Air conditioners pull water out of the air. When that water can’t drain, it ends up on the floor. Most leaks come from a few fixable causes.
First steps
- Turn the AC off at the thermostat to stop more water
- Mop up and protect flooring and anything stored nearby
- Check the filter and replace it if it’s dirty
Common causes
- Clogged condensate drain line (algae and debris)
- Failed condensate pump in basements and closets
- Frozen evaporator coil melting all at once
- Cracked or rusted drain pan
- Disconnected drain fitting after other work
If you see ice
Leave cooling off and run the fan to thaw it, then replace the filter. See AC frozen coil: what to do. A dirty filter froze the coil on this Magna emergency AC call.

Frequently asked questions
Why is my AC leaking water inside?
Usually a clogged condensate drain, a failed condensate pump, a frozen coil melting, or a cracked drain pan.
Should I turn off my AC if it’s leaking?
Yes. Turn cooling off to stop more water, check the filter, and look for ice on the coil or lines.
Can a dirty filter make an AC leak?
Yes. It can freeze the coil, and the ice melts into more water than the drain can handle.
