3.5 Ton

Our 3.5 Ton (3 1/2 Ton) Dual Fuel Packaged Units deliver efficient year-round comfort for homes, offices, or light commercial spaces between approximately 1,800 and 2,100 square feet. These all-in-one systems combine an electric heat pump for everyday heating and cooling with a natural gas or propane (LP) furnace for backup heat when temperatures drop. The system automatically switches between electric and gas based on outdoor conditions, maximizing efficiency while ensuring reliable warmth. Ideal for rooftop installations, garages, manufactured homes, and properties with space constraints. Family owned and operated for over 30 years, we offer fast shipping, free duct designs, honest pricing, and expert technical and warranty support.
