Automotive Air Conditioning – Cars, 4WDs, Trucks, Machinery & Heavy Vehicles

Total Mobile Mechanical Services provides professional automotive air conditioning servicing, diagnostics, repairs and regassing for cars, 4WDs, utes, vans, SUVs, light commercial vehicles, trucks, heavy vehicles, plant machinery, agricultural equipment and fleet vehicles across Gladstone, Calliope and Central Queensland. We operate from our fully equipped workshop at 6 Wright Road, Calliope and are fully licensed under the Australian Refrigeration Council (ARCtick Licence: AU62626) to legally and correctly handle refrigerant gas, diagnose faults, repair components and restore full cabin cooling performance. Central Queensland’s extreme heat, humidity, dust, towing conditions and heavy loads place enormous stress on vehicle A/C systems. We repair, maintain and upgrade air conditioning systems so they remain cold, reliable and efficient in all operating conditions.

We Service Air Conditioning on All Vehicle Types

• Cars & SUVs: Toyota, Mazda, Hyundai, Kia, Ford, Holden, Mitsubishi, Honda, Subaru and more

• 4WDs & Dual Cabs: LandCruiser, Prado, Hilux, Ranger, BT-50, D-MAX, Navara, Patrol, Everest, Triton

• Utes & Light Commercial: Tradie vehicles, service bodies, canopy fit-outs

• Trucks & Prime Movers: Kenworth, Isuzu, Fuso, Hino, Volvo, Scania, UD, Western Star

• Heavy Machinery & Equipment: Excavators, loaders, graders, rollers, dozers, tractors, farm machinery

• Fleets & Industrial Vehicles: Mining support fleets, civil construction, transport companies, government vehicles

If it has an air conditioning system — we service it.

Complete Automotive Air Conditioning Diagnostics – Not Just a Regas

We perform full system diagnostics to identify the real cause of poor cooling:

• Vent temperature & cooling performance testing

• High and low refrigerant pressure analysis

• Leak detection & pressure decay testing

• Compressor clutch engagement checks

• Control system, HVAC module & CANbus diagnostics

• Fan speed, airflow & blend door testing

• Evaporator temperature differential testing

• Expansion valve & TX valve diagnosis

• Condenser flow & heat rejection checks

We diagnose properly — not just “top up gas and hope for the best.”

A/C Leak Detection & System Integrity Testing

We locate refrigerant leaks that other workshops miss using:

• UV dye leak detection

• Nitrogen pressure testing

• Electronic leak detectors (sniffer testing)

• Hose, O-ring & fitting inspections

• Evaporator leak diagnosis

• Condenser corrosion & impact damage checks

• Refrigerant contamination testing

If your A/C stops working soon after a regas, a leak was never repaired. We fix the cause — not the symptom.

A/C Regas & Refrigerant Handling – AU62626 Licensed

No regas is performed without a full system inspection. Our precise regas process includes:

• Full refrigerant recovery

• Vacuum & moisture removal

• Leak detection before recharge

• Correct refrigerant charge by exact weight

• PAG / POE oil balancing & top-up

• UV dye addition if required

• Vent temperature & operating pressure verification

• Cabin performance validation

• Climate control calibration where required

All work is performed in accordance with national ARCtick standards for long-term reliability.

4WD Touring, Off-Road & Towing A/C Specialists

We specialise in high-load air conditioning performance for:

• A/C load testing while towing

• Upgraded condensers for 4WDs

• Dual and rear A/C system repairs

• Off-road airflow optimisation

• Cabin filter upgrades for dust protection

• A/C performance checks before major trips

If you tow, travel remotely or work in dust and heat, your A/C works harder — we make sure it stays reliable.

Truck, Heavy Vehicle & Machinery Air Conditioning

We provide full air conditioning services for:

• Line-haul trucks & prime movers

• Tippers & rigid trucks

• Agricultural tractors

Signs Your Automotive A/C Needs Attention

• Warm air at idle

• Intermittent cooling

• Clicking noises from the compressor

• Foggy or smelly vents

• High engine load when A/C is operating

• Water leaking into the cabin

• A/C cutting in and out

• Low airflow from vents

Small A/C issues can rapidly turn into major compressor failures — early diagnosis saves money.
