Your air conditioner works hard to keep your home or office cool — especially under Malaysia’s hot and humid weather. But like any machine, your AC system can develop problems over time.
Knowing the common aircond issues (and how to fix them) can save you from costly repairs and discomfort.
1- AC Not Cooling Properly
Problem: Your air conditioner is running, but the air feels warm or not cold enough.
Causes:
- Dirty filters or coils
- Low refrigerant (gas) levels
- Blocked condenser unit
How to fix:
Start by cleaning the air filters and evaporator coils. If cooling is still weak, your AC might need gas refilling or leak repair — something best handled by a professional.

2- Strange Noises
Problem: You hear rattling, buzzing, or screeching sounds from your AC.
Causes:
- Loose fan blades or screws
- Worn-out motor bearings
- Dirty fan or compressor
How to fix:
Turn off the unit and inspect for any loose parts or visible debris. If the noise continues, call a technician to inspect the motor or fan assembly.
Ignoring these sounds can lead to expensive compressor damage.
💡 Tip: Schedule regular aircond servicing every 3–6 months to avoid noise issues.

3- Water Leakage
Problem: Water dripping from your indoor unit can cause wall stains or mold.
Causes:
- Clogged or damaged drainage pipe
- Dirty coils
- Improper installation
How to fix:
Turn off your AC and check the drainage pipe for blockages. Clean it using a vacuum or mild pressure water. If the leak continues, you’ll need expert help to reinstall or service the drainage system.

4- Bad Odor
Problem: Your AC releases a musty or unpleasant odor when turned on.
Causes:
- Mold or bacteria buildup in the unit
- Dirty filters or stagnant water in the drain pan
How to fix:
Remove and clean your filters using mild detergent and water. Use antibacterial spray for coils and vents. If the smell persists, a deep chemical cleaning might be necessary.

5- High Electricity Bills
Problem: Your AC refuses to start even when the power is on.
Causes:
- Faulty capacitor or circuit board
- Tripped breaker
- Loose wiring
How to fix:
Check your home’s fuse or circuit breaker first. If everything looks fine, it’s time to call an aircond technician to inspect internal electrical components.
