What usually causes indoor AC water leaks?
Understanding the cause helps fix leaks permanently. The most frequent issues are:

Clogged condensate drain line
Algae, dust and sludge build up and block the PVC drain. When blocked, water overflows into the indoor casing or ceiling cavity.

Dirty filters & frozen evaporator coil
Restricted airflow (dirty filters/coils) can freeze the coil. When the ice melts, excess water may overflow the drain pan.

If heavy dirt or mould is the cause, a professional aircon chemical cleaning often clears coils and drains and prevents leaks from returning.
Cracked or misaligned drain pan
Age, UV exposure or previous servicing can crack or misplace the condensate tray, causing leaks in odd places.

Low refrigerant causing coil freeze
Leaks in refrigerant lines cause the coil to ice over and then drips when it thaws. Refrigerant work must be done by certified techs.

Disconnected or damaged drain pipe
Loose joints or hairline cracks in the drain piping allow water to escape along the pipe run.

Poor installation / incorrect slope
If the indoor unit or drain pipe isn’t level, water won’t flow correctly and will back up.
