As a former York/JCI employee. You imagine having to fix the damn things when these POS'es break. Imagine having one fail QA and having to tear it apart because every 2nd or 3rd unit I tested Failed QA. So much so I forced my supervisor to get Me trained with a forklift so I can take Failed QA units off the line myself to keep our assembly line moving. I was a very outspoken employee and I was forced to work on the shit product assembly line. My supervisor hated EVERYONE except Me, cause I actually tried to do a good job. My Assembly Line never made great leaps in improvement, but I worked hard enough to move on in My life.
This was the most basic call.bad cond.fan motor. I have worked on just about every unit out there and changed cond.fan motors on all of them.and the 15ton yorks have 3ph cond fan motors wich last for life of unit.the 12 ton unit in this video is not a bad unit.preditor.all yorks under 5tons yes they are trash.
Kind of unrelated but back in college I interned at the JCI campus in York, PA as a computer engineer working on stuff with the centrifugal chillers. Like the ones that are 100+ TR units
With that failure rate in production there's a problem with the design. If you have a bad design then people will put it together wrong and it's going to be a headache to fix the units regardless of if it's a correction on the assembly line or if it's in the field.
Bees don’t act like that, those bees have been poisoned. If they were on the far side of that wall, they would leave you alone; if they were swarming they would be even more unlikely to pay much attention you as they don’t have a hive to defend. A local beekeeper would be happy to remove bees, usually for free.
Many times when people think it's a bee hive, its wasps or hornets. I had a relative that was a hobby bee-keeper and he was "on call" with the city in the case of a swarm, he would go and retrieve it. Most of the calls he got, he would get there and tell them it's wasps or hornets, and to call pest control.
As a beekeeper, I am sad to see sprayed bees, but you were exactly correct in interpretating bee language! Lol Bees can only sting once and then they die, so they try to avoid it if possible, and you met the outer perimeter guard bees that were very politely asking you to leave. If you came closer, they probably would have been flying into you and bouncing off to up the ante a little bit, and then finally they would have given their lives to protect the colony, and you would have been screaming like a little girl lol The fact they were just doing warning flights makes me think it was a pretty calm colony, not Africanized. But, when they are inside a wall and repairing it would be expensive, cutting them out isn't always a viable option. On the other hand, there is a lot of flammable materials inside the wall now, so in some situations you have to take the hive out anyway for safety. It's not a big loss for the bee population, because it's easy to make colony splits, and they aren't native bees, just important domestic bees that swarmed from someone's hive, but it's still sad.
"Bees can only sting once " That's not entirely true. Some bees (not all) have barbs on their stngers that can get stuck in some (not all) targets. Andthey don't avoid stinging because they know they're going to die, they avoid it because if they sting something then whatever they stung is going to retaliate. Animals in general only attack if they feel they have no other option, they don't do it out of revenge or to annoy you. I n some insects there is the chemical reaction that when one of them is killed it will release a chemical that puts the others in a killing frenzy but again you have to first kill some of them to trigger that. But you knew all of this already.
I like when you get angry and rant about these old units lol cause you are being completely honest and right, I've learned loads of stuff watching your videos. Great content man as always enjoying your videos and streams as well
Sometimes the beekeepers won't relocate them because of the risk. I've had 2 separate instances where multiple keepers I called wouldn't move a hive it due to the risk of it being africanized/aggressive and attacking a person or pet nearby. Makes me sad, but I understand why. Their liability insurance doesn't cover it.
@B I was today old when I learned wasps eat insects like cockroaches and clean up around 14 million tonnes of dead insects in the UK, but I can't get over my dislike of them. On the other hand without them we'd all be knee deep in dead cockroaches so....:)
Your rant made me smile. Glad to see that I'm not the only one who is occasionally tearing out their proverbial hair. The wiring on old Lennox package units usually make me want to punch myself.
You have always delivered as long as I’ve been watching. I hope to become as skilled as you in the HVAC-R industry. You are thorough and professional. Being that I am currently going through trade school for this field I greatly appreciate your efforts. Especially since most of the training is distance learning.Thank you for all of your hard work.
I am honestly impressed, I really enjoy your videos, but this one was a pretty awesome decision to raise the fan blade to adjust the air flow across the evaporator due to an over sized temporary fan motor.
We all get frustrated, especially on call. Just keep on keeping it real. I love being an HVAC tech the down side is being on call. You must take the good with the bad. I enjoy your videos keep up the good work.
The new political correct term is "Primary". So "Master Bedroom" is now "Primary Bedroom" and Metallica's third studio album "Master of Puppets" is now "Primary of Puppets".
Climb on top of the unit to change the fan motor. The whole fan deck will flip over to clean the coil. Flip one at a time. Make sure the wiring is well secured. FYI.
