Do You Need to Press the AC Button When Using the Car Air Conditioner?
2 Answers
In summer, you need to turn on the AC for cold air, but in winter, you don't need it for warm air. Here is an introduction to how the air conditioning system works: 1. The AC button controls the air conditioning compressor. In summer, you must press the AC button to turn on the cold air. 2. Warm air, however, utilizes the car's internal heat circulation and does not require the air conditioning compressor to be activated. Therefore, to use warm air, you only need to adjust the air conditioning controls without pressing the AC button. 3. Switching between internal and external circulation is essential for long drives. The internal and external circulation functions help control the air quality inside the car and assist in maintaining temperature. 4. When controlling the air vents, drivers should follow these guidelines: point the vents upward when using cold air and downward when using warm air. 5. After the car has been exposed to the sun, avoid turning on the air conditioning immediately. It's best to open the windows first to ventilate and let the hot air escape before getting in and turning on the air conditioning.
I've been driving to and from work for over a decade and have plenty of experience with using the car's air conditioning. Whether to press the AC button depends on the situation. You must press it when cooling, as it activates the compressor to cool the air; for just ventilation or heating, there's no need to press AC. On hot summer days, I always turn on the AC to quickly cool down the car interior; in winter, I also use AC for defogging because it dehumidifies quickly and ensures safety. My car has an automatic mode—pressing the AUTO button lets the system control the AC itself, so I don’t have to worry about it. I recommend using the automatic function more often for convenience, instead of manually turning it on and off, which wastes fuel. Regularly check the AC filter to prevent odors. Using the AC correctly can enhance driving comfort, such as running it efficiently during long highway drives.
