Air Conditioning Servicing & Repairs in Plymouth
At Plymouth Motor Company, we provide professional vehicle air conditioning servicing, regassing, diagnostics and repairs for all makes and models from our trusted independent garage in Plymouth.

A properly functioning air conditioning system does far more than simply keep your vehicle cool during warmer weather. Your air conditioning system also helps remove moisture from the cabin, improve visibility and maintain overall driving comfort throughout the year.

Proper Air Conditioning Leak Testing
If an air conditioning system is empty or not operating correctly, simply re-gassing the system without testing for leaks is often only a temporary solution.
At Plymouth Motor Company, we follow a structured diagnostic process to help identify faults correctly before recharging the system.

Our testing process can include:
  • Nitrogen Pressure Testing
  • Leak Detection Fluid Testing
  • Vacuum Testing
  • UV Dye Leak Detection
  • System Performance Checks


We first pressure test empty systems using nitrogen and leak detection fluid to check for refrigerant leaks throughout the system.
The system is then vacuum tested to ensure it can hold vacuum correctly before refrigerant is added.
Once confirmed, the system is recharged with the correct refrigerant and UV dye where appropriate to assist with further leak detection and long-term system monitoring.
This methodical approach helps identify faults correctly and reduces the risk of unnecessary repeat re-gassing or ongoing air conditioning problems.

Air Conditioning Diagnostics & Repairs
Modern vehicle air conditioning systems are becoming increasingly complex and often involve electrical controls, pressure sensors, control modules and multiple system components.
Our experienced technicians carry out in-depth air conditioning diagnostics to accurately identify faults rather than simply re-gassing systems unnecessarily.
We diagnose and repair a wide range of air conditioning faults including:
  • Poor Cooling Performance
  • Refrigerant Leaks
  • Compressor Faults
  • Pressure Sensor Faults
  • Electrical Faults
  • Condenser Faults
  • Climate Control Issues
  • System Pressure Problems
  • Air Conditioning Servicing

Over time, air conditioning systems naturally lose refrigerant gas, reducing system performance and efficiency.

Regular air conditioning servicing helps maintain:
  • Cabin Cooling Performance
  • System Efficiency
  • Demisting & Visibility
  • Compressor Protection
  • Overall System Reliability

We carry out both R134a and R1234yf air conditioning servicing using modern equipment and manufacturer-approved procedures.
