Does idling with the AC on in summer affect the car?

[LeRachel]

First, idling with the AC on increases fuel consumption, and idling in place with the AC on may harm the occupants while also increasing carbon buildup. Because exhaust contains many harmful substances, the most dangerous to humans is carbon monoxide, a product of incomplete combustion, which is unavoidable. Carbon monoxide is produced the most when the vehicle is idling, and at this time, turning on the AC in place can easily draw it into the car, causing harm to the occupants. Additionally, for the car, idling with the AC on for too long places a heavy load on the engine, leading to a sharp increase in carbon buildup. Over time, excessive carbon buildup can affect various aspects of the car. Correct AC usage in summer: First, after getting in the car, open the windows. After the car has been exposed to the sun, it is essential to ventilate, as many materials inside the car can produce pungent and sometimes toxic gases under high temperatures. Then, turn on the fan to blow away the contaminated air in the AC system and also to expel the hot air from the system. Turn on the AC, use natural air for a few minutes first, then switch to cooling. After cooling for one or two minutes, close the windows.
