This group of synthetic refrigerants is not subject to a ban on use. This means that installations using R134a,
The banning of R134a, along with 27 other refrigerants, in new domestic refrigerators and freezers from January 1, 2021, is expected to open the way for the use of hydrocarbon refrigerants.
A High-Performing Alternative to R-134a
Opteon™ XL10 (R-1234yf) refrigerant is a non-ozone depleting (ODP) hydrofluoroolefin (HFO) option that meets the industry's growing demands for sustainable, safe, and effective solutions.
134a is banned for new LD vehicles in the U.S. as of October 2024. 134a production is being reduced by EPA [Environment Protection Agency] mandate for all HFCs in the U.S. 1234yf could possibly be caught up in PFAS bans in Europe and U.S. unless exemptions are made.
By 2024, ban on R134a refrigerants in chillers is confirmed. United States. Some refrigerants, including R134a, R410A and R407C, will be banned for use in new chillers in the United States as of January 1, 2024.
HFC-134a will no longer be allowed in nonroad vehicles as of January 1, 2028. Servicing of existing vehicles using HFC-134a with HFC-134a will not be impacted and will continue to be allowed.
In the first half of 2024 we'll phase out our R-410A dedicated models and introduce -01 refrigerant versatile models, compatible with both R-410A and R-454B refrigerants.
R513A was developed as a replacement refrigerant for R134a. R513A is a modern, non-flammable refrigerant designed to replace R134a in a wide range of applications. It provides a sustainable solution for both new systems and retrofits.
Internal heat exchanger for R1234yf refrigerant (photo: NRF) As you can see from the above description, R134a and R1234yf refrigerants are not completely identical and their substitution will always result in faster degradation of the A/C system and eventually lead to costly repairs.
Still, the answer is an emphatic, “No.” Not only would a retrofit of this type negate the environmental benefits of R-1234yf, but it would also be a violation of Federal Law under Section 203 of the Clean Air Act: “tampering” with a vehicle's emissions control device.
In the United States, vehicles produced after 2021 no longer contain R-134A in the air conditioning system. In other parts of the world, including the United States, there are restrictions around using 1,1,1,2-tetrafluoroethane. Specifically, in California, retailers can deny selling customers canned R-134a.
According to its manufacturer, Chemours, use of R-1234yf has grown so much since the refrigerant replaced the long-established R-134a that it's now used in 95% of new cars sold in the U.S. An estimated 220 million cars on global roads are also using it.
The mixing of R-134a with R-1234yf will change refrigerant pressure and may result in evaporator freeze-up on pressure control systems, reducing system airflow.
R134a has been found to have a lot of greenhouse gas potential, as it can end up in the atmosphere and take forever to break down. For that reason, all new vehicles sold in America after the year 2021 can no longer use this type of refrigerant.
R-22 was a commonly used refrigerant that is being phased out because of its harmful impact on the ozone layer.
A. As of January 1, 2011, no person shall sell, supply, offer for sale or manufacture for sale in the State of California R-134a automotive refrigerant in a small container unless it has been certified for use and sale by CARB.
The GWP for R-134a refrigerant is 1,430, making it 1,430 times more harmful than carbon dioxide when released into the atmosphere. There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a, and R-744.
Most cars hold between 28 and 32 ounces of refrigerant (or about 2—3 12oz cans), however larger vehicles and those with rear A/C will likely hold more. Check your vehicle manual for the system capacity for your specific vehicle.
R1234YF is ridiculously expensive compared to R134A, like 10 times the price. (For reference - I can buy a 10 pound cylinder of R1234-YF on eBay for $500. A 30 lb cylinder of R134A is $150 - $200.) It is also takes more expensive equipment and a significantly longer amount of time to charge a R1234-YF system.
This group of synthetic refrigerants is not subject to a ban on use. This means that installations using R134a, R407C and R410A can simply be refilled after 2030. However, there will be significantly less synthetic refrigerant available in the future due to production limitations.
R-1234yf refrigerant. To date, most auto manufacturers are using the hydro fluoro olefin (HFO) refrigerant R-1234yf as the replacement of choice for R134a.
R32 and R152a have a reduced global warming potential than R134a, which indicates that R32 can be used as substitute for R134a in refrigeration systems.
For homeowners, the 2025 refrigerant changes mean new air conditioning systems purchased after this date will likely use R-32, R-454B, or other low-GWP refrigerants.
If your system is nearing the end of its life, replacing it before 2025 could be a smart move to avoid higher prices later. Rising Repair Costs: If your system requires frequent repairs or uses R-22 refrigerant, which is already phased out, you might be better off replacing it now.
Starting January 1, 2025, all new residential air conditioners and heat pumps must utilize A2L refrigerants. Older refrigerants like R-410, which are likely the refrigerant used by your current system, are being phased out. These new systems are designed to have a lower global warming potential (GWP).
