In June, the U.S. EPA published a new proposed rule that may impact the sell-through period for VRF systems using high-GWP refrigerants under the AIM Act. As a building owner, operator, and/or facility manager, you may want to be aware of this action and determine how you could be affected.
1-Year Extension Proposed for VRF Systems
The proposal revises the Technology Transitions rule published in October 2023. Originally, the rule banned the installation of VRF systems using high-GWP HFC refrigerants like R-410A on January 1, 2026.
The new proposed rule would allow for one additional year—that is, until January 1, 2027—for the installation of new VRF systems that are 65,000 BTU/h or larger when using components that were manufactured in the U.S. or imported in the U.S. before January 1, 2026.
The proposed rule explains,
"The existing January 1, 2026, compliance date for the installation of certain variable refrigerant flow systems may result in significant stranded inventory intended for new construction …
[This action is] to mitigate the potential for significant stranded inventory in this subsector."
Final comments on this rule were received before July 26, 2024. As you can see, there were growing concerns about stranded inventory, which helped predicate this proposed rule.
We will update you on the developments regarding this proposed rulemaking and if/when it is finalized.
