An air conditioner removes moisture from the air as it cools, and that water has to drain away. When the drain clogs or a pan cracks, the overflow spills into the closet, drops through the ceiling below or runs along the hallway. Water that reaches the ceiling is handled on the ceiling leak page.
Why summer brings these leaks
This area has a hot-summer Mediterranean climate with hot, dry months, so cooling systems run hard and long. A drain that is slightly slow in June can back up completely by August, and the leak may continue for days before it is noticed.
Dealing with the water
Condensate water is not as dirty as sewage, but it can carry algae and dust. Porous materials that stay wet are removed, while drywall and framing that can dry are treated with airflow. The system is shut off until a technician clears the drain.
