Why condensate leaks are so common in Franklin
Franklin summers are hot and humid, and many homes built from the 1990s on put the second air handler in the attic above bonus rooms and bedrooms. On a muggy day an air conditioner can pull several gallons of water out of the air. That water drains through a small PVC condensate line. When the line clogs with algae and sludge, the primary pan overflows into a secondary pan, and when the secondary pan has no float switch, a failed switch or a rusted bottom, the water goes into the ceiling.
- Algae and sludge clogs in the condensate drain line
- Rusted or cracked secondary pans under attic units
- Float switches that were never installed or have failed
- Frozen coils that dump a large volume of water when they thaw
How the damage is dried
Condensate leaks are usually slow, so by the time a stain appears the insulation around the air handler has often been wet for days. The tech who does the walkthrough maps the attic and the ceiling below with thermal imaging and meters. Soaked insulation and ceiling drywall that has sagged come out; damp drywall and framing are dried in place with air movers and dehumidifiers.
The drying team takes readings daily until the ceiling, joists and any walls the water ran down reach the drying goal. The Department of Energy air conditioning page covers routine maintenance, including keeping the condensate drain clear.
Pour a cup of white vinegar down the condensate line access each spring and fall, and make sure the secondary pan has a working float switch.
The HVAC repair and the claim
An HVAC tech clears the line, replaces a rusted pan and adds or repairs the float switch; restoration handles the water damage it caused. Because condensate leaks are often slow, insurers look closely at how long the leak ran, so the moisture map and timestamped photos matter. Related work is on ceiling leak water damage, and the EPA moisture information explains why damp insulation should not be left in place.
