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! :)
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
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
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👍👍
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.
Great video. I have been using ultrasonic leak detectors for testing steam traps and air leaks on compressed air systems for years. I really like the idea of using it for refrigerant leak detection.
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.
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!
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.
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.
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!
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.
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!
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!!
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!
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
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!
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!
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!
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?
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!
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.
The more I see this, the more I’m starting to like it. Got 2-350+ dollar leak detectors and still struggle to point out a leak. Specially on a windy day.
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?
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.
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
Hopefully soon i can earn the standard rate, that most of us in the trade should be getting, so i can add to patreon for your videos. I wish there was a certificate for watching x amount of hours of your channel.
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 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.
@@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!
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.
@@budgetcoolingandheating4059 You can just use that yellow tube that comes with the tool to extend it. The tool itself is what is worth the price, thanks
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?
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!
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
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.
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!
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.
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!
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!
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
