Do you need to turn on the AC for car heating?

[LeKatherine]

You do not need to turn on the AC for car heating because: The AC button controls the compressor switch, while the heating system utilizes the internal heat circulation of the car to maintain the cabin temperature. The method to turn on car heating is as follows: 1. Start the engine and allow it to warm up until the temperature gauge reaches the middle position; 2. Turn on the heating system and set the air circulation to external mode to expel cold air from the cabin; 3. After 2 to 3 minutes, switch the air circulation to internal mode. The car air conditioning system is an installed air conditioning device that serves the following purposes: 1. It can cool, heat, ventilate, and purify the air inside the cabin; 2. It provides a comfortable environment for passengers; 3. It reduces driver fatigue and enhances driving safety.
