A dual-fuel system, also known as a hybrid system, combines an electric heat pump with a gas furnace to provide the most efficient heating possible in any weather. When the outside temperature is moderate, the high-efficiency Heat Pump Condenser provides the warmth; when it gets extremely cold, the system automatically switches to the gas furnace. This ensures you always have the most cost-effective heat source running based on your local utility rates. Many of our Mobile Home Complete Systems can be configured as dual-fuel to offer maximum flexibility for homeowners in changing climates. You will need a Fossil Fuel Kit or a compatible thermostat to manage the transition between the two units. This setup is perfect for those who want the comfort of a Mobile Home Gas Furnaces but the efficiency of electric cooling. It represents the ultimate "best of both worlds" solution for modern residential heating and cooling.
