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.

Use to do work on a big day care out here in az they change their filters once a year thats all they ever got a call saying there units wasn't working 20 out of 23 units with belts completely shredded 3 about to break 3 units with grounded compressors two outdoor motors seized and and a unit with a restriction and one with a refrigerant leak and asked if I could do a full pm change filters and belts and do all repairs in 2 days
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.
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!
@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.

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.

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.
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
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 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.
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.
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
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!
That would be a good training session for a newbie if time was on your side. I'm noticing that I can watch these videos now and I'm starting to pick up on what is going on and what to check. Thank you for teaching me how to fix hvacr.
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? ^^
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.

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.
I'm going to be honest with you.....the wiring layout is shocking (no pun intended), no proper runs or management, a real rats nest, my professional ocd radar is off the scale....used to rewire fast jets. Power, signal, data, comms etc all have separate cable trees/runs, far more ocd than the real uber custom pc builders. Zip ties are specially made so the smooth surface is against the harness, cable lacing etc..... loved it. So I see that rat nest of cables and all I want to do is tidy it up, harness it all up nice and tidy......
Every time I see I thing like that all I want to do is to chop away those wires and rewire all using proper conduits. Here in Europe is completely illegal to have cables and wires like that.
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
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.
Can’t stand a customer like this. They won’t spend hundreds to prevent the thousands later. As a technician, it’s tough to see things in shambles like that and not be able to fix it. I’m a commercial tech in a poor state. Not a lot of customers want to do replacements over repairs. And some won’t even do the repairs.
I wish I was you, you know everything. I just started working at Wendy's i don't know if you have Wendy's restaurant in California, but in Illinois there's a bunch, and as a facilities maintenance technician we have to repair kitchen equipment. Fryers, walk in freezers and cooler', and ice makers and pm's on top of that and there's only 3 of us in Illinois, I was just hired. I used to work on residential appliances not commercial. I love your videos. Please make more ice machine and door replacement videos.
Actually that's not true. Warped Preceptions did a video on which is quicker, the breaker or a fuse. The fuse was much faster. With a direct short that is.
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.
@@blueoval250 early versions were based on rasperrry pi. They make their own hardware now. I’ve been a loyal installer as they backed me while I lived in Portland and when I moved to Montana they had my back at every turn. After ecxpeiencing their stellar installer support and how well their systems run and never generate calls unless people want more media or more doors added, I won’t ever switch.
At 7:30 or so, we see the typical bad work done by the 80% whose previous job included asking the question, "would you like fries with that?" Bad work by others keeps you and me busy. Also, you mentioned that your area has problems with the electrical grid. This means that when a phase leg becomes de-energized, you can open a breaker when the other two phase currents increase. If a unit is running, a phase loss will open a breaker very predictably. Units where power is a problem will often get an ICM450.
Dude Ill have to recommend you. i live in corona. I do IT work for and have clients with Commercial buildings and they can never seem to find people who can do the job right! How far out will you go from Mira Loma?
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
It never ceases to amaze me that customers want something fixed but do not want to pay for the fix and/or want to cut corners to do the bare minimum to get it up and running again. They never look at the long term costs associated with doing that and short term gain. If you just spend the money upfront, you gain so much longevity!
10:04 is it just me or some crappy wiring on that ac, wiring sticking out of the fan guard lol. Man i feel sorry for you Chris fixing other peoples mess.
So i have a non HVAC question ive been trying to get answered, while its not your field i was hoping someone could answer since electrical work is common.. So when my house was built there were a number of outlets that instead of installing GFCI receptacles they made it so the GFCI is handled by the breaker, would adding an actual GFCI receptacle cause any issues with the breaker portion thats supposed to be handling it?
@@DigitalIP I know you can’t have gfci in series as they will mess with each other from what I remember. But if you have a gfci further up the line and all the outlets are connected in series off that one it will still protect you
Are you sure it is a GFCI breaker? They exist but code usually has AFCI at the breaker. They perform two separate functions. They also make dual function breakers. It'd make sense to have AFCI breaker and GFCI at the first receptacle.
LOL "condensates" is not the word it's "condenses".... Not that it matters. I'm just a plumber, I just work on boilers... LOL, but "condensates" would be you have multiple AC "condensates" but a unit "condenses"...
I have to admit. I've been in the HVAC trade for 35 yrs now. And I've honestly never seen it done in HVAC. I've only heard the Term Double Flare. You can definitely tell the difference in the Meatiness of the Double Flare vs Single. Only thing is that if you have a bunch of Flares to do it would take you alot more time to do. But if you do singles properly they won't leak either. Properly I said! Lol
I love watching these vids, relaxing tho I dont work in that industry.. Thooo, from a diff country where things are different but seeing cables "floating" in the air is making my eyes burn, is there never used trunking inside the AC to keep the cables safe/tidy ?
