Troubleshooting Indicators for a Liquid Line Restriction, Low Airflow, Low Charge! Check the Charge!

In this HVAC Training Video, I Show How to Diagnose a Liquid Line Restriction, Low Indoor Airflow, or Low Charge by Measuring the Refrigerant Charge on a Manifold Gauge Set. I Show the Indicators for Pressures, Sat Temps, Superheat, and Subcooling. You Don't Need to Add Refrigerant to Try to Raise the Vapor Pressure Sat Temp. Simply use These Indicators for Troubleshooting! Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.

Thank you for using digital gauges on this video. Even though I can read analog ones, seeing the actual numbers and changes while you’re explaining makes it soooo much easier to understand and read. I hope you can use the digital ones more on your training videos like this

[christopherprince]

I just have to say this guy is so great. He makes everything in the video so easy to understand. As a young tech this is an enormous asset because what I have found is most people (older techs) don't want to help you or teach you anything, but this guy helps to bridge the gap when I am in doubt. Thank you sir.

I've been a tech for 34 years and I think your videos are fantastic. I put together an HVAC tech book for my technicians on how to do all types of troubleshooting and the technicians love having them. I know how much time and effort I put into my book and can appreciate how much time you spend doing these videos. I came across your YouTube channel and sent all my technicians the link to check out your videos and they really love them too. I just want to say thank you for making the industry better.

Watching your old videos to now is a literal jarring, I don't know what it is but you sound much more comfortable on camera now compared to your videos from 5 years ago.
