Frequently Asked Questions

  • How often should machinery air conditioning be serviced?

    Most machinery A/C systems should be serviced at least once a year, or more frequently in high-dust, high-heat or high-use conditions. Regular servicing typically includes re-gassing, cleaning or replacing filters, checking hoses and belts, testing pressure levels and inspecting the compressor unit. Keeping the system in good condition helps prevent operator fatigue, supports WHS compliance, and ensures reliable cooling even during the hottest workdays.

  • What are signs of a failing cab A/C?

    If your air conditioner is blowing warm air, has weak or inconsistent airflow, makes unusual noises, emits bad smells or shuts off unexpectedly, it’s likely due for repair. These symptoms may point to blocked filters, refrigerant leaks, worn seals, fan failure or compressor issues. Catching faults early not only prevents total breakdowns, but can also save you money on future repairs and keep your operator focused and safe.

  • Can air conditioning repairs be done on-site in Wollongong?

    Yes – on-site air conditioning repairs are a standard service for heavy machinery in the Wollongong region. Mobile technicians arrive at your worksite with all the tools, refrigerant and components needed to carry out servicing or repairs immediately. This reduces downtime, eliminates the need for transport logistics, and ensures that machinery stays available and operational without leaving the job.
