Well, what I read that applied to me was that poor airflow (dirty filter,
bad fan belt, ductwork blockage), low refrigerant or a leaking coil
would cause freezing. I didn't take the cover off a running system to see
that they were iced. There was freezing on the refrigerant line right
where it begins to enter the coil, which is visible without removing
anything. After running it for a bit and not getting any cold air, I
removed the panel and found further icing inside.
I simply wanted to ensure there was no simple thing I was overlooking. I
like to be informed about how things work, what causes problems and
generally be informed when a technician arrives. It doesn't matter if
it's my HVAC, my car or anything else. I know when I'm in over my head
and need to hire a professional, which I intend on doing first thing in
the morning. I didn't realize that wanting to be informed was such a
crime around here.
