- เผยแพร่เมื่อ 14 ธ.ค. 2022
- This was filmed all the way back in July of 2022 , but the customer called panicked because the kitchen was too hot. Now the call didn't turn out quite like I wanted to but it all worked out in the end.

hi from italy, 27 hrs old learning from you every day, my dad is a 50 yrs old hvac tech but not very good at explain things, he just want the job done fast and he do all by himself, watching your content was mindblowing becouse now i feel confident go trough calls with my dad and understund what is doing and i allready do calls by my self! he cant belive i learned what i was missing from you on youtube, he doesnt speak english so cant understund how deep your explantion are! now im doing call by my self and he is watching (carefully hehe) and now im realy proud of my self! cant wait to learn more! i'm struggling with understund pressure on different hvac unit when i have to do charge, here in italy we dont have any help by manufactures and they keep all data secret, maybe an Advice on that??
;-) 28hrs old :-*
There is software like the one he is using that you can put in basic system specifications and it will tell you what the pressures are supposed to be. They aren’t always 100% correct so experience will probably be your best friend. Also your english is pretty good, i have friends who moved to America years ago and they still can’t write in a way that i understand.
What part of Italy
@@chrisb945 not cool bro 🙄🙄😒
@@LostDeadSoul As a ret. Chemist with a year in van and 608, the big deal for these guys is temp/pressure plot for each refrigerant. The Thermodynamics part is more useful "comfort" via dew point and moist vs. dry air, latent vs. sensible heat. This is where air flow vs. relative humidity is determined.
If I end up moving to Vegas, I'll be hitting you up on how to stay cool on roofs. Anchorage to Vegas is quite a change.
Thank you for posting these videos. As a parent of a teens and a Boy Scout leader I have shown your videos to numerous high school age kids to educate them on the opportunities and benefits of going into a trade profession. I appreciate how you show your troubleshooting logic,honesty, integrity, customer service philosophy and work ethic. Your videos have made an impact on people far beyond what you might be aware of and I wanted to know you are making a difference in people’s lives.
Thanks so much I'd really like to find a way to be involved in some sort of youth education for the trades
@@HVACRVIDEOS Keep up the good videos brother, I’m a Field Training Supervisor For Level 9 HVAC and I have definitely encouraged our guys to check out your channel Several times due to the way you explain things. You are definitely a wealth of knowledge and would be excellent at doing anything involving the development and training of young techs.
just graduated technician school, thank you for your educational videos!
Also looking at the dirt patern you can see the dead fan had been out for a while, because its output grill was cleaner than the others.
When I was a mechanical consultant I was called to a restaurant as air con coy was servicing he units and was having on going problems. They had cleaned the condenser coil however when I tested the air flow over the condenser coil it was like a jet engine going in the middle and less as I move out to sides. Due to issues with location of kitchen exhaust and ongoing problems we had a condensing unit install in a clean area of roof turn the system into a split. The original design of fine until they add a second storey derive thru and a multi storey building went up next door which made a dead area for air flow around the unit. This is what you would call a strange big picture issues
107 outside, the reason I only did inside refers. I'm not working in the sun when it's that hot! Good job, love your videos.
I admire anyone who can work in that heat and not complain!
Thank goodness that the pressure switches work normally and that there’s a lock out! Many a micro channel coils leak from failed pressure switches and dirty coil combo, or condenser fan motor failure for that matter. Great video as always!
Those restaurant units are good job security. They don’t maintain them. Good job on those videos.
Thank you Chris your videos are awesome and the only thing that worth watching..your a great teacher. Your father should be extremely proud.
when i was working man i would love calls like this, it's your 5th call of the day, your about worn out, it takes you an hour to find a hose bib and connect your hose, the hose pressure i next to nothing, ,but you clean the condenser, then you find out one condenser motor bad,maybe the belt worn out, the first stage about out of refrigerant, you get things running and your boss asks you if you can run one more call lol
I own a heating and air company in Oklahoma. Love watching your videos keep up the good work brother.
What part of Oklahoma are you in . I also have a company ...SE OK SW AR area for me
"It's what the desert does to ya"
.......The Coachella Valley Desert? Lol
"This customer does not do routine maintenance" So basically like all your customers haha.
