How to Maintain a Car Air Conditioner in General?
2 Answers
Car air conditioner maintenance methods: 1. Regularly check the refrigerant and compressor oil; 2. Clean the surface of the condenser; 3. Clean the surface of the evaporator. The car air conditioning system, referred to as car AC, consists of a refrigeration system, heating system, ventilation and air purification devices, and a control system. The functions of the car air conditioner are: 1. To adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to a better state, providing a comfortable riding environment for passengers and reducing travel fatigue; 2. To create good working conditions for the driver, serving as an important ventilation device that ensures safe driving.
Having driven for years, AC maintenance is just a daily habit that needs to be cultivated. Every time I get in the car, I don’t rush to turn on the cold air—I let the fan run for a few seconds first to warm up the system, even in winter. This helps prevent bacterial buildup. The most crucial thing is replacing the cabin air filter—I usually do it every six months. Buying a cheap one online works fine, and it only takes about 10 minutes to swap it out. After changing it, the air feels much fresher without that dusty smell. Also, before parking, I turn off the AC but let the fan run a bit longer to dry the evaporator surface, preventing mold. In summer when it’s used more often, don’t forget to check the refrigerant—if cooling feels slow, top it up at a shop. Regularly clean the vents with a soft cloth to keep dust from clogging the airflow. In short, keeping it simple can save a lot on repair costs.
