Is it okay to run the air conditioning with the car idling?

[Harmony]

After starting the car, you can turn on the air conditioning without driving. Idling operation: After the vehicle is started and running at idle speed, turning on the air conditioning system allows it to operate normally without any adverse effects. However, the engine speed will increase slightly, fuel consumption will rise, and the engine noise will become louder. How to use car air conditioning: To use the air conditioning in a motor vehicle, first start the engine. After starting, press the AC switch to activate the air conditioning system. Adjust the air vent positions, set the fan speed, and adjust to the low-temperature zone for normal operation. For models equipped with automatic air conditioning, simply press the AUTO button, and the system will operate automatically. At this point, you only need to adjust the desired temperature to use the air conditioning normally.
