AC & HVAC Leak Water Damage Cleanup in McDonough, GA
Ceiling stain under the attic unit? Water around the AC closet? In a Georgia summer, an overflowing condensate line can soak your ceiling for days. Local AC leak water damage technicians dry it before mold moves in.
AC leak water damage in McDonough, GA happens when an air conditioner's condensate system overflows: a clogged drain line, a full or rusted drain pan, a failed float switch or a frozen evaporator coil. In most Henry County homes, the air handler sits in the attic or a hallway closet, so the water lands in insulation, ceiling drywall or flooring before anyone notices. Water damage technicians dry the attic, ceiling and walls, remove what can't be saved and treat for mold, while your HVAC technician fixes the unit.
Air conditioners here run for much of the year, pulling a lot of water out of humid air every day. That's why AC overflows are a distinctly Georgia cause of water damage restoration in McDonough homes, peaking from late spring into early fall.
Why Is My AC Leaking Water into the Ceiling?
- Clogged condensate line. Algae, dust and sludge build up in the PVC drain line until water backs up.
- Full or rusted primary drain pan under the air handler overflowing or leaking through.
- Missing, rusted or blocked secondary (emergency) pan in the attic, so overflow goes straight into the ceiling.
- Failed or missing float switch that should shut the system off when water rises.
- Frozen evaporator coil from low refrigerant or a dirty filter; when it thaws, it releases more water than the pan can hold.
- Sweating ductwork in a hot, humid attic dripping onto insulation.
- Disconnected or cracked drain line after attic work.
AC Leaking? What to Do Right Now
- Turn the AC off at the thermostat, and at the breaker if water is near electrical parts.
- Move belongings away from the drip and catch the water.
- Check the drain pan in the attic or closet if it's safe to reach. A full pan confirms the condensate system is the source.
- Don't run the AC until the drain is cleared; it will keep producing water.
- Photograph the pan, unit and ceiling damage.
- Call your HVAC technician for the unit and call us for the water damage.
Attic Air Handlers and Closet Units: Where the Water Goes
| Unit location | Typical damage |

| Hallway or utility closet | Wet carpet and pad, swollen baseboards, water under nearby flooring and walls |
| Garage | Water on the slab and at the base of adjoining walls |
| Crawl space | Water pooling on soil, soaking joists and insulation (see crawl space water damage) |
AC Water Damage and Mold in Georgia Summers
AC leaks create the perfect setup for mold: warm attics, wet insulation, and moisture hidden above the ceiling where no one looks. Insulation that stays wet can hold moisture against drywall for weeks. If you notice a musty smell when the AC kicks on or dark spots around ceiling vents, the moisture may already be feeding mold, and our mold remediation service can handle it during cleanup.
HVAC Technician or Water Damage Team: Who Handles What?
Your HVAC technician fixes the cause: clearing the drain line, replacing pans, installing a float switch or repairing a frozen coil. A water damage restoration crew handles the effect: drying the attic, ceiling, walls and floors, removing wet insulation and drywall, and preventing mold. Both can happen the same day, and drying shouldn't wait until the AC repair is finished.
How AC Leak Water Damage Is Dried
- Moisture mapping of the ceiling, attic, closet and nearby walls with meters and thermal imaging.
- Remove wet insulation and any sagging or soaked ceiling drywall.
- Dry joists, top plates and wall cavities with our structural drying equipment.
- Extract water from carpet and floors around closet units.
- Antimicrobial treatment of affected framing.
- Restore insulation, drywall, texture and paint.
Does Insurance Cover AC Leak Ceiling Damage?
Sudden water damage from an AC overflow is often covered, but the AC repair itself usually isn't, and damage from a long-term, neglected drain problem may be denied as maintenance. Photograph the unit, pan and damage, and keep your HVAC repair invoice.

AC Leak Questions from McDonough Homeowners
Is an AC water leak an emergency?
It can be. Water above a ceiling spreads through insulation and can make drywall sag or fall. Turn the AC off and get the area dried quickly.
Can AC condensation cause mold?
Yes. Wet insulation and drywall in a warm attic are ideal for mold, especially in Georgia's humid summers.
Why does my AC leak only in summer?
That's when the system removes the most moisture from the air, so a partly clogged drain line finally overflows.
Can I keep running my AC while it's leaking?
It's best not to. Running the AC keeps producing water. Turn it off until the drain is cleared.
How do I know if the leak is from the AC or the roof?
If it happens without rain, near the air handler, and the drain pan is full, it's almost always the AC.
