Understanding Why Your Aircon Is Noisy and How to Fix It

Here in Singapore, air conditioners are more than a luxury; often, they are necessary to combat the year-round heat. With such frequent usage, aircon issues can and should be expected. One of the telltale signs is when your aircon unit is no longer the silent operator it once was. If you are wondering why your aircon is noisy, it could very well be down to one of several common aircon issues. Let’s take a closer look at what these issues may be and how you can fix them.

One of the most common reasons why your aircon is noisy is clogged air filters. These filters are designed to trap dust, dirt, and debris, ensuring clean air circulation. However, over time, they can become clogged, reducing airflow. This forces the unit to work harder, producing a noticeable increase in noise levels.

Solution: Regular aircon servicing and maintenance is absolutely critical here. Clean or replace your air filters every one to three months, depending on usage. This not only helps reduce aircon noise but also improves energy efficiency and air quality.

Fan blades play a crucial role in circulating air within the unit. If they become damaged, unbalanced, or clogged with debris, they can create rattling or buzzing noises during operation. This type of air conditioner noise is both irritating and indicative of a problem.

Solution: Inspect the fan blades for any visible signs of damage or debris. Clean them thoroughly and, if necessary, replace them. Properly balanced and clean fan blades will go a long way in keeping your aircon unit running smoothly and quietly.

Another reason why your aircon is noisy could be down to its internal parts vibrating or knocking against each other. Over time, components within your aircon unit can become loose or damaged due to regular wear and tear, causing said parts to destabilise.

Solution: Check for any loose screws or parts and tighten them. If any components are damaged, consider engaging in professional aircon repair services to replace them. Addressing these issues promptly can significantly reduce aircon noise.

Refrigerant is essential for your air conditioner’s cooling process. If you are wondering why your aircon is noisy, identifying the air conditioner noise itself could clue you in on what kind of issue it is facing. If you hear hissing or bubbling, it could be due to low refrigerant levels or even a leak. These issues not only affect the unit’s performance but can also lead to costly repairs if left unresolved.

Solution: Low refrigerant levels or leaks should be handled by a qualified technician. Seek professional aircon servicing as soon as possible so the technician can inspect the system, repair leaks, and recharge the refrigerant to ensure optimal performance and quiet operation.

The compressor is a vital component of any air conditioning system. If it becomes worn or malfunctions, it can produce loud noises such as grinding, clanking, or banging. These noises are often a sign of serious internal issues that require immediate attention.

Solution: Compressor problems typically require professional intervention. Depending on the severity of the issue, the compressor may need to be repaired or replaced. Investing in professional aircon servicing can help you avoid unexpected breakdowns and prolong the lifespan of your unit.

To avoid noisy aircon problems in the future, consider the following preventative steps:

• Schedule regular aircon servicing to keep your unit in optimal condition.
• Invest in a comprehensive aircon servicing package for routine maintenance and early detection of potential issues.
• Replace older units with newer, quieter models if repairs are no longer cost-effective. Aircon replacement services can provide you with a newer and more efficient unit.
