The primary refrigerant currently being phased out is R-410A (an HFC). Driven by the EPA's American Innovation and Manufacturing (AIM) Act, the production and importation of new HVAC systems using R-410A are banned. The industry is transitioning to low-GWP (Global Warming Potential) alternatives like R-454B and R-32.
Yes, eligible R-410A equipment can still be legally installed.
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.
In 1987 an agreement called the Montreal Protocol was signed to begin the worldwide phase out of ozone-depleting CFCs and in 1992 HCFCs were added. In 2010, manufacturers were no longer able to produce new equipment designed with R22 and at the end of 2020, production and import of R22 will be eliminated.
There is no direct "drop-in" replacement for R-410A in existing systems. Because R-410A operates at extremely high pressures, using unapproved alternatives is dangerous. For new equipment, the industry is transitioning to R-32 and R-454B. For existing systems, continue using virgin or reclaimed R-410A, or use a certified retrofit blend like R-470A.
Energy Savings: R-32 refrigerant has about one-third the global warming potential (GWP) of R-410A, and it also offers energy efficiency. It is efficient at transferring heat.
No. The pressures, fittings, and lubricants are completely different. R-134A would leave the system severely undercharged and the wrong oil chemistry would likely damage the compressor. Home AC systems are built for R-410A specifically and the service ports are sized to refuse R-134A fittings.
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.
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.
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.

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 primary replacements for R-410A in new HVAC systems are R-32 and R-454B. Both are environmentally friendly "A2L" (mildly flammable) refrigerants. Because of this classification, R-410A cannot be directly substituted with these new gases; entirely new equipment designed for safety and handling is required.
The "20-degree rule" is an HVAC standard stating that an air conditioner can generally only cool a home by about 20∘F20 raised to the composed with power F20∘F compared to the outside air. If it's 95∘F95 raised to the composed with power F95∘F outside, the lowest your AC can typically maintain inside is around 75∘F75 raised to the composed with power F75∘F. Setting the thermostat lower wastes energy without cooling the space.
No, you cannot replace R-410A with R-454B in an existing HVAC system. They are not interchangeable. Attempting to use R-454B in equipment designed for R-410A creates major safety and reliability problems.
Many Amish homes are built with plenty of windows to help circulate the air and bring in the cooler overnight temperatures. They open the windows on the top floors to help the heat escape while the family retreats to the lower grounds within their homes for comfort.
By 2036, the EPA aims to reduce the use of HFCs by 85% compared to 2011-2013 levels. This final phase will ensure that R-410A is almost entirely eliminated from the market, pushing businesses to fully transition to sustainable refrigerant options.
Yes, 2027 is widely expected by climate scientists to be hotter than 2026, with a high probability of breaking global temperature records.
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.
The most expensive refrigerants are heavily regulated, ozone-depleting substances that have been phased out, alongside newly developed, complex hydrofluoroolefin (HFO) blends.
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.
R32 is much better for the environment: R32 has a global warming potential of 675, which is about 68 percent lower than R410A.
Any Carrier HVAC systems installed moving forward will use Puron Advance refrigerant instead of R-410A.
