Can the air conditioning be left on while the car is running?

It is possible to keep the air conditioning on while the car is running, but it is not recommended to do so frequently. On one hand, it leads to higher fuel consumption, and on the other hand, idling can cause the engine to accumulate carbon deposits more easily, which may degrade engine performance over time. Tips for using air conditioning: After the car has been exposed to the sun for a long time, you should first open all four doors and the sunroof to allow air to circulate inside the car for about 3 minutes. This will quickly lower the interior temperature, making the air conditioning more effective when turned on. Using the recirculation mode blocks hot outside air, creating a sealed space inside the car, allowing the air to circulate rapidly under the effect of the air conditioning for faster cooling. Once the interior temperature has dropped, it is recommended to switch to the fresh air mode every 30 minutes to purify the air inside the car, then switch back to recirculation mode after 5 minutes. Turn off the air conditioning about 5 minutes before parking to protect the engine and save fuel. Hazards of prolonged idling: When the car is idling, incomplete combustion of gasoline produces a significant amount of carbon monoxide. The longer the idling time, the higher the concentration of carbon monoxide around the vehicle. Prolonged idling can result in extremely high carbon monoxide levels inside the car, which can lead to carbon monoxide poisoning or even death if passengers are present, potentially causing safety accidents. Therefore, it is important not to keep the windows completely closed. Instead, open them slightly to maintain air circulation between the inside and outside of the car.
