Wait till you see what some people neglect on their cars. I bought a truck in 2019 that had tires from 2004. local highway department says they should be replaced every 5 years or when tread wears out whichever is sooner.
"Let's let every ac break down before calling the service man, its probably cheaper that way then to have him inspect and repair if needed to the ones that still work" bill: 25k
It's probably that s a lot of restaurants have either been shut down or barely surviving during covid. Across the country thousands of restaurants have gone bankrupt. Fixing broken ac or make payroll or rent. You know it needs to be fixed but there are immediate concerns.
@@janquantrill9585 it's coming, were back on curfew restaurants have to close by a certain time, building capacities are being lowered, people are stocking up and buying multiple freezers and things
getting paid the hourly cost´s of a worker isn´t the part you make the money with. buying the parts and whole devices with up to 60% off the listed price and selling it to the customer at listed price is making the money. but to be honest... crappy design of an AC device. Way to much unecessary copper tubing between the parts, what is one variable which determines efficency. i can sell you 23 kw of cooling/heating power in a mashine a third its size. Without the danger of getting mold delivered into my room.
@@locomotive1213 of course the supercompact version of that machine still breaks, but the tech can’t get in there to repair anything so it needs to be replaced.
Oh yeah, pretty common in every restaurant I've seen and really that's nothing compared to hotels. I've actually seen chairs stored on the fire escape stairwell landings!
I really wouldn't like the idea of replacing whole units tho. Especially after seeing walk ins with non-hermetic compressors with R-12 installed in the 60's that are still running in chem labs at my university. That being said the compressors are indoors with just the condenser on the roof and the university always has the cash to spend on PM.
Before I had my own business the company I worked for would only allow us to get them running no matter what. Dump thousands of lbs of R22 in systems and never go back and leak check or fix the issue. Now this was on a federal installation. On one of the major stores I had 62 rooftop gas packs and because we were not aloud to do a proper PM we had to replace almost half of them in the first six years. That’s when I went into energy management then opened my own business. I successfully bid and won contracts for over 30 federal institutions throughout the eastern cost. It was a rewarding adventure for me.
I admire how you handled this one/job/call like a multiple car accident and you treated all these units like they were human beings and you were the Dr. Good Job Brother!
I got recommended your videos earlier this year and ever since then I could never stop watching! Even though I know very little about HVACR, I feel like you’ve taught me enough to know a little more than the average person.
1:18 I work in IT and we once had an entire server room go down because of that issue - it blew the MAIN breakers to the entire room and dumped the entire load.
@@thomasbell2644 The TAFE I used to attend had three server rooms, one was a dedicated for Netlab. They used to have the mains power for all three server rooms go down (it wasn't their issue). With the result being that the student network ended up being hosted on the Dedicated for Netlab server. Oh and the Netlab server also had an AC issue, it had none with the result being it was prone to overheating.
Datacenter guy here. That's why we run daily checks on all our CRAC units, including logging measurements for historical reference / trending. We also have temp monitors all over the room in addition to airflow sensors so we get notified if there's an issue before it becomes a problem. Cooling systems are not to be taken for granted.
Have a buddy who works in it at a hospital. They had a power failure on the main power. That then went to switch over to generator and for some reason the breakers/ transfer switch then failed all of this was at night. Couldn't find maintenance to reset breakers for generator, it went to the ups backup witch completely died as it never switched over to generator power. And the whole hospital went down. Voip phones, every computer, etc took 2 days to bring it back on line completely and recharge the ups & inspect. Then chase down all the remaining gremlins
i won't say you should stand behind the professional and watch them the whole time, but its ok to check back like every hour or two and offer them something to drink and have a short chat about what's wrong... it shows you're interested and have the guys work properly.
lol, that pickle fork tool is an automotive tool used for separating ballpoints, that said, i too use it for several jobs that they were never made for simply because they work
@John Doe Fast and cheap doesn't mean it'll last long. Which means more work for the techs over a long period of time, good for the bank account. Strong and solid means you fix it once and it's good till your no longer around...I would still rather do the job properly rather than bodge it, every time.
@@matthewsykes4814 They are called wire nuts. They contain a tapered coil spring inside that twist (to some extent, depending on if it's solid or stranded wire) and compress the wire ends together as you tighten them. They are actually deemed to have both a larger contact surface area against the wire and form a stronger connection than a Wago when properly installed.
