A leaking air conditioner is one of the most common issues Singapore homeowners face. High humidity combined with frequent usage causes condensation lines to accumulate dirt, algae, and dust over time.

Why is your aircon leaking water?

When warm air hits the cold evaporator coils, moisture condenses and drips into the drainage pan. If the drainage pipe is choked with slime or debris, water backs up and overflows straight into your room.

Primary causes of aircon leaks in Singapore

  • Clogged drainage pipe: Jelly-like algae buildup blocking normal water flow.
  • Dirty air filters: Restricted airflow causing evaporator coils to freeze and melt excessively.
  • Low refrigerant gas: Sub-optimal pressure forming ice layers that melt rapidly.

Immediate steps to take when water starts dripping

First, turn off the air conditioning unit immediately to prevent electrical shorts or water damage to your walls and wooden floors. Place a container or dry towel directly underneath the leak.

Avoid using harsh chemical drain cleaners through the indoor vents, as these can corrode internal copper pipes and plastic drainage trays. A professional vacuum clearing or chemical wash is the safest method to restore proper drainage.

How regular servicing prevents unexpected breakdowns

Routine quarterly maintenance ensures your fan coil unit is thoroughly cleaned, electrical contacts are inspected, and gas pressures are calibrated. This keeps your monthly electricity bills low and extends the operational lifespan of your system.
