Does Idling with Air Conditioning On Affect the Car?
1 Answers
This is a normal phenomenon. The reason why car windows often frost up in winter is due to the significant temperature difference between the inside and outside of the car. The air inside the car is more humid than outside, so when it comes into contact with the colder glass surface, it condenses into frost. Idling with the air conditioning on does not harm the car. Idling with the air conditioning running is a normal operating condition during regular car use. Automobiles are designed and manufactured with various usage scenarios in mind, so it does not cause any particular damage to the car, only normal wear and tear. Below is additional information: The hazards of idling with air conditioning on: When idling with the air conditioning on, the engine operates only at idle speed, leading to incomplete combustion of gasoline. Unburned gasoline produces toxic substances such as carbon monoxide. Additionally, occupants inside the car exhale large amounts of carbon dioxide. In summer, the hot weather causes higher oxygen consumption inside the vehicle compared to other seasons. As the oxygen level in the enclosed car gradually decreases, prolonged exposure can cause dizziness, nausea, and weakness in the occupants—clear symptoms of carbon monoxide poisoning. Therefore, in summer, never rest or sleep in an enclosed car with the air conditioning on for extended periods.
