The problem of noisy car AC compressors is a common issue in cars that are over five years old. This problem can certainly disrupt comfort while driving. So why does this happen? What are the causes and how can this issue be resolved? To avoid wondering, let's take a look at the following review.

Causes of Noisy Car AC Compressors

There are several factors that can cause a damaged car AC compressor to make noise. Here are the complete causes.

1. Age Factor

As time goes by, the use of the AC compressor certainly affects its performance. The older the AC compressor, the more its performance declines, which can sometimes lead to problems such as noise.

2. Poorly Installed AC Components

A noisy car AC compressor can also be caused by poorly installed AC components, such as the AC engine. Usually, improper installation causes looseness in the component, leading to vibrations and noise from the AC.

3. Friction Between AC Components

Friction between AC components can also cause the AC compressor to make noise. This usually occurs in the piston component that lacks lubrication or oil, or in a worn-out AC engine. A lack of oil in the piston will increase friction of the piston. Similarly, when the AC engine starts to wear out, its performance becomes heavier.

4. AC Line Leakage

Another cause could be a leak in the AC line. AC line leaks can cause oil and freon to deplete more quickly. This results in increased friction of the piston in other AC components, causing the cabin cooling system to produce noise.

5. Damage to the Magnetic Clutch

As is known, the magnetic clutch is an AC component that serves as a connection between the AC engine and the AC compressor. If this component is damaged, the AC system cannot operate optimally. This affects the performance of the AC compressor, causing it to fail to produce cold air and make noise.

6. Loss of Compressor Compression

A noisy AC compressor can also be caused by a loss of compression capability. Weakened compressor compression can lead to a decrease in the pumping process of freon to the condenser. This condition can cause the car's AC to fail to produce cold air and generate noise in the cabin cooling system.

7. Foreign Objects Entering the Compressor

A noisy AC compressor can also be caused by foreign objects entering the component. For example, food remnants, broken foreign objects, pebbles, dry leaves, and small items can obstruct the performance of the AC engine.

How to Fix a Noisy Car AC Compressor

To address a noisy car AC compressor, you can apply the following methods.

1. Regularly Check Compressor Oil

By checking the condition of the AC compressor oil, you can prevent compressor damage early on. As is known, AC compressor oil serves to provide lubrication to the piston part of the AC, thus reducing friction between the piston and other AC components. It is advisable to refill the compressor oil when it starts to run low. Or replace the oil if the AC compressor oil is no longer suitable.

2. Check the Piston, Thrust Bearing, and Shaft

To prevent the car AC compressor from being noisy, you need to check the piston, thrust bearing, and shaft. Ensure these components are not worn out. If they are worn, replace them immediately. For loose thrust bearings, you can tighten the component again. For the compressor shaft, ensure precision.

These are the two methods you can use to address the issue of a noisy car AC compressor. If you feel less skilled in handling this problem, just visit a Daihatsu workshop for proper handling.
