Kitchen calls are year round, lack of maintenance, I’d sooner keep a good Resi customer and tell the restaurant to F off, because they reduce maintenance and call you on a long weekend because walk in cooler not working, ie, subway
@@justinperry68 you really on some BS if you telling a customer to “F-Off” either you lying or you just don’t have any common sense. This industry does not need goofies like you.
Electrician here with hopefully a helpful tip. The capacitor function on a multi meter measures the time to charge a capacitor, if a cap reads high it can actually mean the cap is leaking current internally (takes longer to charge) and has in fact failed.
To add: Bleed down resistors have the same effect, and I assume the one on the start cap in the video was contributing to the high reading. Unfortunately they're usually soldered in so rooftop testing becomes a bit of a hassle.
@@PimpMyPc89 cut them off and carry replacements with female spades on the end or you may be able to cut one side loose and use a flag terminal female to reconnect.
@@PimpMyPc89 - my electrical box has a battery powered soldering iron (batteries stored outside the iron), and lead based solder with good flux. I don't need it that often, but when I need it - it's there.
These cooks really have trouble keeping their drawers cool, perhaps a personal swamp cooler for each employee would help... Ohhhhh, those drawers. Gotcha
You're not crazy, just preventing future problems by being attentive and proactive. That's the exact spirit maintenance/service should have, applies to your tools just as much as it does the customer's equipment.
I remember a package unit that would leak all the time. After changing out the condenser and the evaporator, which both had pinhole leak, The Compressor was changed out stopping the leaks.
I find it helps me during busy season to pack a big bag of almonds and bring protein shakes with me. During this time of the year eating doesn't sound good at all. All I want to do is make repairs and move forward. Little sugar and protein will pull you right out of mush brain if you don't want to eat a full meal.
Yet another brilliant video Chris, perfect camera shots always, it's easy to forget the trouble you take to set up these views and in those baking conditions too and you even jump into your seat for the overtime channel. Well done mate.
Not sure if its just the way it looks on camera, but that flame is so cute. Most guys ive ever seen just go with a single tip for everything and turn up the flame until it drowns out all sound.
Florida guy use to the high heat, why don't you take up a pop up canopy that'll cover at least you if not the whole unit? Single person setup and take down just hook and pull up from the roof? 20 mins to set up but cut the heat and uv drastically and be healthier. $150 well worth it.
@@robertthomas4633 no considering you normally take 150lbs of tools up there's other ways to weigh it down besides sand bags. However, yeah I'd gladly rope up 4 10lb bags at the start of a job to not work 4-6 hrs having a heat stroke etc with temps regularly over 110+. Small extra effort to make you not get brain fried and make dumb mistakes or feel dead at the end of a service call. We do it all the time here.
When it comes to stuffing your face with food. Maybe you should have a bag of nuts and/or beef jerky or other food stuff that doesn't need to be kept cold in your go bag
Dried fruit, beef jerky, and nuts. Avoid straight sugars like chocolate. The fruit gives you a quick boost of energy, the jerky isn't a lot of calories, but it's slow calories. The nuts have more calories than the jerky, but don't last as long, but longer than the fruit.
Start relay?? The start and run caps are just part of the circuit. So many times the start relays contacts are so pitted, the start cap won’t electrically be in the circuit. If you can’t disassemble the relay to inspect, use amp clamp around one of the start cap wires to verify current flow. It’s not fun replacing a compressor for a misdiagnosed electrical problem…
Good point. I still had one where I found the start relay going bad and put in a universal but next day the compressor died, of course on the weekend and there was no replacement compressor in the area. After replacing compressor, system flooded back bad from just the drawers, adjusted one of the txv and got it under control and now they keep freezing up their coils with not closing the drawers. What can you do at that point except telling them they need to close the drawers.
If the startwinding wasnt in the circuit, it would never pull 30+amps. However i found it weird that he measured 6v drop across the overload, but he got that out of the circuit anyway.
Really appreciate these videos. Recently started my position as an hvac tech and these videos are incredibly helpful. Thanks for taking the time to do these on top of your weekend service calls. Thats a lot of work but these videos are invaluable!
