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

“The engine purrs, the car glides smoothly down the busy Truong Chinh Street, yet inside, it feels like a furnace.” Many drivers have likely experienced this frustrating situation when their car’s AC suddenly malfunctions. So, what causes a car AC to stop cooling, and how can you effectively fix it? Let’s diagnose the “lungs” of your beloved vehicle with Hanoi Trucks!

Causes of Car AC Problems and Solutions

1. Low Refrigerant Levels

This is the most common reason for poor AC performance. Insufficient refrigerant reduces the system’s cooling capacity.

Signs:

• Weak airflow, not cold enough.
• Frost buildup on the evaporator coil.

Solution:

• Take your car to a reputable garage for inspection and refrigerant recharge.
• Choose high-quality refrigerant suitable for your car model.

Expert Advice:

According to Mr. Nguyen Van A, a technician at Thanh Cong Auto Repair in Cau Giay District, Hanoi: “Refrigerant should be recharged regularly, about every 6 months or as recommended by the manufacturer. Using low-quality refrigerant or improper recharging can damage the AC system.”

2. Dirty Cabin Air Filter

A clogged air filter restricts airflow through the evaporator, reducing cooling efficiency.

Signs:

• Unpleasant odors from the AC.
• Weak airflow even at high fan speed.

Solution:

• Replace the cabin air filter regularly, every 6,000 miles or 6 months.
• Choose genuine filters or equivalent quality products.

Note:

Cleaning the cabin air filter is only a temporary solution and cannot replace a full replacement.

3. Dirty Condenser Coil

The condenser releases heat from the AC system. When it’s dirty, heat dissipation is reduced, directly impacting cooling performance.

Signs:

• Poor AC performance, especially at low speeds.
• High refrigerant pressure, potentially damaging the system.

Solution:

• Clean the condenser coil regularly, every 6 months.
• Use a high-pressure washer or take your car to a garage for professional cleaning.

4. Malfunctioning Condenser Fan

The condenser fan cools the condenser. If it malfunctions, the condenser overheats, affecting the entire AC system.

Signs:

• Poor AC performance, especially when idling.
• Unusual noises from the condenser area.

Solution:

• Inspect and repair or replace the condenser fan.

5. Other Component Failures

Besides the common causes above, a malfunctioning AC can also result from issues with components like the expansion valve, temperature sensor, or compressor.

Solution:

• Take your car to a reputable garage for diagnosis and timely repairs.
