Ductwork should be insulated, on the inside, or outside to prevent this. Wrap the areas with fiberglass, and tape the ends. If left unattended it may cause a musty smell in the ductwork.

Somewhere warm air is making contact with cold air. A small amount of moisture is not unusual during an extended period of warm weather, but once the insulation is saturated, it is not insulation any more, it becomes a conductor.
