What are the precautions for using car air conditioning?

Precautions for using car air conditioning: 1. Do not turn on the heating air conditioning immediately when warming up the car in the morning. Wait until the engine coolant temperature rises before turning on the air conditioning; 2. Do not set the air conditioning temperature too high. Prolonged exposure to excessively hot temperatures can cause drowsiness and affect driving. Also, avoid directing the warm air directly at your face; 3. If the windows start to fog up after turning on the heating, increase the fan speed and let it blow for a while longer. This will make the fog disappear and prevent it from recurring; 4. During long-distance driving, ventilate the car periodically. Poor air circulation in a confined space can lead to breathing difficulties for the occupants over time; 5. Turn off the air conditioning before parking and switch to the external circulation mode with natural air. This helps clean the air conditioning system's ducts and prevents bacterial growth.

Having driven for so many years, using the air conditioning smoothly is crucial. Don't rush to turn on the cold air as soon as you get in the car. Starting the AC right after the engine fires up can add unnecessary strain, potentially leading to premature system aging. On hot summer days, it's advisable to open the windows for a minute or two to let the hot air out before turning on the AC. This ensures even cooling inside the car and prevents sudden temperature shocks to your body. If idling for extended periods while parked, it's best to turn off the AC to save fuel and reduce emissions. On highways, using the AC is actually more fuel-efficient than driving with windows down. Additionally, remember to replace the AC filter regularly—once a year is sufficient. A clogged filter reduces airflow and worsens cabin air quality, increasing the risk of colds. If you notice odd smells, check for refrigerant leaks or moldy pipes, as unresolved issues can compromise driving safety by causing fatigue. Make it a habit to switch between recirculation and fresh air modes every half hour to maintain air freshness and prevent dryness or allergies.

I always pay attention to maintaining the air conditioning system. After starting the vehicle, don't press the cooling button immediately; wait until the engine runs smoothly before turning it on to protect the compressor's lifespan. For automatic air conditioning, just press the AUTO button for intelligent adjustment, which is worry-free and energy-saving. The key is regular inspections - replace the filter every 5,000 kilometers or every six months, and it's simple enough to do it yourself. If you notice reduced airflow or insufficient cooling, it might indicate insufficient refrigerant or blocked pipes, requiring professional inspection. Don't forget the defrost function in winter, and set reasonable temperatures to avoid excessive temperature differences that could damage the system. Paying attention to these maintenance details extends equipment life while saving money and being eco-friendly. Turn off the air conditioning a few minutes before parking to allow the interior to dry, reducing bacterial growth. Focusing on these aspects makes for a more comfortable and healthier driving experience.

Focus on comfort, I keep the air conditioning at a moderate level while driving to avoid excessive cold. Setting the temperature around 23 degrees is most comfortable, especially when children or elderly passengers are on board. Avoid direct airflow to the face to prevent chills or dry skin; after starting the car, use the external circulation first to bring in fresh air, then switch to internal circulation to maintain a constant temperature and reduce dust allergens. Replace the filter when it's dirty to prevent bacterial spread and respiratory health issues. The dehumidification function is crucial on rainy days to prevent foggy windows and blurred vision. Remember to take breaks, turn off the AC, and open windows for fresh air to prevent fatigue. These small habits make the journey safe and enjoyable.
