  Than 65,000 Btu/h and Air -Cooled, Three -Phase, Variable Refrigerant Flow Air Con ditioners and Heat 
Pumps With a Cooling Capacity of Less Than 65,000 Btu/h  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Final rule  
SUMMARY: In this final rule, the U.S. Department of Energy (DOE or the Department) is adopting 
amended energy conservation standards for air cooled, three -phase, small commercial air 
conditioners and heat pumps with a cooling capacity o f less than 65,000 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  that rely on new efficiency metrics and align with amended efficiency levels in the 
industry s tandard. For the relevant equipment classes, DOE has determined that it lacks clear and 
convincing evidence required by the statute to adopt standards more stringent than the levels 
specified in the industry standard.  
DATES: The effective date of this rule  is 1 August 2023. Compliance with the amended standards 
established for air cooled, three -phase, small commercial air conditioners and heat pumps with a 
cooling capacity of less than 65,000 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 in this final rule is 
required on and after 1 January 2025.  
This final rule and the notice of proposed rulemaking; request for comment notified as 
G/TBT/N/USA/1846  are identified by Docket Number EERE -2022-BT-STD-0008. The Docket Folder 
is available from Regulations.gov at https://www.regulations.gov/docket/EERE -2022-BT-STD-
