Well done! Concise and informative. Thanks.
AC Tech came to the house and said the Condenser Unit outside was bad (just by looking at it). Charged a $100 Fee. Gave a Bid of $10,000 to Replace Furnace, Evaporator and Condenser. Called another Tech. He said it's the Evaporator in the Furnace and not the Condenser. Gave a Bid of $6,000 to Replace the Condenser and Evaporator.
Doesn't anyone Troubleshoot anymore!?!? Two guys here and we still don't know where the Leak is...
Outstanding, Thanks for the education, ultrasonic leak detection demo was really impressive
Very impressive Craig. You are definitely the best instructor out there. Thank you for your videos.
Thank you so much for your support!
Wow, wish I could like twice! Had a leak on very similar model condenser today and found within 5 mins. Took panel off and found suction and liquid line rubbing each other. Noticed oily pipes and confirmed with bubbles. The timing of this video release is almost eerie. THANKS
Very nicely explained on different scenarios, Thanks !
You are always learning in every trade as well as in HVAC trade,
Technology is constantly evolving and the technicians have to keep up with it.
Finally got your book. Outstanding work.
I pumped a system down, cleared a restriction, vacuumed, etc for the first time today. It was good to be able to do that. You’ve been the biggest help with what I’ve been able to do. Just wanted to say thanks
Thank you so much for your support!!
Every question I had in school years ago and on the field - answered... thanks!!
Thank you for everything Craig. I have your book and it’s amazing!!!
I have used an AccuTrac for years. Depending on the system, its my go to choice. I love that thing.
Thank you for the video, it’s a great one!
I did change the entire system and couple years later, I need to add freon annual and today, 4/18, a technician told me that I should either change the whole system for $7.5k or just the cooling motor on the attic for about $2.5k in order to fix the leaking issue but now I found this video. Thank you!
Thanks for this video. My system had a small leak that I suspected was in the evaporator. But adding a pound would last almost two years when it started. Now it was 7 months. I cleaned the leaves and dirt out under the condenser looking for traces of oil. Didn't find any. But after watching this video I'm going to ask service guy to check it out before looking at the evaporator. Have a tentative appointment next April to decide if we need to replace the evaporator or install a new system. Installed in 2004. Leak started in 2018. Thanks again for the valuable information.
Install a new system. Heat pump with slimline unit. 96 efficiency is what you need.
AccuTrak ... first time I've seen someone mentioning this leak detector! Very good video.
Thank you for posting this video. I moved into a condo apartment four years ago, and the AC never worked properly. I did some research, in short, the AC is fixable. However, I had over eight technicians look at it, and they either did not diagnose the problem properly, wanted to upsell, or both.
I took upon myself to learn how to fix the AC. I would happily pay to get it fixed, but that is not an option. At a minimum, I might arrange specific repairs with a technician. I do not know enough yet for an intelligent choice. Your video brought that day a little closer.
Here’s the delema, fix or replace? .... a typical coil can be half the cost of a new unit. If it’s a leaking joint, fine... but typically where there’s one leak, there’s more. The law of diminishing returns apply. When the repair is done, what do you have? An old, inefficient, not environmentally friendly heaper, that costs more money to operate in comparison to modern energy efficient units. Then the fan motor dies.... now your costs are more than the new unit would have cost. Good Mechanics recommend replacement units because it will save money for the customer in the end. I do commercial only, and we typically make more income by repairing these older units. In the end, the customer makes the choice, after all, we work for them!
@@hvac01453 Thank you for the interest.
As I said before, I could not find an honest technician in my area. They only wanted to upsell because that is where the money is for them. My unit was not really looked at, not properly evaluated. I am learning how to make this repair, or at least how to properly evaluate my situation. From what I have seen, I Know my unit is worth repairing.
Keep up the good work love your videos and info I ought your program a lo g time ago and o still learn from you on a regular basis.
Thank you so much for this video! Very educative, very easy to watch and I would definitely look at your other videos as well.
Awesome and also check out the articles I wrote, the quizzes, podcasts and calculators at pur website at www.acservicetech.com thanks!
@@acservicetechchannel On my way right now! Thank you one more time!
I've got to save for one of those. that looks awesome.
Thank you for taking time to explain. Job well done. Now wonder hot fix these?
I am a newbie to the HVAC industry. Just started my own business 3 months ago. Your videos help with what I haven't learned yet.
Thank you for producing these videos. 😀👍
Did you work for a company as a service tech before starting your own business?
@@troymason4799 I worked for a local HVAC service co. then went solo
Tom Bork How is it working on your own?
