When your air conditioner leaks water, it can indicate several issues that need attention. Here’s a breakdown of what to do, potential causes, and repair costs:

What to Do When Your AC Leaks Water

1. Turn Off the AC – Prevent further damage by shutting down the system.
2. Check the Air Filter – A clogged filter can cause ice buildup that melts and leaks.
3. Inspect the Drain Line – A blocked condensate drain can cause water overflow.
4. Look for Ice on Coils – If present, let it thaw before turning the AC back on.
5. Check the Drain Pan – If cracked or rusted, it needs replacement.
6. Ensure Proper Installation – An uneven AC unit can cause improper drainage.
7. Call a Professional – If you can’t identify the issue, a technician can diagnose and fix it.

Common Causes of an AC Leak

• Clogged Condensate Drain Line – Dirt, mold, or debris blocking the line.
• Frozen Evaporator Coils – Caused by low refrigerant or restricted airflow.
• Dirty Air Filter – Reduces airflow, leading to coil freezing.
• Damaged Drain Pan – Rust or cracks in older units.
• Improper AC Installation – Uneven or tilted placement affects drainage.

Repair Costs

• Drain Line Cleaning: $75 – $250
• Drain Pan Replacement: $200 – $600
• Air Filter Replacement: $10 – $50
• Frozen Coil Repair: $200 – $1,500 (depends on refrigerant issues)
