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.
So, quite simply, condensation is caused when moisture-laden air comes into contact with a cold surface âthe air is cooled to a point where it can no longer hold its burden of water vapour. At this point, (DEWPOINT), water begins to drop out of the air, and it is seen as condensation on surfaces. On impervious surfaces such as glass and paint, beads or a film of water collect, but on permeable surfaces such as wallpapered and porous plaster the condensing water is absorbed into the material.
