What is the correct way to use car air conditioning in summer?

[JocelynAnn]

Summer car air conditioning usage methods are: 1. Open windows before turning on AC: After a car has been exposed to sunlight in summer, don't enter immediately or rush to turn on the air conditioning. Instead, first lower all windows or open doors, then turn on the fan to accelerate air circulation. After a few minutes, close windows and turn on AC, which helps release toxic substances; 2. While driving, drivers should avoid setting the temperature too low just for cooling comfort. Car air conditioning refers to the air conditioning device installed in vehicles that can cool, heat, ventilate and purify cabin air, providing comfortable conditions for passengers, reducing driver fatigue and improving driving safety.

In summer, my most common method of using the car air conditioning is to start the engine first, then press the AUTO button, which allows the system to automatically adjust the fan speed and cooling based on the interior temperature. I usually set the temperature knob to around 24°C to avoid catching a cold from excessively low temperatures. Before turning on the air conditioning, I open the windows for a few minutes to ventilate and expel hot air, which helps cool the car faster and saves energy. During long-distance drives, I switch between recirculation and fresh air modes: first using recirculation for rapid cooling, then switching back to fresh air after 30 minutes for better ventilation. If there are odors inside the car, I make sure to clean the AC filter regularly to prevent bacterial growth. In hot summer weather, air conditioning failure can be dangerous, so I check the cooling performance and maintenance records monthly to ensure a comfortable and safe driving experience.

I pay special attention to fuel efficiency when driving. In summer, I always open all the windows for 2 minutes before turning on the AC to let the hot air escape, then close the windows and switch to AC mode. Setting the temperature to 25°C keeps it comfortably cool while saving fuel. I make good use of the AUTO button on the automatic AC but manually reduce the fan speed to avoid excessive noise. During long drives, I briefly turn off the AC and open the windows at rest stops to ventilate, reducing fuel consumption and environmental impact. Regularly replacing the AC filter is also crucial to prevent blockages that could affect cooling efficiency. Poor AC maintenance in summer can easily lead to issues, so I check the refrigerant pressure annually to ensure eco-friendly driving.

When I first started driving, in summer I would turn on the AC by starting the engine and pressing the AC button on the center console - the illuminated light indicated cooling was activated. Then I'd rotate the temperature knob to the blue zone, usually setting it at 22°C. The fan speed dial should be adjusted to medium, as maximum setting can be noisy. If it gets stuffy after driving awhile, press the air recirculation button to switch to fresh air mode. If cooling is slow, the filter might be dirty and needs professional cleaning. Developing the habit of turning off AC before parking helps protect the battery.
