Car Air Conditioning Gladstone & Calliope | AU62626
Licensed automotive air-conditioning diagnosis, servicing, regassing and repairs for cars, 4WDs, utes, trucks, caravans and selected machinery.
Total Mobile Mechanical Services holds ARCtick authorisation number AU62626 for automotive refrigerant handling.
We support customers throughout Gladstone, Calliope and surrounding Central Queensland areas with workshop-based testing and suitable mobile support.
Air-Conditioning Diagnosis Before Regassing
Low refrigerant may be caused by leakage, but poor cooling can also involve the compressor, condenser, evaporator, expansion device, cooling fans, electrical controls or airflow through the cabin.
Diagnosis may include:
- Vent-temperature testing
- System-pressure assessment
- Compressor-operation checks
- Leak testing
- Condenser and cooling-fan inspection
- Blower-fan and cabin-airflow checks
- Electrical circuit and control-system testing
- Scan-tool checks where supported
Regassing alone will not repair a leaking or failed component. Testing helps determine the appropriate repair before refrigerant is added.
Automotive Air-Conditioning Regas
Where the system is suitable for regassing, the process may include refrigerant recovery, vacuum testing, evacuation and recharging with the specified refrigerant quantity.
Operating pressures, vent temperature and system performance are checked after charging. The exact process depends on the vehicle and system condition.
Air-Conditioning Component Repairs
We diagnose and repair faults involving:
- Compressors and compressor controls
- Condensers
- Evaporators
- TX valves and other expansion devices
- Receiver-driers and accumulators
- Refrigerant hoses, pipes, seals and fittings
- Pressure switches and sensors
- Blower motors, resistors and fan controls
- Blend-door and HVAC control faults
Parts are recommended after the fault and system condition have been assessed.
Car and 4WD Air Conditioning
We service air-conditioning systems in family cars, work utes, four-wheel drives, vans and light commercial vehicles.
For 4WDs used in dust, heat, towing or long-distance travel, we can also inspect cabin filters, condenser airflow, cooling-fan operation and related electrical systems.
General car and 4WD repairs are covered on our car and 4WD mechanic page.
Truck, Machinery and Agricultural Air Conditioning
Air-conditioning support is available for trucks, earthmoving equipment and agricultural machinery where the system, location and required repair are suitable for our equipment.
Services may include performance testing, electrical diagnosis, leak testing, component replacement and refrigerant servicing.
Learn more about our truck repairs, earthmoving support and agricultural machinery services.
Air-Conditioning and Auto Electrical Faults
Many air-conditioning faults are electrical. A compressor that does not engage may be affected by wiring, fuses, relays, pressure sensors, temperature sensors, fan controls or the vehicle’s control modules.
Our auto electrical and diagnostic capability allows these connected faults to be tested through the same business.
Signs Your Vehicle Air Conditioning Needs Attention
- Air is no longer cold
- Cooling is intermittent
- Cooling drops at idle
- Airflow from the vents is weak
- The compressor is noisy
- The system repeatedly loses performance after regassing
- There is an unusual smell from the vents
- Water is entering the cabin
