Energy Star qualified heat pump models are up to 30 percent more energy efficient than standard equipment. However, we suggest considering how much heat you use during the colder months. When choosing whether a heat pump is right for you, homeowners who rarely use heat or use it to only “knock the chill off” might not find the return on investment (R.O.I.) that more frequent heat users experience. Your return on investment for the added upfront costs of a heat pump can only be achieved when the system is being used in the “heat” mode.
