Don’t Buy Cars that Use this New Type of Refrigerant in the AC System

Don’t Buy Cars that Use this New Type of Refrigerant in the AC System

Rev up your engines!
today I’m going to talk about the new bad change that’s occurring in modern car air
conditioning system, by law in the United States, the are changing
the refrigerant from r134a to r1234yf a new type of refrigerant,
now years ago the change was made from r12 which was called freon, to r134a
and that was a big enough pain, now it’s all based on laws to not deplete
the ozone layer, the 134a is less ozone depleting than the
r12, and this new one is much less ozone depleting,
but if you ask me, the tiny amount of refrigerant that’s in cars that sometimes leaks out it’s
that big of a deal really, when you consider how much gasoline we burn
and pollute the atmosphere with that stuff, this whole changing refrigerant scene that
they’ve been doing lately, hey it’s kind of like closing the barn door after the horses
have already ran away, now the first thing with this new refrigerant
is the cost, here’s a 134a canister,
it’s 30 pounds and it costs me about $95 last year,
and here’s a 10 pound container of the new R1234yf it costs $1,000 for 10 pounds so that
would be $3,000 for 30 pounds, so right away you can see, they’re ripping
everybody off, they’re charging $3,000 for something that
I use to pay $90 for and there’s no way it costs that kind of money to make this stuff,
it’s just total nonsense, and not only are you paying a lot more for
the refrigerant, as a mechanic I have to go out and buy a new
recycling machine, because by law I have to use a recycling machine for each type of refrigerant,
now I already have one for the 134a, but to work on the new r1234yf system, I got
to buy another machine, so as you can already guess, having these
new AC systems worked on if going to cost you a whole lot more money,
but perhaps the worst aspect of this new r1234yf refrigerant is this,
the old 134a it’s virtually inflammable, it’s not going to start on fire, if you get in
a wreck and it leaks out or if it has a leak in the dash and gets inside and you’re smoking
a cigarette, it’s pretty much nonflammable under any condition you’re going to meet in
a car, but this new r1234yf refrigerant is actually
flammable, now you would think the scientists with all
their intelligence could come up with a better system than replacing a nonflammable gas with
a flammable gas in cars that people drive, let’s say you get in a wreck, the ac system
starts gassing out, that could start on fire, or if it starts leaking inside the evaporator,
that could start a fire inside your car, especially if you’re a smoker,
this flammability is such a big deal to some manufacturers,
listen to this, German manufacturers Daimler, Volkswagen and
others don’t want to use r1234yf in their vehicles but will do so for the near future
to meet U.S. refrigerant regulatory actions, they tested then in cars and said when the
compressor ruptured it could start fires inside the engine and they found something even worse,
that burning r1234yf emits toxic hydrogen fluoride gas,
you really don’t want to be breathing that stuff in if something happens,
instead the Germans are working on something called r744 which is CO2, carbon dioxide,
now of course we breath out carbon dioxide so it’s not flammable, it’s a very cheap gas,
but in itself it has a big problem, r134a and the new r1234yf, they have the highest
operating pressure at a high point of 300-400 PSI,
but the carbon dioxide system, it can operate at 1,400 PSI so there’s a lot
more pressure, and guess what, the higher the pressure, you have to build them stronger,
they have to be made better, they cost a lot more to make,
and with that extra pressure, of course they’re going to break faster,
and of course that much pressure in itself can be dangerous,
if you’ve got 1,400 PSI pressure in your dash and it blows up, it could send shrapnel all
over the place, so of course now they’re working on even more
complex systems where the CO2 system is all under the hood of the car, and then there’s
another cooling system that takes the cool air from that system under the hood and moves
it inside the dash, I mean these things are getting more and more
insanely complex for a system that worked fine in the first place,
but as it stands now, here’s a list of cars that presently use it, from BMW, Cadillac,
Chrysler, all the way down to Toyota, but as I see it hey, why are they switching
from a gas that works perfectly fine, is nonflammable, and switching it to a flammable gasm
to me it just does not make sense, so they really need to charge $3,000 for a
can of something that use to me $90, holding people hostage that want to be cool
in their cars, that’s just not right, but of course it gives you even more reasons
to hang on to your old car, that’s a 94 Celica, it came with r134a, it
still blows really cold, it’s got the original compressor on it,
but at least now you know what going on with this new refrigerant and you can make an intelligent
choice, maybe even complain to some of your legislature
about it and they might end up giving up with this stuff,
so if you never want to miss another one of my new car repair videos, remember to ring
that bell!

  3. This whole refrigerant thing is totally out of control. Years ago Freon was used as a propellant for hair spray, shaving cream and a whole lot of other things besides cooling systems. Today the EPA and other agencies are going nuts. The older home AC units using R22 are becoming out of date even though they work perfectly since R22 is now being sold for over 100 a pound. I also believe that Dupoint has a lot to do with all of this. They have the big money to control these things so that they can make more money at everyone else's expense.

