Is Freon Being Phased Out? R-410A, R-454B & What It Means (2026)

Is Freon being phased out?

Yes. R-22 - the refrigerant commonly called Freon - was banned from production and import in the United States on January 1, 2020. And as of January 1, 2025, new air conditioners and heat pumps can no longer be manufactured with R-410A (Puron); they now use lower-global-warming refrigerants like R-454B or R-32 under the federal AIM Act. If you own an older system, this affects what it costs to repair and when it makes sense to replace.

Here's a plain-English timeline and what to do about it.

Quick takeaways:

• R-22 ("Freon") has been banned from new production since 2020
• Existing R-22 systems still work, but recharging one is now expensive
• R-410A new-equipment production ended in 2025 under the AIM Act
• New 2025+ systems use R-454B or R-32 (lower-GWP refrigerants)
• An old R-22 system that needs refrigerant is usually a replace, not recharge decision

The refrigerant phase-out timeline

Both phase-outs come from environmental law: R-22 damaged the ozone layer (Montreal Protocol), and R-410A, while ozone-safe, is a potent greenhouse gas being phased down under the AIM Act.

What it means if you have an R-22 system

If your AC is roughly 15+ years old, it likely uses R-22. It will keep running, but because R-22 can no longer be produced, the only supply is reclaimed or stockpiled - and prices have climbed sharply. A refrigerant leak on an R-22 system can mean hundreds of dollars just for the recharge, and that money is spent on aging equipment that will need it again.

For most homeowners, an R-22 system that develops a leak is a replacement decision, not a recharge. A modern system also runs far more efficiently, so the new unit starts paying you back on day one. Our repair vs. replacement guide covers how to weigh it.

What it means if you have an R-410A system

R-410A (Puron) systems - installed roughly 2010 through 2024 - are completely fine to keep and service. R-410A is still available for repairs and will be for years; it's only new equipment manufacturing that moved to the newer refrigerants in 2025. You don't need to rush to replace a healthy R-410A system. Just know that as the phase-down continues, R-410A prices will gradually rise, the same way R-22's did.

What about new systems (2025 and later)?

New air conditioners and heat pumps now ship with R-454B or R-32. For you as a homeowner, the day-to-day experience is identical - same cooling, same controls. The refrigerants are simply more climate-friendly and slightly more efficient. The one practical note: these are mildly flammable (A2L class), so they require technicians trained and equipped for them, which any reputable installer already is.

Should you replace your old system now?

You don't have to replace a working system because of the phase-out alone. But replacement makes clear sense when:

• Your system uses R-22 and develops a refrigerant leak
• The unit is 12+ years old and facing a major repair
• You're paying repeatedly for recharges (a leak only gets worse)
• Your energy bills are climbing as the old unit loses efficiency

See how long an AC lasts and what a new system costs to plan ahead rather than getting caught by a mid-summer failure.

Bottom line

Freon (R-22) has been phased out since 2020, and R-410A new-equipment production ended in 2025 in favor of R-454B and R-32. A healthy R-410A system is fine to keep; an aging R-22 system that needs refrigerant is usually better replaced than recharged. When in doubt, have a licensed tech identify your refrigerant and price both paths.
