I've just got here from a Technology Connections video about swamp coolers.
E: This comment sure blew up.
Ditto I think I saw this video or at least part of it once before because I do want this channel anyways I did not realize they use swamp coolers in combination with cooling systems like this it makes sense to pre-cool I guess you could say theoretically it would increase efficiency you're so carts of the country not where I live but in arid regions and other extremely dry regions swamp coolers can make a big difference although I've got the parts that were originally used for them for other purposes. Like for example the pumps are also blowers and even the switch that would be installed in the wall what's the multiple contacts if I find them so I can get them useful for some projects.
AKA repurpose recycle reduce reuse.
Same! Not gonna lie getting cozy with these videos.
Same
Ditto. I love it when one channel producer links to another channel with more content to enjoy and takes me deeper down the nerd hole. Subscribed.
And thank you Mr. HVACR for producing and sharing this!
Same here. Its pretty interesting. I love finding new channels that are recommended by other youtubers.
I work in software engineering and people think I'm a wizard. I'm watching this video and think you're a wizard. Always great to see industry pros doing their thing. Cheers from one industry to another!
Thanks bud, funny thing I think your a wizard........ doing all this video stuff and trying to setup a website has me pulling my hair out.
@Scott Fitzgerald No... Just no!
Get a professional and do it properly
@@HVACRVIDEOS I'm a farmer and I think you guys are both wizards.
I am playing card right now.....guess what its called......
Yeah, we the programmers just does not works without A.C., simply our brains can't think!. So, is like these videos come attractive for us.
Why is this in my recommend feed? *17 minutes later* Never doubt the algorithm.Never doubt the algorithm.
I don't know why youtube thought I wanted to watch this, I'm so glad I did though
Me either and I'm glad and happy I totally learned something
@freedom or death not sure who you wrote that to but i have been in the HVAC business for about 14 years and with the same company. Its all about who you work for and with. If you have a nice team and work as one big family its awesome.
Fault finding is like a small puzzle
I have NO understanding of anything you said, but this was still cool to watch, thanks!
I recall hooking up a 1/2hp compressor one time with my apprentice . I ran out to the van for something , came back and he had the suction rotolock all done (I was pleased) we vacuumed down , held the “wc drop beautifully, charged , fired it up and suction pressure didn’t move , but compressor sounded like it was in a vacuum , I scratched my head for a min , finally asked , did you pull the rubber plug before hooking up the rotolock ? He said “there’s a plug? “ I had a good laugh ,reclaimed , pulled the roto and there was the factory seal plug 😆 lesson learned !
No idea how this unit had ANY flow , how was this not picked up on day one of commission😳
Whatever you're doing you've figured out the you tube algorithm . In my recommended now I'm binge watching
Thanks bud
Learn a trade, you'll never go hungry.
That is true
I work for food
im getting pretty sick of that happening. starting class in a couple weeks for hvac.
I'm about halfway through my HVAC school training, and I'm at the top of my classes so far. I can hardly wait to start in this trade! My god what a world of opportunity I've discovered.
@freedom or death Winter is bad? Don't people need heating AND cooling?
I work in a chemical plant and have done since brand new commissioning.
About 5 years later a centrifugal pump stops pumping and ended up finding a 3 inch plastic pipe cap stuck in the suction.
It is a clean steam condensate system and that damn cap must have floating around in that tank since new, whoever boxed it up without looking needs a kicking.
A little preventative maintenance would have saved them some money.
That costs money. Companies have a sh**ty habit of blowing things like that off until they're forced to deal with it. Then they pay out and bitch about the budget when things come up about other necessities. Saw it with the company tractors at my last job. Sure enough, they didn't bother with maintenance and the things had all kinds of issues. One had to be cracked in half to have work on the transmission done, which would probably take a few good weeks, meanwhile leaving us with three less-than-capable tractors. I got the hell out before that needed to happen. Not suffering for the sake of the company's incompetence and greed.
To be fair most people are jaded by the constant sales-pitches they have to endure for service contracts and extended warranties with all sorts of costs, hidden fees, and legalese that makes it worthless when you actually need it. That's not necessarily the case here since I think we can trust our local HVAC guy to be fair when doing a yearly checkup, but with other industries it is the case and it's driven a lot of people to just ignore maintenance till it bites them since they don't understand the technology.
