The funny thing was, i bet it was more work to cut the top of the box off and insulate it, than to just raise that ABS pipe. That was some grade A hack job. Another great video Chris
@@Starchface Those coolers are usually put in WAY early in the building construction, usually before roof drains and stuff are in, because they are so big they have to usually slide them through the open walls, plus the electrical, drainage, etc. on the really really big ones, have to be put in AFTER the cooler is in place, or adjusted at the least if you have a very good idea where its going, because its easier to adjust or put in the piping after, than it is to try to minutely move those boxes around.
He says "I know there's flaws in my installations" So humble! Chris, there are no flaws in your installations. You would be amazed what I myself have been billed for, yet I have to get someone else to fix the job afterwards.
Regarding the notch, I wonder if there might be some obstruction on the other side of the wall that makes it impossible to raise the drain pipe. Perhaps the pipe preceded the box installation and nothing could be done. I have to think there's a reason. Without knowing the situation I want to give people the benefit of the doubt. It seems like there's something cut off the end of the video. I did make it to the end and I know you appreciate it Chris. It's a crazy time and getting crazier so remember to treat each other good :).
Great video. I've done this for +25 years, I have never installed a pre charged refrigeration unit? I honestly didn't know they existed & I've installed hundreds & serviced a lot more. And customer supplied equipment, I've never heard of that either, and I've worked on everything from bar/restaurant single door reachins to +2500 sq ft two stories high walkins, not to mention grocery stores, but that's a whole different beast.(I've been out of that for awhile now, no thanks, nothing like adding four or five hundred pounds of gas to find a leak for three days) The things you learn. Don't be so hard on your installation skills, you're doing a retrofits, or as we call them, re & re's(remove & replace), there is only so much you can do to make them picture perfect, complete new installs are different, no excuses. Thanks for the informative & entertaining videos.
Good grief. I run office buildings and server rooms and don't ever let the maintenance get out of hand like this. We have a great HVAC team and don't mind at all when they've got suggestions or recommendations. It's always got to make business sense of course, but PMs and regular cleanings are a no-brainer. We see what happens when you just let stuff go.
@@BlackSoap361 Emergency repairs comes out of a different budget from preventative maintenance, and that's NOT the bottom line the people making decisions are using.
Most if not all of your customers are either in the foods and beverages businesses like restaurant, bars . Their focus is more on what they do best rather than doing primary basic maintenance like cleaning the equipment which, if you do it as an habit, you may see something out of the ordinary and be pro-active before the equipment failure. Thanks for sharing
It amazes me on how shady some of your buildings are. I would think with all of your regulations you have to do and someone gets away cutting your box like that. I would be worried about sitting on top of that box. Unbelievable!!
I can honestly say that the last few walk in freezer or cooler equipment I’ve installed checking the wiring from the factory is a must. I’ve found evap fan motors not plugged in, freezer evap coils wires incorrectly from the factory, I’m pretty sure they are having the same problem of getting food help as everyone else. I once found the nitrogen charging adaptor attached to the receiver still from the factory lol.
BTW - if the drain pipe is white it's a PVC plastic line, if black plastic you are dealing with ABS. Makes all the difference if you need to relocate or repair a drain pipe and glue the joints as a different cement is used for each.
Quick short term fix for a hole in a drain pan. Use a short sealed end pop rivet with sealer around it when inserting it in the hold. Usually 1/16 to 3/16 will seal it for quite a while.
Easy explaination for that cut out. Union job. The guy installing the feeezer was not a plumber and the plumbers were already off site. You are in California
Hello Chris. I recently stopped sending funds monthly to your channel to divert it to other interests on TH-cam. You do great work on this channel and I will stop by your live shows on occasion and support you then with some Super Chats. Have a good summer!
Your closing words got cut off :( I enjoy listening to you break everything down at the end of your videos. I am an HVACR enthusiast and your videos are so informative and interesting
Respekt for your work,your Videos and especially your mindset!!!you have What we germans called :"Rückrad"!!!IT means you re honest and Do the things the "right"way ,even if IT means that you have to work more and harder than the "others"!tahts quite rare!and i appreceate that!!!I wish you luck and health for your future!!!AT least sorry for my Bad englisch!!!
