Quick and Easy Refrigerant Charge Check with Digital Gauges! SMAN460

In this HVACR Training Video, I show How to Use the SMAN460 Digital Manifold Gauge Set with Temperature Clamps to Check the Refrigerant Charge on an Air Conditioner that has a TXV Thermostatic Expansion Valve as a Metering Device. I show how to Read Superheat and Subcooling to make sure the system is operating correctly. I discuss how to recover freon and add R-22 to charge the unit!
