Experience the Comfort of a Dual Fuel System. 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 known is that certain products are not only energy efficient when operating alone, but they can be combined to produce even greater efficiency to your family. At Custom Air Systems Inc in Port St. Lucie, 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 run efficiently (usually around 32 degrees Fahrenheit), the furnace provides the additional power you need to stay cozy. 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 you can feel good about. Browse our gas furnace and heat pump offerings to find information about each product.
