The communication between Chris and the crane operator and the crane operator's precision looked extremely skilful! Although I do not work in HVAC I very much enjoy your videos.
A TEXTBOOK PICK . . . FROM THE TAGS TO THE SOFTENERS . . . CLASS ACT.
Rest in peace, sweet prince
Definitely gotta check everything out on a new unit with current quality control procedures at the factory. We had 2 different York package units come in with loose set screws on the blower pulleys and motor pulleys. Unfortunately, our install guys aren't the greatest at checking everything, so it ended up being a service call that was handled by myself and another service tech.
I went to look at a Pool Heater for a friend. The installers filled out the start up card,listed all of the numbers upon start up and the specific run times etc. Well it wasnt working,so I look in it and it was never finished at the factory! Equaliser line,just hanging in the breeze,valve fitted but not brazed,i couldnt believe it! Never seen anything like it.
York is garbage. Big garbage.
exact same thing happened except it was missed, i showed up to replace a filter and all i hear is BOOM BOOM BOOM BOOM, i ask how long it's been doing that for, they said oh about a month or so. i said why didn't you call? they then became irritated and look at me like i had a dick growing out of my forehead
It’s good to see people who think ahead and plan for the other trades working together. It’s something I see disappearing on job sites. Keep up the great work Chris love the content!
In regards to what issues you are finding with new equipment; we just received two server room systems from a reliable, and very expensive brand name, that took 10 months to get. They are both two circuit units...all four circuits lost their nitrogen charge, flat. 5 of 8 compressor rotolocks were loose and could be turned by hand. One of those was completely back out and the suction line was just hanging. There were several other issues but that was the big one. I've been servicing and doing start-ups on this brand for at least 25yrs and I've never received such a mess. And, I'm hearing similar stories from so many other techs on so many other brands. Strange times.
Excellent footage Chris.... Thank you once again for an entertaining and educational video! I get a lot out of this. I have been offered an apprenticeship with a local HVAC company here in Florida. Apparently I said some interesting things to a supervisor that was at my house when the tech was here installing the new condenser fan motor. This is partly due to the informative, educational, and entertaining videos that you have been producing for years now... You have a fan for life! Please keep the package unit videos coming.
I'm impressed with how messy these devices are, cables run everywhere, PCB exposed, no markings on components, contactors with exposed metal live parts. It's crazy and it makes a lot more work for you.
I work in building automation in Poland and every roof top / air handling unit have separate cabinet for electronics usually dust and air tight (IP56 +), cables are in PVC perforated cable ducts (plastic wont cut insulation on sharp edges). Every component that might have live potencial have bould in covers that there is very small chance for finger to touch. And documentation, there is usually PDF wich schematics available from manufacturer and every element in cabinet is clearly labeled.
Don't get me wrong, You have exelent troubleshooting skills and a lot of times You make it easier for the next person to work on the unit. Its just much less safe compared to units in EU.
They make the package units here in the US cheap to buy and expensive to service. That has been the way for the past 20+ years now.
Sadly, we have a LOT of catching up to do to be on par with the EU.
It’s great you perform a thorough commissioning, most rtus I encounter have dampers, drive units etc. overridden. I think about how much energy we can save as a country if rtus (all hvac actually) where tuned and balanced correctly. I wish there was more incentive for owners to pay for energy audits and corrective measures.
I'm in the Uk and retired from a diferent trade but Chris I just love to watch this professionalism and your dedication. Not only that, the attenton to the video production is spot on too.
"The customer bought all the equipment." This makes me cringe every time I hear that. As an IT professional (retired) I've laid out precise specifications to clients on what they NEED to order. And some simply just go off on their own little power trip and modify the order to their own specifications, which pretty much wrecks the entire set up. I request a server with such and such storage space, and they order one with HALF, I'm stuck with ordering more drives to go into it, or RAM, or even the lack of a second processor, which really made me steam. There have been at least two instances where I've simply laid down the law, stating it has to be like this or we will have piles of useless scrap sitting in a corner gathering dust. And doing RMA's on custom built hardware is not cheap.
What Trane did there with this kit, you honestly should bill them for the refrigerant used, the time used to fix their little issues, and the rest of the dings and goofs they didn't catch during QA (if they did any, some of those goofs honestly should have been caught at the plant). And if the next one comes with all the accessories boxed up, just bill them for their BS. That is simply not acceptable.
In this case customer provided equipment matched close to original engineered specifications...
