No, you cannot simply pour R-410A into an existing R-22 system.
Converting an older R-22 air conditioning system to R-410A typically costs $4,350 to $9,300+ for a standard residential setup, including parts and labor. Because R-22 operates at a much lower pressure than R-410A, you cannot simply swap the refrigerants.
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.
No, you cannot directly replace R-22 with R-410A. They are chemically distinct and cannot be mixed.
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.
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.
It is possible to use a different type of refrigerant inside an R-22 system. There are “drop-in” refrigerants that serve exactly this purpose. When someone has an R-22 leak, it's possible to remove all the R-22 from the system and replace it with a drop-in refrigerant.
Are you required to have a license or to be certified to handle and purchase R-410A? You are required to have an EPA Section 608 Type II or Universal certification license to handle R-410A, but no license is legally necessary for purchase.
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.
R-410A is currently being phased down rather than fully banned, with the production of new R-410A equipment already banned. The remaining supply will be gradually reduced by 85% through 2036.
You can no longer buy newly manufactured R-410A HVAC units. The production of new R-410A equipment was legally prohibited in the United States starting January 1, 2025. Today, manufacturers exclusively produce units that use low-Global Warming Potential (GWP) alternative refrigerants like R-32 or R-454B.
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.
R-410A was invented in 1991 and hit the commercial market in 1996, when Carrier Corporation first introduced residential air conditioning units using it.
Yes, eligible R-410A equipment can still be legally installed.
Converting an R-22 system to R-410A is not a simple refrigerant swap. Because R-410A operates at significantly higher pressures and uses different synthetic oils (POE) compared to R-22's mineral oil, you must replace the compressor, condenser, and evaporator, or install an entirely new, matched HVAC system.
Expect to pay between $𝟓𝟎 and $𝟏𝟎𝟎 per pound to have R-410A refrigerant recharged by a licensed HVAC technician. The exact cost depends on your location and the service provider, as the price covers the refrigerant, leak checks, technician labor, and equipment overhead.
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.
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.
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.

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.
No, you cannot legally purchase R-410A with a Section 609 certification.
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.
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, you can install a 410A-rated evaporator coil on a R22 system, as modern aluminum coils are designed to handle the higher pressures of 410A and are compatible with R22 refrigerant. However, the metering device (piston or TXV) inside the coil must be matched to the R22 system requirements.
