How Does A Furnace Work?: All You Need To Know

Did you know that your furnace is one of the most important appliances in your home? It’s responsible for heating your indoor spaces all winter long, so it’s important to make sure it’s in good condition. 

This post will explain how a furnace works and discuss some common problems you may experience with yours. By understanding how your furnace works, you can better care for it and avoid costly repairs. So, let’s get started!

What Is A Furnace?

A furnace is a device that heats your home by blowing hot air through ducts. It consists of three main parts: the blower, the heat exchanger, and the burner. The blower pushes air over the heat exchanger to heat it, and then the heated air passes through the burner to be reheated. This process repeats until the desired temperature is reached.

Furnaces are typically powered by gas, oil, or electricity. Gas furnaces are the most common type, and they work by igniting a small pilot light that starts up the main burner. Oil furnaces use a small pump to deliver fuel to the burner, while electric furnaces heat a wire coil to create heat.

How To Maintain Your Furnace

Now that you know how your furnace works, let’s talk about some common problems you may experience. Furnace repairs can be expensive and frustrating if done incorrectly, so it’s important to do what you can to prevent them in the first place. One of the best ways is by regularly maintaining your furnace for peak performance.

If you have a gas furnace, be sure to have your pilot light checked every year. If it’s out, you’ll need to relight it before the furnace works. You can also call a professional HVAC company like Fusion Plumbing & Air to do this for you.

If you have an oil furnace, be sure to change the filter every three months and have the oil tank checked every year. You should also inspect the hoses and fittings for leaks and ensure the furnace is properly grounded.

If you have an electric furnace, be sure to change the filters every month and clean the coils every year. You should also check the wiring for signs of wear and tear.
