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.
Why Is Excessive Condensation in My Air Conditioner a Problem? You are probably familiar with the sounds an AC makes during normal operation: the whir of the blower, the hum of the compressor, and the occasional sound of dripping water. The source of that last sound is the condensation that develops along the evaporator coil. As warm air flows across the coil, the coil absorbs heat and also collects moisture. This moisture then drips down into a condensate pan, where a drain and pump remove it down a line toward the wastewater system of your plumbing.
