Our repair approach
Modern Equipment Supported by Experienced Technicians
Modern cars contain many electronic control units. Experience alone may not identify a fault, while fault codes also require interpretation using live data and physical tests. We combine advanced tools with experienced decision-making and workmanship.
We therefore use Computer diagnostics to read fault codes and live data, followed by systematic checks to identify the underlying cause instead of replacing parts blindly. Air-conditioning checks are free on site, with a clear quotation and approval before repairs.
- Diagnose the underlying cause before choosing the repair
- A complete 2.5-hour automatic air-conditioning cleaning process
- Diagnostic equipment for fault codes and live data
- Direct answers to technical questions from our team
- Routine maintenance helps prevent minor faults becoming major repairs
Air-conditioning specialists
Air-conditioning Specialists: 2.5-hour Automatic Closed-loop Cleaning
Air-conditioning repairs are our speciality. Compressor oil lubricates the compressor, helps seal the circuit and removes heat, but deteriorates through moisture absorption and oxidation. Adding refrigerant alone may offer only temporary improvement; contaminated oil must be removed and the correct fresh oil and refrigerant added where the diagnosis requires it.
Our automatic equipment performs a closed-loop cleaning process without manual dismantling. The 2.5-hour procedure includes cleaning, evacuation, leak testing and accurate charging. Each step receives the time it needs.
- Free on-site air-conditioning system checks
- Refrigerant pressure checks, condenser cleaning and evaporator disinfection
- Compressor repairs, pipe flushing and fault diagnosis
- Inspection and cleaning every 30,000 km or annually, whichever comes first