Chris - A minor point but the belt is made with Kevlar which is 5x stronger than steel. The belt can eat the pulley, it was the old belts that were much softer. Today belts don't break in, except for shape (going from something like a figure 8 to an oval 0). Once the shape is beat into the belts the belts then break in the pulley, that is if the belts are made with Kevlar. That is why you should never slow a spinning pulley with an unprotected hand, the belt can wear a very sharp edge in the pulley.
As a master card access tech, it’s comforting watching another professional work from the comfort of my bed. My neck still tenses up when you run up on other companies inadequacies and customer ignorance.

Thank you for doing what you do. Your videos are informative, easy to follow and understand. I like your "big picture" approach to things. Wish I could learn from someone like you.
Wow. Reminds me of my younger days when I serviced tons of this kind of worn out junk. Rooftop units are out of sight - out of mind. They tend to get ignored until they're totally broken, like these units. I've seen some horrors on roofs, and the customers still didn't want to spend the money.

Thanks for all these videos! Having my 3rd year of college during quarantine is a bummer and these videos have been somewhat keeping in the loop/rejogging my memory
I understand how you feel. I worked one summer in Myrtle Beach, SC. At that time most of the city's 40,000 motel rooms used Feder's window units and where I worked provided the service for them. When one was down, the room could not be rented, so motel managers were desperate for a fix. I worked in that miserable heat and humidity for 10-12 hours a day six days a week. The only good news is that I had lots of money for college come fall.
Every day (or at least every time I see a situation like this) I thank my lucky stars my father taught me the importance of preventative maintenance. OTOH, it is revenue for guys like you. ;-) Good job my friend - I always learn from you.
Temp fix for that bad pulley. Wind string around it till the belt won't stick good for a few days till the part comes in. Works for me and the customer appreciated the cool.
It's tough for restaurants right now, cause they don't want to spend on keeping mechanical in good shape because it's not really a large return on their business and if it's functional it'll cost even more, but it's tough for you cause it'd be nice to see everything in good shape
Great tip for the clo board! I always just checked CLO terminal 3 to ground to see if I have 24V. FYI for newbies, to bypass a faulty CLO jumper terminal 2 to 3 for temporary cooling.

i live in the netherlands and i have been following your video for a while now. still there are many differences with usa and europe regulations. like propane wii they have to pump back if not 10,000 ticket we also have to give up every gram of loss otherwise ticket and much more hassle
Some quick fixes on many units,,,, It is sometimes to easy to rush through a simple problem ,, reset a high pressure switch and miss the real problem that was the cause ,,,, I did that many times , sometimes because the foreman wanted people to get around to many jobs and achieve the impossible..... Thank you for the video,
Seems like your work is starting to pick up! That’s good, let me know if you need a hand on the weekends, I’m in the Los Angeles area. By the way love the videos, your straight to the point and you always seem to find the issue!
If the sheave is worn down like that, the balance is off and airflow is most likely too low. Most balancers are trained to set sheaves to achieve around 350-400 cfm/ton for efficiency. Closing the pully 1/2 or a full turn probably wouldn't be a bad idea to get by in this case. Love your troubleshooting. It helps me out alot too.
Just before this video I was watching an older one of yours (from last year, I believe). In it, you added new pressure controls (near the compressor) because the old one had failed. Now I'm watching this and when you got to the 5th AC showing those pressure controls, I'm like "wait a minute, that looks very familiar!" What are the chances? ^^
Nice channel, great attitude. I'd like to point out than no expert should try to do anything in this video on his own, especially after turning the power back on, not to mention working with bear hands, without gloves and uninsulated tools. At 24:30 you really see that only a few minutes of cleaning can make wonders... thus the AC will run smoother, your pocket will thank you for that... keep up the good work.
Went to school for hvac dropped it when I only had a summer thing left. Wish I had went after it more. Started two business since that are doing great regardless. Still got that feeling Now atleast. That I would of enjoyed hvac a little more having businesses in that field. Maybe oneday who knows. Can kinda kick myself now. I mean I still know enough to do my own fixes an get my own back up an going. But long as it’s been unfortunately forgotten a lot. Enjoy your videos man keep em coming.
First thought I had was someone flipped a three phase supply for everything and never checked rotation. I encountered one where the building was renovated the electrical service was replaced. Someone only checked rotation on single phase fan motors and it turns out the original service had rotation flipped in a few spots so three phase compressors turned backwards but the fans turned the right way. They were just lucky that it happened in winter and they hadn't damaged anything from turning compressors backwards.
Ever work on a vrv unit.... I'd appreciate a video to understand them better. I barely started watching so not sure if you already have one. Great videos, great tips.
You should make a vid were you explain certain parts just need replacing to prevent full loss of a unit. People sometimes just dont get why something needs to be replaced and why it will cost them more if they dont...
