A/C Leak Testing That Will Guarantee You Find It!

2016 Subaru WRX. In this video you’ll see how to utilize the ATS Leak Detector to find leaks in an AC system. You’ll also see how it can be used for evap leaks as well. This tool has really helped us to keep vehicles from leaving with dye in the system and telling them to come back later. It’s perfect to help you track down the small leaks! Hope you enjoy!

I am an hvac tech and I just want to let everyone know that its not a good idea to use shop air or any other type of contaminating propellant because you could introduce excessive moisture into the refrigerant loop and moisture with refrigerant and refrigerant oil entrapped in the system could cause clogs or rapid corrosion which will eventually require a full system replacement. When in doubt pick up a tank of dry nitrogen gas. Its clean and moisture free. The only issue would be that you would have to first add a small amount of refrigerant to use as a trace gas for a refrigerant leak detector. This would only be needed mainly to test the evaporator side that is difficult to reach, otherwise just nitrogen pressure and soap bubbles. NEVER use oxygen to leak test or come in contact with a petroleum based product as it could react violently and combust.

[@Taillighttim26]

HVAC know that you are 💯 right most shops use the dye to pinpoint leaks putting anything else in to it you will definitely shorten the lifespan

[@bigo975]

U are correct!

[@pedroclaro143]

But If you have a leak and have no gás on it, shouldnt the system be filled with normal air that hás already moisture in it?

[@AshLongie]

When there's a leak will It have moisture in system anyway from the hole in system ?

[@JohnH1370]

DRY NITROGEN ONLY WITH TRACE OF REFRIGERATE

[@raymundomiranda7853]

Yes, please do an evap system

[@theroyaltyautoservice]

You got it!

[@JoesAutoElectric]

Great video, Sherwood. really important to use the equipment properly when chasing these leaks. I used to work with a guy who would use the electronic leak detector with a huge fan blowing on him, then complain that the tool doesn't work. I never got to use the bullseye kit, but it looks to work great! I'd love to se more videos using it.

[@MrSubaru1387]

Those Valeo compressors definitely fail at a higher rate than the Denso compressors on Subaru.

[@8power0]

DEFINITELY NEEDING MORE OF YOUR SUPER VIDEOS PLEASE,, BECAUSE WE ALL WHERE WAITING PATIENTLY AND IT FELT LIKE AN ETERNITY ,,,,,,,, ITS JUST HOW GOOD YOU'RE VIDEOS ARE . SO PLEASE SEE WHAT YOU CAN DO WITH UPPING THE ANTI ON THE VIDEOS . THANKS SO MUCH FOR THE TIME AND EFFORT THAT YOU PUT IN TO THESE GREAT VIDS🙏🙏🙏🙏👍👍👍👍

[@alexlongpre4527]

Please do use it on an EVAP. I'm trying, at this very moment, to sell this kit to my boss. Your straight to the point videos might just be the ticket to make him swallow the pill.

[@greg7886]

4k plus the cost of a tank. Jeez I know it's a great kit but there is some huge margins in the ATS stuff.

[@alexlongpre4527]

@@greg7886 It sure is. It is certainly not made for a small shop, even less for the DIYer, but if you do this kind of work day in, day out, with the time you save it'll pay for itself in no time. And I'm not even factoring in the fact that with R1234yf, every time you unhook the machine, you loose about 35$ worth of gas... You can also make do with the less expensive kit that does not include the device that automatically shuts the EVAP valves.

[@isalmankhan1]

Superb👍 Definitely want to see an EVAP leak test video😍 Thanks for sharing Professor, Stay Safe👍

[@mobileair6416]

Nitrogen at 300psi and Big Blue. Easy find and this is a common leak at the seal, especially if it wasn't used for a period of time.

[@Discretesignals]

Agree. Paying $4500 for the bulleye leak detection tool is crazy, in my opinion, when you can do it with nitrogen tracer gas and Big Blue and/or ultra sonic leak detector.

[@luismarty1685]

Wow, you guys have the top of the line tools.

[@williammargrave4891]

Thank you for taking the time to present this to us. It is so nice to see there are intelligent techs still out there. I would LOVE to you use it on an evap system. thank you I will buy one of those this week.

[@kevinminor2558]

I have this tool. It worked for 3 mts and Leak detector broke. Its under warranty waiting for a new one. It's a good tool. Hope the next one last's longer

[@garysmith9772]

More often than that, there is more than one leak. That’s where most people get into trouble as they stop looking when they find one leak they go to the trouble evacuation recharge, and then the customers back with the same complaint. Pressure test with nitrogen or CO2 for at least 2 to 3 hours and see if you’re continue to lose pressure.

