Ultrasonic leak detectors work great on refrigerant leaks as you've demonstrated. I've also had great success in other industries such as the automotive field in detecting vacuum, pressure and water leaks along with detecting early failures of bearings. A great tool to have! :)

[@acservicetechchannel]

Thank you very much Stuzman, thanks for mentioning the other fields!

[@exclusive_148]

thank you for introducing me to this tool. Its a game changer! I dont even know what to say. I literally dont worry about leaks anymore this tool is awesome!! Today i literally found an evap leak in like 2mins no exaggeration.

[@bbergen2399]

I use this leak detector and it is amazing! Never fails me!

[@michaelglasser6923]

Been using this exact tool for years. It’s my preferred leak check tool. I can’t tell you how many times I thought I found a leak, but it was just my arm rubbing against my leg, or my foot moving, or a spiderweb, lol. I don’t trust leak detectors in general, very fluky. goes off once, not again. Or goes off for no reason. These I know won’t give a false positive. Absolutely love these, good vid.

[@acservicetechchannel]

Absolutely, they are great, thanks!

[@NMranchhand]

I'm learning HVAC from you and now you've even improved my SCUBA equipment repair! Thanks.

[@acservicetechchannel]

Ha ha nice, I can't wait to out out soon. Flounder season just opened and we scuba spearfish. Been pretty busy work wise but soon!

[@lucdumouchel9]

I saw one of your video about 6 months ago on this tool. I was already convince it was the best. I boutgh one and It works so good. Thank's for the tip. Really appreciate

[@acservicetechchannel]

Thanks a lot Luc, I am glad you like it!

[@danpmatz]

How small of weeks can you detect for example do you think that you can hear something that only leaks about 1 pound a year. I've got the Fieldpiece meter now and I feel like the thing is a joke. The only thing I'd have success with his isolation test I just looking for something quicker

[@zipperdingo6385]

Craig you are accurate and sharp in every detail you provide, thank you ever so much

[@acservicetechchannel]

I appreciate that!

[@2020romania]

I was working on a large dehydrator for pneumatic process controls at a paper mill. I was having difficulty finding a leak because of the noise and a lot of air exchange /air movement in the area. Customer had a ultrasonic detector and let me try to find it with that. I found it almost instantly. Great tool👍👍

[@acservicetechchannel]

Yeah that is a common misconception, thanks a lot Kevin!

[@MrChipBryant]

Purchased one of these, changed my life. It'll pay for itself in 2 or 3 calls.

[@Riomadness]

Ba ba ba bad. Love it. Great video. You are always right to the point, no fluff.

[@acservicetechchannel]

Thanks a lot Leslie!

[@throttlebottle5906]

seems to be a great tool and concept, in addition to old school detectors. I could see finding the general area of leak with other methods and pinpointing with this!

[@acservicetechchannel]

Absolutely, thanks Throttle Bottle!

[@takleung7130]

It seems that the psi has to be relatively high for the detector to work. Will it work for detecting leaks in residential gas piping? Just wondering. Btw your vids are among some of the very best on you tube. Thank you.

[@acservicetechchannel]

It is not about the psi as much as the noise but in a gas line you may still need to wet the outside since there isn't oil on the inside of the tubing like refrigerant lines which makes the sound louder, thanks a lot Tak!

Thanks a lot ejohnfall!

[@jeffkreft9872]

I’m sold the minute you said I could use any compressed gas (nitrogen) to find the leak, I mean let’s face it, when checking for leaks in general usually done when the system is low or out of refrigerant pressure, no more wasting refrigerant to find the leak. Going to buy one of these right now. Thanks for the video, never befor considered getting one of these till now.

[@acservicetechchannel]

Thanks for your note Jeff!

Do you think it's a good idea to use DEWALT DCE200M2K 20V Plumbing Pipe Press Tool Kit with Crimping Heads for HVAC instead of soldering or brazing can you do a video on

[@acservicetechchannel]

We haven't heard anything about any joints leaking bad yet when the crimp is properly done. I think each tool has its place for different circumstances, but I don't think I would be doing that on every joint, thanks William!

[@FireandFrostHVAC]

Agree completely. Good video, thanks. I’m going to buy one in 2019. Merry Christmas AC Service Tech! 🎄

Would the ultrasonic leak detector detect leaks under vaccuum?

[@mitchs6764]

How well do you (or anyone else reading this) find the tool to work in noisy environments? I have always dismissed this method in the past because I was told they suffered unless there was little to no ambient noise. And haven’t met anyone who uses them in my area that can give me first hand knowledge. Thanks for the videos. A huge help!!