I really love the fact that you are so thorough in checking these beasts out, using your experience and seeking out the proper specifications as best you can for what should be inside these HVAC units and what was been "monkeyed-in" along the units' life. Getting them up and running in the heat outdoors that you are working in and taking personal precautions to keep you and your employees from heat exhaustion and heat stroke is great for keeping quality up and employees from leaving. Thanks for speaking up about bad designs from the manufacturers from the get-go. Saw it an awful lot in the decades I worked in the auto industry. Good and proper tools with the knowledge to know how to use them will keep the frustrations and customer complaints to a minimum for you. Straightening out the wiring to correct size and logical wire paths makes it much easier for you or the next service person in the future to work on the units. Great camera work too! Smart enough to understand where your customer is coming from as far as cost containment while trying to run their business and you giving your best to get them up and running again. Explaining what needs to be done along the way and showing before the procedure is started and after the procedure's completion really helps us understand the mechanics of a service call. You most certainly earn your keep and if I was a few decades younger, I would enjoy working with you and having you as a mentor. Thank you so much for your videos and "wrap-ups" at the end. Keep up your fine, fine work!!!
Great tip with fan blade depth setting... but what you're calling the 'leading edge' is actually the trailing edge of the fan blade. Think of how the air hits the blades--starts at the bottom on the leading edge and blows out the top. One other thing: weren't both stages off on high pressure? Why was the 2nd stage tripped?
When I'm training junior engineers / designers, I try to get them the opportunity to assemble, disassemble, and even pull routine maintenance on the kinds of equipment that they will be designing. That's not always possible, but having them watch training videos for maintenance procedures can help, coupled with adult supervision until they show signs of "getting it." Unfortunately, more and more things are designed in one location, then built somewhere far, far away... Another problem is when equipment gets designed to meet a price point - inevitably, things get done that are chintzy, to say the least. Consumer products for home use are particularly obvious examples. I could have modified that connection to have slotted tabs in the sheet metal or possibly spot-welded studs with nuts screwed on from the accessible side - but, what I'm wondering about was the obvious reinforcing "plate" that was screwed over the outside of that joint - almost as if the inaccessible screws still weren't holding the panel in place properly. Oh, well - nobody's paying me to fix the design! ;) BTW - even if you aren't allergic, you do *not* want to experience multiple bee-stings, as you can get sick, andif I recall correctly, develop a sensitivity to bee venom.
I don't work in HVAC in any way, I have AC units but I don't service any of them but I've become completely addicted to your videos for some reason. Love the cleaning ones so satisfying!
“DUMBASS” that’s my favorite phrase when I get frustrated too😂 simple adjustment to the condenser fan by lifting it a little bit to try to achieve a better sub cooling. A lot of techs would say good enough I’ll be back in a couple days. That little bit extra goes a long ways. That’s why Your new videos are the only notifications I get on my phone, and watch ASAP. Nice work
You can vent your frustrations to us anytime. Anybody who watches your videos has been in your shoes and knows exactly what it’s like to have a rough weekend on call. I guarantee the “engineer” who designed that unit doesn’t have a clue what it’s like to work in the field. If he did, he wouldn’t burry screws behind a panel.
Depending on the job, you'll usually just relax and do minor things around the house and it's not an issue because you're exhausted. That was my experience with emergency flood industry.
What a great video, I learned a lot I did not know. I Can picture me having to do that sometime in future and be able get the job done. Be very carefull up there as wasps can be very dangerous. I removed a cover on an exhaust fan to check the belt and they all came out and chased me to the edge of the roof and stung the living shit out of me. luckily I was not allergic to them, but they did leave some welts on the arms and back.
Thank you for not mounting the cap to the support arm. I am so tired of finding that left by others as a permanent repair. And yes, I have cursed those three screws myself.
You don't need to apologize for being frustrated on a weekend call. We've all been there. At least you don't curse like a sailor and throw tools like a HVAC Tech I worked with some years ago. Haha! Keep up your very informative videos. I've been in the field for 22 years and I'm still learning new tricks and tips.
Of all the YT'ers that deal with HVAC, your vids are the best. I'm an industrial maint tech in aerospace (not too far from you), wish some of our techs would/could give the same attention to detail as you do.
hahaahah your raging about some screws was soo fun haha. You're like my boss - I work at a computer repair facility and my boss always rages about motherboard screws mounted under the cooling heatpipe on laptops (so you have to remove both cooling fans and the heatpipes and everything to get the motherboard off), and cables routed, or screws covered under the motherboard so you have to dismount the whole motherboard to dismount for example the display assembly. Or for example when the builtin SATA cable on some PCs are so short so you have to mount the drive and then use two screwdrivers to route the SATA cable into the connector because theres no room to get the finger down there and push the SATA connector in.
I've been watching your videos for a few months and i have learned a lot, but one thing stands out the most. I can say with certainty, that commercial gear that you work on and industrial gear that i get to work on is VASTLY different. Even contactors example, i have 3 phase (1a - 1200a) contactors that are 20 years old energize 24/7 every few seconds that have never been replaced, in all sorts of environments. How do these contactors go bad so often? I am 100% convinced that these things are engineered not to survive. Can't complain because it keeps guys like you in business.
Every York unit I worked on was junk, from small package units to large VAV units, and chillers. The smaller units would crack the pan where the compressor sits. It was a rooftop curb mounted unit, and the crack caused water to leak down into the building. Having a dead condenser fan on units with more than one fan, causes air from the operating fans to be drawn through the dead fans opening, bypassing the condenser. The air will take the easiest route. Good video
I've been watching your videos since the beginning of may and can't stop watching them, though I don't work in the hvac field I plan on doing so when I graduate highschool. I find your videos entertaining to watch.
