The heat of the sun will not be felt if you are inside a car with the AC turned on. But what if your car's AC is broken or not functioning as usual?

The temperature that should be cold instead turns hot. Or it even produces harsh sounds that disturb the ears. The damage to the car's AC is usually caused by a malfunctioning AC compressor. The AC compressor can also be referred to as the heart of the entire AC system. The compressor is one of the key components. Without the compressor, the entire AC system will not work.

The task of the compressor is to compress the gas freon throughout the system so that the compressor can expel heat and humidity from the air inside the cabin. When a malfunction occurs in the compressor, it is generally caused by hidden problems that are not easily visible, causing the system to be under too much pressure. The way to repair a damaged AC compressor depends on the type of damage and which component is broken. Therefore, to fix it, you need to first identify the problem occurring in the AC compressor.

Rusty Car AC Compressor

Generally, a stuck compressor is caused by the appearance of rust on the compressor's shaft with a bamboo bearing. The good news is that if the cause of your car's AC damage is due to a stuck compressor, you do not need to replace it with a new one. The rust can be removed, and the method to remove it is easy. First, disassemble the compressor and clean it with anti-rust. Second, sand it until smooth. Third, replace the compressor oil with new oil. However, you must also ensure that there are no defects in the compressor, such as a piston, cylinder wall, or broken valve. If the valve is broken, of course, you have to replace the compressor with a new one.

Noisy Compressor

If the AC compressor is noisy, you should first pay attention to the compressor oil. The compressor oil serves as a lubricant to reduce friction and prevent the compressor from overheating quickly. There may be an error during the oil filling process or a leak in the compressor.

Next, also check if the piston has worn out. This can happen in cars that are over five years old or cars that have minimal AC system maintenance. A worn piston is one of the causes of the AC producing harsh sounds that are disturbing. If this happens, you need to replace the compressor with a new one.

In addition, also check the thrust bearing. If the thrust bearing is loose, the noisy sound can be resolved by tightening the loose thrust bearing. Also check the AC. For Denso-type AC, an imprecise AS on the compressor can cause the piston movement to exceed the maximum limit. If this happens, there will be a collision on the compressor valve, producing noise when the AC is activated.

Stuck AC Compressor

A stuck AC compressor is usually due to the compressor being forced to work when experiencing thermal issues without any repairs. As a result, the compressor becomes stuck and may even burn out. If your car's AC compressor has burned out, you will certainly need to replace it with a new one. Proper and regular maintenance of the AC compressor is essential to keep the cold air in the cabin consistent. It is very important to perform routine maintenance on the AC system at least twice a year.

Not only the car engine needs regular maintenance, but the parts you use most often should not be overlooked, such as the AC system. Without it, you will feel hot, my friend.
