Question:
We just had a new central air conditioner installed. I was looking at it
outside today and noticed water dripping/leaking from the unit and the one
copper pipe running into the house.
I don't recall ever seeing this happen with the air conditioner we had at
our old house.
What is happening? Should I contact the installers?
Answer:
You are most likely describing condensation which occurs on a
cold surface in a relatively humid environment. You unit has a
small diameter very hot copper pipe and a much larger diameter
cold copper pipe. Usually most of the larger diameter cold pipe
is covered in foam insulation, but the uninsulated portions will
"sweat", especially if it is pretty humid outside.
This is common, but phone the installer if you feel the need for
reassurance. Don't expect a tech to come out for your concern
unless you describe something very different from what I've just
described.
