Why Your Car AC Isn’t Cooling and How to Fix It

Anh Tuan, owner of a Hyundai Thanh Cong truck hauling construction materials in Cau Giay, Hanoi, was busy delivering to a site on Nguyen Trai Street. The scorching sun beat down as he turned on the AC, only to be met with a blast of hot air. Drenched in sweat, he felt exhausted and incredibly uncomfortable. “The AC must be broken again,” he sighed, “another hefty repair bill coming up.”

A malfunctioning car AC, especially during sweltering summer days, is a common problem for many, particularly truck drivers who spend long hours under the intense heat. So, what causes this issue and how can it be resolved? This article by XE TẢI HÀ NỘI will provide the answers.

Causes of a Car AC Not Cooling

Numerous factors can contribute to a car AC failing to cool. Here are some of the most common culprits:

1. Low Refrigerant: This is the most frequent cause. Over time, refrigerant can leak or deplete, preventing the AC from cooling properly.

2. Dirty Cabin Air Filter: The cabin air filter prevents dust, dirt, and bacteria from entering the AC system. A clogged filter restricts airflow, hindering the AC’s performance.

3. Blower Motor Malfunction: The blower motor pushes air across the evaporator coil to cool it. A faulty blower motor results in no air circulation, leading to a lack of cooling.

4. Dirty Condenser: The condenser releases heat into the environment. When it’s covered in dirt or debris, its efficiency decreases, impacting the AC’s cooling capacity.

5. Faulty Expansion Valve or Temperature Sensor: The expansion valve regulates refrigerant flow into the evaporator. The temperature sensor measures the cabin temperature and sends signals to the control module. If either component malfunctions, the AC won’t function correctly.

6. Electrical Issues: Problems with fuses, relays, wiring, and other electrical components can also prevent the AC from cooling.

7. Incorrect Refrigerant Type: Each vehicle requires a specific type of refrigerant. Using the wrong type can cause significant damage to the AC system.

• Use the correct refrigerant type specified for your vehicle.
• Turn off the AC 5 minutes before turning off the engine to prevent mold growth.

Don’ts:

• Don’t set the AC temperature too low compared to the outside temperature (maintain a 5-7 degree Celsius difference).
• Avoid running the AC continuously for extended periods, especially at low speeds.
