Yes, R-22 (Freon) is still available for servicing older HVAC and refrigeration units, but it can no longer be manufactured or imported in the U.S. Today, technicians rely entirely on recycled, reclaimed, and existing stockpiled supplies, which makes it very expensive.
No, the general public cannot buy R-22 refrigerant. Under Environmental Protection Agency (EPA) regulations, you must be a licensed, EPA-certified HVAC professional to legally purchase and handle R-22.
A pound of R-22 refrigerant typically costs between $90 and $250 per pound installed, with an average of around $150 per pound. Total costs vary based on your location and the amount your specific system needs.
If you are asking about a brand new R-22 air conditioning unit, they are no longer manufactured, as the production and importation of new R-22 and R-22 systems have been illegal in the U.S. since 2020. However, if you are looking to buy brand new (virgin) R-22 refrigerant to service an existing system, it costs between $90 and $250 per pound.
Legally, no, you cannot refill an R-22 system yourself. Under EPA regulations, purchasing and handling restricted refrigerants like R-22 requires an EPA Section 608 Certification. Attempting to do so without a license can result in severe federal fines.
A 30 lb cylinder of R-22 refrigerant is typically worth between $500 and $800 at wholesale. However, if you are buying it from an HVAC supply house or having a technician recharge your system, the retail cost to get and install it can range from $2,700 to $4,500 ($90 to $150+ per pound).
The best, most practical drop-in substitutes for R-22 are R-407C, R-421A, and R-438A (Freon MO99). These are zero-ozone-depleting blends that closely match the pressures and capacities of R-22 without requiring a full system replacement.
Yes, you can still buy R-12 (Freon), but it is very expensive and its sale is tightly regulated. Because R-12 is an ozone-depleting substance, its production was banned in the 1990s. Today, supplies rely on recycled and stockpiled refrigerant.
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.
Adding refrigerant to your central A/C system isn't something you should need to do regularly. In fact, a properly functioning system is designed to run efficiently without requiring frequent refills. On average, most central air conditioning systems need to have the refrigerant replaced ever two to five years.
Expect to pay $100 to $250 per pound for R-22 refrigerant when having an HVAC technician recharge your system. Because R-22 was phased out and its production completely stopped, supplies are dwindling, making it one of the most expensive refrigerants on the market.
The HVAC industry is fully transitioning to next-generation A2L refrigerants, primarily R-454B and R-32. Driven by federal environmental mandates, these replacements drastically reduce the carbon footprint compared to older HFC types.
Comstar RS-44b is the closest, market available drop-in replacement for R22 that requires no oil changes and no system changes.
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.
In the U.S., it is generally illegal to refill your home air conditioner's refrigerant yourself. Under EPA regulations, you must possess a Section 608 Technician Certification to purchase and handle refrigerants like R-410A or R-22.
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, MO99 (R-438A) is widely considered a good and highly convenient replacement for R-22. However, weighing its pros and cons is essential:
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.
You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force. You can convert your current system to one that runs on R-410A, but the cost will be high.
Legally, no, you cannot refill an R-22 system yourself. Under EPA regulations, purchasing and handling restricted refrigerants like R-22 requires an EPA Section 608 Certification. Attempting to do so without a license can result in severe federal fines.
If you are asking about a brand new R-22 air conditioning unit, they are no longer manufactured, as the production and importation of new R-22 and R-22 systems have been illegal in the U.S. since 2020. However, if you are looking to buy brand new (virgin) R-22 refrigerant to service an existing system, it costs between $90 and $250 per pound.
The $5,000 rule is a quick formula used to decide whether to repair or replace an aging HVAC system. It helps homeowners avoid the trap of continuously pouring money into old equipment that is nearing the end of its lifespan.
