When you said "it'll take a while" you weren't kidding! The whole process took my car over 30 minutes before the can emptied. When I began I almost gave up because the gauge wasn't moving and the can felt full, but patience paid off and it eventually took the whole can. I still have a bit further to go on my gauge, but my car is blowing very, very cold air!! Thanks for a good video with important tips. Also, many comments here ask what the pressure should be when full. On my gauge it says between 45 and 65, but others tell me full is between 40 and 50. I got mine to 40 before the can emptied and my a/c is much, much colder. I'm going to wait a few days to see if it leaks out, and if the temp remains steady I'll buy another can to top it off.
I have watched dozens of similar instructional videos and you are the only one who correctly vents the fill hose line once it is connected to the low side port by slightly unscrewing the can. This is a very important procedure as it keeps moisture and air from entering the system.
Well done! I went to Canadian tire and the price was over 70$ plus the tax for 2 cans of refrigerant along with a hose and gauge...walmart was 50$ along with a hose and gauge and a local mechanic was 100$!!! I got on my bicycle went to the auto parts store got a can of refrigerant along with a hose 37$ and this gentleman wants a... like ...and a simple thank you! Keep it up!
Great video but could have touched on the pressure gauge during the process. After its initial showing you never showed any pressures during the process, this would have helped to understand it more. How did you know you were at the stopping point? Thanks
@@knowgo411 Another bad video, dude you didn't show when to stop at what level on the GUAGE 120 or 110 ? Wth man another video i've watched kinda bad , also was your Car windows up or down the whole process ?
The hose kit should tell you at which point to stop. Mine has a yellow area at the 12 'o clock mark showing when it's full. Check the mfgr instructions.
The pressure gauge is the most important part and you skipped it, The gauge pressure should tell you how much Refrigerant gas is still in the AC system, and as you are filling the refrigerant gas it will tell you exactly when to stop filling as you reach the right pressure . I appreciate the slow explanation for everybody to understand but wish you explained the pressure gauge role in this process.
Well done video! My only critique is that you should have shown the needle climbing on the pressure gauge, and talked about the specific PSI (found on a under hood sticker or online) of the vehicle you were working on. As for the critics that complain about you overexplain the procedure ...they should realize that mostly noobs like me are watching this...when it's over 90 degrees!!!
You used a clear and concise terminology to describe the steps to take for the addition of coolant to the A/C system. Anyone who hasn't done this operation should have a much better idea of what it is that they are doing. I was a bit disappointed in the fact that the gauge needle position of a fully charged system wasn't indicated, but the instructions provided with the gauge assembly should cover this. You produced a fine video that should help those who are not familiar with adding coolant to the automotive A/C system. You performed a service that should help people who may not have extra funds to spend, get a bit of relief from the heat that the Summer months hammer us with. You didn't cover all aspects, but between what you have provided and the instructions on the can and gauge assembly, someone can get a little comfort. Thanks for taking the time to help others that may need a little bit of information to get through the heat of driving around in summer traffic.
One thing I have done since the mid-'70s is to set the charging can in a 2qt saucepan full of very hot water once it begins to empty. This little trick makes the can empty in less than half the time by increasing the pressure in the can. As the can empties it gets very cold because that is what it is supposed to do. But the colder the can gets the longer it takes to empty.
From S. Korea, A great wonderful guide for my AC recharge DIY. Furthermore it is very simple and clear for me. Eventhough I'm not native English speaker I could follow your tutorial explain easily. Not only systematic but also articulate for me.
I am not a mechanically inclined person, but your video gave me enough confidence to give it a shot tomorrow. Very clear for the novices like me. Thanks.
Glory to God! I can’t begin to tell you how much I appreciate this video. I have been looking for days and I finally found someone that gives detailed step instructions one 12 oz can. And which end of the holes goes to the can vs into the car😅. Like a woman should know these things? Not really😢. Very grateful thank you so much.
The pressure reading should be around 35 psig, but that is an approximation , it really depends on the outdoor (ambient) temperature ....Some of the dials on the gauge spin so you can set it to the outdoor temp and then you can set the charge.......If you buy one they should come with instructions on how to do it.............hope this helped.... The proper way to do it would be to weigh it in as per the sticker in the engine compartment or owners manual....
