AC Condensate Leaks in Seminole, FL

In Pinellas County the air conditioning runs most of the year, and every hour it runs the air handler pulls water out of the humid air. That condensate drips into a pan and leaves through a PVC condensate drain. Algae and sludge grow inside that drain, and once it clogs, the pan fills and spills.

Where AC condensate leaks show up in Seminole homes

• Hall closet air handlers: water under the closet door and into the hallway carpet or tile
• Garage air handlers: water on the slab that runs under the wall into the house
• Attic air handlers: wet insulation and a stain spreading across the ceiling below
• Condos: water from one unit's air handler closet reaching the unit below

Many of these leaks are slow. A pan that overflows a little each cooling cycle can wet a closet floor, the bottom of the wall and the baseboards for weeks before anyone notices a smell or a stain.

How AC condensate leak cleanup works

The tech who does the walkthrough checks the closet, the walls on either side and the ceiling below the unit with meters and thermal imaging. Wet carpet pad and baseboards come out where needed, and wet attic insulation gets bagged and removed. Air movers and dehumidifiers then dry the floor, the wall cavities and the ceiling drywall to readings.

The water from a condensate pan is usually Category 1 when fresh, but water that sat in a slimy pan or soaked into materials for days is treated as Category 2. That changes what can be dried and what comes out.

Signs an AC condensate leak is already causing damage

Slow condensate leaks often show up as:

• A musty smell in a hallway or near the air handler closet
• Swollen or stained baseboards next to the closet
• A brown ring or bubbling paint on the ceiling under an attic unit
• Water in the secondary pan, or a float switch that keeps shutting the system off

Rooms next to the air handler closet often share a wall cavity with it, so the tech checks those walls even when the floor looks dry.

Keeping the condensate drain clear

An HVAC technician clears the clog and checks the float switch, which shuts the system off when the pan fills. Regular drain cleaning and a working float switch prevent most repeat leaks.
