Airo Service on the EPA R-410A Rule Change: What "Legal Again" Leftover Systems Mean for Florida Buyers

FORT LAUDERDALE, Fla. — November 10, 2026

Airo Service is advising South Florida homeowners to look closely at discounted air conditioners built for R-410A refrigerant, after a federal rule change made it legal again to install some of that leftover equipment.

What changed

Under an EPA final rule published on May 26, 2026 and effective July 27, 2026, split air conditioning systems manufactured or imported before January 1, 2025 that use R-410A may be installed in homes until existing supplies are depleted. The earlier cutoff on installing those systems no longer applies. Manufacturers still stopped building new R-410A residential equipment at the start of 2025, and R-410A production continues to step down.

What buyers should ask

• How old is the equipment, and how long has it been in storage?
• What refrigerant will repairs need in five or ten years, and what will it cost then?
• Is the warranty registered and complete for stored stock?
• Can the price difference cover that future refrigerant risk?

“A leftover R-410A system can be a fair deal if the price reflects what it is. What we tell people is simple: an R-410A system cannot be converted to the new refrigerants later, so you are buying into a refrigerant that only gets scarcer. Get both quotes on paper and compare them honestly.” said Roman Shatokhin, Founder of Airo Service.