Great video with lots of good content. Thanks!
Dude you are an awesome teacher
Craig, thank you ever so much, another interesting informative video from you
Glad you enjoyed it
Very informative. Thanks for the work put into the video
Glad it was helpful!
Thank you so much from South Africa
Nice,Thank you for sharing your idea Sir.
Godbless and more power.
You got to love A.C.Service Tech 😜
Thank you for posting nice video you can also look for treys of oil or you put a dye if the leak to small
Tip: on my heat pump after all clean I spray a clear lacquer over storage tank compressor, filters, anything painting black on steel and underneath near case attachment when spray can is full to tilt. Keep these clean especially underneath where debris like leaves can sit and rot.
I got this detector and what I can say is, it will take time to adapt to this style of alerting. The loud hissing is usually easily located leaks, you’ll know the general area, the yellow attenuation tube helps limit the reflected sound and focus the source of the leak a bit better. The smaller leaks sound more like bacon frying, a little popping sound, this is also heard in your video. I have used it to locate about 20 leaks on one unit... these were very small leaks coming thru the solder joints and verifying with Simple green as a bubble solution. Especially useful in loud factory areas.
Big blue works very well for finding leaks, and is better than just any soapy based stuff. And is relatively cheap. buy at trutechtools.com
When you get used to it. It's a must have tool.
In my company i'm the anly one having one. And the other technicians send all leak detection jobs my way.
This was an amazing video thank you for the knowledge
Thank you for watching!!
You are awesome! Thank you & blessings🤗😁
Great explanation! I have the book, but will purchase the study guide as well.
Thank you for your support! I hope you enjoy the book the workbook!
Thank you kindly for sharing.
Great video idea. Thanks for the videos
Thank you for watching!!!
Per usual awesome educational video!
Thank you for your support!
FROM CHICAGO EXELENT VIDEO THANK YOU SO MUCH
Finally just got it. My Christmas present 🎁
Sweet!
Nice ! That thing is sweet !
Great video. I have to order that leak detector. Thanks for sharing.
Thank you for watching!!!
Wow wonderful teaching
Thank you
Very good information sir
Thanks for the informative video.
What would you recommend if the refrigerant already leaked out to prevent the AC to work?
Can I still detect the leak when the AC is not working?
Thanks.
the ultrasonic leak detector is awesome
Good information!
great video thanks! I didn't know leak detection tools even existed!
could you describe how you would go about fixing a pipe with a leak? what materials and tools are needed?
thanks again for putting out such a useful video!
look up a/c leaks or brazing.
Professional. Thanks!
Thank you for your support!
i straight away subscribe to your channel.
Awesome, glad you enjoy it!
Thank you very much for your video. How much cost to call AC tech to do the leak check and the level of Freeons in Florida?
Thanks for the video.
Does the detector work even if the device is turned off?
How to fix or seal that though? Any sealer or material I can purchase to to diy please? Thanks for the great video
Wow that leak thing works good
thank you for sharing!!!!.
Thank you for watching!!
Nice video,didn't know you could find such tiny leaks using sound detection but the cost,which could be justified by a business, its just way too expensive for a diy'er.
Great video!
Thank you!
Very very good!!!!!!
How do you measure target superheat heat with the SMAN 480v? I have the wireless Phycrometers...I put one at the return grill inside for Wet bulb and the other at the bottom of outside condenser incoming ambient 😳
Excellent
Wow! No wonder AC techs would rather come out to my dad's house and put 3.5 LBs of R22 in ever 2 years instead of finding and fixing the leak. They recharge it and always recommend a new system. Never is anything mentioned about finding and fixing the leak.
You make finding the leak look easy. Fixing it would require a lot more effort no doubt and a few more videos. 😎
And it’s probably just a Schrader . Those guys are crims!
@@Froggability Maybe and that's something I can check myself. I work on car AC but don't have a license to mess with R-22.
In fact I just found a leak on my 02 Ford Focus. Its leaking at the O-rings where the lines couple up to the AC compressor. I found it with Nitrogen Pressure, soap and a gas detector. By the time I got the gas detector out the soap had started bubbling up but I went ahead and used the gas detector to confirm. 😎
There's no point to replacing a part on an R22 system. It's not worth it and are doing you a favor by not recommending repairing it, IF it isn't a coil or somewhere unfixable.
@@sprockkets it's been about a year since I spent 1600.00 on an R22 compressor install for my rental house. The new unit they recommended was 5500 bucks.
None of the different AC techs that have been to my dads even try to find the leak.
The last tech that came out put 350.00 worth of r22 in plus a service charge. Is that not easy money?
