LIFE SAVER!!!! THANK YOU SO MUCH. I was searching all over the Internet and was only seeing “take to an AC specialist” when I don’t have take-to-an-AC-specialist money! You came in so clutch and it was such an easy fix!

This is legit video DIY. Not like all other videos, after watching over 5 minutes long and the end tell us to take the car to AC specialist. This trick take less than 5 minutes and save $100 - $300 from AC specialist. THANK YOU !! BTW, you need to run the car and AC on HIGH, when you try to release the freon out. Do it slowly and and watch the gauge. So that you don't empty out too much 😁

THANK YOU!!! I seriously can’t thank you enough!! I thought I made a really stupid mistake and cost my family a fortune. Your video fixed the mistake almost immediately!! God bless you!!

Well I had exactly the same symptoms and thanks for your video I was able to fix it and it's working perfectly fine now. I can't thank you enough, you saved me a lot of money!

I saw a bunch of videos like this one and yours was the most direct and ready to understand. Keep up the good work and thanks.

Saved my life ❤️ thank you! Accidentally overfilled my AC and it was making knocking noises, turned off the car looked this up and followed your directions running perfectly now! Thank you for saving me a very expensive fix

Thank you, man!!! Tried to fix the wife's AC and I accidentally overfilled it. Now you're gonna make me look like a hero 😂😂

this was the missing piece in my puzzle. Thanks for making my cross-country trip more comfortable!!

This guy is literally a genius. Especially if you have the trigger hose. I don’t think you need that, it just makes it even easier. The air and Freon that came out wasn’t even that bad. Went from no AC in hot summer heat after I overfilled while trying to recharge back to nice, cold AIR! Thank you!!!

My man, it worked! Let out a decent amount from over charging and the more I let out the longer the compressor spun. I continued to relief pressure until the compressor spun consistently for at least 5 mins, then took it around the block. Got back home still engaged and air is much cooler. Thank you so much for this video!

THANK YOU! I used a cheap recharge can without a gauge and over filled my AC, this video was EXACTLY what I needed to get it fixed.

Thanks mate, I literally was just pulling my hair out over my sons 2001 XTerra, ac compressor turning on and off, hooked up my gauge and it was pegged into the red! Bled it down, compressor stays on now! It's Vegas and 117 this weekend, likely expanded gasses for sure! THANK YOU!

"I'm not a pro, found the gauge in my pile of junk" ahahaha! 😂

Wow man, thank you for the quick to the point video that saved me from burning up in 100+ weather. I can’t thank you enough

Wow. I have been struggling with this all summer. I thought it was the condenser was bad. Maybe the plug was broken. Nope it had too much air. It was overfilled. I took the gauge that had the trigger, held it down till it went from red down to low (it was warm air and freon) replaced with a can of ez chill ....bam! Done. I'm literally writing myself directions in case I have to do this again in the future. This is literally the only video on KZfaq that suggests letting some of the air out. I didn't even think about that. Thank you for taking the time to make this video. It saved me money at the repair shop and probably heat stroke..

You, sir, are a 💎 Diamond! Thank you so VERY much for this help. It not only saved me a trip to the mechanic but was able to save the perfect amount of refrigerant without losing everything. My dilemma was adding a little too much. I am also dealing with an intermittent climate door actuator that I was hoping wasn't it today. Crazy heat this week, windows will not roll down, fixing everything as I go.... this weekend they will be next (I usually do my own work if I can) Thanks to great people like you!! 🎉

Super easy and my Freon is back in the green zone. Thanks for posting this.

Thank you so much for this information. I followed exactly what you did and I was able to bring the pressure down to exactly where it needed to be. My system was overcharged and I was noticing the A/C Compressor kept engaging and disengaging. Thank you again.

You saved me bro! I have charged the system successfully in the past, but this time gave it a little too much juice. Was able to get it proper again with your help. I had also replaced the serpentine belt and tensioner as they had been loose/ squeaking and impacting performance. It’s like a new system now!

