How to Turn on the Car Air Conditioner in Summer?

First, open the windows to let the original air inside the car escape, then turn on the air conditioner and set it to internal circulation to quickly lower the temperature. After a while, switch to external circulation to maintain air flow. When using the air conditioner, position the air vents upward because cold air tends to sink. By directing the vents upward, you take advantage of this principle. Below are four functions of modern car air conditioners: 1. The air conditioner can control the temperature inside the cabin, heating or cooling the air to maintain a comfortable level. 2. The air conditioner can remove humidity from the air. Dry air absorbs sweat from the body, creating a more comfortable environment. 3. The air conditioner can draw in fresh air, providing ventilation. 4. The air conditioner can filter the air, removing dust and pollen.
In summer, my method of using the air conditioning in the car is to start the engine first and wait about 30 seconds for it to stabilize. Then press the AC button; if the car has an AUTO button, just press it, and the system will automatically set the temperature and fan speed. Next, adjust the temperature knob, usually around 25 degrees is fine—don't set it too low to avoid overloading the engine, increasing fuel consumption, or catching a cold. Start with a higher fan speed to cool the car quickly, then after a few minutes, adjust it lower either automatically or manually. Remember to switch between recirculation and fresh air modes: use fresh air mode initially to let in some fresh air and ventilate to remove humidity, then switch to recirculation mode once the temperature stabilizes to save energy, but don't use recirculation for too long as it can make the cabin stuffy and cause dizziness. Before parking, turn off the AC a few minutes early to remove humidity and prevent condensation buildup. For regular maintenance, change the cabin air filter periodically—clean it every six months to prevent odors and air pollution. Also, after the car has been parked in the sun, don’t rush to turn on the AC; first, open the windows for a minute to ventilate and dissipate heat, which will help cool down the car faster.
I prefer using the one-touch auto climate control in my car. After starting the engine, I immediately press the AUTO button and set the temperature to 24°C, which feels most comfortable. The automatic fan speed adjustment is convenient – it blows stronger when it's hot to cool down faster. Don't forget to toggle the air recirculation button; use interior circulation in city traffic to avoid exhaust fumes, but switch to exterior circulation every 20 minutes for fresh air. Before turning on the AC, it's best to open windows for dozens of seconds to vent hot air – this cools faster and saves some fuel. Avoid setting temperatures too low (below 20°C) as it increases engine load and fuel consumption. Check the cabin air filter every six months – replace if dirty to ensure strong airflow and fresh air. Normally, no unusual noises from the AC indicate proper system operation. Also, don't blast AC immediately after parking in the sun; gradual cooling prevents physical discomfort. Finally, switch to exterior circulation before turning off the AC to prevent residual moisture and mold formation.