[@dag221]

I was very curious what the process was to repairing the leak around the bolt.

[@LRBennettInc]

I'm sorry if I missed it but what PSI are you charging the system to? And why can't you use nitrogen?

[@alaingillot4718]

Dry compressed air and soapy water also work well , bubbles dont lie . Also dye

[@amigo2k10]

Yes i want to see an evap system check

[@justinsherwood1911]

Cool video and I like the detailed explanations you give. When it comes to AC leaks we use Nitrogen with Hydrogen trace gas and a Hydrogen detector. It's good for evaps as you can usually pick up at the vents due to the Hydrogen rising.

[@advancedleveldiagnostics]

Thanks for the demo! Is C02 Safe for AC systems, I thought it had high moisture?

[@crasher88]

defiantly wanting to see this kit used on an evap system.

[@lesliedaisley7846]

Would love to see this leak detection tool on an evap

[@miguelle9724]

How do you feel about using AC dye & UV light to diagnose Freon leaks vs CO2 leak check?

[@theroyaltyautoservice]

I have no problem with using ac dye. It can take longer to find if you have to put it in then wait for it to leak and show a leak. This method allows us to find the leak right away.

[@EVO8BOOS28]

Great vid! but $5k for a kit too much for some of us!

[@davidjackson4112]

I really enjoy watching your channel Sherwood.

[@dannyspon]

Really like you videos. I learn so much from you. Thanks!

[@ripptydevibes2581]

Awesome video! Do you guys plan on every doing any tips and tricks on service writing?

[@coldfinger459sub0]

CO2 is nice it has its advantages and disadvantages as you mentioned in the video. What is your breathing if you have a very good sensitive CO2 leak detector like my Inforcon Stratuts. Just breathing in the vicinity will set it off every time. As cars drive in and out of the shop, what is a big portion of exhaust gas from an engine CO2?. When you go into an passenger compartment just yourself breathing inside the passenger compartment will rapidly raise the CO2 concentration to a couple thousand parts per million. We found it best to wear a heavy filtered mask like for the flu for Covid to stop your breath from projecting straight forward in a stream of high concentration . It still comes out, but at least it’s kind of stays around in your face area.. Hey nitrogen, helium or nitrogen hydrogen with a dedicated leak detector for hydrogen or helium. Works much better and you never have to worry about CO2 contamination from your breath or vehicles being started or driven in and out of the shop while you’re trying to perform your test..

[@knock904]

Would this work with nitrogen..workin on old R12 system..Got a extremely small leak .Really kick my but ..Thanks n advance

Forming gas is a mixture of hydrogen and nitrogen, typically in a ratio of five to 95 percent, personal preference

[@JohnH1370]

Dry nitrogen only with trace of refrigerate

[@SeriouslyAwesome]

What am I missing here? Shop air and soapy water is free. Sniffers have been around forever. I see zero advantages of expensive CO2 that causes calibration issues and goes off with every breath within arms distance.

[@crusiethmaximuss]

Magnificent advice and presentation. I know an "experienced" technician and he never mentioned something like these tools to a noice like me. I worked for him for free in exchange for experience for three months and he took months to issolate network problems which I have solved on campus in the same day... I guess he's a scumbag and not as experienced has he claims to be...

[@zahidhussain980]

It is a very bad idea to use co2. You may not know that co2 mostly has a lot of moisture in it, which will mess up the compressor and evaporator.

[@marcovargas9115]

Shop air and soapy water. Way faster

[@mastmec]

And you introduced a lot of moisture into the system, now you have two problems.

[@hid3nax]

All those expensive and bullshitish leak detection systems and sprays are not very useful for the user after he has purchased them. It's just waste of money for you as a customer and you increase income for the companies which make/sell this stuff. Simple thing: pump up the system with pressure, several atmospheres. You can use CO2 tank for that. Observe gauge to see if pressure drops rapidly. If it does then you have major leak, shouldn't be difficult to find. If it doesn't drop rapidly, use tyre spray / leak detection fluid and spray common leak areas: firsly all the joints for possible leaks out of o-rings and lose fittings, compressor and its area, entire radiator (especially its lower end there it gets sand and stone blased), dryier. You WILL find a leak. No need to thank me.

That is too expensive... just use shop air and soap+water...

[@garylee8132]

You're over complicating it all you need is a smoke generator for evap and vacuum leaks, and nothing but a black light UV flashlight for HVAC. Plus these two items are not near as expensive. And if you're testing an ac system just nitrogen and a set of gauges and a micro-gauge.
