The HVAC Know It All podcast is hosted by me, Gary McCreadie. These are my thoughts, my jobs, my tools....This is my HVAC life.


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!
