AC Leak Water Damage in Owasso, OK

Why is your AC leaking water into the house?

Most AC leaks come from the condensate drain line. Your system makes water as it cools the air, and that water drains away through a small pipe. When the pipe clogs, the water backs up and overflows.

Clogged condensate drain line, often from algae and dirt building up

Full or cracked drain pan under the air handler

Failed or missing float switch, which should shut the AC off before it overflows

Frozen evaporator coil that melts and overwhelms the pan, often from a dirty filter

Disconnected or broken drain pipe in the attic or closet

What should you do right now?

Turn the AC off at the thermostat so it stops making water.

Catch the drip with a bucket and move furniture and electronics away.

Turn off power to any light or ceiling fan near the water at the breaker.

Stay out from under a sagging ceiling.

Take photos of the ceiling, the floor and the air handler if you can safely see it.

Call an HVAC technician to clear the drain and call us to dry the water damage.

What are the warning signs before the ceiling stains?

Most AC leaks give a warning before water comes through the ceiling. Catching these early can save the drywall and insulation.

Water dripping from a pipe outside, above a window. That's often the backup drain line, and it means the main drain is clogged.

The AC shuts off and won't cool. A float switch may have tripped because the pan is full.

Water on the floor of the AC closet or around the unit in the garage.

A musty smell from the vents.

Where does AC water damage happen in Owasso homes?

In many Owasso homes the air handler sits in the attic above a bedroom or hallway. When it overflows, water soaks the blown-in insulation and comes through the ceiling below. In homes with the air handler in a hall closet or the garage, water spreads across the floor and into the bottom of nearby walls.

How do we fix AC leak water damage?

Confirm the AC is off and the drain issue is being fixed by your HVAC technician.

Map the moisture in the ceiling, attic and walls with meters and thermal imaging.

Remove soaked insulation and ceiling drywall that's sagging or soft.

Dry the attic, ceiling and walls with air movers and dehumidifiers.

Check readings until everything is dry, then repair the ceiling.

How can you stop the AC from leaking again?

Change your air filter on schedule so the coil doesn't freeze.

Have your HVAC technician clean the condensate drain line during regular service.

Make sure a float switch is installed and working.

Watch for water dripping from the backup drain outside.

Frequently asked questions

Why did my AC stop cooling right when it started leaking?

Many systems have a float switch that turns the AC off when the drain pan fills up, so it doesn't overflow. If your AC suddenly stopped and you see water, the drain is likely clogged. An HVAC technician needs to clear it before the AC can run again.

Why is water dripping from a pipe outside above my window?

That's usually the backup drain line from the air handler's secondary pan. Water coming out of it means the main drain line is clogged. Call an HVAC technician soon, before the backup pan fills and overflows inside.

Can I keep running the AC while it's leaking?

No. Every hour it runs, it makes more water that can soak the ceiling and insulation. Turn it off at the thermostat until the drain is cleared, and use fans to stay cool in the meantime.

Is AC water dirty?

The water your AC makes starts out fairly clean, but drain lines and pans often hold algae, dust and bacteria. Water that sat in a dirty pan or soaked into insulation should be handled as more than clean water.

Does insurance cover water damage from an AC leak?

Sudden water damage from an AC overflow is often covered, but damage from a slow leak or from skipped maintenance may not be. The repair to the AC itself usually isn't covered. Check your policy. Read more about water damage insurance claims.

Can an AC leak cause mold?

Yes. AC leaks happen in summer, when attics are hot and the air is humid, so wet insulation and drywall can grow mold quickly. Removing soaked insulation and drying the area right away is what prevents it.
