Can You Really Check a Refrigerant Charge without Gauges?
In this HVAC Training Video, I go over if you can really check a refrigerant charge level on an air conditioner with just a K-type temperature probe and without gauges. I go over where the saturated states are located, how to verify their location, where to mount your temp probes. I discuss the locations where you can measure superheat and where you can read subcooling.
