1. Understanding Your Car’s AC System
Before diving into the costs of AC service, let’s understand the basics of your car’s air conditioning system, often called HVAC (Heating, Ventilation, and Air Conditioning), which goes beyond simply blowing cool air. It manages temperature, airflow, and air quality inside your vehicle.
Here’s a breakdown of the main components:
- Compressor: The heart of the system, compressing refrigerant and circulating it.
- Condenser: Cools the hot, high-pressure refrigerant gas, turning it into a liquid.
- Evaporator: Absorbs heat from inside the car, cooling the air that blows into the cabin.
- Expansion Valve or Orifice Tube: Controls the flow of refrigerant into the evaporator.
- Refrigerant: The substance that absorbs and releases heat as it cycles through the system.
- Cabin Air Filter: Cleans the air entering the cabin, removing dust, pollen, and pollutants.
