Is R-22 Still Available? What You Can Legally Do With It

Yes — but only as reclaimed, recovered or pre-2020 stock. Production and import of virgin HCFC-22 ended on January 1, 2020. Using R-22 to service existing equipment was never banned and still is not, and EPA says those systems may be serviced "for as long as necessary." Only a certified technician may buy it.

Search this and you get homeowner marketing pages, a Reddit thread and a dozen contractor blogs, most of which blur "no longer produced" into "illegal." Those are not the same thing, and the difference decides whether you top up a twenty-year-old condenser or condemn it. Here is what the regulation actually says.

Is R-22 banned?

No. Nothing in the rules prohibits using R-22, servicing an R-22 appliance, or owning one.

What ended was supply of new material. R-22 is a class II ozone-depleting substance under Clean Air Act Title VI, phased out on a schedule in 40 CFR Part 82, Subpart A. As of January 1, 2020, no virgin HCFC-22 may be produced in or imported into the United States, with narrow exceptions for export and for feedstock use. EPA's own position on the equipment side is that HCFC-22 "may continue to be used to service existing systems for as long as necessary" (EPA).

This is the same confusion that surrounds the newer HFC rules. If you have read about the R-410A phase-out, it is the identical pattern one refrigerant generation later: the restriction lands on manufacture and import, not on service.

Question	Answer
Can virgin R-22 be produced or imported?	No, not since January 1, 2020
Can you service an existing R-22 system?	Yes, indefinitely
Can you buy R-22?	Yes, if you hold a Section 608 card
Can a homeowner buy R-22?	No — stationary refrigerant sales are restricted to certified technicians
Must an R-22 system be retrofitted or replaced?	No requirement exists
Can used R-22 be sold to a new owner?	Only if reclaimed by an EPA-certified reclaimer

Where does R-22 still come from?

Three sources, and all three are legal.

Reclaimed refrigerant. Recovered R-22 sent to an EPA-certified reclaimer, cleaned back to the AHRI 700 purity specification and resold. This is the bulk of the market now.

Pre-2020 virgin stock. Material produced or imported before the cut-off is legal to sell and use until it runs out. Some still sits in distribution.

Refrigerant you recovered yourself. You may recover R-22 from one system and put it back into a system belonging to the same owner without reclaiming it. What you may not do is sell recovered refrigerant to a new owner for use as a refrigerant unless a certified reclaimer has processed it first — that prohibition lives in 40 CFR 82.154 (eCFR).

That last distinction catches people out. Pulling 20 pounds out of a condemned unit and putting it into the same customer's second system is fine. Selling it to the shop across town is not.

Can a homeowner buy R-22?

No. The refrigerant sales restriction at 40 CFR 82.154(c) allows the sale of refrigerant for use in stationary refrigeration and air conditioning equipment only to a certified technician or to someone who employs one, and it puts the burden of verifying that on the seller (EPA).

There is one exception and it is not a residential one: small cans of two pounds or less with self-sealing valves may be sold uncertified for motor vehicle air conditioning. That covers a can of R-134a for a car. It does not cover a home system.

So the answer to the most common version of this search — "where can I buy R-22 for my house" — is that you cannot. A certified technician can, which is the practical reason the card matters if you do this work for a living. Most residential and light commercial R-22 equipment is high-pressure, so it falls under Type II; the Type II practice test is where to check whether you are ready.

Does Section 608 treat R-22 differently from R-410A?

Barely. Your duties on an R-22 job are the duties you have on any job.

Venting is prohibited. Under Clean Air Act section 608(c) and 40 CFR 82.154(a), you may not knowingly release refrigerant while maintaining, servicing, repairing or disposing of an appliance. R-22's ozone-depleting status changes the environmental stakes, not the rule you follow.

Recovery levels come from the appliance, not the refrigerant. Table 1 of 82.156 sets the vacuum you must reach before opening a system, and it is keyed to pressure class, charge size and when your recovery machine was built. A high-pressure appliance under 200 pounds — nearly all R-22 residential work — requires 0 inches of mercury. Full detail is in what Section 608 actually requires when you recover refrigerant.

