thanks everyone, after some more research I found a few hits that explains
the "h-valve" is in fact the expansion valve. (as some of you noted)

As for the clicking compressor, I know it's not normal, as it was an obvious
noise I noticed when I went picked up my jeep, and it was not doing that
before I dropped it off. I'm just trying to figure out what they may have
removed and/or added to the ac system during the diagnostic process to cause
the clicking. ?? anyone have any ideas? Maybe some part they checked was
not re-assembled correctly?? I did notice the florescent dye in some spots,
so I'm assuming they added the tracer liquid to try and locate any leaks,
would that stuff cause any issues?

Your A/C wasn't working before you dropped it off either.

Normal.
