Cooling a house in summer pulls gallons of moisture out of the air, and all of it is supposed to leave through a small condensate drain. When algae or debris blocks that drain, the pan under the air handler fills and spills, often into a ceiling or closet where nobody is looking until a brown stain appears.
Where the overflow shows up
- A brown or yellow stain on the ceiling below the unit
- Drywall that bubbles or sags near the air handler
- Damp carpet inside a hall or utility closet
- Wet attic insulation around the unit
- A musty smell that returns after each cooling cycle
Describe the stain, the closet or the attic, and the crew explains how the overflow area would be traced and dried.
Ask about that ceiling stainDrying after an overflow
Condensate is clean at the start, yet it sits in insulation and drywall and quickly collects dust and growth. The crew extracts what has pooled, removes sagging ceiling sections and starts structural drying with air movers and a dehumidifier, with readings repeated until the ceiling cavity is dry.
Stopping repeat leaks
A cooling technician clears the drain and checks the pan and float switch, since the same overflow returns if the cause stays. Restoration covers the water damage only, so the repair and the drying are scheduled to follow one another. A stained ceiling is also covered under ceiling leak water damage.
AC Condensate and Air Handler Leaks in short
Condensate overflows soak the ceiling below an air handler, the closet around it and sometimes the attic insulation above. The crew traces the moisture, dries what is wet and removes ceiling material that has sagged.