The November 15, 1993 date is about your machine. It appears in Table 1 as the manufacture date of the recovery equipment, and it has nothing to do with how old the R-22 system in front of you is. Plenty of published material gets this backwards, and it is a favorite exam trap precisely because it is so widely misreported.

Leak repair may apply. For appliances with a full charge of 50 pounds or more, 82.157 sets annual leak rate thresholds that trigger a repair obligation — 30% for industrial process refrigeration, 20% for commercial refrigeration, and 10% for comfort cooling and all other appliances. A residential split system is far below the 50-pound trigger. A supermarket rack running R-22 is not.

Retrofit or replace?

Once R-22 price becomes the deciding factor, customers start asking about conversion. Nothing in the regulation requires it, and nothing forbids it. What governs a retrofit is EPA's SNAP program, which lists substitutes as acceptable for specific end uses, plus the equipment manufacturer's instructions.

The marketing term "drop-in" does not describe anything you will actually meet on a truck. Every R-22 conversion involves at least these decisions:

Consideration	Why it bites
Oil	R-22 systems run mineral oil. R-407C needs POE, so the oil must be changed out. Some service blends are formulated to circulate with existing mineral oil — follow the manufacturer, not a forum
Capacity	Substitutes rarely match R-22 tonnage exactly. Expect a capacity change and size metering accordingly
Pressures and glide	Zeotropic blends have temperature glide, so you charge as liquid and read saturation differently than with single-component R-22
Components	Metering device, driers and seals may need replacing. Mixing refrigerants in one system is never acceptable
Labeling	A retrofitted system must be labeled for the refrigerant and oil it now contains, or the next technician charges it wrong

None of that is a Section 608 requirement — it is manufacturer guidance and competent practice, and the honest comparison is usually retrofit cost against a new system with a decade of life. If the difference between a single-component refrigerant and a blend is not solid ground for you yet, the classes of refrigerant worth knowing covers it.

What this means on the job

Three sentences cover most of it. R-22 is legal to use and always has been. It is only legal to buy if you hold a card. Nobody can force your customer to replace a working system.

The pressure you feel on R-22 work is economic. A capped supply that only shrinks means the cylinder price keeps climbing, which changes the arithmetic on every judgment call: a slow leak that was once worth topping up becomes worth finding, recovery stops being a chore and starts being inventory, and a 20-year-old unit with a failed compressor is usually a replacement conversation rather than a repair one.

What has not changed is the compliance side. Do not vent it, recover it before you open the system, hit the Table 1 level for your machine and the appliance, keep the records, and do not sell recovered refrigerant to a new owner. Those obligations look exactly the same as they do on an R-410A or R-454B system, which is the point — Section 608 follows the appliance and the technician, not the chemical.

Frequently asked questions

What refrigerant can I substitute for R-22?

It depends on the equipment and the manufacturer's guidance. R-407C and several service blends are listed as acceptable substitutes for various end uses under EPA's SNAP program. None is a true drop-in: expect to address oil type, capacity change, temperature glide, metering device and labeling on any conversion.

Can you still get R-22 in 2026?

Yes. No virgin R-22 has been produced or imported since January 1, 2020, but reclaimed R-22 processed by EPA-certified reclaimers and remaining pre-2020 stock are both legal to buy and use. Availability is a price question rather than a legal one, and the price has risen steadily.

Is it illegal to add R-22 to a leaking system?

For most residential equipment, no rule prohibits topping up. The leak repair requirements in 40 CFR 82.157 apply to appliances with a full charge of 50 pounds or more, where exceeding the annual leak rate threshold for that appliance type triggers a repair obligation. Venting during the work is always prohibited.

Do I need a special certification to work on R-22?

No. Section 608 certification is set by appliance class, not refrigerant. A Type II card covers high-pressure appliances whether they hold R-22 or R-410A, Type I covers small appliances, and Type III covers low-pressure. There is no separate R-22 credential, and Section 608 certification does not expire.

Can I put recovered R-22 back into a customer's system?

Yes, into equipment belonging to the same owner, which is why on-site recovery is worth doing properly. Selling recovered refrigerant to a different owner for use as a refrigerant requires that an EPA-certified reclaimer process it to the AHRI 700 specification first.
