If your air conditioner is noisy, you're not alone. Many homeowners in Malaysia face this issue, especially when the weather gets hotter during the dry season. Understanding the reasons behind the noise can help you address the problem effectively and ensure your air conditioner runs smoothly and quietly.

Common Causes of Noisy Air Conditioners

Debris and Dirt Accumulated dirt, leaves, and other debris can obstruct the fan or other moving parts, leading to a noisy operation.
Refrigerant Leaks A hissing or bubbling noise can indicate a refrigerant leak. This not only makes your air conditioner noisy but also reduces its efficiency.
Compressor Problems The compressor is the heart of your air conditioner. If it's faulty, it can cause significant noise, indicating a need for professional repair.
Loose Parts Over time, the components of your air conditioner can become loose due to regular usage. Screws, bolts, and other parts might rattle, causing noise.
Fan Issues The fan blades or the motor can be another source of noise. If the blades are damaged or the motor bearings are worn out, they can produce a loud sound.
