Thanks bud! I am going to go live on UA-cam tonight 11/12/18 at 5:00PM pacific time to discuss my most recent uploads and answer questions. Come on over and check it out ua-cam.com/video/Fhmj8g3Gd2w/v-deo.html
Some people might laugh about bringing the radio, half your van, ice box, extra water, etc... but how much time / hassle is saved by not having to climb down and back up again with the stuff you forgot or needed? Work smarter, not harder! Love it!
All the people laughed at the office when I first suggested to put a shade on the roofs to work (Spain here, a LOT of sun) and OF COURSE reminded me that this is a wast of time. A waste of time to work a ton more comfortable? Taking 10m to get it mounted? Thank you for showing the right way to work. Taking the right time, not less, not more: the RIGHT time.
Ha the guys doing it in 4 hours, dont find the root cause, they come back in 2 months when another one fails and spend 4 hours again putting one in! You know the value of your work great job!
Fantastic Video and great job getting the compressor changed the correct way. Love the well thought out explanations and really like the wrap up commentary at the end. Keep the great content coming!
Love it when a dispatcher says “why 8hrs to change a compressor, so and so can do it 3-4hrs” and that’s when I say “ that’s why he has high call backs” you worry about your job, I’ll do mine. There is nothing worse than being rushed.
You have an excellent work ethic; once again, I applaud your well organized, and 'developed through experience' - systematic method. Being systematic cannot be instructed, it must be self-taught, and "to the beat of your own drum". In the '90s, my business partner and I learned to TIG braze (suction side, only) with silicon-bronze, and developed a heat sinking method for keeping the king valves from damage. We also repaired condenser coil 'runs' with the TIG, and had a method for removing, and reinstalling the condenser fins - to affect an easier repair. "Treat" yourself to working on a hot gas bypass system sometime (most were R-11 or R-12; and either Trane or Carrier (near Philly, at least).
I hate the burnouts, they take a lot of time and attention to get them right. The shade is smart, no need to cook on the roof while you’re working, helps keep you from getting heatstroke. 8 hours isn’t a bad call at all, there’s a lot of work involved getting the equipment up there, installed, and back down again. Good job.
Changed a compressor a while back, went back the next day and the oil level was over the top of the sight glass, drained the oil and it had three times the right amount!
I found your channel from Norcal Dave giving you a shout out, I enjoy your videos so much, you do a great job of explaining what you are doing and why you are doing it from start to finish, love the recap at the end...nice touch, You and Dave from Nor-Cal are great refrigeration Techs. Keep the great videos coming, Thanks again for sharing!
I'm not sure why, but I keep watching these videos for at least a month now, I like how you solve issues. Please consider having a go-pro mounting it on your helmet or something. it will ease up the filming process. keep up the good work!
I took a copeland course not to long ago and they said that 90% of compressors that go bad is from something in the system. Those guys that do the compressors in 4 hours don't investigate why the comp fails. 8 hours quoted everytime.
Yep! I took them as well and a lot of warranty compressors that are returned there is nothing wrong with actual compressor. 8hrs all day. You get what you pay for.
I 100% agree with your work ethic. Quote more time than needed then if you fish early thats great, charge them a bit less and they will be happy and call you back. Vs getting halfway through and having to charge them extra. Also i couldnt agree more with having some basic fire fighting stuff on hand. Nothing worse than when a small bit of flame catches something on fire in the unit then by the time you run to get water or whatever you got a whole issue on your hands where as if you had something next to you like a wet towel you could of put it out in seconds.
Years ago I was starting up a brand new carrier rtu with a bad burnout from factory. Changed compressor, added suction line drier, liquid line drier, purged system to get any bad oil I could out, pulled good vacuum, weighed in charge. Never seen that unit again after that. Would have liked to have gone back again to change driers. This was back in late 80s to early 90s.
Hello aleks, alone is 9 hrs with apprentice 6-7 hrs. If he doesn't want, tell him to do it himself and go work for someone who knows the trade... good luck!
Clean cmp[] change-out. Great video to let new tradesman learn right way to do the job. Just started watching your videos. Good job, very detail oriented. Aircooledtx~
Love the way you bid it 👍 God knows, when your boss gives you two other calls while your brazing in a compressor, accidents and mistakes happen more often, more potential for callbacks... Good deal, man
A lot of HVAC mechanics crack me up 4 hour compressor change up what kind of Kung fu ninja hack job would that be. I agree take your time, bid it right and do it right ! I enjoy the video thanks for sharing !
A lot of grounded compressors are caused by flooded starts. Refrigerant in the crankcase will show up as a high resistance ground, and can cause an arc at start up, especially if there is a little contamination in the system such as scale or copper flakes. Did you make sure the CCH is working OK? Also was that defective enthalpy control keeping the OSA damper open when it was not supposed to be, causing low return air temp? Most importantly, check for proper CFM over the coil, unit running with low load, etc. sometimes it is just a defective winding, just waiting for the right conditions to ground out.
I don’t remember if it was this video or of a Carrier which reminded me, but I had a highly contaminated circuit once. After two TXV’s clogging up, I started looking for a full Chatleff fitting. I never found one, but I found a Rheem part with both Female & Male Chafletts. I cut out the device, and used the Chatleffs which had 3/8” stubs on them. I sweated one for a new Chaflett TXV Inlet & I made the other side from 3/8” x 1/2” for the Outlet. I flared the existing EQ line, and used a flare union for the new TXV EQ line. A new Flare LLFD upstream (supported by a metal belly band), a new LL Ball Valve. The new (3rd replacement, 4th overall) TXV didn’t get plugged - but we were ready. I think we changed the LLFD once after this work was done. Sometimes you have to think outside the box.
Ignore what those idiots on Facebook say, every job and every situation is different. I’m in the Northeast and I couldn’t even work in those weather conditions
Great video man 👍🏼 Love it from start to finish. Great set-up as well. Wonder what caused it to ground. On a somewhat fairly new system. Have seen older units take a huge beating with many things wrong with them and compressor still purring along. Maybe just a lemon compressor? Who knows. You took great steps to assure the longevity of this one and customers investment. Great job! 👍🏼
