Is a heat pump more efficient than a gas furnace?
– A high efficient Heat Pump with a SEER rating of 19 or higher will produce more heat per dollar than a highly efficient gas furnace (at current utility rates). The warmer the outside temperature, the more efficient the heat pump becomes. On the flip side, the colder the outdoor temperature, the less efficient it becomes. This is one of two reasons why the system will revert back to the gas furnace. One, to produce enough heat, Second, to utilize the most efficient source of heat depending on the outdoor temperature.
