The cooling efficiency of a heat pump, like an air conditioner, is measured by its SEER. Because (unlike an air conditioner) a heat pump has a heating capacity, its heating efficiency is measured by the unit's HSPF. The minimum SEER rating for heat pumps was raised – by the U.S. Dept of Energy – in 2015 to 14; HSPF for heat pumps now range from 8.2 (minimum) to 10.5.
By installing a new high efficient heat pump, you may qualify for up to a $400 mail-in rebate from American Electric Power. Hetter will provide rebate applications for qualifying equipment.
On January 1, 2010 the U.S. Department of Energy mandated that all manufacturers could no longer produce R-22 based heat pumps and air conditioners. All outdoor units now must be R-410A refrigerant.
The indoor unit in a heat pump or all electric system is referred to as the air handler. The air handler consists of a blower motor, evaporator coil and auxiliary heat package. A common misconception is that this unit is the home's primary source of heat when - in reality - it is only a back-up. All manufacturers offer air handlers with a standard blower motor and a variable speed blower.
Because of the high cost of electricity & because in central Ohio we heat 7 or 8 months out of the year, we at Hetter Heating & Cooling recommend, when purchasing a heat pump, focus on a unit with an HSPF of at least 9.0 or higher. For more information, go to www.trane.com.
