When was R-1234yf required on vehicles?
The refrigerant R-1234yf was required to be used in new vehicles starting in 2017 in the United States and the European Union. This new refrigerant was mandated to replace the previously used R-134a due to environmental concerns over the high global warming potential of R-134a.
The Transition to R-1234yf
R-134a had been the standard refrigerant used in vehicle air conditioning systems since the 1990s, replacing the earlier R-12 refrigerant. However, R-134a was found to have a high global warming potential, meaning it contributed significantly to climate change if released into the atmosphere. In response, regulatory bodies in major markets began mandating the use of a more environmentally-friendly alternative.
The refrigerant R-1234yf was developed as a replacement for R-134a. It has a much lower global warming potential, making it a more sustainable choice for vehicle air conditioning. The transition to R-1234yf was phased in over several years to allow automakers time to redesign their systems and ensure the new refrigerant could be safely used.
Regulatory Timeline
- United States: R-1234yf was required in new vehicles starting in the 2017 model year.
- European Union: R-1234yf was required in new vehicle types starting in 2013, and in all new vehicles starting in 2017.
- Japan: R-1234yf was required in new vehicles starting in 2013.
The transition to R-1234yf has been a significant undertaking for the automotive industry, requiring changes to vehicle design, manufacturing processes, and service procedures. However, the move to this more environmentally-friendly refrigerant is an important step in reducing the environmental impact of the transportation sector.
Is it illegal to put 134a in a 1234yf system?
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.
What year did cars stop using 134a?
2022
Recently, auto manufacturers have switched to a new type of freon that is even better for the environment. R134a freon was “totally banned” for auto manufacturers in the European Union in 2017. Meanwhile, US manufacturers were required to phase out R134a freon by the 2022 model year.
What is the life expectancy of R1234yf?
11 days
R1234yf has an atmospheric life of 11 days compared to a 13 year lifespan for R134a. R1234yf compares in efficiency to R134a and has the same cooling capacity. Vehicles using R1234yf are expected to use less fuel and produce 20-30% less CO2 which means a significantly reduced carbon footprint. R1234yf is safe to use.
What year did 1234yf become mandatory?
The First Air Conditioning Refrigerant Replacement Mandate Since The Early 90's. A new automotive refrigerant R1234yf is being used in many late model 2015 and newer vehicles. The United States EPA has mandated that all new vehicles use R1234yf by 2021.
Is 1234yf being phased out?
As of 2021 all Vehicles will have the new R-1234yf refrigerant in the vehicle. Advantage Automotive can Service Vehicles will R-134a and R-1234yf. There is no known replacement for the R-1234yf as of today.
Is R1234yf being discontinued?
R-1234yf is in the newer vehicles. As of 2021 all Vehicles will have the new R-1234yf refrigerant in the vehicle. Advantage Automotive can Service Vehicles will R-134a and R-1234yf. There is no known replacement for the R-1234yf as of today.
What year did cars go to 1234yf?
2013
General Motors began introducing vehicles to the market utilizing this new system in 2013 with full conversion in 2018. Chrysler, Honda, and Subaru models followed in 2017. It is anticipated that by 2025 all vehicles will contain 1234YF.
What is the life expectancy of R-1234yf?
11 days
R1234yf has an atmospheric life of 11 days compared to a 13 year lifespan for R134a. R1234yf compares in efficiency to R134a and has the same cooling capacity. Vehicles using R1234yf are expected to use less fuel and produce 20-30% less CO2 which means a significantly reduced carbon footprint. R1234yf is safe to use.
Can you mix R-1234yf with R-134a?
Refrigerant types are not to be mixed. The usage of dyes and sealants is discouraged.
Do all new cars use 1234yf refrigerant?
R-1234yf is used in almost every new car sold in the U.S., but the EU is discussing a ban and the industry is investigating alternatives like CO2 and propane.
