How to Turn on the Car Air Conditioner?

[McBennett]

Method to turn on the car air conditioner: 1. Start the car, turn the temperature control knob to the cold side (blue end), turn on the AC switch and the fan (with settings 1-4), and you can also turn on the internal circulation; 2. In winter, turn the temperature control knob to the hot side (red end) and turn on the fan switch to get warm air. Method to turn off the car air conditioner: Set the fan speed switch to 0 to turn off the air conditioner. If the owner wants to turn off the cooling function while keeping the fan on, simply turn off the separate cooling switch. If you want the car air conditioner to produce heat in winter, switch the cooling/heating conversion switch to the heating area, turn on the fan switch, and adjust the fan speed to the desired setting. When heating, the cooling switch must be in the off state.

After starting the car, locate the air conditioning button or switch on the dashboard, usually marked with a snowflake or fan icon. Press the power button to turn it on. For manual AC, rotate the temperature knob to the cooling zone (blue section), adjust the fan speed knob to your preferred intensity, and select the airflow direction toward the windows or body area. Many newer cars feature an AUTO mode—just press it for automatic adjustment, eliminating the need to constantly monitor temperature changes. I always roll down the windows for a few minutes in summer to dissipate heat before turning on the AC, preventing fan overload. Also, pay attention to using recirculation mode: switch to internal circulation in traffic to block exhaust fumes, and toggle to external circulation on highways for fresh air. Don’t forget to clean the filter regularly to prevent odors—replacing it every six months saves more energy.

I operate the AC quite casually. Start the car, then press the fan button to activate the system. My car's controls are simple: the left knob adjusts temperature, the middle one controls fan speed, and the right selects airflow direction like windshield or seats. In hot weather, I prefer setting the temperature lower but not too cold to avoid catching a cold from the drastic temperature difference; in winter, I do the opposite and turn on the heat. Running the AC for long periods consumes fuel, so during city commutes, I don't keep it on continuously, alternating with window ventilation to save money and be eco-friendly. Occasionally checking refrigerant and filters is common sense—reduced airflow might indicate a blockage, easily fixed with compressed air.

Turning on the AC is part of my daily routine. Start the engine, press that AC button to activate cooling or heating mode, then use the knobs to adjust to your preferred temperature and fan speed. I usually switch to external circulation for a few minutes to air out the cabin before switching to internal circulation to maintain a constant temperature, avoiding direct cold airflow discomfort. For foggy conditions, turning on the AC for quick dehumidification works best. Regular cleaning of the AC filter (about twice a year) helps prolong the system's lifespan.

I'm especially cautious with the air conditioning when driving my family. As soon as the engine starts, I press the button to activate the system and set an appropriate temperature, around 25°C, to prevent the kids from getting cold. I adjust the fan speed to medium to avoid noise interference with conversations. I often use the automatic mode for convenience, but on long trips, I manually fine-tune the airflow direction towards the windows to defog them. Safety comes first—I avoid keeping the AC on for too long while idling to prevent carbon monoxide buildup. During heatwaves, I ventilate the car first before turning on the AC to prevent heatstroke. Checking that the compressor sounds normal is crucial; any squeaking noise means it's time for a check-up.