I’ve changed out some very large compressors. One was a large carrier12 cylinder semi hermetic on a recip chiller. I believe around 125 ton. We had to warranty that change out, so there was a lot of extra time needed after it was up and running, to go back and check oil for acid etc. It’s hard to estimate how long the clean up will take, but it has to be done. This one required several oil changes and sets of driers before we were finally free of contamination. It was a very expensive changeout . Later that year, the discharge line exploded due to them letting the tower plug up, and bypassing the high pressure switch. Was one of my worst nightmares.
LOL, I wondered the same thing, saw this in the comments, and then noticed it was you. Small world sometimes! I see this was from a while back, but I only recently found this channel.
Top job Chris, that new customer seeing this repair should feel 100% he is in professional hands..i could just picture that Marat clown doing this job... that comp oil looked as black as the Ace of spades, in the past it may have done condensor fan motors/capacitors ??, and the comp cycled on hp ,or overload... comp got stinking hot.. i would like if comp manufactures put a stick on temp indicator on compressors.. if comp gets stinking hot it pops, or changes color.. That POE oil hates overheating, it breaks down big time...
Chris in the case of a burnt out compressor , should we always add a high acid suction drier with the new liquid line drier ? What are your thoughts on using an acid flush ?
Are you thinking the system is still contaminated? Do you plan to use the refrigerant again after you change the suction drier? Could you have flushed the evap with RX11 through the feeder tubes toward the evap outlet? Not being critical, just picking your brain, so to speak. I think you do good explanations. Hope you see it that way.
No worries bud, I appreciate you taking the time to watch my video and leave a comment. I went back a few days later and tested for acid and found none, but I had a 4 psi pressure drop across the suction drier. So I recovered and replaced both driers again. I didn't want to use rx11 in the evap because the liquid can get stuck in there and contaminate the system. I did however use it in the condneser.
With a burn out like that there are a couple things I would have done just a little different.I would have put in replaceable core driers and would have for sure added acid away.I would have come back on the Monday and replaced the cores and replaced the freon and added acid away again.To top it off I would come back a week later and pulled out the charge,pull out the suction drier and replaced the core in the liquid line drier or just replaced it with a standard drier.As I have always been trained...you should not leave a drier in the suction side,to easy for sludge to build up in the drier.
Hey chris I am getting ready to start the HVAC/R program at MT SAC in walnut and I was curious if you know that it will be possible to start working in the field while attending the classes or if I should focus on just the schooling and work part time at my current job, I am eager to get started in the field asap and it's a 2yr program
Tanner when i got started I went to night school and worked during the days, it was a difficult and it made for some long days but I got hands on experience while getting book experience. Send me a resume with your info i would love to talk to you some more!
Perhaps one of the phases to the compressor failed? I know for sure that a missing phase will kill any motor very quickly. I don't think there is any protection against that. Not after the contactor at least.
@@HVACRVIDEOS Interesting. Would that be due to contamination in the loop or just a defective part? Oil for sure doesn't look too healthy. I thought there is a low side limit switch to prevent such a situation.
There was a problem with the oil in these compressors from the factory and it caused a bunch of failed txv's it happened to a bunch of these units on the roof.
@@HVACRVIDEOS Yes I remember an issue with the Copeland scrolls where they were using anti corrosive in the oil that was killing TXVs and in turn compressors if I remember this correctly. I am wondering what your take is on Daiken equipment? The company I work for is primarily residential but we sometimes do some commercial stuff as long as it isn't massive. We just recently started to install the Daiken stuff and I would love to see what others in the trade think about it.
Great Video man. The other day, I got drenched in the rain on the roof working on a condenser fan motor with a beach umbrella just over the equipment only. I gotta get one of those EZ ups. How do you know the compressor was running backwards?
Yes makes horrendous sound and if gauges are on looks like they equalized because of running backwards.Once you hear the noise it's no second guessing it's running backwards
i never know that changing compressor is taking that long.. when I watched your video I was thinking, changing ccompressor is like an hour job. well, undo the lines, unbolt the compressor, plug the new one, bolt that down, sweat the lines, pump the refrigerant and done XD but, I'm horribly wrong...
I used to work for Lennox. One of the techs showed me this trick: sanding things such as the the suction and discharge ports on the compressor and lines sets with brush wheels (brass) like these: 0.25-in Wire Brush Wheel www.lowes.com/pd/0.25-in-Wire-Brush-Wheel/1000213189. Saves a lot of time and effort (working smarter not harder). I would also use hand brushes to sand inside pipes and filter driers, but you have to make sure you can remove the shavings obviously. I recommend trying it, you’ll love it.
Thanks bud I will look into those! thanks for watching I'm gonna go live this evening 4/29/19 at 5PM (west coast time) to discuss my most recent uploads and answer questions from emails, the UA-cam comments and the chat come on over and check it out . ua-cam.com/users/HVACRVIDEOSlive
Thanks for the invite and I apologize for not seeing it sooner, but I was having dinner with the family for my birthday. Definitely appreciate your channel and your help. I’m fairly new to the trade (in my third year after trade school). I hope to be able to catch the next one.
Thanks for watching I will be going live on UA-cam this evening 4/1/19 @ 5:PM (west coast) to discuss my most recent uploads announce the Sporlan Bq TEV kit winner and answer questions come on over if you can ua-cam.com/video/WLQxwzT65SU/v-deo.html
I actually didn't use the acid away, I left it in there in case I found acid when I returned to replace the driers. But I would have used it had the driers not removed the acid. I've used it many times and never had a problem. I do realize it is a foreign chemical and not really made for the system. But sometimes you gotta do what ya gotta do. Thanks for watching and taking the time to leave a comment!
Yeah even the crappy York units have some of those controls in them. I'm sure you can spec them in the lennox units but most of the ones I come across dont have any voltage safeties
Rennis Henry LENNOX inducer motors are 208 single phase. They have a transformer dedicated for it. No fuses either. So when your transformer blows it takes your inducer with it lol.
This guy doesn't mess around, sun blind, cooler, radio, then goes above and beyond. I love it. Smart tradesman.

