OUR ENTIRE COOKS LINE IS WARM 

I appreciate you being honest and talking out your mistakes for clarity. You could've deleted it but you didn't. Raw. Good shit. And because of that I learned - Compressors sound funny backwards lol

so.. i noticed today.. when watching your vids.. wich i found only yesterday.. that i get so into the vids i clench my hands in anticipation occasionally s you try to solve problems lol. this beats netflix anyday :)

I didnt think, I would ever see an AC leak that bad...........what a geyser!

My all time favorite story is on a mall rooftop another tech was a distance away working on one store unit, found low charge then produced a really long hose which he connected to another store's unit. He was able to charge his unit without carrying a jug up on the deck. Plus he got a service call from the other store owner the very next day:) Will never forget that one.

Love when you said “FIRE” can’t tell you how many times I’ve lit em up inside McDonald’s and forgot to mention it and it scare the crap out of them lol.

You went above and beyond to save that compressor(s), most guys would have gone "gas-n-go". My old company would say "it's old and beat up just replace the compressors and clean the coil". This is a small business and you did try your best to save them money, and that speaks volumes about you. Peace brother!

I appreciate the time you spend on sharing your knowledge and experiences.

Typical in the restaurant industry. When one thing takes a dump, they just move to the next piece of equipment until it breaks, and so on.

Not an HVAC tech but somehow this is still one of my favorite Channels.

I live a chill life, work my 8 to 5 job in the hvacr industry then get home, see Chris uploads a new video and my attention is here for the next hour lol

For a motor it is usually in the 10 to 15% range. If you suspect that it is the motor try this test, Move all of the phase connections one step ahead. A to B, B to C and C to A. This will not change the rotation of the motor but it will show you if the unbalance moves ahead with the new connection.

I love when you say: ,,sometimes this is what you have to do'' because it's true, on the residential side when we deal with 7-8 calls a day in the summer months it's impossible to be perfect every single time because the bottom line is to get them up and running.

This video ably demonstrates the pressure your under to keep these business running.. Well done .

Best way to end a Friday

I want to be like you when I grow up. Great video Chris. 💪🏼💪🏼💪🏼

Loved the way you put on that power head like a recoil pull start! I'm always learning something handy from your vids. Got other techs at my shop watching you too.

Multiple leaks and problems that are caused by them,,,.. You have the patience of a Saint.

we've been blessed with a 50 min video fellas let us say thanks

You and Curious are too honest and everyone should appreciate that since we have all dealt with the same bullshit. Great video!

YOUR OLD CONDUCTOR WAS BLACK,BLUE AND RED... AND THEN YOU PUT IT BLACK, RED AND BLUE... WE ARE NOT PERFECT BUT WE LEARNED ... GREAT VIDEOS...

I ended up here three days ago from a random recommendation, I have not watched any other videos. I knew very little about HVAC but learning all of this has been super awesome.

Can you cut the top off of the old compressor? If so, maybe that black stuff is in the compressor. I think compressors have a mesh screen at their suction opening. If that screen is clear, but that black stuff is also found in that compressor, then it may have originated from the compressor. A chemical analysis of that black stuff is probably the only sure way to identify it. Thanks for bringing us along!

Not trying to take a stab at you because you have taught me alot, but when you change contacts it is worth looking at the 2 over to the left and try to keep colors and everything organized for the next guy. Everything was perfect before and now it's just all over the place. I've followed this kind of work before and change it all back out of frustration. I just mentioned this because I know how adamant you are about keeping things professional and top notch. Plus it's a good practice to get into doing. Nice video, here is a like. 🙂

0:21 I was like: I've never heard my phone make that noise wtf?

I'd be honest, this is the 1st video that's 1hr+ that got my attention!! I've done reefer work before and we all find weird stuff so I've seen cluster f's a lot!! Had one with a a.c. system yesterday and at the end got it running up again!! Like the videos but miss the short ones!!

