As of 2021, ALL vehicles sold in the US are now equipped with 1234YF Freon in the Air Conditioning System. If you have a vehicle that needs Air Conditioning repairs, we at Automotive Blessings have the machine and training to accurately repair the system.
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.
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.
It is anticipated that by 2025 all vehicles will contain 1234YF. Don't fret, however, if your current vehicle requires 134a. Though 134a is not compatible with 1234YF and is expected to be phased out, it is still in production and will continue as long as there is a demand for repair of older vehicles.
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.
The Intergovernmental Panel on Climate Change has since added R-134A to its list of greenhouse gases, declaring definitively that this refrigerant is a poor choice for the future of the planet and its inhabitants.
Switching to R1234yf refrigerant is a step towards a greener future, but it comes with higher costs due to advanced equipment, stringent regulations, and specialized training.
If you are purchasing less than 2 pounds of either R-134a or R-1234yf, you are not required to have a license to purchase either refrigerant. However, if you are working with 10- and 25-pound single-use recyclable cylinders you will need Section 608 Technician Certification.
“More than a trend, R-1234yf is here to stay and is widely accepted as the 'future of automotive refrigerants — in use now.
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 systems that control freeze protection by pressure may encounter loss of cooling performance if charged with 100% R-134a. This is due to the requirement of R-134a to have a lower setting of 3.3 psig to achieve freeze protection at 32 F. This may result in a 4-degree F.
In 2010, Chevy, Buick, GMC, and Cadillac announced that their 2013 vehicles would use this new refrigerant within the U.S. Since then, many other automotive manufacturers have transitioned to using R-1234yf with the EPA scheduling all newly manufactured vehicles to be equipped by 2021 (click here to read more).
When undertaking lubricant selection for HFO 1234yf oil compatibility systems there remains a market acceptance that specialty synthetic 'double end-capped' polyalkylene glycols ('PAGs') are the preferred OEM choice.
The EU is currently revisiting R-1234yf emissions rules and may ban the substance in a few years. In the U.S., the EPA stands by its use.
“ R-1234yf is an even more environmentally-friendly gas than R-134a and has been making its way into some cars since 2013. MOTOR Selectline.
Adapters to convert an R-134a manifold gauge set to be able to connect to an R-1234yf system are readily available, so along with eventual availability of a recovery-only machine, the opportunity to convert an R-134a system to R-1234yf exists.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.
The R1234yf refrigerant that will be required in all new cars next year has actually been found in vehicles since 2014 when Chrysler began using it in the Dodge Demon and Jeep Trackhawk, among others.
Indeed, according to Koura, R444A lowers the cabin temperature by around 2°C less than R1234yf, and reaches a temperature of 22°C four minutes faster. Furthermore, the manufacturer claims that this refrigerant is more economical.
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.
Switching to R1234yf refrigerant is a step towards a greener future, but it comes with higher costs due to advanced equipment, stringent regulations, and specialized training.
Avoid breathing gas. Provide adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Put on appropriate personal protective equipment.
