I've lowkey got no clue what's going on but I still love these videos, very entertaining, informative, and educative! Thanks for putting up these videos to RUclips, man!
Some twit found the secret self-destruct setting to an otherwise very reliable refrigeration system. Basically having the system set to 37 defrosts a day combined with a weak electromagnet (that slides the valve inside the tube open and closed) grounding was making the compressor fight the defrosts non-stop. The compressor won the battle but lost the war.
I'm a truck driver that works in the areas that you service. I recognize a lot of the areas you work in and I'm always looking for your van lol id be super stoked if i bumped into you.. you've taught me a lot more than I already know. And I'm very grateful for that. Great work
Thanks for sticking with the filming on this one. Never are one of your videos too long. If I see a 50 minute video post from you I know that quantity WILL equal quality, not just filler.
Watching as your acetylene ran out was some of the most suspenseful youtube I have seen in a while. Thank you for the educational and informative commentary on what appears to be an extremely complex system.
Haha.. I was really pulling for him. C'mon gas, hang in there! But yeah, at a certain point, you're going to end up with a less-than-stellar outcome that takes longer to do, from trying to make it last than just giving up and getting a new tank. When he threw in the towel, I was disappointed, but had to agree... that was the right call. (But would you expect less?)
I only just discovered this channel yesterday and I know absolutely nothing about HVAC (other than the things I've seen in the 10-ish vids I've binge-watched in the past 24 hours, lol) and I have to agree. I have _no_ idea why I was feeling on edge as he was trying to get that last braze finished before the acetyline ran out, but I was definitely in suspense, hahaha. I'm fascinated at how easily I've become _so_ engaged in this subject matter that I was actually feeling tense IRL like "oh man, dude's been there all day, dealt with several issues, and now this, is he gonna make it in time?!" lol. I had _zero_ experience with this stuff prior to yesterday, so you'd think it'd just be a curiosity to me (as opposed to a source of tension, lol). The mind is weird, and this content is awesome.
I really enjoy your videos. I actually have no interest in commercial HVACs at all. I do enjoy following your logical troubleshooting. I have experience in auto mechanics, low voltage circuits, medical care and computer networking. The techs are totally different but the process to resolve issues is very similar. You are a good diagnostician.
That was a hard one! Great job! Don't be worried about the compressor! It's a scroll and it can take it! When Copland first came out with the scroll I went to a RSES demonstration of the scroll compressor put on by Copland! In one of the tests showing how much tougher the scroll is over a recipricating hermetic compressor or a semi hermetic compressor and a open compressor a test was ran by Copland! They fed bbs in to the compressor and they shot out of the compressor because the screw inside of the compressor has an ecentric that gives when things go thru it like liquid refrigerant so it will take alot of abuse and has now become a industry standard! Remember the Dunham Bush screw compressor that was so durable that it would run for over 30 years with no problem! That is where the technology for the scroll came from! But unlike the screw compressor the scroll is made of pot metal inside and wears away eventually causing it to lock up or the shavings wear thru the armature and short out the compressor! Thanks for another awesome video! In my opinion the turbo torch would have made that job alot easier and faster! I did alot of soldering over the last 35 years and always preferred the turbo torch because the flame wraps around the pipe for even heating and you use different tips for different sizes of pipe! Also it's more economical and you don't have to worry about running out of oxygen and it's lighter and easier to handle as well!
I always hate when the torch runs out of gas on the last braze joint. You have the schlep everything down to the van and back up to the roof. The days just always seem to get longer. I appreciate and thank you for sharing your experience with us.
Why am I watching all these HVAC videos? I don't even have a central unit or any major refrigeration. I must say though, rather interesting. I love problem-solving and love "fixing things", and your videos are loaded with both of these.