Customer: you done yet? Me: nope Customer: well I have to leave in an hour so…… Me: k we can reschedule you for next available appointment. Customer: no that’s fine I’ll wait. I need it fixed.
If water is a problem when doing a wash on the coils suggest a drain pan under the roof. Considering the amount of rain in your area it will only be used when you wash the coils. Thxs for the vids!
Chris, you have a nice taste in music. I always enjoy your production style. And in a general since it’s funny how on a high basic level I can somewhat understand how hvac works. And I’m on the IT industry. Your videos are always informative and I enjoy them. Good job man!
I empathize with everybody on the west coast with the heat wave y'all been getting also happy birthday to your daughter hope you guys have a great time sure you will
Nice and tidy isn’t crazy. Professional sloppiness is. Especially if you bill by the job. Also, get a couple small flare nut visegrip pliers. They make a great soldering stand and can also act as a heat sink on tubing if you need to protect components down line from torch heat.
Totally feel ya on the the eating bit. I'm not a fan of eating breakfast, but when I was working production side oil & gas I had to make myself eat breakfast on top of packing a good sized cooler of food, water, and gatoraid.
Damn Chris. We appreciate your time with this. It'd be easier for you to just quit RUclips and focus on your family and job but we do really appreciate you putting these videos out.
it's nice to see that even though you are super busy, your attention to detail does not slack. there's nothing worse than a tired tech throwing crap together just to "get it done"
I know nothing about HVAC but find your videos incredibly informative. I can tell you know what you are doing and take pride in your work. Being neat is part of it. Organization leads to efficiency. I have a couple of classic British cars and keep my tiny garage neat and tidy as well. I was never so excited as when I got a peg board and hung all of my wrenches.
the factory bleeder resistor in parallel with the capacitor will throw the meter reading off, possibly way off if the cap is very weak. it's dependent on the resistor composition type also. some are far more inductive/reactive. cut one out and put you meter across it only, lol
One thing that might help you in the long run - Offering basic maintenance courses for rooftop units and kitchen refrigeration. It would save your customers money too. I feel that every business should have PM manuals, but nobody seems to use them.
Hey Chris, just wanted to say that bending the end of your brazing rod is a great trick, if I hadn’t seen it here I would have had a hell of a time under my sink today! I’m not in HVAC, but I always watch your videos and that helped me out a lot!
"I'm thinking about the next guy" - dude, this is such a powerful and professional mindset to have. It is a critical skill for a good workplace but it is such a rare skill to see being utilized by a team.
That's one of the reasons I detest zip ties. (binder straps) I use wire ties (bread tie style) or velcro straps for anything that I think might possibly need to be accessed prior to complete replacement.
Kitchen production workers are a pain in the ***. I just tell them the worst-case timeline and let them deal with it. Honestly, if the production is so damn critical they need to install backup freezers & coolers. On my favorite freezer install, I was able to use a dual condensing unit with a dedicated evaporator for each. Each is about 80% of the -10f load. This has paid for itself a dozen times. A single unit can hold the box @ 20f for as long as needed to repair the other unit.
Great video as usual bro and I don't think I've ever disagreed with any of your techniques before but something I see you do in most videos while brazing I'd like to give you some advice on, while brazing,soldering, you want to heat as well as braze from the bottom to the top. Heat rises as you know so when you start on the bottom the heat rises to the top of the fitting so once you get the bottom hot enough to flow, it takes very little heat to bring that flow up and around the fitting to the top, you can back your flame off once you start getting towards the topside, doing it the opposite way, you can actually overheat valves and such because your topside is already hot enough, then you go to the bottom and you heat it up even further. You will also notice better looking braze joints as the metal isn't heated up as much so there will be less discoloration. Especially on vertical joints, you'll be amazed that you've been doing it backwards all this time lol. Sorry bro but I just wanna help you out, you're a great tech. Thanks for the videos
You’re one of the best Unitary guys on YT. Your LC HVAC/R skills are tip-top, and your extra work will be appreciated by the next Tech after you. Some guys favor what they do (usually a step up) an Applied/Engineered Tech may say for you to get into Chiller or Boilers, and a ComRef guy may say for you to get into C/S Racks. It’s all HVAC/R, and there’s room for everybody.