Its sad how much you have to double check new units now. We had that identical brand and size unit we just installed a month ago. Customer had been waiting over a year for unit. Fired the unit up and it ran for a bit and shut off. Long story short after much head scratching we found they had hooked up the equalizer lines on the txv backwards and hooked up the sensing bulbs backwards so two stages were linked and pumping the refrigerant from one to the other. So much for quality control at the factory and test running them before they send them out the door. Oh and the lp conversion kits were missing so they also had no heat for a month till we got that straight.
On the note of safety, something I always watch for and saw your team handle properly: Never EVER stand under a suspended load, or put anything under a suspended load. If one of those units were to fall while suspended at any point, a person underneath or sometimes even near it can make a very bad day much worse.
At one point, I think I heard Chris shout at one of the techs to 'GET THE FAWK AWAY FRIM UNDER THE LOAD' and said tech scurried away...
@@kaptaintrips can you add a time stamp?
@@Samthe17 I don't think he actually says that, but it does look like it at 7:42
@@uzlonewolf You couldn't hear it but the tech did in his mind and quickly moved in the proper direction:)
I miss HVAC/R...Watching the brazing...I miss it, truly. Thank you for this vid! Really good stuff.
Thanks Chris. Monday I start with another mechanical company with a $5.00 an hour raise. Watching your vids for the last 15 months with a legal pad taking upwards to 6 pages of notes, my remote to pause and rewind, and letting your big picture diagnosis mentality become a part of my day on the roofs have paid off. My interviewer grilled me on my knowledge and it just flowed right out of my mouth like an old pro. Can't thank you enough and the HVACR hat is getting a lot of comments at the parts houses. You're the best!
This video is really unique.
1. I remember the footage of the first video with the awesome Epidemic Sounds music
2. Night time footage
3. New unit installation at Dawn
4. Parking lot footage. (I am wondering why more HVAC units was on that trailer)
5. LG compressor (Instead of Emerson)
6. Chris forgetting to put plugs of compressors
7. Freaking VFD running at 62.99hz when the system frequency is 59.99hz 🙂
I have a grim feeling about the build quality of this RTU and its LG compressors, but time will tell.
I still saluted the old. Unit on its way out for its service
I recently had a scary issue while picking a 120 ton rtu in a city. We use 2 way radios to talk to the crane and on this day another crane pick came through our frequency when we were 6 feet above the curb and some of the guys were in a very bad spot. The other crane crew kept saying lower and boom down… nothing bad ended up happening, we adapted and overcame.. still shit my pants
Check the manuals and see if they have privacy codes and set them. Most hand radios are license free so the advertised 128 channels is really only 22.
Crane operator I know stuck a cam on top of the boom so he could see downward onto the target.
A few years ago I helped installing cameras on trucks. I know that the ASL360 system we installed also got installed on some cranes and excavators etc. As this was a few years ago I'm sure there are even better systems out there now.
Nope he was just using my hand signals , i've never worked with an operator that had a camera system....
@@HVACRVIDEOS I can't imagine being a crane operator using a fish eye to move a large load...
...shivers... may that day never come. Subtle and profound hand signals will last for my lifetime I do imagine. So, maybe by 2055?
when i was a working man we installed 5 -10 ton lennox units, we ran 1 inch copper drains traps about 10 feet copper pipe, a few days later we got a call" you didn't run the drains' someone stole the copper
I am in my 2nd year of college and 8 months into my new career HVACR!! I absolutely LOVE your videos!!! Thank you so much. I'm working residential/commercial but plan to go full commercial. I've learned so much thru watching your channel. Keep it up please
Still my favourite equipment brand by far. We work on tons of these. Well designed and easy to service especially with door hinges and door handles
"1,2,3 please don't blow up", I don't even work in the same industry, but I reflexively squint every time I power something.
HVAC guys, how is the quality control coming from your vendors? I'm in the telecomm industry and ours took a steep dive off a cliff from 80% of our vendors spring of this year. Straight up dogshit now.
The only vendors that didn't send us trash are American, European, Japanese and Mexican vendors, we get big trunk amplifiers and nodes from Mexico and they're 10/10 every time.
Nice to see an interlink dampermotor, which is in fact a Siemens unit
Wonder if it has caught fire yet
@@Powertampa Because?
Chris, this reminds me of some of the rooftop jobs we did at schools for renovations. My foreman actually made a roof buggy to move some of the smaller units closer to the crane. We sometimes did 20-30 units in a day.
One trade school had the HVAC students doing the entire installation with their instructors, saving a good chunk of money on that job, and giving them valuable hands on experience. We did the mechanical demolition on that job as the students were limited on time, tools, and techniques, though it would have been a good experience to teach them some of what we knew and did.
