Dual Fuel Split Systems combine the best of both worlds—efficient electric heating and cooling through a heat pump, and powerful backup heating from a natural gas or propane (LP) furnace. In mild weather, the heat pump keeps your home comfortable while using less energy. When outdoor temperatures drop too low for the heat pump to operate efficiently, the system automatically switches to gas heat for reliable, strong warmth. These setups offer maximum energy savings without sacrificing cold weather performance. Budget Heating and Air is family owned and operated for over 30 years, we proudly offer fast shipping, free duct designs, honest pricing, and expert warranty and technical support.
