Frequently Asked Questions

  • How often should machinery air conditioning be serviced?

    Most machinery air conditioning systems should be serviced at least once a year, or more often for high-use machines or those working in dusty or hot environments. Regular servicing includes checking refrigerant levels, inspecting hoses and belts, replacing filters and testing airflow. Preventative maintenance helps reduce operator fatigue, prevent system failure and ensure compliance with site safety expectations.

  • What are the signs of a faulty A/C system in machinery?

    Common signs include weak airflow, warm air instead of cold, unpleasant smells, loud noises when the fan is running, or the system cutting in and out. These symptoms may indicate refrigerant leaks, clogged filters, blocked condensers or electrical faults. It’s best to have the system checked promptly to avoid full breakdowns and maintain comfort and visibility for the operator.

  • Can you re-gas machinery air conditioning on-site?

    Yes – mobile re-gassing is a standard part of most air conditioning repairs for plant and heavy machinery. Technicians carry refrigerant and equipment to assess and refill your system on location. In addition to re-gassing, they often inspect for leaks, pressure issues or worn-out components to ensure the system performs reliably and safely under load.
