EPA Removes R-410A Installation Deadline in Final Rule

The Environmental Protection Agency announced on May 21 that contractors can continue installing existing R-410A HVAC equipment with no federal deadline. The agency's amended final rule revises the 2023 Technology Transitions Rule, eliminating the previous installation cutoff date. No new R-410A systems are being manufactured, so available inventory will eventually deplete naturally. The EPA projects the combined rule changes will deliver over $2.4 billion in savings across the industry.
This gives contractors legal cover to install remaining R-410A stock during the transition to A2L refrigerants.
Check your current R-410A inventory levels. Confirm your distributor's remaining stock to plan installations while supply lasts.
Key Takeaways:
- EPA removed installation deadline for existing R-410A equipment inventory
- No new R-410A systems manufactured, so supply will run out naturally
- Combined rule changes expected to save industry over $2.4 billion
