Supercharge Your AHU Troubleshooting Skills with This Exercise

In this livestream, I will walk you through troubleshooting an chilled water AHU service call. The customer complaint was for a symptom of the actual problem, so I will show you how to take the needed readings to get the right solution.
You'll learn how to:
Identify the customer's complaint and assess the situation
Perform the necessary tests and measurements
Diagnose the problem and determine the best course of action
Make the necessary repairs or adjustments
This livestream is perfect for HVAC technicians of all levels of experience. Whether you're new to the trade or you're looking for a refresher, you'll learn valuable troubleshooting skills that you can use in your everyday work.

Like how you go from the basics of "common AC". This uses a different medium

Hello. Thanks for taking the time to talk about it. I hope I run into same scenario sooner. Have a god lunch.

[@isaacsanchez3966]

Keep doing what your doing these videos are educational

[@eimantaslapienis4662]

Great exercise! Thank you. Hopefully you can make more like this.

Air bound coil

[@GalacticAdventures69]

These are fun honestly

Pausing at about half way to say great video thanks so much. As soon as entering and leav8ng water revealed im thinking we wanna see a 10 degree split not 20. Been thinking refrigerant issues this whole time but its a little hard to picture what having a too high or too low superheat/ subcooling's effect would be on delta t. Other than that possible water flow issue is the only other thing i can think of after having come this far and eliminated other possibilities

[@bureaucratbayonet]

After finishing this...what a great learning opportunity! I was also thinking restriction after the coil but have not had enough experience to run into a situation of insufficient make up water. Thanks again!

[@anom2789]

thank you!

[@joeycrack4294]

As far as the low static pressure,. I would check the office area for doors and windows open.

[@strutt01]

BA dude. Thanks for your work.

Keep up the content like this

Another good one 👍

[@colejc]

thanks brotha
appreciate the video

[@HEFTYLEFTY303]

If your not getting adequate cooling to the space the vavs will end up driving wide open causing the low static problem

[@dennisbarkley1551]

Thanks😊

Am I missing something? Why is vertical water column relevant in a closed loop system? Is the pump not a recirculating pump?
Also, with the inlet gauge reading 1psi I would be weary of the reading unless it’s a compound gauge. The gauge might read 0 but the suction is in a vacuum.

[@HVACTIME]

It is a recirculating pump but the column is still relevant whether its a closed loop or not. There has to be enough water volume to properly function.

[@Swiminfool139]

Amps on the motor fla / rla?

[@joeycrack4294]

Shouldn't the inlet to the chill water coil be on the bottom of the coil in order to keep the coil flooded, which will help to give you a lower or proper outlet temp,

[@HVACTIME]

Ya i caught that after I started the training. I make mention of it through the class.

[@jameshendry9906]

All the VAV ARE OPEN CAUSING LOW STATIC

[@Swiminfool139]

Not enough gpm

Ductwork oversized

[@Swiminfool139]

Lined duct insulation fell off, blocking duct before sensor