Good show. When I run into problems like that, I start worrying about my skills. I end up tearing everything apart to find what caused the problem. I have seen some really strange things happen, but never like the time you found the red plastic cover in the Rotolock . But have found copper in many places it should not be. Keep up the good work. I love your show
What a pain! This happens a lot! What I mean is that you think your done...and BOOM, rare situation pops in! Glad that your real on your thoughts, the way that you record it's like a real day on the job. Nice And THANK YOU Hope You charge the client real good. Lots of work and material there. 💪
This video is a perfect example of what can happen in commercial refrigeration. Great job on diagnosis. I faced that board/valve early in my career and it threw me for a loop. Great content
I am not an HVAC guy but I worked in restaurants for 10 years. Working with Walk-in coolers air conditioning units and especially ice machines. If I had some of this knowledge back then there would have been fewer problems and we could have recognized when things were about to fail, especially the damn ice machines. Thanks for the videos.
I'm a Chef that loves your videos, it's been helping me understand my HVAC equipment a lot more, and I feel more competent at communicating with Techs about what I think is going on with my equipment. Thank you for all your content, and I love seeing the quality of your Workmanship!
Your watch makes it into view at the 19:(02) minute mark. I can't be the only one who said that is cool, I want one! What is it? If its Apple , not for me. GREAT video!! Even the calls that seem to test you, you still have a great way of explaining your troubleshooting process! That, to me is probably one of the more important things you do! Its to easy for someone without your experience to get overwhelmed by the scope of how the entire system works and not focus on step by step. For me, that's why I love watching you work!!
I really enjoy watching you trouble shoot and enjoy your videos. Personally I enjoying trouble shooting difficult issues that others can't figure out. My line of work is very different from yours. I really enjoy watching you trouble shoot. A long video and I know it was very frustrating issue but I really enjoyed it.
I actually dig the longer videos. I’m a residential HVAC tech and seeing the refrigeration side of things are interesting to me and I get a few tips on working on the commercial package units, for the few that I have. Keep it up and I’ll keep watching. Thanks for your dedication.
My engineering mind has ruined me, but I have to say it. Heat doesn't rise in a solid. "Heat rises" is a saying that people use because in a fluid, the higher temperature fluid is less dense, thus it is more buoyant and rises above the more dense fluid. In a solid, heat transfers from high temperature to low temperature, regardless of height (to a reasonable extent). Not trying to be a smart butt as you are 10x the technician I would ever be, just spreading some information about heat transfer. I am about to graduate with a Mechanical Engineering degree, and I watch these videos to learn how I can be a better engineer in the future by keeping the people who maintain the equipment happy. I love your thought process on the "whys" of failure, as the engineering students I am around rarely think that way, and that's a crucial part of why we go to engineering school. Keep up the videos; whether you're helping a fellow technician, an engineering student, or simply entertaining the masses, we love it!
If I have to heat 2 joints, one above and one below, are you saying heating the top one first doesn’t delay the amount of time the component in the middle is exposed to high temperature? If I heat the bottom joint heat rises while I’m brazing then I go to the top joint and there’s more heat all around. You’re saying the metal heats from low to high but there’s a flame that sends heat out and up and he’s trying to minimize his impact all around him especially whatever component is in the middle. But maybe I’m wrong.
@@abujamie3763 The air around the top joint will certainly be warmer than the air around the bottom joint, but the heat transfer via convection is quite minimal in the case when compared to the heat transfer via conduction through the copper since copper has a very high thermal conductivity. So what it really boils down to is the closest joint to the one you are currently heating will generally be the warmest. If you have two joints each 6” apart on a vertical pipe, then yes, the top joint will likely be *slightly* warmer. But the point in all of this way to say that heat doesn’t rise, heat transfers from warm to cool body. It just happens that in fluids, cooler, more dense fluids settle due to density differences.
AIr convection upwards will cause a little heat to increase on the uphill side. It's not a huge amount but if you heat the air, which rises and travels along let's say a rod or pipe, it will conduct a bit of heat back into the pipe on the uphill side. In the solid, inside of it, yeah...you're right.
Obviously someone set the defrost cycles to 37 thinking it was a temperature setpoint. Also, there is no way a magnetically actuated solenoid will suffer coil damage due to valve problems. The coil doesn't even 'feel' the valve being there!
> The coil doesn't even 'feel' the valve being there! This isn't strictly true. The valve position will affect the inductance of the coil, which in turn affects how quickly current ramps or decays in response to transients.
