Is it necessary to turn off the air conditioning when parking?

[TuckerFitz]

It is necessary to turn off the air conditioning when parking. Otherwise, it will slightly affect 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, mold can grow over time, leading to unpleasant odors and even affecting health. Additional information: Not turning off the air conditioning has no impact on the engine. This is because the compressor does not rotate during startup, so it does not add unnecessary load to the starter. When the vehicle starts, almost all electrical appliances 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 does not start. After the vehicle starts, the compressor will begin working in about three to five seconds. For compressors with an electromagnetic clutch, you can hear a clicking sound, which is the sound of the compressor engaging.
