Dual Fuel Systems Make Heating Even More Efficient. A number of the fuel systems we carry at Alltemp Comfort Services LLC in Winnsboro improve your home’s efficiency more when they work in partnership with another Lennox® system than they solo. The same is true for for our dual fuel capacity gas furnaces and heat pumps, which can be combined to deliver higher efficiency and greater comfort for your family. Both systems operate efficiently alone, but when you jointly use 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 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 improve your energy use, and you could reduce your heating spend. Typically the electric heat is used until the outdoor temperatures fall 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 803-318-6995. Alltemp Comfort Services LLC is located in Winnsboro, 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.