We definitely try our best to pull perfect vacuums, braze with nitro etc. but the main thing we need to do is get the customer back up and running. Had plenty of jobs like that one. Great vid

everything is built to a price, that is your starting point - a wise person once said"you just have to deal with it"

These videos are great. I learn a lot more from seeing what to do.

Great video as always. These are starting to get me interested in the HVAC field

As Sister Hazel would say , I hope you realize how much your knowledge helps not only the younger guys in the trade but the older guys as well ... You rock Chris ...

My company here in Bermuda has been shut down for a month now. I just found your channel and have been binge watching your vids and they have me itching to get back in my truck.......and I never even enjoyed the restaurant side of the trade. Good work though my friend.

These videos are awesome keep doing what you do! I really enjoy watching them. Now I get to see what its really like and the pressure you’re under to diagnose and repair a problem to get your customers up and running! Looking forward to another video

Been learning alot just from watching and listening thank you

I like your thought process.keep up the good work.

Great video bud. Thanks as always

Another great and informative video! Thanks Chris!

Great job man. I love your honesty. Things are not perfect all the time. We have to do what we have to do. I dont do a ton of refrigeration, but I would imagine its stressful, especially with call backs. I can see a customer saying, " you owe me for $500 dollars worth of product, because you were just here" and stuff like that. Again, great job man. You're officially my favorite you tube guy!

Awesome work and clear explanation I like it.

You do a fantastic job! I'm learning a lot from your videos. Thank you for sharing. Blessings

There is just soo much with refrigeration so always going through everything. Great video from a true mechanic! Just takes a lot of time n effort

Thanks a lot for your videos, I’ve learned soo many things from you, god bless you

Love your videos man, keep at it. Happy Friday 🤙

Man I really enjoy your videos! As techs it’s always nice to “rub elbows” with other techs and share knowledge. Iron sharpens iron!

Good stuff. As someone who has been in the HVAC/R service industry for 30 plus years, its refreshing to see someone who actually works on this crap and calls it what it is, Crap.

At the end of the vid, it's a clear example of theory textbook vs. real life practice. I'm a long time computer systems administrator. The same argument applies. As the on-site repair person, your knowledge of the principle of operation will always get you though the issue, and sometimes you got to color outside of the lines to make the magic happen.

No need to second guess or explain your work .We know that you do the best job possible. Thanks for the sharing of your knowledge.

Great video Keep them coming

We thank you for that video!

I worked in a restaurant back when I was in Engineering school. Refrigeration Techs keep our food safe. I'm cracking open a frosty cold beer with thanks to you and your amazing trade.

We are into hvac compressor business mainly reciprocating comp. Learning a lot from your videos.

Fantastic video 👍👍👍

Love your videos they are very informative and have taught me a lot thanks.

Really good job

You're the man bro I've said it before 👍 Keep up the good work brother you're a gem to the trade, thanks for the sharing

Good Vid Chris ! no, you're not a hack. you do above average repairs. some times awesome repairs , sometimes not. i live in the real world. you do the best u can do for the job that presents itself. Life is not perfect. 1) That Debris in the Drier is Compressor winding stuff. i'd put money on it. visit a compressor rebuilder and bring that stuff with you. they wrap the compressor windings in paper with lines on it,. rope wraps the windings together etc. varnish from windings. When compressors are coming apart they blow thier guts downstream into the driers. Thats why its allways a good idea to cut a drier open on a system with issues to see if compressor is comiing apart. 2) on that contactor replacement --- you broke 3 Golden Rules, thats why u got the rotation wrong way. 1) Allways take a picture of the Contactor wring with your phone or on a notepad. 2) double check wiring with your phone picture and / or notebook / or notes section on your phone. 3) in a rush from rain etc - very dangerous. dont do this. you have family. not worth it. no equiptment is worth it. put a pop up on the roof if u need to work in the rain or hot sun. take care of YOU FIRST ! YOu will live to fight another day. and repairs will be better. 3) the hole in the pipe spewing refrigerant --- thats the Classic - HOT WIRE SHORTED TO COPPER TUBE. blowing a hole in it . i just did one of those . one of the evap fan wires from the cover part rubbed/smashed aginst tube when u put the cover back on again. you did not show a repair on that one. wire hairs from wire nuts ?

