Experience the Comfort of a Dual Fuel System. Several of the fuel systems we provide at Oak Grove Heating & Air Conditioning in Hattiesburg increase your home’s efficiency more when they work in tandem with another Lennox® system than they by themselves. 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 you. Both systems are great 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 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 with increased demand for maximum MPG. You’ll be able to optimize your energy use, and you could decrease your heating spend. Typically the electric heat is used until the outdoor temperatures reach 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.
