A dual fuel heating system uses a gas furnace, which runs on natural gas or propane to produce heat, and an electric outdoor heat pump.
During the winter months, the heat pump delivers efficient heat to the home or business. As winter progresses and temperatures continue to drop outside, the heat pump switches on the gas furnace for fast, dependable heat in freezing temperatures.
While typical heat pump systems use auxiliary heaters within the air handler, which can be inefficient, dual fuel systems have two efficient heating options, always adapting and ready to be used depending on the external conditions.