Chris, I had this same issue head-master by passing but only every now and then and then the internal scroll leaked by and fought the pressure control, this was new install only two months old and we had to install two pressure controls. Heath Craft just sent us authorizations to replace the whole condenser, everything worked like it was supported to ,for more then 2 years after that.
Chris we all have these sorts of days, you find one problem and you fix it, then it shows up another problem which then takes you on to a further problem. Good call on staying the course and chasing the ghost in the machine.

I have been repairing refrigeration, HVAC, and ice makers on commercial fishing vessels for almost 30 years. Though some systems are different, like using water to cool the condenser as opposed to air. I have picked up many good tips on checking certain components. Always try to keep learning. Thanks for sharing this great content.
I know this video was a long one but your long videos are the best ones I’m sure it was a pain in the ass to deal with all that but it makes for a very good content thanks for passing on the knowledge
Hey Chris, i been repairing lab chiller in my company. They use EEV. When i faced the symptom that temperature keeping lowering although u see the step is zero in your PCB, then i replaced both EEV coil and valve together. But what manufacture say is always keep one spare EEV coil to comfirm whether it is coil or valve issue. They dont say what cause EEV coil to fail. They say it is either coil or valve when u r having temperature unstable problems.
I show your videos, particularly this one, to my techs here in Asia. Big picture through small details. This video is super instructional. As always, thanks Chris. 🍺
I've had that happen several times with those txv and it was because moisture got in the head of the solenoid valve. If you run across that problem again take the head off the txv and dry it out good then put it back together. I've done that on about 6 of them and it fixed the issue everytime.
I think you did a very good job of all your diagnosis, I’ve had them every so often just like what you had! Hair pullers! Multiple offenders that throw you off! But your persistence was correct! That compressor within a few months weeks to a month or so is going to crap out on you. Seen it it too many t! This one is very good teachable moment! Keep it up Chris! Keep plugging!
The thermo imaging camera would have helped hear to see the head master bypassing nice job l learned a lot here I was ready to replace the compressor again nice job thanks for the video
The simple answer is “ That Beer can NEVER be too COLD !!! “ Good vid ! Yes , that scrap of copper was from someone cutting or Reaming a Pipe poorly and Leaving a Shaving hanging inside the Pipe. It finally detached it self from the tube and blew its way down the pipe. Great find !
Carel e2v coils fail often here in uk (aldi supermarkets). When the coil goes faulty the body is stuck in its last known position regardless of what steps it thinks it’s at. Probably just a new coil needed but nevertheless job well done. Keep up the good work :)
...and of course Carel will just refuse to sell the coil. Even if the EEV was mechanically stuck, it really wouldn't cause the coil to burn out since the control doesn't continuously keep stepping the valve.
Pre-made flares? Blaspheme! Jokes aside I avoid pre-made flares because they tend to break if you re-seat them as low as 3+ times. It's just the way they are manufactured making the back of the flare thinner. Love the videos btw. Its priceless exposure for resi comfort cooling techs wanting to learn more about commercial HVACR. Definitely turning my apprentices onto you.
Sounds like you're having as much fun as I did today I live in Greenville South Carolina and we just got slammed my hurricane Zeta trees down everywhere big tent no longer big Palace crafts but Keep On Keepin On
You can always use the silica inserts on a leaking flare fitting to get it tight and no leak.. they are a life saver. I was wrong on FB about wrong refrigeration. But you said something out of the norm
Perfect gob hi Lauren every year with your videos thank you so much appreciate thank you again we lord we learn we still learn thank you my friend I am Mexicano
You are a thorough kik ass tech i just learned a ton of shit from you i love refrigeration but have only done simple fixes you are the man im going to subscribe!
Christ this video was brutal to watch. The highs of replacing the expansion valve, the lows of seeing the bypass triggering, the further lows seeing the outdoor light gradually turning to evening with no end in sight.