Chris, I really appreciate your channel. I'm a retired NucE and EE and for practically my whole career I had an HVAC/R company as a second enterprise. I haven't worked in about 15 years so I really enjoy seeing what is the current state-of-the-art in both hardware and service techniques. Thanks again, John
Balilbondsh?
@@kaptaintrips WTF?
OMG you had me laughing my ass off Chris, when you said you pulled the red caps off the smoke detectors, I had 10 units I had to see what the hell the monkeys did and found out that what it was those Red caps were in every unit, I was like come on guys what the hell, and all the shipping metal shields where left on the compressor feet. My boss the owner of the company we pissed he had to send me out for such stupid shit. I think that was the last time those guys worked on the same install crew. lol
Excellent video to see the whole major process
This is very cool! In previous videos the lift part of your equipment is left out for time saving i'm sure, but if you get to do this again, can you maybe take some distance footage play it at the end? Maybe a 2X speed clip? Purely for fun. Love the videos and thanks for sharing!
Hopefully, someday we all get to see a sunrise mass swap out or new install with a helicopter or two from your channel ;)
I haven't seen a hewie used in quite a few years now but damn, it's efficient!
That was a great video dude, it was cool to see all that heavy work going on.
Epic video! Love the tech work, and on top of that we got the whole crane process. Thanks brother, really appreciate the effort put into all of these videos. I am always glued to my screen beginning to end
Been following this one, glad to see the conclusion! Well done!
another package unit change out vid, always my favorite! Interesting to see the startup process.
Spend all that money on a new unit that supposed to be close to ready to go right from the jump.....yet you have to do all this extra work to get it to where it was supposed to be out of the box. The little adjustments and added accessories....ok fine...no biggie....put wires on relays...adding refrigerant.....no bueno.....quality control has gone to the birds. As always another fine job at getting everything up and running as close to design as possible
My van is full of used parts! Boards,fan motors,Caps ,etc! When we do upgrades,I have always gutted them,and kept the parts! The bosses want to know why I dont spend much money compared to the other guys,its my idea,it keeps me outta the woods,and many disasters avoided. Nothing wrong with known good parts!
I have never seen one of these machines being swapped, it's cool
26:10 I always open the return panel to let it go out through the outside most then it going inside the building. Those cables on that 1st stage compressor gets me ocd lol could cause a short and melt those wires. Good video Chris.
finally got that unit, one of our local HVAC companies has a flatbed crane truck it brings in the new unit and takes away the old here in southern Arizona
It’s hard to understand the scale of these units when you’re working up close with them, so I found the video while you were lifting the old unit off the building pretty fascinating.
I really like the view of those yellow lights. We used to have those in Sweden many years ago. Now it's all led with the harsh blue light. Really miss the old days in a way. Those really do look so much better. I perfer the warm color.
High pressure sodium, you can still order them.
SOX are even nicer but good luck finding them in use anymore!
Perfect install.great job
Chris, I really enjoyed this video. You’re videos just keep getting better
Another great installation & startup!
I work for a company called vertiv aka liebert that builds industrial ac units and your videos are so interesting to me.
I’m still saying to the end of the videos since you explained it on your live channel, hope it helps the channel more because I do truly enjoy your content and I learn a lot here
good job chris keep up the good work and stay safe
Chris, nice clean installation with safety in mine 👍. I know you addressed the wrong orientation of the gas line sediment trap but for the life of me I don’t understand why you didn’t correct it at the time of the installation , A nipple tray and elbow and 10 extra minutes (you’ll have explain it to me, why it’s better to install it wrong and come back later). I didn’t know it was approved by the furnace manufacturers & NFPA54 to use a flex connector between the two interior gas valves with a cabinet wall between.
So I don't do enough gas line installs to carry any gas pipe and or nipple trays... I brought it to the customers attention and if they approve it i will correct it
Also the manufacturer is the one that installs that flex from gas valve to gas valve
@@HVACRVIDEOS , I thought they may have installed it. It does make sense with all the movement and flexing when the unit is supported by a crane. Thanks for the feedback and hopefully you are enjoying the LA weather this week
Awesome video Chris!!
How much money has gone into that? You told the owners over and over it was on its last legs and now they have to stump up full dollar in one hit! Well done on keeping it going 👏
You have to do what you can. Nobody wants to eat in a restaurant thats 90degrees. Weve had to take parts off of old units in our scrap pile or other broken units on the roof to make systems work because units are so far out. We have some that replacements were ordered a year ago and still waiting. You have to do what you can to keep them operating.
After over a year of waiting you finally got a new unit
Mam, your crew had such fluid teamwork on the crane work bro, touche' on great leadership Chris!
