What are the hazards of long-term idling with the air conditioning on in a car?

[LeAlex]

The main hazards of long-term idling with the air conditioning on in a car are: 1. It can cause incomplete combustion in the engine, increasing carbon deposits inside the engine and leading to wear and tear on car components. 2. It can result in incomplete gasoline combustion, producing toxic substances such as carbon monoxide. If the air conditioning is left on during prolonged idling, people inside the car may experience carbon monoxide poisoning. 3. It can affect the vehicle's cooling system. When the vehicle is in the ignition state, the engine is operating and generating heat. While driving, the movement of the vehicle creates some airflow, which helps dissipate part of the engine's heat. However, during idling, there is no such airflow assistance. The engine's heat can only be cooled by the vehicle's cooling system.
