A dual fuel system is an electric heat pump combined with a gas furnace. The heat pump handles the cooling and most of the heating, with the furnace kicking in during the coldest weather. Heat pumps are generally more energy efficient than furnaces and air conditioners, which makes dual fuel systems a great choice for folks who live in colder climates. Your heat pump will be able to handle your cooling at a lower cost, while your system will have a powerful furnace that will kick in when it gets too cold for the heat pump to handle.
