DINING AC NOT COOLING ( APPRENTICE SERIES )

[@jasonyeager9102]

I like the idea of an apprentice type explanation. They would be perfect for new guys that may not understand the more advanced stuff just yet but you also get the point across which may lead to better understanding for us that are not new to the trade but newer to commercial refrigeration (for your walk in cooler/freezer videos).

[@Anihmal]

You have advanced my career in ways I cannot even explain, I appreciate your videos

[@HVACRVIDEOS]

I appreciate you watching

[@stephennichols4815]

I am retired now from doing air-conditioning and refrigeration for 40 years and now a friend of mine has his own company and I trained him 30 years ago and he calls me for the refrigeration and larger commercial systems his son is 20 years old and started working with his dad and he wants me to work with them and help train his son because of the way he learned working with me and I just like repairing and keeping up with the technology and still learning everyday I do like you and talk about what I'm thinking and why as I'm troubleshooting naming the possible causes of the symptoms we are finding eliminating the basic ones first that can be visually or observed by knowing sequence of operation and watching seeing or hearing something not happening or unusual giving us a place to start and find the problem most customers can describe the way systems normally operate and the issue they are experiencing and point you in the right direction of what to look at. I enjoy watching your videos and troubleshooting processes and I learned about the newer technology and seeing different ways other technicians troubleshoot find better ways to do repairs and diagnostic. I have always been open for suggestions and listen to what others have to say sometimes they have a good suggestion or gives you a little information to two good ways of doing something and you come up with a great way just by listening and thinking ,stay open minded and keep on keeping on doing your best and thinking about could I have done anything better

[@AllTattedUp13]

Ahh yes, good ol intermitten calls. Been doing hvac for almost 30yrs now and it seems im a magnet for the weird intermitten calls 😂. You never stop learning in this trade thats for sure.

[@mark351]

Intermittent problems are the worst. Takes a long time to see a pattern let alone the problem. This was a great lesson for an apprentice.

[@DJSubAir]

Yeah it takes time

[@FishFind3000]

Do more apprentice series. I loved watching your videos from the educational side.

[@alext424]

As a first year HVACR apprentice currently in trade school, I can say that this video is extremely helpful. Please keep making more of these apprentice guide type videos. Huge thumbs up to you Chris!!! 👍🏻👍🏻👍🏻

[@HVACRVIDEOS]

Thanks bud, I will do my best

[@SoullessProductions]

35:20. Turning into dr sues. "One compressor two compressor three compressor four..." " This condenser, that fan motor, that drain, and more!"

[@HVACRVIDEOS]

Lol

[@DeclanBirmingham]

That wasn't too long. I like the longer videos. I have gone back and watched all your videos posted over the last 5 years. The long ones are the best.

[@HVACRVIDEOS]

Thanks for watching Bud

[@R20sjshshwgdkfmsnwhfjs]

I don’t work in hvacr, but I love these videos because it educates me as a home owner on simple things like cleaning my condenser and ice machine. With that said I adopted the phrase “please don’t blow up” and said it as a joke from time to time. One day I had a problem with my well’s VFD pump controller. I turned the breaker off and the well company came out. Guy said “turn the breaker on let’s see what happens” I said “1,2,3 please don’t blow up” and it blew up. Shot sparks everywhere. Now this phrase lives rent free in my head. Thanks Chris

[@jasonjohnsonHVAC]

Discharge superheat is another metric to be utilized and should be more utilized by people. It takes into account the heat of compression as well. Most chillers use discharge superheat as a closely watched metric of performance. It will add to your inventory of knowledge. You can have normal suction superheat....but have high discharge superheat. If any of you work in heavy commercial, you know already.....for those that may want to get into the bigger stuff....learn it now, learn how to use it....you will be ahead of the game. Great video Chris......absolutely loved the style of this video.....it will help many many people. Kudos to you

Im someone who is currently going through a technical high school. Im in the HVAC program and these videos and all of your videos will definitely help me learn more. Ive been watching for more then 5 years i think. And these videos always teach me something new. I hope to start my apprenticeship in my 12th year thanks to my county. And this will only help me make sure i get there and do well. Thank you so much for these videos.

Chris you are a great teacher and explain things in a down to earth and relatable way that a new tech can learn from. I wish that I was starting over and could work for you. I went through UTI back in 1981 for A/C, Refrigeration, Heating and solar and of all the teachers that was one that truly knew how to make the complicated understandable. Thanks so much for taking us along for training day.

I will do my best to make that happen

[@combrains1]

Your comment about digital probes is spot on. The same thing gets said about diagnostic scan tools in the automotive industry. The difference between a bad tech and a great tech is the ability to use their brain and interpret what their tools are telling them, rather than just blindly shotgunning parts at a system because 'their app told them this was the problem'

[@HVACRVIDEOS]

Very true

[@Blakethegoat]

Thanks Chris, been watching this channel since I started hvac school in 2021… I got my 2 year degree and did heavy industrial install for about 1.5 years. now I’m 1 week into service. Thanks for the videos I’ve almost learned more from you than school✌️

i listened to this while cleaning out my window unit. was feeling great about myself until i had to disassemble the blower LOL. love the new format, i think it's gonna help a lot of people :^)

[@DBVintage]

I’ve learned a lot from watching your videos over the years. I have a GE monogram built-in refrigerator. Through watching a lot of your videos on walk-in coolers and such I’ve learned about the various controls and have done a few DIY repairs. One thing I learned from you was about fan delay after defrost, I know my monogram has it and I think my neighbor up the road has a subzero with the same feature in the freezer.

