In a Florida home, the air conditioner removes a lot of water from the air, and that water has to go somewhere. Each system produces gallons of condensate a day in summer, drained through a small PVC line to the outside. When the line clogs with algae or debris, the drain pan overflows, and the water goes into the ceiling, closet, or utility room around the air handler. It is one of the most common causes of water damage in the state.
Because the leak is often slow and hidden, damage builds for days or weeks before it shows. By the time a ceiling stain appears, insulation may be soaked, drywall weakened, and mold growing in the cavity above. Our work is to extract water, remove damaged materials, dry the structure, and prevent mold. Your AC contractor handles the drain line and equipment repair.
Signs you need ac leak damage help
- Water stains or dripping near AC vents, closets, or air handlers
- A musty smell when the AC runs
- Water pooling around the indoor unit
- Ceiling drywall that is soft or sagging
- The AC shuts off unexpectedly, which can indicate a float switch tripped
- Visible slime or algae at the drain line
How our ac leak damage process works
- Shut down the ACTurn off the system until the drain is cleared; continuing to run it can worsen the leak.
- Extract waterWater is removed from floors, closets, and ceilings.
- Assess ceiling and insulationMoisture readings determine whether ceilings, insulation, and walls can be dried in place or need removal.
- Dry and treatAir movers and dehumidifiers dry the space; antimicrobial treatment protects against mold.
- Coordinate with your AC contractorThe drain line and equipment are fixed so the problem does not return.
Why this is different in Florida
Florida's AC systems run almost constantly for much of the year, which means large volumes of condensate and lots of opportunities for drain line clogs. Attic air handlers, common in Florida homes, sit above ceilings and closets; when they overflow, the water falls into living space. Many homes have secondary drain pans and float switches, but those can fail or be missing.
Condos and townhomes add another twist: a leak in one unit's air handler can drip into the unit below. If you are in a multi-unit building, an AC leak can involve your neighbors, the association, and multiple insurers.
Common causes
- Clogged condensate drain line
- Cracked or rusted drain pan
- Frozen evaporator coil that melts and overflows
- Failed float switch
- Poorly sloped or disconnected drain line
- Neglected AC maintenance
Mistakes that make it worse
- Just wiping up the water and leaving the ceiling wet.
- Skipping AC maintenance. A yearly drain line flush is cheap compared to a ceiling repair.
- Not installing a float switch or leak sensor.
- Keeping the AC running with a clogged drain.
