1. Clogged Drain Pipe
The most common cause of a leaking aircon in Singapore is a choked condensation line. Dust and dirt build up over time, blocking the water flow.
2. Dirty Air Filter
If the filter is dirty, the evaporator coil freezes. When it melts, it overflows the drip pan.
3. Low Refrigerant (Gas Leak)
Low gas causes the system to freeze up. You will need a professional technician to top up the gas and seal the leak.
4. Rusted Drip Pan
Older units (over 5-7 years) might have a rusted or cracked drip pan.
When to call a professional?
If clearing the filter does not work, you likely need a professional chemical wash to clear the jelly in the drainage pipe.
