Air conditioner leaks usually come from a clogged condensate drain line or a failed drain pan. Turn off the AC, stop the leak and call for drying. An HVAC technician clears the line while a restoration company dries ceilings, attics and walls.
What ac leak water damage involves
Houston air conditioners run most of the year and produce gallons of condensate every day. When the drain line clogs, water backs up into the pan and overflows into the attic or closet.
Because many attic air handlers sit above bedrooms and hallways, a slow condensate leak can saturate insulation and stain ceilings before anyone notices.
Signs you may need this service
- Stain on a ceiling below the air handler
- Water in the drain pan
- AC stops working because a float switch trips
- Musty smell from vents
- Damp insulation near the attic unit
What happens step by step
- Turn off the AC at the thermostat and breaker
- Clear standing water from the pan if safe
- Call an HVAC technician to clear the drain line
- Call for ceiling and attic drying
- Replace wet insulation
- Repair the ceiling after it is dry
Why this matters in Houston
Install a secondary drain pan with a float switch above living space and flush the condensate line with vinegar on a regular schedule, as HVAC technicians recommend.
Mistakes that make damage worse
- Running the AC while the pan is overflowing
- Ignoring small ceiling stains
- Skipping the attic inspection
- Not using a float switch
Cost considerations
Drying and ceiling repair depend on the wet area. HVAC service is separate. Many policies treat sudden overflow as covered and long term seepage as excluded.
