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!!!

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

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.

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!!!

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.

since the beginning i was hoping and awaiting to see the meter readings....but you simply killed my dreams.

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.

This is the best DIY recharge tutorial I've found on KZfaq for beginners. Detailed and not overly hurried like others are.

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!

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.

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 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.

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!

Very clear and slow step by step video. However, it did not show the gauge for the pressure. Good job ! Thank you !

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.

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).

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.

Since he hides the guage...Quick tip....Put thermometer in Vent...when the temp is 40°-45° ur good....DO NOT OVERCHARGE

Please explain the gauge that was attached to the hose.What should be the pressure reading I.e. before and after you charge?Thanks.

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.

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~~ ☺

Thanks for the information thanks again just want to ask for how long ikeep chasing the bottle

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!

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 of showed us the Gauge has you were charging the car , that is the main point to show !

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

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?

Why the gauge is not visible during charge most important ?

What is the required level of refrigerant reading on the meter? Or is the amount different based on your car specifications?

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.

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. 👌👍🏼

thanks for hiding the gauge all the time.

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!

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! 💕❤

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.

So what was the pressure gauge for?

What is the brand name of the can tap with pressure gauge assembly you are using?

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

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!

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

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

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?

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.

You specify in your description that the refrigerant used is R134a, but you are using R12a in your video. The filling processes are different.

What is the reading of the gauge after fully refilled ? That is the key point!

is that hose just for cars? is there a adapter to use it for recharge a a/c window? thanks in advance

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!

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...

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.

When he hooked up the hose if you looked at the gauge it was in the blue already I guess it was already full.

Thanks for for keeping us guessing by hiding the gauge…

good video but what's the appropriate gauge for the refrigerant

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.

Purpose of the gauge, show your readings before, during ,after. The way you did it, just use a hose w/2-couplers!

also when you start the engine make sure the the compressors clutch engages

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, 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

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.

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 😅

I did it step by step thanks for this knowledgeable contribution ❤

Thanks for making this video! It is awesome. may I know how to buy the pipe needed for refilling gas? what is the keyword to search on Ebay. Thank you

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

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 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

great video, showing the gauge reading would have been good

Great vid with clear instructions. My A/C is now blowing winter! Thank you, sir.

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 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?

Thanks for letting us know what's the appropriate pressure level too 😮

WHAT IS THE APPROPRIATE LEVEL OF REFRIGERANT?

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

To helpful diy thanks the good tip on the ac refill you never learning thanks again my friend

Where can you buy that part (hose+gauge assembly)? What's it called again?

How about oil level ?

not a good video, why did you not show the Guage before and after?

Waited & waited for gauge info. Thats the Most important part.....

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!

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.

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.

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

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.

hey buddy what is the appropriate gauge pressure...../.you messed up bro.... numbers rule the world......take a lesson for next video

Kernt thee frog here... Good video.

what's the purpose of the big blue round thing with the two little screws? Do i need that?

Great job on the instructions!!

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

forgot to talk about pressures 30 to 38.pounds never looked at it silly

I lost the cap to where the frion goes .. will it leak out?

Does it ever take two cans? I put the whole can into the system. The van is definitely empty. The air is a little cooler. But the gauge still read low. Is the gauge broken or does this mean I need more refrigerant? Thanks for this video!

This duffs must be a Kindergarten teacher, talks as if he is talking to a child. Thanks Mr Rogers

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 ...

Why are you using R-12 on R-134 system, and nice gauge

I still have no idea how to use a guage or how much refrigerant to administer. Off to find another video, thanks.

Finally! A guy who speaks ENGLISH!!!

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....;)

what about the new cans that close when you pull the plunger back out?

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🙏👨‍👩‍👧‍👧💞
