The One-Paragraph Version Of The Law
The AIM Act of 2020 directs a step-down of high-global-warming HFC refrigerants. Its key residential milestone arrived January 1, 2025: new split-system AC and heat pump equipment must use refrigerants under a 700 GWP threshold. The industry answered with R-454B (most brands) and R-32 (Daikin family). A sell-through window let distributors finish moving previously manufactured R-410A equipment during the transition.
Who The Rules Touch — And Who They Don't
Touched: anyone buying new equipment (it arrives with the new refrigerant automatically) and, slowly, anyone recharging legacy systems as quotas tighten supply. Untouched: every working R-410A and R-22 system in Florida, which may be serviced for as long as parts and economics allow. There is no compliance action, deadline, or retrofit requirement for homeowners.
A2L, Demystified
The new refrigerants carry an A2L safety classification — lower toxicity, mildly flammable under narrow conditions. Equipment standards answered with refrigerant leak sensors, revised airflow logic, and updated installation codes; technician training covers A2L-specific handling. In practice, A2L systems install and run like any other modern AC.
What Florida Quotes Look Like Under The Rules
New-install quotes now name R-454B or R-32 and reflect early-cycle equipment pricing. Repair quotes on existing systems should itemize legacy refrigerant by type, pounds, and rate. Two red flags worth knowing: "must replace because R-410A is banned" (false), and new-equipment quotes that do not specify the refrigerant at all (sloppy at best).
Florida Timing Considerations
Broward's near-year-round cooling season means refrigerant economics bite here first: leaks surface sooner, recharges recur faster, and the price drift on R-410A compounds across more runtime hours. It also means replacement upgrades pay back faster — SEER2 gains compound across those same hours.
The Sensible Homeowner Playbook
Working system: maintain it, fix leaks properly, ignore the noise. Aging system facing a refrigerant-side repair: run the $5,000 rule with a thumb on the replacement side. Buying new: confirm the refrigerant, compare SEER2 tiers, and make sure the quote itemizes permits. Pressured by a transition-themed pitch: free second opinion, every time.
The Refrigerant Timeline At A Glance
Three refrigerant generations now coexist in Florida homes.
| Refrigerant | Era | Status in 2026 |
|---|---|---|
| R-22 (Freon) | Pre-2010 systems | Production banned 2020; reclaimed-only, premium priced; systems 16+ years old. |
| R-410A (Puron) | ~2010-2024 systems | Servicing fully legal; supply phasing down; the mainstream of existing Broward systems. |
| R-454B / R-32 | 2025+ systems | Required for new residential equipment; A2L class with updated safety standards. |
Know Where You Stand In Five Minutes
- Read the outdoor data plate: which refrigerant generation do you own?
- Note the system's manufacture year (also on the plate).
- If R-22: start replacement planning on your schedule, not a breakdown's.
- If R-410A: business as usual — maintain, and fix leaks the first time.
- If buying new: the quote should name R-454B or R-32, a SEER2 tier, and permits.

Schedule ServiceFAQs
Do the new rules apply to mini splits and heat pumps?
Yes — all new residential air conditioning and heat pump equipment, ducted or ductless, falls under the same GWP limits and uses the new refrigerants.
Can a contractor still install a new R-410A system in 2026?
Only from limited remaining sell-through inventory of equipment manufactured before the deadline, and that window has largely closed. New production is all R-454B/R-32.
Are the new refrigerants less effective in Florida heat?
No. R-454B and R-32 perform comparably or better, and the equipment designed around them meets stricter SEER2 efficiency floors than the gear it replaces.
Will my homeowner's insurance care about my refrigerant?
No Florida policy or 4-point inspection standard evaluates refrigerant type. Inspectors care about system age, condition, and visible issues.
What happens to recovered R-410A from replaced systems?
Certified technicians recover it for reclamation — cleaned and resold to service the existing fleet. That reclamation stream is a core part of how legacy servicing stays viable through the phase-down.
Where can I verify any of this?
