Car AC Intermittent Cooling: Causes and Solutions

“Driving a truck long distances with the AC blowing hot and cold is like playing a game of chance! Just the other day, hauling cargo from Ha Dong to Son Tay, the sun was scorching, and the AC started acting up again. The heat was unbearable, and I almost got heatstroke,” shared Mr. Tuan, a long-time truck driver in Hanoi.

The issue of “car AC intermittent cooling” is all too familiar to drivers, especially during the sweltering summer months. So, what causes this problem, and how can it be fixed? Let’s explore this with XE TẢI HÀ NỘI in the article below.

1. Causes of Intermittent Car AC Cooling

Many factors can lead to inconsistent AC performance in trucks. The most common include:

• Low Refrigerant: This is the most frequent cause. When the refrigerant level in the AC system is insufficient, the system will operate weakly and cannot cool effectively.
• Clogged AC System: Due to accumulated dirt and debris or the use of low-quality refrigerant, the AC system can become blocked, preventing refrigerant circulation.
• Dirty Cabin Air Filter: A dirty cabin air filter obstructs airflow, hindering the cold air from escaping and resulting in weak cooling.
• Faulty Expansion Valve: The expansion valve regulates the flow of refrigerant into the evaporator. If the valve malfunctions, the refrigerant supply becomes uneven, leading to intermittent cooling.
• Malfunctioning Condenser Fan: The condenser fan cools the condenser, allowing the refrigerant to condense. When the fan fails, the condenser cannot cool properly, reducing cooling efficiency.
• Faulty Temperature Sensor: The temperature sensor measures the cabin temperature and sends signals to the control unit to adjust the AC operation. A faulty sensor prevents accurate AC operation, resulting in inconsistent cooling.
• Faulty AC Compressor: This is the most crucial component of the AC system, responsible for compressing the refrigerant. If the compressor fails, the AC system will not function.

3. Tips for Using Car AC

To ensure efficient and long-lasting performance of your truck’s AC system, consider the following:

• Regular AC Inspection and Maintenance: Have your AC system serviced every 6 months or every 10,000 km.
• Use Quality Refrigerant: Use the refrigerant recommended by your vehicle’s manufacturer. Avoid using low-quality refrigerants, which can clog the system.
• No Smoking in the Vehicle: Cigarette smoke can stick to the cabin air filter and evaporator, causing unpleasant odors and affecting cooling performance.
• Avoid Setting the AC Temperature Too Low: Maintain a temperature difference of 5-7 degrees Celsius compared to the outside temperature.
