Frequently Asked Questions

  • Can a faulty A/C system impact operator performance?

    Absolutely. Poor or inconsistent air conditioning can lead to overheating, fatigue, dehydration and reduced concentration – all of which affect safety and productivity. In sealed cabs, temperatures can rise quickly without proper cooling. Over time, this discomfort can also increase stress and reduce morale. Keeping the A/C system in good condition supports better decision-making, focus and physical wellbeing for anyone operating plant machinery.

  • How long does a typical A/C service take on-site?

    A standard machinery air conditioning service generally takes 30 to 90 minutes, depending on what needs to be done. Simple re-gassing or filter replacements are faster, while system diagnostics, electrical checks or compressor repairs may take longer. We aim to complete most services in one visit. Our mobile vans are stocked to handle the majority of A/C issues right away, helping you avoid return calls or additional delays.

  • Is mobile air conditioning repair as reliable as workshop servicing?

    Yes – when carried out by trained professionals, mobile A/C servicing delivers the same high standard as workshop repairs. Our technicians use industry-grade tools, approved parts and follow proper testing and repair protocols. The added benefit of mobile servicing is reduced downtime – as there’s no need to transport your equipment off-site. It’s an efficient, flexible solution that keeps your machines in service – and your team on schedule.
