Should You Turn Off the Car Engine or the Air Conditioning First?
1 Answers
Turn off the air conditioning before shutting down the engine. If you turn off the engine directly, the next time you start the car, the engine will bear the load of the air conditioning. Prolonged operation in this manner can damage the engine. It is advisable to turn off the air conditioning a few minutes before shutting down the engine, allowing natural air to eliminate the temperature difference inside and outside the air conditioning ducts. This helps maintain the dryness of the air conditioning system and prevents bacterial growth. When using the air conditioning again, start the car and wait a few minutes before turning on the air conditioning for optimal performance. Tips for using car air conditioning: 1. Air conditioning vents: Many people direct the vents toward themselves whether using hot or cold air, which is not ideal. In summer, point the vents upward since cold air, being denser, sinks. This method helps cool the car interior more quickly. For warm air, pointing the vents upward allows faster heating of the car interior. Directing air toward oneself can cause dry skin, and bacteria from the vents may be inhaled, affecting health. 2. Switching between internal and external circulation: Flexibly using internal and external circulation while operating the car air conditioning helps maintain relatively fresh air inside the car, benefiting both the driver and passengers.