They may have to put deflectors on those exhaust fans to keep the effluent off of the units.
Good thing you didn’t need a new blade… Last time I had to get a new blade for a fairly new York unit the set screw was loose and the blade fell down and got screwed up. Anyway got all OEM stuff got up there to install it and the hub of the blade was on the other side. I called the supply house and he stated last time they had this issue the engineers at the factory claimed it was a engineering “improvement”. Or as he said they got that blade cheaper 🙄. Keep in mind the main warehouse for York parts is just 10-15 miles and the unit was built 3 hours south of us. We see a lot of York…
Damn that sucked
Must be nice having machinery that diagnoses itself. As an industrial maintenance tech/mechanic I would love some error codes.
I'm from India and learning a lot from ur videos
Me seeing the thumbnail:oh no not this heap again!
09:00 this motor💀
11:32 the condenser cleaning door 💀
Edit: it's crazy of how warm it is near there but how cold it is near me
But great job on the videos keep up the great work. I have watched every single one of your videos since it started there awesome 😎
I love your videos. As a kitchen manager I have learned so many "dont do this" things just from listening to the things you say causes issues in the units. Great content keep up the great work too.
I haven't been in the industry in a while (i was a manger that ran a three shift restaurant that cooked no frozen food) but i can help you in one way. Always keep cleanliness as rule #1. If it takes 5 extra minutes to wipe something down, that hours later will cause a mess to drip onto something and kills your equipment. In my old restaurant water with small amounts of bleach were kept at all stations and everything wiped constantly. All fryers and grills were cleaned twice a day and also wiped constantly. Grill vents were cleaned once a week and Everything else either every two weeks or once a month. It does make a difference and i was never embarrassed to have a customer to come in and look over the kitchen. (yes i had a customer who claimed we kept a nasty kitchen. I brought him and his wife into the kitchen and set them loose, no one followed or said anything. When they were done the wife said that the kitchen was cleaner than hers)
Hello, Chris, I was thinking of you yesterday when I was taking parts off of a Federal cold prep unit. I got two led tube fixtures and two additional tubes from two different units, plus two Carel temperature controllers with only one thermister, for a possible project. I'm also looking at two frames fro prep tables I may use in my shop for a quick workbench. The lights will be used in my shop, as I have to use a generator on the farm my shop is on.
If you're using a generator, even if it's a proper inverter generator, I'd strongly suggest you add either a large UPS, or at least a good sized true inverter (line conditioner) for your (non-incandescent) lights and electronics. You can get a 1200 watt APC LE1200 for under $85, and a TrippLite unit for under $200. Clean power makes for happy LED, fluorescents, computers, and other electronics. Motors and incandescent lights don't care so much.
Excellent as always Chris. Happy holidays to you and your family as well.
always crazy how entertaining your videos are.
Anyone who puts those back screws back on a York is evil lol those should be considered shipping screws only and once in place permanently removed.
Thanks Chris... Merry Christmas
Great video brother. I love that you show the right way to do things even if it’s something small. Sadly a lot of guys don’t know you don’t have to use both those brown cap wires with 3-4 wire setups. Your kicking ass bro on the channel so happy for you my man.
Thank U for the time U take to explain things in detail, not easy when u are working. God Bless look forward to your videos.
Really interesting information given away for free, nice job!
I love your channel I wish I could work with you I appreciate the effort you take to make your customers systems better 😊
Don't even get me started on microchannel coils near those grease fans 😆
Good job amigo,Happy Holidays 🎉
Love these videos!
Merry Christmas to you and yours
Chris once again great video brother good to see you’re still staying busy, we’ve slowed down here in the Dc, Maryland, Virginia area man
Stay safe brother
Happy Holidays to you and your Family Chris! Always great content it's why I keep coming back. 👍
Thank You , Very Much !
Great video. Thanks.
A complex and complicated background is often a selling point for a discussion video, though you DO have to occasionally make a video explaining everything in the background for new people.
Watched from beginning to end ! Hope my TH-cam premium helps the recommended 👍🏾
HVACR is the cats-ass TH-cam channel of the HVAC community!
