Checking the Charge of An R-410A Air Conditioner with Quick Reference Cards!

In this HVAC Training Video, I show How To Check The Charge of an R-410A System Using Quick Reference Cards to Show the Step by Step Procedure. The Indoor Air Handler is Equipped with a Piston Metering Device so We Use the Total Superheat Method to Check The Charge! I use Quick Connect Test Gauges and a Dual Temperature Meter to Calculate Both Total Superheat and Subcooling.
