Frequently Asked Questions

  • What causes machinery air conditioning to fail?

    Common causes include low refrigerant levels, clogged filters, worn hoses, electrical issues and blocked condensers. Heavy equipment use often involves high dust, vibration and temperature changes, which can lead to loose connections or system strain. Without regular maintenance, these problems reduce airflow or cause complete failure. Frequent servicing helps catch these issues early, keeping the A/C system efficient, reliable and safe for the operator.

  • How often should I service heavy machinery air con systems?

    Most machinery A/C systems should be serviced at least once every 12 months, or more frequently if the machine is used daily or in dusty, humid or high-heat conditions. Regular servicing includes re-gassing, leak checks, filter replacements and compressor inspections. Staying on top of maintenance helps extend the system’s life, avoid major breakdowns and ensure consistent airflow and comfort for your operators.

  • Can I clean the A/C system myself, or should I use a technician?

    While some basic maintenance like filter cleaning can be done in-house, it’s best to use a technician for full servicing. Qualified professionals have the training and tools to handle refrigerant safely, diagnose faults accurately and access components without causing damage. DIY work can miss hidden issues, and improper repairs may lead to bigger problems. For reliability and compliance, a technician is the smarter choice.