Using a I call it a pickle fork but it is really a ball joint separator either way it is really hard on the front bearing of the motor especially when the pulley is bad a 3 or 2 jaw puller can save some expense but that is what kept us electric motor techs in business
After years of searching for the perfect loose hamburger, a Papa's Coney Island moved into town with some of The Best Loose Hamburgers, but the lock down here in Michigan forced them out of business. They didn't even make it to opening for take out only. No one around here wants to put any money into anything. Just get them up and running for as cheaply as possible. I can't remember how many 1609s are now in place of electronic controls on those cheap prep tables, and it doesn't look like it will end any time soon.
I had this happen to me after a serious thunder storm. The call was every AC down in a supermarket. When i got there all the AC's had supply voltage but the EMS system was locked out. Right there my first thought was the fortune I was going to charge them to jump-out every RTU. As Im coming down the ladder inside the store. I glanced at the Fire Panel. And that's when I noticed it was tripped and was causing the AC shutdown. Crap.
I think the rinsing of the airconditioning radiator is so satisfying. Almost feeling of doing our on on top of work. (It's on a maintenance contract though)
Last year I replaced 33 of those stinkin' Weather makers on one roof. I was glad to see them go, 20yrs old! There were the same 7 or 8 that constantly needed attention or repair in the last year.
seen some replies about the wiring well here to in quebec it is baaaaaaaaaaad i'm a machiniste welder on site and used to be in ventalation and it is pittyfull here to but your vids are nice and because of you i miss this ;)
I would agree about intermediate short i would check the leg that has a different fuse at the disconnect first . I like you videos good luck with all thoses poor neglect units.
I worked on those type of units and larger (Trane Carlyle Etc) in the 90s in the UK also quite a few water condensors Baltimore A C and a weird thing where the indoor units had a reversing valve so could be heating or cooling called versa temp but I think that was from the UK 3 phase power is 415v over here
Thank you for talking about the customers side, it is easy as for us Techs to get frustrated with sub par equipment, but to think about it in a way to understand the customer, is the right way! We can only do what we can! Good job! If not receiving cash flow because of the shutdown then yeah of course they just want maintenance because of their uncertainty.

Thank you for the video,
Awesome work always learning from your videos. Thank you
Chris: "These contactors all look okay"
Everyone else: "😮"
lol well the units are junk heaps anyway
I guess spider web isn't that flammable?
Thank you. Thank you. Now i know whats X is for!!! That was my question on the other video!!!! 🙏🏼
Seems like your work is starting to pick up! That’s good, let me know if you need a hand on the weekends, I’m in the Los Angeles area.
By the way love the videos, your straight to the point and you always seem to find the issue!
I remember that restaurant! The good old days. Love the channel man. I just bought a hat from the store.
If the sheave is worn down like that, the balance is off and airflow is most likely too low. Most balancers are trained to set sheaves to achieve around 350-400 cfm/ton for efficiency. Closing the pully 1/2 or a full turn probably wouldn't be a bad idea to get by in this case. Love your troubleshooting. It helps me out alot too.
You Guys are Awesome to do what you do.
Keep up the great work and thanks for the content stay safe and take care
respect , always enjoy checking in here
love all the cardboard piled up in front of the breaker panels! That's how a Papa John's I worked at 20 years ago burned down.
Just before this video I was watching an older one of yours (from last year, I believe). In it, you added new pressure controls (near the compressor) because the old one had failed. Now I'm watching this and when you got to the 5th AC showing those pressure controls, I'm like "wait a minute, that looks very familiar!" What are the chances? ^^
Nice channel, great attitude. I'd like to point out than no expert should try to do anything in this video on his own, especially after turning the power back on, not to mention working with bear hands, without gloves and uninsulated tools. At 24:30 you really see that only a few minutes of cleaning can make wonders... thus the AC will run smoother, your pocket will thank you for that... keep up the good work.
Great Video
Thanks for Your
Expertise Take Care
Went to school for hvac dropped it when I only had a summer thing left. Wish I had went after it more. Started two business since that are doing great regardless. Still got that feeling Now atleast. That I would of enjoyed hvac a little more having businesses in that field. Maybe oneday who knows. Can kinda kick myself now. I mean I still know enough to do my own fixes an get my own back up an going. But long as it’s been unfortunately forgotten a lot. Enjoy your videos man keep em coming.
Busy day, I like working on those problems. It makes the day go by faster.
