Does the AC light indicate cold air or hot air?

When the AC light is on, it indicates cold air. The AC button serves as the switch for the air conditioning compressor, which is one of the main components of the air conditioning refrigeration system. It compresses and transports refrigerant vapor. When the AC light is illuminated, it means the cold air is activated. The cold air is produced by pressurizing the refrigerant through the compressor, causing it to liquefy and then vaporize, absorbing a significant amount of heat from the air in the process. AC stands for air conditioning, a system designed to regulate and control the temperature, humidity, air cleanliness, and airflow inside the vehicle cabin to create a comfortable environment for passengers, reducing travel fatigue. It also provides optimal working conditions for the driver, playing a crucial role in ensuring safe driving as part of the ventilation system.
