Dual Fuel Systems

With a traditional heat pump system, you would have to use less electricity if you wanted to save more money. However, a Dual-Fuel system combines the benefits of intelligent control for gas and electric heating to create an intuitive system that can react to changing outdoor conditions.

No matter the outside temperature, a Dual-Fuel system will automatically choose your home's most efficient fuel source. This means you will stay warm in the winter, cool in the summer, and save money year-round.

Creating a Dual-Fuel system is straightforward, and your local EverRest Extreme Comfort dealer has the necessary tools to set one up for your home. This involves simply pairing one of our outdoor heat pump units with a natural gas furnace. A Dual-Fuel system is more efficient in the colder winter months than a traditional heat pump system, and it will keep you comfortable without any capacity loss, even when it is icy outside.