WRT water in the condenser, it’s surface tension that keeps the water in. This product: CRC 14416 HydroForce Industrial Strength Degreaser, really lowers the surface tension of the water, and it doesn’t suck the oils out of your fingers. It might work (I haven’t tried) to use it in a sprayer mix on the coil to put a low surface tension water solution into the coil, then don’t rinse. The surface tension should be lowered enough that the water will not stay in.
Definitely, be real about these things in your videos! As annoying as the frustrating times can be, they also make success more worthwhile! From an audience perspective, anyone (like myself) who works in a trade will understand why and where you're coming from. I say keep doing what you're doing and I also liked the cut away to the screen capture of the diagnostic information!
Driving along reminded me of driving through Cape Town, it's similar to San Francisco in many ways. Except the seasons are reversed, they are only just beginning to get the first summer weather there. It was 90 deg there on Tuesday and they got all happy about it, but the rain was good this season, it filled up their reservoirs, a dry winter is bad news for them. Thanks for sharing the video. Best regards, Duncan South Africa
That's the weirdest screw placement ive seen in a while. The worst bolt I ever had to tackle cost me almost 3 hours of trying to turn the dam thing, then LOTS of heat but still wouldn't budge. Another hour later I figured out it had left hand threads. 🙄
I always use a piece of cardboard to cover the fan that isn't working. I use duct tape to hold it in place. It has worked for me every time I do it. It's temporary but it will get the unit going for the customer.
Never do that on a microchanel coil or you will have a busted coil. It work fine on a regular fin and tube coils. Reach to manufactory and they will tell you that.
So the higher head pressure from the lack of dual fans will take out a micro channel coil. Why are they making everything so freakin crappy these days??
@@Herman_aguilaMXGDL Been doing it for 6 years. Never have had a problem with blowing a coil. Head pressure never climbs over 30 degrees above ambient. If it ever does the pressure switch will lock out the compressor. There is a much greater chance of your fan blades ripping apart and tearing up the coil.
45asunder1 I’m glad you mentioned that, yes you have that chance the safety protect the system but, just imagine that the safety did not respond. We have a bust coil, some times is just at the joints easy to fix some other we are no so lucky. This never happens to me but I’ve attend to a Trane clase and that is what they were teaching. Also later on I get to know people that actually got experienced it first hand. Protect yourself and the customer and just do not do it. By the way congrats on your 6 years. I have 14 on AC and 8 on refrigeration and still learning.
5:04 HA! I feel your pain man, had to change a condenser fan motor and coil on one of these types of Yorks, not to long ago, WHAT A PAIN! Also thats a neat way to check capacitors never seen that trick before gonna have to try it some time.
I say one thing man we do a lot of the same things and that York unit I asked the same question what is the point of those screws it’s just dumb. Lol I’m on the east coast and it’s very humid here but hadn’t ever been in 120 degree weather. Keep making the videos man your definitely helping a lot of techs brother. I actually been thinking of moving to the west coast if I do and your hiring would love to have a sit down.
Always love your videos explains exactly what going with unit . Love your diagnostic skills. I have to admit I learned some thing new from every video. In this I learned a lot about airflow and pitch. Thanks.
York Unit straight up said “ hold on a minute playa”. I work on call every weekend until further notice. Gives me days off during the week for my daughters online schooling.
If you see bees like that again, grab your blower and GENTLY move them out of the way. If you crush too many they get the defense pheromones going and you’re in trouble.
I have bought a bit of time blocking off the fan that isn't working. As long as there is no division panel between it and the adjacent fan you will get a reasonable amount of airflow through the coil from the one fan. Depending on the unit blocking the one side off might get you to about 80-85* ambient. Head pressure might be relatively high but gets cooling until parts can be obtained.
Not all the engineer do things in that way. It is not uncanny to see engineer involved in productions lines and even working at some of the stages, testing their procedures and products. Whne you are told to maximize a thing in a certain way, lets say efficincy, you came with solutions like VFDs. You got a new weak link on the chain. Another guy says VFDs are garbage. But they never VFDs barely blow on elevators or train traction systems. There always corners and trade offs, you can get an unstopable VFD ?. YES. Cost ?. EXPENSIVE. Just put an indoor use VFD without any surge protection. Call it a day. It all about making desicions As Chris said, YORK know about this screws. They are there for a reason. Probably something went wrong, and those were needed, and trying to avoid them would force a bigger re-design. GM fail, Planes fail (Boeing actyually failed), NAsa fails, Samsung Fails ..... YORK fails. But you need to think how the unit did in the average. For example, having a board that put codes for you is NICE ENGinEERING ? Right ?.
It was after dark, I was on a small building top, I stuck my hand into a wasp nest looking for the disconnect. I got stung about 12 or 15 times before I could get off of the roof. I am allergic to bee stings. I swole up from my finger tips to the left side of my head. The doctor told me that if the swelling didn't start going down soon he would have to split my skin to keep it from bursting.
I do appreciate seeing you get emotional sometimes Chris but please don't make it every video. The best techs I've seen keep their cool at the worst times. It's definitely a balance but I'm sure you'll find it. Great video.
