How does a furnace work?

A forced-air furnace heats your home through a heating cycle that looks like this:

• Natural gas or propane is ignited in the burner.

• The flames heat a metal heat exchanger and exhaust out of the flu.

• The heat exchanger transfers its heat to the incoming air.

• The furnace's blower forces the heated air into the ductwork and distributes it throughout the home.

• As the warm air fills each room, the colder, denser air is drawn back into the furnace via the return ducts, repeating the process.

Many components work together in a furnace to help keep you comfortable. With so many types of models on the market, it can be tough to know what they are and their functions.

• Thermostat

• Draft Hood/Fan

• Burners

• Heat exchanger

• Blower

• Flue
