How to Use a Refrigerant Gauge Set STEP BY STEP to Read Superheat for R-410A!

How to Use a Refrigerant Gauge Set STEP BY STEP to Read Superheat for R-410A. This is how to use a manifold set to check the Refrigerant Charge of a single-speed R-410A air conditioning system if you have a piston or a capillary tube. I show you what a system would read if it is low on refrigerant and also if it is overcharged. I go over tips like evaporator freezing and why an overcharge is dangerous for these systems while also running higher wattages (less efficiently).