[@ThePowerofElectricity]

This was a great unit for learning on. Complex intermitten issues coming back to a simple fault such as a set of bad relays. And you did a great job at explaining how everything interacts with other functional groups

[@electriciants7927]

I like this series. Very informative. Great job explaining the steps and details.

I definitely agree on your opinion on apprentices. I see it all the time and current its catching up to me too, where I have do to stuff i never did before, dont know shit about but get yelled at for making a mistake that coast money. Which causes frustration on all sides involved. Had I had more extensive training as apprentice or even after i finished the apprenticeship we wouldn't run into these costly and frustrating problems.

I'm not an AC tech. But because of your videos I can hear a local restaurant's AC short cycling. I want to mention it to the manager who probably has no idea. But I can't save the world. I'll just finish my tea, leave a tip for the waitress, and move on to my next destination. The food is great. But the next time I go back it will probably be sweltering inside. Oh well.

Great video, Chris. Your videos have always been a 'must watch' but this takes it to a new level with the detail and gems of information. Well done,and thanks for taking the time and effort to put it all together.

It's the rolling shutter effect. That's why motors seem stopped or backward sometimes. It's really neat stuff that has to do with the way our modern cameras work.

[@the_1drummajor]

@35:10 I would have called you out on it too; but then I'd get fired; but then you'd probably realize your mistake later down the line, and then we both realize we're both at fault, and we learn something together. That's the beauty of life's hard lessons!

I am an electrician, and still enjoy watching your videos. At least my field is somewhat related to yours. I have no use for the HVACR specific info tho.

[@HVACRVIDEOS]

Lol, I'm glad your here

[@zidane2k1]

I'm not in this field, but I think another good safety thing worth mentioning that probably applies to many fields is to never take shortcuts or skip steps that would cause you to do something in an unsafe manner just to save time, because this how many accidents happen that otherwise wouldn't have happened.

[@HappilyHomicidalHooligan]

27:45 I'm an Electrician and you touching the Relay wires and triggering the Relay doesn't mean the Relay itself is bad, it could be the wires are loose on the terminals and not making a good connection... HOWEVER, most likely, the Relay is (or is going) bad and replacing both the #3 and #4 Fan Relays is a wise idea...just in case...

[@danpresson]

Awesome video Chris

[@HVACRVIDEOS]

[@TonyNaggs]

Fan direction on video: the video takes 30 still pictures per second, whether the fan looks as though it is going forwards or backwards is about synchronisation between the video & fan speeds. This strobing effect famously makes wagon wheel spokes look like they are running backwards in Western movies. 🎞️🤠

[@mynamesdan2164]

Ive had a few calls like this stump the hell out of me with my analog guages. Do all your techs get the fieldpiece bluetooth set!? Just because this whole video is explained as someone who has $1000s of dollars in probes and equipment! I recognize these things are advancing but gal dang! Great video as always either way!

[@ChristianRodriguez-ww9jz]

Perfect explanation.🙏🏽

[@seeda]

Shutter speed due to Wagon wheel effect, Film takes photos in a series When filming a rotating object, each frame captures a different position of the object. For example, if a cartwheel with 24 spokes rotates once per second, each frame of the film will show a spoke in the same position as the previous frame. This makes the object appear stationary.

[@christay21]

that stile of video is good to see the way you do things (your aproch to do repears)

[@vv-cv6ud]

I worked in a restaurant, always curious to learn the process behind of diagnoses . May be I will join the trade school

[@HVACRVIDEOS]

I hope you do, we need fresh minds

[@750kv8]

31:35 - Shutter effect. Rolling shutter effect if the blades / spokes etc. of a spinning object seem to bend into a funky shape seen on the camera. Camera FPS is most often either 30 or 60 (here we assume a very short shutter time and no dropped frames etc.), so lets say, a 60 FPS camera recording a 3-blade fan on a 6-pole **sync** motor on 60 Hz AC power, the blades will appear not spinning at all on the camera, BUT, most of these fans are driven by an induction motor, and there's a rotor slip. Thus on the camera, the fan impeller will look like spinning relatively slow *backward*, practically displaying the rotor slip itself. It's a more complicated case if the number of blades don't match the number of poles or (round multiples of) the half of it etc., OR if the camera FPS doesn't match the AC frequency or the half of it; example, a 5-bladed fan on a 4-pole motor.

the fan motors are all spinning a slightly different rpm, could be due to the blades, capacitor, motor build itself, wind, air flow, voltage. it doesn't take much to look different strobing against video frame rates, but one looking way off could be a very out of spec capacitor.
