A long cooling season
Alpharetta has a humid subtropical climate, so cooling systems work for long stretches and make a lot of condensate. A drain that clogs with algae or sludge in a warm season can overflow for days before a ceiling stain or a damp closet draws attention.
Tracing the overflow
Air handlers sit in attics, closets and garages, and the water drops onto the ceiling or floor below. The drying team uses a thermal camera and a moisture meter to follow it, removes wet insulation and ceiling drywall and extracts water from carpet and flooring in the closet or hall. A leak that ran for days can also reach the walls, so the readings are taken beyond the visible stain.
Drying and preventing a repeat
Equipment dries the ceiling cavity and the floor until the readings drop to normal levels, and the crew checks again before anything is closed up. A technician clears the drain and checks the float switch that shuts the unit off when the pan fills, which stops a repeat. Slower stains from a nearby source are covered under ceiling leak water damage and structural drying.