Why? The motor may have taken a hit and will be weakened. Also more money on a replacement and the fact replacing will give the customer security knowing the fan won’t fail in a few weeks.
Bro! Do yourself a huge favor. Go get some Zep spray bottles. You're killing your hands and wasting product. Plus your coverage will be greater with the adjustable valve. I've had one for like 5 years. Got mine at Autozone. Actually I have four now. lol.
Do those ACs get built this way? A box with wires just thrown in there, zero f's given? Metal enclosure? Great, let's run the cables without any isolation across the frame, so when the fan vibrations eventually chew through the jacket we have a murder weapon. Yayyyyy. But I have no idea what I'm talking about, so I might be dead wrong and this is done for ease of maintenance and potential threats are mitigated by *insert nifty technical dohicky here*. Anyhow - super nice to see someone who knows these things in and out doing his thing!
Wouldn't it just be better for buildings to just have a central, big, HVAC for the building instead of distributed boxes? Those HVAC forests on-top of buildings look crazy!
Hi wich new package i go with r22 or 410 for good cooling , i live in kuwait the temperature in summer reach 130 Fahrenheit ..? Not: in my country still they sell case r22 package.
Kinda surreal watching this in June 2021 now that a lot of the Country has opened back up for the third (hopefully final) time where I am at, and like he was mentioning, a lot of the businesses didn't make it.. pretty sad...
What is up with that pulley? I have experience with pulleys in all kinds of other industries and a pulley wearing out is not a thing. I've literally dealt with pulleys over 100 years old. Is this planned obsolescence or something? I have also not dealt with adjusting a pulley. I mean I have adjusted a pulley as far as tension and alignment, but not making changes internally to the pulley itself. I am confused.
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.
All the dead units did not happen on the same day, and after lack of care on everything is when I would start questioning am I going to get paid to work on these units. Maybe a bad stereo type but it would run across my mind. Do you get paid before fixing units, tough call here I have worked for so many builders that it makes you not trust anymore.
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.
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.
Core max valves are garbage... it seems as though the engineers behind all ac units are intentionally designing these units with crap components so they keep their jobs by always having something to improve and fix on the next model...
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.
This channel is great I’m a second year apprentice for a union hvac contractor and the mechanical problems units have I can figure out no problem but the electrical and controls is what has always thrown me and have yet to fully understand but videos like this are really helping building my confidence ... you gained a subscriber keep yup the work
You don’t need cleaner? It was filthy? I know that you knew that their AC systems needed to be cleaned out because they were not doing preventative maintenance.
Electrical Code Violation, can't put anything within 3 feet directly in front of any panel. We have an 1200 amp Automatic Transfer Switch in one of our sites that sits adjacent to the main disconnect at a right angle. The ATS has a fold down handle on the manual operating lever. Due to space constraints, if the lever is left up, we're in violation, if you fold it down, we aren't, because about 1" of the length of the handle would be in front of the edge of the disconnect.
Oh man I can't tell ya how happy I am that I found ya again and subbed. Im pretty sure RUclips unsubbed me. But man I have missed relaxing and watching your videos. Just know you are part of my daily routine buddy. Thanks for being a bad ass HVAC serviceman
These units seem very poorly designed...just a rats nest for wiring, no way to properly clean the coils, and when you do clean them there is nowhere for the crap inside to drain off and away. I hope newer units are better designed.
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.
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
Whomever replaced the condenser fan did a bad job, those wires originally had a plastic sleeve that they through away so the zip tied the wires to the grill
Found a lot of blower panel insulation would suck into blower restricting airflow causing unit to ice up and cause lock out on EVAP freeze stat lock out
why did you just repair the wires on the first unit where the fan chopped the wires up. unless i missed something else wouldnt the wire repair be the cheapest option for them?

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.
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
Definitely need to see how you adjust a pulley
Let me guess... Poor maintenance, major neglect, rules not followed, let's see if I'm right 😂
Can’t stand a customer like this. They won’t spend hundreds to prevent the thousands later. As a technician, it’s tough to see things in shambles like that and not be able to fix it. I’m a commercial tech in a poor state. Not a lot of customers want to do replacements over repairs. And some won’t even do the repairs.
I wish I was you, you know everything. I just started working at Wendy's i don't know if you have Wendy's restaurant in California, but in Illinois there's a bunch, and as a facilities maintenance technician we have to repair kitchen equipment. Fryers, walk in freezers and cooler', and ice makers and pm's on top of that and there's only 3 of us in Illinois, I was just hired. I used to work on residential appliances not commercial. I love your videos. Please make more ice machine and door replacement videos.
