why does condensation drip from air conditioner vent in ceiling
Condensation from Ceiling AC Vent. Hope you guys can help. I have condensation dripping from one of my AC vents in my bedroom. It only happens on real cold weather days, the vent is in the ceiling approximately 2 feet from an exterior wall that has a sliding glass door. My assumption is that the interior warm air from the room is meeting the cold air from the attic causing the condensation - thus dripping from the vent to the floor.
