To legally buy R-22 refrigerant, you must hold an EPA Section 608 Technician Certification. Sellers will verify your license before processing orders. Expect to pay between $ 100 and $ 200 + per pound, or $ 350 to $ 600 + for a 30 lb cylinder.
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.
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.
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.
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.
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.
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.
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+.
As a homeowner, you cannot legally purchase or handle Freon (or other AC refrigerants) for a home system without an EPA Section 608 Technician Certification. The Environmental Protection Agency heavily regulates these substances under the Clean Air Act.
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.
Installing an AC unit isn't just a technical job. It's a legal one, too. Most municipalities require permits for HVAC work, and failing to obtain them can result in fines or forced removal. You'll also need to follow strict building codes and EPA regulations, especially when handling refrigerants.
Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22. The benefits of Freon MO99 include: Capacity — The ability of Freon MO99 to heat or cool a given space is closer to Freon R-22 than any other refrigerant on the market.
Yes, R-12 refrigerant is still legally available. While its manufacture was banned decades ago, you can still purchase existing and reclaimed supplies.
No, you should never intentionally mix R-22 and MO99 (R-438A).
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 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.
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.
While marketing often claims certain products are "drop-in" replacements, there are no true, zero-effort "drop-in" replacements for R-22 that maintain identical performance without any modifications. Retrofitting requires careful, professional procedures, including changing oil types or replacing components to ensure system longevity and efficiency.
You cannot legally or safely recharge a central home AC unit yourself. DIY refrigerant kits are strictly intended for car AC systems, not home HVAC. Handling refrigerants requires an EPA Section 608 certification.
Black Death occurs when moisture contamination in an AC system forms corrosive acids that attack metal surfaces and break down compressor oil, resulting in a dark sludge that can damage components. It is caused by humidity entering through small leaks or using improper refrigerant.
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.
As of January 1, 2020, the United States banned the use of the R22 refrigerant, commonly known as Freon.
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.