[@acservicetechchannel]

It can work well in noisy environments depending on the noise levels. I have been in very noisy and windy locations and the tool worked well. I was on a rooftop where it was picking up noise from a transformer half a block away when I pointed the tip in that direction. It really depends on the types of noises you are around. It really works well in wind. Overall, I am exceptionally happy with this tool and its ability to find leaks, thanks!

[@tomz4110]

Thank you for your vid

[@mike-yp1uk]

I would love to see ultrasonic leak detector war. Compare different types

[@damnitdang]

Is the tip sensitive to grime? Can it be cleaned .

[@danielwarfield1027]

I'm in a pinch and I need to buy an ultrasonic detector for a large multizone system I installed, but it won't hold pressure and Big Blu failed to show anything. Do you know any techs using the Inficon Whisper? Do you think I can get by with the cheaper Inficon model?

[@notanewbie1718]

Got a link for this one?

[@acservicetechchannel]

Here is a link, thanks- amzn.to/2Lw4Zpr

[@chrisdiaz1830]

My local johnstone only offered the Inficon Whisper 711-202-G1. Do you have any experience testing that one out?

[@acservicetechchannel]

I did not have a great experience with my last inficon. It wasn't finding leaks. However, I love my ultrasonic tester and I rely upon that for testing for leaks. I have the tools I use linked at amazon.com/shop/acservicetech thanks!

[@bigbad209mm2]

Im trying to find a leak that is likly a zoomlock fitting between floors on a occupied apartment i isolated the system and narrowed it down to the liqud line. The lineset is 70' r more running over 3 apartments will ultrasonic leak detector pick jp leak through sheetrock?

[@acservicetechchannel]

That may deaden the noise. You may have to drill a 3/8 hole into the wall cavity like through the trim to put the yellow extension tube through and then you can add sealant afterward.

[@bigbad209mm2]

Yea i already cut 4 holes in cieling but havent had any luck .we use amprobe ultrasonic ears which seems to pick up the noise every time you touch the ladder or sheetrock or scratch your arm so I was curious have anybody ever successfully found the leak through sheetrock thank you for your reply

[@lesliedaisley7846]

Bro do you have a link for a discount on this ultra sonic leak detector and does this find very fine leaks

[@mikefreedom5612]

Thank you

[@swinginmad]

suffering sticker shock. nice video. TY

[@acservicetechchannel]

Thanks!

[@juanjreyes1]

Thanks for the info, great video. Do you know of the ultrasonic leak detector can locate leaks while the system is in a vacuum. Thanks!

[@acservicetechchannel]

Juan, movement through a tube should be able to be picked up but I couldn't tell you based on experience because I am only testing with positive pressure, thanks!

[@publicmail2]

But you have to be right on the leak vs a diode will detect the general area thru AC vent in car etc.

[@acservicetechchannel]

Its true if an area is saturated with refrigerant mixed with the air the heated diode will go off. Every tool has their function and benefits. This tool will still pick up noise a bit away depending on the noise level, thanks A D!

What is rhe differwnce between the one for 463 and the one for $610 the gooseneck?

[@turboflush]

Very well demonstrated. I only used sniffers as a last resort because of it's difficulty. Bubble soap works great also. I will look into this ultra device though. Will make work easier and quicker.

[@acservicetechchannel]

Yeah the bubble leak detector is good for open joints but when you have covered all of them and found nothing, thats when the problem arises so I am glad I have this, thanks Turbo Flush!

[@johnretired8213]

Will it show leak in my Freon pipe if there no Freon left?

Does this work through armaflex? For example let’s say a ductless system with several heads ?

Hi, what do you think of Bacharach TruePointe series ultrasonic ? I am abut to invest on one and I will love to have you opinion on which one is better. Thank you for your time and thank you for all the information you help us with.

[@zesty2023]

Quick question Craig, I've got one of these detectors mostly because of you. I was searching for a leak today and more than half way to 100% sure I found it, but I had some doubts still. I was hoping you could let me know if they were warranted doubts or not: The leak I was hearing was at the base corner of the A coil, right at the bottom leg of the A that is where the TXV lines are going in. The thing that threw me off is that I heard basically the same sound from the base on the other side of the A coil too. It made me wonder if I was just hearing sounds of refrigerant settling inside the tubes.. because I know you can hear the sound of refrigerant flowing through the tubes with this thing. The AC was off of course, everything was off. But I was wondering, since it was at the base of the A coil maybe it was like.. the sound of liquid refrigerant bubbling or something inside? That or was it just so sensitive that it was picking up a leak somewhere out of sight and I wasn't even pointing it at the area the actual leak was? Just wondering is all, do I need to worry about hearing refrigerant sounds INSIDE the pipes and mistaking them for the hiss of a leak? Since I know you have tons of experience with these detectors, getting an answer will really give me more confidence using this thing.