Another excellent video
One of the many kitchens I work in now has one singular problem. The heat. When it’s under 40 outside and the heat is on. It way overshoots. Gets to 68. Then continues going till it’s 100.
AIR CONDITIONED KITCHEN - *WOW*
Down under its a case of
"If you can't stand the heat - stay out of the kitchen"
I worked in a hospital kitchen that had no a/c back in the early '80's and I know about heat,sometimes in the summer the kitchen got to 100 degrees and higher so we learned how to keep everything as cool as possible by having lots of fan's and keeping the kitchen cool by doing cold lunches and dinners for the patients
🤘👌🤌👊👏......nicely done as always Chris
York uggggh lol great video chris
I bet there is an exhaust from the kitchen in a bad spot up there and that crap gets sucked up and sticks to everything
ABC, air flow before charge.
LOVE THE CHANNEL! I live in central Fla. Orlando. Code here is Ex fans need to be 4 feet above cond. fan blade within so many feet.
What’s up fellow central Floridaian! I’m from Cocoa and am a service manager at a company over here. His videos are awesome, and when I watch some other videos from other guys I always compare them to Chris lol, he’s way better than a lot of the other ones I watch. Keep on keeping on in the AC world buddy! Drink lots of water and wear a sun hat! Lol
Those units are the hardest to clean, the inner coils are always neglected
Not able to proper air cooling to subcool hot gas coming out of compressor. Great video
If you use the liquid that’s used in dishwashers to make the dishes dry with no spots the water will not stick together on the coil you are cleaning. It might be called dry soft . Just try it and let me know how much you like it. Love the videos
Hvac 💪⚒️
Hey great videos you are a knowledgeable man, I specialize in commercial ice machine repair,(only)I'm trying to get my c38 I passed my law exam but I'm having trouble with the trade exam because the exam covers walk in cooler, cooling towers, and commercial refrigeration installation and service which I don't do, I was wondering if you could send me some basic info to help me pass the test 😊?
Nice 4090
“Surface tension”. ;-)
Dirty compressor coil dirty, not releasing the heat.
Because the compressor can't dissipate heat because of the clogged condenser. Also clean your outside unit frequently, AC using people!
dirty condenser i think means that the airflow is not good enough to get rid of the heat so the pressure goes up and eventually stops the unit.
you can get that with home whole house and window units.
if you cant get an oem motor you could use the remaining fan and just tell them not to push the unit too hard.
You get calls on those units because they're York's, and junk.
Why not fit taller exhaust hoods?
It would nice and useful if you could remind us of what Subcooling and Superheat is. You are a professional but I am not. In my day it was called Delta T across the Evap coil, Condenser coil or whatever. Terminology is important.
Just a suggestion not criticizing. It just seems odd you go into great detail on how to clean a condenser coil but rarely impart Refrigeration Nomenclature explanations especially when reading and analyzing your guages. I realize this is not an educational series, although it is close. I think just a few more terms for us old folks, as well as Rookies, would help.
I wonder why these units can't have a feature where the condenser fan motors can reverse for a minute or 2 to be able to blow the dust and debris off of the fins as much as possible. Some farm tractors and combines have cooling fans that can reverse themselves to blow the dust and debris off of the filter screens and radiators so the farmer doesn't constantly stop to clean them. It seems to me that these could do the same thing with a sensor that senses a lower airflow so that it reverses the fans for a few minutes to try and blow some of the debris buildup off and then can go back to normal operation afterwards.
So on Predators I do condenser motors in 2's. That motor close to the blower motor door was replaced. Was only a matter of time that other motor failed.
Are there any surface treatments for condensers expected to be in greasy environments? Some sort of spray on oleophobic spray, similar to water repellants like Scotchguard?
Chris do you have any units with the se board,not a lot of info on it.thanks for the vids.
Have you ever taken the old factory motors out and had them rewound and upgraded brushes added? Even if you did it for commonly used motors, you might have a spare ready to go. I believe a rewound used motor is better than any new chinese motor.
I will discuss this on my livestream this evening 7/24/23 @ 5:PM (pacific) come over and check it out th-cam.com/users/livevuts2K8DmCM
Quick question: since the yellow viper cleaner is safe on aluminum, could you just use that for all of your condenser cleanings just to be safe?
