Technically, you can convert an R-22 system to R-410A, but it is rarely recommended and often not cost-effective. Because R-410A operates at significantly higher pressures (nearly double) and requires different lubricants, a "conversion" is actually a near-total rebuild of the equipment.
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.
Yes, eligible R-410A equipment can still be legally installed.
No, you cannot directly replace R-22 with R-410A. They are chemically distinct and cannot be mixed.
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.
Yes, you can still buy R-410A equipment. While the production and import of new R-410A systems were banned at the manufacturer level starting January 1, 2025, retailers and contractors are still legally permitted to sell and install existing overstock manufactured before the cutoff date.
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.
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.
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.
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.
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.
Yes, you can still install legally compliant R-410A systems, but with strict conditions.
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.
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.
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.
The price of R-410A is surging due to the EPA's phasedown under the American Innovation and Manufacturing (AIM) Act. Federal mandates are strictly reducing the production and import of Hydrofluorocarbons (HFCs) like R-410A. With supply intentionally restricted and demand remaining steady, distributors and contractors are driving up prices.
No, you cannot directly replace R-22 with R-410A. They are chemically distinct and cannot be mixed.
A 1.5-ton AC typically requires 1.2–1.5 kg of refrigerant, depending on the model and type (split/window).
If you need refrigerant for your air conditioner, you'll need to contact a professional heating and cooling technician. Under EPA regulations, only a certified professional can recharge your home's HVAC system. You should never try to recharge the A/C yourself, even if you have a home air conditioner recharging kit.
Yes, you can still buy R-410A equipment. While the production and import of new R-410A systems were banned at the manufacturer level starting January 1, 2025, retailers and contractors are still legally permitted to sell and install existing overstock manufactured before the cutoff date.
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+.
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.
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.
