When your aircon runs but fails to cool the room, multiple factors could be responsible—such as a failed capacitor, gas leak, dirty coil, or faulty thermistor. We conduct targeted diagnostics to locate the cause and restore chilling power.

Questions & Answers
Frequently Asked Questions
Why is my aircon blowing warm air suddenly?
This usually happens due to low refrigerant levels, a failed run capacitor, or a dirty evaporator coil restricting air transfer.
Why is my aircon blowing warm room air despite running for hours?
Warm airflow usually results from a outdoor compressor failing to turn on (due to a blown capacitor or PCB fault), severe refrigerant gas loss, a failed thermistor sensor misreading room temperature, or choked cooling coils.
How can a faulty capacitor cause my aircon to stop cooling?
The capacitor gives the outdoor compressor motor the electrical boost needed to start up. If the capacitor fails, the indoor fan will still blow air, but the outdoor compressor won't turn on, resulting in warm air output.
Can extremely dirty filters or coils prevent an aircon from cooling?
Yes. When filters or coils are caked with thick dust, air cannot pass across the aluminum fins to exchange heat. The system becomes choked, coil temperatures drop to freezing point, and airflow becomes weak and warm.
How quickly can a non-cooling aircon issue be resolved?
Most common causes—such as capacitor replacements, thermistor changes, gas top ups, or flushing choked coils—are diagnosed and repaired on the spot within 45 to 60 minutes.
Is it worth repairing a non-cooling issue on an aircon older than 10 years?
If the fix involves minor parts like a capacitor or sensor, repair is cost-effective. However, if the main inverter compressor or outdoor PCB has failed on a 10+ year system, upgrading to a modern 5-Tick energy-efficient unit is usually a smarter long-term investment.
