Exactly What is Superheat and Subcooling? Shown on a Live AC Unit!

This HVAC Video is- What Exactly are Superheat and Subcooling and How do you use each of them for Charging Air Conditioners to Check the Level of Refrigerant? I go over what each of these means on a live running unit. I show you what an undercharge, correct charge, and overcharge look like. I go over the exact process to check the refrigerant level regardless of the type of metering device you have. This video also shows you how to identify what charging process to use for each system that you may walk come upon as well as other tips!