8:25 surface tension LOL
It's hard to get worse junk than a modern York. Microchannel coils? It looked good on paper. Can you say "transition joint?" I knew you could.....
If the outdoor temp is 107. Can you even trust subcooling to diagnose anything?
OMG I hate york predator units especially the newer ones
Why not get a removable wall installed between condenser coil and exhaust fans?
12:32 Will having that clean out door flapping around in the breeze affect the performance?
It's not working cause it's a York.
What would be the most cost-effective way to mitigate the problem from that greasy exhaust?
Do you ever use uber for delivering parts? It is one of their services they offer on their app. It takes a little more coordination. Your vendor has to bring the package out to the driver because the driver won't typically go inside the business. Then you have to be waiting for the driver at the other end. But you can track it all on the app. It can save you a lot of time running to get a part.
Condenser pressure increases with a dirty condenser because although your heat absorption (evaporator) is still absorbing heat normally, and your compressor heat of compression hasnt changed much, the system becomes "heat soaked" due to lack of heat rejection through the condenser. Your refrigerant flow will try to increase due to pressure differential accross the metering device but the liquid will back up and build up pressure. Since the condenser is a saturated volume, your saturation pressure will rise, not just the temperature.
Not necessarily the liquid will be backed up. In fact you will have less liquid because the refrigerant will remain in more of a gas state because it's not rejecting heat thus becoming a liquid. So in reality tour txv will be starving or in other words you won't have a full column of liquid.
@@dcmarvelunited5529 I dont agree that the metering device would starve, the quantity of refrigerant has not been changed only the effectiveness of the condenser. You will definitely still have some liquid at the valve as proof of your subcooling measurement. You may have less liquid being formed and more refer trapped as vapour, but I still believe the theory that the liquid present will have a much greater force exerted on it, altering the flow rate through the valve which can raise the evaporator sat pressure, reducing cooling capacity.. This is all 100% theory though, I could be wrong. Key take away, keep your coils clean, or your tubes clean, or your brazed plate clean. :)
@@FrenchBeefCDN the metering device would definitely starve Especially on hotter days. Although the quantity of refrigerator didn't change the state that it's in has. Dirty condenser, bad fan motor and very hot days will yield more gas than liquid in the condenser thus starving the metering device. You're basically feeding the txv hot discharge gas
@@dcmarvelunited5529 Until the HPCO opens, youre right. I guess it depends on many variables. Cooling Capacity would be greatly reduced.
8:30, that's surface tension you're looking for... otherwise, this was an interesting upload.
Problem is it's a York only way to fix it is to get another better unit
I'm wondering with the unit being down and not getting cleaned on a daily basis my guess is the unit was working to hard trying to do its job and with the unit being dirty case the fan to sized up
❤️
do ya like york predator units
I seriously wonder what dish soap would do compared to the viper. Dawn soap. Will be microchannel safe, but possibly better for grease, but might cause a foaming hell I guess.
Dishwasher detergent works well for removing grease, and contains anti foaming agents.
Are gas flex lines okay for outdoor use in your world ? I never do it in Oklahoma, but I know a few that do ...personally do not approve. im sure you would agree
still summer for you guys?!
I was like 107 in December? 😂
Okay
'DeeDee, no!' 🤣🤣🤣🤣
I don't understand why there don't get a extension for there exhaust fans that the AC don't sucks in the crap
audio?
Even after cleaning it, you banging on it, it was still dropping dirt. plus with it being smashed up. Just let the poor thing die at this point.
My thing is if they had space for all that duct work why didn't they just move the whole equipment closer to the area ? Makes no sense oh nvm it just looked long from the camrea position
No proper heat transfer Chris
I know the boards have logic, but the designers sure didn't. They pipe the TXVs along the filter access and then they spring leaks after filter flippers beat them up. I've also had may of them with the blower wiring running over a piece of angle steel that causes rubbing and an eventual short. Not the worst, but also not my favorite unit design by far.
I’m guessing, this unit needs to be replaced.
man those US motors suck, at least for pools. The .75 and .95 HP pool motors have like 0 tolerance for voltage drops of any kind and only last a couple of years