Its 25 June 2020, 9pm central California time... I was about to body slam my car... Thank you, my car is better because of you.. ❤

Wow thanks man !!! Car was doing same as yours plus mine was blowing heat instead of cold air now it's working 100%

Thanks man. It literally took 5 minutes to fix my wife Stacy after watching your video on her 2006 Jeep Liberty the pressure was fluctuating around 30lbs. Now it's steady at 50lb after relieving the pressure.

Short, simple, and quick to the point. This helped out a lot! Thanks 🙏

This really saved me a LOT. Worked perfectly. I used a plastic bag and just threw the end that would be expelling the gas to keep it more contained instead of possibly getting in my eyes!

Bro. You just saved me lots of $ and worry. I overcharged my AC and the symptoms are exactly like you described. Now my car is all good. Gosh, thanks heaps man. You have a good new year !!!!

If it's a bottle Gage and the bottle is empty you can slowly unscre the bottle and while wearing gloves and the bottom where the bottle goes pointing it away from you with the engine/compressor running, let some of the gas off. Don't let too much out at a time. When you hear your compressor kick back on the Gage will indicate the pressure in the system.

It static pressure video was a life saver. Since I didn't need to buy the high pressure and low pressure gauges . Thanks dude. Straight up to the point explanation.

Thanks for the video! This is probably the worst thing I could have done to fix my overcharging problem, but it definitely saved me time and $. Wore a gas mask & nitrile gloves. Sprayed into a ziplock bag, covered with a shop towel, because this stuff leaks too.

I did exactly wat you said an now my ac is working like it was Befor i over charge it.Thanks for sharing your knowledge!!!

Wow. thank you so much I must have used an old can which refilled the levep but then it must have gotten air in there. So once I drained it untill it stop fluctuating bam AC is ice cold. Thank you so much you saved me hundreds of dollars.

Omg!!!!!! This is the trick of the decade! Im in Vegas in the middle of the summer, this trick is priceless!!!

I did fix my A/C yesterday, And works much colder than I bought 8 years ago. I never had adequate cold flow to a satisfactory level before. Dumb me not going on KZfaq and fix it in 5 minutes. It stopped blowing cold air since last year. I thought maybe the car getting older and that’s what I get! I was wrong . All I had to do was to hook up the pressure gauge. The low showed too high on the red. I released pressure down to blue line and started working again like it’s new. Buying the pressure gauge was all I needed 👌

You are the man!!!!!!! Straight life saver. I thought I had to spend a butt load of money to fix my issue, but you saved the day..........a million thanks bro

Your are THE MAN! THANK YOU FOR THE INFORMATION! I used stp a/c pro can on a maxima I could hear the compressors shut off and on after I filled it. It's a 20 oz can the unit calls for 5.2 oz of freon I had overfill even tho the gauge wasn't marked in the red was in the 50 psi range I took your advice and bleed the system under 40 and it's back to normal and air is blowing so cold now btw I live in Las Vegas!! THANK YOU SIR YOU ARE A LIFESAVER!!!!!!!

This information is worth its weight in GOLD! Did exactly as you instructed and it worked like a charm. Thank you so much for sharing this. Liked & subscribed

I found that exact same hose for $15 bucks. Worked instantly! You just saved me $200 and a summer of riding in sweltering heat. I am icy cold once again. Thank you!

Worked really well!! Note to anyone trying this, you might have to do it multiple times after driving bc the pressure can go back up so don’t expect the first time to be perfect

Thanks my man! I just charged my car yesterday, and the pressure and AC were fine. Today it's extra hot, and AC was blowing warm air. First thought was to add more refrigerant, but gauge almost pegged, so I knew I had to relieve the pressure instead, but didn't know how. Your video showed exactly what to do, and the tip about using a hose with a trigger on it was super great! Now my AC is cold again, and it didn't cost me a dime to fix the problem! This is what KZfaq is all about! Great job!

Sir thank you I just did this to my car after overfilling it. One day before the kid goes back to school you sir saved me a very hot time. My family thanks you!!!!

