Experience the Comfort of a Dual Fuel System. Several of the fuel systems we carry at Controlled Comfort HVAC Inc in Carpentersville improve your home’s efficiency more when they work in partnership 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 offer higher efficiency and greater comfort for your home. Both systems operate efficiently alone, 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 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 with increased 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 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.
