EPA is reconsidering its Technology Transitions Rule, including the January 1, 2026, installation deadline for R-410A systems in residential and light commercial applications. The agency’s proposal, which currently leaves out VRF and VRV equipment, acknowledges the deadline should be removed, but until the rule is finalized, it technically stands — leaving contractors in limbo. With reconsideration underway and no enforcement guidance issued, the industry is left guessing how EPA will treat existing inventory until final action is taken.
This uncertainty isn’t theoretical. According to industry estimates, stranded R-410A inventory could exceed $500 million. Without clear enforcement direction, contractors are being forced to make business decisions without knowing where the compliance lines are.
ACCA is seeking clarity from EPA during the reconsideration period — and EPA has the authority to provide it. The agency can confirm it will exercise enforcement discretion and not pursue actions against contractors installing R-410A systems that were legally manufactured or imported under prior rules.
This guidance would:
- Prevent unnecessarily stranded inventory
- Reduce confusion across the industry
- Support a more orderly refrigerant transition
- Ensure contractors aren’t penalized for installing compliant R-410A systems
Why your voice matters
EPA needs to hear directly from contractors who shoulder this uncertainty. Clear enforcement guidance now would give ACCA members the clarity they need to plan responsibly, serve customers, and keep projects moving while EPA completes its work. Please take a moment to participate in our action alert and urge EPA to provide that clarity.
Take action and ask EPA to clarify enforcement for R-410A during reconsideration.
