Dual Fuel Systems Make Heating Even More Efficient. A number of the fuel systems we offer at Cool Power LLC in Hauppauge boost 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 deliver higher efficiency and greater comfort for you. Both systems work well 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 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 increased demand for maximum MPG. You’ll be able to improve your energy use, and you could lower your heating budget. 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. Learn more about the details of each of our gas furnaces and heat pumps here on our website, or give us a call at 631-360-2665. Cool Power LLC is located in Hauppauge, 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.
