Does idling with AC on in summer damage the car?

[MacIsabelle]

It does not cause any special damage to the car, only normal wear and tear. Below are the impacts of idling with AC on: 1. Increased emission of harmful gases: Idling with AC on emits more harmful exhaust gases compared to driving with AC on, because idling is the most unfavorable operating condition for the engine, where gasoline combustion is relatively incomplete, resulting in higher emissions of carbon monoxide, hydrocarbons, nitrogen oxides, and other harmful gases. 2. Significant harm to human health: Idling with AC on can cause harm or even death to occupants if not careful. There are mainly two types of harm: one is hypoxia and suffocation, and the other is carbon monoxide poisoning. When idling with AC on, it must be done in an open area. Never stay in the car for a long time in a confined small space, as the carbon monoxide emitted by the car can enter the vehicle, easily leading to carbon monoxide poisoning.
