In this HVAC Service Call Video, I go over the Diagnosis of a Bad TXV using Subcooling and Superheat to figure it out. You know there is a problem when the evaporator is freezing and the vapor pressure is too low but you need to be able to figure out what that problem is. It may not be low on refrigerant! I will discuss how to determine the problem!

Supervision is needed by a licensed HVAC Tech while doing this as Experience and Apprenticeship garners Wisdom and Safety.