When im pulling a vacuum on a older system, i have a good, better, best scale. 1000 microns is good, 750 is better, 500 is best. ill let it pull for about 30 min, and if its good, its good. I've completed plenty of jobs at just under 1000 microns without issue. Its the reality of the real world, you're the nth tech on that 20 year old system.

I think the best part of the video is the pressure control. Percussive maintenance. "I think it's stuck" "maybe not" *whack*.

18:17 Sticky pressure control -> Whac-A-Switch a new game for HVACR technicians!

Good job Chris

It amazes me how untidy all the cable routing is. Trunking is easy to use and would often stop and cable sheaths to rub through and short

Great video

Great video bud! I don’t have but a few racks, always fun to work on though.

Once again a brilliant job and video. I noticed the fusible plug on reciever F was more than half way out,( watch it at 0.38 sec ), definitely a refrigerant leak on that...as I've had them on jobs which are flush but still leaking...Javac D-tek is just the best.

Nice job

You should get yourself a quality megohm meter, you will be able to accurately test the insulation quality of the motor windings at first glance, which would save you time troubleshooting, and help you determine the integrity of motor winding insulation - near instant diagnosis of failed or failing compressor (or motor) windings. Imagine how much time you could save

WOW, what a mess! hope you can get that beast fixed and running correctly..

Biggggggg Job. And very instructive. Thank you very much god bless.

Brilliant video mate !! Had my fair few of cluster F's this week also !!

Not even close to being a hack bro your one of the good ones and I'm sure your customers appreciate that about you

It's good you show your screw ups! You are just like me. I have reversed compressor windings before. Lol

What a mess.This has been a very entertaining video

I agree, you will never get a great vacuum on a pumped down system. Great work bro.

I have been watching a lot of your videos recently. I have come to the conclusion you are part contortionist and squirrel the places you get in to :).

Thank you for another interesting video,, From work i have done in the past , i rate my self as an average AC engineer,, ,,, I had less experience in commercial refrigeration,, i rate commercial refrigeration deep freezers as one of the more difficult jobs in refrigeration/AC...Not easy to tackle multiple problems,,, and if there is a difficult customer who does not want to pay for a new compressor , then it becomes near impossible,,,, It takes years for someone to attain this lever of experience,, ...

Good job.!!

What a marathon. 👍

a good mechanic regardless of specialty has to improvise from what they are taught, I learned that in my 42 years of the working side of mechanical engineering

good stuff thanks

True. Excellent practices. It is what it is.

Wish all this stuff was out there in 2013. I really enjoy watching the struggles without having to live it.

I love this channel

in my 40 years never can prove what that shut is in driers but u must just deal with it sine of bad comp ur right oil is not the prob usally i love this shit

The black stuff might be burned oil from the overhead motor. Seen it before inside the discharge line right at the compressor. Also, low gas volume relative to capacity can produce high discharge temperatures. (Motor heat). Back in the day, the gazzilion pinhole from vinegar problem, purge the low side and charge it back up. No, you’re not a hack. If you cut the compressor open, look for marks from rotor/stator contact. The bottom bearing goes loose.

The bottle for the powerhead is a good idea, my journeyman gave me the idea to use a can of armaflex glue, but ive used a roll of electrical tape in a pinch with smaller cap tubes.

