Machinery Air Conditioning

Cabin AC regassing, leak detection, repair and replacement for plant and heavy machinery mobile across the Illawarra.

Operator comfort that doesn't drop out at the worst time

A working cab AC isn’t a luxury it’s a safety and productivity item. We diagnose, regas, repair and rebuild cabin air conditioning systems on plant, heavy vehicles and machinery.

Heat-related fatigue is a real safety risk on open pit and civil sites. When a cab AC stops working, productivity drops within hours and operators start making mistakes. We treat AC failure like any other critical breakdown.

Our techs hold ARC RAC02 refrigerant handling licences and carry full regas, recovery, leak detection and pressure testing kit in every mobile unit.

What’s Covered

From a quick regas to a full system rebuild

REGAS

Refrigerant Regas & Recovery

Full evacuation and regas to manufacturer specs. R134a and R1234yf certified. Done on site, machine back to work same day.

DIAGNOSIS

Fault Diagnosis

Leak detection with electronic sniffers, UV dye and pressure tests. Compressor, condenser, evaporator and control diagnostics.

REPAIR

Component Repairs

Compressor replacement, condenser repair, evaporator service, expansion valves, drier replacement and full hose remake.

REBUILD

Full System Replacement

Where systems are beyond economical repair, we supply and fit complete replacement systems sized to the cabin and duty cycle.

SCHEDULED

Pre-Summer Service

Pre-season AC servicing for fleets. Catch the leaks before the heat hits and avoid the November scramble for compressor stock.

Why operators choose us for AC

Properly licensed. ARC RAC02 certified — refrigerant is handled, not just blown into the atmosphere.
Mobile in one visit. Recovery, vacuum, regas and leak test all done on site.
Mining-grade systems. We work with brands like Red Dot, Bergstrom and Webasto built for dusty cabs and long shifts.
Diagnosed properly. No "she'll regas again, mate". If it leaks, we find and fix the cause.
Operator safety first. Heat stress is a real hazard. We treat AC repairs with the urgency they deserve.

Our Approach

Heat isn't just uncomfortable, it's expensive

Cab temperatures in summer can hit 60°C inside an enclosed machine. That’s not a comfort question it’s a productivity, fatigue, and safety question.

Studies of plant operators in hot conditions consistently show drops in alertness, slower reaction times, and a higher rate of small mistakes (which become big mistakes around 50-tonne machines).

Getting AC right pays back faster than most operators expect. We size, fit, and maintain systems that actually move heat out of the cab, not just push warm air around.
