Dual Fuel Systems Make Heating Even More Efficient. You want to keep your home comfortable without paying a fortune on utility bills, which is why you bought high efficiency HVAC products. What you may not have realized is that some of these products are not only energy efficient when operating themselves, but they can be combined to produce even greater efficiency to your family. At Farnell Heating & Air Conditioning Inc in Mobile, we offer furnaces that work with heat pumps to create a dual fuel system. Combining a gas furnace with an electric heat pump allows you the ability to use two different fuel types: gas and electricity. Whenever the weather becomes too cold for your heat pump to work efficiently (usually around 32 degrees Fahrenheit), the furnace provides the rest of the power you need to stay comfy. That means you’re only using gas fuel when your desired temperature requires it. Dual fuel systems alternate between the two types of heat, which optimizes energy uses and decreases heating costs. That’s a solution you can feel good about. Check out our gas furnace and heat pump offerings to learn more about the systems individually. Give Farnell Heating & Air Conditioning Inc a ring at 251-471-2674 or make an appointment to discuss adding dual fuel capabilities to your home. We’re in Mobile – just down the road and available to help.
