Dual Fuel Systems Make Heating Even More Efficient. A number of the fuel systems we carry at Faust Air Conditioning and Heating in Wharton improve your home’s efficiency more when they work together 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 work together to offer higher efficiency and greater comfort for you. Both systems work well by themselves, but when you jointly use 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 based 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 improve your energy use, and you could lower your heating costs. Typically the electric heat is used until the outdoor temperatures reach 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.
