A dual fuel heating system is a combination of a heat pump and a furnace. The heat pump runs on electricity, while the furnace uses a fossil fuel — this is why it’s called a dual fuel system. This type of system is especially suited to the climate in Hoover, which doesn’t experience many days of below-freezing temperatures.
During the cold season, the heat pump gathers heat from the ambient air and pumps it through the furnace and into your home. When the temperature drops low enough, the heat pump turns off and the furnace takes over, keeping your house nice and warm. Switching from heat pump to furnace ensures that your home is always heated using the most efficient method.
