Complete Heat and Air: How a Gas Furnace Works

Complete Heat and Air

Gas Furnaces
Like heat pumps, furnaces keep your home warm in the winter and serve as an important part of your air conditioning system in the summer. In a furnace, gas or oil is combusted in a burner and then heat produced from that reaction passes through a heat exchanger where it is transferred to the air distribution system. The ductwork throughout a home carries and disperses the conditioned air and the flue or vent pipe releases the byproducts, such as carbon dioxide and water vapor, outside the home.