[@neppy5]

what are the limitations of this tool? could it reasonably detect a leak in a lineset with the insulation still on the tubes?

[@lifesajoke26]

Love all your videos I feel like I've learned so much from you. Wondering if you can do a comparison of heated diode vs ultrasonic leak detectors

[@SovereignTroll]

Also this method requires NO trace gas along with immune to wind, no delay, and useful for other fluids. Do natural gas low-pressure leaks have a Mach component that is detectible?

[@acservicetechchannel]

Low pressure gas can be detected using this tool. There also are sniffing tools designed specifically to sense the gas chemicals, thanks!

[@SovereignTroll]

@@acservicetechchannel I don't understand the religion surrounding the hot wire, semi-conductor except under concrete slabs and streets for natural gas. Ultrasonic requires no refrigerant and immune to noise and wind. I really don't like the delay with hot wire.

[@acservicetechchannel]

@@SovereignTroll The heated diode just happens to be the most well known and has the most tools out in circulation. Ultrasonic will catch on. It just takes time, thanks!

[@MrNebRebew]

Craig, do you recommend the noise canceling headphones as an option for this device? Have you been using the base model with the regular headphones, or have you been using the model with the noise canceling headphones?

[@MrNebRebew]

I’m trying to decide which version to buy. Thank you for your great videos.

[@acservicetechchannel]

You don't need anything too special. Sometimes I will plug the jack into a speaker even. Whatever you use, just get used to the noises you should do well, thanks!

[@garrythompson4132]

Rookie here, will detectors sense both low and high sides leaks?

[@acservicetechchannel]

Yes, it listens for the escaping gas coming through the tube with the oil on it even at the low side pressure or when the system is off, thanks!

[@OneBiteWillis]

Reason #11 is that i can be used on a system that has either a positive or negative pressure.

[@acservicetechchannel]

True, thanks!

VERY simple device for $500+. Virtually zero reviews for any of their models on Amazon. I've found others for about $200 which I'm sure perform identically.

[@acservicetechchannel]

Look up the comments in all the ultrasonic videos, there are a lot of techs that have these and love them! Not all tools are created equal in regard to leak testing. Let me know how the other tools such as the amprobe work if you happen to purchase them, thanks!

[@EMMANUELYESUNKOAA-bt4pn]

Where are you located

[@exclusive_148]

I never liked the heated diode. The refrigerant escapes to different areas and the diode picks up refrigerant in areas where the leak is NOT. It makes it a little deceptive. I want to Master The ultrasonic. Maybe you can use the heated diode at the start of a leak detection so you know if the leak is in the evap or condenser then once you pick up refrigerant you switch to the ultrasonic to pinpoint

[@EMMANUELYESUNKOAA-bt4pn]

How much is it

[@EMMANUELYESUNKOAA-bt4pn]

How much it

[@danpmatz]

Do you think this is the best way to find a small leak in a system?

[@acservicetechchannel]

I have found many very small leaks with this detector and rely on it on each job, thanks

[@sprockkets]

All I can say is, dont' buy the Inifcon brand of this type of leak detector. It worked but only for large leaks, while my H10PM was able to find more.

[@acservicetechchannel]

Yeah I had an inficon when I started and it was pretty worthless. I love my ultrasonic leak detector now!

[@sprockkets]

@@acservicetechchannel was it the ultrasonic one? Seems like accutrak is the way to go. And it seems bacharach makes clones of them too....

[@rogrog8974]

😱😱😱😱😱😱

[@DM-jf3lg]

No way I would fix that leak in that evaporator. It would be off to the recycling bin for it. Once they start to rust out like that, you just end up chasing your tail trying to fix the leaks as they pop up. It really makes the customer mad when you have to come back and find and fix a leak every six months.

[@acservicetechchannel]

Well as you can see, that is what I did with this one but some leaks are worth fixing such as at the distributing tubes or other places, or when you absolutely have to get the ac back up and running right then, thanks D M!

[@jamesfields4149]

400 dollars on Amazon......lolrofl.....

[@acservicetechchannel]

Better than (2) $200 testers that can't find anything, ha ha. My thing is when you need to find the leak, you need to be able to find it, especially when you are the business owner, thanks!

[@jamesfields4149]

I agree......are you buying them for all your service techs ....or just for yourself

[@acservicetechchannel]

I would suggest getting them for lead service techs as well. I just mean, at the least there has to be at one leak detector in the company that can be depended on to find a leak. I think there is more pressure for the business owner to find a solution compared to a technician but when we are on site, we are all in the same boat, thanks
