before recharging the system to the manufacturer’s specified pressure. Running a system that is low on refrigerant is hard on the compressor, and compressor failure is a far more expensive outcome than addressing a leak promptly.

“In Eden, we see frozen coils most often during the first real heat wave of the summer, usually after the system has been sitting through the spring without a tune-up. A dirty filter combined with a refrigerant charge that dropped a little over the winter is often all it takes. The system struggles, the coil gets too cold, and by the time the homeowner notices ice, the unit has already been working too hard for hours. A quick inspection in the spring catches both of those problems before the heat arrives.”

Take These Steps if You Notice Ice on Your Air Conditioner

If you see ice on your AC unit, turn the system off immediately, allow the coil to thaw completely before restarting, and check your air filter and vents before calling a technician if the ice returns after the system is back on.

You don’t want to ignore ice building up on your outdoor AC unit. This is a sign that something is wrong that needs to be addressed. First, turn off the system and allow the ice to thaw and melt away completely. Once it’s thawed, consider basic fixes like opening vents or changing the air filter.

Thawing can take anywhere from one to several hours, depending on how much ice has accumulated. Switching the thermostat to “fan only” mode, if your system has that option, can speed the thaw by circulating air across the coil without running the compressor. Do not pour hot water over the coil to speed things along, as that approach can damage coil fins and refrigerant lines.

If you try these and the ice builds up again once the system is turned back on, there is something more serious at play. At this point, you want to stop using the system completely until it can be inspected and repaired by a licensed technician. It’s possible to do even more damage if you keep using the system in this condition, so be patient and wait to get it fixed.

Continuing to run a frozen AC unit puts direct stress on the compressor. The compressor is designed to handle refrigerant vapor, not liquid refrigerant that has pooled as a result of a freeze-up. When liquid refrigerant is drawn into the compressor, it can cause physical damage to internal components, a condition known as compressor slugging. Compressor replacement is one of the most significant repair costs an AC system can incur, which is why turning the system off at the first sign of ice is the right call.

How to Prevent AC Freeze-Ups Before They Start

The most reliable way to prevent a frozen AC coil is annual preventive maintenance, which includes inspecting refrigerant pressure, cleaning the evaporator coil, and confirming airflow through the system before the summer cooling season begins.

For Eden homeowners, scheduling a maintenance visit in the spring, before the heat and humidity settle in for the season, gives a technician the opportunity to catch low refrigerant, dirty coils, and airflow restrictions before they become a mid-summer emergency. Berico of Eden has served Rockingham County since 1924 and offers preventive maintenance and service contracts that keep AC systems running reliably through the hottest months of the year.

Between professional visits, homeowners can reduce freeze-up risk by:

  • Checking and replacing the air filter every 30 to 90 days, depending on the filter type and household conditions
  • Keeping all supply and return vents open and unobstructed by furniture or curtains
  • Keeping the area around the outdoor condenser unit clear of grass, debris, and overgrowth
  • Scheduling a professional tune-up once a year, ideally before the cooling season begins

Frequently Asked Questions About Frozen AC Units

Should I turn off my AC if it is frozen?

Yes. Turn the system off as soon as you notice ice on the unit. Running a frozen AC puts stress on the compressor and can cause additional damage. Switch to fan-only mode if available to help speed the thaw, and do not restart the compressor until all ice has melted completely.

How long does it take for a frozen AC to thaw?

Thaw time depends on how much ice has built up, but most units take one to several hours to thaw completely with the compressor off. Switching to fan-only mode can shorten that time. Do not restart the system until the coil is fully clear of ice.

Can a dirty filter cause my AC to freeze up?

Yes. A clogged air filter is one of the most common causes of a frozen AC coil. When the filter blocks airflow, warm return air cannot reach the evaporator coil in sufficient volume, and the coil surface drops below freezing. Replacing the filter is the first thing to check when ice appears on the unit.

Does a frozen AC mean I have a refrigerant leak?