Me too! Sorry but this is the worst car AC video i have seen why do you have a gauge at all just use a straight hose hahaha man go learn how to do a proper video or don't do them at all that gauge is very important on the refiling of the ac you did a blind video for the viewers ,i know your intentions are good but not good enough .
If your not in Canada it's different, they cant cant get R-134 so that got to use that bullshit that hopefully don't explode if it gets a leak. In America that shit is illegal I think, can't put anything flammable in a car AC but if you buy a gauge like that it will come with instructions, a lot of of the little cheap ones have a thing where you spin the outside of it depending on the outside top and it will have a green and yellow and red
Great instructional video. I used the REDTEK 22A "residential" kit to repair my Home AC (3ton) system. The only thing I would add is it may be useful to use a can of their "leak sealer" before recharging with refrigerant. (its done following the same procedure as you have explained in the video. Except don't rely on the gauge. ) Surprisingly, the DIY kits work really well and will save hundreds of Dollars. Bought mine at CanadianTire (in Canada)... Again great video.
I liked the way it was explained. Slow and precise. However I would have liked it more if that gauge or meter was explained. How it is usedand what one should look for.
Great video man, you saved me,lol,as I first went by Red Tek instructions, turned the can upside down, what b.s .,almost used a full can 4 nothing. But then followed your instructions and everything worked out,now have cold ac in my old 2005 Accord!
Great video! I used your instructions to fill up my car's AC during my work lunch hour. I bought the refrigerant through Amazon and my dad had a leftover hose gadget that he bought from Canadian Tire (the same one in the video).
@@bigskill80 If you live in Canada, look for Red Tek AC Refrigerant Recharge Kit. I'd do more research on your own to decide whether to use R134a or R12a coolant. Personally I used R134a on a 2005 Mazda 3.
Ur Explanation is a master piece my friend.....only the gauge thing....for those who didnt understand...and are winning about the video.....start school again...
For those asking about the gauge, which the good poster overlooked to show. The proper recharged pressure is around 40 PSI, plus or minus 10 PSI. This is the blue region, which is usually marked 25 to 55 PSI. Once it reaches about 40 PSI, there is enough gas, and you can close off the tap on the can. The aircon should be cold enough. Look also at the sight glass on the receiver-drier. Enough gas usually shows clear liquid, or few bubbles. More bubbles usually means not enough. You can also touch the suction pipe (where the refill valve is) coming out from the evaporator, and onto the compressor's low suction port. This should feel cold, or fairly cold, as the compressor cuts in, after about 15 to 30 seconds.
Well explained, thanks very much. ---- How long did you leave refrigerant filling into the car, and what's the reading on the meter? You said it takes a while
You forgot to explain that the gauge should have a dial to adjust based on ambient temperature. And that pressure readings should be observed when the compressor turns on.
Just FYI - 12a is ozone friendly and more efficient than the 134a = also - there's a reason why it ran dry - there's a leak - u should use a sealer for fixing - THEN put the coolant in
Nice report thanks, two questions, most vid's say never Overfill the AC system it could damage the unit? I would have liked to see your gauge readings. Two, the can gets super cold, & freeze you, should use gloves? I know this is true from experience? What say you?
Nice vid... Id like to add a few things... 1 prior to charging the system its best to leave doors open so that the clutch will stay engaged.. If clutch is disengaged you will get a higher reading.. You want a reading of 30-38PSI anything over 60 PSI can damage compressor. (On compressor pulley there is a 2nd wheel in the middle which spins... That is the clutch engaging while spinning you watch you reading) Also... I dont know why you would have the gauge facing the other way and informing people to fully open valve then agitate.... You invert the can then slowly open the valve while watching the gauge so you dont overcharge... Once you hit 30 close the valve... No need to crack er open, a split second late and you dicked er. 3rd this is just a bandaid... 4th prior to charging the system its a good idea to check for leaks.... Or of you don't want to, run the red tek ac sealant through it... Over time o-rings shrink/harden where you could use redtek leakstop Other leaks happen in metal and rubber lines, the condenser etc.. You would use redtek proseal. If youve achieved the proper charge (30-38psi) and the can still has refridgerant in it... DO NOT REMOVE THE CAN FROM THE CAN TAP HOSE VALVE!!! Leave attached to hose and store....