Thanks a bunch bro! It worked and now I'm enjoying some nice cold air.

Having this issue right now. Debating on whether not I want to attempt bleeding off pressure or just taking it to a shop. I normally work on vehicles myself, but this is a little above my "pay grade". I haven't ever worked on pressurized systems before....

Accidentally overcharged my ac n this video help me alot thanks

Thanks for the video. My AC was working in the morning and late evening but right at 3PM when it's super hot the AC was just blowing hot air just like your issue. I could hear the compressor kick in and out so I know there's Freon in the system and system is working. I release some pressure out a few times and now my AC is cold once again. Previous owner probably did some work on the system and either overcharge it or not enough Freon. Thanks!

Thanks man.. good info!! Taking car in for warranty work and had overfilled Freon.. easy denial for them. Worked perfect 👍👍

You saved my life with this video! I can’t thank you enough! I just swapped out my compressor today. I filled it too much and went into panic mode because it was blowing hot air. I came across your video and followed your steps, now I can see my breath when my AC is on 😂 thank you thank you thank you!!

that's very cool. I'm always afraid to work with stuff like this. awesome video

I was so scared because I thought I ruined my daughters car. I overfilled the freon and started hearing the clicking noise. Used your steps and now it's working like new.👍🏾👍🏾👍🏾👍🏾👍🏾👍🏾

Thanks I was a tiny bit over. Your vidoe helped. When you get close to 45 psi it doesn't take much for it to shoot up past that.

Thanks for the tip ! I overcharged mine and this worked perfectly

Thanks for the video man! Just put too much refrigerant in my car and it was blowing hot. Quick KZfaq search and found your video. Much appreciated! ✌🏼✌🏼❤️❤️

Omg thank you. I know this is exactly whats wrong with my truck. Can't wait to fix it tomorrow

Worked like a charm for me. Thanks for making this video.

Thank you so much . I thought I just blew my compressor after misjudged recharge . I removed some refrigerant and now the ac is back on track . 😊

Thank you, sir! You saved me from buying a new compressor.

That gauge came off the Interdynamics EZ Chill R-134a Refrigerant sold at many auto parts stores. About $25 to 35. Works like a champ.

Hey thanks for the help I released some of the gas and I have air-conditioning thank YOU SOOOOOO MUCH FOR YOUR HELP

Thank you so much dude! You saved my 2017 Nissan Frontier’s AC’s life! I thought I completely fucked my air conditioner because I over filled it but thanks to you I let some pressure out and it works like new again! You saved my ass bro thanks again!

You just saved a trip to mechanic!! Thanks Man.

OMG, YES HELPFUL AND IN MY SIMPLE ALTHOUGH VERY EDUCATED MIND I UNDERSTOOD WHAT AND WHY YOU WERE DOING WHAT YOU DID! OMG, 5 Stars for your HELP!

Thank you for this video. I have managed to sort out my problem with the ac compressor. I hope I didn't break it on medium and long term.

Thanks this video helped out. In my case, I had too much Freon and had to release the pressure. It sure sounds like either you have too much pressure or too little pressure and the compressor therefore turn on and off. If you just recharged it I would imagine that your pressure is too high. And if you haven't recharged it, it probably means your freon is running low. At least that's my opinion.

Ugh worked perfectly. Thank you!!!

I plugged the gauge in and reading was high. So I thought I cant recharge unless I like empty it. Turns out I needed compressor to be on. Do it again, and its low. Job done in 5 minutes. Thanks for the video.

Thank you. 2004 sienna had too low such that compressor would not kick on so I jumped the wires to get it going. Slowely filled, for about 2 minutes it blew cold but I think it overfilled (now that I see your video) so I'll need to back it out a bit. Havent done it yet. Will tackle tomorrow.

Thank you. Worked like a charm. My car A/C reacted exactly like yours did. Pressure was too high and compressor wouldn't run for more than a second. Let some R134 out and it started to run, then the pressure built back up and it stopped, so I let some out until it runs as it should.

