Frequently Asked Questions

  • What are common signs your machinery A/C system needs repair?

    Reduced airflow, warm air, unusual smells, loud fan noises or inconsistent cooling are all signs your A/C system may need attention. These issues can be caused by low refrigerant, blocked filters, worn components or electrical faults. Addressing them early can prevent full system failure and keep your machinery safe and comfortable for your operators during long shifts.

  • How often should heavy machinery A/C systems be serviced?

    Air conditioning systems in heavy machinery should typically be serviced every 12 months, or more often in dusty, humid or high-use environments. Servicing includes re-gassing, filter changes, leak checks and compressor inspection. Keeping on top of this maintenance improves cooling performance, extends the life of the system and ensures reliable operation when you need it most.

  • Can poor A/C performance affect machine operators?

    Yes – poor cabin airflow can lead to overheating, fatigue and loss of focus, especially in enclosed cabs during warm weather. Over time, this can affect operator safety, productivity and morale. A properly working A/C system helps maintain safe working conditions, supports WHS requirements and keeps your crew comfortable and alert throughout the day.