Thank you for showing the right way to work. Taking the right time, not less, not more: the RIGHT time.
Thanks bud, yeah it makes a world of difference using the sun shade.
You just brought up the most important phrase of tradesmen! Work smarter not harder.
I’ve been doing commercial refrigeration amd restaurant work for 20 years. Love these videos. Always learning. I appreciate these videos so much
Ha the guys doing it in 4 hours, dont find the root cause, they come back in 2 months when another one fails and spend 4 hours again putting one in! You know the value of your work great job!

Comprehensive as usual . The extra effort to make yourself comfortable is well worth it . The environment in a/c work can be harsh .
Love it when a dispatcher says “why 8hrs to change a compressor, so and so can do it 3-4hrs” and that’s when I say “ that’s why he has high call backs” you worry about your job, I’ll do mine.
There is nothing worse than being rushed.
I like your thinking rushing leads to mistakes and usually frustrations.
Ain't that the truth!

thanks for the nice words and thanks for watching again!
I agree with you on that four hour. I’m not killing myself
Same here, thanks for watching!
Digging the 'wrap up' segment on the end of your vids, keep em coming!
Thanks and will do

Yep! I took them as well and a lot of warranty compressors that are returned there is nothing wrong with actual compressor. 8hrs all day. You get what you pay for.
Watching all your videos, you are the best, thank you for sharing your thoughts and experience, god bless you
Would love to see this failed compressor dissected, would be nice to see overall wear and tear on those scrolls.
I 100% agree with your work ethic. Quote more time than needed then if you fish early thats great, charge them a bit less and they will be happy and call you back.