I think a good idea for HVAC techs and the like would be to make pamphlets that explain what wears out and why so they can hand them out to commercial customers to easily explain to them with, no pressure, why they might want to consider signing up for regular maintenance checks. It's a lot easier to justify the cost when you understand the value you can get out of it vs just trusting the guy who's making a buck off it that it's necessary.
@@MrMattumbo
Yes with most monthly contracts the service company under performs. Repairs with commercial refrigeration is very expensive. I believe tmresturaunts would do well to train an employee to clean condensor coils, maybe check amperage on motors and check on equipment once or twice a week
@@jpp9876 Yeah if any business, not just resturants, gave valued employees a bit more training and compensation to handle stuff like that they'd save tons of money. A lot of stuff isn't complicated, there's just no incentive to learn how to do it and convince management to let you do it. Restaurants especially would be wise to do it though, a bad walk-in can ruin their day the same way computer problems wreak havoc on other businesses, yet unlike them who have IT guys on staff a restaurant doesn't have anyone with the slightest clue how they work.
I wouldn't recommend sending the busboy up to mess with 3-phase electric stuff but simple maintenance done with safe procedures could avoid the need and spot the problems that need an HVAC tech early. In this case just understanding the function of the swamp cooler and checking that it's running with a thermometer every month probably could've spotted this before it threatened their food stock. I was a cook once and the regulations around keeping your cold stuff cold are strict, if followed properly any serious downtime on the walk-in could force you to throw everything out and cost thousands of dollars.
Talk about an expensive service call. Lol that bill was enormous.
At least 2 grand
For those boxes with the swamp cooler, since it is so crucial to keep those boxes cool to a certain extent, shouldn't there be like a thermometer type sensor in the box and have it display temp near a cooler, or maybe a little indicator light for if it hit a certain temp, the restaurant personnel can contact you before the same problem of overheating killing off the compressors and fan motors.
There are a million different ways to verify that the enclosure is at a certain temp and operating properly. It not having any sort of safeties or monitoring is absolutely bonkers. You could use a donut (small coil that reads amperage, like his hand-held amp-clamp) on the pump or a flowmeter in the pipe for the water flow, a paddle switch for the fan, and a thermocouple in the enclosure, plus a small and probably pretty inexpensive electrical cabinet, and you would be safeguarded against any equipment-murdering failures like this.
GemCat A Doughnut do you mean is CT coil , or current transformer coil
one trick you could have tried to unlock that compressor is the reverse the phases to make it turn the other way ! maybe could have been lucky . but after that red cap shit you did the right thing
Trust me I tried it, along with kicking it, shaking it, and cursing it ........ :-)
Yeah Gecko HVAC, I have done that on semi hermatic's. Had it wok one time on a Saturday walk in box. Never had it work on a reciprocating compressor
@@HeroCaleb I like to think it scares whatever you are cursing at into working!
Andrew Meredith LOL! I never thought of it that way!
HeroCaleb.com
😂 that red cap part
When you place you palm flat on a compressor or grab a copper pipe and it is electrified your muscles in your hand contract, involuntarily, you grab on to that item and your not able to let go, you can easily get electrocuted. If using your back hand, your fingers lock up toward you and not on a compressor per say. I know some can describe it better then me. Have great respect for electricity, it can kill you.
Especially that 480V.
I use my penis
@@Youngbl33zy be sure to use the front side of it so if it contracts it does not bend backwards
Tabatha Creedence lol too much though bro...
Oh indeed, but if you want to do it best and particularly when you're dealing with more than 120 single phase (and especially with this 480V stuff!) is get a non contact voltage tester. Aka a sniffer. A quality brand name one isn't much and will save your ass by knowing if anything is electrified.
Technology connection brought me here
Thanks for watching!!
On a 3 phase compressor that is mechanically stuck, I usually try to reverse the rotation (on a recip). Just to see if it will un stick.
I never really got the chance to do hvac work once I came out of trade school and I can say it inspires me to see your video and to all who are watching I can tell you that this guy is the real deal and his experience shows through his reasonable explanations. Text book trouble shooter great job.
*Technology Connections* sent me!
Yeah there have been a bunch of you today, I sent Alec a message and told him thanks!