First thought I had was someone flipped a three phase supply for everything and never checked rotation. I encountered one where the building was renovated the electrical service was replaced. Someone only checked rotation on single phase fan motors and it turns out the original service had rotation flipped in a few spots so three phase compressors turned backwards but the fans turned the right way. They were just lucky that it happened in winter and they hadn't damaged anything from turning compressors backwards.
This is the kind of stuff I see a lot when I live, cheap customers, and they never have their equipment serviced and when it fails it bad lol
Your job is extremely important, sir.
Ever work on a vrv unit.... I'd appreciate a video to understand them better. I barely started watching so not sure if you already have one. Great videos, great tips.
I’m jealous of the good water pressure you always seem to have. It’s hit or miss on the east coast.
Getting that way out west too! Lower pressure all the time, the state would instead divert it to Nestle, 🤬🔥☠
Those units look tired. I can see disasters coming down the road for most of those units.
gbowne1 time to rebuild them... or replace them with a crappy new one.
Typical restaurant - don't replace anything. Just get them running.
You should make a vid were you explain certain parts just need replacing to prevent full loss of a unit.
People sometimes just dont get why something needs to be replaced and why it will cost them more if they dont...
Using a I call it a pickle fork but it is really a ball joint separator either way it is really hard on the front bearing of the motor especially when the pulley is bad a 3 or 2 jaw puller can save some expense but that is what kept us electric motor techs in business
After years of searching for the perfect loose hamburger, a Papa's Coney Island moved into town with some of The Best Loose Hamburgers, but the lock down here in Michigan forced them out of business. They didn't even make it to opening for take out only.
No one around here wants to put any money into anything. Just get them up and running for as cheaply as possible. I can't remember how many 1609s are now in place of electronic controls on those cheap prep tables, and it doesn't look like it will end any time soon.
I don't have a clue about ACs, they aren't that common in Germany, but I really enjoyed your vid. It definetly teached me some stuff.
8:12 lol blown fuse just kicking there at the bottom of the box for who knows how long
ohh men!!! new tech here and i learned a lot with this video a lot off problems haha thanks for sharing.
I had this happen to me after a serious thunder storm. The call was every AC down in a supermarket. When i got there all the AC's had supply voltage but the EMS system was locked out. Right there my first thought was the fortune I was going to charge them to jump-out every RTU. As Im coming down the ladder inside the store. I glanced at the Fire Panel. And that's when I noticed it was tripped and was causing the AC shutdown. Crap.
I think the rinsing of the airconditioning radiator is so satisfying. Almost feeling of doing our on on top of work. (It's on a maintenance contract though)
Great Video Chris..very in depth..keep up with your great and informative videos! You Rock!
i love watching these videos knowing that i will likely never use the information i learn in this. great videos though!
Stay safe out there.
Wiat, a bunch of contactors did not need to be replaced??? You feeling ok? Keep up the good work and work safe.
Last year I replaced 33 of those stinkin' Weather makers on one roof. I was glad to see them go, 20yrs old! There were the same 7 or 8 that constantly needed attention or repair in the last year.
seen some replies about the wiring well here to in quebec it is baaaaaaaaaaad i'm a machiniste welder on site and used to be in ventalation and it is pittyfull here to but your vids are nice and because of you i miss this ;)
I would agree about intermediate short i would check the leg that has a different fuse at the disconnect first . I like you videos good luck with all thoses poor neglect units.
Blimey Chris you had your work cut out there? Nice job on getting them up and running? Keep safe dude
25:23 “A bunch of SHTUFF is getting sucked into here” haha
Nice Video 👌🏼 Looks like there’s some money to be spent on that site !!!
Great work 👍🏻👍🏻👍🏻 like all videos Very helpful thank u
I worked on those type of units and larger (Trane Carlyle Etc) in the 90s in the UK also quite a few water condensors Baltimore A C and a weird thing where the indoor units had a reversing valve so could be heating or cooling called versa temp but I think that was from the UK 3 phase power is 415v over here
Thank you for talking about the customers side, it is easy as for us Techs to get frustrated with sub par equipment, but to think about it in a way to understand the customer, is the right way! We can only do what we can! Good job! If not receiving cash flow because of the shutdown then yeah of course they just want maintenance because of their uncertainty.
Nice soldering, you are good!
Always intresting to see diagnostics of systems I am not familiar with (HV Automation engineer)
Most important thing to have while working on Carrier units= Self Drilling Screws,seems like the doors just never go back on quite right 0r strip out
🤔 they can be dangerous lol, I once lost my vacuum installing a panel 🤦🏻♂️🤦🏻♂️🤦🏻♂️
Thanks for the content!
