Thermal Systems, Cooling & A/C
Diagnostics-led support for A/C, high-voltage thermal management and cooling.
R1234yf and R134a A/C, electric compressor, HV battery cooling, auxiliary heater and HVAC communication diagnostics across modern conventional and EV/hybrid platforms.
Thermal Management, Cooling & A/C Systems
Diagnostics and repair for A/C, HV thermal management and cooling systems across modern platforms.
We diagnose, test and repair air conditioning, cooling and thermal management systems on conventional, electric and hybrid vehicles.
We check electrical control, refrigerant performance, temperatures and live system behaviour with professional diagnostic and test equipment.
We can help with:
- A/C system diagnostics and performance testing
- R1234yf and R134a A/C systems
- Refrigerant system diagnostics
- Electric A/C compressor diagnostics
- High Voltage electric A/C compressor oil inspection and contamination checks
- Cooling fan and control system diagnostics
- Climate control and HVAC diagnostics
- EV & Hybrid thermal management diagnostics
- High Voltage Auxiliary Heater diagnostics
- HV battery cooling system diagnostics
- Heat exchanger and chiller system diagnostics
- Cooling pump and circulation system diagnostics
- Temperature sensor and control module diagnostics
- Thermal efficiency and system performance analysis
- Electronic cooling system fault tracing
- HVAC communication and control-related faults
On many EVs and hybrids, the A/C system does more than cool the cabin. It also helps control battery and high-voltage component temperatures, so a fault can affect performance, charging and system safety.
Thermal systems are closely linked to the vehicle electronics, energy management and communication networks. A single warning can therefore involve several connected components or only appear under certain conditions.
We use live data and direct testing to prove the fault before recommending parts.
Our aim is to find the underlying cause, not simply clear a code or replace the first component named in a fault report.
Professional diagnostic platforms, specialist test equipment and practical experience help us reach an accurate answer efficiently.
These systems need to be tested on the vehicle, so the work is carried out at our Dukinfield workshop.
Use our online booking form to share the vehicle details, warning messages and symptoms before your visit.
We keep you updated on the findings, parts required and repair progress.
Book a thermal system diagnostic.
If the A/C is not cold, an HV thermal warning is showing or you have a coolant fault, book the vehicle in for proper testing.
