The single biggest advantage of a heat pump, is the system’s ability to offer both heating and cooling functions. In some cases, heat pumps are quite a bit more energy efficient than traditional heating systems. The system doesn’t combust fuel to generate heat, instead using refrigerant to move heat from one place to another.
Not having to burn fuel means that you don’t have to spend money on natural gas on top of the electricity required to run the system every month. Ultimately, heat pumps are convenient, good for the environment, and save a lot of money on operating costs in the long run.
