Shop Dual Fuel Packaged Units—smart all-in-one systems that combine an electric heat pump with a gas furnace for the best of both worlds. In mild weather, the energy-efficient heat pump handles heating and cooling. When outdoor temperatures drop too low for the heat pump to run efficiently, the gas furnace automatically takes over to deliver powerful, reliable heat. Everything is combined in a single outdoor cabinet, saving valuable indoor space. Dual fuel units are ideal for homes, manufactured homes, and light commercial properties especially in Northern States that want maximum efficiency without sacrificing heating strength. Wer are family owned and operated for over 30 years, we offer fast shipping, free duct designs with every system, honest upfront pricing, and expert technical and warranty support.
