Hi everyone,

I have a wall mounted air conditioner (with the compressor outside)
and recently, the air it pushes has started to take on a weird odor
(not all the time - it's intermitent). I propped myself up there and
there seemed to be a brownish liquid, like moisture, sitting on the
vents.

I washed it all up, but the smell remains ... anyone has any idea what
could be causing this? (My filters are cleaned regularly - so that's
not it).

thanks,

Max
