Two options: (the condensate IS forming on the outside)

1. don't worry about it.
2. Insulate them on the outside also.


#1 may not be an option, depending on where it is and what's underneath it.
Think finished basement with ducts above suspended ceiling tiles which will be
damaged by dripping water.

Actually it is in the crawl space under the house. There is lots of room
under there. The house is on a hill. It is typically pretty dry, however
we have had much rain this year and the rounnd under the house is damp.
Can't do much about that.
I am concerned about the duct work rusting prematurly where condensate
is forming.
