Vacuum Police, Filter Driers, King Valves and Troubleshooting Without a Meter

On this episode I'm flying solo. We discuss the making of the Vacuum Police, and discuss filter driers. Should we upsize them or run with the OEM replacement? The King valve only exists at one place on a system and finally I did a little troubleshooting without a multimeter. Happy HVACing!
