New Requirements for Air Conditioning and Heat Pump Systems

US Dept of Energy logo

Effective January 1, 2023, the US Dept of Energy a new minimum efficiency standards for air conditioners and heat pumps will go into effect.

SEER2 and EER2

  • The new efficiency designations we be referred to as SEER2 and EER2
  • SEER2 stands for Seasonal Energy Efficiency Ratio
    • Specifically, SEER2 is the total heat removed from the conditioned space during the annual cooling season.


  • Split-system heat pumps must also achieve a minimum of 8.8 HSPF.
    • HSPF is a heating efficiency rating for heat pumps.
    • The higher the rating, the more efficient the heat pump.

Why the new requirements?

  • Every six years the Department of Energy (DOE) reanalzyes the effects of energy usage, sets minimum efficiency requirements and manages the testing standards by which those efficiencies are measured.
  • Heat pumps with a higher HSPF rating can lead to significant monthly savings on your energy bill.
  • A single package heat pump has a minimum HSPF rating of 8.2 and the split system has a minimum mark of 8.5. A heat pump that meets these minimums could result in an annual savings of more than $1,200 compared to a heat pump with a lower rating.

There are many other variables that will affect the new guidelines, such as different ratings for different regions of the country.

There are also differences in BTU ratings that will affect the rating system.
