The R-410A phase-out, explained
Since January 1, 2025, no new R-410A systems are manufactured — but your existing AC stays legal, serviceable, and yours. Nobody is coming for it. What changes is the economics of refrigerant-touching repairs. This is a production phase-down, like R-22 before it, not a ban on owning your system.
What did NOT change
- Your R-410A system is still legal to run
- It can still be serviced and repaired
- Refrigerant is still available for it
- No requirement to replace anything
What DID change
- No new R-410A equipment is built
- R-410A price per pound is climbing
- New systems use R-454B or R-32
- Refrigerant-heavy repairs cost more
What the AIM Act did
The 2020 AIM Act tells the EPA to phase down high global-warming-potential refrigerants. R-410A has a GWP around 2,088, which put it on the list. Here's the timeline, in homeowner terms:
| When | What happens | What it means for you |
|---|---|---|
| 2020 | AIM Act signed | Congress directs the EPA to phase down high-GWP HFC refrigerants like R-410A. |
| 2023 | Allocation cuts begin | Production quotas start tightening; prices begin their climb. |
| Jan 1 2025 | Manufacturing stop | No new R-410A systems are built or imported — the change most people heard about. |
| 2026+ | Supply tightens | Existing R-410A stays available for service, but the price curve keeps rising. |
| ~2036 | 85% production cut | The long tail of the phasedown; reclaimed refrigerant carries older systems. |
If you own an R-410A system
Keep running it and keep servicing it — parts are fine and refrigerant is available. What's shifted is the price curve: R-410A now runs roughly $50–$100 per pound installed and rising. That changes leak urgency. A slow leak you'd have tolerated in 2020 now quietly bleeds money, so the leak-fix-first rule matters more than ever, and good maintenance that preserves the charge pays off.
We've seen this movie: R-22 went from about $10 a pound to $150 over its phasedown. Same arc, different refrigerant.
The repair-or-replace math just changed — for one repair class
The phase-out only flips the decision on refrigerant-touching repairs — a coil, a compressor, a major leak — on an aging system. Non-refrigerant repairs (a capacitor, a fan motor, a board) are unchanged. Here's the difference on a 12-year unit:
Coil replacement ......... $1,200
R-410A to recharge ....... $600 (and rising each season)
Combined .............. $1,800 into a 12-yr system
// vs a new system on current refrigerant, rebate-eligible.
// The refrigerant cost is what tips it → lean replace
Run the full framework on the keystone: repair or replace. Coil brackets are on AC repair cost.
R-454B vs R-32 — and the brand camps
New equipment ships on one of two lower-GWP refrigerants. Both are classed A2L — mildly flammable — which is why new systems include leak sensors and updated airflow hardware. In an installed system, the real-world risk is comparable to before; it's neither nothing nor cause for alarm.
| Refrigerant | GWP | Brand camp |
|---|---|---|
| R-454B | ~466 | Carrier, Bryant, Trane |
| R-32 | ~675 | Daikin, Goodman |
| R-410A (old) | ~2,088 | No longer in new equipment |
Both successors are far lower GWP than R-410A. Service networks are maturing on both.
Can you convert an R-410A system to a new refrigerant?
No — and every honest technician will tell you so. The oils, operating pressures, and compressor specs don't cross over between refrigerants. Anyone pitching a "drop-in replacement" for your R-410A system is a red flag. What is legitimate is servicing your existing system with reclaimed R-410A from the recovery market.
Should you replace now or hold?
Lean toward now
Your system is already dying, or it needs a refrigerant-heavy repair that's turning into a money pit. Replacing onto new refrigerant ends the R-410A price exposure.
Lean toward waiting
Your system is healthy. New-refrigerant equipment prices are still settling, and state and utility rebates can improve the math if you time it. (The federal 25C tax credit expired at the end of 2025.)

Common questions
Will refrigerant run out for my system?
No. R-410A is still produced for servicing, and a reclaimed-refrigerant market recovers and resells it. Your system stays serviceable — the change is price, not availability.
How much more do new systems cost now?
New equipment on the successor refrigerants runs roughly 15–20% more than the old R-410A equipment did, reflecting the new refrigerant and the added safety hardware. Rebates can offset a good chunk of that.
Does the phase-out affect heat pumps too?
Yes. Heat pumps use the same refrigerants as air conditioners, so new heat pumps ship with R-454B or R-32 just as new ACs do.
What about window units?
Smaller self-contained units, including many window and portable ACs, have been moving to R-32 for a while, so that transition is largely already underway.