Thank you. I was wondering about the tap valve and remaining refrigerant as I do not want to overfill my car nor lose such an expensive product to the atmosphere - for environmental and monetary reasons, of course.
Warning: He does't show to measure pressure BEFORE adding refrigerant, and he doesn't show the "proper" measurement on the gauge AFTER he's added refrigerant. That's very important. If you add a whole can but needed only part of it, your compressor could be damaged.
Very helpful, and the slow and precise route is the way to go for us utube mechanics! Yes he didn't mention the gauge range but it is pretty self explanatory and your ok to keep it in the GREEN range...colour coded.
Hello that I don't understand, is why when you connect the hose, the gauge shows 130psi ? And the engine is not turning. I know when the compressor on the AC is ON, you should get 20kg/cm2 = 285psi. How do you proceed to bring the needle in the blue arc, ususally between 50 and 60 psi for a car with R134a gaz ? Many thanks for answering, all the best.
You know you’ve reached the required level once you’ve been recharging for a while.. just a while… no quantifying that statement. It will just feel like a while
I need help. Right when I backed off the valve to release trapped air like you did in video my guage was still in the red reading 90psi. I noticed your gage read high to but need your help. Is the guage suppose to 0 back out before turning car on or what?
Would you be able to film this again having arranged your guage so everyone can see how the progress goes. All I could tell is your guage puts the normal zone a bit higher that most people say it is. All these things are important. But filming again would be useful especially after 4 years of people observing that you didn't show anything most important.
Safety measures should be applied, Safety Glasses, gloves to protect against frost bite. As remarked elsewhere a visual of the gauge would have created better instruction to this video. It was nice and slow with most detail.
NICE THE WAY YOU EXPLAIN, I HAVE TAKEN H.V.A.C. FOR TWO YEARS AT THE SEQUOIA TECHNICAL INSTITUTE, FREMONT, CALIFORNIA. I COMMEND YOU FOR YOUR THOROUGH EXPLANATION, SIMPLE STEP BY STEP, EASY TO FOLLOW AND UNDERSTAND IN A FORM OF TUTORIAL APPROACH IN ''HOW TO DO IT YOURSELF'' FOR THE B E G I N N E R S AND N O V I C E.

I did it! Thank you! I first saw your video three weeks ago, it took me this long to work up the courage, and today I figured it out. Couldn't have done it without you. Thanks!
You’re a nerd and shouldn’t even own a vehicle. Shut up. The gage should be in the blue, it’s common sense moron. Also go ahead and wear safety glasses like a meathead. I won’t be
I found this really helpful. I'm not a car person at all, all I know how to do it change a tire and check oil lol but I did this all by myself after watching this video!! Thanks!
This is a "how to top off your refrigerant" video at best. They sell these types of products with the gauges already built in. Refilling refrigerant takes a lot more prep than this, such as having a pump and manifold gauges, both of which you can rent out from AutoZone (for example), and you would really only ever need/want to do this if there is a serious issue or you just replaced your compressor
+James Staton He's probably in canada, they cant just buy 134a off the shelf so they have that dangerous alternative that is illegal in the USA. Its highly flammable
@@followtherabbit203 it can also click on and off. if the clutch kicks on and the pressure drops too low, then turns off and it goes into the red, that means it's low. If the clutch turns on and goes into the red, that means it's overcharged.
Two thumbs up!!! Thanks for the step-by-step tutorial, awesome~ btw, I'm wondering if I can use any kind of refrigerant regardless of make/model? I guess 134a will work for my Honda Civic 2009. Thanks for the video~~ ☺
If you pop the hood of your car, there will be a sticker, saying which a/c refrigerant your car uses. Most cars will require 134a, very old cars (e.g. 1970s) will need R12.
Were the gauge readings some sort of a secret? You kept the dial facing away from the camera. One of the main questions is the gauge readings. Useless video without showing everything.
I don't trust anything under pressure. After watching your video I can't wait to tackle mine. Thanks for the confidence and motivation boost. The gauge wasn't much of an issue, I figure that would give me the opportunity to read and get that info from the instructions that came with my kit anyway. 👌👍🏼
dude. best video on doing this that i found. I love your describing every detail. things other videos just glossed over. and thanks for enunciating every word. I appreciated that as well. GOOD VIDEO!
