Is it good to start a car with the air conditioning on?

Starting a car with the air conditioning on is not recommended. The compressor of the car's air conditioning system operates only when the engine is running. If the engine is started while the air conditioning is still on, it increases the load on the starter. Additionally, starting the vehicle with the air conditioning on requires more power, leading to higher current flow, which can cause overheating of wires and connectors, and may even blow the starter fuse. The car air conditioning system consists of a refrigeration system, heating system, ventilation and air purification devices, and a control system. The control system mainly comprises electrical components, vacuum lines, and operating mechanisms. Its functions include: 1. Controlling the temperature and pressure of the refrigeration and heating systems; 2. Managing the temperature, airflow, and direction of the air inside the car to enhance the performance of the air conditioning system.
I think it's not a good habit to keep the air conditioning on when starting the engine. This increases the battery load on the car, putting more pressure on the starter motor, which may shorten battery life or cause starting difficulties. Especially during hot summer weather, the air conditioning system requires a significant amount of power to start the compressor. Operating this way for a long time may also lead to engine vibration or higher fuel consumption. I've personally encountered several cases where car owners complained about premature battery failure, and upon inquiry, they all had the habit of not turning off the air conditioning when starting the engine. The best practice is to turn off the air conditioning and headlights and other electrical devices before starting the engine, and then turn on the air conditioning after the engine runs smoothly, which can protect the vehicle's key components.
