A dual fuel system (also called hybrid heat) is comprised of a heat pump, indoor coil and gas furnace. A heat pump is an air conditioner that also has the ability to heat your home. With a dual fuel system, the heat pump will heat your home majority of the time. The gas furnace provides back up heat and only will come on if it is below 40 degrees. For Atlanta, dual fuel is more efficient than an all-electric system or a traditional split system (comprised of a gas furnace and an air conditioner). In addition to the energy savings, a dual fuel system will not dry your skin out as much as a traditional system. However, it does provide a different comfort level than a traditional gas furnace so it is important to talk with our team about which option is best for you and your family.
