Is it okay to keep the air conditioning on while parked in the car?

There is no problem with keeping the air conditioning on while parked in the car. Parking the vehicle with the air conditioning running can enhance passenger comfort inside, especially during hot summer months. When using the air conditioning, it is necessary to utilize the external circulation system. Turning on the air conditioning system: First, start the vehicle, then press the AC switch. At this point, the air conditioning system will operate. Adjust the temperature via the air conditioning control panel, regulate the airflow through the gear settings, and adjust the vent angles to use it normally. Automatic air conditioning: For vehicles equipped with automatic air conditioning, simply press the AC switch, and the system will adjust automatically.
I often rest in my car with the air conditioning on while parked, especially on hot days or when waiting, which feels quite comfortable. However, this actually carries risks. If you're in an enclosed garage or parking lot, exhaust fumes from the engine can accumulate, containing colorless and odorless carbon monoxide, which can lead to poisoning or even be fatal if inhaled. Even in open outdoor areas, running the air conditioning consumes more fuel, wasting money and increasing expenses. Additionally, idling the engine to run the AC places a heavy burden on the battery, potentially draining it completely and requiring a tow for repairs. I recommend only using the air conditioning in well-ventilated areas for short periods, such as no more than 20 minutes, then turning off the engine and opening the windows for fresh air. It’s even safer and more eco-friendly to use sunshades or park in the shade to cool down. Make it a habit not to stay in the car for too long—safety should always come first.
As an experienced driver, I find that idling with the AC on in the car is not a good idea. I remember once seeing a driver napping with the engine running on the roadside, which almost led to an accident—it still gives me chills. Carbon monoxide in the exhaust is particularly dangerous and can accumulate in poorly ventilated areas, posing health risks. Running the AC outdoors also wastes fuel, adding significant expenses when gas prices are high, and increases your carbon footprint, which is unfriendly to the environment. Long-term idling can also cause carbon buildup in the engine, reducing its lifespan and leading to costly repairs. I believe that for short breaks, turning off the engine and using a fan or opening the windows for ventilation is safer and more efficient. If it's really hot, parking in the shade or carrying a bottle of water to quench your thirst is more cost-effective and hassle-free than running the AC. Safety should always come first when driving—don’t risk big losses for small gains.