Ok. Im glad you showed all the shit we have to carry onto the roof. It’s really exhausting . I like your OCD. Im there myself. I just cant talk as much as you do. My speech centers shut down when I’m hustling and hyper focusing. Yea, the hook, I love it. I have it. Here’s a trick. If you get an old fan belt and wrap around items, you can easily hook on to them.
I work in the Home Appliance and Refrigeration field we are fortunate that most Condos and HOA's will kick us out at 5pm. So we're home at a decent time. Also most of our parts are not locally available we work on a lot of Korean and European products. So we have to wait about a week before going back.
Did you check that potential relay? Chances are the contacts were burnt and pitted, which can cause the compressor not to start and even trip the breaker. Carry a small metal nail file to clean the contacts. If other components are acceptable, you can at least see if the compressor will start and run. If it will run and check ok, then you can return with new components. A starting cord also comes in handy to check a compressor with bad starting components. Your rope hook is awesome. One way I lower everything down is to have a rope at least twice as long as your drop, lower it down, let go of one end of the rope and pull it up empty. Just make sure loose end won’t snag on something. Easy way to do it when you have to lower all that equipment!
Rope and hose management...oh we're so much alike...probably if you look up OCD in the dictionary you'll probably see both of our pictures! ;-) You might consider getting a Peak Co. Equivalent Series Resistance (ESR) meter to double check electrolytic caps as they may show the correct capacitance value but have a high ESR (read that as bad). I gave my HVAC buddy one and he uses it all the time to check run caps on the residential systems he services. Thanks for another great video Chris!
I had a single-phase 18 month-old Russell condenser for a walk-in cooler just do this exact same thing 2 weeks ago, but it was just the start relay. Swapping a relay first seems like an easy/cheap test to execute before condemning a compressor. Not sure that was done here? My unit would pull locked rotor current and trip breaker. Original installer came out, said it was a failed compressor and $2400 to replace. I had a hard time believing that a nearly-new unit failed, so I looked at it myself, swapped out the start cap (bad/open) and the relay and it then worked perfectly. I cracked open the bad relay and one of the contacts had it's rivet loosened up a good 1/8" and it could make partial contact even when open, so the start cap wasn't always being completely taken out of circuit, which eventually blew it up. I am not even an HVAC/R tech but I managed to properly diagnose and repair my issue for under $50, so my service company either has moron techs or were just trying to take me for an expensive ride? Either way, they are now fired; can't trust them. In the case of this vid, a good start cap paired with pitted relay contacts could also result in a compressor not starting even though the cap might see some trivial current through the relay - still enough to heat up the cap, but not enough to spin up the rotor.
Chris, do me a favor, and thank your father for me for giving you his attention durring your growing up because your skills and attention to details is obvious to someone with a trained eye, and it all started for you by being around someone when you were young, and that someone cared enough to show you the right way, and now you have taken that to the nxt level, I'm picking up the details of your moves and sequences without you saying a thing about what moves I see you doing, your bringing my knowledge I've had on shelf for decades back up to speed very quickly. Thank You very much, I will ask you questions when I think it's a good point to understand better what your doing. Just like the question I asked, have you ever added oil to a system as a possible problem with other factors in doing a repair to cover all bases in that repair.
Doing a voltage drop test, nice! I’m always chastised for doing that, “don’t test live” etc. can’t tell you how many partially blown fuses I’ve found that way…
I'm the same way with eating. I just want to keep working to get done and never think about it. But if I have someone helping me then I remember because I make sure they eat lol
I watch those misters, and think "Gee.. Here, they just get you soggy." - Houston, Gulf Coast, humidity under 80% is considered dry. Swamp coolers rarely work.
Some people; you say don't put x in here and it's like in one ear out the other, it just doesn't click! They'll even give you all the right sounds! Maybe ask them something that leads to them replying with "that's right"!
I bought one of those hooks the first time I saw you use it. Everyone made fun of me till they realized it meant much fewer trips up and down the ladder.