The drain "weep" plugs at 8:20 bit my ass decades ago when I first got in the trade. We got a bit of rain in Washington State, the motor lasted a week before it filled with water. Lesson learned
You really do the best job at explaining every single issue you run into, I've been in HVACR here in Phoenix for a year now, and sometimes I watch your videos just to see if maybe I missed something. Your videos literally help me do better at my job lol. But also, definitely call a local beekeeper and get those bees removed if you go to that location often.
When I first saw the new condenser fan motor at 16:00, at first I thought it had a green ribbon and string tied around it and was wondering why so fancy, until the view was closer and it turned out to be the ground wire with green masking tape holding it in place.
What a coincidence, I was working on one these Yorks today here in Florida. It was an EMS issue but still surprising to come home and see you working on the same type of unit lol
Could you use a sawzall with a thin blade and just cut through those three screws? When you we talking about the blade depth, I noticed a shadow on the shroud. Could you line up on that shadow line?
As a former automotive tech, I feel that frustration. Some manufacturers make an honest effort to consider the serviceability and repairability of their products, some don’t. When you are already in a bad mood and you get stuck working on an engineering failure, it’s hard not to get really mad. They probably had an issue with that panel rattling against the other panel under certain circumstances, so rather than fixing it properly, they added extra fasteners.
York equipment is cheap but you get what you pay for. I serviced that same RTU model years ago and had to replace the control board & low temp switches. The quality overall is not the greatest, everything shakes when the condenser fans are running. Also 2 of these units had faulty economizer actuators. The OEM actuator was CAD$600 each. I was shopping around and found a similar part at a lower price. In the meantime, I opened the actuators and found a couple of blown resistors that cost only a few bucks to replace. In the end I saved my Church CAD$ 1,200 for those actuators 😃
Well, if is hard to keep always friendly and polite when you have this emergency calls ... on sundays ... but this is what pay the bills. You should rotate with other techs to cover the weekend calls, so you can make plans for a given weekend you know you will be off.
I really like your self-criticism and your dialogues, in my opinion you should create a second channel where people could get to know you better not only from the point of view of your work and passion but also from the point of view of your person and if they want also of your family
Strange how the water hangs in the condenser fins like that. You'd think the designer would have thought that through and built something else. It would seem that these units wouldn't do well in wet, windy climates where water can cling to the condenser...and the screw placement inside the shroud!! Every mechanic has similar stories of nightmare bolts to get at, I'm sure. Another interesting one!
You initially made the compression ratio better by putting in that aftermarket motor head pressure was lowered. Less amp draw on the compressor, cooler compressor. System had less back pressure.. Why go back?
5:11 those units had a lot of problems with the condenser fan motors. Spent about 2 hours talking to a rep. About 2 years ago and he mentioned about the motors and the silly lazy work for the screws your mentioning. It be ok with the regular coils but the micro channel wtf too much time consuming then gotta slap the coils softly to remove the excess water. I use the battery vacuum pack out with the compact toolbox my water hoses coils cleaners all inside & dolly on bottom and wheel my a** around instead of walking lol best part my supco umbrella hooked up for some shade 👌
As long as the have never been sprayed, the beekeeper, also known as apiarist, may them for (or for a small fee, such as travel reimbursement). Beekeepers charge based on the method required. Have the owner call the town and see if they have

Hi, at 13:51 you mention that the subcooling temperature is too high probably because the condenser fan is moving too much air. I recall from working with power electronics that increasing the airflow would reduce the thermal resistance and increase the rate of heat transfer. Yet the opposite seems to be happening here. As Derek of VGG would say, HELP ME UNDERSTAND! :)
Part of the consideration for heat transfer is not only the amount of fluid (in this case, air) but also the rate of flow. If the rate of flow is too high, depending on the thermal conductivity of the fluid and the heat exchanger, you can have an issue where the fluid is not in contact with the heat exchanger long enough to draw the heat away. Almost every cooling system will either have a maximum pump speed or a restriction to limit the maximum speed. It’s the same idea as a car engine overheating because someone removed the thermostat. It seems almost counter-intuitive, but if the cooling fluid/air cannot be in contact with the item that needs to be cooled for long enough to actually absorb a reasonable amount of heat, the item can still overheat.
that bit about putting on 1075hp on an 825hp, and it not allowing air to absorb as much heat from condenser because of higher rpm, that was very educational for me. I had no idea. I always put on a bit stronger motors to compensate for diff in rpm and not overamp. I thought it would only do better at higher rpm since it is pulling more air through. But so far I've only worked on residential units. So what the hell do I know
As a lifetime mechanic and shop owner, you cant imagine the insane stuff we ran into. Like having to do 4 hours of work just because a bolt was covered by another piece of equipment. On and on. My mantra has always been that no engineer or designer cannot do anything until the have repaired cars for 5 years. Then they can start to design things. To heck with the bean counters.
Lol my friends always laughed at me for taking my makita blower to the roof on PM’s. I would blow out cabinets and spider webs. Works on drains too! One of my good friends who is a large equipment person for York which is US air as you know. I always teased her about the crappy cabinets and rub outs spots!
I'm pest control in NorCal. Those bees are a structural pest in the walls. It's sad but occasionally a colony have to be delt with properly. A shop-vac with soapy water is the preferred method, but some of the "larger companies" out there will just spray it and walk away.
