Experience the Comfort of a Dual Fuel System. You want to keep your home operating with lower energy costs, which is why you have high efficiency HVAC products. What you may not have known is that certain products are not only energy efficient working by themselves, but they can be combined to offer even greater efficiency to your family. At Falls Mechanical Services LLC in Great Falls, we offer furnaces that work with heat pumps to create a dual fuel system. Combining a gas furnace with an electric heat pump gives you the ability to use two different fuel types: gas and electricity. Once the temperature becomes too cold for your heat pump to run efficiently (usually around 32 degrees Fahrenheit), the furnace starts up to provide the extra power you need to stay comfy. That means you’re only using gas fuel when it’s needed. Dual fuel systems rotate between the two types of heat, which optimizes energy uses and decreases heating costs. That’s a solution we like to see. Check out our gas furnace and heat pump offerings to learn more about the systems individually.