Excellent job. Very true about not rushing through a job!
Thanks bud!
Yeah bro no need to rush a compressor job in the heat. That kills you at the end of the day. Take pride in your work and do it right. Good video
thanks bud!
I really love the umbrella setup. It is magic on a white roof.
Yeah it definitely helps
Great videos! I love learning how to do things the right way. Your videos are a great help!
Thanks bud
man i wish to work for a guy like you. My boss bids 1 guy 4 hours for an AC compressor and starts calling after 3 asking me whats the deal
Hello aleks, alone is 9 hrs with apprentice 6-7 hrs. If he doesn't want, tell him to do it himself and go work for someone who knows the trade... good luck!

Good thing I'm the boss so I decide when I leave! :-) thanks for watching bud!!!!
HVACR VIDEOS; Absolutely! Do you bid that much time for your guys?
Yep
HVACR VIDEOS; Figured you would! Good man! I didn't mean that in a challenging way, FYI... That's good ethic 👍
no worries, thanks for watching!
A lot of HVAC mechanics crack me up 4 hour compressor change up what kind of Kung fu ninja hack job would that be. I agree take your time, bid it right and do it right ! I enjoy the video thanks for sharing !
Thanks for the nice words! And thanks for watching!
lmao amen
Kung fu😂😂😂
Great video as always Chris, thanks for sharing
Thanks for watching again!
Nice work! Nasty burnout tho she will take a bit to clean
Chris strikes again. Good stuff bro!!!👏👏💪💪👌👌
thanks Ralph!
I heard that 4 hr compressor change alot and those the ones i get callbacks for , cuz most guys rush to make that 4hrs and miss small things.
You the man brother I like the way you work that’s a clean job nice 👍

Wow that's crazy
What's the stuff you were using to protect the compressor while you brazed it in?
LOL, I wondered the same thing, saw this in the comments, and then noticed it was you. Small world sometimes! I see this was from a while back, but I only recently found this channel.
It was viper wet rag by refrigeration Technologies
Thanks for the post and the tips
Step by step sir.. nice 1
Great job. As always.
Thanks bud!
Great video as always!
Nice job,great attitude...
Thanks!
Top job Chris, that new customer seeing this repair should feel 100% he is in professional hands..i could just picture that Marat clown doing this job... that comp oil looked as black as the Ace of spades, in the past it may have done condensor fan motors/capacitors ??, and the comp cycled on hp ,or overload... comp got stinking hot.. i would like if comp manufactures put a stick on temp indicator on compressors.. if comp gets stinking hot it pops, or changes color.. That POE oil hates overheating, it breaks down big time...
Yeah who knows what caused it, i did everything I could to try and find out. That's why I changed the txv, just out of precaution!
Wish I can work with someone like u here in NY
@HVACR VIDEOS Great job love the channel
Thanks bud
HVACR VIDEOS anytime do you run into any semi hermetic compressors in my neck of the woods I work on them all day every day
I used to run into them often but lately it's all scrolls. I liked the semi hermetic ones better
HVACR VIDEOS exactly tough as nails I'm in Chicago there are tons of them still kicking
Chris in the case of a burnt out compressor , should we always add a high acid suction drier with the new liquid line drier ? What are your thoughts on using an acid flush ?
Nice job, do it once & do it the right way.
thanks!
Hell ya Hotel California is my favorite song .
Are you thinking the system is still contaminated? Do you plan to use the refrigerant again after you change the suction drier? Could you have flushed the evap with RX11 through the feeder tubes toward the evap outlet? Not being critical, just picking your brain, so to speak. I think you do good explanations. Hope you see it that way.
No worries bud, I appreciate you taking the time to watch my video and leave a comment. I went back a few days later and tested for acid and found none, but I had a 4 psi pressure drop across the suction drier. So I recovered and replaced both driers again. I didn't want to use rx11 in the evap because the liquid can get stuck in there and contaminate the system. I did however use it in the condneser.
I will remove it if it has a pressure drop more than two psi, but if it stays at 2 psi I'll just leave it in.
Jim I have never heard of a bypass type filter drier, I will do some research on that, maybe it's something I just simply dont know about.
With a burn out like that there are a couple things I would have done just a little different.I would have put in replaceable core driers and would have for sure added acid away.I would have come back on the Monday and replaced the cores and replaced the freon and added acid away again.To top it off I would come back a week later and pulled out the charge,pull out the suction drier and replaced the core in the liquid line drier or just replaced it with a standard drier.As I have always been trained...you should not leave a drier in the suction side,to easy for sludge to build up in the drier.
with all that work back and forth hope u charge 3k for labor.
You bid it correctly 8 hours do it right won' t be back. You watch it run good on you

