Dual Fuel Systems Make Heating Even More Efficient. You want to keep your home operating with lower energy costs, which is why you bought high efficiency HVAC products. What you might not have known is that a selection of these products are not only energy efficient when operating themselves, but they can be combined to offer even greater efficiency to your family. At Clean Air HVAC in Pacheco, 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. Once the temperature 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 rotate between the two types of heat, which optimizes energy uses and minimizes heating costs. That’s a solution you can feel good about. Check out our gas furnace and heat pump offerings to find details about each system.