No one realizes how hard it is being the on-call guy. You have all of your customers, plus call ins.....All on your shoulders... It is a tough job! Especially when it is hotter than Satan's $all sack!
Totally agree with that york unit Chris it is a pain for screws to be in a places that makes no sense just feels like bull man Feels like kicking the crap out of it 😆 but it is what it is man York being york and those bees its crazy seeing so many I would of not even got that close Got stung one time on the side of my head one hornet I tell you Felt like someone had thrown a brick excruciating pain Bees stay away unless I have spray
Never forget brake clean (not the non chlorinated crap) kills quick and if things get real bad lighter in front of the spray I would rather them live but I’m allergic so if they want to party let’s go.

For the 1st time we as technicians have such a voice. The manufacturers need to see what they are doing. Good job. The more real the better!
“ it’s Sunday.... I’m trying you know?.... like .....fuuuhh...... what a dumbass....” totally relatable brother.
I really love the fact that you are so thorough in checking these beasts out, using your experience and seeking out the proper specifications as best you can for what should be inside these HVAC units and what was been "monkeyed-in" along the units' life. Getting them up and running in the heat outdoors that you are working in and taking personal precautions to keep you and your employees from heat exhaustion and heat stroke is great for keeping quality up and employees from leaving. Thanks for speaking up about bad designs from the manufacturers from the get-go. Saw it an awful lot in the decades I worked in the auto industry. Good and proper tools with the knowledge to know how to use them will keep the frustrations and customer complaints to a minimum for you. Straightening out the wiring to correct size and logical wire paths makes it much easier for you or the next service person in the future to work on the units. Great camera work too! Smart enough to understand where your customer is coming from as far as cost containment while trying to run their business and you giving your best to get them up and running again. Explaining what needs to be done along the way and showing before the procedure is started and after the procedure's completion really helps us understand the mechanics of a service call. You most certainly earn your keep and if I was a few decades younger, I would enjoy working with you and having you as a mentor. Thank you so much for your videos and "wrap-ups" at the end. Keep up your fine, fine work!!!
Great tip with fan blade depth setting... but what you're calling the 'leading edge' is actually the trailing edge of the fan blade. Think of how the air hits the blades--starts at the bottom on the leading edge and blows out the top.
One other thing: weren't both stages off on high pressure? Why was the 2nd stage tripped?
Good question, but he did say they were both off on high head pressure. Cause for that, I have no idea.
Just from watching youre videos and doing what you say ( big picture diagnosis ) you have saved me lots of money and im doing the work my self .
When I'm training junior engineers / designers, I try to get them the opportunity to assemble, disassemble, and even pull routine maintenance on the kinds of equipment that they will be designing.
That's not always possible, but having them watch training videos for maintenance procedures can help, coupled with adult supervision until they show signs of "getting it."
Unfortunately, more and more things are designed in one location, then built somewhere far, far away...
Another problem is when equipment gets designed to meet a price point - inevitably, things get done that are chintzy, to say the least. Consumer products for home use are particularly obvious examples.
I could have modified that connection to have slotted tabs in the sheet metal or possibly spot-welded studs with nuts screwed on from the accessible side - but, what I'm wondering about was the obvious reinforcing "plate" that was screwed over the outside of that joint - almost as if the inaccessible screws still weren't holding the panel in place properly.
Oh, well - nobody's paying me to fix the design! ;)
BTW - even if you aren't allergic, you do *not* want to experience multiple bee-stings, as you can get sick, andif I recall correctly, develop a sensitivity to bee venom.
I don't work in HVAC in any way, I have AC units but I don't service any of them but I've become completely addicted to your videos for some reason. Love the cleaning ones so satisfying!
“DUMBASS” that’s my favorite phrase when I get frustrated too😂 simple adjustment to the condenser fan by lifting it a little bit to try to achieve a better sub cooling. A lot of techs would say good enough I’ll be back in a couple days. That little bit extra goes a long ways. That’s why Your new videos are the only notifications I get on my phone, and watch ASAP. Nice work
Surface tension, not vapor locked! ;)
Yeah im not very good with proper names.....🤣
You can vent your frustrations to us anytime. Anybody who watches your videos has been in your shoes and knows exactly what it’s like to have a rough weekend on call. I guarantee the “engineer” who designed that unit doesn’t have a clue what it’s like to work in the field. If he did, he wouldn’t burry screws behind a panel.
“I dont like to make plans or do anything cuz then ill get my hopes up” - the saddest thing ive heard
Well when you own your own business you never truly get a day off!
It's called being on-call/standby...it does suck
Depending on the job, you'll usually just relax and do minor things around the house and it's not an issue because you're exhausted. That was my experience with emergency flood industry.
Totally understand your frustration good to see you keep it real. That's just what it's like in big bad world.
What a great video, I learned a lot I did not know. I Can picture me having to do that sometime in future and be able get the job done. Be very carefull up there as wasps can be very dangerous. I removed a cover on an exhaust fan to check the belt and they all came out and chased me to the edge of the roof and stung the living shit out of me. luckily I was not allergic to them, but they did leave some welts on the arms and back.
