Aircond Leaking Water in Semenyih? Causes & What To Check

Water dripping from your aircond can damage ceilings, walls and furniture if ignored. Many Semenyih homeowners only notice the issue after water stains appear.

An aircond leaking water is usually caused by drainage or internal airflow problems, not just “old unit”.

Here are the common causes.

1️⃣ Clogged Drain Pipe

The most common reason is a blocked drainage pipe.

When dust and dirt accumulate, water cannot flow out properly and starts overflowing inside the unit.

This often happens when regular maintenance is delayed.

2️⃣ Dirty Coil Causing Ice Formation

If airflow is restricted, the evaporator coil may freeze.

When the ice melts, excess water forms and begins dripping.

This usually means the unit needs proper cleaning.

3️⃣ Low Refrigerant (Gas Leak)

Low gas pressure can cause the coil to freeze, leading to water leakage when it defrosts.

If leakage keeps happening even after cleaning, refrigerant levels should be checked.

4️⃣ Improper Installation or Tilt

If the indoor unit is not installed at the correct angle, water may not flow properly towards the drainage pipe.

This is more common in newly installed units.

5️⃣ Cracked Drain Pan

In older units, the internal drain pan may crack, causing water to leak directly from the casing.

This usually requires part replacement.

When Should You Call a Technician?

You should seek inspection if:

• Leakage continues after basic cleaning
• Water drips from the front panel
• The ceiling becomes stained
• The unit is over 8 years old

Ignoring leakage can lead to more expensive ceiling repairs.

Final Advice for Semenyih Homes

Due to humidity and dust levels in Semenyih, routine maintenance reduces the risk of leakage.

If your aircond is leaking water, early inspection prevents bigger damage.
