Why is Your Aircond Compressor Making Noisy and How to Fix It?

Table of Contents

In Malaysia’s hot, humid climate, comfort depends on a functioning air conditioner. A frequent problem is the aircond compressor making noisy sounds, which can signal deeper issues. This article discusses why this happens and how to fix it, providing insights and solutions to keep your air conditioning unit running quietly, ensuring a peaceful and comfortable environment.

Understanding Your Aircond Compressor

The aircond compressor is often referred to as the heart of the air conditioning system. It plays a crucial role in the refrigeration cycle by compressing the refrigerant and circulating it through the system. This process is vital for removing heat from your indoor environment and releasing it outside, thus cooling your space.

Common Causes of Noisy Aircond Compressors

  • Age and Wear: Over time, the internal components of a compressor can wear out, leading to increased noise levels. This is a natural process as the unit ages.


  • Loose Parts: The compressor and other parts of the aircond unit can become loose due to constant vibrations during operation. This can result in rattling or banging noises.


  • Refrigerant Issues: Incorrect refrigerant levels, either too high or too low, can cause the compressor to work harder than normal, leading to unusual noises. 


  • Dirty Coils: When the coils in the aircond unit are clogged with dirt and debris, they can put extra strain on the compressor, causing it to become noisy.


  • Electrical Issues: Problems with the electrical components, such as faulty capacitors or damaged wiring, can also lead to abnormal sounds from the compressor.

Diagnosing the Noise

Identifying the type of noise your compressor is making can be key to diagnosing the problem. A buzzing noise might indicate an electrical issue, while a rattling sound could suggest loose components. Regular maintenance checks, as highlighted in this detailed study, can help catch these issues early before they develop into more significant problems.

DIY Fixes vs Professional Help

  • Simple DIY Fixes: Tightening loose screws and cleaning the external parts of the unit can sometimes resolve minor noise issues.


  • When to Call a Professional: If the noise persists or you suspect issues such as refrigerant problems or electrical faults, it’s time to call in the experts. Handling these issues requires professional knowledge and tools. Our team of experts at SIFU Engineering’s repair services is always ready to assist you.
