How to Turn on the Car Air Conditioner for the Coolest Effect?

First, open the car doors and windows for ventilation, then turn on the external air circulation of the air conditioner. Wait until the temperature inside and outside the car is similar, then close the windows and switch to internal air circulation. Turn on the air conditioner and adjust the vents upward to facilitate convection of hot and cold air inside the car, thereby increasing the cooling speed.
To achieve the coolest air conditioning, based on daily experience, I would start the engine and immediately turn on the AC, setting it to the lowest temperature with the highest fan speed, ensuring the recirculation mode is on to prevent hot outside air from entering. In summer, try to park in shaded areas or open the windows for a few minutes to let heat escape before closing them and turning on the AC, which speeds up cooling. Additionally, don’t forget to regularly clean the AC filter—dirt buildup can block airflow, reducing cooling efficiency and causing odors. Check if the refrigeration system is functioning properly; insufficient refrigerant can weaken AC performance, so it’s best to have it inspected annually by a professional. Directing the airflow toward the head is most effective for cooling, while avoiding prolonged dashboard exposure to sunlight prevents interior heat buildup. This approach not only enhances driving comfort but also saves fuel. Before long trips in hot weather, trying this method makes a noticeable difference, and maintenance is straightforward.
