Experience the Comfort of a Dual Fuel System. A number of the fuel systems we carry at Air Alliance Team in Ballwin and St. Charles increase your home’s efficiency more when they work together with another Lennox® system than they solo. 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 your home. Both systems work well on their own, but when you combine the gas furnace and the heat pump, you’re taking advantage of both gas and electric fuel. The two systems will alternate between electric or gas heat depending 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. Usually the electric heat is used until the outdoor temperatures dip 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. Read about the details of each of our gas furnaces and heat pumps here on our website, or give us a call at 636-206-4250. Air Alliance Team is located in Ballwin and St. Charles, 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.
