Turning off the engine before turning off the air conditioning means that during the next startup, the engine will start with the load of the air conditioning, which can cause damage to the engine due to the high load. Below are the related details: Hazards: Turning off the engine before turning off the air conditioning. The cold air remaining in the air conditioning ducts cannot be expelled, which can lead to the growth of a large number of bacteria. When the air conditioning is turned on next time, these bacteria can be easily inhaled into the body, causing respiratory diseases. Additionally, it can easily lead to battery drain. Best Practice: The best approach is to turn off the air conditioning a few minutes before reaching the destination. This allows the natural air to circulate, raising the temperature inside the air conditioning ducts and eliminating the temperature difference with the outside environment. This helps maintain the relative dryness of the air conditioning system and prevents the growth of mold.
