Before diving into the costs, let’s look at the components of a car AC system. According to a study by the University of Michigan’s Automotive Research Center in 2022, understanding these parts can help you diagnose problems more effectively.

Compressor: Pressurizes the refrigerant gas.
Condenser: Cools the refrigerant and releases heat.
Dryer (Receiver Drier): Removes moisture from the refrigerant.
Expansion Valve/Orifice Tube: Regulates refrigerant flow, reducing its pressure and temperature.
Evaporator: Cools the air that passes over it, located behind the dashboard.
Refrigerant Lines: Hoses that carry refrigerant between components.
