Last night I decided to turn on my CAC for the first time in
anticipation for the upcoming warmer weather for the next few days.
Everything seemed to be OK. The compressor came on, and the indoor
blower came on. I also checked the pipe coming out of the compressor
to see if it was cold, but it did not seem "as" cold as it should.
When I looked in the sight glass I could see the freon flowing OK.
My question is being that it was only about 68 degrees outside last
night, does that affect the operation of the CAC, and thus why the
pipe did not feel cold? I remember last year when a service guy came
over to check the A/C, he said it should be checked optimally when it
is warm outside, plus he put a plastic bag around the unit to
increase the "head " pressure so he could get a more accurate reading
on his gauges( By the way, the unit checked out OK last year.) What
does head pressure mean?
I'm just trying to educate myself a little with how CAC works . Thanks

I am going to suspect that either the unit is not performing as it
should do any many possible problems, or that it simply did not "feel" as
cool as you would expect because it was already cool and the difference was
not all that much.
