Water & leak problems

Water leaks from an aircon indoor unit are the second most common complaint in Singapore. The unit produces condensation naturally — moisture from humid indoor air collects on the evaporator coil and drains away through a pipe. When that drainage path is blocked, water backs up and drips from the unit or tray.

A clogged drain pipe is the cause in most cases. Dust, algae, and slime build up inside the drain line over time, especially in Singapore's humidity. A simple drain flush during routine servicing prevents this. If the leak only happens when it rains, the issue is often water ingress through the wall sleeve where the pipes pass through.

Condensation forming on exposed copper pipes is different from a leak — it means the pipe insulation has degraded or was installed too thin. This is cosmetic in the short term but can cause water damage to walls and ceilings if left unaddressed.
