## Abstract

The U.S. Department of Energy ("DOE") published a direct final rule to establish amended energy conservation standards for air- cooled commercial package air conditioners and heat pumps with a rated cooling capacity greater than or equal to 65,000 Btu/h in the Federal Register on May 20, 2024. DOE has determined that the comments received in response to the direct final rule do not provide a reasonable basis for withdrawing the direct final rule. Therefore, DOE provides this document confirming the effective and compliance dates of those standards.
