Winter is coming fast, and it certainly doesn’t let us forget it! Blustery winds that chill through to your bones, iced up car windows, and snow days, this often means that the temperature outside has reached as low as 30 degrees or colder when wind chill is considered!

A large reason that we are able to live comfortably in this weather is because of a special appliance that is often tucked away in your house and not really considered on a daily basis: your furnace.

Furnaces consist of three major components: the burners, a draft inducer, and a heat exchanger. When you bump up your thermostat or it detects that the temperature of your house/building has dropped below its designated temperature, it send a signal to the furnace to ignite its burners.

After the burners are ignited, the draft inducer kicks into action, and sucks the hot gases from the burners towards the heat exchanger. A draft inducer looks similar to a cars turbocharger, and works in a similar manner also. While the hot gas is moved through the heat exchanger, the furnace also brings air from your house through the heat exchanger in order to warm it. If the draft inducer is dirty in any way, this could cause the unit from igniting or staying lit.

And there you have it! Now you understand the basics of how a furnace works. Always use a professional to carry out maintenance and repairs to keep it running at peak efficiency and safe for the whole family.
