So long as your refrigerant doesn't leak down you're fine. I've done thousands of air-conditioners and I'm not a fan of recharging because you don't know if you're low until you recover and weigh the refrigerant. So the procedure is recovering, measure and recharge. If you don't open the system you can just add 3 ounces of oil, but unless you open and clean the system don't add lots of oil.
I like the fact that you noticed it's the first comment. talegade-hombre is the first viewer to comment on this video and I thank him for it. Just for the record when dozens of comments accumulate on this video. Thanks.
1,1,1,2-Tetrafluoroethane is an inert gas used as a refrigerant for automobile air conditioners and both of these are the same. (HFC-134a) is to be replaced by a new refrigerant HFO-1234yf in automobile air-conditioning systems. California will also prohibit the sale of canned 1,1,1,2-tetrafluoroethane to individuals pretty soon. Mercedes Benz has had some objection to HFO1234, but looks to be the substitute.
Yes, no doubt about the dual parallel flow condensers. But the original issue is that R134 is less efficient at removing heat. It's just better for the planet. HFO1234yf (replacement for R134) is even better for the planet. I tend to think it'll be more efficient because it's a little flammable, but that's just conjecture on my part. Thanks so much for sharing. I welcome different points of view on my channel. That's how we learn.
No, I did not made a mistake. I started back in the 80's with R12 and probably did over four thousand retrofits. I'm also a Master ASE and L1 Advanced including the MACS HVAC certification. R134 is less efficient without a doubt, but better than R12 for the Ozone layer. Back in the R12 days we even had copper evaporators and ran fine. R134 evaporators have to be bigger and we ran into issues due to that, since the plastic housing was meant for a smaller evaporator.
You made a mistake with the R12 to 134A requirements: Evaporator does not need to be replaced. You must have meant the condenser. 134A cars have a more efficient parallel flow condenser. Also helps to run an extra pusher fan on the condenser of a converted R12 system for better cooling.
here in Australia we are using LPG it gets colder then any gas when compressd i regas my feroza with LPG and it gets -3 c it only takes 1 a couple of seconds and tye hole car is cold i like it
I have a Ford Expedition Medil 2003 and replaced by a New compressor works well and does not have a month after it was Czech cooled turned out he Fuse valid change after working for twenty minutes and then burning and valves on the Czech circuit , and there is no problem I do not know where the problemCan you help me
I have always heard that the high efficiency parallel flow condensers work much better than the early single pass units. In fact, they were introduced for use with R134 systems. Seems more relevant and necessary than the evaporator. Sorry, not trying to discredit you or question your credentials. God bless.
Diagram at 1.51 shows "liquid" leaving the compressor. Thought this would be a hot high pressure gas? Which is cooled and condensed to a liquid in the condenser.
I have a 2003 Mitsubishi Lancer ES. My A/C problem seemed to be when my car is at a stand still. I have 2 condenser fans motor and I have seen both of them turn on and off which tells me that they are working..... possibly not working right but at least I seen them clicking on and off? But when I'm driving my A/C is nice and cold. I mean really really good COLD air but once I stop the vent slowly starts to pull in some warm air. I do have experience in the HVAC (residential, commercial, and industrial) but I know auto A/C has the same principle but it is a little different as well compare to a home unit. I just hate to base my reading off of my gauges when in fact I probably have a air flow problem and don't wanna assume I overcharge the system, undercharge, or have a clogged system. I did investigate my condenser which looks to be in good condition and may be a little dirty which I'll clean shortly but nothing out of the ordinary. My question is what could possibly be the problem? The last thing I don't want is a clogged system but like I've said before my car has no problem at all cooling down when I'm driving. Any help would really be appreciated!!!
Also if you live in a higher altitude the air is less dense and the fans just running isn't sufficient enough to remove the heat. As you drive your allowing a higher volume of air move through your system.
2001 Hyundai Sonata - I thought at first it needed a recharge of R134a , it only took 1/3 of a can I noticed the clutch wasn't turning on the compressor , so what's next where are the high and low pressure switches located or the compressor cut off switch , I checked all the 10 amp fuses all good? if I check the resistance across the 2 wires coming out of the AC compressor clutch what should it read?
My ac was regassed by a professional. He checked everything. My ac still cuts out when the outside temp is really hot. We've been having 30+ degree Celsius days here. The professional guy who looked at it came back and still can't figure it out. Any options???
Very informative video, well done. Just wondering if anyone here can suggest with the situation I am having with my car. I have Mercedes W203 1.8 Petrol auto 2006 model. AC was running fine while I was driving and then I switched on the climate control which set the AC to full speed, I used it for 5 minutes and then turned off the climate control. After that AC stopped cooling. I refilled the gas twice also but still it doesn't blow cool air anymore, Can you suggest what part in the AC system is potentially not working here and how can I check it ?
if pipe of car Freon gas has leak because accident . what I should do ? . 1. remove belt of air conditioner 2. take off switch A /c . what i should do it to save my air conditioner . thank you
The design makes this AC a possible alternative to ductless DYI systems. It works great. The remote control could be more visual aid oriented like a backligh design. Is impossible to see the lcd at least for me. Easy install ruclips.net/user/postUgkx_hHgTlzH3uk31Fe2RVS3xEbXHGaN_z5Tation. Came on time . Great comfort around the house 5 🌟 again. Follow mfg instructions for care and all and this should be the only AC you need for those of is that don't live in new homes with central AC
the AC compressor is driven by a belt directly connected to the engine. this puts some, not alot but some strain on the engine, making your engine work more. same as hydraulic power steering.
Because when you turn on the AC, the clutch on the AC compressor engages and will use the turning power from the crankshaft via the AC belt to turn the compressor and as a result puts on a greater load on your engine. This puts more drag on your engine and consequently your fuel consumption.
+2phalanges Because the compressor that circulate the whole system is attached by a belt to the engine which causes extra gas consumption to run the car and the AC system. normal car battery cant keep up with demanded power the AC requires. EV cars and some Hybrids use battery powered AC systems because of the enormous rechargeable battery these cars have.
This video is terrible and should either be fixed or taken down to avoid confusing readers. It is not only backwards in function and operation but also contains a gross error. In 1:50 seconds into the video, someone hand sketched a flow diagram that is incorrect. The flow diagram shows liquid at compressor OUTPUT and its input being a Hi-pressure, high-temp gas at input side. 1. CAD layout annotation of compressor hi / lo ports vs. hand drawn flow diagram found in 1:50 - backwards thus showing reversed port flows. 2. Involves hand-annotated flow diagram showing output side as being a low-pressure liquid output. This is wrong / incorrect. Compressors can't compress liquid / fluid. Both sides (Hi & Lo) involve gas. One is lo-pressure incoming gas while the output section is the compressed gas at high-pressure and at high temperature. This video is incorrect and is going to confuse readers.