Hey chris I am getting ready to start the HVAC/R program at MT SAC in walnut and I was curious if you know that it will be possible to start working in the field while attending the classes or if I should focus on just the schooling and work part time at my current job, I am eager to get started in the field asap and it's a 2yr program

but, I'm horribly wrong...
When you replace the compressor is it already full of oil or do you have to put it in manually before you fit it ?
It's already full
Out of curiosity, how many minutes of torch time would you say you get out of those oxy-acetylene tanks?
Commercial units have filter drier on both suction and liquid line?
I look for signs too. What was that black crap on the door to the compressor area?
That was the oil from the compressor, when it grounded it blew the terminals out and vented the charge.
I have used R11 on bad burn gas smelled like rotten eggs. Very low temp unit cascade system.
I used to work for Lennox. One of the techs showed me this trick: sanding things such as the the suction and discharge ports on the compressor and lines sets with brush wheels (brass) like these: 0.25-in Wire Brush Wheel www.lowes.com/pd/0.25-in-Wire-Brush-Wheel/1000213189.

Video request. Show how you have evolved your refrigeration logging. Do you use an app?
are you asking how I track my refrigerant usage and disposal?
Was this a two stage compressor? The other day i had to change a thermostat, it was not sending the signal for 2nd stage.
No this was a single stage
👍🏻👍🏻👍🏻
Great job $$$$$
Thanks bud
I like to make sure all js good at the supplier. Its not brain surgery. Its a five ton
Thanks for watching I will be going live on UA-cam this evening 4/1/19 @ 5:PM (west coast) to discuss my most recent uploads announce the Sporlan Bq TEV kit winner and answer questions come on over if you can ua-cam.com/video/WLQxwzT65SU/v-deo.html
What’s kind tip do you use for your torch
Usually I braze with a #2 tip but in this video it is a rosebud #15 multiport tip.
is that a tecumseh compressor
Can you not put acid away in the new oil? Its made by rectorseal. Great content though 👍
I actually didn't use the acid away, I left it in there in case I found acid when I returned to replace the driers. But I would have used it had the driers not removed the acid. I've used it many times and never had a problem. I do realize it is a foreign chemical and not really made for the system. But sometimes you gotta do what ya gotta do. Thanks for watching and taking the time to leave a comment!
I use acid neutralizer in every compressor change out. It’s one of the very few additives approved.
Just cheap insurance.
Nice video, fase balance, and or eighter voltage drop?
Didn't measure anything abnormal, I think it was the txv that caused it. I changed it out of precaution.
I would guess that units electronics has voltage and phase failure protection in it... we don't get Lennox units like that in Aust..
It actually does not have any voltage safety's, go figure it has every other safety but those ones
Thats strange, its sort of been a standard for the past 15 years in alot of other units..
Yeah even the crappy York units have some of those controls in them. I'm sure you can spec them in the lennox units but most of the ones I come across dont have any voltage safeties
👍👍👍
thanks for watching!
I wonder why that inducer has a capaitor
Rennis Henry LENNOX inducer motors are 208 single phase. They have a transformer dedicated for it. No fuses either. So when your transformer blows it takes your inducer with it lol.
Because it's a single phase motor.
The drip leg is installed incorrectly. For safety you should never stand up the nitrogen tank leave it laying down until you’re using it.
Instead of replacing the entire txv, why not replace the power head? That’s the part that fails.
I wiggle wiggle too
you don't like the flush kit
Pretty basic repair. A lot of purging. don't need the commentary at the end of video ...….
