HVAC condensate leaks

AC Leak Water Damage Cleanup in Atlanta, GA

A clogged condensate line can drip into your ceiling for weeks. We find the wet drywall and insulation and dry them before a stain becomes mold.

In an Atlanta summer your AC pulls gallons of water out of the air every day, and that water is supposed to leave through the condensate line. When the line clogs with algae, the pan rusts through or a frozen coil thaws, the water spills into the attic, a hall closet or the crawlspace instead, a little at a time. AC leak water damage in Atlanta usually shows up as a ceiling stain under the air handler, and by then the insulation above it has often been wet for days.

We go up into the attic or down into the crawlspace instead of just looking at the stain. Moisture meters and thermal imaging show how far water spread across the drywall and joists and whether insulation has to come out. We remove soaked insulation and damaged ceiling, set air movers and dehumidifiers, and look for early mold, which does well in a warm, damp attic. Sweating ductwork in a crawlspace gets the same check.

Fixing the line, pan or coil belongs to an HVAC technician, and we can recommend one. We handle the water damage and document it with photos and moisture readings. Insurers often treat slow condensate leaks differently from sudden ones, so a clear record of what failed and when it was found matters. Once everything is dry, we coordinate ceiling and paint repairs. Learn about insurance and billing.

Call us if you notice

  • A brown ring or bubbling paint on the ceiling under the air handler
  • Water sitting in the secondary drain pan in the attic
  • An AC that shuts itself off when the pan float switch trips
  • Damp carpet or baseboards around an indoor HVAC closet
  • A musty smell when the system kicks on
  • Water dripping from a supply vent or ceiling register

Right now, if it's safe

  1. Set the thermostat to Off so the system stops making condensate.
  2. Put a bucket under the drip. If the ceiling bulges, keep everyone out from under it.
  3. Turn off any ceiling light or fan near the wet spot at the breaker.
  4. If you go into the attic, stay on the joists. Wet drywall will not hold your weight.
  5. Move furniture and electronics away from the wet area and photograph the stain.

How we handle ac leak water damage

  1. 01

    Inspect the source

    We look at the air handler, pans and drain line in the attic, closet or crawlspace, not just the stain below.

  2. 02

    Map the moisture

    Thermal imaging and meters show how far the water spread across drywall, joists and insulation.

  3. 03

    Remove wet insulation

    Soaked blown or batt insulation holds water against the ceiling. We bag and remove it so the cavity can dry.

  4. 04

    Dry and dehumidify

    Air movers and LGR dehumidifiers bring the ceiling and framing to dry readings, even in a hot attic.

  5. 05

    Check for mold

    We inspect framing and the back of the drywall for growth. If we find it, we contain and remove it before repairs.

Why Atlanta calls Mitigate First

We go into the attic

Most stains come from water that spread well past the drip. We inspect at the source so nothing wet gets painted over.

Set up for Atlanta humidity

Hot attics and damp crawlspaces dry slowly here. We size dehumidification to the actual conditions and confirm it with readings.

Clear handoff to HVAC

We tell you exactly what failed so your HVAC tech can fix it, and we take care of everything the water damaged.

I had a great experience with Mitigate First. They were professional, responsive, and easy to work with throughout the process. It’s not always easy to find a company you can trust when dealing with water damage, but they made the experience much less stressful. I really appreciate their hard work and would definitely recommend them to anyone in need of their services

Called Mitigate First for a flood restoration job and they were on-site fast, walked me through exactly what needed to happen, and had the water out and the space dried properly without any surprises. Pricing was fair and clear up front — no padding, no change orders. Would use them again and already have them saved as my go-to.

Had a leak in my bathroom, and Mitigate First came out immediately and was great! Levi and Moysh were awesome! They are super knowledgeable and professional, and helped me through the whole process. Definitely recommend!

Questions

AC Leak Water Damage FAQ

Why is my AC leaking water into the ceiling?

Usually the condensate drain line is clogged with algae or debris, so water backs up and overflows the pan. A rusted pan, a disconnected line or a coil that froze and thawed can do the same. Your HVAC tech fixes the cause, and we deal with the wet ceiling and insulation.

Is AC leak damage covered by homeowners insurance?

It depends on your policy and how long the leak went on. Carriers often separate sudden discharges from slow, ongoing leaks. We document the source, the extent and the drying so your adjuster has a clear picture.

Can a small ceiling stain hide bigger damage?

Yes. Water spreads across the top of the drywall and soaks into insulation before it shows below. A stain the size of a plate can sit under a much larger wet area. Thermal imaging shows us the real size.

How fast can mold grow after an AC leak in Atlanta?

Wet drywall and insulation in a warm Atlanta attic can start supporting mold within 24 to 48 hours. Slow AC leaks often go on longer than that before anyone notices, which is why we check for growth on every one of these jobs.

Do I need new ceiling drywall?

Not always. Drywall that dries quickly and is not sagging can often stay. Drywall that sagged, crumbled or grew mold has to come out. We test before we decide and show you the readings.