A scroll shell WILL be hot since its the high side, where a recip is suction. Thats why a scroll works so great in ice machines, all that heat saturated in comp shell durninng freeze cycle assists in harvest. 1st time I heard a scroll run back wards thought I had a DOA. Is there a "P" trap on suction, how much of a rise to cond unit? Take that evaporator on turn it up side down or switch suction and Liquid lines. You should have evap outlet on bottom for those long evap coils. If you dont take care of oil return problem u even risk an oil slug to compressor. Maybe install an oil separator to keep oil out of evap circuit. Use that 15% silver foss braze, good shitz.Your right about the oil flashing and keeping moisture out. Always put sight glass on OUTLET of filter drier. THAT much crap in drier was probably a restriction, was direr colder on outlet when running?. SPORLAN solid core for the win! Looks like you inherited a mess. Good luck. Hope you take my criticism as positive. I know its ez to sit her and and pick. Not so ez on the roof. Asked many times to make s poorly designed system run better than when it was installed. NOTE ABOUT EXPANSION VALVES; I have found over the years that if I am having TXV issues, or a unit that has a cond unit in high ambient that I install a BALANCE PORT valve. It reacts MUCH faster, adapts to changing loads better, reduces super heat hunting and increases system efficacy enough for a pay back in energy cost. ACID TEST THAT OIL!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I would even add a Sporlan HH, carbon packed suction drier. It will clean oil before it gets to compressor. The "BLACK" stuff that came out of drier will turn into a liquid (most of it) if u add refrigerant to it!!!!!!!

Chris, I would say YES, that black debris seems it came from Leak sealant, I have seen that in my experiences in the past. There might be other additives that was put in the system, check the oil from the compressor, and crankcase, for sediment. But I would say definitely it was from leak sealant. NOT GOOD STUFF, If you opened compressor, and check motor winding's, you would see a coating buildup , a good reason for the higher amperage. As for oil logged evaporator, if you on a pump down, run very hot water across the Evap, several times it will increase velocity, after boiling off refrigerant and may carry the oil back, depending on Suction line size ?? and travel of the line. Good luck, can't wait for the followup of this job.

I’ve had a scroll on a Protocol giving me problems for a week. kept going on overload. Amps okay-ish. I replaced DTC. Was flowing, not enough. Copeland says to check discharge line temp. Slowly overheats. Also the dirty filter, definitely carbon. Everything I do is Supermarket. And it’s old. It’s all dirty.

Missed the last part earlier, but that looks like its possibly enamel from the compressor windings. After the stator is wound most of the time the completed stator is dipped in enamel or some other encapsulant to keep the windings mechanically stable. It looks like it got so hot inside that it burned it all off. This would also explain the split in amperage since the insulation on the windings is probably compromised as well. But, its hard to tell from the vid what the actual texture is.

It makes me wonder if the Mitsubishi mini split systems are also subject to this problem of the compressor being under cooled/lubricated with only one station calling? It was very interesting to watch as the real world factors came into play instead of just here's tbe optimal practice and that is all.

I wondered if that stuff might not be fallout from the faulty compressor, possibly varnish that got hot and flaked off some of the motor windings. The way that thing was leaking, I'm amazed you were able to charge it faster than it was escaping!

Dude glad I’m not the only one. That has them tar baby calls. Good stuff.

Guess what I use to wrap my power heads back into a coil. 😂😂😂😂

Awesome!👍

Backwards compressor goes brrrrrrrt

Looked like carbon at first to me too...but those texture lines are very suspicious!.. Never used leak seal personally but herd lots of horror stories...also most techs dont pay attention to oil return most times...u did right tho...replace the usual suspects and work backwards...nice job chris....

Where there is way . I new that was good for thing. 👍

I think the black stuff is cupric (copper) oxide. The result of silver soldering with air on the tubing's inside, fixing many leaks. Ron W4BIN

With calcium build-up on the sight glass, there is so many different products on the market that dissolves calcium build-up, things like Lime-Away, CLR, etc.. Spray or wipe it on, wait a few minutes, should get rid of any build-up.

That stuff is FIX-A-FLAT .😎😎😎😎😎
