@@robertinoggprobably not I’m sure the density and weight of both are slightly different. If you’re a math guy I’m sure there’s a conversion formula to give you a good number.
How do you calculate the charge weight for 134a from the spec 1234yf weight printed on the sticker under the hood? Or do you just go by the low and high side pressures with AC running?
He is right, it works great, just have to remove all the old new stuff. All you are doing is violating a clean air act. LOL And as car guys you know how we all feel about that right??
Thanks mango dango! This was a good video! While R1234yf is better for the environment... it's hard to justify the outrageous price it costs. I'm tempted to vacuum out the refrigerant and convert to R134a like you have done.
134a systems are backwards compatible with 1234yf oil. But not the other way around. 1234yf is more reactive, and will break down 134a oil, so they made a special oil that resists the breakdown from 1234yf, therefore still being able to lubricate 134a systems.
The R134a pressure is a little higher than the 1234y so you have to be careful. If you make the pressure get too high with the R134a In the 1234y system it can black up the system and damage your compressor
Only time that the pressure is higher is when the ambient temperature reaches 150 degrees or higher. However the pressure difference is very slight. I had to get certified for the 1234yf. The two gases are very similar.
How many cars have you replace the Ac system from r1234yf to r134, how safe is it? I’d like to try to do so on a 2017 Ford Escape se. Any extra advice ? Thanks for the video.
The factories implicitly admit the two work together. My sisters 2015 Fiat 500 is tagged for 134a...but has a 1234 low pressure port. They flat told us to charge it with 134a...
Backward compatibility will always work without any issues, forward compatibility is not. "For example - you can add R134a to a R1234YF system, but you can not add R1234YF to R134a system. Just like USB ports, you can go to USB 2.0 to a 3.0+ but you can not go from a 3.0+ to a 2.0, anyone saying otherwise is a Mechanic or a Federal shill. Plus you can always go back if needed, like if you were going to sell, by just doing a full purge of the system and replace.
@@Matias-bw1eq Np, As stated in my first statement all systems are backward compatible. Use Ac--Pro.v101, with needed connectors R1234yf to R134a (Seal, Oil and Gas)(low & high), unless you have all the necessary items separately, Good Luck.
Just FYI, the psi recommend pressure for R134a is acceptable, very slight difference from the psi of R1234yf. Not even worth stating, Research and Knowledge is key.
So, what you're saying is you literally don't have to replace any components to do this? What about the oil? Do you have to replace the oil with pag 46?
POE oil in the newer systems works with either. There's literally a Mercedes 2013 recall TSB that specifies NOT to replace the oil. Mercedes recalled a bunch of SL in europe bc the new stuff was flammable in crash tests, pumped the old stuff out, replaced hose fittings, refilled with 134a, and put new stickers on it.
134A is less damaging to your AC components and costs much less. Eventually, when economies of scale catch up, the price of 1234YF will fall. However, other comments are correct: an individual who does this violates The Clean Air Act. Each violation is a $2,500 fine for individuals and $25,000 fine for companies. Will you be caught? Probably not. But the faster all vehicles and mobile AC units are converted to 1234YF, the faster the price will drop.
Not meaning to read like I'm making fun of the guy in the video, but I've never heard someone sound like they are talking underwater constantly. I feel bad for the guy.
I have a Dodge Charger 392 and where i live i can’t find r-1234yf they told me you won’t have a problem with r-134a and also about my warranty I’ve already voided my warranty i dont have a problem. Please tell me is it going to effect the ac compressor??
The guy giving wrong advice about Freon he has no knowledge about is using the worst Freon you could ever use known as ac pro. It’s full of all kinds of bullshit that you don’t want in your ac system
For someone claiming others don't know anything, you might look into how freon hasn't been used since like the 80's... Freon is R12, the generic term is refrigerant, other than R12 none of the refrigerants are freon
its illegal to retrofit a new system to use R134a, I would not suggest this at all. and another reason I would not suggest this is the oil properties (yes yours may use PAG but many use PAO which is not compatible with R134a.) etc are not the same and you're just asking for a failure. please do NOT listen to this video.

I use r134a on my yf recommended car and it works... it's still working fine as of now...been over 4 years now.
They also said R134 wouldn't mix with R12 but alot of people did it and it works just fine for many years
In fact a alternative refrigerant called freeze 12 is a mixture of r12 r134a r12 and hydrocarbons
Wrong, it was R142 which helped with oil suspension@@williamvaughan1218
Converted mine 20 years ago by slapping fittings on it and charging it. 20 years later it still works perfectly. Not one problem.
the issue is the 134 will leak / is too small compared to r12
Thanks for the video. With the cost of 1234 ,the EPA can suck it. I'll use what works
Ive seen 134 used in 1234 systems without any problems. Several different vehicles, all working just fine years later.

Did you have to change the oil out In you're compressor . Because they say 134 A takes a different oil. In the compressor.🤔

My wife hopes so
Nah…they’ll just require you to wear special underwear that filters the fart 😂
Do I still have to vacuum it out if my ax doesn’t work at all?
You should always vaccume for moisture
How about propane in a modern system. It woeks in a r12 i know for a fact
Do you vacuumed the oil to?

I used it in my dodge Durango it it works fine
