I have a 2'x'2' return duct about 4' long and there is a 12" round flexduct attached to the duct in a horizontal manner. At the attachment point I can see the fiberglass as some of the outer aluminum foil has pulled away from the ductboard. Obviously a new duct would be best but how can I repair what is there now?

Really not a big deal but, if it bothers you just wrap it with duct tape. Not the type of duct tape your thinking of, use HVAC ductwork tape.