“ hurry “. Hahaha invoice printer go brrrrrrrrrrrrrr
25:23 “A bunch of SHTUFF is getting sucked into here” haha
Amazing what this guy does with one hand
Love watching skilled tradesmen work
Breakers will trip quicker than fuses! Haven't seen electrics like this since the 70s!!!
Actually that's not true. Warped Preceptions did a video on which is quicker, the breaker or a fuse. The fuse was much faster. With a direct short that is.
What a hot mess this location is.
Classic case of pay me now or pay me later. In the future, it's gonna cost more money.
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.
Favorite access brand? I prefer Hirsch.
@@blueoval250 ProDataKey all day, every day.
@@drue6360 never worked on it. Mercury hardware?
@@blueoval250 early versions were based on rasperrry pi. They make their own hardware now. I’ve been a loyal installer as they backed me while I lived in Portland and when I moved to Montana they had my back at every turn. After ecxpeiencing their stellar installer support and how well their systems run and never generate calls unless people want more media or more doors added, I won’t ever switch.
Man those units need some love.
At 7:30 or so, we see the typical bad work done by the 80% whose previous job included asking the question, "would you like fries with that?" Bad work by others keeps you and me busy.
Also, you mentioned that your area has problems with the electrical grid. This means that when a phase leg becomes de-energized, you can open a breaker when the other two phase currents increase. If a unit is running, a phase loss will open a breaker very predictably. Units where power is a problem will often get an ICM450.
Dude Ill have to recommend you. i live in corona. I do IT work for and have clients with Commercial buildings and they can never seem to find people who can do the job right! How far out will you go from Mira Loma?
Oh s*** every ac?
Edit: Lol I love the “hurry” in the title
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
It never ceases to amaze me that customers want something fixed but do not want to pay for the fix and/or want to cut corners to do the bare minimum to get it up and running again. They never look at the long term costs associated with doing that and short term gain. If you just spend the money upfront, you gain so much longevity!
Welcome to another episode of...........WTF WHy IS YOUTUUUUUBE RECOMMENDING ME THIS! good vid tho
10:04 is it just me or some crappy wiring on that ac, wiring sticking out of the fan guard lol. Man i feel sorry for you Chris fixing other peoples mess.
So i have a non HVAC question ive been trying to get answered, while its not your field i was hoping someone could answer since electrical work is common..
So when my house was built there were a number of outlets that instead of installing GFCI receptacles they made it so the GFCI is handled by the breaker, would adding an actual GFCI receptacle cause any issues with the breaker portion thats supposed to be handling it?
It should work but there is no guarantee that receptacle GFCI would trip first, even both of them could trip at the same time.
Nope, that would not cause any issues. Perfectly fine to do. Breaker will act as a standard breaker at that point
Sweet, thanks guys
@@DigitalIP I know you can’t have gfci in series as they will mess with each other from what I remember. But if you have a gfci further up the line and all the outlets are connected in series off that one it will still protect you
Are you sure it is a GFCI breaker? They exist but code usually has AFCI at the breaker. They perform two separate functions. They also make dual function breakers.
It'd make sense to have AFCI breaker and GFCI at the first receptacle.
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 🤦🏻♂️🤦🏻♂️🤦🏻♂️
Blimey Chris you had your work cut out there? Nice job on getting them up and running? Keep safe dude
10:40 - aaaaannd it just satisfied...
Sir, your unit is broken but, it's working.
As Steve Lav would say: "It's a shit show, mamma."
That was a lot of electrical spaghetti in those units
I have some customers like this one who have crocodile arms. A person can only do what the customer will pay for
LOL "condensates" is not the word it's "condenses".... Not that it matters. I'm just a plumber, I just work on boilers... LOL, but "condensates" would be you have multiple AC "condensates" but a unit "condenses"...
I ran into a service call with multiple units down on a commercial building and turned out to be the good old smoke detector tripped several rtus
I have to admit. I've been in the HVAC trade for 35 yrs now. And I've honestly never seen it done in HVAC. I've only heard the Term Double Flare. You can definitely tell the difference in the Meatiness of the Double Flare vs Single. Only thing is that if you have a bunch of Flares to do it would take you alot more time to do. But if you do singles properly they won't leak either. Properly I said! Lol
That is terrible wiring... How is this even acceptable? In the EU the electrician would've gotten fined for such a shitty job.
I love watching these vids, relaxing tho I dont work in that industry..
Thooo, from a diff country where things are different but seeing cables "floating" in the air is making my eyes burn, is there never used trunking inside the AC to keep the cables safe/tidy ?
Wow : Big job, could you have re-wired the condenser fan that had broken wires instead of replace it??? Thanks for the video.
He sure could. Would he for warranty or liability reasons? I doubt it! Nothing is wrong with the motor itself.
Why? The motor may have taken a hit and will be weakened. Also more money on a replacement and the fact replacing will give the customer security knowing the fan won’t fail in a few weeks.
