What's R1234yf? What's R134a? Automotive HVAC training 

The silent part

I am happy to use it if it does not cost me extra. The governments are all but bunch of Hypocrites. If your vehicle releases higher emission you have to pay more. But when they issue a 2 weeks work permit for a job that only require 2 days at max and cause unnecessary traffic jams and emission thats all right bcos whatever they do is right.

Yes, those are natural gases and can't be patented. unlike 1234yf which is synthetic and can be patented even though it's inferior to the ones you mentioned.

I can tell you it’s not efficient for my flag hours. That 1234yf machine we’ve got in the shop takes forever to do a recovery and a charge. Literally takes 3X as long to service a 1234yf system vs a 134a

Correct me if I'm wrong but automotive A/C systems are designed to cool the cab about 15 +/- degrees difference based on ambient temperatures. We will never have a 50° difference from ambient temp unless you go old school and use a propane system (good luck with that)

@@jaimeflores1575 couple years ago I had a 99' Grand Prix that I replaced the compressor on and it would consistently blow 38-40 degrees F at the vent no matter the ambient temperature. Not sure how or why but I've never had a/c system work as well in a vehicle as that car did.

@@PachínGalh No it wasn't. But I realized he said "cab temperature". It's not uncommon for a/c to blow around 40 F right at the vent. The cab temperature itself will never actually get that cold. So he's probably right about what he said.

I had a few 1234yf cars and always thought they didn't cool that well. Always blowing on high. I do live in Florida but thought something wasn't right. I just purchased an 11 year old truck with 134a and the cab is turned into an ice box after a few miles of driving. It's clear to me that 1234yf is dumb. More expensive parts and blows warmer. I have owned four 4th generation Rams with the new junk and one with the old stuff. R134a is king!

I am also interested in that

What about the reply to your comment please

I am also interested

Normally it's the tanks test date - in the US they need retesting every 5 years I think

Yes.you’re right

I think it’s ex factory date

Bruh, I recently bought myself a 2015 Fiat 500 Abarth and it has this new R1234YF and it is so bad. You are right, the lowest temperature it is able to achieve is nothing close to previous R134a systems. Best way to describe it is, R1234RF feels like R134a but with a system that is low on refrigerant. Personally, since 2012, I've used another refrigerant R152a on every single one of my vehicles. Gets colder, gets colder faster, and half the molar mass as R152a and past 1500 rpms it feels like the AC isn't even on. It gets colder than R12. R152a is exact same chemical as R134a, but about 64% of the molar mass, so all you do is evacuate R134a, vacuum, and put in the R152a. BTW, R152a is literally Compressed Air (Canned Duster) you find at the computer section at Walmart. There is no vehicle that will need more than 20oz of R152a, which is 2 cans. 2 Cans of compressed air will cost you about $8 at Walmart. Best Refrigerant ever. I planned to put R152a into my car maybe this weekend if it doesn't rain, but I definitely need to get rid of this R1234RF, it's complete garbage. Here in Texas, when it gets to 100'F it feels like I dont even have the AC on. It's kinda embarrassing to have a passenger with me and feel that. You should try R152a, it's easily far and away much colder than any refrigerant I've ever experienced, easily.

@@ImJustKindaHere I done propane on a customer that was stubborn about using it and I was surprised how good propane is I know it's extremely dangerous buy God damn on a 105 degree day it was getting down to 22 degrees, but I'll stick to my r12 and r134a they're good enough for my car the jeep my wife has I already dumped that stuff out and put r134a so that issue was resolved

@@alextepozteco3681 Trust me, try R152a (Air Duster) over R134a, it will blow you away by how little parasitic drag it puts on your engine (about half of R134) and how substantially colder it gets and how it gets colder faster. Again, only put in 64% of the ounces that it normally requires R134a. So if it normally asked for 12oz, put in only 7.7 oz R152a gets so cold that you will be forced to raise the temp on your AC system (which also removes more parasitic drag on your engine). Only real tool you need to get R152a (Duster can) into it is a "side can tap" to be able to puncture into the side of the can to syphon the liquid. Again, gets colder than R12, runs at a far lower pressure (so if you leak out R134, this could be a fix for it), half the drag on the engine, and gets colder faster. Runs at lower pressure than R12 too. Try it my dude, you won't regret it :D

@@ImJustKindaHere 100% correct....preach it brother !...it must use the Pag oil..........if you clean out an old R12 unit and put in 152a...just flush out the old mineral oil and use the Pag oil and 52% charge weight for the new refrigerant

Scotty Kilmer did a good video about this and it's a good one

Glad to hear it

Can't you just pump r134a in the system and be done with it? Or does anything else needs changing?

@@MrRightNow There is more to it dude, you need to make sure you don't have a leak first. Also the R1234yf needs to be properly recovered. You will need a manifold gauge set, a vacuum pump & R1234yf Quick-connectors. NEVER ...EVER...mix the gasses/refrigerants. Some basic knowledge is needed. You can learn that easily on youtube videos, PLENTY good one's out there. Its really not that difficult at all. All it takes is the willingness to learn a bit.

@@0815funkmaster this is Innocence if pumped out and now fitting applied there is no real problem BUT do not mix the two GASSES

ya you can convert 1234yf to r134a but not the other way around

@@okornel Fair enough 👍

I feel sorry for your equipment

I never trust anyone who calls the hood a bonnet.

@@KrisMinnear 😂 Neither would I if I were on your side of the pond!

That’s the proper way to close it on the Tesla. It typically won’t lock fully when dropped.

Do you interested in the cheaper ones?

Very clever 😂😂😂

Dont you mean a pos that won't ever get to 200k miles

@@CmurkGam3ing There's Tesla's with over a million miles on them.

@@mattwolf7698 not on original batterys in a 10 year time frame

R290

@@HDXFH you are correct.

You just pump it in instead of r134a? No modifications?

No mods just don't crash and spark off and explode. That's all.

It’s extremely low flammability, in comparison to r290 (propane). But it’s still junk. I’ll be converting the new car to r134.

If your vehicle uses gas then you’ve always had a “bomb on your car”

@@SeanBoss I wish I could give this a million likes.

I suspect you need more experience with the English language, you’ll get better.