You push it to the level of an art...that's what makes it interesting to watch...speaking as an emergency nurse...make sure you keep your electrolytes up too...Gatorade or pickle juice will do...🤔🤷♂️ make sure you know the signs of heat related illness and take breaks or your body will...and make sure you have adequate input/output...keep up the amazing hvac...and stay cool
I have a 9' umbrella for shade when I have to be on the roof for an extended period of time. Use the ropes to tie it off on 3 points because the wind will blow it over. $30 for the umbrella and the base is $20 at Academy. Not a roto lock fan. Just more potential places to leak. txv needs to be adjusted if it's flooding back. I will take at least 3 ropes. I like the hook idea. A link would be great. Did you run an acid test on the old compressor? Those type of coolers either leak on the evaporator, flex lines behind the unit or pressure control. You never have to evacuate a system for a bad pressure control. Just pinch off the cap tube. Get a 1/4" male flare coupling, 1 flare nut a piece of 1/4" tubing. Flare the tubing and install the coupling. take your pinch offs off of the cap tube and shove it thru the tubing and out thru the coupling several inches. Reapply your pinch offs. crimp the 1/4" tubing on to the cap tube. very low flame and solder the cap tube to the 1/4" tubing. use the edge of the file and score the cap tube about 1" where it is sticking out of the coupling and break it off. Now quickly connect your 1/4" flare nut form your new pressure control. If it's the low pressure I let it go to pump down so the pressure is inly about 5 to 10 psi. If it's the high side I let the unit get to temp, shut it down and equalize the system and most of the pressure will run to the evaporator and you will have a low high pressure. Your soldering process should go very fast no time to dilly dally.
When a pro like you says that you just hope that you did everything right it makes me feel better that im not the only one that second guesses himself. lol
Did you check the potential relay. It would cause the same symptoms as a locked up compressor by not taking the start winding out of the circuit? Love the videos.
At the end of the video, Chris said he took out the potential relay and tried starting with an amrad start cap. Gotta watch all the way. There is just as much info in the closing words as the video.
He said he replace the “ start capacitor” with a universal one. I watched and understood. Not the potential relay. It you don’t put an amp meter on the start winding wire that goes to the potential relay and watch it drop out. Gotta listen
Ok. Thanks for clarifying. Never used those. Isn’t no telling how many compressors have been replaced due to bad start/ potential relay. Thanks again should have known better. Chris is a very good tech love the videos.
Hey Chris!, surprised you didn't check the compressor's winding resistances first. I usually do that first because if they are way off spec well its gone and not coming back...
I love that Chris always purges with nitrogen when he brazes. I work with so many people who never purge and it makes me so mad. They are just lazy. I always think in my head "dude, just do your effing job the way you are supposed to." It's not that hard to drag your nitrogen tank out and purge. Just do it!!!
If you designed factory units, they would be much easier to service and maintain, and might last much longer... leading to the sales of less factory units.
Almost all kitchens iv cooked in its our under counter fridges that leaks . But also we have no a/c in none of our Canadian kitchens lol so I'm sure a lot of our equipment work on over load
Great job Chris and apprentice I feel for you with the heat it must be a killer? Good choice of music keep safe and try and stay cool if you can with the heat 😉
Man I wish I could spend a week with you picking your brain…I don’t solely work on coolers/freezers/cook drawers but I seem to be the only guy with enough knowledge (or at least willing to) work on them and I only know a small fraction of what you do.

Morning Chris , already know it’s gonna be a great video!!! I hope you have a great day
Nice pipework. Like the Schrader tee for pressure port replacements. Gonna have to steal that idea. Thanks.
Dont know why, but i love how new copper looks
Rope and hose management...oh we're so much alike...probably if you look up OCD in the dictionary you'll probably see both of our pictures! ;-) You might consider getting a Peak Co. Equivalent Series Resistance (ESR) meter to double check electrolytic caps as they may show the correct capacitance value but have a high ESR (read that as bad). I gave my HVAC buddy one and he uses it all the time to check run caps on the residential systems he services. Thanks for another great video Chris!
Happy birthday to your daughter. Stay safe in that heat. I've almost had a heat stroke and it sucked
11:35: Check out the compresor-killer come out of the nitrogenated line when he hits the new joint w/ the torch.
