AC Condensate Leak Water Damage in Melissa, TX

An air conditioner removes moisture from the air as it cools, and that water leaves through a small drain. When algae or debris clogs the drain, the pan overflows and the water finds the ceiling, a closet wall or the attic floor. The leak is slow, which lets it go unnoticed for a long time. A pan that overflows once will usually do it again until the drain is cleared, so the repair and the dry-out are best handled together.

Why these leaks hide

Air handlers often sit in the attic or a closet, so the first sign is usually a brown stain on a ceiling or a bubble in the paint. By then the insulation above is saturated and the drywall is soft. Treat any ceiling stain beneath an air handler as a possible condensate leak. Insulation above the ceiling acts like a sponge, holding water against the drywall and spreading the stain outward over time.

• Brown ceiling stain below the air handler
• Water in the drain pan or on the platform
• Soft or sagging drywall near a vent
• Musty smell after the system runs

How the damage is dried

Technicians check the pan and drain, then remove soaked insulation and open ceiling drywall that has lost strength. Air movers and dehumidifiers dry the framing and wall cavities, and readings confirm the space is ready before repairs. A heating and cooling technician clears the drain to prevent a repeat. In many cases only part of the ceiling must come down, which keeps the repair smaller.

Why speed matters

Water that sits in warm attic spaces breeds odor quickly, so drying begins promptly and moisture readings are logged for the claim. A drain cleaning and a pan check also reduce the chance of the same leak returning.
