How to Use the Car Air Conditioning?

Here is the correct way to use the car air conditioning: 1. Generally, the button on the left side of the car represents cold air in blue, warm air in red, and a moderate temperature in the middle. 2. To turn on the cold air, adjust the left button towards the blue area. For warm air, adjust it towards the red area and press the AC switch. The middle button controls the fan speed, and the one on the far right adjusts the mode, allowing you to direct airflow to the feet, hands, or windshield, or use a combination of modes. 3. It is best to turn on the internal circulation when using the cold air and the external circulation when using the warm air.

Last time my friend just bought a new car and asked me how to use the air conditioning. I told him, first find those buttons on the center console with snowflake and fan symbols. To cool down, press the AC button and turn the temperature knob towards the blue zone; to heat up, don’t press AC, just turn the knob directly to the red zone. Adjust the fan speed using the button with the fan symbol, and the air vent direction can be controlled with the knob to blow towards the head or feet. On rainy foggy days, remember to press the defog button, and the windshield will clear up quickly. Don’t turn on the AC immediately after starting the car; the engine isn’t warm yet. Opening the windows for half a minute before turning on the AC works better. The cabin air filter should be replaced regularly, otherwise the air coming out will have a musty smell, which isn’t good for breathing.

Before taking my kids out in summer, I always remotely start the car to cool down the air conditioning, so the seats won't be scorching hot when we get in. The automatic AC is quite convenient - just press the AUTO button to automatically adjust the airflow, and setting the temperature around 22°C feels most comfortable. For children sitting in the back, avoid direct airflow from the vents - I usually adjust the direction to blow upward. On long trips, remember to switch between recirculation and fresh air modes: use recirculation in traffic to block exhaust fumes, and switch to fresh air on highways for ventilation. Always turn off the AC first and let the fan run for a few minutes before shutting down the system, otherwise moisture buildup in the pipes can cause mold. It's best to replace the cabin air filter every six months to prevent allergies and sneezing.

Having driven ride-hailing cars for years, I've become quite familiar with the AC controls. There are just a few buttons: the left knob adjusts temperature, the right knob controls fan speed, and the center button manages vent positions. In summer, I first open windows for ventilation before turning on AC cooling - setting temperature between 22-24°C saves the most fuel. In winter, just turn on the heater without pressing AC. The defogger button works wonders when the windshield fogs up, showing effect within five seconds. Remember not to keep recirculation mode on too long as it may cause dizziness. On highways, always turn on rear vents for passengers to prevent overheating in the back.

Our repair shop often encounters air conditioning odor issues, but prevention is actually quite simple. Turn off the AC but keep the fan running for 2 minutes before shutting down the engine each time to drain moisture from the evaporator and prevent mold growth. Don't set the temperature too low - excessive temperature differences can easily cause colds, maintaining around 23°C is just right. Replace the filter twice a year, which you can do yourself: just open the glove compartment and unclip the fastener to access the filter. In winter, don't use AC for defogging - blowing hot air directly at the windshield works fastest. If cooling becomes slower, check the refrigerant level; if insufficient, have it professionally refilled as DIY attempts may cause refrigerant leaks.

I remember when I first started driving, I didn't even know how to use the defogging function of the air conditioning. Now I've learned that usage varies by season: After summer sun exposure, first open windows for ventilation before turning on AC, set temperature to 24°C with maximum fan speed for rapid cooling; In winter, wait until the coolant temperature gauge reaches mid-level before turning on heater, adjust temperature directly without AC; During rainy days, activate front windshield defogger and mirror heating. The AUTO mode of automatic climate control is particularly convenient, and can even be operated via steering wheel buttons. Remember not to point air vents directly at your face to avoid air conditioning sickness. Running maximum fan speed monthly helps clean air ducts, and turning off AC while keeping fan on before parking prevents musty odors.
