Finding Target Superheat to Check the Charge of an R-410A AC Unit!

In this HVAC Video, I Show How to Find The Target Superheat on an R-410A Air Conditioner with a Piston Fixed Orifice Metering Device. I show how to Compare the Target Superheat to the Actual Superheat while Checking the Refrigerant Charge with Compound and Digital Manifold Gauge Sets. A Psychrometer is Needed to Find the Wet Bulb Temp for Target Superheat. I explain how to determine if the unit is undercharged, overcharged, or correctly charged.
