Your videos are great, I like how you look at the "big picture" every time. There are just a few occasions where you go for a "change everything" approach and don't isolate where the original problem was. A few customers would probably want a fix for that problem with an option to fix everything else. I'm not saying that's the right solution but if I came to fix one issue at a location and said it needed 10 things fixing/replacing (even if this is exactly what was needed), but one change would fix it immediately, there could be an issue. I think you guys must have a really loyal customer base to let you decide what does/doesn't need fixing on any job. Thanks for the content. 👍🏻👍🏻
Good one Chris. It was 98 on the roof this morning. Change out 3 freeze stats on 1 year old York units and then had to order a control board for the other. Someone hit the transformer pole and the board got fried when power company kicked power back on.
This is why I love Lennox, because they use those Sporlan TXV valves….where I can just change that powerhead, clean out the stuff that might be inside, and we’re back in business. I have a whole bucket full of new bodies that are going to go to the recycler for the brass.
That purge setup when brazing the filter drier in is so beautiful! Ohhhh mannn it's so beautiful! Thank you so much for being you Chris. I love it EDIT: OMG AND THEN THE REFER BALL VALVES FOR FUTURE DRIER CHANGES! OMG ITS SO BEAUTIFUL!!! 😭 IT MAKES ME SO HAPPY
I love the 80s music on the longer videos. I was in my garage last week working on my lawn mower had one of your 44 minute videos playing. The music started plying and it made my day. I am about the same age as you are.
I’ve seen that same thing happen on numerous Copeland compressors it’s never clear exactly what causes their failure. Your decision for no suction drier is well placed since the compressor likely instantly stopped and contamination stayed near the compressor. Side note: I always chuckle at the warning stickers those Lennox units have on the panels. “Remove screws before opening panel”. It makes me wonder what made someone feel the need to install them? Unless it was their way of using the same panels from screw on to handle latch. Love seeing someone do quality work across the country.
Honestly I think flushing would have been warranted on this one do to the back sludge you had, also nitro flushes close to nothing,it just blows it all on the walls of the tubing so just relying on dryers isn't great imho. Glad you ended up replacing the whole txv. Love the balls up and downstream of the dryers
Tbf the burn out looked titan sub sudden. The bad oil never had chance to be pumped around the system plus as it discharged up the system being off for a time the oil would have mostly drained down to the U bend Cutting it half way up showed little contamination travel so a blast out would have been sufficient. In the good old days a blast of liq R22 was the thing to do..times change..
Whenever I see a blown terminal, its always from high pressure, theyre soldered in to pop as a safety measure, I'm sure you know but that coil was covered, good call on the isolation valves and txv, nice work!🎉
Just did a geo thermo system this week that had a bad burnout. Acid test was instant. Used that same drier. . But we flushed the geo and the coil and lineset with Rx11 . And flushed it till they came clean. Down fall was we had to leave it pulled a vacuum overnight . But it was down to 110. And held. Love this thing I learned from your channel . Please keep it up.
I been working in refrigeration for a year and loving it. This type of videos motivate me to push my skill set to a higher level every day to be as bad ass and knowledge as you. Much respect 🫡 , hire me lol
Love love love that you use iso valves.....it makes life so much easier in the future. Thats some #bigpicture thinking Chris. You were spot on with your techniques. I do use acid scavenger and it works really well....many many years of using it and absolutely no failures. I do use suction line driers on bad burnouts....granted a lot of what i work on allows me to use cans and filter drier cores....so access is a lot easier than a typical drier. Awesome video as always Chris.....Definitely one of my top 3 channels i watch religiously....🤘🤘🤘🤘🔧🔌🎥🎧
I plan to be a HVAC repair man soon, these videos are for sure getting me ready for what I need to be ready for, that heat though, thank goodness I don't live in California, i could NOT take the heat! Great video like always, informative too.
Love your attention to detail. Even the little things, washing coils at an angle, cleaning up as you don’t need things so no wasted walks back and forth to the van. Keep it up 👍🏻 what do you use for a nitro regulator?
Our ac stopped working, texted my hvac cousin. But trying to explain why the coil need to be cleaned to dad. Because of your videos kinda understanding what might be wrong.
Really enjoyed this one. Got a question, with all that nastiness in the pipe do you need to replace the pressure switch? Keep making them and I’ll keep watching.
