- This unit is really dying a slow death, with the lack of preventive maintenance and the fact that it lives in the desert its just hurting. But I did my best to get it going again but for how long I don't know.....

I got some Louis Rossman vibes from the intro.
You weren't the only one!
NO PLEASE !!!!
Heh, I watch him, too
When tech repair an hvac collid
darkknight01311 Louis is just becoming bitter.
I use a impact and only strip out 6 of every 10 screws, but 2 are on purpose so I have a challenge next time!
Those screws are easy to remove. Just get a small pry bar behind it apply pressure and zip it out.
I love my impacts 😍
Just keep rotating these screws long enough and they will fall right out ... :]
Weld'm together enough friction just keep spinning 😆😆
I use an impact on wood screws and thread-rolling screws and a drill on machine screws. I have a feel for my impact driver and only use it for high torque requirements.
As a ‘computer dude’ some days of the week I tell myself ‘if this doesn’t work I’m gonna quit my job and become a HVACR dude’
Tim G I would love to be an HVAC guy the problem is I’m too much of a pussy when it comes to temperature extremes. You’re either always freezing your balls off or burning your balls off. I’ll just stick to running my business which is in the dental repair industry. I’ve been doing it for over 20 years so why change now
Agreed, working in IT for the last 15 years I'd love to do something different. I mean I've always had an interest in Agriculture, I did that for a summer and loved it but there are not many jobs available in the UK for someone with not a great deal of experience, not many people are willing to train someone with limited knowledge since it may not be a stable investment.
Tim G seriously? It’s hard, dirty work. I’m good at it, as a maintenance man I’ve done pretty much everything but I hate high voltage. I let the electrician handle anything over 120. I got a handful of 277 once up in a ceiling changing ballast for warehouse lights, I said yep, no more of that, especially for the chump change places want to pay you.
postersm 71 you need any help? I’m tired of maintenance
Deborah chesser maybe, I don’t know what your background is. Let me know. I do everything in the dental office from x-ray machines to lasers from dental chairs to air compressors and vacuum pumps. That’s the kind of service/repair that I provide
Dirty coils lead to high discharge pressure leads to high temperatures leads to oil breaking down leads to plugged driers and metering devices.
Rewired(eliminated) variable demand exhaust leads to exhaust drives rewired for full speed motors and insufficient(nonexistent) make-up air unit leads to 100% open package unit dampers and open economizers which leads to excess air flow over condensers plus lack of increased pm is what leads to dirty condensers.
Exactly my thoughts. High temp and preasure breaking down the oil. May want to do an oil change cause if its on the TXV and plugged the drier, the sump of the compressor is full of it. He may wait till the compressor fails.
Which leads to the dark side.
@@SethMaelstrom thats liberal arts . This is the tippity top of the slave pyramid. Not the trader pyramid
And a headache for the service man!
That intro had me rolling
Same
Likes = same on main comment
SAAAAAAME! :rofl:
judging by that intro somebody is stripping screws lol.
I've been a hvac/r tech for 24 year's, I never thought I'd find myself watching someone make videos of his work. Thanks
Ha thanks bud
@@HVACRVIDEOS hey dude, have you run into any Hobart technician's out in the field.
Imagine where you'd be at if channels like this (or even UA-cam for that matter) existed 24 years ago. Watching this channel for me is like a walk down memory lane.
@@mc-sp8zr or gives high school students and pre tech students ,lesson before taking a course, man I’m in my 30s, so many wrong choices...if these technical videos exist when I was in high school I would have forced my self to take the advanced math and sciences, so I could properly take a trade course .. Worst still even as adult they would still require me to update math and science before looking at a trade course , 1 ..big lesson do not let schools push kids threw , or they will not have skills to properly exceed.
I used to spend hours hand cleaning oiled up old condensers. It's just frustrating going to jobs other companies "used to service".
Why can't my boss explain things like you. Everyone needs a leader like you. The more one knows the better he does in life. :)
And also when you work with someone that's "at a high level" you will more than likely get to their level if they teach you. I wish I could be Chris's apprentice lol.
The variable trigger on my 1/4 impact works perfectly. Not every fastener needs ugga duggas.
I'm planning to buy one of those, but I know my way around a trigger and i use an impact drill. I have never stripped any screws
mine has a switch on it so you can choose.
