What Are the Most Common Aircon Repairs in Singapore?
Since AC units usually wear out over time, understanding common repairs enables you to spot problems early, execute aircon repairs, and avoid unexpected issues as a home or business owner.
Therefore, to give you a clearer picture, in this post, we will walk you through the most common AC issues and repairs.
7 Most Common Aircon Repairs in Singapore
1. Refrigerant Leaks
This is a common aircon issue. Notably, with leaks, the AC no longer cools effectively. In most cases, when your air conditioner stops cooling, this usually means there’s a refrigerant leak, as refrigerant is the essential fluid in the cooling system. Signs of a leak include hissing sounds, ice on the coils, unusual smells, warm air coming from the unit, or higher electric bills.
To fix this, a technician locates and seals the leak, then tops up the system with the correct refrigerant. Importantly, only professionals can handle refrigerants.
2. Dirty or Blocked Condensers
The outdoor condenser removes heat. Over time, dust can accumulate on condenser coils and fans, causing the unit to overheat, the compressor to cycle on and off rapidly, or the system to shut down.
Importantly, addressing this issue involves cleaning coils, realigning fins, and clearing obstructions. Notably, neglecting maintenance increases the risk of compressor failure, which usually leads to more expensive repairs or even replacement when compared to routine maintenance.
Water dripping from the indoor unit is a common AC issue. The drain line, which should channel moisture outdoors, can become clogged with mold, algae, or dust, resulting in water leaks inside.
A technician will clean the drain line and check the drain pan for cracks. Importantly, the leak should be fixed promptly, as ignoring it can lead to stains or ceiling damage.
4. Faulty Capacitors
Capacitors store and release energy to help start the compressor and fans. Notably, they wear down faster when continuously running. If there is an issue with the capacitors, the unit clicks but nothing starts, or the fan does not spin.
Therefore, you should get the dead capacitor replaced by a qualified technician to avoid electrical accidents.
5. Fan Motor or Blower Issues
The indoor blower circulates cool air. When bearings wear out, or motors overheat, which is common when ACs run around the clock, you’ll notice weak or uneven airflow and maybe odd noises.
Notably, lubrication or cleaning often solves the problem. But if not, the blower motor may need to be replaced. Replacing a blower motor is generally more expensive than routine maintenance, making this a common but costly failure with frequent use.
6. Electrical Control Problems
Older buildings can cause electrical connections to loosen or corrode. As a result, the faulty contactors and wiring may cause your AC to cut out or trip the breaker.
In such instances, the fixes include tightening wires, replacing contactors, and checking thermostats. Importantly, licensed technicians should handle electrical repairs due to the risk of fire.
7. Sensor Issues
If thermostats or sensors are dirty or misaligned, the AC may not turn on or off at the right times. This can cause the unit to run continuously or shut off prematurely.
Cleaning or repositioning the sensor can resolve the issue. Modern inverter ACs may require a software reset.
Conclusion
Ensuring regular servicing every 3-4 months prevents most AC problems and ensures prompt repairs when issues are detected and repairs are needed. Also, early detection helps you avoid costly replacements.
Lastly, always hire an NEA-licensed services company for reliable service. The regular professional servicing ensure year-round efficiency and effective AC units.
