Question:
My AC has a clogged pipe or some such, and is leaking all over the
basement--which is unfurnished.
Answer:
condenser condenses. Otherwise, they'd call it something else.
Condensation is liquid water. The complaint was excessive liquid water
someplace where it isn't supposed to be, and there wasn't a complaint
of insufficient cooling, so my first-blush impression was that the
system designed to carry H2O(l) from where it isn't supposed to be to
where it is supposed to be is not functioning as intended. A clog is
the first thing to check, because it's the simplest to solve.
The condenser is usually indoors, because the role of air conditioning
is to remove both heat and humidity, and the condenser sucks H2O(g)
from the air and sends it out a pipe as H2O(l). A problem with the
blower wouldn't leave water on the floor. A problem with the compressor
would be outside. That leaves only one subsystem as the likely culprit.
If there's something wrong in my reasoning, feel free to point it out.
