Does starting the car with the air conditioner on have any impact? When restarting without turning off the air conditioner, it increases the starting load, which may lead to premature battery failure and also increases wear on the starter. Below are relevant details: 1. Precautions: Before turning off the car, all functional buttons, including the air conditioner, should be turned off. Turning off the air conditioner two minutes before shutting down the engine allows the cold air in the pipes to be discharged in time, preventing mold and bacterial growth in the pipes. The air blown out by the air conditioner is directly breathed by the occupants inside the car, and bacterial growth can cause certain harm to their health. Therefore, it is advisable to turn off the air conditioner before shutting down the engine. 2. Composition of the air conditioner: The car air conditioning system consists of an air conditioning compressor, high-pressure pipes, a condenser, a dryer, high-pressure pipes, an expansion valve, an evaporator, and low-pressure pipes.
