Refrigerants are banned or phased out because they deplete the ozone layer or contribute heavily to climate change. In the U.S., strict regulations—including recent federal policy rollbacks on HVAC requirements—govern the production, import, and use of legacy refrigerants.
Yes, the production and import of R-22 (Freon) are banned in the United States.
Yes, R-12 refrigerant is still legally available. While its manufacture was banned decades ago, you can still purchase existing and reclaimed supplies.
Yes, R32 is not only currently available, but it is the primary EPA-approved replacement for older refrigerants like R410A in new ductless and mini-split air conditioning systems.
January 1, 2025: Manufacturers stopped producing new R-410A residential split systems and heat pumps. Equipment manufactured before this date can still be sold and installed. January 1, 2026: The original deadline for installing R-410A split systems manufactured before 2025.
Short answer: Yes. Eligible R410A systems manufactured before January 1, 2025, can still be installed in 2026 under the Technology Transitions Rule issued by the U.S. Environmental Protection Agency. There is no nationwide ban on the installation of compliant R410A equipment.
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.
No, R-32 is not propane.
R-32 refrigerant typically costs $𝟏𝟐 to $𝟐𝟎 per pound when purchased wholesale. However, if you are having a licensed HVAC technician recharge your system, expect to pay between $𝟓𝟎 and $𝟏𝟓𝟎+ per pound installed, as companies mark up the material and add service or dispatch fees.
Long-Term Risks of Running the Wrong Refrigerant
Running R-410A in an R-454B system stresses the compressor, coils, valves, and piping. These parts aren't rated for the higher pressures, which can lead to premature wear, reduced efficiency, and even sudden failure.
R-12 Freon is highly valued due to a ban on its production, making it expensive for vintage car and machinery maintenance. Expect to pay about $60 to $100 per pound.
No, you cannot put R-134a directly into an R-12 system. Mixing the two refrigerants or their specific oils can cause a chemical reaction, leading to a sludgy, black substance commonly called "Black Death" that will ruin the entire A/C system.
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.
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.
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.
Meaning the phase out of R22 has been planned for almost 30 years. So in summary, it's true, the EPA has mandated that no new “virgin” “HCFC 22” can be manufactured or imported after 2020 due to its effect on the environment.
Getting a license to buy refrigerant is not only a legal requirement but also a professional standard for anyone in the HVAC or automotive service industry. It ensures that refrigerants are handled safely, responsibly, and in compliance with environmental laws.
The $5,000 rule is a guideline to help homeowners decide whether to repair or replace their HVAC system. You multiply the age of your unit by the cost of the needed repair. If that number exceeds $5,000, replacing your HVAC system is often more cost-effective.
Because R-22 is no longer manufactured domestically, whatever supply remains on the market is reclaimed and recycled material, and that limited supply means elevated prices. If an older system develops a leak and needs a significant recharge, the cost of refrigerant alone can make the repair economically questionable.
In the US, you generally cannot buy R-32 refrigerant unless you are a certified HVAC professional. Federal law restricts its sale, and it requires an EPA Section 608 certification to handle or purchase.
The calculating results show that, in the conventional refrigeration cycle (CRC), the mixture R32/R134a has a close performance to that is obtainable with pure refrigerant R22. However, the mixture R32/R134a in the NRC will result in a better performance.
R-32 is classified as an A2L refrigerant, meaning it is mildly flammable. It requires a high concentration of gas in the air and a continuous, strong ignition source (like a direct open flame) to catch fire. It is significantly harder to ignite than highly flammable gases like propane.
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.
Yes, R-22 (chlorodifluoromethane) is significantly heavier than air.
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+.