Very good video. How to test the refrigerant leakage and locate the leaking point?

Do the fans in your radiator work?
It seems like that both of the fans are busted.
A leak on prion
Also if you live in a higher altitude the air is less dense and the fans just running isn't sufficient enough to remove the heat. As you drive your allowing a higher volume of air move through your system.
The coefficient of performance in the Automobile Air Conditioner when n=1940 r. p. m. Is greater than or less than n=2900 r. p. m?
Don't know
Actually, R-134A is more efficient given you have correct and properly working components.

if I check the resistance across the 2 wires coming out of the AC compressor clutch what should it read?
Rondo Schiavoni You could have air in the system. Evacuate, vacuum and recharge first. Otherwise you go out on a goose chase. Good luck.
Thank you
Thanks was over charged
So how often should you recharge your AC and oil the compressor?
My ac was regassed by a professional. He checked everything.
My ac still cuts out when the outside temp is really hot. We've been having 30+ degree Celsius days here.
The professional guy who looked at it came back and still can't figure it out.
Any options???

excellent video...may i know the latest i.e in 2014 refrigerant used in the cars.
They're all different. You'll need to look at the specs.
Mostly R-134A.
The blower doesn’t blow air across the evaporator, it pulls air across the evaporator

Cool
The year for the switchover is wrong as my 1995 Chrysler has R134a.
Thank you sir for sharing...!
Thank you sir , for sharing
I appreciate that...
stupid question, how come using the ac uses so much gas, instead of battery power?
the AC compressor is driven by a belt directly connected to the engine. this puts some, not alot but some strain on the engine, making your engine work more. same as hydraulic power steering.
Because when you turn on the AC, the clutch on the AC compressor engages and will use the turning power from the crankshaft via the AC belt to turn the compressor and as a result puts on a greater load on your engine. This puts more drag on your engine and consequently your fuel consumption.

EV cars and some Hybrids use battery powered AC systems because of the enormous rechargeable battery these cars have.
+2phalanges Because what powers the compressor is the engine with the serpentine belt and not an electric motor.
+2phalanges Because your motor is running the compressor via a belt. The compressor doesn't run on battery power, its not an electric motor.
Thanks
