I've never seen a filter, on a residential AC
condensor. How do you keep your condensor
filter
dry, when it rains or snows?

I use medium size/opening filters, not the
el-cheapo fibreglass ones
that are almost totally open, but not the real
fine particle types
either. I change them once a month if I remember
to. They are always
dirty looking if you hold them up to the light.
They keep loose dirt
from entering the blower and then maybe clogging
the A-frame air-
conditioning condensor coils

I don't understand cleaning ductwork. If the ducts
start out clean and
then gradually accumulate dirt, that dirt either
stays put, or blows
out into the room. If they start out clean, and
you have a filter, how
does the ductwork get dirty? And, if it is dirty,
once the loose
dirt blows out, how does more loose dirt occur to
get blown out. That
new loose dirt will get blown out whether the duct
is clean or has a
build-up of dirt that isn't loose, so cleaning the
ductwork is only
needed if it gets so bad that it impedes air-flow.
What am I missing
besides enriching all the ductwork cleaning firms?