Finding that plastic cap internal of the roto lok was hilarious. The company I worked for in Windsor Ontario had installed a new 200 ton chiller on top of a 26 floor condo building. The compressor kept kicking out on high head. The guys assigned to it never found anything out of the ordinary. One night I was on call and ended up there. Compressor off on hi head. I climbed onto the top of the water cooling tower and just happened to notice that about 20% of the branch lines at the end of the main 8" water feed line weren't spraying hardly any water. I shut everything down. Was able to pull a couple of branch line pipes off, reached in and felt around. The { it rhymes with plucking } plumbers that connected the water tower had pushed the plastic pipe shipping cap straight into the main supply line water feeder pipe and it got pushed down to near end of the line. Some times it would be sideways and allow sufficient flow, and sometimes it would turn and block the last 20% of branch lines. Pulled it out. That solved that. And the view from up that high on a nice summer evening was outstanding. Keep up the good work. And stay curious. LOL.
that sounded like it was a good night for you. do you know about how much the bill was?
@@magicarmyman A win is a win, that's for sure. I have no idea what the bill was. It may have all still been a warranty situation? Billing was handled by the office .
@@gadgethunter5732 o.k. still seams like an absurd situation.
Bondy is that you?
@@adamlamb1441 I worked with a Bondy at that company for 10 yrs.
I hit 120 F on top of a walk in freezer today, indoors! Customer doesn't want to add fans or a cut in to the outside to bring the temp down. Just counting the days until the compressor dies. That red cap is so strange but it's moments like that you will remember always. Good repair dude.
Apprentice Phil thanks for watching. Its slowly heating up out here, it was 101 on the roof. Summer is coming
Im a hvac tech, 3 years in the field. great video, so good explanation . Thank you, hope to see more videos.
Great troubleshooting! That red plastic cap inside the suction line service valve was, in affect, serving as a restriction, preventing enough cool suction gas from flowimg over the motor windings in that hermetic compressor. It's a wonder that compressor lasted as long as it did, given that it never had a sufficient amount of motor cooling, even when it was working. Good work!
I appreciate what you do for the industry my friend. Keep it coming is all I’d say fam. Sometimes we need a reminder
Assuming you are doing this to help educate us.....mission accomplished! Last month the algorithm suggested a/c for some reason. I've enjoyed watching.
Last night my compressor stopped, thermal overload. @ 1:00 am I was up checking things and found my capacitor was bad. Thanks to you I was able to figure it out. $26 bucks later I'm up and running. South Florida is not comfortable without a/c.
Very much appreciate the help!
You are my favorite teacher ever
Thank you for your time
Excellent video, very informative in though process in troubleshooting, safety, and logic.
Very well done, keep up the fine work of dedication to the trade and customers
Man you are the best hvac I’ve ever seen in my life overseas or here I fixed my own walking cooler from what I learned from you truly you are a great teacher
I will be going live on TH-cam this evening 8/19/19 @5:pm

Makin that late night saturday service call money. I love it.
I’m just a landfiller but I’m still young and I want to get Into the trades and your videos and others like yours are really helping me make that decision. Thanks for the interesting content!
I am in the HVACR industries and bro your videos are dope.Iam sharping my knowledge right now,I appreciate your tips.Tumbs up plus share nothing but love road warrior.
Cant believe that they didn't make each of those condenser fans blowing out of that enclosure.. Just seems that if the swamp cooler goes, that at least it wouldn't be heating it self out.. Oh now looking at the fan direction, they would have to blow through the condenser instead of suck through. Anyway.. great vid, enjoy seeing an actual professional.
I am hooked. I took a semester of HVAC at my local CC. Mostly for personal enrichment to fix my own stuff, and to use my GI Bill up before I lost it. My eyes were opened when I learned the refirigeration cycle. It’s amazing how many applications that were in use with it. I’m never going to work on a commercial cooler but, Iove watching your process. Your channel is awesome. Keep up the good work.
Thirty four years ago, I installed a ton of these rooftop refrigeration units. I never saw a swamp cooler connected to the rack before. I guess that would only work in low humidity. In my opinion, it's a lot easier to change out a compressor in commercial refrigeration equipment. Replacing a compressor in A/C residential equipment is usually a lot more work.
the moment once the thermal overloads reset and your fingers are crossed as you turn it back on! could be a short service call or a long one!
