Car AC Inspection & Fault Diagnostics
Our inspection helps identify why your car air conditioning is not cooling or operating correctly. Depending on the symptoms and system condition, checks can include:
- Air conditioning performance testing
- High- and low-side pressure checks
- Assessment for signs of low refrigerant
- Compressor operation testing
- Cooling fan and airflow checks
- Electrical controls and relevant sensor checks
- Vent temperature testing
- Refrigerant leak detection, including Trace-A-Gas testing where required
We explain our findings and quote for any recommended repairs or servicing before proceeding. If the system is suitable for a recharge, we also provide R134a regas and R1234yf regas as separately quoted services.

Car Air Conditioning Fault Checklist
Before recommending repairs, we check:
- System pressure behaviour
- Compressor engagement
- Signs of low refrigerant or system contamination
- Electrical signals to AC system
- Fan and airflow performance
- Signs of refrigerant leaks
- Temperature output from vents
Where refrigerant loss is suspected, we use pressure testing and Trace-A-Gas leak detection to help locate the source of the leak.
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 replaces refrigerant, but it does not repair a leaking component, electrical fault or mechanical failure.
We inspect and test the system to help identify the cause, then explain whether your vehicle needs a regas, a repair or further investigation.
Our Diagnostic Process
We follow a structured step-by-step process:
1. System Inspection
Visual check of all major AC components
2. Pressure Testing
