EPA Temporarily Eases R-410A Installation Ban Amid Industry Concerns
Contractors and distributors granted reprieve as EPA deprioritizes enforcement of upcoming R-410A installation restrictions.

The Environmental Protection Agency (EPA) has granted temporary enforcement relief for contractors and distributors installing R-410A residential and light commercial air conditioning systems.
Although the official January 1, 2026 ban on these installations remains, the EPA clarified it will not make federal enforcement a priority as it reconsiders the Technology Transitions (TT) rule.
This move eases concerns over unsellable inventory, but state and local regulations may still apply.
New York, for example, requires contractors to continue following stricter state rules, regardless of the EPA’s stance.
The ruling does not affect Variable Refrigerant Flow (VRF) systems, which keep their strict deadlines.
Contractors should continue documenting installation details, monitor state regulations closely, and start preparing for the shift to A2L refrigerants before updated EPA guidance arrives in early 2026.
This relief is temporary — proactive planning remains crucial for ongoing compliance.
