Main Components of a Home Heating System

furnace components

Do you know how your furnace operates? To better understand the technology you use on a daily basis, read on and learn more about the main components of your heating system.

Fuel Type

Your furnace burns fuel to generate heat which in turn warms your home. Common fuel sources include electric, natural gas, propane, or oil.

HVAC System Thermostat

Though separated from the ductwork and furnace itself, the thermostat controls the heating cycle. When the temperature gets below the thermostat setting, it will activate the furnace to begin heating the home.

Furnace Burner

The heat created by a furnace is generated in the burner. For example, natural gas ignites to create heat in a sealed combustion chamber and receives air from a vent to the outdoors. The sealed chamber protects you from the poisonous exhaust fumes created in the burner.

Heat Exchanger

Because the burner is sealed, the heat exchanger is necessary to contract the heat generated by the burner through the combustion chamber.

Blower

Once the hot air is created, a very large fan called a blower moves the heated air through the ductwork to the vents in the home.

Filter Rack

In most cases, the furnace filter is located in the HVAC system filter rack. It's important to know where the filter(s) are located so that you can ensure their cleanliness and proper system airflow.
