What’s a Dual Fuel System?


Advances in HVAC technology have given our customers exceptional energy efficiency and increased comfort. One of the more recent types of systems that you should be on the look out for is the dual fuel system. As its name suggests, this is a hybrid system that joins two different mechanisms together in order to take advantage of the benefits of each. A dual fuel system makes for a particularly apt choice in our climate, and we can tell you everything you need to know.

Two Different Systems in One

A dual fuel system combines an electric heat pump with a gas furnace. An air source heat pump works much like a conventional air conditioner in that it circulates refrigerant through a series of phase changes in order to transfer thermal energy from one place to another. It can be used for both heating and cooling because it is able to reverse the flow of refrigerant. A gas furnace is one of the most popular heating systems around. But why combine them?

Benefits of Dual Fuel Systems

Having two different heating systems in one allows you to rely on the heat pump for the majority of the year, and the gas furnace on those particularly chilly winter evenings. Every home has a point at which the heat pump is no longer energy efficient and that’s precisely the point at which your gas furnace takes over. During the summer months, a dual fuel system provides you with ample cooling. Opting for this type of system can lead to substantial savings in the long-term.