Those pesky hot gas controls can cause lots of problems. When you replace them, make sure to don’t install the new ones without first making sure to order two inlet screens first, they unfortunately are Considered optional, don’t ask me why... also when you have the king valve front seated, and the gauges on the left service valve, how do you expect to read the compressor high side without an additional pressure gauge on the discharge line. If you had, you would have likely seen the head pressure climbing way up
Great job. That was some interesting finds and the fact the system worked that long. And how did it get 37 defrosts? Crazy! Makes you wonder if the managers friend of a friend had been in there pushing buttons.
So this might sound like a very rookie question but I'm only a few months into my HVAC career so there is still a lot for me to learn. In this video at about 13:06 you say " normally you dont want to cool a braze joint" ... Why dont you want to? Does it make the connection more brittle? I apologize for the ignorant question but I'm trying to become a better technician.
I've lowkey got no clue what's going on but I still love these videos, very entertaining, informative, and educative! Thanks for putting up these videos to RUclips, man!

Another excellent job and video 👍👍👍
Then I was able to watch the whole video. How hard you have worked. I wish you convenience🙏🙏🙏
Sounds like you're having as much fun as I did today I live in Greenville South Carolina and we just got slammed my hurricane Zeta trees down everywhere big tent no longer big Palace crafts but Keep On Keepin On
Thanks for those videos was a pain but u got through it ! Keep it up
Great job and video like always
You can always use the silica inserts on a leaking flare fitting to get it tight and no leak.. they are a life saver. I was wrong on FB about wrong refrigeration. But you said something out of the norm
Great video thank you so much!!!!!
Heatcraft got me in a similar way, had a copper curly-q in a headmaster a couple years ago
wow wow chris this one was very very interested
Perfect gob hi Lauren every year with your videos thank you so much appreciate thank you again we lord we learn we still learn thank you my friend I am Mexicano
When i chance a scroll compressor a always put a onway vale in the hot gas pipe so the gas won’t return I’d the bypas is broken
Excellent video, great info
You are a thorough kik ass tech i just learned a ton of shit from you i love refrigeration but have only done simple fixes you are the man im going to subscribe!
Great video. Thanks for sharing.
Great work as always and thanks for the content stay safe and take care
this was a mess but it gave us a extra long video and i enjoyed every second of it :D
Then I'm thinking probably the board. Then I hear it from you 2 seconds after I continue the video. This is hilarious! Somebody stop me!
Christ this video was brutal to watch. The highs of replacing the expansion valve, the lows of seeing the bypass triggering, the further lows seeing the outdoor light gradually turning to evening with no end in sight.
Truly a saga any engineer knows :(
Those pesky hot gas controls can cause lots of problems. When you replace them, make sure to don’t install the new ones without first making sure to order two inlet screens first, they unfortunately are Considered optional, don’t ask me why... also when you have the king valve front seated, and the gauges on the left service valve, how do you expect to read the compressor high side without an additional pressure gauge on the discharge line. If you had, you would have likely seen the head pressure climbing way up
I had the same problem and it was reading some real wackyshit and it was the TXV AND the HGB. I think when the HGB fails it kills the TXV.
Great job. That was some interesting finds and the fact the system worked that long. And how did it get 37 defrosts? Crazy! Makes you wonder if the managers friend of a friend had been in there pushing buttons.
They must been hitting the crack!
I guarantee you someone thought they were setting it to 37 degrees. 😆
So this might sound like a very rookie question but I'm only a few months into my HVAC career so there is still a lot for me to learn. In this video at about 13:06 you say " normally you dont want to cool a braze joint" ... Why dont you want to? Does it make the connection more brittle? I apologize for the ignorant question but I'm trying to become a better technician.
@@radio.computer thank you for your feedback, i will adjust how i braze from here on out
Wow, that was some job! Fantastic job! well done 👏🏻👏🏻👏🏻👏🏻
I fell asleep a couple times but I slept-learned what you were doing and oddly followed along the entire time!
One of those calls man !
You gotta think fast, think logically and act quickly. 👍
Wow I couldn't believe that you had that much patient with this job 🏃♂️🏃♂️🏃♂️
Great video Chris. That was a hell of a call.
Like the troubleshooting. Make it right...
