Does Running the Air Conditioner While Parked Affect the Car?

[LaPiper]

Running the air conditioner while parked can harm the car. Here are the detailed explanations: 1. Effects: Operating the air conditioner while the car is idling increases fuel consumption and can lead to more engine carbon buildup. While the air conditioner compressor is indeed driven by the engine, the blower fan is powered by the battery. During idling, the car may not necessarily charge the battery, and excessive use of the blower fan can drain the battery, potentially causing long-term battery depletion. 2. Functions of the Air Conditioner: Temperature Control: In summer, the cooling system produces cold air to lower the cabin temperature; in winter, except for large commercial vehicles that use independent combustion heaters, most vehicles rely on residual heat for warming. Humidity Control: Cabin humidity should generally be maintained between 30% and 70%. Airflow Adjustment: Airflow speed can be adjusted based on passengers' living environment, age, health, and temperature preferences. Air Purification: The quality of cabin air is crucial for comfort.
