Aircon Repair Singapore

Vetted technicians from licensed contractors diagnose the fault first ($46.00 visit). Same-day slots available.

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.

Common Reasons Your Aircon Needs Repair

Lack of Maintenance: Without regular cleaning and servicing, dirt and dust build up inside the unit, affecting performance and causing system failures.
Wear and Tear: Components like compressors, motors, and fans naturally degrade over time due to continuous operation.
Electrical Issues: Problems like blown fuses, faulty wiring, or tripped breakers can prevent the system from operating properly.
Refrigerant Leaks: Low refrigerant levels reduce cooling performance. Leaks often occur in the piping, evaporator coil, or condenser unit.
Old Age: As systems age, they become less efficient and more prone to breakdowns—especially if they're not maintained regularly.

Signs Your Aircon Needs Repair

Watch out for these common signs that indicate it's time to book an aircon repair service:

Poor Airflow

Weak airflow may be due to clogged filters or a failing motor.

Noisy Operation

Rattling, squeaking, or grinding sounds often signal loose parts or motor issues.

Foul Smells

A musty or moldy odor may be caused by a dirty filter or mold buildup inside the unit.

Water Leakage

Leaks can occur from clogged drainpipes, a cracked condenser, or refrigerant issues.

Not Cooling Properly

If warm air is blowing, it could be a refrigerant leak or a broken compressor.

High Electricity Bills

Unusually high bills may indicate your unit is overworking due to inefficiency or faults.

Frequent Shut-Offs or Won’t Turn On

Could be caused by overheating, dirty coils, or electrical problems.

Blinking Indicator Lights

Often signals internal faults like motor issues or sensor malfunctions—refer to your unit’s manual.

Common Problems We Fix

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.

💧Leaking

Leaking Water

Water leakage is usually caused by a clogged drain line or dirty filters. It can lead to dripping from the FCU unit.

🌡️Cooling

Cooling Problem

Aircon not blowing cold air? It may be due to low refrigerant gas, dirty coils, or a faulty condenser unit.

Fix A/C Cooling

🔥Overheating

Overheating

Overheating is often due to dirty filters, clogged coils, or long operation hours without servicing.

⚙️Compressor

Compressor Repair

Compressor not starting, cutting out or noisy? It is often a capacitor, overheating or low gas, which costs far less than the compressor.

🔌PCB

PCB Replacement

The PCB controls the FCU and compressor functions. A damaged PCB can stop your system from powering or responding.

🔊Noisy

Noisy Aircon

Strange sounds from the A/C units may come from the blower, compressor, or motor. It often means worn-out parts.

DIY Troubleshooting: Aircon Won’t Turn On

Follow these steps to identify why your air conditioner isn’t powering up:

Power Supply: Ensure the unit is plugged in and the outlet is functional. Try another outlet if unsure.
Remote or Thermostat: Check if the remote has power. Replace batteries if the display is blank.
Circuit Breaker: Look for tripped breakers in your electrical panel and reset them if needed.
Internal Components: If basic checks don’t resolve the issue, there may be a problem with the compressor, capacitor, or motor. Contact a professional for repairs.
