If your air conditioner is leaking, not cooling, making noise, or suddenly stops working, the cause is usually Common Aircond Problems in Malaysia’s hot, humid climate and poor maintenance—not a “dead” unit.

Why Common Aircond Problems in Malaysia work harder than in many other countries due to:
- High humidity (causes water leakage & mold)
- Year-round heat (compressor stress)
- Dust, construction debris, and pollution
- Infrequent servicing (a very common client mistake)
In areas like Petaling Jaya, Shah Alam, Puchong, Subang Jaya, Johor Bahru town, Skudai, and Pasir Gudang, we often see systems fail earlier simply due to lack of preventive care.
Common Aircond Problems in Malaysia (And How to Fix Them)
1. Aircond Water Leakage (Most Common Issue)
Definition: Water dripping from the indoor unit or wall.
Common Causes:
- Clogged drainage pipe

How to Fix (Step-by-Step):
- Switch off power immediately (safety first).
- Check if water flow is blocked.
- Perform professional aircond coil cleaning.
- Flush or replace drainage pipe.
- Re-align the unit if installation is incorrect.
Safety Warning: Do not open the unit while power is on—risk of electric shock.
Local Example:
In Puchong and Setia Alam, many condos experience leakage due to hidden drain pipe clogs caused by dust and algae buildup.
2. Aircond Not Cooling Properly
Possible Reasons:
