Can't say as I've ever seen an air filter on a
condensor. How do you keep your condensor filter
dry, when it rains or snows?

I install filters on condensers for refrigeration units
in restaurants. I explain to the owners that unless they
want to spend another $1,200.00 to replace a compressor,
wash the filter once a week. Why do people always want
to shoot the messenger? **snicker*

TDD

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?