And again never even mentioned finding the leak.😀
Blade . They are crims , get yourself a bottle of water/detergent spray and diy leak check
Some nice KOSS headphones there. They could do double duty on my stereo.
I like the Bacharach H10 leak detector. Hands down best detector I've used for any refrigerant period. Doesnt matter if its r22 or 410a. If you got a leak, its gonna find it
i must be doing something wrong with my h10 havent found a single leak
@@dennyknutson9662 You know how to calibrate right? And if you can't calibrate then something is wrong. One small drop of water is all it takes to kill the sensor.
I actually found a leak Copeland compressor yesterday. Not the brazed joint but the discharge outlet port on the compressor body itself was leaking, as evident by oil and my h10 pro picked up on it. Just when you thought youd seen it all.
I've once saw on a Danfoss Manerop compressor, that it was leaking where the feets are welded to the compressor housing.
Nice job and video
Thank you!
So good..
Hi, great video. I would like to ask a question AC SERVICE TECH: Is there any other leak detector You would recommend me? I'd like to get one ACCUTRACK, but here in Mexico is hard too expensive to get one, Is there any cheaper option you would recommend? Thanks in advanced and keep with the great job You do in every video.
Very informative video, and that leak detector looks quite effective. I didn't see a reference to it in your links, could you provide again? Just a comment, I've had 2 different companies now attempt to find a major leak in my heat pump, and both failed! Almost 15 pounds of R410A leaking out within 30 days! The second guy replaced what he saw as a leaking king valve, pressurized the system and waited an hour for any leaks to appear in pressure drop, none found. First guy had filled system with nitrogen and had a nitrogen "sniffer" that found nothing. Could a tiny leak of the sort you demonstrate result in such a large and rapid refrigerant loss, yet remain undetected by these other methods? I'm pulling my hair out and considering a complete unit replacement now.
I was told by an old ac guy that most of the time its the orings or schrader valves where most leaks occur.
The one you used is the version with goose neck, but the link you listed is a different version. Which is is better? Thank you
Thank you.
You're welcome!
Great video, just wanted to know if all of these leak locations are fixable? Could you please let us know where or in which locations leaks will not be possible to fix? Thank you.
Valves are fixable
Leaks around rusted area is not worth fixing BUT we could fix them but you'll never know if it will start leaking somewhere else since it's rusted.
Condensers and coils are usually 5 years warranty, and if they are registered they go up to 10 years, if your still under warranty? Replace it, If not ? Same as above, rust cause are not worth fixing , just replace it and register it so you'll have 10 years warranty, but if it's dented or got hit like accidently wile mowing? Yes fix is worth it if it's a new unit like 1-8 years old. Not all the time 8 years old units are good but mostly they are good .
Filter dryer , joints, valves, bad brazing areas are all easy to fix and quick.
Mine a Trane 2006 Home Depot put in it and for last few year it need refill every year any ideas where leaking? my be or what could be Thanks in advance Steve
what type copper coupler fittings are used to repair liquid side 3/8 lines?
Thanks
How would you go about finding a leak in a furnace evaporator?
If other tests indicate a leak but you can't find one, would you remove the evap core to test it?
Another spot or 2 : discharge line & elbows straight after the compressor. High pressure + vibration cracks the pipe.
Pipes rubbing is another.
Yup. Found many, especially on water source heat pumps
Well I am sold on the ultra sonic. The sniffer style detectors are really inconsistent in my experience. After watching this I will have to give this type a try.
Yeah, sniffer are random, even on a non windy day. I've ordered a cheap version of this. I'll see how it goes.
ONE QUESTION. Would you recommend this ultrasonic leak detector or the fieldpiece refrigerant detector? Which one makes finding leaks easier?
I would say the ultrasonic one
Hi Crag, where can I buy the ultrasonic ,do u sell them?
Thank you so much from Sweden !
Is it possible to ship the ultrasonic detector here ?
Also, any chance of getting the booklet translated to Swedish?
Amazon will ship to Sweden. They shipped mine to Denmark with no problems. But it's pricy, but worth every swedish dollar you pay.
If it made in China, it will take 6 weeks.
Fix the visible leaks on condenser or change the condenser? Fixing the leaks seems labourous.
At 13:34 in video i wish you had explained what the different pipes were in the system. Thanks
Nice haircut and trim!
Hi, I’m interested in purchasing the e book but I have a question... I have an iPhone and a Samsung tablet... would I have to purchase two separate e-books, or could they be used in both my devices?...
