Experience the Comfort of a Dual Fuel System. Many of the fuel systems we provide at Dial One Mears Air Conditioning & Heating Inc in Phoenix improve your home’s efficiency more when they work in tandem 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 deliver higher efficiency and greater comfort for your home. Both systems operate efficiently 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 switch 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 when there’s a higher demand for maximum MPG. You’ll be able to optimize your energy use, and you could lower your heating costs. 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. Learn more about the details of each of our gas furnaces and heat pumps here on our website, or give us a call at 602-997-5701. Dial One Mears Air Conditioning & Heating Inc is located in Phoenix, so you can easily make an appointment to have us do an in-home consultation and show you how a dual fuel system could work for your home.
