Most car AC failures start with refrigerant leaks. Improper refilling can damage the compressor, so diagnosis and charging belong in specialist shops.
Car AC repairs are expensive, and timely maintenance protects drivers from major failures and costs. Because the system is complex, diagnosis is best left to workshops that specialise in climate systems.
- Most failures are caused by refrigerant leaks, which let moisture and air into the system.
- A shortage of refrigerant means poor lubrication and, over time, compressor failure.
- Expansion valves, electromagnetic clutches and pressure switches can also fail.
MSG Equipment emphasises that professional charging and diagnostic equipment is essential to fill the system with the correct amount and follow the right procedure.
