Can the air conditioning still be used after the engine is turned off?

Yes. However, there is no cooling function, and prolonged use can easily lead to battery drain. Here is the relevant information: 1. Impact on the engine: When starting the car, the compressor will not rotate, avoiding unnecessary load on the starter. This is because when the vehicle starts, almost all electrical appliances on the car are in a power-off state, with all current and voltage concentrated on the starter. The air conditioning panel also has no power, so the compressor naturally will not start. 2. Evaporator: There is a slight impact on the evaporator. If the air conditioning is not turned off in advance, water will remain on the evaporator. The evaporator is enclosed in a sealed box, making it difficult for the water to evaporate naturally, requiring a long time. Due to the dark and humid environment, prolonged exposure can lead to mold growth, unpleasant odors, and even affect health.
