Aircon not cooling is one of the most common problems faced by homeowners and tenants in Kuala Lumpur.
Due to heat, humidity, and daily usage, air conditioning systems may lose cooling efficiency for various reasons.
Below are the most common causes of aircon not cooling properly and when professional repair is required.
Low or leaking refrigerant gas
Gas does not normally run out. If cooling is weak, it often indicates a leak in the system. Refilling gas without fixing the leak only provides temporary relief.
Dirty air filters or coils
Clogged filters and dirty evaporator coils restrict airflow and reduce cooling efficiency. Regular cleaning helps prevent this issue.
Faulty compressor
The compressor is the heart of the aircon system. If it fails or weakens, cooling performance drops significantly and professional repair is required.
Blocked or leaking drainage system
Blocked drainage can cause internal issues and affect cooling. In Kuala Lumpur’s humid climate, this problem is very common.
Electrical or sensor problems
Faulty sensors or electrical components can cause incorrect temperature readings and poor cooling performance.
When should you call an aircon technician?
If your aircon is blowing warm air, cooling unevenly, leaking water, making unusual noise, or showing error codes, professional inspection is recommended to prevent further damage.