Not necessarily. A frozen coil can result from either restricted airflow or low refrigerant. If the ice returns after you have replaced the filter and opened any blocked vents, low refrigerant from a leak is a likely cause. A licensed technician can test system pressure and locate any leak before recharging the refrigerant.

Will Your Home’s Electrical System Support EV Charger Installation?

/in , /by

Electric vehicles are more popular than ever, and more hit the road every day. If you are joining this movement, hiring a Greensboro electrician to add a charger to your home is an important step. But before the work begins, your electrical system needs to be evaluated carefully. Not every home is ready out of the box, and the gap between “probably fine” and “confirmed ready” is one that only a licensed professional can close.

Here is what Greensboro homeowners need to know about electrical requirements, panel capacity, and what the installation process actually involves.

Electrical System Requirements for EV Chargers

Most homes can support an EV charger, but the installation requires confirmed panel capacity, a dedicated circuit, proper wiring, and available breaker space before any work proceeds. With that said, it is necessary to confirm that you have sufficient panel capacity, proper wiring, and available circuit space. If you are using an outdated system currently, it might be necessary to upgrade before an EV charger can be added.

The specifics matter here. A Level 2 EV charger typically requires a 240-volt, 50-amp dedicated circuit. That means your panel needs to supply at least 50 amps of available capacity beyond what your home is already drawing. In a home running a 100-amp service panel, that headroom may not exist. In a home with 200-amp service, it usually does. A licensed electrician will perform a load calculation to confirm exactly where your system stands before any work is quoted or scheduled.

Older homes in Greensboro neighborhoods like Fisher Park and Lindley Park often have 100-amp panels and older wiring that predate the EV era entirely. In those cases, a panel upgrade is frequently part of the project, not an optional add-on.

What Does a Load Calculation Tell You?

A load calculation is a professional assessment of how much electrical capacity your home currently uses versus how much your panel can safely supply, and it determines whether adding an EV charger is safe without upgrades.

During a load calculation, your electrician reviews the amperage rating of your main panel, the circuits already in service, the wattage demands of your major appliances, and any seasonal loads like central air conditioning. North Carolina summers put sustained pressure on electrical systems. Running a heat pump or central AC at capacity while charging an EV creates a combined load that older panels may not be sized to handle safely.

This is not a step to skip or guess at. The load calculation is what separates a safe, code-compliant installation from one that trips breakers or, worse, creates a fire risk.

Take a Closer Look at the Details

Electrical systems are complicated, and work should always be done by a licensed professional. As a homeowner, it can be helpful to understand the fundamentals, so you know what’s going on when you hire an electrician. Here’s a little more about the basics of installing an EV charger.

  • Available capacity. EV chargers often need a 240-volt circuit, and your current panel may not have enough free capacity to handle such an addition without overloading.
  • Dedicated circuit requirement. An EV charger should always be on its own circuit. This will ensure safe and reliable operation without impacting the performance of other circuits around the house.
  • Panel space for new breakers. There needs to be physical space available within the panel to add a new breaker that will serve your EV charger. Most Level 2 chargers require a double-pole 50-amp breaker, which occupies two slots in your panel.
  • Proper wiring. In older homes specifically, the wiring may not be capable of supporting the higher voltage and amperage required to charge an electric vehicle. A Level 2 circuit typically requires 6-gauge copper wire run from the panel to the garage or charging location.
  • Permit and inspection. In Guilford County, EV charger installations require an electrical permit. Berico’s electricians handle the permitting process as part of the installation, ensuring the work is inspected and documented correctly.

“In Greensboro, we see a lot of homes in established neighborhoods where the panel was sized for the appliances of a different era. When a homeowner wants to add a Level 2 charger, the first thing we do is a full load calculation. In many cases, the panel needs to go from 100 amps to 200 amps before we can proceed safely. Getting that assessment done upfront saves homeowners from surprises and makes sure the installation passes inspection the first time.”

