Does leaving the AC on after parking have any impact?

Leaving the AC switch on after parking can easily lead to battery drain. The function of AC: The AC button in the car is the switch for the air conditioning cooling system. When the weather is hot and you need to turn on the air conditioning to cool down, press the AC button, and the indicator light on the button should illuminate. The car's air conditioning compressor starts working, and cold air blows out from the vents, lowering the temperature inside the car. This provides a comfortable riding environment for passengers and reduces travel fatigue. How to use AC: When cooling is needed, press the AC button and adjust the temperature selection switch to the blue section, then turn on the fan switch. Only then will cold air blow out.
As a veteran driver with ten years of experience, I often make the mistake of not turning off the AC when parking, which has caused me quite a bit of trouble. The most frustrating issue is the battery problem. Leaving the AC on continues to drain power, especially on hot days when the compressor is still running. If the car is parked for an extended period, the battery can be completely drained, making it difficult to start the engine. Last month, my battery burned out because of this, and replacing it cost me several hundred bucks—what a pain! Actually, turning off the AC a minute or two before shutting down the engine allows the fan to blow out the remaining cool air, protecting the system and avoiding sudden load during the next ignition. Developing this small habit can save a lot on maintenance costs in the long run. If the battery is frequently undercharged, it can also damage other components, such as the alternator, which has to compensate. In short, turning off the AC when parking is a smart move to avoid unexpected troubles.