OMG! This is the first video where the instructor doesn't show the gauge and the irony of this is that he explains this very well. He tells us how to put and remove the can, period!
It was an empty can he had previously filled it cuz you can see in beginning pressure was perfect just showing how to do it.A guy like this always has his stuff already done
Exactly. Good tutorials must explain every step in clear and concise language, which means slowing down a bit. The only real flaw in this one is not showing the meter gauge and how to compensate for outside air temps as to proper reading.
Hello, I have a question. I just tried to fix my airco in my Kia Picanto 2012 with one of those simple kits with a can of refrigerant, and a hose with a gauge. (mine did not come with a temperature setting). My airco had just gradually become less cold over the years and now it had completely stopped working. I was hoping for a quick fix for now, but it didn't work out so far. When I connected the kit with the gauge to the low pressure side, it showed no pressure at all. Then I filled it untill it showed 60 PSI, with the engine and airco on. (was aiming for 50 but gone a bit too far). After that I drove around the block and when I drove away, cold air was coming out of the vents, and I thought it was a succes! but.. this only lasted for a very short time, a minute or so. (that doesn't sound too good, right) So now the airco still doesn't get cold. Now, when I check the pressure on the low pressure side, the gauge shows 60 PSI, engine and airco on, or off, there is no difference. Also, the pipes don't feel cold at all. Since it is also showing 60 PSI with the airco and engine off, I'm thinking... maybe there is still not enough pressure, because with the airco off, the pressure should rise far into the red zone... (like 100 PSI) if i'm right? Do you think it's worth it to try and get another can of refrigerant, to build up the pressure and see if the airco will actually activate? (I can't seem to spot any compressor pulley turning on and off when I turn on and off the airco, everything seems to be turning always, even with the AC button off. But the fan on the front of the car does turn on and off with the AC button.) (one more thing. I was too quick to do it, and kind of forgot about the temperature thing. I think it was about 68 degrees fahrenheit here when I filled it.... So according to the temperature/PSI charts, according to that I should have filled it to about max 35 PSI... and I filled it to 60 PSI.... So Im kind of worried that I have destroyed my AC system. But, since it's also showing 60 PSI with the engine and airco off... I doubt this, and start thinking the pressure is actually too low? I hoping you could shed some light on this!
You need to purge out moisture or air inside the two hoses. That is tricky since the manifold gauge is not provided with the valve to enable the purging 😅
Everything was fine but you missed the low pressure reading & on some cars you can use an ODB2 adapter & the Torque App with a custom PID to read the high pressure side PSI.
Thanks for the walk through. Try not to repeat everything you say. It would have helped a bit if you would have actually recharged your system and compared gauge before and after
First off never mix refrigerants NEVER. Your adding r12a to a r134a system r12a was made to retrofit old r12systems 2nd you should be using proper gauges hi and low side you can get a set for under $50 looking at both high and low will let you know if it is low or you have another problem like bad txv or accumulator just adding refrigerant is an amature move and your putting out bad information there’s a reason hvac techs are well paid
This is by far THE BEST video showing us how to refill the ac system with refrigerant. There are ao many quick videos but they lack detail. Thank you so much for the video man

Hmm you keep the gauge reading between 40 to 50.
This is the best DIY recharge tutorial I've found on RUclips for beginners. Detailed and not overly hurried like others are.
Why you are charging the car AC with a 12A freon can ?
I have watched dozens of similar instructional videos and you are the only one who correctly vents the fill hose line once it is connected to the low side port by slightly unscrewing the can. This is a very important procedure as it keeps moisture and air from entering the system.
This is why the actual proper procedure is to us a vacum while doing this
The official instructions I got with my housing kit didn't even mention it. Guess that's made in china for you.

You invert the can then slowly open the valve while watching the gauge so you dont overcharge... Once you hit 30 close the valve... No need to crack er open, a split second late and you dicked er.
3rd this is just a bandaid...
4th prior to charging the system its a good idea to check for leaks.... Or of you don't want to, run the red tek ac sealant through it... Over time o-rings shrink/harden where you could use redtek leakstop
Other leaks happen in metal and rubber lines, the condenser etc.. You would use redtek proseal.
