HTML-код
- Опубликовано: 30 июн 2024
- In this video, I show you how to refill your AC refrigerant in your car. This tutorial is specifically for the R134a type of refrigerant that newer use. It is a simple process and can be done by any DIYer that puts their mind to it. You should definitely check the R134a pressure that is required for your car before starting the process.

Dude. You showed me how to shake the can for 5 mins but not once did you show us the gauge for the proper pressure!!! The most important part!!!
He did mention that he checked the gauge to make sure it was on the right level. The gauge is self-explanatory.
+Rachel Marlow he never shows us the gauge and what level of pressure It's supposed to be at. Key info.
You will understand when you see the gauge, you really can't screw it up.

Hmm you keep the gauge reading between 40 to 50.
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.
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!!!
Well put. Exactly my comment as well.
all cans have red if you smart you dont touch go to the red! keep between 45 and 55psi @@bobbymak6964
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!
Mechanic would have used a scale and bled the whole system, more money but better process if you want your ac to last more than one more summer
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.
since the beginning i was hoping and awaiting to see the meter readings....but you simply killed my dreams.
Haha I was wondering the same
I was wondering the same this's stupid
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....
OMG yes!
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 .
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
Yes excatly my question aswell!...(other than that he did a great video)
@@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.
@@officialyashvirgaming My gauge says Full is between 55 and 65. It's like that on another hose kit a friend has too.
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.
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.
I just wanted to ask the same question
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.
No problem at all! Thank you very much for the comment!!!!
William Charles - Well said. Great video, my only c/o was the gauge calibration(s). ✌️
blah blah - painful to watch and listen too - like old people eating -
LMFAO
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!
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.
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).
What's the proper name and cost of that gauge? Thank you
Does it need a specific type of refrigerant can?
@@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.
@@trollking99 .
Very clear and slow step by step video. However, it did not show the gauge for the pressure.
Good job ! Thank you !
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.
Since he hides the guage...Quick tip....Put thermometer in Vent...when the temp is 40°-45° ur good....DO NOT OVERCHARGE
Yes! For years I didn't have a gage. Add slowly and stabilize at 40 45.
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.
I have a video that may help u. Very descriptive
+Leekautorepair does this apply to any car?
After making a big deal about the meter you did not show its face during its most important time, when the charge is complete. Disappointing!
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
all we use in canada is 134a.
Dilip Saraf
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.
When you opened up the can your guage indicated almost in the red and you turned your guage away. So what is the correct pressure.
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.
thanks for hiding the gauge all the time.
Haha
Hahaha,,,,,,,,
Michael Owens yeah lol this guy is a dumbass
😂😂😂😂
🤣🤣🤣🤣
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
Great video , May be we have to do the dye can first to seal the leak ?
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 🙎
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 ?
lol thats what they use
@@khoivu7508
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!
I did it step by step thanks for this knowledgeable contribution ❤
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!! ♥
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.
the compressor is forced to run constantly. It will run full or empty
@@harryjones2420 is wrong. if it's empty will not run well, it will stop and run and it will very difficult to read the gauge.
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?
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
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 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....
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?
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...
Thanks for the information thanks again just want to ask for how long ikeep chasing the bottle
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
Coolant 😂😂😂😂😂
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
Thank you Sir. After watching so many videos you were the only one could answer my question and to give me the help I need! 💕❤
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🙏👨👩👧👧💞
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
You should of showed us the Gauge has you were charging the car , that is the main point to show !
Wow - vastly superior to other do-it-yourself videos on RUclips!
👏👏👏
thanks, no matter how common knowledge it seems it is great video as it is not actually common knowledge to all, great job very descriptive, I'm new to your channel but I bet you have a bunch of descriptive videos
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
Thanks for for keeping us guessing by hiding the gauge…
Please explain the gauge that was attached to the hose.What should be the pressure reading I.e. before and after you charge?Thanks.
Thank you so much. I did put refrigerant in my 2013 honda civic for the first time and I did it nicely after watching your video. with the help of guage you cant overfill or law fill. awesome.god bless you.
semble assez bien expliqué parcontre je recommande de regarder plus que 1 video merci!
Why the gauge is not visible during charge most important ?
Great job on the instructions!!
A lot of people are asking about gauge reading. The low side, on the gauge, is blue and the high side is red. You are filling from the low side so when your gauge reads anywhere in the blue that is good.!
So what was the pressure gauge for?
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
Thank you for your video, it's helpful.
Thanks for the detailed description on how to recharge the air conditioner. Very helpful. 😊
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.
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
Waited & waited for gauge info. Thats the
Most important part.....
great video, showing the gauge reading would have been good
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.
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

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....;)
Thanks for the tip about releasing the air from the hose.that really helped
To helpful diy thanks the good tip on the ac refill you never learning thanks again my friend
Purpose of the gauge, show your readings before, during ,after.
The way you did it, just use a hose w/2-couplers!
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 🤦♂️🤦♂️🤦♂️🤦♂️🤦♂️😆.....
thank you very much , i did learn ,very helpful
you never did show the gauge functions, before and after. you can hold can upside down to make sure it is empty. thank you for video
WRONG! You did not show the Measurement Gauze the whole process of refilling the system. You did not even check the level after refilling
Great vid with clear instructions. My A/C is now blowing winter! Thank you, sir.
thx a lot for shering this video.. now l am going to try to do this by myself .. seems its easier tht l thougth l wont pay to much money to refill my freon up
santiago juarez b
good video but what's the appropriate gauge for the refrigerant
When he hooked up the hose if you looked at the gauge it was in the blue already I guess it was already full.
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.
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.
Guess the pressure...lol nice tutorial very informative...
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.
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.
Thanks great video 👍🏻
Thanks you for the teaching 😀
I'm just sitting here wondering why you need to hold your camera tripod.
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
I still have no idea how to use a guage or how much refrigerant to administer. Off to find another video, thanks.
What is the brand name of the can tap with pressure gauge assembly you are using?
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.
Kernt thee frog here... Good video.
I thought it was George McFly.
Very well said sir.thank you
The best video thanks for uploading💯💞
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
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!
More efficient to make the air from the tube .so good 👍 information
EXCELLENT "D. I.Y. Video".
HOWEVER...@ ~7:00 (minutes), how and/or when do I know how to calibrate the PROPER psi {on the gauge}, specifically for my vehicles❓
I understood the dexterity of the procedure...but, being a complete Motor Mechanical Moron, it seems like that information would have been a prudent addition to this great video.
Thank you.
If possible, could you please explain the gauge readings, et.al..✌️
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 ...
How about oil level ?
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?
You’re amazing thanks for helping me
WHAT IS THE APPROPRIATE LEVEL OF REFRIGERANT?
It should be weighed in to properly set the charge....It's on a sticker under the hood or refer to your owners manual
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.
