Can I Turn on the Air Conditioner Immediately After Starting the Car?
2 Answers
It is not recommended to turn on the air conditioner immediately after starting the car. It is better to drive for a while before activating the air conditioner. Below is a detailed introduction to the specific buttons of the car air conditioning system: 1. Cooling Switch: Most car air conditioners use the "A/C" symbol. The "Airflow Direction Adjustment" button comes in two types: push-button and rotary knob, varying by car model. 2. Temperature Adjustment Buttons: These buttons adjust the air conditioning temperature, with most models using a rotary knob for adjustment. 3. Internal/External Air Circulation: This toggles between internal and external air circulation. 4. Window Defogging: The front windshield defogging symbol is fan-shaped, while the rear windshield defogging symbol is rectangular.
Let me share my experience about turning on the AC immediately after starting the engine. It's doable - pressing the AC control button right after startup is fine, as modern car designs have accounted for this, with systems automatically coordinating. However, note that when the engine is still cold upon startup, activating the compressor increases engine load, potentially causing slight idle instability or sound changes. Once in winter, I hastily turned on the heater after starting, resulting in slow cabin warming and some vibrations. Later, I developed the habit of letting the car warm up for 20-30 seconds after starting, waiting until the dashboard water temperature gauge begins moving before activating AC - this feels smoother and is gentler on the vehicle. This is especially advisable for older cars or extremely cold weather. Regarding the battery, since the alternator is working after startup, using AC has minimal impact. Safety isn't an issue; the key is optimizing habits by avoiding immediately setting high fan speeds.