I had a single-phase 18 month-old Russell condenser for a walk-in cooler just do this exact same thing 2 weeks ago, but it was just the start relay. Swapping a relay first seems like an easy/cheap test to execute before condemning a compressor. Not sure that was done here?
My unit would pull locked rotor current and trip breaker. Original installer came out, said it was a failed compressor and $2400 to replace. I had a hard time believing that a nearly-new unit failed, so I looked at it myself, swapped out the start cap (bad/open) and the relay and it then worked perfectly. I cracked open the bad relay and one of the contacts had it's rivet loosened up a good 1/8" and it could make partial contact even when open, so the start cap wasn't always being completely taken out of circuit, which eventually blew it up.
I am not even an HVAC/R tech but I managed to properly diagnose and repair my issue for under $50, so my service company either has moron techs or were just trying to take me for an expensive ride? Either way, they are now fired; can't trust them.
In the case of this vid, a good start cap paired with pitted relay contacts
could also result in a compressor not starting even though the cap might
see some trivial current through the relay - still enough to heat up the cap, but not enough to spin up the rotor.
I will discuss this on the stream tonight 7/12/21 @ 5:PM (pacific) come check it out ruclips.net/video/sSZgwI-oduU/видео.html
Chris, do me a favor, and thank your father for me for giving you his attention durring your growing up because your skills and attention to details is obvious to someone with a trained eye, and it all started for you by being around someone when you were young, and that someone cared enough to show you the right way, and now you have taken that to the nxt level, I'm picking up the details of your moves and sequences without you saying a thing about what moves I see you doing, your bringing my knowledge I've had on shelf for decades back up to speed very quickly. Thank You very much, I will ask you questions when I think it's a good point to understand better what your doing. Just like the question I asked, have you ever added oil to a system as a possible problem with other factors in doing a repair to cover all bases in that repair.
HVACR VIDEOS Trade mark phrase : "I really really......". 😆 😅 😂 🤣😆 😅 😂 🤣
Doing a voltage drop test, nice! I’m always chastised for doing that, “don’t test live” etc. can’t tell you how many partially blown fuses I’ve found that way…
Some costume don’t understand how much work is changing a compressor it’s time consumer special with roof equipment
I'm the same way with eating. I just want to keep working to get done and never think about it. But if I have someone helping me then I remember because I make sure they eat lol
Looking forwards to the autopsy on the dead compressor
Thanks again for a informational video Chris !
Damn your a genius using a mister to cool yourself off damn I wouldn't even have thought of that nice bro
I'm glad you have the compressor for autopsy, I find them fascinating.
Damn i commented before watching........the 80's brazing music is back........hell ya.
Nice to hear you're attentive to family despite the work load. I know - I've been there
Love that mister idea! Keep it up!
You really need a tent on the roof if you’re gonna be up there all day
My hook came in yesterday! Stoked to use it
I watch those misters, and think "Gee.. Here, they just get you soggy." - Houston, Gulf Coast, humidity under 80% is considered dry. Swamp coolers rarely work.
Proper setup and preparation is like half the job and the time you take to setup usually is time saved in the long run 👍great video man
Some people; you say don't put x in here and it's like in one ear out the other, it just doesn't click! They'll even give you all the right sounds! Maybe ask them something that leads to them replying with "that's right"!
I now have to play that music while I’m brazing! Awesome!
Gotta get me one of those hooks. I seem to find getting my equipment up to a unit to be probably in the top 5 biggest pains in the ass about this job.
You are performing a braze, sweating copper involves using low temperature solder
I bought one of those hooks the first time I saw you use it. Everyone made fun of me till they realized it meant much fewer trips up and down the ladder.
Soldering 80s tune was awesome!
