Aircon water leaking from indoor unit repair
Water dripping from an aircon unit, staining the ceiling, or pooling under the unit is usually caused by a choked condensate drain pipe, a clogged or overflowing drain pan, improper unit installation (fall of the drain pipe), or a frozen coil that melts and overflows during operation. Left alone, this can damage ceiling plaster, paint, or flooring below.
A repair visit involves clearing the drain line (often with a small pump or by physically unclogging it), checking the drain pan and tray for cracks, and checking whether low refrigerant or a dirty filter is causing coil icing that leads to the leak. If the piping was installed with insufficient slope, that may need correcting rather than just cleared.
This is a fault repair rather than a scheduled maintenance clean, and it is usually urgent because of the ongoing water damage risk.
What it costs
A straightforward drain clear is a quick job. Cost increases if the drain pan or tray needs replacing, if the piping needs re-laying for proper fall, or if the leak is a symptom of a bigger refrigerant or coil-icing problem that needs separate repair.

FAQ
- Why is my aircon leaking water inside the house?
- Usually a blocked or poorly sloped condensate drain pipe, a cracked drain pan, or ice on the coil melting faster than the drain can clear it.
- Is a leaking aircon an emergency?
- It is not dangerous, but water damage to ceilings and walls gets worse the longer it runs, so most people book this within a day or two rather than waiting.
- Can I just place a container under the leak until I get it fixed?
- That stops the immediate mess but does not fix the cause, and running the unit with a blocked drain can lead to more water backing up into the unit itself.
