R134a Air Conditioning Re-Gas & Repair in Shepperton
At Walton Bridge Garage in Shepperton, we provide professional air conditioning re-gas, diagnostics and repair services for vehicles fitted with R134a refrigerant systems.
If your air conditioning is not blowing cold air, taking longer to demist, has developed unpleasant odours, or has stopped working completely, we can inspect and advise.
Regular air conditioning maintenance helps maintain cooling performance, hygiene and system reliability.
Important – Refrigerant Type
We currently service R134a air conditioning systems only.
Most vehicles manufactured up to approximately 2016 use R134a refrigerant. Many newer vehicles use R1234yf refrigerant, which requires different specialist equipment.
If you are unsure which system your vehicle uses, please contact us with your registration number and we will advise.
What Happens During an Air Conditioning Re-Gas?
During the recharge process we:
- Recover existing refrigerant from the system
- Carry out a pressure check to identify major leaks
- Re-gas the system with the correct quantity of R134a refrigerant
- Inject ultraviolet (UV) tracer dye free of charge
The UV dye helps us trace and identify smaller leaks if they develop later.
Please note: Minor leaks may not always be detected during the initial pressure test.
Air Conditioning Diagnostics, Leak Testing & Repairs
If your air conditioning system is not functioning, the first step is usually to carry out a re-gas service.
This is because the system must contain the correct refrigerant charge before component testing can be carried out accurately. If the system is empty, pressure switches and compressor operation cannot be assessed correctly.
Once the system has been recharged, we can then determine whether:
- The system is operating normally
- There is an active refrigerant leak
- Further component diagnostics are required
If your system repeatedly loses refrigerant, there is usually an underlying leak.
We can test and diagnose leaks using:
- Nitrogen pressure testing to safely pressurise the system and identify leaks
- Ultraviolet (UV) tracer dye to locate smaller or developing leaks
Nitrogen testing allows us to check system integrity without introducing refrigerant into a leaking system.
Where faults are identified, we can carry out repairs including:
- Pipe and hose replacement
- Condenser replacement
- Compressor fault investigation
- Pressure switch and sensor replacement
- Electrical diagnostics
We will always advise clearly whether a re-gas alone is appropriate or if repair is required.
Cabin Filter Replacement & Anti-Bacterial Cleanse
For best results, we recommend replacing the cabin (pollen) filter and carrying out an anti-bacterial air conditioning cleanse at the same time as your re-gas.
The cabin filter traps dust, pollen and airborne particles and can restrict airflow over time.
An anti-bacterial treatment helps to:
- Eliminate odour-causing bacteria
- Improve air quality inside the vehicle
- Reduce musty smells from vents
- Support a healthier cabin environment
Refreshing refrigerant without addressing airflow or hygiene may not fully resolve cooling or odour issues.
R134a Air Conditioning Re-Gas Pricing
Up to 500g of refrigerant – £65 including VAT
Over 500g of refrigerant – £85 including VAT
Pricing reflects current R134a refrigerant supply costs.
When Should You Re-Gas Your Air Conditioning?
- Air is no longer blowing cold
- Windows take longer to demist
- Unpleasant smells from vents
- System has not been serviced in over 2 years
Air conditioning systems naturally lose refrigerant over time, reducing efficiency and increasing strain on the compressor.
