Dual Fuel Systems Make Heating Even More Efficient. Many of the fuel systems we provide at Carefree Heating and Cooling, LLC in Hamilton boost your home’s efficiency more when they work in partnership with another Lennox® system than they do alone. This is the case with for our dual fuel capacity gas furnaces and heat pumps, which can pair up to provide higher efficiency and greater comfort for you. Both systems are great by themselves, but when you marry the gas furnace and the heat pump, you’re taking advantage of both gas and electric fuel. The two systems will change between electric or gas heat depending on your desired indoor air temperature and the operating efficiency of each unit. This works the same way as a hybrid car, alternating between electric power at low speed and gas power with increased demand for maximum MPG. You’ll be able to hone your energy use, and you could lower your heating budget. Typically the electric heat is used until the outdoor temperatures fall to about 32 degrees Fahrenheit before switching to gas. Not only will you feel comfortable, but you can feel good about the efficiency of your dual fuel systems, too.
