What are the reasons for the car air conditioner not being very cold?

Reasons for the car air conditioner not being very cold include: 1. Dirty condenser; 2. Dirty air filter; 3. The air conditioner is in long-term external circulation mode; 4. Aging belt. Solutions: 1. Check if there is refrigerant in the system. If not, pressurize to check for leaks and refill as needed; 2. If there is refrigerant, check if the compressor is working; 3. Clean the condenser; 4. Replace the air filter. The car air conditioner is a device that cools, heats, ventilates, and purifies the air inside the vehicle, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety.
Over the years, I've encountered many cases of car AC not cooling properly. The most common issue is insufficient refrigerant, commonly referred to as low freon, often accompanied by leaks in the piping that need inspection. Blocked condensers are another problem, especially during spring when willow catkins clog the radiator fins, affecting cooling efficiency. Slipping compressor belts or clutch failures can also cause insufficient cooling, resulting in intermittent AC performance. Electrical system issues shouldn't be overlooked either - blown AC fuses or control panel failures can cause complete system shutdown. For daily maintenance, I recommend regularly cleaning AC air intakes and replacing filters. Before long-term parking, remember to turn off the AC first and let the blower dry the evaporator to prevent mold and odors.
