Fun Fact Friday:
Furnaces are composed of three main parts
Although there are also parts such as filters, fittings, and ductwork, all furnaces contain these three components:
1. A burner (in gas furnaces) or a heating element (in electric furnaces): This is how the heat is created;
2. A heat exchanger: The exchanger separates combustion gas from breathable air;
3. A blower: This part sends the breathable air through the duct system in the house