Whenever i ohm out the windings, i also check them against ground.
Great to see how things are done across the pond
So different
And so the same 😀
I really enjoyed your video. I spent years as the hot/cold tech for a county school system but had to leave due to health issues. I like how thorough you are.
Thanks !
Thanks for taking us along with you
Thanks for taking the time to watch!
@@HVACRVIDEOS It's bloody interesting

Do we get paid
Very clean work
I love this channel helped me out big time I fixed the ac at home works like new now
Currently pursuing bachelor's in electronics, just one of your videos has had me hooked to your channel, great work man, your content goes a long way like literally
✌️🇮🇳
Awesome video and i like how you pay attention to detail. I suppose it's natural due to hundreds of diagnoses known to our trade. Keep it coming. Video was much Appreciated.
Here from TC! I think I’ve found a new channel to follow, I love these really detailed videos about industry specifics. Working in medicine myself, I’ve always been fascinated by other fields and they work they do. Keep up the good work!
Awesome! Thank you!
You nailed that service call. It would be cool to have a thermostat or sensor wired to an alarm of some sort so when that swamp cooler fails to perform they get a heads up to get you out there before they wear out them compressors. Props man !! - Mikey fix it
Perfect! I enjoy learning stuff like this. Thanks for sharing.
Good video, thanks. I use my nitrogen with a 1/4 inch union and my gauges to set pressure controls prior to installing them. This method has also saved my butt a few times when I received faulty control from the supply house.
Great tip thanks!
Just found this channel and hooked on your videos. Its giving me great knowledge i very much appreciate what you do thanks alot.
For some reason these videos satisfy me great job keep the work up
Another great video, thank you for make it. very good and clean job.
I shadowed an hvac job for a day out in riverside (not exactly the same thing but pretty darn close) and I this brings me back to that day. I enjoyed it, too bad I couldn’t see that being my career.
Cool suggested video. I was an electrician for 10 years and I’ve been doing appliances for the last few years. I’m only doing sealed systems with 8oz max. Very interesting to see this.
Love the Trouble shooting , very thorough
I dunno if you mentioned it, but that bit of plastic is common place for compressors and other things that require that the insides stay clean before installation. Someone probably forgot to remove it when they installed it. When the person tightened the fitting, the compression deformed the outer edge lip of the plastic (your shard) and the remaining chunk was able to be broken free from the heat and pressure. Surprising it lasted this long, only probably cause the plastic probably floats in the refrigerant and oil, which allowed it to get past. At least we all not know that this refrigerant doesnt eat plastic!!
Nice video bro. Very informative. Pretty impressive how you document it so well, while also doing so much work. Well done
Thanks bud, it was a long night
Dude you're awesome. Thank you.
when a cooler needs its own cooler
Technology connection sends his regards.
* pew*
Bro you know what’s really tripping me out? How trippy this video is blows my mind. Lol just kidding ya bubba love these videos. I want to do this for work I love this I’m gonna do it get back to it like I was going to do in high school.
Interesting video with multiple problems. Finding the plastic plug was very fortunate. It restricted the passage of cooled refrigerant probably making the compressor run hot for years. Nice way to spend a Saturday night.
Thank you for your time and knowledge great video
Whenever my compressors gets over heated I use a garbage bag with ice to minimize the water spills. Advise from maintenance tech

hey man great videos by the way, i follow a lot of guys on TH-cam but just found your channel . keep em coming 👍
Thanks for the nice words!
Awesome video, I do very little refrigeration...mostly all residential A/C - so watching stuff like this is a big help. Currently deciding whether or not to make the jump to a little bit bigger company that does equal amounts of residential, commercial, and refrigeration...I've kinda plateau'd on my learning curve where I'm at and am the most experience technician(with only 3 summers in the business).
Where do you live?
I worked for a very, very small resi shop straight out of school and learned nothing. When I went to work for a small, high volume commercial company I learned tons! Things I never even dreamed I would end up working on....mostly commercial restaurant equipment. OK, a LOT of restaurant equipment. Best career move I made. went back to a resi shop for a very, very short time and realized that I hated it.
Commercial refrigeration is where I learned the most. I now own a small (3 techs) company and do mostly refrigerated warehouses and supermarket equipment. If you're looking for a challenge, the big stuff is where it's at.
long night but big buck was made pretty sure... getting into the business and so far loving this job
This is so cool I know exactly where this happened. I live literally like 15mins away from here
I learned a lot watching this. Great video, thanks for sharing.
