Singapore's hot and humid tropical climate—with temperatures averaging 26°C to 34°C and humidity levels reaching 100%—makes air conditioning a daily necessity for most residents.
Due to this constant use, it's common for air conditioning systems to develop faults over time. Below, we explore the common reasons why your aircon may need repair in Singapore.
Watch out for these common signs that indicate it's time to book an aircon repair service:
Weak airflow may be due to clogged filters or a failing motor.
Rattling, squeaking, or grinding sounds often signal loose parts or motor issues.
A musty or moldy odor may be caused by a dirty filter or mold buildup inside the unit.
Leaks can occur from clogged drainpipes, a cracked condenser, or refrigerant issues.
If warm air is blowing, it could be a refrigerant leak or a broken compressor.
Unusually high bills may indicate your unit is overworking due to inefficiency or faults.
Could be caused by overheating, dirty coils, or electrical problems.
Often signals internal faults like motor issues or sensor malfunctions—refer to your unit’s manual.
Most common problems you might face with your air conditioner like not enough cooling, leaking water, malfunctioning PCB, choked drainage pipe, noisy condenser or overheating FCU.
Before starting any repairs, a technician will conduct a thorough assessment to identify the root cause of the issue. Once diagnosed, you will receive a quotation for the repair. In some cases, replacing your aircon may be more cost-effective than repairing it.
Often, common issues can be resolved immediately with deep cleaning and minor parts replacement.
Once the unit is repaired, be sure to test its cooling, oscillation, and remote control functions before the technicians leave.
