  SUMMARY: The U.S. Department of Energy ("DOE") amends its test procedures for air -cooled, three -
phase, small commercial package air conditioning and heating equipment with a cooling capacity of 
less than 65,000 British thermal units per hour ("Btu/h") and air -cooled, three -phase, variable 
refrigerant flow air conditioners and heat pumps with a cooling capacity of less than 65,000 Btu/h 
to incorporate by reference the latest version of the relevant industry test standard. DOE adopts th e 
seasonal energy efficiency ratio 2 ("SEER2") and heating seasonal performance factor 2 ("HSPF2") 
metrics specified by that industry test standard in the DOE test procedures for the three - phase 
equipment that is the subject of this final rule. Additional ly, DOE amends certain provisions for 
representations and enforcement for this equipment to harmonize with single -phase products.  
The U.S. Department of Energy (DOE) incorporates by reference (into the Code of Federal 
Regulations ) the following industry standards as follows:  
ANSI/AHRI Standard 210/240 -2008, "2008 Standard for Performance Rating of Unitary Air -
Conditioning & Air -Source Heat Pump Equipment", approved 2011 and updated by addendum 1 in 
June 2011 and addendum 2 in March 2012 ("ANSI/AHRI 210/240 -2008") — into 10 CFR Part 431 . 
AHRI Standard 210/240 -2023, "2023 Performance Rating of Unitary Air -conditioning & A ir-source 
Heat Pump Equipment", copyright 2020 ("AHRI 210/240 -2023") — into parts 10 CFR Parts 429 and 
431. 
ANSI/AHRI Standard 1230 -2010, "2010 Standard for Performance Rating of Variable Refrigerant 
Flow Multi -Split Air -Conditioning and Heat Pump Equipment", approved 2 August 2010 and updated 
by ad dendum 1 in March 2011 ("ANSI/AHRI 1230 -2010") — into 10 CFR Part 431 . 
Copies of these standards can be obtained from the AHRI website by going to www.ahrinet.org . 
ANSI/ASHRAE Standard 37 -2009, "Methods of Testing for Rating Electrically Driven Unitary Air -
Conditioning and Heat Pump Equipment", ASHRAE approved June 24, 2009 ("ANSI/ASHRAE 37 -
2009")—into part into 10 CFR Part 431 . 
Copies of ANSI/ASHRAE 37 -2009 can be obtained from the American National Standards Institute, 
25 W. 43rd Street, 4th Floor, New York, NY 10036, Phone: +1 (212) 642 -4900, or online at 
webstore.ansi.org . 
DATES: The effective date of this rule is 17 January 2023. The final rule changes will be mandatory 
for product testing starting 11 December 2023. The incorporation by reference of cer tain material 
listed in the rule is approved by the Director of the Federal Register on 17 January 2023. The 
incorporation by reference of certain other material listed in the rule was approved by the Director 
of the Federal Register on 6 February 2017.  
This final rule and the proposed rule notified as G/TBT/N/USA/1811  are identified by Docket Number 
EERE-2017-BT-TP-0031. The Docket Folder is available on Regulations.gov a t
