Dual Fuel Systems Make Heating Even More Efficient. You want to keep your home operating with lower energy costs, which is why you purchase high efficiency HVAC products. What you might not have known is that a selection of these products are not only energy efficient working by themselves, but they can be combined to deliver even greater efficiency to your family. At Davis Heating & Air Conditioning in Rocky Mount, we offer furnaces that work with heat pumps to create a dual fuel system. Combining a gas furnace with an electric heat pump enables you to use two different fuel types: gas and electricity. When it’s too cold for your heat pump to work efficiently (usually around 32 degrees Fahrenheit), the furnace kicks in to provide the rest of the power you need to stay comfy. That means you’re only using gas fuel when it’s needed. Dual fuel systems switch between the two types of heat, which optimizes energy uses and minimizes heating costs. That’s a good solution, if we may say so ourselves. Check out our gas furnace and heat pump offerings to learn more about the systems individually.

We’re in Rocky Mount – just down the road and available to help.
