1. Governing rule & phase-down
   The 410A transition in residential and light commercial air conditioning/heat pumps is governed by EPA’s Technology Transitions program under the American Innovation and Manufacturing (AIM) Act.

2. New 410A systems – how long can we install them?
   On EPA’s “Technology Transitions HFC Restrictions by Sector” page, note 6 under the Systems table states:
   “New systems with a GWP above 700 can be installed until January 1, 2026, so long as all components are manufactured or imported prior to January 1, 2025.” Technology Transitions HFC Restricitons by Sector »
   Since R-410A has a GWP far above 700, our remaining residential/light-commercial split and packaged systems that were manufactured/imported before 1/1/2025 are explicitly allowed to be installed as new systems through 12/31/2025 under current EPA rules.
3. Use and service of 410A systems
   In the same final rule, EPA is clear that the regulation “does not restrict the continued use of any existing products or RACHP systems” and that systems may be serviced and repaired throughout their useful life, with components for repairs still allowed to be produced/imported/sold.

   In other words, customers who choose a 410A system are buying legal equipment that can be serviced for years, not something that becomes unusable when the new A2L systems take over the market.
4. Proposed changes (for awareness)
   In late 2025, EPA proposed revisions to parts of this rule, including potentially removing the Jan 1, 2026 installation deadline for some residential/light-commercial systems built from pre-2025 components, but those changes are not final yet. Reconsideration Proposals Factsheet »
   Until a new final rule is published, our conservative compliance position remains:
   • Only install 410A systems where all components are pre-1/1/2025 manufacture/import, and
   • Treat Jan 1, 2026 as the install cutoff for new 410A systems.

• There is no EPA rule banning the sale or use of R-410A refrigerant for servicing existing systems — it remains legal to buy and use as long as supply exists.
• EPA’s AIM Act authority and allowance system reduces production and import each year, but doesn’t abruptly make refrigerant illegal at a specific future date like 2026. HFC Allowances »

• After January 1, 2025, new R-410A systems cannot be manufactured or imported for new equipment (except under narrow allowances under other subsectors). Technology Transitions HFC Restrictions Sector »

• The EPA’s Technology Transitions rule currently has a January 1, 2026 installation deadline for new systems built from pre-2025 components. Technology Transitions Final Rule Fact Sheet »
• Note: EPA has proposed removing that install deadline for residential/light commercial HVAC in late 2025, but that proposal is not final yet. EPA Proposes Eliminating HVAC Install Deadline »
