Ceiling sweating in summer time.

[breasons]

In my bedroom in the summer time when its hot I run a small window AC.Around the ceiling tiles and molding there is moisture.What would cause this?

where there is moisture with an air handling system the culprit is a [difference of temperature."inside an airconditioner, the suction line is always colder than the surrounding air - that's why it drips water. outside of the airconditioner the discharge air is colder than its surroundings - that's why you see moisture. must be your airconditioner is set to max cold. throttle it down a bit.