The 12v Milwaukee impact is the perfect size for tossing in a service bag to remove panels. Trigger and speed switch keep you from stripping anything.
@@em1osmurf it switches between standard drill and rotary impact function? i can't find those types anywhere i think i'm looking for the wrong thing. what do you have? thanks
@@cliveramsbotty6077 the m12 fuel impact i use at work has a sheet metal setting which stops once its tight
I've done a lot in automotive AC, done a lot of reading. What I find over and over again when I watch your videos, almost no one in Automotive really understands how AC systems work. I have learned more from watching your videos meant for other HVAC techs who already know the basics than I have from schooling, ASE Master techs, ASE AC books, and ASE master trainers. What I have learned from watching your videos has cut down AC diagnostics times and wrong parts replacements substantially. A job that normally takes me 3 hours to diagnose is done in 20 minutes sometimes because you have taught me about temperature and pressure differentials without having test ports all over the place and just going by line temps. In a couple of your videos you covered operational theory of some of the more complex components, which perfectly covers the simplified versions used in automotive.
If you ever get sick of restaurant HVAC work, you might try your hand at automotive AC, you'd likely be better than 95% of the guys out there doing AC on them. You'll just have to learn to fight around interior panels. Awesome videos!
I have no idea what you're doing, but as an engineer, I can't look away.
I know, right? Why is this entertaining and cathartic?
As a mechanic we thank engineers for jobs.
Funny you'd say that about becoming a "computer guy". I was in IT for years, went and trained on HVAC/R after a long employment dry spell. Had a blast in class. Thought I'd love being in the field. Never found a really good company to work for. Now I'm back in IT!
I'm sure impact tools have a purpose beyond making the use of a tire iron a larger source of grief than it already is, but I don't know what that purpose is.
I worked in HVAC for 30 years and worked for a dozen or more companies and a half dozen facility jobs. Only found one company I enjoyed working for. had to leave due to family health issues. there are no Good HVAC companies.
Really liked and appreciated your "post mortem" on the replaced parts. Validated your txv suspicions and educated newer techs. Also liked the comments at the end. Keep it up!
I don't know why I started watching these videos but here I am. Well done sir for making HVAC repair interesting.
Buildings should be slightly positive pressure, never negative otherwise you're drawing in outside air through doors and cracks etc. The air in the building is no longer cleaned by the filters in the air handlers. There is dust in the air and in the food.. Everywhere.
yep, always positive pressure, which also keeps sewage gas out of a trap primer quits working and they dry out
@RuleofVicus Reminds me of when they would start up the swamp coolers at Ft. Bliss, TX... the building smelled like fish for a week.
On the flip side, if you over pressurize you’ll get stacking, and your doors won’t close all the way. They had me on a ladder, stairwell after stairwell, adjusting door closers. 🙄 instead of adjusting air flow. Cooling towers, 250 ton chillers, air handlers, VFD’s. I’ve done it. Still would if my old body could keep up.
High-quality video. It substantially deals with the salient most relevant concerns. It is well-edited leaving no gaps in the well-packed content. There is no wasted time. I will be a supporter and I will return for more. Thanks, Sir. You are very professional having created and provided this video.
recently graduated from HVACR trade school. ive watched a few of your videos and while its a bit overwhelming because i dont have the experience.. its been a big help trying to understand the bigger picture. Great stuff man keep up the good work.
You have more than "a little bit of knowledge" to share! There should be about 2 or 3 thousand of you's across the country! Keep up the great work, and be safe.
"IT'S DYING A SLOW DEATH", aren't we all...
Mlirt try rf
So is my car
Blitzz This unit might have Condenser Coil Virus !
No! Everyday is a change to be young again and thrive. :)
A long life is the slowest death of them all.
30:08 I love the start up sounds of these A/Cs
I was told years ago when they started to recoup freon that it would be clean and used again. You are the first one to see cleaning R22. What my job do is we would clean and reuse oil. It is tested for acid and it is filter and dried out from moisture.
Thank you for taking the time for filming what you do. It helps so much. I want to get vetter on wiring, but it will come with time.
Thanks for the detailed look. It's great to hear a knowledgeable person go through the process of diagnostics, and follow up with the backstory. Fascinating about the smart vent hood system, as well.
Something so satisfying about cleaning coils, you just know it relieves the whole system.