Just had a compressor blew out before the 4th as well after fixing the txv equalizer tube that snap off of the suction line, didn't realize the compressor was also grounded out until after fixing and BLAM! System was only like 3 years old. New compressor was installed by other tech and everything running again.
Love this video and I was wondering how you clean out your gauges at the end of a job like this? Thanks so much for the cool tips and I have learned so much (especially the electrical testing/troubleshooting) from your videos even though I am an industrial mechanic. Take care Chris
Nice video as always 👍, I would love to open that compressor to see the carnage. A burned out compressor is kind of the worst thing, all the resin and plastic on the windings turn to horrible things (they are gooey and corrosive). By the way nice vacuum setup 👍 Greetings Alex
i wish more people would explain to customers more often if you do not do prev maintenance, if will cost you more in the long run if things breakdown and harder to diagnose issues and fix and say I want to save you more money in maintenance repairs
Ahh, compressor terminal pin blowout. The failure to end all failures - you have a dead compressor, puked your gas charge to the environment, and depending on the age of the equipment, about as cheap to buy a new unit. I've only seen it once, but I got to see it happen. Compressor finally ate it during diagnostics, internal short blew the pin apart, my underwear almost didn't survive. 😂
Hey Chris. Someone probably already asked this, but you typically like to go with the flare type drier in refrigeration systems. I would think since you went with the trouble of inserting ball valves, you would have put in a flare type filter drier. Maybe they don't make them in the 163s HH? Probably...
Ugh freaking terminal stud blowouts. I've come across a few so far and one on a 3t condensor sadly was not blown completely out and was still sealed up...barely. It had individual wire terminals and not the terminal plug head and had burned the wire free of the R terminal connector. When I went to pull the burned up connector off the stud to ohm the comp and or put a new connector on the wire and hook it back up the stud pulled out with almost no effort and force applied. Imagine my immense surprise leaned over down into the top of the condensor with my head like 1 1/2' away from it when that stud popped out. I couldn't get out of that fog fast enough and sliced my elbow and arm pretty good on the fins and left a pretty good mashed groove in the fins. Was...not a good day to say the least and I was just a little hot to trot for a bit. I couldn't believe that stud was literally on the verge of falling out but was holding back something like 140psi of idle pressure and all it took to push it over was me barely pulling on it.
Ball valves & access fittings on just LL drier $$ just to isolate drier in case of another major failure.. How do your customers pay you? What kind of customers do you have?
Hey Chris you should open the filter dryer see what's inside? On the Bus transit side Thermo King recommends 3F of Delta degree temperature. What does Sporlan recommend?
With the wireless JobLink probes, do you still need to put low loss fitting on them even though they dont have hoses? Or do you have them on so you don't leak anything when you're hooking them on? If its the second case, do you have to purge them whenever you're working on a different refrigerant than the last time you used them?
I'm not sure if this has been asked/answered.... do you know you still have the factory film over your fieldpiece gauge set? if so, is that because you don't want the plastic "lens" getting all scratched up?... asking because I noticed the crease when you moved it @23:55 totally understandable if that's the case, love your content but man take it easy out there in the heat this summer.
i would be curious to clamp on an in-line fuel filter when purging trash out, with nitrogen, to capture contaminants so you can inspect when you remove the filter media. its standard practice in the race car industry to cut and inspect your filters for wear materials
I had no idea so cal had black widows. Here in northern MS they are all over the place this time of year. You really have to piss them off to get bitten as they save their venom for prey and they are timid. You can see videos of people handling them on youtube. Brown recluse spiders scare me more as they are aggressive and like to live in human spaces.
Forgive me, i just don't understand (2) things... 1. Why heat up a pipe to disassemble it? Why not just take a tubing cutter or similar cut instead of heating up all that old oil and causing issues when it's not needed plus MUCH MUCH cleaner to simply cut the pipe?!? 2. Why use couplers when a good swage tool is much cleaner, easier, and a solid (PIPE.PIPE) connection?!? Just curious..... Nice work, keep up the good stuff my HVAC Brother!
Instantly can hear the meme voice reading the video title. Also yay for brazing montage! Something odd about the panel hinges on the unit though. Were they replaced at some point?
When you have two circuits… how the heck do you know what circuit is what? I am deathly afraid of going to change out a compressor and cutting the dryer out downstream and just getting sprayed because I have the wrong circuit? I always loose it when I am looking.

