What causes condensation in AC ducts? A: Condensation in AC ducts can be caused by improperly sealed openings or a lack of proper insulation around the AC duct. Condensation occurs when the outer portion of the duct work is cooled down and comes into contact with warmer air, according to Ace Plumbing.
A dirty filter will cause ice to form on the unit's evaporator coils, and when that ice melts, it drips water. The third reasonâa stopped-up condensate lineâis the most common cause of A/C leaks. The condensate line drains condensation from the overflow pan to the outside or directly into a drainpipe. When the line is clogged, water backs up and floods the overflow pan.
