Experience the Comfort of a Dual Fuel System. A number of the fuel systems we provide at Temptrol Heating & Cooling Inc. in Antioch boost your home’s efficiency more when they work together with another Lennox® system than they by themselves. This is true for for our dual fuel capacity gas furnaces and heat pumps, which can work together to deliver higher efficiency and greater comfort for your home. Both systems are great by themselves, but when you marry 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 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. Most times 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.
