AC Mobil Dingin Sebelah? Ini Penyebab dan Cara Mengatasinya!

A car's air conditioning being cold on one side is a problem that should not be taken lightly. This issue greatly disrupts driving comfort, especially during traffic jams and hot weather. So what causes this problem to occur? And how can it be resolved? For more details, please refer to the review below.

Causes of One-Sided Cold Car AC 

There are several factors that cause a car's AC to be cold on one side that you need to know. Here are the complete causes.

1. Clogged air filter

A car's AC being cold on one side can be caused by a clogged air filter. The dirt that accumulates inside the air filter can obstruct the airflow in the car's AC system. This causes the cold air supplied by the AC to be uneven as it only comes out from one side.

2. Freon leak

The next cause of a car's AC being cold on one side is due to a freon leak. As is known, freon functions to maintain the refrigerant pressure in the car's AC. If the freon leaks, the pressure decreases, causing the car's AC to only supply cold air on one side.

3. Problematic air fan or blower

A problematic air fan or blower can also cause a car's AC to be cold on one side. This component functions to distribute cold air evenly in the AC system. If this component has issues, its function cannot be optimal. 

4. Problematic air ducts

A car's AC being cold on one side can be caused by problematic air ducts. This component functions to channel cold air into the car's cabin. If this component is clogged or leaking, the temperature inside the car's cabin will experience a significant difference.

5. Problematic AC electronic components

AC electronic components such as cooling actuators or temperature sensors that are problematic can also cause a car's AC to be cold on one side. As is known, these components function to distribute cold air evenly inside the car. If these components have issues, it is certain that the car's AC will only emit cold air from one side. 

How to Fix One-Sided Cold Car AC 

To address the problems above, you need to use the following methods.

1. Regularly check and clean the air filter

To prevent the car's AC from being cold on one side, you need to regularly check the condition of the filter. If the air filter looks dirty, clean it immediately to avoid clogging.

2. Regularly check the freon level

Regularly checking the freon can anticipate any freon leaks, thus avoiding problems like one-sided cold AC. If the freon has already leaked, immediately perform repairs and recharge the refrigerant.

3. Regularly check the air fan or blower

Regularly checking the air fan or AC blower can prevent damage to these components. If damaged, replace them immediately with quality components.

4. Regularly check the air ducts

Regularly checking the air ducts can also prevent the car's AC from being cold on one side. If there is damage, visit a car AC specialist workshop for replacement.

5. Regularly check the electronic components in the AC system

Regularly checking the electronic components in the AC system can also prevent the car's AC from being cold on one side. Replace components immediately if any damage occurs.