Been watching your videos for about a year now. Great learning experience and I can almost tell the problem before you say it.
It was so good to see you rant on York like that. The setup makes replacing the coil a pain in the ass too.
Thank you for not mounting the cap to the support arm. I am so tired of finding that left by others as a permanent repair. And yes, I have cursed those three screws myself.
I do enjoy your rants, I couldn’t agree with you more
Man I feel ya I been doing service work for twenty years I been there man I completely feel for ya bro
You don't need to apologize for being frustrated on a weekend call. We've all been there. At least you don't curse like a sailor and throw tools like a HVAC Tech I worked with some years ago. Haha! Keep up your very informative videos. I've been in the field for 22 years and I'm still learning new tricks and tips.
Of all the YT'ers that deal with HVAC, your vids are the best.
I'm an industrial maint tech in aerospace (not too far from you), wish some of our techs would/could give the same attention to detail as you do.
Thanks bud
hahaahah your raging about some screws was soo fun haha.
You're like my boss - I work at a computer repair facility and my boss always rages about motherboard screws mounted under the cooling heatpipe on laptops (so you have to remove both cooling fans and the heatpipes and everything to get the motherboard off), and cables routed, or screws covered under the motherboard so you have to dismount the whole motherboard to dismount for example the display assembly. Or for example when the builtin SATA cable on some PCs are so short so you have to mount the drive and then use two screwdrivers to route the SATA cable into the connector because theres no room to get the finger down there and push the SATA connector in.
I've been watching your videos for a few months and i have learned a lot, but one thing stands out the most. I can say with certainty, that commercial gear that you work on and industrial gear that i get to work on is VASTLY different. Even contactors example, i have 3 phase (1a - 1200a) contactors that are 20 years old energize 24/7 every few seconds that have never been replaced, in all sorts of environments. How do these contactors go bad so often? I am 100% convinced that these things are engineered not to survive. Can't complain because it keeps guys like you in business.
Every York unit I worked on was junk, from small package units to large VAV units, and chillers. The smaller units would crack the pan where the compressor sits. It was a rooftop curb mounted unit, and the crack caused water to leak down into the building. Having a dead condenser fan on units with more than one fan, causes air from the operating fans to be drawn through the dead fans opening, bypassing the condenser. The air will take the easiest route. Good video
I enjoy watching your thoroughness , you know your stuff , very common sense
'Excuse the coke nose', brilliant :D
I've been watching your videos since the beginning of may and can't stop watching them, though I don't work in the hvac field I plan on doing so when I graduate highschool. I find your videos entertaining to watch.
WRT water in the condenser, it’s surface tension that keeps the water in. This product: CRC 14416 HydroForce Industrial Strength Degreaser, really lowers the surface tension of the water, and it doesn’t suck the oils out of your fingers. It might work (I haven’t tried) to use it in a sprayer mix on the coil to put a low surface tension water solution into the coil, then don’t rinse. The surface tension should be lowered enough that the water will not stay in.
I like that tip about locating the capacitor.

Definitely, be real about these things in your videos! As annoying as the frustrating times can be, they also make success more worthwhile! From an audience perspective, anyone (like myself) who works in a trade will understand why and where you're coming from. I say keep doing what you're doing and I also liked the cut away to the screen capture of the diagnostic information!
Driving along reminded me of driving through Cape Town, it's similar to San Francisco in many ways.
Except the seasons are reversed, they are only just beginning to get the first summer weather there.
It was 90 deg there on Tuesday and they got all happy about it, but the rain was good this season, it filled up their reservoirs, a dry winter is bad news for them.
Thanks for sharing the video.

That's the weirdest screw placement ive seen in a while.
The worst bolt I ever had to tackle cost me almost 3 hours of trying to turn the dam thing, then LOTS of heat but still wouldn't budge. Another hour later I figured out it had left hand threads. 🙄
I always use a piece of cardboard to cover the fan that isn't working. I use duct tape to hold it in place. It has worked for me every time I do it. It's temporary but it will get the unit going for the customer.
I do that too. Often it'll get you through to when you can get a replacement fan.
Never do that on a microchanel coil or you will have a busted coil. It work fine on a regular fin and tube coils. Reach to manufactory and they will tell you that.
So the higher head pressure from the lack of dual fans will take out a micro channel coil. Why are they making everything so freakin crappy these days??
@@Herman_aguilaMXGDL Been doing it for 6 years. Never have had a problem with blowing a coil. Head pressure never climbs over 30 degrees above ambient. If it ever does the pressure switch will lock out the compressor. There is a much greater chance of your fan blades ripping apart and tearing up the coil.
45asunder1 I’m glad you mentioned that, yes you have that chance the safety protect the system but, just imagine that the safety did not respond. We have a bust coil, some times is just at the joints easy to fix some other we are no so lucky. This never happens to me but I’ve attend to a Trane clase and that is what they were teaching. Also later on I get to know people that actually got experienced it first hand. Protect yourself and the customer and just do not do it.
By the way congrats on your 6 years. I have 14 on AC and 8 on refrigeration and still learning.
5:04 HA! I feel your pain man, had to change a condenser fan motor and coil on one of these types of Yorks, not to long ago, WHAT A PAIN! Also thats a neat way to check capacitors never seen that trick before gonna have to try it some time.
