Dual Fuel Systems Make Heating Even More Efficient. A number of the fuel systems we provide at Craig's Heating & Cooling in Bountiful increase your home’s efficiency more when they work together with another Lennox® system than they do alone. 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 family. Both systems work well by themselves, 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 change between electric or gas heat in accordance with 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 demand for maximum MPG. You’ll be able to hone your energy use, and you could lower your heating spend. 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.

Craig's Heating & Cooling is located in Bountiful, so you can easily schedule an appointment to have us do an in-home consultation and show you how a dual fuel system could work for your home.