Thank you so much. I was really worried and thought about the money and trouble taking it back to my mechanic but I followed it exactly and the excess pressure was removed and ac is back cold again!!!!

Thank you.... saved over $500 repair for something so simple.... just have to always tell myself, "KISS it"

Bruh you’re more helpful than any mechanic I have been earned a sub

I haven't read all the comments but, I made the mistake of not watching the AC compressor while it was running .....I had the pressure of the low side spiking when the compressor cycled OFF. Professional hvac advice I received was that at 90 degrees the low side pressure could be in and around 55psi. Note that while compressor was running pressure was 39 psi which is near optimal. Watch the gauge reading in relation to compressor on/off state before adding or removing. The pressure of your on cycle should be what to focus on.

Could be a faulty high pressure switch...

Thanks!! Simple and fast. Got car going after 2 minutes

Awesome vid.... I filled my car ac and I put way too much. AC didn’t even kick on because there was too much refrigerant. I used the artic freeze trigger and just triggered away the excess gas and now it’s working fine. My trigger gauge colors are different where green is good and white is low. Thanks

Thank you very much. Just had this problem and thought the worst. Was a pretty quick fix overall. You are doing great work

Ken Graham If overcharged put charge can in ice water wait a couple minutes for it to cool, stop engine to increase pressure, open valve coolant, gauge should drop as high pressure migrates to cool low pressure but will start raising again. Shut gauge quickly give time for ice water to cool new hot gas in can, repeat. Start car check pressure if still to high repeat, if too low remove from ice water let warm up and while running add a bit, wait and let that cold refrigerant equalize as comes up to temp of motor refrigerant. This worked for me on a R410a 1 ton air conditioner, I see no reason it won't work for you with a empty or near empty can. This would legally fix your issue as you are not releasing it to environment, and you have refrigerant for future use for that vehicle. If this works for you as well please up-vote to move it up list.

Reducing pressure worked for me too. Initially, I didn't trust my gauge showing high pressure, because every time over the years I've had my A/C compressor not engaging or cycling off unwantedly, it's been due to low pressure. I now know the gauge was correct that my refrigerant pressure was high. My first inkling of this occurred when turning on the A/C the next morning caused a grinding sound. I only kept it on for a few seconds, but I was still concerned I'd burnt out my A/C compressor (luckily not, though I may have still done some slight damage). When I removed the port cap, I noticed it didn't just make a small 'pfft' sound, it blew the cap somewhat forcefully into my hand. The same sort of over-pressurized clues continued afterward as I connected and disconnected the pressure gauge (that you use when adding refrigerant). One observation is that, for my A/C system, the pressure did tend to drop over time, say over 15 minutes, while idling. Yet I wonder, right as I first got in my car and carefreely turned my A/C on that morning, if being in heat wave weather combined with sitting in the sun hadn't raiseed the pressure, causing it to reach even higher pressures than the previous night when I'd added a can of refrigerant, resulting in such a high pressure that some refrigerant wasn't fully evaporated (i.e., still a liquid) before entering my A/C (gas) compressor. I've read that you get the most efficient cooling in the middle of the recommended range (assuming you can trust your gauge) because that's the pressure range it was designed for. I'm no expert, but I'm thinking that the pressure, even when the A/C system is functioning correctly, will not always operate at the exact same value, depending on outside factors like ambient temp. and how long the compressor has been continuously engaged (and maybe whether at high rpms or idling?). So it's that range of operation that you want to keep within the 'recommended/normal' range on your gauge.

You're a good man! I followed your trick and it worked.

Thank you so much my friend you were dead on and save me lots of money from replacing things that work, at night it says on and works perfect and during daytime heat it cuts in and out so I bleed the line and watched the gauge leave from red to blue and ac stayed on and now works all the time; great hypothesis sir

"If it get in your eye... you go blind."- EPIC warning

squeezed out a pinch of freon till compressor kicked on, ICE COLD again, thank you!!!