I say one thing man we do a lot of the same things and that York unit I asked the same question what is the point of those screws it’s just dumb. Lol I’m on the east coast and it’s very humid here but hadn’t ever been in 120 degree weather. Keep making the videos man your definitely helping a lot of techs brother. I actually been thinking of moving to the west coast if I do and your hiring would love to have a sit down.
Always love your videos explains exactly what going with unit . Love your diagnostic skills. I have to admit I learned some thing new from every video. In this I learned a lot about airflow and pitch.
Thanks.
York Unit straight up said “ hold on a minute playa”. I work on call every weekend until further notice. Gives me days off during the week for my daughters online schooling.
If you see bees like that again, grab your blower and GENTLY move them out of the way. If you crush too many they get the defense pheromones going and you’re in trouble.
I have bought a bit of time blocking off the fan that isn't working. As long as there is no division panel between it and the adjacent fan you will get a reasonable amount of airflow through the coil from the one fan. Depending on the unit blocking the one side off might get you to about 80-85* ambient. Head pressure might be relatively high but gets cooling until parts can be obtained.
absolutely awesome being able to ride out on the job via YT and learn from you..THANK YOU
Engineers vs real world people
Corporate vs stores
Not all the engineer do things in that way. It is not uncanny to see engineer involved in productions lines and even working at some of the stages, testing their procedures and products. Whne you are told to maximize a thing in a certain way, lets say efficincy, you came with solutions like VFDs. You got a new weak link on the chain. Another guy says VFDs are garbage. But they never VFDs barely blow on elevators or train traction systems. There always corners and trade offs, you can get an unstopable VFD ?. YES. Cost ?. EXPENSIVE. Just put an indoor use VFD without any surge protection. Call it a day. It all about making desicions As Chris said, YORK know about this screws. They are there for a reason. Probably something went wrong, and those were needed, and trying to avoid them would force a bigger re-design. GM fail, Planes fail (Boeing actyually failed), NAsa fails, Samsung Fails ..... YORK fails. But you need to think how the unit did in the average. For example, having a board that put codes for you is NICE ENGinEERING ? Right ?.
As an engineer - can confirm.
Did a great job , hvac tech's are the unsung heroes thanks for sharing the video.
It was after dark, I was on a small building top, I stuck my hand into a wasp nest looking for the disconnect. I got stung about 12 or 15 times before I could get off of the roof. I am allergic to bee stings. I swole up from my finger tips to the left side of my head. The doctor told me that if the swelling didn't start going down soon he would have to split my skin to keep it from bursting.
I do appreciate seeing you get emotional sometimes Chris but please don't make it every video. The best techs I've seen keep their cool at the worst times. It's definitely a balance but I'm sure you'll find it. Great video.
I know the simplest things we miss at times I know you always on point that is why I said that keep up the great work
And just like that, you confirm to me as a design engineer to never specify a York unit. Good thing they aren't that popular around here anyway.
Love the driving video....very Steve Lav....Thanks for sharing!
The drain "weep" plugs at 8:20 bit my ass decades ago when I first got in the trade. We got a bit of rain in Washington State, the motor lasted a week before it filled with water. Lesson learned
You really do the best job at explaining every single issue you run into, I've been in HVACR here in Phoenix for a year now, and sometimes I watch your videos just to see if maybe I missed something. Your videos literally help me do better at my job lol. But also, definitely call a local beekeeper and get those bees removed if you go to that location often.
When I first saw the new condenser fan motor at 16:00, at first I thought it had a green ribbon and string tied around it and was wondering why so fancy, until the view was closer and it turned out to be the ground wire with green masking tape holding it in place.
What a coincidence, I was working on one these Yorks today here in Florida. It was an EMS issue but still surprising to come home and see you working on the same type of unit lol
Could you use a sawzall with a thin blade and just cut through those three screws? When you we talking about the blade depth, I noticed a shadow on the shroud. Could you line up on that shadow line?
As a former automotive tech, I feel that frustration. Some manufacturers make an honest effort to consider the serviceability and repairability of their products, some don’t. When you are already in a bad mood and you get stuck working on an engineering failure, it’s hard not to get really mad. They probably had an issue with that panel rattling against the other panel under certain circumstances, so rather than fixing it properly, they added extra fasteners.
York equipment is cheap but you get what you pay for. I serviced that same RTU model years ago and had to replace the control board & low temp switches. The quality overall is not the greatest, everything shakes when the condenser fans are running. Also 2 of these units had faulty economizer actuators. The OEM actuator was CAD$600 each. I was shopping around and found a similar part at a lower price. In the meantime, I opened the actuators and found a couple of blown resistors that cost only a few bucks to replace. In the end I saved my Church CAD$ 1,200 for those actuators 😃
Thanks Chris, hopefully York sees your video, engineers need to wear our shoes!
Thats a great tip for adjusting the fan blade depth for a temp. Motor. Great content as usual
"excuse the coke nose" :)))
I always "scream like a banshee" at that one.
When I'm off of work I enjoyed seeing the other people work. :)
Well, if is hard to keep always friendly and polite when you have this emergency calls ... on sundays ... but this is what pay the bills. You should rotate with other techs to cover the weekend calls, so you can make plans for a given weekend you know you will be off.
