How to Use Car Air Conditioning Properly?
4 Answers
Car air conditioning should be used properly as follows: 1. Choose an appropriate temperature setting; 2. Do not immediately activate the internal circulation when entering the car in summer; 3. Avoid running the air conditioning for extended periods; 4. Do not adjust the air vent direction arbitrarily; 5. Use the air conditioning in a fully enclosed state; 6. Avoid resting or sleeping for long periods in a stationary car with the air conditioning on. The functions of car air conditioning are: 1. To adjust and control the temperature, humidity, air cleanliness, and airflow inside the cabin to an optimal state; 2. To provide a comfortable environment for passengers, reducing travel fatigue; 3. To create favorable working conditions for the driver, ensuring driving safety.
Fuel efficiency is my top priority when driving, and improper use of the air conditioning can significantly increase fuel consumption. In summer, roll down all the windows for a few minutes to dissipate heat and expel hot air from the car before turning on the AC. This avoids forcing the compressor to work continuously by immediately blasting cold air. Setting the temperature around 25°C is ideal—neither too low nor too high. Start with medium-low fan speed and avoid cranking it to maximum right away. Once the car cools down, reduce the fan speed to save fuel. Periodically switch the AC to external circulation to ventilate and prevent odor buildup. For short trips, use the fan alone without running the compressor. Developing these habits reduces engine strain, prolongs its lifespan, and is also eco-friendly.
Driving in hot weather without air conditioning is pure torture, so I need to keep the car interior comfortable. Don't rush to turn on the AC right after getting in the car—first open the windows to let the hot air escape, otherwise it feels like sitting in a sauna. Avoid setting the temperature too low as drastic temperature changes can cause colds; I usually set it between 24 to 26 degrees Celsius. Initially, set the fan speed to medium to cool down faster, then reduce it for quieter operation. Occasionally switch between recirculation and fresh air modes to let in fresh air and prevent dizziness. A few minutes before parking, turn off the AC compressor and keep only the fan running to avoid sudden overheating when exiting the car. On rainy days, use the defrost function to dehumidify and maintain clear visibility. Remembering these small details makes the entire drive much more comfortable.
After driving for a long time, I've accumulated some experience in air conditioning maintenance. Proper usage can extend its lifespan and prevent frequent issues. Before turning it on, check that the vents are unobstructed, and avoid setting the fan speed to the highest immediately to prevent motor burnout. Setting the temperature moderately is sufficient; extreme highs or lows can damage the compressor. Turn off the air conditioning system a few minutes before shutting down the car to allow the fan to dry the interior and prevent mold. Regularly clean or replace the air filter, and address dust buildup promptly to avoid bacterial growth. In summer, avoid prolonged high-load operation, and open windows when parked to ventilate and cool down. Routine simple checks can save on repair costs and hassle.
