Thanks for adding meaningful information to the thread.. I didn't know the title of this forum was "You're not allowed to know, now go away".
I've said it before and I'll say it again.........

Oh yeah, and I never said everyone in HVAC are "professional".

You can log your findings all you want. All your going to find is that everytime you checked your own pressures, you lost refrigerant. And when the system fails, I highly doubt the tech that comes out will want to see your pressure log. That tell us nothing other than the compressor was pumping.

You want to start a log, go ahead. But personally, I wouldn't use a HO logbook when I go to diagnose a problem. Thats just me.

Oh and I've been trying to get the forum name changed to "We know it all.....and don't you forget it!!!"