Bro that intro lol we all get that way some days....btw picked up one of your shirts very nice! keep up the good work man great content for a non HVAC guy.
Thanks so so much for the support!!!
Dude that intro had me rolling man :) another great video, looks like they keep you busy huh
just happened across this dude! your humble and know your stuff! nice to see a problem solver not just a parts changer...im a self-employed gen contractor and i pride myself on telling the customer why, most all of them appreciate it even if they don’t fully understand. Im not an hvac guy but people like us never have the drive to keep learning. keep doing u and all will be great! paul bryant from south MS
I'm getting a leg up on the apprenticeship class learning the way I like to. I watch a professional till I become one. Thanks for the content 🙏
Chris, this is some next-level stuff, even for you. You are getting even better.
Clogged drier is interesting. We have an account where return air is typically high 80’s to mid 90’s.
Since your unit is pulling in 100% outside air I imagine it is similar heat load, since I am in East Alabama and have super high humidity all year.
Those units had issues with filter driers due to high superheat from heavy load on evap leading to poor compressor cooling. Oil breakdown and premature wear to compressor. We put in 30 cubic inch driers and still change half a dozen each year.
Ac stopped working today decided to go up and inspect and did a little checking around like you do lol figured out the 250 volt fuse going to the condenser fan was blown. Thanks man your awesome
Great video,especially cutting open the drier and disassembling the TXV . Love the detail and explanation of procedures.
Quiero felicitarte por tu excelente experiencia y paciencia para encontrar los verdaderos problemas que se presentan en los equipos que tienes que revisar y reparar, además lo grandioso que es aprender contigo. Sinceramente muchas felicidades y muchas gracias por todo tú tiempo y enseñanzas. Saludos a todo el equipo desde Coacalco Edo de México.
I told my dad I was watching a man fix an ac and he thought I was crazy!!! Great channel super interesting thanks UA-cam recommendations :) 🇨🇦
The salt is palpable from the very first clip and I LOVE IT. Keep it up chief, much love from a Michigan nurse
Great work Chris. What I've always loved about your videos is you give a lot of really helpful tips in them. I shall not race through the rinsing process again lol! You also speak as your talking to an apprentice in person which is helpful, it sinks in more lol.
Appreciate the autopsy of the drier! Thank you. I enjoy your videos and have learned a great deal. Your are a good teacher ! NJ
Excellent video as always sir. I’ve been into this same issues with metering and drier. I found issue was damaged piston compressor that have shaved pieces it will clog drier up and metering as well. Maybe one or two months later the compressor is grounded. And scroll compressor just replaced drier and runs good, depend on diagnosis. Again I’m impressed that you’re right on spot sir.
Solid job. Was very nice to watch you work. Big thumbs up.
Watching you do all this stuff is just therapeutic
I have only recently started watching your videos... wish I knew about you when I was in school for HVAC... I legit stop the video and try to play out what it could be.
I work maintenance in a hospital and run into craziness that has nothing to do with our HVAC units. Your videos definitely keep me on my game when it comes to AC repair!!
Thank you for these!
As a Floridian where AC is essential your channel is super interesting and ultimately useful so I can learn how to diagnose my own problems and fix within reason. If I can't fix it at least I can save my HVAC guys a lot of time figuring out the problem!
Finally, someone who know wtf they’re doing and does it right. Good shit bro!
I away's Learn when I watch you're videos ! Love it keep it up brother !
Who knew watching some random UA-camr fixing air conditioners would be so satisfying to watch! Subscribed
At 07:30 did anybody else close one eye, and move their head from left to right, to check if the pulley was straight? It doesn't work on a video screen...
I've done that in games trying to look around corners or bushes. You catch yourself doing it and take a moment to contemplate your brain fart.
Yep... It's involuntary...
one hand on either side of monitor, oscillate...
Doesn’t work on some people’s eyes as well from what I’ve had to rectify
@@EnderMalcolm i do that in games a lot but i also automatically look around the corner ingame so just for the immersion
That was a hilarious drill pun ! Got to love those coil cleaning so call techs ! you can see the spray lines . You wonder if they even used water . Nice job !
Dude ; Couldn't wait for this to come online; as always great video..you are the best at this...Thank you Chris.Always waiting for the next job...
