The Transition from 13 to 14 SEER Heat Pumps and Air Conditioners

Did you know?

Beginning January 1, 2023, the DOE is increasing the minimum efficiencies for central air conditioners and heat pumps. The testing procedures for determining those efficiencies are changing as well.

For air conditioners in the North, the minimum efficiency will increase from 13.0 to 14.0 SEER and in the South from 14.0 to 15.0 SEER† under today’s test procedure. 

The national heat pump minimum efficiency will increase from 14.0 to 15.0 SEER.

Starting in 2023, all products must be rated using the DOE appendix M1 testing procedure, denoted as SEER2, EER2 and HSPF2. Ratings tested under M1 have been generated using external static pressures that are up to 5X higher than DOE’s pre-2023 appendix M test procedure (SEER, EER, HSPF).

In 2023, there will be new metrics and nomenclature – SEER2, EER2 and HSPF2. The new SEER2 ratings will be lower, and the minimum efficiencies will be reduced to account for the more difficult test procedures. The new test procedure will also drive changes to the airflow set point on indoor blowers (fan coils and furnaces).
