Dual Fuel Systems Make Heating Even More Efficient. Many of the fuel systems we provide at Air Unlimited Heating & Cooling in Liberty and the Kansas City Metro Area increase your home’s efficiency more when they work together with another Lennox® system than they by themselves. 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 your home. Both systems are great 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 alternate between electric or gas heat based 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 when there’s a higher demand for maximum MPG. You’ll be able to improve your energy use, and you could decrease your heating budget. 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.