I enjoy the troubleshooting aspect of your videos. Especially useful is "look at the big picture"
awsome to see some of the work im in for when i finish learning home airconditioning
One of the best vids you've made yet! Thanks for doing what you do G.
That intro was the best... When i was an instructor i would teach that to all my students based on my years of experience with striped screws especially on carrier units. Simple yet , most do not care... I have bought thicker screws and replaced thousands of stripped screws over the years...Mechanics 101.
Yup!
If you're going to use a screw-gun to install machine screws, either:
1) Get REALLY good with trigger-control (not recommended)...
2) Use the screw-guns clutch properly (semi-recommended due to people getting lazy or forgetting to set the bloody clutch)...
Or
3) Use the screw-gun to drive the screw in almost all the way and use a screw driver to snug it up (also semi-recommended due to people getting lazy and not stopping before they've snugged the screw down with the screw-gun and stripped the threads)...
When I was in Electrical Trade School, if an Instructor (didn't have to be your Instructor) saw you use a screw-gun to install a switch or receptacle into a device box, you automatically fail that Practical Exercise right then and there...the School reused the switches, receptacles and device boxes for as long as possible to save on costs and they were replacing too many boxes due to stripped screw holes due to screw-guns being used on them so they implemented the Screw-gun=Auto Fail policy...
It worked, the number of stripped screw holes dropped immediately after the students got it through their heads that the Instructors/School were NOT kidding about it...
We have very similar issues with "removing the hood system and not having a make up air unit, with the added benefit of high humidity... Thanks for the vid
I work on all types of A/C systems from vehicle to commercial. Recently I had an interesting one on my Jaguar. It just suddenly quit working while driving and come to find out the desiccant bag suddenly disintegrated and plugged the drier filter. Thankfully it is a very well designed system that has a very fine micron filter and has enough capacity from the compressor to drier that it never came close to over pressure. The rest of the system was spotlessly clean. Can't complain after 25 years of use
the best thing that happened today, was getting HVACR video, video notification.
Wow, the companies who make this stuff have literally zero pride in their wiring. This was pretty interesting, it’s a lot more complicated than I’d expected. It would drive me nuts having to deal with other workers sloppy maintenance though. Nice video, you clearly have a lot of experience.
i learn more here than when
i went to school or maybe
i have basic understanding
already ... it's a win win
situation on me thanks
Great video! Always learning!
You’re pretty good dude. Glad I found this channel. Experienced techs in the comment section as well. Good shit
Always a pleasure to watch stuff like this 🤩
Nice to see you used a drier when recovering the refrigerant. Also I was screaming at my phone for you to check that dryer on your 1st visit but I suppose as long as you carry spares for when you did the expansion valve, its ok.
Thanks for another great video Chris!
what neat toys you have! i remember my electrician helping the MMs carry in 5 gal buckets full of hoses and gauges. something that size would have taken a week at least to troubleshoot. bluetooth. amazing.
" Remember big picture" is a true mentality thanks bro for your videos.
Great video, lots of info! Thanks.
Nice to see someone knows what they're doing. Great job
Really like this video , understanding the failure of the dryer/txv due to the outside air . When it comes to replacement you should recommend a DOAS
Dick on a stick?
impacts are great, the knowledge of how to get the tool to do the job intended is priceless..the newer milwaukee impact i own has the option to cut off holding on the first hammer strike or even set the torque very low and is the appropriate tool on fasteners instead of using a drill made to drill holes mutch like using duct tape to seal ductwork...
Great video! I agree with your diagnosis. Dirty condenser, and evap running far warmer than normal due to 100% outside air, must have had compressor discharge temps going sky high. With mineral oil, that's gonna cook it, and it then leaves wax deposits everywhere, especially in any already occurring reduction in the system, such as the TXV orifice and the multiple passages in the drier.
You're fortunate that Lennox didn't use a multi-orifice metering manifold like some Trane Voyagers do...those are a nightmare with a similar poor operating condition (high head pressure; high superheat/poor compressor cooling) when those orifices plug up with overheated oil wax.
lol! That intro was awesome. I love the 12v Milwaukee electric screwdriver for taking off panels. Beats the drill and impacts by a long shot.
24:47 nice see thur filters i like that
*it give everyone idea what it looks like inside it*
It is amazing how many people don't know how to use or adjust the clutch on a drill. If you are doing a ton of screws it can be a big help to prevent stripping or over sinking things.
