Description:  Energy Conservation Program: Test Procedure for Room Air Conditioners  
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of Energy  
ACTION: Final rule  
SUMMARY: On 11 June 2020, the U.S. Department of Energy ("DOE") issued a notice of proposed 
rulemaking ("NOPR") to amend the test procedure for room air conditioners ("room ACs"). That 
proposed rulemaking serves as the basis for the fina l rule. Specifically, this final rule adopts the 
following updates to the test procedure for room ACs at appendix F: Incorporate by reference current 
versions of applicable industry standards; establish test provisions to measure energy use of 
variable -speed room ACs during a representative average use cycle; update definitions to define key 
terms and support provisions for testing variable -speed room ACs; and incorporate specifications

  and minor corrections to improve the test procedure repeatability, repr oducibility, and overall 
readability. This final rule does not modify the test procedures for single -speed room ACs and does 
not affect the measured energy use for these models. The provisions established to measure energy 
use of variable -speed room ACs wi ll improve the representativeness of the measured energy use of 
these models.  
DATES: Effective date: The effective date of this rule is 28 April 2021.  
Compliance date: The final rule changes will be mandatory for product testing starting 27 September 
2021.  
Incorporation by reference: The incorporation by reference of certain publications listed in the rule 
is approved by the Director of the Federal Register on 28 April 2021. The incorporation by reference 
of certain other publications listed in this rulemak ing were approved by the Director of the Federal 
Register on 7 March 2012, and 31 July 2015.