Curious what you do as far as charging the customer when you have equipment waiting at the shop to install. I’m in a similar situation not having time to install evaporators in a walk-in and I’m still working on the walk and I feel weird about charging for some of the stuff I have to do like adding gas. As a business I understand I need to, but it’s not the customers fault but I don’t have the time to do the installation of the evaporators. Any advice?
I've made that adjustment to the txv on a 404a valve when I did the retrofit. Proper labeling goes a long way. Any tech that doesn't know how to adjust a txv will say "they don't know what they're doing" however in reality the tech doesn't know what he's doing when it comes to the txv. Not saying you don't, I know you know what you're doing. Hell I learn from your vids all the time.
It is always tempting to criticize the work of the previous guys if they didn't do something the way you would expect. They may well have been lazy, incompetent butchers, but without seeing the context of what led to the situation, you don't always know for sure. What was done may have made sense in that moment. I like to give the benefit of the doubt, as long as there _is_ doubt.
@@Starchface I will not throw any tech under a bus nor will I cover for them. I just say it was this way when I walked up and the manufacturer recommends it to be this way instead. Then we talk about what we need to do to correct it and the cost of doing it.
@@thejnelson88 Yes I'm not suggesting you threw anyone under the bus. It was more of a general observation. Sometimes you do the best you can under the circumstances, and it looks bad to someone else who does not have the context. For example the situation involving the box cutout may not be what it first seems.
Thanks Chris. Could you or did you blow in more spray foam insulation above the cabinet under that roof drain pipe? Maybe about 4 or 5 cans of spray foam could top it right up.
@@bartfoster1311 Indeed, regarding that notch, my question would be, is the top of that box still constructionally in tact? Or is there a chance of it sagging or even collapsing?
@@Frankhe78 it is certainly not as strong as it was, there is just a few inches of foam and a piece of metal you could easily stick a screwdriver through remaining. I have seen the roof collapse on one that was outside because some water pooled on top.
I don't know where you were but holy shit the vermin infestation looks really bad. That and grease in the coils isn't normal in a fridge. How is grease being aerosolised in a fridge? Also the bit at the end with you talking about giving the guy ammunition is right on point, your work is your signature.
The RDI brand is sold to Distributors. It is possible the customer ordered R404 evaporator instead of R448. We build both R404 and R448 evaporators and sell to RDI distributors. If I had a serial number of the evaporator, I could verify what we built and if it was built with the incorrect TXV. I did forward your comments about the wiring to both Quality and Manufacturing. Appreciate the feedback!
lol. I'm a union sparky that works for a multi billion dollar organization, we have in house union HVAC dudes also. luckily we never see this hack crap anywhere we work. i can only imagine some of the other stuff you guys come across. thanks for the laugh
I always find it funny that my customers hold me to a hire standard. I come across the same shoddy work done by my competition, but nothing ever gets said to them. Even when I bring it to their attention, they just want ME to make it right. Had me or one of my guys had done work like that, they would have been screaming about it.
I feel you did a fine job on replacing the units. Good eye on catching the TXV's in the units. I was always taught to cap your welds and knock the tits off the bottom but over all great job...
What would be a good vacuum pump, recovery machine and leak detector that won't break the bank. The Robinair VacuMaster Economy 2 stage 8cfm, Inficon Vortex Dual and Navac NML1 look like enticing options to start out with but I've only had limited equipment experience and the equipment I learned on was TOL, I would like to eventually have nice equipment but only after I make sure HVAC is the way forward
Maybe someone mentioned this already was the 3P feed conduit to those units the right size for 8 conductors ? I'm sure you have to dance with electrical issues frequently and explain to deaf ears why they need a larger conduit or junction box. And probably wire derating over extended distances. Love this content but glad I don't do it any more too.
What was installed first? The Box or the Drain-pipe? If the box, surely some repair and re-instalment of the pipe in the correct place, plus costs to repair/replace the box?
You can't judge the effectiveness of the heat blocking compound based on the lack of oxidation (nice shiny brass) of the tubing. If the compound blocked oxygen intrusion, then you wouldn't see any oxidation, even if the temperature went higher than what the valve could tolerate.
Hi I see that you use quite a bit of field piece products like the sman 480. What are your thoughts on the yellow jacket 40870 in terms of accuracy efficiency and usability?
Curious if you’re gonna replace all that equipment why not for a temp fix to keep water under control, dab some sealant on a zip screw and plug that pinhole!
