Does prolonged idling with the air conditioning on affect the car?

[JaxonLee]

Keeping the air conditioning on while idling for extended periods will increase fuel consumption and, over time, can lead to carbon buildup in the engine. When the engine is running, if the gasoline in the cylinders does not burn completely, it produces high concentrations of carbon monoxide. If this carbon monoxide leaks into the car's interior, its concentration can gradually increase, leading to poisoning and, in severe cases, even suffocation and death. The air conditioning system is designed to ventilate, purify, cool, and heat the cabin, providing a comfortable environment for passengers, reducing driver fatigue, and enhancing driving safety. Prolonged idling with the air conditioning on not only accelerates engine wear but also keeps the air conditioning in recirculation mode, which can cause the air inside the car to become increasingly polluted, raising harmful gas levels and posing health risks.
