24/7 AC Leak Water Damage Cleanup in Acworth, GA

Why does an Acworth AC unit leak water through the ceiling in summer?

Attic air handlers produce gallons of condensate daily in humid Georgia summers; a clogged drain line or rusted pan overflows straight onto the ceiling.

Most two-story Acworth homes have the air handler, the indoor part of the AC, in the attic. As warm, humid air passes over the cold coil, water condenses and drips into a pan, then drains out through a condensate line. Acworth's long, humid cooling season means that system runs hard for months. When algae or debris clogs the line, or the pan rusts through, water has one place to go: down.

AC Leak Quick Answers

Main cause

a clogged condensate line or overflowing drain pan in the attic

When it happens

most often in summer when the AC runs constantly

First sign

a brown stain or drip on the ceiling near the air handler or a hallway

First step

turn the AC off at the thermostat to stop condensate production

What gets damaged

attic insulation, ceiling drywall, sometimes walls and floors below

Mold risk

high, because attics are warm and the water keeps coming daily

Clogged condensate line: the number one cause

A clogged condensate line is behind most AC leaks. Over time, algae, mold, dust and debris build up inside the PVC drain line until water backs up into the pan. Signs of a clogged condensate line:

• Water pooling around the air handler
• A full or overflowing secondary pan
• The AC shutting off on its own (if a float switch is installed)
• A musty smell near vents
• Water dripping from the outside drain pipe slowing or stopping

HVAC technicians clear the line, often with a wet vac at the outside end or a cleaning flush. A float switch shuts the system down before the pan overflows.

Drain pan overflow in the attic

• Attic air handlers usually have two pans: a primary pan built into the unit and a secondary pan underneath. A drain pan overflow happens when:
• The primary line clogs and the secondary pan fills
• The secondary pan is rusted, cracked or has no drain line
• The unit isn't level, so water spills over one edge
• The float switch is missing or failed

Old galvanized pans in 1990s Acworth homes often rust through. A drain pan overflow can soak insulation for days before the stain shows on the ceiling.

Ceiling drip from AC: what to do

• Turn the AC off at the thermostat to stop making condensate.
• Put a bucket under the drip and move furniture and electronics.
• Turn off power to any ceiling lights or fans in the wet area.
• Don't poke a sagging ceiling; move people out from under it.
• Call an HVAC tech to clear the line, and call for water damage cleanup.
• A ceiling drip from AC usually means the attic insulation above is already soaked, so the attic needs to be checked, not just the ceiling.

HVAC water leak in Acworth: where water ends up

An HVAC water leak in Acworth can also come from sweating ducts in humid attics when insulation around them is missing or torn.

Mold risk from AC leaks

AC leaks are a mold magnet: the attic is warm, the insulation holds water and condensate keeps coming every day the AC runs. Mold can grow on ceiling drywall, roof decking and framing near the air handler. A musty smell from vents is a warning sign. See mold remediation in Acworth

How to prevent AC leaks

• Have the AC serviced each spring before cooling season
• Flush the condensate line a few times a year
• Install a float switch to shut the AC off if the pan fills
• Replace rusted secondary pans and make sure they drain
• Change air filters regularly to keep the coil clean
• Check the outside condensate drain is flowing on hot days

How much does AC leak water damage cost in Acworth?

A small stain caught early may only need attic drying and a little ceiling repair. A leak that soaked insulation across a large area and brought down ceiling drywall costs more, often within the typical $1,400 to $3,800 range for mitigation and repairs. Mold treatment adds to it.

Is AC leak damage covered by insurance?

Sudden water damage from an AC overflow may be covered, but many policies exclude damage from lack of maintenance or long-term leaks. The AC repair itself is usually not covered. See water damage insurance claim help in Acworth
