Dual Fuel Systems

With a traditional heating and cooling system, if you wanted to save more, you had to use less. But a Dual Fuel system combines the benefits of intelligent control for both gas and electric heating to create an intuitive system that can actually react to changing conditions.

No matter what the temperature is outside, a Dual Fuel system will automatically select the fuel source most efficient for your home, which means you'll stay warm in the winter, cool in the summer and save money all year long.

To design a Dual Fuel system for your home, we professionally match one of our heat pump units with a natural gas furnace. Contact us to see how much energy you can save over your existing system.