I have this problem right now, thank you sir for your video tomorrow I will be doing mine

Mannn thanks you saved me a lot of cash you the best !!! :)

You’ve saved another one, I had the exact same problem, thought I under-filled according to the gauge but it looks like I just overfilled. Much love man.

it worked for my Silverado 2011 that was constantly running high for the cooling fans, high noise when they are at high speed constantly, and I read is a symptom for overcharged, and this fan high speed happened after last gas fill I did. due to leaks fixed with 3X sealant can. Thank you very much.

Thank you! Have the same problem. Going to see if I can recharge an old can as I release the pressure. Somebody else pointed out the pressure reading drops when the compressor is running and that’s the reading to use. I’ll look the that difference as well.

Thank you sir. This will always keep me employed 😁

thanks for the help! Mine was saying it was at 55psi, revved the engine and then it suddenly was off the charts. Let out pressure back down to 50 viola, back to 75f instead of 100+.

Thanks, man stupid me over pressurized the A/C as well. Worked fine last night and this morning nice cold air. Driving home from work today at 5 90 something degree weather and was sweating balls. Released some of that pressure and thank God!

I have the exact same gauge and mine showed in the yellow , I backed it off until it was in upper blue and air is colder. Thanks for your video

Thank you! Problem solved.

It’s supposed to be high when the compressor isn’t running. When the clutch kicks in and the pressure falls, that’s when it should be measured.

My Chevy Cruze did this I had to let pressure out 3 times because it gain pressure on its own I thought I was going insane thank you for explaining why this happens

this video saved me so much money. I added too much freon and it was blowing hot air. Went back and released some pressure and now it's cold as ice. For a moment I thought I needed a new a/c compressor.

I used a/c pro to recharge my system in my 2009 Lincoln MKS. I did it once a few years ago and it was perfect. Cold air, no issues. The AC started to blow warm again in June 2022, so I figured I'd recharge it again. This time, not so good. While charging, I noticed my engine stuttered and the a/c pro gauge jumped back and forth. When I got into the car, the air was warmer than before. Thinking it just might need some time to recycle, I drove home. The AC never got cool, the engine was rough, and the RPM gauge in my car jumped wildly. I ran the ac when I got home for about 25 minutes, and nothing changed. Now I think I have an issue and will need to go to the dealer (likely $200-$300 to check, evacuate, and recharge). Before I made that call, I thought I'd check once again on how I might fix this, and saw this video. I watched it a few times thinking it couldn't be this easy. I read a hundred or so comments. Many thanks and good results, so I thought I'd try before making the dealer appointment. I put on my gloves, grabbed a towel, and before I turned the car on, I attached the A/C Pro gauge without a can and pulled the trigger. IT WORKED! It only took a few short squeezes. I started the car, turned the AC to full blast, AND IT WAS COOL!. I went back to the gauge to check the reading while the AC and Car were on, and made a few more short squeezes until the gauge got into the green and settled in the green at 25. Removed the cord/unplugged, recapped the low-pressure input, closed the hood, and enjoyed cool air inside the car for 25 minutes. I turned the car off, waited a few minutes, restarted, and turned on the AC. It still worked. The whole thing took under 10 minutes. I'm so happy. Saved me $200-$300, and a day at the repair shop. I know you're not supposed to release the contents of the system into the air, but it was so little I don't feel bad at all. Thank you @Yourself for this most helpful video.

Does your radiator fan /ac cooling fan spin in high speed mood before?

glad i came across this video i dont know exactly what the problem is with my ac but 3 years ago had the condensor replaced due to a leak and for the 3 years it was just fine and then one day it was just hot and was the first time of the year using it so i figured ok lets buy a refill and went to hook the gauge up and the psi was up to 101 and then i let pressure out until it was in the middle of the green and now its ice cold again hopefully it was as simple as that but still going to take it in and see what they say

Fixed my problem! Thank You!

Two words; thank you

Awesome video, wish I watched the whole thing cus now I'm blind. But I saved some money #worth

I tried it and so far it seems to have fixed my issue. Thank you!!!
