How to Turn on the Car Air Conditioning Heating?

To turn on the car air conditioning heating, follow these steps: 1. Start the engine and allow it to warm up until the temperature gauge needle reaches the middle position. 2. Turn on the heating function of the air conditioning system and set the air circulation to external mode to expel the cold air from the car. 3. After 2 to 3 minutes, switch the air circulation to internal mode. The car air conditioning system is an air conditioning device installed in vehicles, and its functions include: 1. Cooling, heating, ventilating, and purifying the air inside the cabin. 2. Providing a comfortable environment for passengers. 3. Reducing driver fatigue and improving driving safety. The components of a car air conditioning system are: compressor, electronically controlled clutch, condenser, evaporator, expansion valve, receiver-drier, pipelines, condenser fan, vacuum solenoid valve, and idle speed controller.

Turning on the car's heating system is quite simple. First, start the vehicle and let the engine run for a few minutes to allow the coolant to generate heat. Then locate the temperature knob on the center console and turn it to the highest setting (usually marked in red or as HIGH). Next, adjust the fan speed button to start airflow—avoid setting it too high, as gradual warming is more energy-efficient. Set the airflow direction: choose footwell or front vents to avoid direct blowing on the face, ensuring a more comfortable drive. If you have automatic climate control, just press the AUTO button. In winter, avoid using recirculation mode immediately; first, switch to fresh air mode to prevent window fogging. Keep the temperature around 20°C (68°F)—excessive heat can cause drowsiness. Regularly checking coolant levels and air filters also helps maintain heating efficiency.

As a new driver who just got my license, I recently figured out how to turn on the heater: After starting the car, wait a minute or two to let the engine warm up, then just idle to accumulate heat. Then, find the air conditioning control panel, turn up the temperature (look for the red scale), and set the fan speed to a moderate level like first or second gear. I usually direct the airflow toward the feet, which warms the whole body without drying out the eyes. Don’t forget, if your car has an automatic mode, just press the AUTO button for convenience. In cold weather, prioritize the external circulation mode to keep the air flowing and prevent fogging. Be careful not to set the temperature too high—around 25°C is optimal, as higher settings can increase fuel consumption. Also, remember to turn off the heater before parking to save energy.

The heater switch is crucial for driving safety, especially when family members are in the car. After starting the engine, wait patiently for a few minutes to allow it to warm up before turning on high fan speed to prevent malfunctions. Adjust the temperature to the highest red mark, keeping the fan speed below the third level. Set the airflow direction to foot or windshield mode to prevent fogging. In winter, briefly activate the air conditioning button to dehumidify and reduce fog. Prioritize external air circulation to maintain cabin air quality. Maintain a moderate temperature between 20-24°C to avoid driver fatigue. Develop a habit of regularly checking the cooling system.
