AC System
An AC System (Air Conditioning System) is the complete setup that controls temperature and air quality in vehicles. It includes various parts that work together to cool and dehumidify the air inside a car. When candidates mention AC System experience, they're referring to their ability to diagnose, repair, and maintain all components that make up a vehicle's air conditioning. This is a crucial skill in automotive repair, especially in warmer climates where AC repair makes up a significant portion of service requests. The term might also appear as "HVAC system" or "climate control system" in automotive contexts.
