Package Unit Refrigerant Checks (Getting Started)

This is a video to follow up on the previous one where I tried to show how to start evaluating the refrigerant numbers and/or system performance. There are many ways to do this and this one is just mine. I have tagged in a couple of cards (to refer you to those older videos in case you wonder just where I am coming from). Of course, I know that long-windedness of my videos so the chapters should help anyone who wants to skip around to other parts of the video.
