This video is on Step by Step Directions for Checking the Refrigerant Charge on an HVAC Comfort Cooling unit that uses a TXV as a metering device. I go over how to tell if the charge is too low and if the charge is too much. These are general directions in a simple format that are easy to follow. This guide can be used in conjunction with some of my other videos for better refrigerant charging procedure understanding. Supervision is needed by a licensed HVAC Tech before doing this as Experience and Apprenticeship garners Wisdom and Safety.
