How to Turn on the Car Air Conditioning in Summer?
3 Answers
When using the car air conditioning in summer, you can first turn on the external circulation or open the windows for ventilation, then switch to internal circulation. Here is some relevant information: 1. Appropriate Temperature: Choosing the right air conditioning temperature is the first step in maintaining the system. Due to the hot weather, many car owners prefer setting the temperature too low, which can affect health. Normally, the temperature inside the car should be 5°C to 6°C lower than the outside temperature, meaning the optimal air conditioning temperature is between 18°C and 25°C. 2. Adjusting the Air Vent Direction: Remember the principle that cold air sinks and hot air rises. The rule for car air conditioning vents is: point them upward when cooling and downward when heating.
Don't rush to turn on the AC when you first get in the sweltering car! I always start the engine and let the RPM stabilize first, then open all windows and the sunroof to vent the hot air. Wait about three minutes before pressing the AUTO button on the center console - the AC will start working automatically. Setting the temperature dial to around 24°C is most comfortable, as the fan speed adjusts itself. If the sun is particularly intense, I turn on recirculation mode for faster cooling, but switch to fresh air mode after half an hour to ventilate, otherwise the cabin gets stuffy. Remember to have mechanics check the cabin air filter during each maintenance - last time mine was clogged and the vents blew out dusty air. Turn off the A/C five minutes before parking while keeping the fan on to prevent mold in the ducts.
As a mom, the biggest fear is the child getting heatstroke. There are tips for using the car AC when taking kids out in summer. Don't close the windows immediately after getting in the car—hold the unlock button on the key for five seconds to open all four windows for ventilation. Wait two minutes after the engine starts before turning on the AC, and set the temperature around 25°C for optimal comfort. Avoid directing the vents straight at the child's car seat. I manually adjust the fan speed to medium, as high speed is too noisy and disturbs the child's sleep. Remember to activate the rear-seat independent vent button, or the front will freeze while the back still sweats. On long highway drives, always switch to external air circulation to prevent drowsiness from high CO₂ levels. I check the cabin air filter under the glovebox monthly—once found it clogged with willow catkins, which explained why my child kept sneezing.
