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 have high efficiency HVAC products. What you may not have known is that some of these products are not only energy efficient when operating alone, but they can be combined to produce even greater efficiency to your family. At Alltemp Comfort Services LLC in Columbia, 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. 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 warm. 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 lowers heating costs. That’s a solution we like to see. Explore our gas furnace and heat pump offerings to find details about each system.
