Low refrigerant levels can cause the evaporator coil to freeze, and when it melts, the excess water may leak. This can be a sign of a more serious issue, such as a refrigerant leak.

Condensation on the aircon flaps is also a common cause of leaks. This is mainly due to mild condensation of air from the air conditioner onto its flaps, which can be worsened by quiet mode or dirty evaporator coils.

A blockage in the drainage pipe is one of the most common reasons for an air conditioner to leak water. If the pipe is blocked, water will back up and eventually start leaking from the unit.

A problem with the condensate pump can also cause water leaks. The condensate pump is responsible for removing water from the unit, and if it's not working properly, water can start to accumulate and eventually leak out.

Here's a list of common causes of leaks:

  • Clogged drain pipe
  • Improper installation
  • Low refrigerant levels
  • Condensation on the aircon flaps
  • Blockage in the drainage pipe
  • Problem with the condensate pump

Regular maintenance, such as cleaning the filter and coil, can help prevent leaks. It's also essential to check the aircon installation guide before installing the unit.
