Experience the Comfort of a Dual Fuel System. Many of the fuel systems we provide at Jett's Heating & Air Inc. in Crystal Lake improve your home’s efficiency more when they work in partnership with another Lennox® system than they do alone. This is true for for our dual fuel capacity gas furnaces and heat pumps, which can pair up to offer higher efficiency and greater comfort for you. 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 preferred 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 optimize your energy use, and you could lower 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.

Jett's Heating & Air Inc. is located in Crystal Lake, 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.