  4. R134a takes 12 years to break down in the atmosphere and r1234yf takes 3-4. Besides most people are scared of this new refrigerant because they feel they will no longer be able to work on their own cars. With A/C that wouldn't be a bad thing considering a vast majority of people don't know what their doing. A lot of DIYers release refrigerant into the air because they don't have the means to recover it.

  5. Hey Scotty. I have a 1986 Nissan 300zx and I want to retro fit to use R134. Where can I go to get the system evacuated to get the old R12 and oil out? And how much is it going to cost. Thanks in advance.

  6. Recover the refrigerant and put R/134A in it. If you have a fixed position piston metering device you are fine. If you have an expansion valve replace it with an R/134A expansion valve and then replace the filter drier. When new refrigerants come out they will have a high price tag until it is mass produced. That is how companies pay for research and development. It also you executives pay for yachts too.

  7. That new stuff is flammable ( great ) it will be like the 80s car chase movies when the car hits the wall and ( BOOM ) 🔥

  8. Recently we had a bad car wreck (I mean – in our country). Five people dead, several cars completely burned. Guess what – they all had 1234yf AC (at least that's what AC people are telling).

  9. what about the contribution towards global warming due to R134a? 1400 plus GWP this is the main concern.

  10. R134A has no chlorine in it so it is not ozone depleting. The gov doesn't like R134A because of its supposed global warming potential.

  11. You can't use propane because it's flammable yet it cools better than all the other gases and cost pennies but the new gas is also flammable and cost 100 per lb?

  12. Got 1 even better than yours Scotty.
    R22 was changed to R410A bc of the so called "EPA Ozone damaging gases" Now they(scientists) realized that R410A is actually MUCH worse then R22 ever was.
    Now All HVAC manufacturers are scrambling to find and settle/agree on another Brand new Refrigerant that actually is better than the original R22.
    Then to top all this mess up. All the customers that paid huge money to change over from R22 to R4120a now have to pay again to change it up again. (plans in the works current by Gov't/ manufactures to make changes or switch/conversion by 2025)

  13. that be bad if they use this gas in household and commercial refrigeration with hermetic compressors if the motor windings arc out in the compressor can blow the whole works.

  14. It the auto manufacturer and epa are hand in hand wanting you to go to the dealership to get a/c work done that's all it is the epa gets funding from the government and auto manufacturer several million dollars and the manufacturer gets money back from the dealership it a win-win for them but not for you but they don't care

  15. Ford replaced AC on 2005 Lincoln . Year it's dying …free replacement of entire system twice. They forgot the fan. It was $200. So that and $800 original makes it a $1000 AC thanks Ford.

  16. R1234yf and Tesla……perfect together.

    Thx for the heads up Scotty.
    The corplutocracy just can't stop fůkin the people.


  17. Scotty, thank you SO much for that info. I used to be an ASE Certified master tech in a prior life for over 15 years. I remember the royal pain when 134a came out in the mid 90’s. Jump to present day, have been out of it professionally for 21 years but still do my own work. Anyway, my wife purchased a new 19 Murano and my son bought a 19 Jetta. Just checked them. To my surprise, the Murano is still 134a, however the Jetta is that new 1234yf. If it wasn’t for the great content you put here I never would have realized. Happy for what you do for the people but beyond ticked off about the new stuff. Love you and keep up the great work. Greetings from Pearland.

  18. I'm not going to say what political party thats doing it. ? but it's called government regulation all these nature goody two shoe people out there that want to save our planet that's going to die in 12 years

  19. Fluorine is the f in all refrigerants but seeing that Fluorine is in bigger concentrations here make me suspect maybe they are trying to find more uses for it.

    why not Fluoridate the toothpaste and water with more Fluorine why not lace our food supply and say it is to harden our teeth.

    why not make a tall claim that it is a great replacement for chlorine in swimming pools and make it an additive for swimming pools

  20. R12 was pennies a can (pint) in the 80's. R134a cranked up the price and didn't work as well. This is the obvious next step. They don't give a flip about climate change, but this R134a thing MUST BE STOPPED. LOL. Wouldn't it be nice if your representatives in Washington represented you instead of lobbyists?

  21. Cars are becoming more complex. With the locking of car computers to expensive ac systems. It going to hurt the computers. What about adaptive technology? You have not talked about that!

  22. R 12 etc was a fantastic refrigerant. It never hurt the ozone anyway. If it did, then why was the ozone OK for the fifty plus years they used and vented r 12 refrigerant? Only when the enviro-wackos at the epa "dictated" it did. The epa people are the "eco-commies". It's only going to get worse, get used to being screwed over, and being hot (no ac). True craziness here…

  23. R-12 was a "dream chemical", incredibly efficient, energy efficient, non-toxic, non-corrosive, stable. It was so good and so easy on the equipment, that there are fridges and ac units from the 1970s still running perfect, ice cold, running on r-12…

  24. Well who knew, the minute the DuPont patent expires, the refrigerant is suddenly bad for the environment and their stockholders.