I always try to harvest parts when I can, no reason to throw away parts when I get try to get someone up and running and keep them happy. Sometimes I have generators that I have to wait a week to get parts for and I can pull parts off old units we send to scrap to get units running.
I will discuss this on my Livestream this evening 10/24/22 @ 5:PM (pacific) over on CZcams , come check it out czcams.com/video/bHwhvet7lrM/video.html
I love watching the vid from you chris.
But the comp in the new unit Is LG if it fails can you change to Copeland
Talk about commissioning... had an 18seer cu with ecm fan motor, technician didn't pay full attention but it came from factory wired wrong. 24v signal wires were hooked up to high voltage and vise versa. Fried the module instantly. Brand new unit out of the box, never been sold to anyone else, rep kept telling me that it's impossible since they test run them at the factory, clearly not 🤦♂️
Did you also harvest the 2 compressors you put in in May? Or did they get scrapped with the rest of the unit?
Came here for a new AC install and 80s porn music. This video delivered. Liked and subscribed. Thanks bud.
Wow that Lennox looks very tech friendly, especially that prodigy board. Looks like a (relatively speaking anyways) quality product. I worked on a couple of similarly sized 460v new-ish Yorks recently, which are absolute crap in comparison and somewhat of a pain to work on. Only unit I’ve worked on worse than those was a 20 ton Daikin package unit.
Yeah they are the Cadillac of hvac units..... I've always liked them
@@HVACRVIDEOS I have the same impression of Amana… for residential units anyways
@@gregmercil3968 I used to have the same feeling for Westinghouse units...
Finally, some closure on that particular unit!
When you replace an old unit that has a nearly-new compressor as a result of an emergency repair, what do you do with the nearly new compressor? reuse it? scrap it? sell it on ebay?
Nice paint job on a new machine
When you find issues like the door and wiring do you report it back to the manufacturer so they can improve their processes/QC procedures?
Hopefully improvement is the end goal....
On a more cynical note, you should always, always, report problems with as-delivered units to the supplier, so that you have liability protection. As the installer, it's not really your job to make sure that information gets back to the manufacturer, nor do you really want that kind of time obligation. Worse still, some suppliers might see that as you "going over their head", making it harder to get parts in the future.
Just curious if you measured the unit airflow? Measure quick was showing ~6,800cfm which is more than the 400cfm/ton for a 15 ton unit. I normally check gas pressure / adjust it to the proper pressure for the BTU content of the local natural gas supply and then do a temp rise test and calculate the airflow on new installs and then adjust the motor pulley for the correct airflow before balancing the building. If the airflow was high it would explain why you thought the TD was low, but measure quick said it was close to the target because it had calculated a higher airflow.
finally I can see package unit new install
Last night I was getting ready to go out to dinner with the wife and she looks at me and says “are you going to wear that she’s a leaka mama shirt to dinner?” And I said “it’s a HVACR t shirt, and no” lol
Now Chris, no more problems to that unit for 10-20 years as units should last a long time, one less customer to worry about now.
Your sense of troubleshooting and these videos have teached me alot sir, keep doing this great work 🙏🏻.
I felt u accidentally posted the first video clip from a different unit, could tell by the molex connector at compressors. But overall once again you have teached me alot of tricks and troubleshooting techniques in my career. 🎩hats off....
Taught
I appreciate the use of headlamps.
How often have you found the ductwork connected to the unit underside?
Let me add, those turn knob disconnects will fail and we've had to replace with a bigger disconnect.
I'm curious: do you ever provide feedback to the vendor about the stickers being upside down? This is surely a minor point, but a quality one nonetheless, and a quiet report (not risking a return) might help the vendor with their own quality processes.
16:48 Um... quick question, did you know that black lead is supposed to be line one and the red lead is what you move between L2 and L3?
Labeled on meter. Took me two times till I figured that out on my 460? The one with rotating clamp
Although I see this and wonder if it even makes a difference
Looks like your crew has done this before! Nice job,
Yes whenever we replace units I take out all the good parts I can.
Thanks!
Good Job Chri5
Only push in contactor with a non-conductive stick. NEVER EVER EVER with your finger. You'll learn that after you lose your finger.
"it's polishing a tur..." *is a brand new unit.
Tha's a beautifully shiny new unit
I may be wrong but it looks like you tested for phase rotation using red as L1 and black as L2/L3 but have hooked up L1 to Black on your meter.
I wondered if we ever see that unit replaced - HERE IT IS XD
Does anyone know the name of the song/music playing when they're hooking up the old unit to the crane around 6:00? Sounds so chill...love it.

