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

[DelJeffrey]

Prolonged idling with the air conditioning on does affect the car. Running the air conditioning for extended periods increases fuel consumption, and over time, the engine is prone to carbon buildup. When the engine is running, incomplete combustion of gasoline in the cylinders can produce high concentrations of carbon monoxide. If this carbon monoxide leaks into the car, it can accumulate and reach dangerous levels, potentially leading to poisoning or even fatal suffocation. 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. However, prolonged idling with the air conditioning on not only causes engine wear but also keeps the air conditioning in recirculation mode, leading to increasingly stale air inside the car, which can increase harmful gas levels and endanger human health.
