June 2024 – U.S. EPA publishes proposed one-year sell-through extension for VRF systems
As anticipated, the EPA plans on providing a one-year sell-through extension for VRF systems, similar to the one-year sell-through extension already in place for mini/multi-splits and other air-conditioners and heat pumps. As a result, VRF systems using R-410a can be installed through 2026, so long as they were manufactured in the U.S. or imported into the U.S. prior to 1/1/2026. This rule is out for proposals with a 30-day public comment period but is expected to be put in place as-is.

The phase-out of R-410a in new VRF systems will therefore mimic that of mini/multi splits and other air-conditioners and heat pumps, other than both the “manufacture/import by date” and the “install by” date being one year later. Below is an overview of the different deadlines, assuming this latest ruling is published as-is.
