If you own an older home air conditioner or heat pump, you may have heard that R-22 — the refrigerant many people still call “Freon” — is no longer produced. That raises understandable questions: is your system now illegal, can it still be repaired, and what replaces R-22? This guide explains where things stand and what your realistic options are.

Is R-22 still legal to use?

Yes — your existing R-22 system is legal to own, operate, and repair. What ended was production and import of new R-22, which the EPA halted at the start of 2020 because R-22 is an ozone-depleting substance. The refrigerant itself was not banned from use. Existing systems can continue running and can still be serviced using recovered, recycled, and reclaimed R-22 for years to come.

The practical catch is supply and cost. With no new R-22 entering the market, the available pool only shrinks, and prices have climbed steadily. A significant repair that requires several pounds of R-22 can become expensive enough that replacing the equipment makes more financial sense.

Why was R-22 phased out?

R-22 is a hydrochlorofluorocarbon (HCFC). The chlorine it contains damages the ozone layer, which is why it was scheduled for phase-out under the Montreal Protocol. Its replacement in most systems built after the mid-2000s was R-410A, an HFC blend with zero ozone-depletion potential. Ironically, R-410A turned out to have a very high global warming potential, so it is now being phased down in turn — more on that below.

What can I use to replace R-22?

There are two realistic paths, and the right one depends on your equipment’s age and condition:

• Keep servicing with reclaimed R-22. If your system is otherwise sound, topping it up with reclaimed R-22 after a leak repair is legal and often the cheapest short-term fix. Only an EPA Section 608 certified technician can purchase the refrigerant and perform the work.
• Replace the system. For aging equipment facing a costly repair, a new system using a modern low-GWP refrigerant (R-454B or R-32) is usually the better long-term investment. These deliver comparable cooling with far lower environmental impact and stronger regulatory support going forward.

A word of caution on “drop-in” replacement refrigerants marketed for R-22 systems: these require an EPA-certified technician to evaluate compatibility, may affect performance, and can complicate warranty coverage. They are not a simple do-it-yourself swap.

Do I have to replace my R-22 air conditioner?

No. There is no legal requirement to remove or replace a working R-22 system. The decision is purely economic: as R-22 prices rise and older equipment loses efficiency, at some point the cost of repairs and refrigerant outweighs the cost of a new, more efficient unit. Many homeowners choose to replace proactively rather than face an expensive R-22 recharge on a system already near the end of its service life.

Is R-22 the same as Freon?

“Freon” is a brand name, not a specific refrigerant. It was long used as a genericized term for R-22 in home cooling, which is why the two are often treated as synonyms. Strictly speaking, Freon-branded products have included several different refrigerants over the years, but when most people say their home AC “needs Freon,” they mean R-22.

Tools for servicing R-22 and modern systems

R-22 refrigerant itself can only be bought by certified technicians, but if you’re a qualified pro servicing these systems, we carry the gauges and equipment you need — including the Mastercool manifold gauge set rated for R-22, R-404A and R-410A, plus vacuum pumps and recovery hose sets for evacuating and charging systems correctly.
