For SI: 1 British thermal unit per hour = 0.2931 W, °C = [(°F) - 32]/1.8.

^a Chapter 6 contains a complete specification of the referenced standards, which include test procedures, including the reference year version of the test procedure.

^b Single-phase, U.S. air-cooled heat pumps less than 65,000 Btu/h are regulated as consumer products by the U.S. Department of Energy Code of Federal Regulations DOE 10 C.F.R. 430 . SEER, SEER2, and HSPF values for single-phase products are set by the U.S. Department of Energy.

^c DOE 10 C.F.R. 430 Subpart B Appendix MI includes the test procedure updates effective 1/1/2023 that will be incorporated into AHRI 210/240-2023.
