How to Check Superheat and Subcooling!

In this HVAC Refrigerant Charging Video I Explain how to Check and Measure the Superheat and Subcooling Charging Processes for R22 and R410A freon. I show you most importantly how to know which one to use to check a freon refrigerant level in an air conditioning and heat pump system, what it means to have high superheated, low superheat high subcooling and low subcooling. I explain the other things that affect the superheat and subcooling temperature besides the actual refrigerant charge. I go over what the blue gauge is reading along with the red gauge, how to convert pressures to temperatures, how a charge could damage a compressor, and many other details.