Thanks, I try to share as much knowledge as I can without becoming a DIY TH-cam channel!
Thanks. For your videos. They teach a lot
I used to always do a suction line filter change after about a week of running when you have a compressor burn out. So when you change out the compressor put some isolation valves on it so you dont have to recover to change it out... I realize that your ohm readings were good and nothing to ground like a burn out but with that much warranty exposure it's very good insurance - you dont want to be called back in 10 months with another burnout.
Good repair dude
Very informative.I lost 100 litre ice cream last week due to my irinox freezer stop cooling ,not going below 15.
Your Work is awesome I enjoy your video's it's amzing the stuff you find
Thanks bud
Love your videos brother! Have about 12 years in the trade but not much in Refrigeration aspect of it. Taking courses at my local union hall for refrigeration I don’t care about the late service calls as long as I’m working for myself lol
Right on thanks for the nice words bud!
Great job!
Enjoyed the video man! Keep up the great work!
Thanks!
That's a first for me, I have never seen anything like that stuck in a system for that long. That was unbelievable, nice job.
It blew my mind, that unit was installed in 2012.
ive done plenty of those and i didnt mind it working at night
this guy is frggin awesome!
Hahaha sombody left the cap inside the copper when installing
After four years I just switched from residential to comercial about a week ago , I like watching your videos but I’m really nervous every time I go to a service call, hopefully I can catch up fast
That red thing looks like a bottle cap! 😂😂😂😂
My preferred way to cool off a compressor (and make less of a mess) is to use bags of ice. Lay on on top and maybe around the can itself if possible.
Thanks for watching I am going to do a live stream on my channel tonight at 5:00PM pacific time come on over and check it out th-cam.com/video/xXqmXSiLch8/w-d-xo.html
While ice does make less of a mess and if that is a concern ice is the best way to go, using a steady stream of water will carry more heat away in the same amount of time.
Water always worked well for me.
10-1 that red plastic plug was left in there from day one...amazing how it ran as long as it did
good job Sar
Sir I proud of your job I like your job sir can I attend your job and your company please tell me I want to join your job and you company please I am from Bangladesh and I am normal technician me but I think I can do better please forgive me turns I want to job with you thank you sir
the first time I opened up a line set and blew it out my guy on the other end got some large copper shards he was one impressed rookie and I was amazed!
I barely know anything about HVAC but I find this fascinating. gained a sub today :)
Excellent video. I'm not in that line of work but it was a nice ride along ! Thanks ✌
Right on thanks for watching
Great video! I use your videos as assignments for my students. Hopefully they will see the value in it one day. Nice job!

Yep i try and read and like everyone, I dont always get to answer them all but I try to respond to as many as possible!
Nice repair video
Wow small world. I was the chief engineer at the doubletree in cat city. The rack we had was tied into our chill water loop. Our biggest scare was our chillers going down and the rack heating the chill water loop and blowing the high pressure rupture disc on
R11 CVHE chiller. There’s some weird stuff out in the Coachella Valley. Hey did you know fantasy springs casino purchase a hi speed chiller that was salvaged on the first trade center bombing. I think they fire it up when temps get over 110s. Hey I enjoy your vids. Keep it up.
The installer missed that tube plug during installation. I was a QEM manufacture and the condensing unit a lot of times comes loose and in a bag. I also weld the valve with it off the compressor to keep the heat down. Premature compressor failure would be expected.
great advice ! thanks for taking the time to comment on my video!

till the owner gets the bill
@@tom-dr1ym To throw away Food from the freezer costs alot more; maintenance and repairs are calculated anyway in our yearly budget.
LOL Until you get the invoice. Then we are overcharging jerks right
When you check out the compress motor you should also use a megger to meg the motor to ground. This will check out the motor for windings grounding out. A 1,000 volt megger is the recommend type to use these days, especially if you have any compressors or fan motors that run off a VFD.
Good job Buddy, but the reality is the Evap cooler should be in front of all the condensors, there was enough room in front on that install, and louvers at the rear of the units..the guy who forgot that red plastic cap was sloppy...have had similar stuff over here in australia..
