# SUPPLEMENTARY INFORMATION:

                     On January 20, 2025, the Assistant to the President and Chief of Staff (“Chief of Staff”) issued a memorandum outlining the President's plan for managing the Federal regulatory process at the outset of the new Administration. In implementation of one of the measures directed by that memorandum, the United States Department of Energy (“DOE”) hereby temporarily postpones the effective date of its final rule amending the test procedures for central air conditioners and heat pumps published in the                     **Federal Register**                     on January 7, 2025 (90 FR 1224). The January 7, 2025, rule amends the test procedures for measuring the energy efficiency of central air conditioners and heat pumps by incorporating the latest version of the applicable industry standards and adopting a new industry standard that would apply to future energy conservation standards based on two new energy efficiency metrics. Consistent with the Chief of Staff's memorandum of January 20, 2025, DOE is temporarily postponing the effective date of the final rule to March 21, 2025. The temporary delay in effective date is necessary to give DOE officials the opportunity for further review and consideration of new regulations, consistent with the President's memorandum of January 20, 2025.                

To the extent that 5 U.S.C. 553 applies to this action, it is exempt from notice and comment because it constitutes a rule of procedure under 5 U.S.C. 553(b)(A) and for which no notice of hearing is required by statute. The delay of the effective date to March 21, 2025, does not affect the compliance date for this rule, which remains July 7, 2025. DOE is, however, seeking comment on any further delay of the effective date, including the impacts of such delay, as well as comment on the legal, factual, or policy issues raised by the rule.
