Knowing the signs of a damaged car AC compressor is absolutely necessary. Understanding this helps you comprehend why a car AC compressor can experience damage. If you are not aware of this, do not worry.

We will inform you about it through this article. Don't believe it? Please directly check the discussion below!

Rough Sounds

The first sign of a damaged car AC compressor is the emergence of rough sounds. Like the sound of two objects rubbing against each other, or the sound of someone snoring.

This sign will appear when you change the AC button to positions 1-2-3. If you switch the button to the OFF position, you will no longer hear that sound. This sign of a damaged car AC compressor is mainly caused by the depletion of oil in the car AC compressor.

AC Compressor Starting to Leak

The second sign of a damaged car AC compressor is a leak from the compressor itself. This sign appears when the AC air starts to be less cold than usual, along with a decrease in freon in the AC compressor.

If left unchecked, the freon in the AC will continue to decrease, or even run out. This second sign usually lasts quite a long time. Approximately one to six weeks.

Compressor Output Starting to Decrease

You will feel this third sign when driving the car at both low and high speeds. The indication of this third sign is the low airflow from the AC when the car is moving at low speed. However, when the car is moving at a higher speed, the airflow from the AC increases and feels very cold.

Magnetic Clutch

The last sign of a damaged car AC compressor can be felt when the car is in heavy traffic. One indication of the magnetic clutch is that the car cabin starts to feel warm, even though you have turned on the AC inside.

The cold air from the AC will turn back on when the AC is turned off for a moment. Or, when the car has accelerated above 1,000 rpm.

What Should Be Done?

When you find the signs above, do not get too caught up in panic. As much as possible, take your car to the nearest workshop immediately. It is safer if the workshop you go to is an official workshop.

Make sure you bring enough funds when doing this. Usually, the cost of repairing a car AC compressor is around Rp 2 million - Rp 3 million. And if you have to replace it, you should have around Rp 5 million.

Maintaining Your Car AC Compressor

To avoid damage, you should start regularly maintaining your car AC compressor. It is not difficult to do this. You just need to follow the steps below!

Do Not Turn On the AC When the Cabin Feels Too Hot

When the cabin feels too hot (especially due to excessive sunlight), we recommend not turning on the car AC. This will not automatically cool your car cabin.

If you want, open the car windows first until the hot air in the cabin is completely released. Only then can you turn on the car AC to cool the cabin.

Regularly Clean the Car Cabin

The car cabin greatly affects the performance of the car AC. The cleaner the cabin, the easier it is for the car AC to produce cold air. Therefore, you should start regularly cleaning your car.

In addition to the two steps above, there are still other steps that can be taken, namely:

  1. Regularly clean the AC filter.
  2. Regularly warm up the AC in the car.
  3. Always turn the AC on and off when the car is at low speed.
