Why Is My Aircon Making Noise in Singapore: An Easy Guide

If you live in Singapore and feel like your aircon making noise, you should never ignore it because it can disturb your comfort sooner. Living in Singapore, aircon is a necessity rather than a luxury because of the constant heat and humidity. However, when your aircon makes unusual noises, it can indicate an issue. Homeowners need to be aware of the issues that can cause the aircon to make noises. 

Why is My Aircon Making Noise in Singapore?

There can be several reasons for an AC making noise, but you need to know the most common causes and the possible remedies for each. LS Aircon Servicing Singapore explains the reasons and possible solutions for an air conditioner making noise. If you want to avail professional services, they also offer aircon repair, general services, and gas top-up services. 

Loose or Displaced Parts

One of the most frequent causes of noise in an aircon is loose parts. Over time, components can become loose due to the constant vibrations of the unit. This can result in banging sounds when the aircon operates. 

If you ignore these sounds, these loose parts can cause more severe damage to the unit. Regular maintenance and inspection can help identify and tighten these components before they cause further issues.

Clogged Air Filters

Air filters are crucial to your aircon’s performance. They also ensure good air quality and efficient operation. However, when these filters clog, they can restrict airflow. The restricted airflow forces the aircon to work harder. This can produce unusual noises such as humming or buzzing. Ensure regular cleaning and timely replacement of air filters to prevent this issue.

Faulty Fan Blades

The fan inside your aircon circulates cool air throughout the room. If the fan blades have an issue, they can collide with other components inside the unit and cause loud noises. In some cases, the fan motor starts malfunctioning and causes unusual noises. 

If you feel the fan is the issue, it’s wise to hire a professional for professional inspection and possible repair and replacement. This will save you from huge replacement costs later on. 

Refrigerant Issues

The refrigerant in your aircon is essential for cooling the air. If there’s a leak or the refrigerant levels are too low, your aircon may produce hissing or bubbling sounds. These noises indicate a severe problem and require a prompt response from the homeowners. Low refrigerant levels can reduce the cooling efficiency of your aircon and result in compressor damage, which is costly to repair. 

Compressor Problems

The compressor is the heart of your cooling system. Therefore, any issues with the compressor can lead to loud and disturbing noises. A malfunctioning compressor might produce a loud knocking sound, and you should never ignore this issue. 

Because of the importance of the compressor in the cooling system, you should never prolong the issue and immediately hire a professional to inspect and take corrective measures. 

Debris in the Outdoor Unit

Singapore’s tropical climate means your aircon’s outdoor unit is often exposed to debris. These materials can get trapped inside the unit and cause the fan or other moving parts to grind or rattle. 

Regular maintenance and cleaning of the outdoor unit are essential to prevent debris from causing such issues. Moreover, cleaning and maintenance ensure a smooth running aircon system throughout the year.

Electrical Issues

If you feel your aircon making noises, it may be due to the electrical issues within the aircon unit. Electrical problems within the air conditioner, such as a malfunctioning capacitor or relay switch, can cause buzzing or clicking noises. 

These issues are hard to diagnose and rectify without professional assistance. Electrical issues can also cause safety hazards; therefore, it is crucial to hire a professional to rectify the issues promptly. This can prevent further damage to the aircon and the whole electrical circuit. 

Conclusion

In conclusion, if you notice an aircon making noise, it indicates underlying technical issues. Understanding the root cause and giving timely response can save you from costly maintenance down the line. If you prolong or ignore this issue, it will escalate further and cause several problems for your cooling system. Therefore, if you notice your aircon is making unusual noises, you should be quick to respond to this issue.
