How Long Can You Run the Air Conditioner While Parked?

[AshlynMarie]

It is advisable to run the air conditioner for about 15 minutes when parked. Prolonged use can lead to poor heat dissipation and damage to the car engine. In relatively enclosed environments, such as garages, it may even cause carbon dioxide poisoning. It is best to use the air conditioner in open or well-ventilated areas and leave a small window gap for airflow. When parked, the engine operates at idle speed, resulting in lower RPM and reduced intake pressure. In this state, the engine increases the throttle opening to compensate, which also increases fuel injection. Here are some precautions for using the car air conditioner: 1. Maintain fresh air: Shortly after entering the car, open the windows or activate the external air circulation system to introduce fresh air. Avoid driving for long periods with closed windows and doors, and never sleep or rest for extended periods in a sealed car. 2. Ensure air exchange: After purchasing a new car, treat it like a newly renovated house by maximizing air exchange between the interior and exterior. This helps release harmful gases from the car's interior as quickly as possible.
