Do you need to turn on AC when using car air conditioning for cooling?

When using the car's air conditioning for cooling, it is necessary to press the AC button. Here is the relevant information: 1. The car air conditioning device (air-conditioning-device), referred to as car air conditioning, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state. It provides a comfortable riding environment for passengers, reduces travel fatigue, and creates good working conditions for the driver, playing an important role in ensuring safe driving. 2. It generally includes refrigeration devices, heating devices, and ventilation devices. This combined device makes full use of the limited space inside the car, has a simple structure, and is easy to operate, making it a popular modern car air conditioning system internationally. The arrangement of different types of air conditioning systems varies. Currently, integrated heating and cooling air conditioning systems are widely used in cars.
With my extensive driving experience, I find the AC button crucial when using the car's air conditioning. The AC system is essentially the cooling function of the air conditioner. Pressing it activates the compressor, allowing the refrigerant to flow and produce cold air. Without turning on the AC, even if the temperature dial is set to the coldest and the fan is on high, it will only blow out room-temperature air, especially during hot summers when it just won’t cool down. The compressor relies on the engine's power, so using the AC slightly increases fuel consumption, but it’s worth it for comfort. I’ve tried it myself—without the AC and just the fan, the car remains stuffy and uncomfortable. But once the AC is on, the air instantly feels cool. Just locate the button labeled "AC" or with a snowflake symbol in your car and press it—simple and effective. Regular maintenance of the AC system is also key to avoid leaks and ensure proper cooling.
