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 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)
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 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.
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
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 .
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
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
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.
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.
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.
I am also wondering if R12A can be used directly in R134A system like my 2010 Toyota 4runner?
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.

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
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
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!
This is the best DIY recharge tutorial I've found on UA-cam 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
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.
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?
Agitating can send liquid into the system won't that damage the system? What were the pressures?
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?
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.
are these instructions for a self sealing can or does it matter
Thanks for the information thanks again just want to ask for how long ikeep chasing the bottle
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 .
So what was the pressure gauge for?
What is the brand name of the can tap with pressure gauge assembly you are using?
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.
Very clear and slow step by step video. However, it did not show the gauge for the pressure.
Good job ! Thank you !
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.
Please explain the gauge that was attached to the hose.What should be the pressure reading I.e. before and after you charge?Thanks.
Finally! A guy who speaks ENGLISH!!!
thanks for hiding the gauge all the time.
Haha
Hahaha,,,,,,,,
Michael Owens yeah lol this guy is a dumbass
😂😂😂😂
🤣🤣🤣🤣
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!! ♥
Great video , May be we have to do the dye can first to seal the leak ?
is that hose just for cars? is there a adapter to use it for recharge a a/c window? thanks in advance
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.
You should of showed us the Gauge has you were charging the car , that is the main point to show !
do i need to use vacuum pump if im just topping off to a low refrigerant ac system?
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.
Thanks for for keeping us guessing by hiding the gauge…
Why the gauge is not visible during charge most important ?
what's the purpose of the big blue round thing with the two little screws? Do i need that?
Don't u have to vacuum it out first n then recharge?
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 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?
I have a 2009 Pontiac vibe GT I bought the refrigerant and the hose and I’m a little concerned this isn’t so easy. I’m somewhat handy, however I don’t want to damage my system
Wow - vastly superior to other do-it-yourself videos on UA-cam!
👏👏👏
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
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 🙎
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?
Waited & waited for gauge info. Thats the
Most important part.....
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
NICE THE WAY YOU EXPLAIN, I HAVE TAKEN H.V.A.C. FOR TWO YEARS

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....;)
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.
Does the compressor has to bw engage first?
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 😂😂😂😂😂
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.
good video but what's the appropriate gauge for the refrigerant
i just wanna know how to use it i turned on the a/c button closed the windows put the fan on and still sweating! my car is a nissan note any ideas how to use it?
Purpose of the gauge, show your readings before, during ,after.
The way you did it, just use a hose w/2-couplers!
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
Hi Are you working R-142b for Car ?
Hello. After finishing the gage keep giving me alot of pressure ehile its closed and i am scared to store it before i see zero on the gage
I'm just sitting here wondering why you need to hold your camera tripod.
semble assez bien expliqué parcontre je recommande de regarder plus que 1 video merci!
Where can you buy that part (hose+gauge assembly)? What's it called again?
The lowport on my gmc yukon is just a hole there is nothing inside of it, is it missing something?? Help helpppp
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
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.
What is the gage for if you don't watch the amount going in? You could over fill!
can I do it during winter? 5 degrees Celsius?
When he hooked up the hose if you looked at the gauge it was in the blue already I guess it was already full.
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 🤦♂️🤦♂️🤦♂️🤦♂️🤦♂️😆.....
I did it step by step thanks for this knowledgeable contribution ❤
Can we same gas (12a) in elantra 2011?
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.
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.
What is the reading of the gauge after fully refilled ? That is the key point!
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...
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
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.
Why are you using R-12 on R-134 system, and nice gauge
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!
Great vid with clear instructions. My A/C is now blowing winter! Thank you, sir.
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
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.
what about the new cans that close when you pull the plunger back out?
How about oil level ?
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
Thanks for the tip about releasing the air from the hose.that really helped
I lost the cap to where the frion goes .. will it leak out?
Kernt thee frog here... Good video.
I thought it was George McFly.
1.1 mil views and u didnt show the pressure guage at full. Why talk at the end of the video when the info is helpfull at the beginning of thd video.
can we use r134a oil in a can?
What should the pressure on the gauge read?
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
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.
Will the car be on while doing this
What is that hose called. I need one.
