How Does a Furnace Heat a House?

Central heating is one of the best possible features to have in a home. Simply by adjusting the thermostat, the furnace will jump into action and bring the space inside the home up to a comfortable temperature for you and your family. It’s a function that most people take for granted, but do you actually know how it works? Learn a little more about furnaces in the article below.

A Simple Concept

While the inner workings are anything but simple – which is why a professional technician is always required for furnace repair – the idea behind how a furnace heats your home is pretty straightforward. First, it pulls air into the furnace unit from a central location in the house, and that air passes through a filter to make sure it is as clean as possible. Then, the air goes into the heat exchanger, a unit that has been warmed by using one of a number of potential energy sources. Furnaces can be powered by natural gas, propane, electricity, oil, and more.


Once the air has been heated by going through the heat exchanger, a blower will push it out into the ducts and toward the vents that are placed in rooms throughout the house. This creates an ongoing cycle of cool air being gradually warmed – and that cycle will continue until the home has reached the desired temperature. The process is controlled by a unit known as a thermostat, which can be set for not only what temperature you want the house to reach, but also what times of the day (and days of the week) you want it to run.


Potential Issues

Most of the time, your furnace will work nicely without requiring much attention from you. As long as the thermostat is set correctly, you’ll be comfortable. With that said, there are some things you need to pay attention to in order to get good performance throughout the cold part of the year. Here are two important points –


  • Having enough fuel. Depending on the fuel source required for your furnace, you might keep a tank on your property that is used to run this appliance. In that case, work with a company like Berico to stay topped up with propane or heating oil to make sure you don’t find yourself stuck in the cold when your tank runs out.


  • Dirty air filter. It’s easy enough to forget about changing the air filter in your furnace system, but that’s one of the most important HVAC tasks – and one that most homeowners can handle on their own. Change out the filter frequently to make sure clean air is flowing through the system.