If you purchase it from our website instead of apple or google play then it will work on both devices. You will just need the appropriate ereader for each, thanks!
@@acservicetechchannel alright. How exactly do you purchase it from your website?. All I see is the 2 separate app stores.
www.acservicetech.com/store and add the ebook to the cart and purchase with either paypal or credit cards. The download link will be sent to the email used during checkout. You can then open your email link on each device to download it to the device and open with appropriate ereader such as apple books app for ipad, google books app for android samsung, thanks!
Best investment ever made
Where i can order the probe for it. I have the leak detector but probe is missing.
شكرا لك اخي
What type of buddle are you using 🤔
I only use leak dye to find leaks being that 99% of leaks are in the blower coil and can’t get to every spot seeing is believing except for the Schrader pins I use bubbles every time after taking my gauges off
I've been doing hvac just over a year now and from what I can tell there isn't one brand better than the other. Do you have a preference or unit you recommend?
Loved your book BTW!
very inspiring ... good luck always ,, waiting for the next content .. don't forget to stop by my house, there are a few tips while enjoying ☕
What is the frequency of a leak in order for the detector to pick it up?
Hi Craig. Thanks for awesome videos. I did a pressure test on a system with sm480 and it didn’t drop any. Was able to vacuum fine, Freon leaked out within a week! What am I missing?
Did you pump it down? Pressure test for a while day. I've pressure tested for close to two hours and it never dropped. Found a leak in the coil
@@allanbrito13 did have sent refrigerant so nothing to pump down. Pressure tested for half hour because I couldn’t imagine N2 not dropping by even a decimal if there is leak. I cut and isolated coil , braze cores and did pressure taste and used pressure ultrasonic and soap bubbles, no leaks. Teatrera pipe as well. Nothing. Leak were on compressor discharge and suction connections! 8 year old system. I still don’t get why pressure so close to leak won’t show.
@@munawarsoomro8958 how are the Schrader cores?
@@allanbrito13 I had replaced them. But the leak was on compressor connections. Matter of fact another customer York Condenser leak in compressor connection and around high pressure safety switch connection.
@@munawarsoomro8958 glad you found it
Which of the 10 should you replace or repair?
This ultra sonic leak detector seems to work so well, i wonder why more techs don’t use it.
The price. It's not cheap.
Not all of us have $1200 plus to just blow like that.
So you find a leak at an evaporator coil, you replace the evap coil, right? You wouldn't try to patch it, would you? Would one leak probably mean another is on it's way on an old coil?
For me, if I can get to the leak even with a bit of butchery I fix it. A lot cheaper than replacing
Depends on where the leak is, how much bhttery is required to get to it, and if it is under warranty and what shipping costs are like.
9 year old unit developing rust on coil housing of unit owner wants to keep for a few years, advise owner and suggest coil be replaced.
Leak on newer unit that is easy to get to with removing metal fins or not many fins, advise the owner and suggest fix.
After watching your videos using this detector i think I'm definitely going to have to bite the bullet at some point and get it.
Is the ultrasonic leak detector better than the baccarat h10 pro??
Porye Yang my option is No. It doesn’t replace bubbles either. It’s just another tool you have in your bag of tricks to try be the best you can at your job. If your a diy person, stick with bubbles. Leaks can be the most time consuming and most common problem for hvac techs. I have 6 electronic detectors. I use mainly 3, and then bubbles to visually see the leak. The only authorized leak detection on a flat system is R22 W/ Nitrogen. The H10 is the gold standard. The Fieldpiece is better on an R410a system, that still has refrigerant (low).
Do i check leaks when AC is running?
OMG 😱 more money on tools, so my wife says. Honey….. it's a pleasure to spend money on tools like these‼️
I've been seriously frustrated trying to find a leak detector I feel I can trust given all the feedback I get from other technicians. I didn't want to spend money to have my tool be unreliable. This ultra sonic actually looks great, I figured pricing can't be that bad it looks fairly cheap. LOL that thing costs as much as a bacharach h10. I think I might prefer this though. Is there any maintenance you need to do with this detector like filter changes etc?
Im sorry, but I think the h10 is still best
@@timrob0420 I've seen this in another video side by side with the h10 and it caught it much quicker then the h10 did so I don't know about that
@@s1lvrinferno i highly doubt that. Seems like itd be hard to use in a high noise area. H10 has never let me down and it is the gold standard
@@timrob0420 You use headphones with it. Also noise doesn't affect the accutrak at all. Good to have both really, but other detectors, even from Bacharach, exceed the H10 now.
Basically, a leak could be anywhere 😂 that tool looks so useful though!