I really like your self-criticism and your dialogues, in my opinion you should create a second channel where people could get to know you better not only from the point of view of your work and passion but also from the point of view of your person and if they want also of your family
Change a heat exchanger on a York. Screws are backwards. Needless to say they went back normal . I agree on York’s what were they thinking.
Man I can never miss one of your videos
Strange how the water hangs in the condenser fins like that. You'd think the designer would have thought that through and built something else. It would seem that these units wouldn't do well in wet, windy climates where water can cling to the condenser...and the screw placement inside the shroud!! Every mechanic has similar stories of nightmare bolts to get at, I'm sure. Another interesting one!
You initially made the compression ratio better by putting in that aftermarket motor head pressure was lowered. Less amp draw on the compressor, cooler compressor. System had less back pressure.. Why go back?
Am I the only guy who gets sad when he sees a turd like that and remembers putting them in new?
5:11 those units had a lot of problems with the condenser fan motors. Spent about 2 hours talking to a rep. About 2 years ago and he mentioned about the motors and the silly lazy work for the screws your mentioning. It be ok with the regular coils but the micro channel wtf too much time consuming then gotta slap the coils softly to remove the excess water. I use the battery vacuum pack out with the compact toolbox my water hoses coils cleaners all inside & dolly on bottom and wheel my a** around instead of walking lol best part my supco umbrella hooked up for some shade 👌
As long as the have never been sprayed, the beekeeper, also known as apiarist, may them for (or for a small fee, such as travel reimbursement). Beekeepers charge based on the method required. Have the owner call the town and see if they have
You are freaking awesome thank you for all your hard work and information.

Hi, at 13:51 you mention that the subcooling temperature is too high probably because the condenser fan is moving too much air. I recall from working with power electronics that increasing the airflow would reduce the thermal resistance and increase the rate of heat transfer. Yet the opposite seems to be happening here. As Derek of VGG would say, HELP ME UNDERSTAND! :)
Part of the consideration for heat transfer is not only the amount of fluid (in this case, air) but also the rate of flow. If the rate of flow is too high, depending on the thermal conductivity of the fluid and the heat exchanger, you can have an issue where the fluid is not in contact with the heat exchanger long enough to draw the heat away. Almost every cooling system will either have a maximum pump speed or a restriction to limit the maximum speed. It’s the same idea as a car engine overheating because someone removed the thermostat. It seems almost counter-intuitive, but if the cooling fluid/air cannot be in contact with the item that needs to be cooled for long enough to actually absorb a reasonable amount of heat, the item can still overheat.
Couldn’t you partially block the coil. Gr8 trick locating capacitor
that bit about putting on 1075hp on an 825hp, and it not allowing air to absorb as much heat from condenser because of higher rpm, that was very educational for me. I had no idea. I always put on a bit stronger motors to compensate for diff in rpm and not overamp. I thought it would only do better at higher rpm since it is pulling more air through. But so far I've only worked on residential units. So what the hell do I know
I don't blame you for being frustrated. just curious why you didn't pull the fan shroud to access those screws. looks easier to reach from up there
You think that weather's a trip we went from 94 degrees Monday to 32 and snow Tuesday in colorado. Never know what to expect here.
As a lifetime mechanic and shop owner, you cant imagine the insane stuff we ran into. Like having to do 4 hours of work just because a bolt was covered by another piece of equipment. On and on. My mantra has always been that no engineer or designer cannot do anything until the have repaired cars for 5 years. Then they can start to design things. To heck with the bean counters.
Muy buen video.. Aprendí algo nuevo. Con la altura de las aspas delos ventiladores. 👍
Great stuff as always!
Lol my friends always laughed at me for taking my makita blower to the roof on PM’s. I would blow out cabinets and spider webs. Works on drains too! One of my good friends who is a large equipment person for York which is US air as you know. I always teased her about the crappy cabinets and rub outs spots!
I'm pest control in NorCal. Those bees are a structural pest in the walls. It's sad but occasionally a colony have to be delt with properly. A shop-vac with soapy water is the preferred method, but some of the "larger companies" out there will just spray it and walk away.
love these in the car shots, don't know why but ... keep 'em comin' =)
No one realizes how hard it is being the on-call guy. You have all of your customers, plus call ins.....All on your shoulders... It is a tough job! Especially when it is hotter than Satan's $all sack!
Heck yeah i watched till the end. We know how you feel brother.....
Totally agree with that york unit Chris it is a pain for screws to be in a places that makes no sense just feels like bull man Feels like kicking the crap out of it 😆 but it is what it is man York being york and those bees its crazy seeing so many I would of not even got that close Got stung one time on the side of my head one hornet I tell you Felt like someone had thrown a brick excruciating pain Bees stay away unless I have spray
If you repair residential refrigerators you will know there are so many stupid designs on what the parts are put together
if you ever get in a sticky situation with bees dish soap or pb blaster is gonna be your friend
Never forget brake clean (not the non chlorinated crap) kills quick and if things get real bad lighter in front of the spray I would rather them live but I’m allergic so if they want to party let’s go.
Nice troubleshooting and checking the details to have a close to perfect ac, should have torch the bees lol
