Yes, you can buy R-22 (Freon), but it is heavily restricted. Under EPA regulations, you must hold a Section 608 technician certification to legally purchase it. It cannot be legally purchased by the general public.
R22 refrigerant is illegal to import and manufacturer in the U.S. But it's not illegal for anyone to buy R22 freon. And it's not illegal to sell it IF you have a license. As long as the stocks last, you will be able to continue purchasing R22 from specialized dealers and form your air conditioning company.
R-22 refrigerant typically costs between $𝟗𝟎 and $𝟐𝟓𝟎 per pound. Because R-22 has been phased out, the supply is dwindling, which causes prices to continuously climb.
If you're interested in learning how to refill R22 in your air conditioner, it is important to know that this is not something a homeowner can do on their own. Due to complexity, safety concerns, training and licensing required we do not recommend doing this without having a trained professional onsite.
The "best" R22 replacement depends on whether you are doing a drop-in retrofit (using existing equipment) or upgrading the whole system. For retrofits, the top choices are R407C for maximum efficiency and R422D for easier compatibility. For long-term viability, replacing the system entirely with an R454B or R32 system is recommended.
New production and importation of R-22 (Freon) were banned in the U.S. in 2020. Today, only recycled or reclaimed R-22 is legally available. You can continue to use existing equipment, but supplies of recycled R-22 are steadily dwindling, and it will eventually become entirely unavailable or prohibitively expensive.
The best replacement for R-22 depends on your system's configuration. Because R-22 is fully phased out, the most common drop-in substitutes are R-438A (MO99), R-407C, and RS-44b (R-453A). These allow for system retrofits, though complete system replacement is often recommended for aging units.
Refrigerant can only be sold to technicians certified under the Section 608 or Section 609 technician certification programs, where individuals may only purchase refrigerant consistent with the appliances covered by their certification.
Whether you flip an R22 tank upside down depends entirely on what you are trying to do with the system. Because R22 is a single-component refrigerant (not a blended mix like R410A), it can safely be dispensed as either a liquid or a vapor.
A 30-pound cylinder of R-22 refrigerant is generally worth between $500 and $1,200 to purchase wholesale, and up to $2,400 to $4,500 if bought directly from a service company during a home repair.
R-22 is extremely expensive because it has been legally phased out. Driven by federal environmental regulations, skyrocketing supply chain costs, and contractor labor rates, prices range from $100 to $300+ per pound, meaning a standard refill can cost between $800 and $2,000+.
Mixing refrigerants is always a no-no. Drop-ins aren't so great either. R-22 air conditioning systems are headed to the dustbin of HVAC history. If your old AC has a refrigerant leak and your warranty has expired, the best thing to do is invest in a new system and a professional installation.
Do I need a license to buy R22 refrigerant? Yes. Only EPA Section 608 certified technicians can legally purchase and handle R22.
Since Freon MO99 is the closest capacity match to R-22, compared with most of the other no-oil change refrigerants, it will reach the desired set point before other, lower-capacity refrigerants. With Freon MO99, residents are unlikely to know a different refrigerant is even being used.
A2L refrigerants, the new refrigerants for 2026, will replace R-410A in new systems. A lot about A2L refrigerants is explained in their name: The “A” means low toxicity. The “2L” is a safety classification, indicating it is mildly flammable.
Yes, you can buy R-22 refrigerant online. However, because the production and import of R-22 are banned in the U.S. and strictly limited to reclaimed and recycled supplies, it is extremely expensive and legally requires a valid EPA Section 608 certification to purchase.
Yes, AutoZone sells refrigerant. While "Freon" is a brand name typically referring to R-12 (which is banned in modern vehicles), they carry its standard replacements: R-134a and R-1234yf.
No, you cannot legally buy R-22 with a Section 609 certification.
R-22 refrigerant typically costs between $𝟗𝟎 and $𝟐𝟓𝟎 per pound. Because R-22 has been phased out, the supply is dwindling, which causes prices to continuously climb.
Yes, MO99 (also known as R-438A) is a direct, "no-oil-change" drop-in replacement for R-22. It is specifically engineered to replace R-22 in residential and commercial air conditioning, heat pumps, and refrigeration systems.
No, you should not put R-134a into an R-22 system. Mixing them or using R-134a as a direct drop-in is dangerous and will likely destroy your system.
A 30-pound cylinder of R-22 refrigerant is generally worth between $500 and $1,200 to purchase wholesale, and up to $2,400 to $4,500 if bought directly from a service company during a home repair.

In 2025, R-22 costs between $90 and $250 per pound, with the average price around $125 per pound. Since most home systems need 6 to 12 pounds, a full recharge—including labor—can cost $660 to $1,900. And prices will only keep climbing.
