Experience the Comfort of a Dual Fuel System. A number of the fuel systems we provide at B & B Heating & Cooling in Florissant increase your home’s efficiency more when they work in tandem 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 work together to deliver higher efficiency and greater comfort for your home. Both systems work well 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 when there’s a higher demand for maximum MPG. You’ll be able to improve your energy use, and you could reduce your heating spend. Most times 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. Read about the details of each of our gas furnaces and heat pumps here on our website, or give us a call at 314-838-9800. B & B Heating & Cooling is located in Florissant, so you can easily make an appointment to have us do an in-home consultation and show you how a dual fuel system could work for your home.
