Yep. Of course John can read a P-T chart so he's probably ready to go to
Carrier and redesign the entire mechanical refrigeration cycle.....I mean if
you can read it, it must surely mean you can do it. Right John?

Do you know how to read a set of guages John? Can you convert to
superheat? Do you have a clue about wet bulb? Secondly if you need to
ask if current draw provides any indication of the systems components
condition, then you are apparently also have no business with an
amprobe.

Golly, that sure is technical! I could NEVER understand that! I would
have
thought there is a chart or something I could reference to see if the
system
had the proper charge or was pulling the proper current; I had no idea I
had
to know everything about HVAC theory to read some gauges! Those needles
pointing to numbers, how in the would would anyone ever figure out what
they
mean?
