AHRI 210/240-2023 (2020): Performance Rating of Unitary Air-conditioning & Air-source Heat Pump Equipment

Standard Scope

This standard applies to factory-made Unitary Air-conditioners and Unitary Air-source Heat Pumps with capacities less than 65,000 Btu/h as defined in Section 3 of this standard.


This standard supersedes AHRI Standard 210/240-2017 with Addendum 1

AHRI 210/240-2023 (2020), first published in May 2020, establishes a method to rate residential central air conditioners and heat pumps consistent with the test procedure codified in 10 CFR part 430, subpart B, appendix M1. The energy efficiency metrics, expressed in terms of Seasonal Energy Efficiency Ratio (SEER2), Energy Efficiency Ratio (EER2), and Heating Seasonal Performance Factor (HSPF2), are required for representations coincident with the compliance date of the new efficiency standards in the United States starting on January 1, 2023.
