What kind of air conditioner should I turn on in the car when it’s cold?

When the weather is cold, turn on the heater in the car.

There are generally two methods. One is to preheat first and start the engine before getting in the car. Let the engine reach sufficient heat before turning on the air conditioner. The second is to save travel time. Drive for a few minutes before turning on the air conditioner. This will allow your car to "focus" on driving instead of spending more "energy" to help you operate the air conditioner.

Notes on the use of car air conditioners:

1. Do not turn on the heating air conditioner immediately when warming up the car in the morning. Wait until the water temperature in the engine water tank rises before turning on the air conditioner.

2. Do not set the air conditioner temperature too high. Overheating for a long time will make you sleepy and affect your driving. In addition, do not let the warm wind blow directly on your face.

3. If the car windows start to fog up after turning on the warm air, most people will turn off the warm air or use cold air to drive away the fog. This will cause repeated fogging, so the warm air speed should be increased. Blow for a while longer so that the fog disappears and will not reappear.
