Professional A/C Regas, Diagnostics & Repairs in Gladstone & Calliope (AU62626)

Total Mobile Mechanical Services – Car, 4WD & Truck Air Conditioning Specialists

Many customers think automotive air conditioning specialists only work on trucks — but we do everything, including cars, 4WDs, utes, vans, SUVs, light commercial vehicles, heavy vehicles, trucks, plant machinery, agricultural equipment and fleet vehicles.

Total Mobile Mechanical Services provides full automotive air conditioning services at our fully equipped workshop at 6 Wright Road, Calliope.

Central Queensland’s heat, humidity, dust and towing conditions are brutal on A/C systems. We repair, maintain and upgrade systems so they stay cold, reliable and efficient — whether you're driving a family car, work ute, touring 4WD, delivery van or long-haul truck.

A/C Diagnostics – Cars, 4WDs, Trucks & Machinery

We perform full system diagnostics, not just a regas:

Vent temperature & performance testing
High/low pressure analysis
Leak detection and pressure decay testing
Compressor clutch operation
Control system, HVAC module & CANbus diagnostics
Fan speed, airflow & blend door testing
Evaporator temperature differential
Expansion valve & TX valve diagnosis
Condenser flow & heat rejection checks

We identify the real cause of poor cooling — not just “topping up gas” and hoping for the best.

A/C Leak Detection & System Integrity Assessment

We find leaks other workshops miss:

UV dye leak detection
Nitrogen pressure testing
Electronic leak detectors (sniffer test)
Hose, O-ring & fitting inspection
Evaporator leak detection
Condenser damage checks
Refrigerant contamination testing

If your A/C stops working after a regas, that means a leak was never repaired.
We fix it properly.

A/C Regas & Refrigerant Handling (AU62626 Licensed)

No regas is done without a system check first.

Our regas procedure includes:

Full refrigerant recovery
Vacuum & moisture removal (critical for component life)
Leak detection before recharge
Correct refrigerant charge by weight (not guesswork)
PAG/POE oil balance & top-up
UV dye addition if required
Vent temperature & pressure verification
Cabin performance testing
Auto climate control calibration (if needed)

We follow national ARCtick standards — ensuring long-term reliability.

Signs Your A/C Needs Attention

Warm air at idle
A/C works sometimes but not always
Clicking noises from compressor
Foggy or smelly vents
High engine load when A/C is on
Water leaking into cabin
A/C cuts in and out randomly
Low airflow from vents

Small A/C issues can quickly turn into expensive compressor failures — get it checked early.
