AC Leaking Water Inside Your Home?

Understanding the Problem

Water pooling around your indoor AC unit is a common problem in Houston — and one you shouldn't ignore. Houston's extreme humidity means your AC removes gallons of moisture from the air daily. When the drainage system fails, that water ends up on your floor, in your ceiling, or causing mold growth.

Common Causes

Clogged Condensate Drain Line

This is the #1 cause. Algae, mold, and debris build up in the drain line over time, blocking water flow. Houston's humidity accelerates this problem significantly.

Cracked or Overflowing Drain Pan

Older units (10+ years) can develop rust holes or cracks in the drain pan, allowing water to leak through.

Frozen Evaporator Coil Thawing

If your coil freezes and then thaws, the sudden rush of water can overwhelm the drain pan.

Disconnected Drain Line

Vibration or improper installation can cause the drain line to disconnect from the unit.

Low Refrigerant

Low refrigerant causes the evaporator coil to freeze. When it thaws, excess water overflows the drain pan.

When to Call a Pro

If clearing the drain line doesn't stop the leak, or if water is coming from an unusual location, call a professional. Water damage can lead to mold growth within 24-48 hours in Houston's humidity.