-Toni Mortera, Electrician, Berico

Do All Homes Need an Electrical Upgrade for an EV Charger?

 

No, many homes are already equipped with everything they need to add an EV charger safely. The primary variable here tends to be age. In an older home, which was built long before EV charging was even on the radar, the electrical system may not be ready to handle the demands of this addition. It’s important to have a professional electrician do a detailed load calculation to determine if your system can safely handle the added demand of an EV charger.

Newer construction in Greensboro is more likely to already have 200-amp service and the physical panel space needed for an additional double-pole breaker. Homes in those areas often move straight to installation without needing a panel upgrade. Homes in older, established neighborhoods more frequently require additional work before the charger can go in.

The Difference Between Level 1 and Level 2 Charging

Level 1 charging uses a standard 120-volt outlet and adds roughly 3 to 5 miles of range per hour, while Level 2 charging uses a dedicated 240-volt circuit and delivers 20 to 30 miles of range per hour, making it the practical choice for daily home charging.

There are two main types of EV charging setups that are common today.

  • Level 1 chargers work on a standard 120-volt outlet. These are easy to add to almost any electrical system, but they charge vehicles rather slowly. For a driver commuting 40 or 50 miles a day, overnight Level 1 charging may not fully replenish the battery before morning.
  • Level 2 chargers use a 240-volt circuit, meaning they can charge your batteries much faster. They do place more strain on the electrical system, however, so upgrades may be required. Most homeowners who are serious about daily EV use choose Level 2 for this reason.

The connector type also matters. Most Level 2 home chargers use a NEMA 14-50 outlet or are hardwired directly into the panel. Your electrician will confirm which setup your charger manufacturer recommends and install accordingly.

What Happens During a Panel Upgrade?

A panel upgrade replaces your home’s existing electrical service panel with a higher-capacity unit, typically increasing service from 100 amps to 200 amps, and it involves coordination with your local utility for the service connection.

The process includes shutting off power to the home, removing the old panel, installing the new panel and updated breakers, and reconnecting all circuits correctly. In North Carolina, this work requires an electrical permit and a final inspection by the local electrical inspector before power is restored. Berico’s licensed electricians manage that process from start to finish, including scheduling the utility coordination required when the meter needs to be pulled.

For most Greensboro homeowners, the upgrade itself is completed in a single day. The permitting and inspection timeline depends on Guilford County’s scheduling, but Berico handles all of that communication so the homeowner does not have to track it independently.

Is a Permit Really Required for EV Charger Installation?

Yes, in Guilford County, a permit is required for any new 240-volt circuit installation, including EV chargers, and skipping the permit means the work will not be inspected or documented, which can create problems when selling the home or filing an insurance claim.

Unpermitted electrical work is one of the more common issues that surfaces during home sales in the Greensboro area. When a home inspector or buyer’s electrician identifies work that was done without a permit, it can delay or derail a closing.

What panel size do I need for a Level 2 EV charger?

Most Level 2 home chargers require a 200-amp service panel to ensure safe operation alongside existing household loads. Homes with 100-amp panels may need a panel upgrade before installation. A licensed electrician will perform a load calculation to confirm what your specific home requires.

Can I install an EV charger in an older Greensboro home?

Yes, but older homes often need additional electrical work first. Homes in established Greensboro neighborhoods like Fisher Park, Lindley Park, and similar areas frequently have older service panels and wiring that must be evaluated and potentially upgraded before a Level 2 charger can be safely installed.

Do I need a permit to install an EV charger in Greensboro, NC?

Yes. Guilford County requires an electrical permit for any new 240-volt circuit installation, including Level 2 EV chargers. Berico handles the permitting process and schedules the required inspection as part of every installation.

How long does EV charger installation take?

In a home that already has sufficient panel capacity, the installation of a Level 2 charger typically takes a few hours in a single visit. If a panel upgrade is also needed, the electrical work is usually completed in one day, with the permitting and inspection process running on a separate timeline managed by Berico.
