"Hydronic" A/C in an enclosed overhead space condensing and weeping ruining the ceiling tiles. Answered
In an historic building, a remodel installing a chill water A/C air handler into a ceiling space now completely enclosed, is experiencing severe condensation and weeping onto the drop ceiling tiles.
I suspect a building code violation; "non vented installation". I am guessing a small powered fan/blower, cycling the air in the over head enclosed space with the "air-conditioned" environment. I am just guessing... I would be honored to receive expert advice.
