Understanding Car AC Components

It's a complex network of components designed to cool, dehumidify, and circulate air.

Compressor

It's the heart of the system, compressing refrigerant for cooling.

Condenser

Cools refrigerant by releasing heat outside.

Evaporator

Removes heat from the cabin.

Expansion Valve/Orifice Tube

Controls refrigerant flow.

Refrigerant

The cooling fluid (R134a or R1234yf in newer cars).

Hoses and Seals

Connect all parts and maintain pressure.

Common Car AC Problems

Low Refrigerant/Leaks

Symptoms: Weak cooling, hissing noises, or frost on evaporator lines.

Repair: Regas (recharging) + Leak repair.

Typical Cost in Perth: AUD $150–$300

Faulty Compressor

Symptoms: AC blows warm air, loud clunking noises, and AC cycles on/off.

Repair: Compressor replacement (plus refrigerant and oil).

Typical Cost in Perth: AUD $700–$1,500

Clogged Condenser

Symptoms: Reduced cooling efficiency, overheating under the hood.

Repair: Cleaning or replacement.

Typical Cost in Perth: AUD $300–$600

Electric or Sensor Issues