About that pipe that was cut into the top of that unit... IS it possible it was a sewer line for a toilet? Because I have seen stuff like that before. The outlet line on those things has to be slanted down right? Anyway, just an idea of what might have been going on.
Drains need grade. Sometimes the urinal can only be raised so high before only baskerball players can use it. Ive seen them install through a walkin. Through a supply duct. You only have so much room in vestibules, if youre lucky to have one. If not, well then.
Apprenticeships is critical to carry the know-how forward, the next generation of technicians need to have on hands experience. Points for having an apprentice.
Would you try to add something to the box hole to improve the insulation situation, or is that a lost cause once it's been butchered like that? Also, are you encountering more things like incorrect txv's for customer supplied equipment recently? When the equipment was delivered to shop, would it be worth the effort to go over it with a fine toothed comb to try to catch problems like that earlier?
Once water is left to condensate inside the insulation you are screwed. Only way to get it out would be to heat the box up from inside well to above ambient for a few days.
It’s funny how most of the time when people try to do things out of “laziness” it usually requires more work than just doing it correctly. I think it’s more likely that they just don’t want to admit that they screwed up. Being unable or unwilling to admit when they’ve screwed up has been one of the biggest limitations I’ve seen for people when they are trying to learn or advance in a trade. How will you ever learn to do better if you don’t ever admit to needing improvement?
That electrical wiring is really mad. There is obviously just so much you can do about it. For ease of service and system reliability I would definitely choose to run two separate cables from the main distribution panel. Just for the sake of being able to keep one unit running whilst troubleshooting (electrical) issues on the other unit. Now they are still together on the same breaker which obviously works but not quite as ideal as it could be. Well done though. And regarding the top of that box, seriously what the hack? Is that box even constructionally in tact? Isn't the whole sandwich panel the actual construction?
Why not lock the charge in the condensing unit and deal with recovery later? That way, you don’t have to haul recovery stuff to the roof….. asking for a friend…..
Rather abrupt ending. I can't believe they cut the top of the box. I wonder if the pipe going down the side of the box was too short and they didn't want to mess with making it taller. Seems like it'd be more effort and cost to do it that way than to just run the pipe higher.
as the saying goes work smarter not harder. the seems to me would take more effort to remove the top of the box and then its to move the pipe up like 3"
My 2 cents on this. Quickly get known in the food service industry as the AC tech that will rat your business out. I'm sure he mentions pest issues and other issues he sees to management but he's trying to make a living not be health inspector.

The drains are part of the building and not the unit. Likely those drains were installed during building construction and could not be touched.

Rather abrupt ending. I can't believe they cut the top of the box. I wonder if the pipe going down the side of the box was too short and they didn't want to mess with making it taller. Seems like it'd be more effort and cost to do it that way than to just run the pipe higher.
I thought r448a is a replacement for r22 and r404a wouldn't those txv work just adjust super heat
as the saying goes work smarter not harder. the seems to me would take more effort to remove the top of the box and then its to move the pipe up like 3"
Are this condensers charged from factory.... I've seen only nitrogen not freon....
You nailed it … LAZY or just plain stupid!!! I’d tell the owner to make them replace it.
so much rat poop and signs of nesting. I have a feeling you don't report your customers to the health department.
My 2 cents on this. Quickly get known in the food service industry as the AC tech that will rat your business out. I'm sure he mentions pest issues and other issues he sees to management but he's trying to make a living not be health inspector.
Lol tip of the iceberg. If you actually crawled around every restaurant you may not want to eat at the vast majority!
@@bartfoster1311 facts!
It’s one thing to refuse an ice maker cleaning saying you will do it yourself, but that rat infestation looks bad.
That's not a PVC drain line. It's ABS. You can tell by the black color (instead of PVC white). Plus it says "ABS" right on it.
Does that roof get on a top 5 dirty roof list?
aren't you blocking that roof drain with the boards for the conduit? why aren't you worried about water build up?
maybe the box was put in after the drain line and the installers hacked it up for assembly clearance?
WHAT DO YOU MEAN SYSTEM IN DECAY, AND HOW DO YOU KNOW ITS NOT LEAKING IN THAT STAGE
Was it just me or is the things we find out in the field are just hack jobs
