Dual Fuel Systems Make Heating Even More Efficient. Several of the fuel systems we provide at Lycoming Heating Company in Williamsport increase your home’s efficiency more when they work in tandem with another Lennox® system than they solo. This is the case with for our dual fuel capacity gas furnaces and heat pumps, which can pair up to deliver higher efficiency and greater comfort for your home. Both systems operate efficiently alone, 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 preferred 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 optimize your energy use, and you could reduce your heating budget. Most times 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.
