Introduction
Your aircond is on, lights are working, but the room is still hot? That’s a clear sign something’s wrong.
Many aircond users in Malaysia experience this issue — the unit looks like it’s working (fan noise, power light on), but the air blowing out isn’t cold. This not only wastes electricity but also affects comfort, especially in hot weather. This article helps you identify the causes and when it's the right time to get your aircond serviced.

Common causes why your aircond isn’t cooling effectively:
Low or Empty Refrigerant Gas Without sufficient gas, the unit can't cool the air.
Dirty Air Filters Clogged filters block airflow, reducing cooling efficiency.
Frozen or Dirty Evaporator Coil Dirt or ice buildup disrupts heat absorption.
Faulty PCB Board or Thermostat The temperature sensor fails to regulate temperature correctly.
Compressor is Faulty or Overheating If the outdoor unit isn’t working, the cooling process stops.
Outdoor Fan Not Spinning No airflow means the system overheats and becomes inefficieDamaged ornt.

When cooling is weaker than usual
After high-usage periods (e.g., during heatwaves or Ramadan)
