What is the AC button in a car used for?

AC button is the cooling switch of the air conditioner. After pressing the AC button, the air conditioner will start cooling. The function of AC: The AC button in a car is the cooling switch of the onboard air conditioner. When the weather is hot and you need to turn on the air conditioner to cool down, press the AC button (an indicator light should illuminate on the button), and the car's air conditioning compressor will start working. Cold air will blow out from the vents, lowering the temperature inside the car. This provides a comfortable riding environment for passengers and reduces travel fatigue. How to use AC: When cooling is needed, press the AC button while adjusting the temperature selection switch to the blue section and turning on the fan switch. Only then will cold air blow out.
The other day while driving on the highway, I noticed the AC wasn't cooling properly, so I specifically went to consult a mechanic. The AC button is essentially the switch for the air conditioning compressor - you need to press it for the AC to provide cooling. In summer, you must turn on the AC button when using the air conditioning, otherwise it will just blow natural air or warm air from engine heat. I've developed the habit of opening the windows for about two minutes to let the heat out before turning on the AC - this makes the cooling more effective. During long drives, it's best not to set the AC fan speed too high; keeping the temperature around 25°C is most comfortable. Remember you don't need to use the AC button in winter - just use the heater directly. Regular cleaning of the AC filter is also very important, otherwise it can easily develop unpleasant odors.
