Car Air Conditioning Fault Checklist
Before recommending repairs, we check:

- Refrigerant condition
- Electrical signals to AC system
- Fan and airflow performance
- Signs of refrigerant leaks
- Temperature output from vents
We use pressure testing and trace gas leak detection methods where required to identify hidden leaks.
Common Car Air Conditioning Problems
- Air not cold enough
- Air blowing warm
- AC works while driving but not at idle
- Weak airflow from vents
- AC cycling on and off
- Strange noises when AC is on
- Bad smell from vents
Important Diagnostic Information
Car air conditioning systems are complex and rely on:
- Refrigerant pressure balance
- Electrical controls
- Mechanical compressor operation
- Proper airflow through condenser and cabin system
A regas alone will NOT fix most faults.
Correct diagnosis is required before repairs are recommended.

1. System Inspection
Visual check of all major AC components
2. Pressure Testing
High and low pressure readings assessed
3. Electrical Testing

Vent temperature measured under load
5. Leak Detection (if required)
Trace gas method used to locate refrigerant leaks