If youve achieved the proper charge (30-38psi) and the can still has refridgerant in it... DO NOT REMOVE THE CAN FROM THE CAN TAP HOSE VALVE!!! Leave attached to hose and store....
I don't know about "nice vid", good try maybe. Anyway, you just saved me a lot of typing, thanks.
Inverting the can puts the liquid side towards the hose. Isn't that wrong? Should he have closed the tap valve on the can to get a good reading?
Thank you. I was wondering about the tap valve and remaining refrigerant as I do not want to overfill my car nor lose such an expensive product to the atmosphere - for environmental and monetary reasons, of course.
Your video is the first of many vids on this to show a way to evacuate some of the air in the tube before piercing the can. Thanks.
Warning: He does't show to measure pressure BEFORE adding refrigerant, and he doesn't show the "proper" measurement on the gauge AFTER he's added refrigerant. That's very important. If you add a whole can but needed only part of it, your compressor could be damaged.
That is understandable . I don't mind him skipping. Any normal person should check befor e, after since the hose has gauge , just like tire pressure.
I would suggest eye protection--like plastic goggles of some kind.
He didn't show the measure or check 🤔 how much did he put or need it
As long as you keep the needle in the blue zone of the gauge you are fine it's not rocket science
U r really awesome my friend, esta chido tu video 😎
Very helpful, and the slow and precise route is the way to go for us utube mechanics! Yes he didn't mention the gauge range but it is pretty self explanatory and your ok to keep it in the GREEN range...colour coded.
You should show the pressure on the gauge, otherwise an excellent video.
You should of showed us the Gauge has you were charging the car , that is the main point to show !
Hello that I don't understand, is why when you connect the hose, the gauge shows 130psi ? And the engine is not turning. I know when the compressor on the AC is ON, you should get 20kg/cm2 = 285psi. How do you proceed to bring the needle in the blue arc, ususally between 50 and 60 psi for a car with R134a gaz ? Many thanks for answering, all the best.
What is the required level of refrigerant reading on the meter? Or is the amount different based on your car specifications?
You know you’ve reached the required level once you’ve been recharging for a while.. just a while… no quantifying that statement. It will just feel like a while
@@anthonygonzalez5835 Thanks
I need help. Right when I backed off the valve to release trapped air like you did in video my guage was still in the red reading 90psi. I noticed your gage read high to but need your help. Is the guage suppose to 0 back out before turning car on or what?
Would you be able to film this again having arranged your guage so everyone can see how the progress goes. All I could tell is your guage puts the normal zone a bit higher that most people say it is. All these things are important. But filming again would be useful especially after 4 years of people observing that you didn't show anything most important.
thanks you.. really helpful seeing your video for me as independent woman..🇲🇾
Safety measures should be applied, Safety Glasses, gloves to protect against frost bite. As remarked elsewhere a visual of the gauge would have created better instruction to this video. It was nice and slow with most detail.
What is the brand name of the can tap with pressure gauge assembly you are using?
NICE THE WAY YOU EXPLAIN, I HAVE TAKEN H.V.A.C. FOR TWO YEARS
AT THE SEQUOIA TECHNICAL INSTITUTE, FREMONT, CALIFORNIA.
I COMMEND YOU FOR YOUR THOROUGH
EXPLANATION, SIMPLE STEP BY STEP,
EASY TO FOLLOW AND UNDERSTAND
IN A FORM OF TUTORIAL APPROACH IN
''HOW TO DO IT YOURSELF'' FOR THE
B E G I N N E R S AND N O V I C E.
THANK YOU SIR, I RECOGNIZED
YOUR P R O F E S S I O N A L I S M.
I REALLY APPRECIATED THAT....;)
Are you not suppose to empty the system before adding ?
Yup..
I'm just sitting here wondering why you need to hold your camera tripod.
Blessings to All,
and to All a Joyous Day🙏
ive watched very many videos on this,
and by far yours is the most informative giving me the extra courage that i needed to do my own, you are truly a gifted presenter, a teacher from the your Heart,
with Love and Appreciation,
william and familia🙏👨👩👧👧💞
I did it! Thank you! I first saw your video three weeks ago, it took me this long to work up the courage, and today I figured it out. Couldn't have done it without you. Thanks!
need to have enough oil in lines
How long is a while? 5,10,15 or 25 minutes. Or leave in connected and running on max ac until the can is empty. Thanks.