You almost couldn’t sell me a drill without a clutch.
Oh, I have seen the desiccant come out of the drier and fill the liquid line after it. Thank goodness only twice in 35 years. One was on a package unit and it was easy to throw away the old liquid line. The second was a split system with about a 25 foot length on a walk in and at about 600 psi nitrogen it shot across the roof!
And another case of pressure limiting TXV's.
Love those new Malco bits. They come with a price tag but they are worth every penny
Another great and informative video, You ROCK Dude!
I use a 12v Milwaukee surge impact on all commercial stuff. Setting 2 never strips anything. Can count how many carrier and icg unit I see that have stripped screws. Same thing with York. It’s the bane of a commercial techs existence.
Keep up the awesome work and thanks for the content stay safe and take care
As a former carpenter and current HVAC technician can I offer some advice. Drills are for twist drills to bore holes in things. An IMPACT is for sinking and removing screws (fastening device). That being said you are correct about it being about trigger control.🇺🇸
0:09 I'm not throwing away my impact drill. Then again, I work on engines & not A/C units.
Is that the broadcast interruption man on ur profile image????
@@Abhishek-C92 Yes-es-es
Catch the wave!
I have actually seen a drier fail on a R-134A system and filled the liquid line full of desiccant beads. They were packed so tight I couldn't get nitrogen to flow past or back purge them out. First and only time I have seen this.
Intro. Exactly! Thank you!
I have no idea what your talking about but you make it interesting to watch.
The kind of stuff this guy is saying can only come from experience. This video makes a good tutorial.
You are the best and make the best work and videos
Thank you my man
I like the belt pulley tip. A lot of nuggets to hold on to in this one.
All that wireless equipment is amazing. I love it. I don't do this kind of work but I've been around it.

Very interesting history. Great big picture explanation!
You Sir, are a credit to the industry. Subscribed.
You do very good work bro 👍 and have saved that poor unit and gave her more life
Love your videos I fix computers and reflow mother boards and solder all day.
I like how you take the time to explain all of the details of what's going on. It's obvious you take your job seriously and these day's it seems that some people will do the bare minimum just to get to the next job. In those situations if it blows cold then it's fixed regardless of other maintenance issues that are present. My experience is in automotive A/C but I've learned a lot from your videos about commercial applications. I haven't seen all of your videos, but do you also work on chillers for large offices or skyscrapers too?
I am impressed by the automatic censor/PPI filtering on the UPC code.
I've seen too many videos that I've been able to copy barcode/pass keys or decode other [location specific] information.
Hello! I love these videos, keep up the good work!
A lot of your videos it just makes sense to me and I am thinking that it wouldn't be too much additional learning for me to get into this field (not counting the whole thermodynamics/math part of it.. Lol), but then you cover some of the things like in this video where you have to understand stuff like the txv valve and identifying the restriction, or tying in the fire suppression and fire alarm systems into the control retrofit, and I am reminded to be humble, because there is so much that you may not use every video, but just know.
Thank you for sharing your knowledge and skills, and preserving these for anyone who wants to improve their skills, as the Canadian Beekeeper would say, you really "Promote the Brilliance"! Lol
I have friends who DO NOT do any preventative maintenance on their vehicle either, So i had the fun job of checking my friends vehicle out, The cabin filter was black and completely clogged, Air filter was black and full of grit, blown light globes all over the vehicle, on top of other issues. So my point is, if you look after some thing it will last a heck of a lot longer. Preventative maintenance is a must in my books.
Liked how thurow you were here! Only things additional I would have done is adjusted the belt with an amprobe to the motor plate amps and ran a acid test on the #2 stage system! Great video! Thanks for an awesome video!
Go back and do an acid test on#2 and if it tests positive for acid add some acid away to the system and you could avoid having a burnout! If all of this pans out let the customer know that you went the extra mile to save the compressor and you hopefully will have a customer for life! The others who were looking at the system before you damaged the condenser coils and most likely didn't purge the air out of their hoses and allowed air to get in the system so acid is likely in the system now and is causing the sludge that clogged your filter dryer!
Hey I am a computer dude, I need to become an AC repair technician! Love your videos, thanks for taking us along.
I really been enjoying the vids on ur channel keep up the amazing vids it helps me with the electrical work i do on model train layouts 😁
Thanks for watching
