Anyone ever hear of spraying water from a garden hose on an A/C
condensor unit to make it cool more efficiently? A maintenance guy
where I work said that it would help. Is he pulling my leg ?

Yes, it'll help. But you'd get tired standing there, your water bill
will go up, and if you do it fulltime, harmful mineral deposits
from the tap water will render the cooling fins less effective.

Lots of times.

It can under the right conditions increase the effective capacity and
efficiency of the A/C. It also can reduce both as mineral deposits build
up. In addition there is the cost of the water and equipment.

Back in the dark ages of the 1960s and earlier, some outside units
actually had a misting system built in, when water was cheap and
plentiful. Given that today's units are designed to cool without
water, I'd leave it alone. If the compressor blew up, and you tried to
get it repaired under warranty, I'm sure the company would claim you
destroyed it with water. (But you could spray the coils a couple of
times during the cooling season to clean any dirt off and make the heat
transfer more efficient.)

I have thought about putting a small pump and catching the condensate
and misting with that. Key would be misting, any large quantitiy of
water will bog the fan, and may not do you any good.
