Is it okay to keep the air conditioning on when the car is not running?

Keeping the air conditioning on when the car is not running is very dangerous. When the car's engine is running, if the gasoline in the cylinders does not burn completely, it produces high concentrations of carbon monoxide. If the air inside the car cannot circulate, the carbon monoxide emitted by the engine can leak into the car, gradually accumulating and increasing its concentration, leading to poisoning. Here is some information about car air conditioning: 1. Introduction: The car air conditioning device (air-conditioning-device) is referred to as car air conditioning. 2. Function: It is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to the optimal state, providing passengers with a comfortable riding environment and reducing travel fatigue; it also creates good working conditions for the driver and serves as an important ventilation device for ensuring safe driving.
As someone who has been driving for over a decade, I can tell you from personal experience that keeping the air conditioning on while the car is stationary is definitely not a good idea. One summer when I was waiting for a friend and wanted to cool off in the car, I left the AC running for half an hour, and the battery died completely, leaving me unable to start the car. I had to call for roadside assistance and pay to get it fixed. The main reason is that the air conditioning relies on the battery for power, and if the car isn't running, the alternator doesn't work, which can easily drain the battery. Doing this long-term can also cause excessive wear on the compressor, increasing maintenance frequency. Additionally, if you run the AC with the engine on, fuel consumption rises quickly, wasting gasoline unnecessarily. So, I recommend keeping the AC use to a minimum—no more than ten minutes—or simply opening the windows for ventilation. If you really need to cool down, try using the fan mode instead.
From an environmental perspective, this issue deserves more attention. Keeping the car's air conditioning running while the vehicle is stationary wastes energy and creates pollution. Engine idling emits more exhaust, which is harmful to both air quality and the climate. We should advocate for fuel conservation and carbon emission reduction, such as pre-cooling the car only before driving rather than running the AC for extended periods while parked. Actually, using fans or opening windows while waiting in parking lots can save significant resources. This habit also protects the environment, making cities fresher. In short, for the sake of our planet, let's avoid developing such wasteful habits.
