TROUBLESHOOTING, DIAGNOSTICS AND RESOLUTION OF A HVAC OR AC UNIT ON A SERVICE CALL 

You my friend would make a good teacher at any school, it seems to me that you love what you do and that makes the difference. Worked on RTUs many years ago and now only doing residential, keep up the good work! We wll be watching you here in walnut, ca

That unit was made on the 4th week of 2001. Carrier units have unique serial numbers, first 2 number are the week of the year, last 2 numbers the year it was made in. Great video brother!

Had to come back to watch again, tons of good info . Thank you

👍👍 thank you for this. Watching this took some of the anxiety i feel from being a brand new tech.

Covid Lockdown has me binge watching Hvac content and I must say this was one of the best vids I've seen thus far🔥🔥💪🏾

Awesome video, thanks for making it!

go over everything ive been searching for a great Hvac RU-vid page this is great! Thank you

Man really appreciate the info one of the best videos I've seen bout to blow up the rest of feed.

Great video, I start my first commercial maintenance and service job this week!

Great training, i like the way you explain .

I enjoyed your video as well! You are funny. Thanks for posting! Subscribed with all notifications 👍

Excellent diagnostics

This was a great diagnostic video

Excellent video, very educational!!! Watched you for the very first time and subscribed to your channel. Loved watching it in Vanvouver, BC, Canada

This video is awesome, it's an actual no cool call. Seems other's videos were staged, planned, and set-up. That's fine there is education value in that. This video can be helpful to techs bc it's real world, and takes us through the adventure of trouble shooting

One of the best videos on RU-vid

Lots of good information on this video. Thanks.

biggg up! great diagnosis, great walk through!

Great video!

I found gold!!! This video is so helpful and will definately help my grandson in his new hvac job! Thank you so much!!!

Great work mon!

Very helpful. You have a short explanation for everything. Still trying to learn this field.

It’s a little different with a building as such with vavs but In general I do utilize google maps. Pin the location downstairs, then walk to the roof and return back to your pin location. This works well with warehouse exhaust fans as well.

Really enjoyed your real life walk through diagnosis👍 Subscribed! Look forward to more. Cheers from Alberta!!!

great video

Those unit have a known problem with the condensers , the coils are stacked one stage on top of second stage and the top coil always gets recirculated condenser air so one stage always runs higher head than the other. Usually fix that issue with a old style hail guard but you can't get those anymore so many fabricate their own to keep them running. more often than not you find these with all the high pressure switches disconnected. They make a 25 ton version with semi hermetics and those slab coils are thick and get plugged so thoroughly you can't clean them with out the fire hose treatment. basically you want to get rid of these as they are money pits, sometimes the belt break and grab all the capillaries and rip them out of the evaporator, I have seen them eat so many compressors the condensers get clogged with braze balls and shellac from burnt motor windings etc etc.

great info

thank you... great video

You a beast in these streets

Excellent.

Thanks for the video =)

Great RU-vid videos A+++

Just subd, this was a really good class sir

Wow is a lot common but know body hit like button, I guess I’m only first one great content always thanks you again

Good video

Great video D2D! Wanted to ask if there is a big need for HVAC techs/installers in NYC. I’m in school in NJ and looking for employment outlook around here.

I enjoyed the walk through on this service call. I’m in the market for a clamp meter would you recommend the Amorobe meter for a HVAC/R

Boa noite tira uma dúvida as placas dos equipamentos centrais normalmente sao modelos padrões. Ou tem diferença.? Sou Brasil acompanho seus videos. Parabéns

Nice job, great explanation and very thorough 👍🏼

Great service call fam ! send mi ur link so that i can learn.I am in school at the moment studying hvac 😊

Thanks

No building automation? That's how you find out rite away which one is down. I'd be suprised if a setup like that had no automation,if it doesn't than yeah that sucks but you're rite about checking for no condensate, good place to start for sure

How did you run the motor with other capacitor such as the wiring goes? Since you removed both brown wires??

Thanks for great video, just wonder that where the compressor capacitor locate?

What about the fan spinning opposite direction that’s diagnostic to.

how'd you get it to run in the proper rotation?

Hey my friend are you from Jamaica? My family is from Jamaica as well

Those CLO boards have to read a minimum of 2.5 amps within 1 second of startup. It doesn’t lock out with high amps.

Would have been nice to see its approach, once everything else was made good. Approach can give a good indication of proper charge when there's no liquid line port.

what model of unit was this ?

What happens if the condenser coils are cleaned but still you are expiriencing high pressure

Hi pls how to charge 407 package unit reheem

D2D Are you Hawaiian?

Need to be careful your touching live voltage wires and stuck your finger in the Contactor while it was pulled in

24:56 how ?

Are you a jamaican

I know who you are. Your ricky?

80-

Not how a lockout board works. Doesn’t look for high amps it looks for low amps.

What, slow down

It’s a Sucker

i have zero faith in myself knowing how to diagnose anything electrical

"...is that factory ?"😂😂😂 That should be put on a T-shirt for your company! 😂😂

Great video!!