  25. Talking to an air conditioning mechanic, he says the same thing. New gas system servicing/repair prices going upwards big time. Vehicles are becoming ridiculously high tech. No one will be able to work on, only the dealer's. They'll charge any price they like. Cheers from 🇦🇺

  26. Same thing happen to our 2017 brand new civic lx, less than 15k miles. Ran out of refrigerant because of his new bs ac. After doing some research now I know why.. This is ridiculously frustrating.

  27. Scotty, I like your site. Everything you say, makes good sense to me. You are very informative. I hope you didn't mind my joke about the 460 air.😊

  28. You can't , as the manufacturer is bound by EPA regs. Try and buy a new one with R12 and let me know how that goes for you?

  29. come on scott. ur an amazing guy but the tech is true and i just purchased 320d. its not nonsense. its more efficient and the reason to use the new ref is hybrid vehicles.

  30. alot of the refrigerant changes are due to the EPA. The EPA decides that some refrigerant or manufactureing of some refrigerants are less destructive to the ozone layer than other R134A is actually a HFC class refrigerant and should have no damage property's to the ozone layer. But who knows maybe because of the oil that R134A uses

  31. We pollute less than any other country. But in China, they pollute as much as they want. Their pollution eventually reaches us. So it doesn't make sense if everybody is not on the same page of not polluting.

  32. Scotty,
    FYI… inflammable means the exact same thing as flammable. If you were trying to say that r134 refrigerant us not flammable then you should have used one of the following words… Incombustible, fireproof, nonflammable.

  33. The phase out of the HFC refrigerants like R134A and R404A has been put on hold by the courts. Mainly because of the replacement hydrocarbon refrigerants, and the high probability of an explosion in the event of an evaporator or other leak from the system.

    Most refrigeration manufacturers are already making the move to hydrocarbon refrigerants. They have sealed motors and thermostats, but these things are still in kitchens with open flames on the burners of stoves, grills, and deep friers. You see the problem right.

    The reason that HFCs, which are heavier than air, were to be phased out is not because of the ozone depletion. HFCs are not ozone depletion gases, but have been deemed greenhouse gases by the powers that be.

    Since the only viable option at this time is hydrocarbon refrigerants, that explode, the courts have put a hold on the phase out of HFCs, for the time being.

    As a refrigeration technician, I only want to know how to handle the refrigerants. The good news is so far the government isn't requiring recovery of hydrocarbon refrigerants. They can be vented to the atmosphere unlike CFCs, HCFCs, and HFCs. Though that may change when enough technicians start fires in kitchens venting hydrofluorocarbon refrigerants. Time will tell.

  34. who in Washington dc is taking bribes so they all can get richer. It proves they don't care about peoples safty.or lives.

  35. It’s to stop climate change. To help future generations to live on our planet. Nothing to do with taxes. Old refrigerant prices will increase as they become less available.

  36. I think it's all bull! Cats, emission crap, computers in cars I wouldn't care if they went back to R12! Like the song goes both ends of the ozone burnin' funny how the world keeps turning! So in other words all this stuff everyone is complaining about is all crap!

  37. "They" did NOT outlaw Freon because it damaged the ozone layer. Freon is HEAVIER than air, so it goes down, NOT up. Freon was "outlawed" because DuPont's patent ran out and other companies started manufacturing it. DuPont created R-134a, patented it, and got their lackeys in Congress to outlaw Freon. This type of action is common with a fascist government and antithetical to a "capitalist" free market economy. LIVE FREE OR DIE !!!

  38. I would really hate being your neighbor! Hearing you yell/talk about nonsense. I hope your mechanic is not like Scotty Kilmer. And that annoying voice. God

  39. Well I am in air conditioning technician for residential and Light commercial and when I started HVAC 20 years ago R22 cost me $39 a jug for 30 lb now depending on where you buy it and what time of year you buy it it's between $400 and $1,200 and the replacement obviously was r410a net averages year-round about $200 for 25 lb so it's the same thing is the automotive it's not that we need a new system is not that the old system was flawed is that everything nowadays is a money grab and everybody's allowed to grab my money until I don't have any more to grab. And of course when I don't have any more to grab then they're going to start saying that I owe them. And when the limit has been reached on what I can have for debt to them then what it's illegal to have debtors prisons at least here in the US but I guarantee you that won't matter cuz they lock people up everyday for debts anyway

  40. I don't know what the refrigerant in my sister's 2017 or 2018 Nissan Murano AC uses, but it doesn't cool for crap in traffic. In Texas that's insane! It's hot as hell here.