You push it to the level of an art...that's what makes it interesting to watch...speaking as an emergency nurse...make sure you keep your electrolytes up too...Gatorade or pickle juice will do...🤔🤷♂️ make sure you know the signs of heat related illness and take breaks or your body will...and make sure you have adequate input/output...keep up the amazing hvac...and stay cool
Hallo Chris, ich komm aus Deutschland bin selbst Kältetechniken , ich bin begeistert von dein Videos danke da für
I have a 9' umbrella for shade when I have to be on the roof for an extended period of time. Use the ropes to tie it off on 3 points because the wind will blow it over. $30 for the umbrella and the base is $20 at Academy. Not a roto lock fan. Just more potential places to leak. txv needs to be adjusted if it's flooding back. I will take at least 3 ropes. I like the hook idea. A link would be great. Did you run an acid test on the old compressor? Those type of coolers either leak on the evaporator, flex lines behind the unit or pressure control. You never have to evacuate a system for a bad pressure control. Just pinch off the cap tube. Get a 1/4" male flare coupling, 1 flare nut a piece of 1/4" tubing. Flare the tubing and install the coupling. take your pinch offs off of the cap tube and shove it thru the tubing and out thru the coupling several inches. Reapply your pinch offs. crimp the 1/4" tubing on to the cap tube. very low flame and solder the cap tube to the 1/4" tubing. use the edge of the file and score the cap tube about 1" where it is sticking out of the coupling and break it off. Now quickly connect your 1/4" flare nut form your new pressure control. If it's the low pressure I let it go to pump down so the pressure is inly about 5 to 10 psi. If it's the high side I let the unit get to temp, shut it down and equalize the system and most of the pressure will run to the evaporator and you will have a low high pressure. Your soldering process should go very fast no time to dilly dally.
When a pro like you says that you just hope that you did everything right it makes me feel better that im not the only one that second guesses himself. lol
Did you check the potential relay. It would cause the same symptoms as a locked up compressor by not taking the start winding out of the circuit? Love the videos.
At the end of the video, Chris said he took out the potential relay and tried starting with an amrad start cap. Gotta watch all the way. There is just as much info in the closing words as the video.
He said he replace the “ start capacitor” with a universal one. I watched and understood. Not the potential relay. It you don’t put an amp meter on the start winding wire that goes to the potential relay and watch it drop out. Gotta listen
@@FPHA697 when putting in an amrad, it has a built in potential relay, therefore removing existing out of circuit.
Meant no disrespect.
Ok. Thanks for clarifying. Never used those. Isn’t no telling how many compressors have been replaced due to bad start/ potential relay. Thanks again should have known better. Chris is a very good tech love the videos.
I will discuss this on the stream tonight 7/12/21 @ 5:PM (pacific) come check it out ruclips.net/video/sSZgwI-oduU/видео.html
Hey Chris!, surprised you didn't check the compressor's winding resistances first. I usually do that first because if they are way off spec well its gone and not coming back...
Dissimilar metal brazing with the royalty-free 80's synthpop is always a jam.
I love that Chris always purges with nitrogen when he brazes. I work with so many people who never purge and it makes me so mad. They are just lazy. I always think in my head "dude, just do your effing job the way you are supposed to." It's not that hard to drag your nitrogen tank out and purge. Just do it!!!
Sometimes I think I even have the spare tire up there. Lol. Nice job, stay safe.
If you designed factory units, they would be much easier to service and maintain, and might last much longer... leading to the sales of less factory units.
Almost all kitchens iv cooked in its our under counter fridges that leaks . But also we have no a/c in none of our Canadian kitchens lol so I'm sure a lot of our equipment work on over load
Love your work!..Cheers from Portugal
Look at all those tools! There should be a $100 extra charge just for getting them up & down from the roof.
Great job Chris and apprentice I feel for you with the heat it must be a killer? Good choice of music keep safe and try and stay cool if you can with the heat 😉
8:03 beautifullllll
What music plays during braising I LOVE IT
Lupus Nocte - Milky Way Express
Would be nice if they had a parking spot for your van up on the roof then you wouldn't have to haul all that stuff up the access hole
Nice Brazing montage - definitely an '80s vibe!
Good job Chris.
5:50 specially doing commercial work alone sheeet sucks but that saves your aze from getting tired hood video Chris 👍
Man I wish I could spend a week with you picking your brain…I don’t solely work on coolers/freezers/cook drawers but I seem to be the only guy with enough knowledge (or at least willing to) work on them and I only know a small fraction of what you do.
