Heat Pumps

Heat pumps are an excellent option for your home comfort system if electricity is your primary energy source. They can provide both heating and cooling. Like air conditioners, heat pumps have SEER2 and EER2 ratings for measuring cooling efficiency, with an added Heating Seasonal Performance Factor (HSPF2) rating for measuring heating efficiency.

The Department of Energy (DOE) has established minimum efficiency national standards for heat pumps at 14.3 SEER2 and 7.5 HSPF2 across the United States. Higher SEER2 and HSPF2 ratings indicate greater energy savings.

EverRest Extreme Comfort Can Help You Choose

Heat pumps are a highly efficient alternative to using electric baseboard heating alone. They work like air conditioners in the summer but reverse the process in the winter to provide heat for your home. In milder climates, supplemental electric resistance heat provides additional heating capacity during colder winter months. Your local EverRest Extreme Comfort dealer may match your heat pumps with a gas furnace in freezing weather to offer efficient Dual-Fuel operation, even at temperatures below zero.

Get ready to experience a new level of comfort with our wide range of heat pumps, each equipped with advanced features. These include high-efficiency inverter- and 2-stage compressors, variable-speed fan operation, and advanced connected control systems. Your local EverRest Extreme Comfort dealer can design a system with these features that enhance your home's comfort and maximize energy savings.

SEER Versus SEER2

SEER2 is an updated rating standard introduced by the DOE. The DOE designed the SEER2 standards to assess typical home operating conditions more accurately than the older SEER rating standards, which used precise protocols to determine ratings at ideal conditions. The SEER2 standards incorporate updated testing procedures, better indicating how a unit operates in real-world scenarios.

Like miles-per-gallon for a car, SEER2 and EER2 provide a simple method to compare the efficiencies of various products – the higher the rating, the more efficient the unit.

EER2 and SEER2

EER2 and SEER2 both evaluate an air conditioner’s energy efficiency, but they apply to two different types of temperature conditions:

  • EER2 measures an air conditioner’s efficiency at the peak cooling temperature of 95°F.
  • SEER2 measures an air conditioner’s efficiency throughout an entire cooling season, with temperatures ranging from 65°F to 104°F.