  41. I was told it wasnt going to be put in vehicles till 2020 or 2021. I was unlucky to find out that my 2015 dodge dart haves this ac refrigerant type. Im living in the future. And i dont like it. I live in florida, where it gets as hot as 115 degrees. Sometimes the ac doesnt get cold enough to keep me from sweating. I should've studied it more.

  42. If you can't buy a car with 1234yf I'm guessing you're not going to be able to buy a car. Can you even find new cars in the lower 48 that don't have AC? And there are so many dangerous materials on you car already. I really doubt this is adding any significant extra risk. And actually the problem with 134 isn't ozone, it's that it's a global warming gas. It's like hundreds of times worse than CO2.

  43. R12 destroyes the ozone leaps and bounds over any thing a car or industry pollutes. Look at how the chemical bonds work. R34a works, but R1234 works better, and is 1000 times less polluting. The idea is to REDUCE emissions, not totally prevent them. Stop being a raging boomer over the costs of keeping out ozone intact. Just because something is labeled as "flammable" doesn't mean it will randomly burt into flame. We all know the facts that only the fumes of gasoline products are "flammable", yet we depend on them daily. Takes a very specific set of variables to ignite.

  44. Honey I smell something funny from the air vents. Oh that's your imagination I don't smell nothing, throw me another cigarettes will ya?

  45. One full discharge of r134a gives as much global warming as driving for a year, AND it depletes the ozone layer as well. Scotty you must do more research before you emit nonsense on the internet.

  46. I heard a long time ago that you could fill up an air conditioning system with propane and it would work and blow cold. It looks like we need to go back to that.

  47. CO2 canisters for paintball guns operate between 700-800 PSI and the CO2 is liquid at that point and extremely cold under pressure. With it being safe to breath and totally non-flammable, it seems like the research to utilize it in cars would be a no-brainer.

  48. You should do some research. You can buy Duracool (R290) as a drop in replacement for most applications. You are driving around with a tank of gasoline that is much more explosive than the tiny amount of refrigerant that is in a car. You are totally uninformed. Did you get paid well from the refrigerant companies?

  49. It's all about the greedy people In this world. I hate those people… I'ma stay with older cars I guess lol. Not too old though.

  50. Be careful people. Chemical companies make billions supporting global warming (climate change) theory. Follow the money.

  51. HFO-1234yf. The yf stands for you’re f€#£ed. Fire Protection Engineer here that has worked with these chemicals and Scotty is right on point.

  52. the whole point of using CFCs in mobile refrigerant systems to begin with was because it wasn't flammable, otherwise one could just use a proper mixture of LPG (AKA propane). Now they've come full circle but jacked the price up by 1000x

  53. I think the YF in the new refrigerant stands for
    You're F**ked……..
    We just got a new 2020 Chevy that has it in there. Now, I can't ever service the system if I needed to, like I could with the old R12 and even R134a systems.

  54. There are over a billion cars in the world. And 99% of the newer ones have A/C. And these numbers are only going to get bigger for the near future.
    So, even though each car leaks only "a little bit" of refrigerant, all those cars means their refrigerant has a huge impact on the environment. There are two environmental factors that apply to refrigerants. One is the Ozone Depletion Potential,. The other is the Global Warming Potential. Both of these values for R1234yf are much better than for R134a. That is why governments mandated manufacturers to switch to R1234yf way back in 2011. Yes, it would have been nice if it was practically inflammable. But then, neither is R134a, and neither are most of the materials in automobiles. Yes, it would have been nice if it wasn't so expensive. But then, you can expect its price to go down, and the price of R134a to go up, over time. Yes, it would have been nice if we didn't have to make changes every couple of decades. But then, I recall hearing similar complaints when they phased out leaded gasoline. You don't tell people to not buy cars which use unleaded gasoline. R1234yf is no different. The right decision isn't always the cheapest one, or the most convenient.

  55. It would make more sense to build the compressor and systems more robust. Stop useing cheep matterals.
    The main reason we are leaking refregerent is cheep
    HVAC parts. Looks like it would make more sense to put a window unit in our car with a high wattage inverter.
    I have a window unit I haven't done anything to in 60 years. Hell a window unit is heavy BUT !! IT LAST.

  56. They change from R12 because it had CFCs chlorofluorocarbon that's the thing that makes holes in the ozone layer supposably 134a doesn't have CFCs there's absolutely no reason for them to stop using 134a other than for the EPA people sitting in an office somewhere to write up some legislation to justify their jobs…… but if you think this is bad just wait till 2020 R22 that's the freon but everybody uses in their central air conditioners until just a couple of years ago it's all going away in the summer of 2020 so if your central air starts leaking you're going to have to just replace the whole damn thing I have a feeling you're going to see a lot of window units in the next 5 years