OMG I have learn a lot from this video. I learn not to wear safety glasses n gloves. N I learn to look at the back of the gauge. Thank you very much.
You’re a nerd and shouldn’t even own a vehicle. Shut up. The gage should be in the blue, it’s common sense moron. Also go ahead and wear safety glasses like a meathead. I won’t be
I found this really helpful. I'm not a car person at all, all I know how to do it change a tire and check oil lol but I did this all by myself after watching this video!! Thanks!
This is a "how to top off your refrigerant" video at best. They sell these types of products with the gauges already built in. Refilling refrigerant takes a lot more prep than this, such as having a pump and manifold gauges, both of which you can rent out from AutoZone (for example), and you would really only ever need/want to do this if there is a serious issue or you just replaced your compressor
Absolutely educational, thanks for your time, effort and kindness to share this valuable information. It's truly a cost saver!
You specify in your description that the refrigerant used is R134a, but you are using R12a in your video. The filling processes are different.
+James Staton He's probably in canada, they cant just buy 134a off the shelf so they have that dangerous alternative that is illegal in the USA. Its highly flammable
are you guys nuts? 134a is what we use! thats what you get when you buy a recharge kit because of the few hazards associated with 12.
Under that good, tells you what type of refrigant to use.
Great video , May be we have to do the dye can first to seal the leak ?
Very clear and slow step by step video. However, it did not show the gauge for the pressure.
Good job ! Thank you !
How do you know what temp it's supposed to be at? Is it the same for all cars?
also when you start the engine make sure the the compressors clutch engages
Nice shoes Mike.
If the system is low on Freon the clutch will not engage
@@followtherabbit203 it can also click on and off. if the clutch kicks on and the pressure drops too low, then turns off and it goes into the red, that means it's low. If the clutch turns on and goes into the red, that means it's overcharged.
Not showing pressure Gauge numbers has ruined your video .
What pressure did you stop regasing at and what pressdure did you start ?
When he hooked up the hose if you looked at the gauge it was in the blue already I guess it was already full.
I am writing to you from Greece. How is it possible to show this video without showing and explaining through the lobby what exactly needs to be done?
Two thumbs up!!! Thanks for the step-by-step tutorial, awesome~ btw, I'm wondering if I can use any kind of refrigerant regardless of make/model? I guess 134a will work for my Honda Civic 2009. Thanks for the video~~ ☺
If you pop the hood of your car, there will be a sticker, saying which a/c refrigerant your car uses. Most cars will require 134a, very old cars (e.g. 1970s) will need R12.
@@dizheller2101 Beautiful~ Thank you so much!! ♥
Don't u have to vacuum it out first n then recharge?
Were the gauge readings some sort of a secret? You kept the dial facing away from the camera. One of the main questions is the gauge readings. Useless video without showing everything.
If I have to recharge many cars, is it cheaper to buy small cans like this instead of a bigger cans that comes with a adapter?
I don't trust anything under pressure. After watching your video I can't wait to tackle mine. Thanks for the confidence and motivation boost. The gauge wasn't much of an issue, I figure that would give me the opportunity to read and get that info from the instructions that came with my kit anyway. 👌👍🏼
Xxxxxcx 🙎
what's the purpose of the big blue round thing with the two little screws? Do i need that?
dude. best video on doing this that i found. I love your describing every detail. things other videos just glossed over. and thanks for enunciating every word. I appreciated that as well. GOOD VIDEO!
Thanks for the detailed description on how to recharge the air conditioner. Very helpful. 😊
OMG! This is the first video where the instructor doesn't show the gauge and the irony of this is that he explains this very well. He tells us how to put and remove the can, period!
The pressure gauge is self explanatory 🤦♂️🤦♂️🤦♂️🤦♂️🤦♂️😆.....
Please explain the gauge that was attached to the hose.What should be the pressure reading I.e. before and after you charge?Thanks.
Thanks for for keeping us guessing by hiding the gauge…
I am also wondering if R12A can be used directly in R134A system like my 2010 Toyota 4runner?
Purpose of the gauge, show your readings before, during ,after.
