What the agency says
This final rule amends the Federal test procedure for central air conditioners and heat pumps ("CAC/HPs") to incorporate by reference the latest versions of the applicable industry standards. Specifically, DOE is incorporating by reference the latest version of the relevant industry consensus test standard, AHRI 210/240-2024 (I-P) for the current test procedure for CAC/HPs ("appendix M1") for measuring the current cooling and heating metrics--seasonal energy efficiency ratio 2 ("SEER2") and heating seasonal performance factor 2 ("HSPF2"). DOE is incorporating by reference the new industry consensus test standard, AHRI 1600-2024 (I-P), for a new test procedure ("appendix M2") for CAC/HPs that adopts two new metrics--seasonal cooling and off-mode rating efficiency ("SCORE") and seasonal heating and off-mode rating efficiency ("SHORE"). Testing to the SCORE and SHORE metrics would not be required until such time as compliance is required with any amended energy conservation standard based on the new metrics. Additionally, DOE is amending certain provisions of DOE's regulations related to representations and enforcement for CAC/HPs.