Bro! Do yourself a huge favor. Go get some Zep spray bottles. You're killing your hands and wasting product. Plus your coverage will be greater with the adjustable valve. I've had one for like 5 years. Got mine at Autozone. Actually I have four now. lol.
Do those ACs get built this way? A box with wires just thrown in there, zero f's given? Metal enclosure? Great, let's run the cables without any isolation across the frame, so when the fan vibrations eventually chew through the jacket we have a murder weapon. Yayyyyy. But I have no idea what I'm talking about, so I might be dead wrong and this is done for ease of maintenance and potential threats are mitigated by *insert nifty technical dohicky here*.
Anyhow - super nice to see someone who knows these things in and out doing his thing!
Wouldn't it just be better for buildings to just have a central, big, HVAC for the building instead of distributed boxes? Those HVAC forests on-top of buildings look crazy!

Hi wich new package i go with r22 or 410 for good cooling , i live in kuwait the temperature in summer reach 130 Fahrenheit ..?
Not: in my country still they sell case r22 package.
Nice Video 👌🏼 Looks like there’s some money to be spent on that site !!!
Kinda surreal watching this in June 2021 now that a lot of the Country has opened back up for the third (hopefully final) time where I am at, and like he was mentioning, a lot of the businesses didn't make it.. pretty sad...
What is up with that pulley? I have experience with pulleys in all kinds of other industries and a pulley wearing out is not a thing. I've literally dealt with pulleys over 100 years old. Is this planned obsolescence or something? I have also not dealt with adjusting a pulley. I mean I have adjusted a pulley as far as tension and alignment, but not making changes internally to the pulley itself. I am confused.
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.
All the dead units did not happen on the same day, and after lack of care on everything is when I would start questioning am I going to get paid to work on these units. Maybe a bad stereo type but it would run across my mind. Do you get paid before fixing units, tough call here I have worked for so many builders that it makes you not trust anymore.
8:48 - yikes! That's a weird mounting of the pressure switches. Seems like that would be very sensitive to vibration and metal fatigue.
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.
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.
Core max valves are garbage... it seems as though the engineers behind all ac units are intentionally designing these units with crap components so they keep their jobs by always having something to improve and fix on the next model...
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.
This channel is great I’m a second year apprentice for a union hvac contractor and the mechanical problems units have I can figure out no problem but the electrical and controls is what has always thrown me and have yet to fully understand but videos like this are really helping building my confidence ... you gained a subscriber keep yup the work
I got to put the cover on my A/C cant use it till april it's to cold. Those coils are nasty looking!
You don’t need cleaner? It was filthy?
I know that you knew that their AC systems needed to be cleaned out because they were not doing preventative maintenance.
And I am just an electrician
Buddy, don’t sell yourself short, if they are not doing preventative maintenance, you have every right to charge for cleaning.
Oh yeah lets just pile boxes infront of the main breaker panel.. good deal. NOT.
Electrical Code Violation, can't put anything within 3 feet directly in front of any panel. We have an 1200 amp Automatic Transfer Switch in one of our sites that sits adjacent to the main disconnect at a right angle. The ATS has a fold down handle on the manual operating lever. Due to space constraints, if the lever is left up, we're in violation, if you fold it down, we aren't, because about 1" of the length of the handle would be in front of the edge of the disconnect.
Oh man I can't tell ya how happy I am that I found ya again and subbed. Im pretty sure RUclips unsubbed me. But man I have missed relaxing and watching your videos. Just know you are part of my daily routine buddy. Thanks for being a bad ass HVAC serviceman
These units seem very poorly designed...just a rats nest for wiring, no way to properly clean the coils, and when you do clean them there is nowhere for the crap inside to drain off and away. I hope newer units are better designed.
Commercial tech here. It's my day off and what am I doing? 6am and watching another tech work.
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.
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
Ball joint separator fork tool. Surprised you don't have a tach for setting pulleys. Good videos!
Apparently those Scroll compressors are complete junk. I’m surprised it even lasted that long.
Whomever replaced the condenser fan did a bad job, those wires originally had a plastic sleeve that they through away so the zip tied the wires to the grill
Found a lot of blower panel insulation would suck into blower restricting airflow causing unit to ice up and cause lock out on EVAP freeze stat lock out
when you are struggling to find cash to pay off the wait staffs and suppliers, AC repairs is the last thing on your mind.
It's all in the plan! #Ruin
You have to watch what you do on camera R22 is supposed to be charged as vapor Maybe I'm Wrong
the cable management in there is worse than mine in my own private self built computer stuff
how do you do anything that messily
why did you just repair the wires on the first unit where the fan chopped the wires up. unless i missed something else wouldnt the wire repair be the cheapest option for them?
