What are the common reasons for a car's air conditioning not cooling properly?

The reasons for a car's air conditioning not cooling properly are: 1. Refrigerant leakage: This may occur due to accidents or disassembly of air conditioning pipes and other components, affecting the sealing and leading to insufficient refrigerant. First, check if there is any leakage in the pipes; 2. Condenser cooling failure: The condenser is usually located at the front of the engine compartment. While driving, factors like wind resistance may cause condenser failure, reducing cooling performance and affecting air conditioning efficiency; 3. Blocked ventilation ducts or dirty air conditioning pipes: The air filter's role is to prevent external dust from entering the car. After prolonged use, it may become clogged, affecting the air conditioning's airflow. Even when the air conditioning is set to the highest setting, the cooling effect remains poor, and there may be noticeable noise.
It's really frustrating when the car AC isn't cold in summer. There are several common reasons: insufficient refrigerant, usually caused by aging seals leading to leaks, which is quite common in older vehicles. The compressor is the core component - if it's broken or has bearing wear, the AC won't cool at all, and you might hear strange noises. A dirty condenser surface affects heat dissipation, especially with urban driving where there's more dust. If the fan isn't working properly for cooling, the air vent temperature will be higher. Electrical issues like blown fuses or relay failures can interrupt the current. A clogged cabin air filter also reduces airflow, making the cooling feel less noticeable. It's recommended to have the system pressure checked and refrigerant topped up at a professional shop, as regular maintenance can extend the AC's lifespan. In summary, most of these issues result from accumulated minor problems - getting them fixed early ensures both safety and peace of mind.