Hands down....
That spider killed that compressor.
^.^
We'd have to know if the compressor was male or female.
It’s a shemale
@@ronaldmcdonald999 Not a futanari?
I was bitten by one that size. Ended up in the hospital. Was very sick for a almost a month.
Even though I’m not in HVAC I have taken a few points that you have made and applied it to my industrial maintenance job
Same. I feel like I’m a better technician in my field because of these videos.
Ditto. I’ve learned a lot of little things over time watching his videos.
Yea "big picture" really applies to everything.
Break down techs are a dime a dozen !
Customer: Why is my A/C not working ?
Chris: It ain't got no gas in it
That black widow looked amazing
Hell yea the 80’s brazing montage returns!

whats a freeze stat?
It is a safety sensor that opens up when temps are below 40 degrees. Kills power to condensor fans and blower I believe. Ithaca on a York 20 ton unit.
Ew Yuck equipment lol!

Best channel on TH-cam for thorough diagnosis and repair.
Like Eric likes to say, “well, there’s your problem, lady!”
Had a power surge at work today, and after things settled down, the breakroom AC sounded like a Dubstep Concert. That'll be a nice bill.
That purge setup when brazing the filter drier in is so beautiful! Ohhhh mannn it's so beautiful! Thank you so much for being you Chris. I love it

WELP TIME TO BINGE EVEYR VIDEO THIS GUY HAS FOR THE 8TH TIME
Really surprised you didn't use flared fittings for the dryer especially since you mentioned possibly changing it later
I think he can isolate the dryer using the ball valves. Then vac out that area using the Schrader port before releasing the charge.
Finally Epidemic sounds is back in hvacr channel 😅
I was hoping u would autopsy the compressor but I understand u have a big job pressure 😊
Honestly I think flushing would have been warranted on this one do to the back sludge you had, also nitro flushes close to nothing,it just blows it all on the walls of the tubing so just relying on dryers isn't great imho.

Tbf the burn out looked titan sub sudden. The bad oil never had chance to be pumped around the system plus as it discharged up the system being off for a time the oil would have mostly drained down to the U bend
Cutting it half way up showed little contamination travel so a blast out would have been sufficient. In the good old days a blast of liq R22 was the thing to do..times change..
Simply just trying to blow out contaminants using only nitrogen on such... Pretty much, only 11:33 a waste of nitrogen
The music! Takes me right back to playing with Casio keyboards in radio shack...
Whenever I see a blown terminal, its always from high pressure, theyre soldered in to pop as a safety measure, I'm sure you know but that coil was covered, good call on the isolation valves and txv, nice work!🎉

So Im at where you said... wonder what happened to that compressor ???
And Im like didn't you just washed that filty condenser😂😂😂😂
I guess with that air filter that dirty , system more likely froze up many times and damaged the compressor , maybe
Great Video. Thank you for sharing

Flush through with nitrogen then use denatured alcohol. That flushes the oils out.
Another awesome video
Good work Chris.👍
On things like valves, i like to use 60% silver solder, it melts at a lower temp, and flows better, then maybe crown it with silphos.
oh good lots of vids to come !! What the heck sounded like a washing/tumble dryer ?? on the roof .?
Nice video as always 👍, I would love to open that compressor to see the carnage.
A burned out compressor is kind of the worst thing, all the resin and plastic on the windings turn to horrible things (they are gooey and corrosive).
By the way nice vacuum setup 👍

Great job Chris. Thank you for the knowledge.

Wow! Close call. Could have been worse with respect to bodily damage. Wear safety glasses and clothes/gloves. Ticking time 💣
RX11 Flush is wonderful stuff. I use it all the time. No problems you flush it with nitrogen after you run the rx11 thru purge with lots of nitro.
What do you think about R141b for flushing? Is it good enough or are there better options?
Awesome video 🙌🙌👌👍😊🍀

Lmfao love the Simpsons thumbnail. Great job as always and great video!
we havent had an 80s brazing montage /interval for a while
@HVACR VIDEOS pls
Been in the habit of cutting the discharge U bend to get the nasty out.
Some people call it a Kaiser blade. I call it a sling blade.
Thay could have made sure that the new disconnect completely covered the old one.
Id love to see more on rebuilding the commercial txv's in the field. Is that an oem kit you order or some aftermarket universal thing?😮
For your torch what body do you use for your torch and what torch tips do you prefer?
F that black widow spider! Scary!
Ha I thought about that saying before with no gas in a ac funny
Haha...recovered to the atmosphere.

Great video I never use suction filters they don’t clean anything and chock return flow in my opinion
Do you think the EPA recommendations are wrong?
There no way I could let that spider live and work around there. That one was way too gnarly.
Do you ever use a product like Acid Away?

On a Lennox don't you charge or check charge via approach?
Ask refrigeration technology if they can bring to Italy viper wet rag and bigblu, there is no way for me to buy it here 😢
Every compressor install I do gets a new contactor

16:08 why is the tonnage different? 10 vs 5?
Why do AC compressors there have crank case heaters on them?
What vacuum setup is that?
I think the compressor terminal was born off due to factory default
Try recording in 30fps. We might see the board codes
It's my understanding that we need to hold the vacuum on these units below under 500 for 5 minutes on the decay test. What's your thoughts
I have a question on that measurequick is that a free app for techs?
Good intro funny stuff
4:36 Terminals!
how do you know if it was a compressor burnout? did you just assume the worst since you couldn't do an acid test?
I could smell the burnt oil. It was super strong
@@HVACRVIDEOS ahh I see. Thanks !
What would dielectric grease do for a contactor? help keep it clean and less prone to pitting or just simply a dust/sand magnet?
Would probably help in a more sealed contactor so it can't collect dust and sand, but it really seems like those contactors are just poor quality
@@dan4age Yeah true. but i suppose theres other reasons if no one ever does it. owell..
Attracts dust/debris leads to shorting out. Ok for closed terminal like trailer light plug; not Ok for open terminal
New subscriber. May I ask why was the TXV replaced? Is it just a standard procedure
Yes along with drier filter replacement
When you have two circuits… how the heck do you know what circuit is what? I am deathly afraid of going to change out a compressor and cutting the dryer out downstream and just getting sprayed because I have the wrong circuit? I always loose it when I am looking.
Run the good system and check for temp change on pipes
