AC Leaking Water Inside the House
Learn about the most common AC problems in Atascocita and how to address them for optimal performance.

Water under the indoor unit or from a ceiling near the air handler is usually condensate that is not draining. In humid Atascocita summers this is a frequent emergency call.
Common causes of indoor AC water leaks
- Clogged condensate drain line — Algae and debris block the PVC drain; water backs up into the pan and overflows.
- Failed or stuck float switch — The safety switch should shut the system off before overflow; if it fails, water spills.
- Dirty filter / frozen coil — Ice melts and can overwhelm the drain pan.
- Cracked or unlevel drain pan — Older pans can crack or tilt.
- Disconnected drain — Vibration or poor installation can separate the line.
Safe steps while you wait for service
- Turn the system off to limit further water.
- Protect flooring and furniture.
- If you can safely access the secondary drain or pan, note standing water for the technician.
- Do not pour chemicals into the drain without guidance — some products can damage components.
Professional fix
Technicians clear the drain, test the float switch, check the pan, and confirm the system removes humidity correctly. Recurring clogs often need a clean-out tee or annual flush as part of maintenance.
