No, you cannot replace R22 with R32 in an existing air conditioning unit. They cannot be mixed or directly swapped.
There is no direct "drop-in" replacement for R-32 refrigerant. R-32 operates at different pressures and discharge temperatures than older refrigerants, requiring specially designed compressors and lubricants. If you are looking to replace the refrigerant in your system, here are the specific approaches based on your setup.
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.
No, R32 is not compatible with R22. You cannot mix them, nor can you use R32 as a "drop-in" replacement for an existing R22 system.
For R32 model, use pipes, flare nut and tools which is specified for R32 refrigerant. Using of existing (R22) piping, flare nut and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly result in explosion and injury. Thickness of copper pipes used R32 must be more than 0.8mm.
R32 cools significantly better and more efficiently than R22. Because of its superior thermodynamic properties, R32 transfers heat much faster, requires about 60% less refrigerant to achieve the same cooling capacity, and can reduce electricity consumption by roughly 10% compared to older R22 systems.
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.
Potential Drawbacks of R32
Despite the growing popularity of R32 refrigerants, there are some potential drawbacks associated with its use. These include flammability and safety concerns and retrofitting and compatibility issues.
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.
As of January 1, 2020, the United States banned the use of the R22 refrigerant, commonly known as Freon.
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+.
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 $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.
No, you generally cannot legally buy R-32 refrigerant in the US without a license. The EPA restricts the sale of almost all regulated refrigerants and their substitutes.

No, R-32 is not propane.
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.
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.
