Introduction
When the aircond isn't cold, the whole house heats up
An air-con that’s on but not cooling can be frustrating—especially in Malaysia’s hot weather. But don’t panic. It’s usually caused by fixable issues.
1. Aircond Gas Is Low or Empty
When refrigerant gas is low, the system can’t produce cold air efficiently.
This often happens due to minor leaks.
Solution: Call a technician to top up the gas and check for leaks.
2. Dirty or Clogged Air Filter
Dust buildup can block airflow.
This results in weak airflow and less cooling.
Solution: Clean the filter every 2–3 weeks or request a full cleaning service.
3. Faulty Outdoor Unit (Compressor)
The compressor is responsible for generating cold air.
If it's broken or overheated, the aircond will just blow warm air.
Solution: Requires diagnosis and repair by a professional.

4. Incorrect Remote Settings
Sometimes it's just a case of wrong temperature or mode settings.
Ensure it’s set to “Cool” and below 24°C.
Solution: Check the manual or reset the remote to default.
5. Broken Thermostat
A faulty thermostat may fail to detect the correct temperature.
As a result, the aircond won't activate cooling even when it’s hot.
Solution: Replace the thermostat or fix the sensor connection.
6. Aircond Size Not Suitable for Room
If the room is large but you’re using a small aircon unit, it won’t cool effectively.
This overworks the system and can cause quicker breakdowns.
Solution: Make sure the unit’s BTU matches your room size.
7. Electrical or Circuit Issues
Tripped switches or loose wiring can affect performance.
The air cond may power on but not work properly.
Solution: Have a licensed technician inspect the wiring.
