R134a is being phased out because of its exceptionally high Global Warming Potential (GWP). It traps heat in the atmosphere at 1,430 times the rate of carbon dioxide, making it a potent greenhouse gas that significantly accelerates climate change.
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.
It is the most abundant HFC in the atmosphere. The restriction of HFC-134a will occur under a broader prohibition of any substances with a Global Warming Potential (GWP) higher than 150 in the MVAC sector. HFC-134a will no longer be allowed in nonroad vehicles as of January 1, 2028.
If you're looking for a low global warming potential (GWP) alternative alternative, consider Opteon™ XP10 (R-513A)—a new generation hydrofluoroolefin (HFO) refrigerant replacement for R-134a in stationary equipment.
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-454B. R-454B is a next-generation refrigerant designed to replace R-410A in HVAC systems. R-454B is a hydrofluoroolefin (HFO) blend refrigerant, composed of a mixture of R-32 (difluoromethane) and R-1234yf (2,3,3,3-tetrafluoropropene).

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.
Though it is still illegal to vent the refrigerant into the atmosphere, it is not prohibited to charge a leaking system or to sell 1 pound cans. If you Google “charging ac system with a 1 pound can”, there are 12,700,000 results. R1234yf is not without some problems.
R1234yf is the next-generation refrigerant replacing R134a in new automotive models. It boasts an ultra-low GWP of less than 1, making it compliant with strict environmental regulations globally, including the EU's MAC directive and U.S. EPA rules. As of 2021, most new cars sold in the U.S. use R1234yf as standard.
R-410A Is Not Illegal To Own In 2026
You can repair it. You can have it serviced. Nothing in the federal rules is written as “homeowners must replace existing R-410A equipment by a certain date.” The EPA has been clear that consumers can continue using current equipment until the end of its useful life.
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.
Don't run a system without/low on refrigerant. At best it won't work correctly, at worst you will end up paying to replace your system.
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.
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.
R-22 refrigerant prices range from $90 to $250 per pound. Since you'll need between 6 and 12 pounds to refill a home AC, costs can reach between $660 and $2,400 for a refill of R-22 refrigerant.
While R-1234yf could be the perfect replacement for R-134a, there is one major challenge with this new technology. The R-1234yf is much more reactive than R-134a. On the positive side, this higher reactivity is why R-1234yf is so much more friendly to the environment.
While the production of new R12 is banned, it is not illegal to sell or use R12. In fact, many of the cylinders and cans of Freon R12 sold for decades throughout the United States are still around today.
Easy to Use and Works Great for My AC
This refrigerant did exactly what I needed it to do. It was easy to attach and filled my A/C system quickly without any leaks or issues. My car's air is blowing cold again, and it only took one can. The pressure gauge I used showed perfect levels afterward.
Civil Penalties: The EPA can impose civil fines up to $44,539 per day for each violation. This means that even a single venting incident can result in tens of thousands of dollars in fines. Criminal Penalties: In cases of willful or repeated violations, criminal charges may apply.
One of the primary reasons for the switch from R-134a to 1234YF refrigerant is environmental impact. Traditional refrigerants like R-134a contribute significantly to global warming. While R-134a doesn't harm the ozone layer like older refrigerants (such as R-12), it still has a high Global Warming Potential (GWP).
This translates into the so-called “Refrigeration Cycle”. In this, the refrigerants are transformed to be able to extract heat from the environment and produce cold. This cycle comprises four stages: compression, condensation, expansion, and evaporation.
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.
El Nino set to heat up 2026 to the earth's hottest year on record in the coming months, with 2027 on track to be even warmer. Climate scientists are now largely convinced the world is warming faster than at any time in human history.
What is R-454B? R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in current HVAC manufacturing. R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO).
