How to Use Car Air Conditioning in Cold Weather?

How to use car air conditioning in cold weather: First, let the vehicle run for a while until the water temperature gauge reaches half of the normal operating temperature, then start using the heater. Initially, use the external air circulation mode to allow fresh air to circulate inside the car for a few minutes before switching to internal air circulation. Car air conditioning is designed to regulate and control the temperature, humidity, air cleanliness, and air flow within the vehicle to provide a comfortable environment for passengers. Different types of air conditioning systems have varying layouts. Currently, most passenger cars use an integrated heating and cooling air conditioning system, where components such as the evaporator, heater core, centrifugal blower, and control mechanisms are assembled together, forming what is known as the air conditioning unit.
Using the air conditioning in cold weather isn't actually difficult. I'm accustomed to waiting patiently for three to five minutes after starting the car to let the engine and water temperature rise. Press the AUTO button to set a comfortable temperature, say 22 degrees, with the vents pointing downward or toward the windshield for quick defogging and warmth retention. Remember not to press the AC button—the cooling compressor is unnecessary in winter and only wastes fuel. Turn on recirculation mode to heat up faster, but it's best to crack the window slightly for ventilation to prevent stuffiness. Regularly check the cabin air filter and replace it if it's too dirty to avoid bacterial growth. These small habits make driving warm and worry-free while also extending the vehicle's lifespan.
As an experienced driver, there are some tricks to operating the air conditioning in cold weather. Wait for the coolant temperature gauge to stabilize at the midpoint before turning on the heater. If equipped with automatic function, use AUTO mode and set the target temperature - it will adjust fan speed automatically. Avoid pressing the AC button to prevent extra load, and set fan speed to medium for optimal defrosting effect. Check airflow direction to ensure smooth ventilation, and use external air circulation to introduce fresh air for better fuel efficiency and environmental protection. During each maintenance service, have the technician inspect the air conditioning system to prevent unexpected issues and ensure a smoother driving experience.
For safety first, use the air conditioning to defog and defrost when driving in cold weather. After starting the vehicle, wait for the engine coolant to reach normal temperature before turning on the heater, and direct the vents toward the windshield to remove ice. Set the temperature within a comfortable range, such as around 20 degrees Celsius, and avoid using too high a fan speed to prevent catching a cold. Use the recirculation mode for quick heating but switch to fresh air mode periodically. Regularly clean the air filter to avoid malfunctions that could impair visibility. This operation ensures clear driving vision, keeps you warm, and guarantees a safe journey.
