Dual Fuel Systems Make Heating Even More Efficient. Several of the fuel systems we offer at All Seasons Comfort Systems Inc in Reeds Spring improve your home’s efficiency more when they work together with another Lennox® system than they solo. This 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 on their own, 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 chosen 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 optimize your energy use, and you could lower your heating spend. Most times 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.
