Frequently Asked Questions
Why is heavy HVAC preventative care so important?
Yes, we offer 24/7 mobile field support across Queensland. Our fully equipped vehicles can handle fault finding, air conditioning repairs, and machine rewiring directly on your mine site, quarry, or roadside breakdown.
Do you handle the compliance and registration?
In harsh Australian conditions, a failed cabin air conditioning system isn't just uncomfortable; it is a critical OH&S safety hazard that can immediately ground a machine. Routine preventative maintenance catches compressor wear and gas leaks early, keeping your operators safe and avoiding expensive, unplanned downtime.
Can you custom wire mine-spec vehicles?
Absolutely. We specialise in complete machine fit-outs, accessory installations, lighting plants, battery isolation switches, and custom control systems tailored strictly to meet specific mine-site compliance and safety requirements.
What diagnostic tools do you use?
Our technicians are equipped with modern, specialised diagnostic and programming software capable of interfacing with modern electronically controlled machinery and transport equipment across all major brands, ensuring accurate fault finding and efficient repairs.
