Should the A/C be turned on in the car during summer?

During summer, the A/C in the car must be turned on; otherwise, the air blown out will not be cold. Here are some additional tips: 1. To quickly lower the temperature inside the car during summer, you can adjust the position of the air vents. 2. According to the principle of air convection, hot air rises while cold air sinks. You should aim the air vents slightly upward to utilize this principle—as the cold air descends, it rapidly cools the interior of the car. Also, avoid placing decorations in front of the air vents, as this can affect the cooling efficiency. 3. Additionally, if the car has been parked outdoors under prolonged exposure to the sun, the correct approach is to first start the engine for preheating. Once the engine temperature gauge reaches the midpoint, turn on the A/C and set the air circulation to external mode to expel the hot air from the car. After 2~3 minutes, switch the air circulation to internal mode.
Having driven for many years, I know that during scorching summer days, the car's air conditioning simply won't work without turning on the A/C button, as it's the core control for the compressor's cooling function. Only when activated can it truly blow cool air to lower the temperature. Many mistakenly believe that just running the fan is enough to stay cool, only to find the car becoming increasingly stuffy and hot, impairing visibility and judgment—which is quite dangerous. The A/C isn't just for cooling; it also dehumidifies and prevents dampness, benefiting both the elderly and children. It's advisable to open the windows to release hot air before starting the car, then activate the A/C and set the temperature around 24°C. The air conditioning system requires regular maintenance, and avoiding long-term disuse of the A/C can prevent compressor rust, saving on costly repairs later. Functionally speaking, using the A/C is a fundamental necessity for summer driving.
