Description: The U.S. Environmental Protection
Agency (EPA) is amending a provision of the 2023 Technology Transitions
regulations
promulgated under the American Innovation and
Manufacturing Act of 2020. This action provides until 1 January 2027, for the
installation of certain new variable refrigerant flow air conditioning and heat
pump systems which use components manufactured in the United States or imported
into the United States prior to 1 January 2026. This action also provides until
1 January 2028, for the installation of certain new variable refrigerant flow
air conditioning and heat pump systems if a building permit that approves the
use of a hydrofluorocarbon or blend containing a hydrofluorocarbon in such a
system was issued prior to 5 October 2023, provided that the system uses
components manufactured in the United States or imported into the United States
prior to 1 January 2026. This action will mitigate the potential for stranded
inventory of variable refrigerant flow systems.
This final rule is effective on 13 January 2025.