Yea I want to know it, I remember hearing it before!
Where did you get the music for the montages-- especially the tune playing during the crane removal of the old unit? 4:20 - 7:50
🤦♂Edit: I just love using autocomplete while hungover.
LG compressor owesome 👍🏻
Hey great video. What type of compressors ?
Love the vid ❤
Can you plz explain the condenser pressure drops? Im clarification u mean the difference between discharge and condenser pressures. What would that be in saturation diff?
The difference between the liquid pressure and the discharge pressure
@@HVACRVIDEOS what was the pressures to get a 15-17° differential
I don’t like changing roof top it can get scary.
Hi Chris, whats the release date of the previous video?
A much better crane operator than in an earlier video.
I should have waited till later in the video as I saw they capped the inlet to the trap.
Why the copper drain lines? Mostly pvc here
I sell a lot of copper traps doing service work because pvc ones crack and fall apart after a few years in the sun.
SAFELY FIRST! GOOD 👍
Finally a whole new unit
Sweet, man.
I once witnessed a chiller replacement by helicopter, can't imagine how expensive it is to replace them on high rises
Why did you add suction driers on the new compressors?
As always, an outstanding job Chris!... As a 30+ years Electronics service tech and business owner myself I really enjoy the quality of your videos and excellent experience as a tech in every aspect. It's good to know there are still AWESOME TECHS out there striving to be the best at what they do and be good honest people like you Chris.
Beforehand, I apologize for my english and any spelling errors... My English is quite rusty, dating back to my days living in Texas in the early 90s...
Greetings everyone, I am writing from Argentina. I used to be in the HVACR trade in my mid-20s in Houston, TX, but had to abandon the trade due to health issues, Yet I am still fully active with other trade... My 30+ years as a Senior Electronics Tech & Designer so i've been out of the HVACR trade for a long time... I do have an unrelated question to this video, that, some active and still working techs here may be able to help me with...
A friend of mine has a small datacenter that is cooled and maintained at 70 degrees, with a york 5-ton split unit model YMSFYH060BAAKB-X that was purchased used, installed as in "Cooling Mode only" unit. in recent days he's been running into a few issues with the unit not cooling down properly. Condenser and Evap coils have been cleaned, contactors and caps replaced... AFAIK... had the "works" done two weeks ago. The Datacenter is located in Monterrey, MX with an average outdoor temp of no less than 85 degrees all-year 'round. My friend commented to me today that he called an HVAC tech today about the lack of cooling and the tech said the following: "To have a 350 to 450psi high pressure cutoff pressure switch installed in the high side to CUT OFF the condenser blower b/c the outside blower runs non-stop along with the compressor, that apparently is overheating and tripping out due to LOW PRESSURE ON THE HIGH SIDE (250 psi) and by cutting off the outdoor condenser blower, RAISE the high side pressure. I am really at odds with this b/c my old-school knowledge as a young apprentice tells me that, it would be UNWISE to cut off the outside blower with no other overtemp and over-pressure protections other than what's inside the compressor as that could put the compressor in a overtemp or short-cycle situation or worse... My friend tells me, the compressor has been trippin out on over-temperature as I guided and helped my friend to find out. I do lots of work him and for his datacenter remotely and from his datacenter I host my website for my tech and electronics business along with a dedicated remote storage server.
Guys... I could be wrong here... I do not have much experience with split units... I did all my HVACR work in the 90s and early 2000s in package units up to 50 tons of the day... I really could use a recomendation or a suggestion as to how to guide my friend, as the servers need 24/7 cooling. He's never had this problem before and having watched Chris' videos and of many reputable HVACR channels for a long time now, I come to the realisation that my old knowledge and practices are sound. I get the feeling that they are trying to set my friend up for a "future" short-term failure... Kinda like having to suddenly change a car battery at a mechanic's shop without having the alternator checked to ensure it's properly operating and charging, so that you have to visit him AGAIN and have the mechanic charge you even more labor for an already BAD alternator, that went previously unchecked when the mechanic replaced the battery in the vehicle... Y'all get the point... so they can scam him out of more money. I will appreciate any help or comment. Thank you Chris and tanks Everyone!
a new unit... comes with a mess or wiring... good god... can't stop shaking my head as a german electrician....
Pretty horrible that you buy a very expensive assembly from a company that specializes in that, and it's a total shitshow. At some point, you've got to send them emails with the faults you find, so they can track down the worker that is taking out their frustrations on the products.
Liked the video 👌
with that intro i was half afraid you were on another limp mode service call on that thing.
