Dual Fuel Systems Make Heating Even More Efficient. Several of the fuel systems we carry at ACS Heating and Air Conditioning in Tucker increase your home’s efficiency more when they work in partnership 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 provide 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 chosen 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 demand for maximum MPG. You’ll be able to hone your energy use, and you could decrease 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. Learn more about the details of each of our gas furnaces and heat pumps here on our website, or give us a call at 770-450-1539. ACS Heating and Air Conditioning is located in Tucker, so you can easily arrange an appointment to have us do an in-home consultation and show you how a dual fuel system could work for your home.