The way you did it, just use a hose w/2-couplers!
7:08 what’s is the appropriate number for the refrigerant ?
It was an empty can he had previously filled it cuz you can see in beginning pressure was perfect just showing how to do it.A guy like this always has his stuff already done
Best AC video on RUclips,thanks brother
Kernt thee frog here... Good video.
I thought it was George McFly.
Very informative podcast 😅
Great vid with clear instructions. My A/C is now blowing winter! Thank you, sir.
Thank you for the video, but i don't know why you don't show us the pressure gauge?
This duffs must be a Kindergarten teacher, talks as if he is talking to a child. Thanks Mr Rogers
I noticed
I moved here from Canada, and they think I'm slow, eh!
(Simpsons reference for you)
Stop being a jerk. He was nice enough to take his time to do something that YOU need help on
Exactly. Good tutorials must explain every step in clear and concise language, which means slowing down a bit. The only real flaw in this one is not showing the meter gauge and how to compensate for outside air temps as to proper reading.

Hello,
I have a question.
I just tried to fix my airco in my Kia Picanto 2012 with one of those simple kits with a can of refrigerant, and a hose with a gauge. (mine did not come with a temperature setting). My airco had just gradually become less cold over the years and now it had completely stopped working.
I was hoping for a quick fix for now, but it didn't work out so far.
When I connected the kit with the gauge to the low pressure side, it showed no pressure at all. Then I filled it untill it showed 60 PSI, with the engine and airco on. (was aiming for 50 but gone a bit too far).
After that I drove around the block and when I drove away, cold air was coming out of the vents, and I thought it was a succes! but.. this only lasted for a very short time, a minute or so. (that doesn't sound too good, right)
So now the airco still doesn't get cold.
Now, when I check the pressure on the low pressure side, the gauge shows 60 PSI, engine and airco on, or off, there is no difference. Also, the pipes don't feel cold at all.
Since it is also showing 60 PSI with the airco and engine off, I'm thinking... maybe there is still not enough pressure, because with the airco off, the pressure should rise far into the red zone... (like 100 PSI) if i'm right?
Do you think it's worth it to try and get another can of refrigerant, to build up the pressure and see if the airco will actually activate?
(I can't seem to spot any compressor pulley turning on and off when I turn on and off the airco, everything seems to be turning always, even with the AC button off. But the fan on the front of the car does turn on and off with the AC button.)
(one more thing. I was too quick to do it, and kind of forgot about the temperature thing. I think it was about 68 degrees fahrenheit here when I filled it.... So according to the temperature/PSI charts, according to that I should have filled it to about max 35 PSI... and I filled it to 60 PSI.... So Im kind of worried that I have destroyed my AC system. But, since it's also showing 60 PSI with the engine and airco off... I doubt this, and start thinking the pressure is actually too low?
I hoping you could shed some light on this!
You need to purge out moisture or air inside the two hoses. That is tricky since the manifold gauge is not provided with the valve to enable the purging 😅
He purged.
2:35 i have the same reading of gauge is that normal? Even I didn’t open the can yet, that’s why i stop it and search some videos.
My friend, we did not see the amount of gas filled and did not see the scale of the filling gauge .... I am surprised at you ...
Everything was fine but you missed the low pressure reading & on some cars you can use an ODB2 adapter & the Torque App with a custom PID to read the high pressure side PSI.
Thanks for the walk through. Try not to repeat everything you say. It would have helped a bit if you would have actually recharged your system and compared gauge before and after
Wouldn't turning the can upside down make it easier to push the refrigerant in?
First off never mix refrigerants NEVER. Your adding r12a to a r134a system r12a was made to retrofit old r12systems 2nd you should be using proper gauges hi and low side you can get a set for under $50 looking at both high and low will let you know if it is low or you have another problem like bad txv or accumulator just adding refrigerant is an amature move and your putting out bad information there’s a reason hvac techs are well paid
He sells A/C compressors.
Is there even a high side port to tap into?
This is by far THE BEST video showing us how to refill the ac system with refrigerant. There are ao many quick videos but they lack detail. Thank you so much for the video man
semble assez bien expliqué parcontre je recommande de regarder plus que 1 video merci!
Great video! Gloves and glasses for safety should be recommended
