Post-Sale Support
We are committed to supporting you well beyond installation. From system commissioning to long-term maintenance, MHIAA partners with you to ensure your HVAC investment continues to deliver performance and reliability.

Control Systems Support
Complex control systems demand specialist expertise to deliver optimal energy efficiency and system performance. MHIAA can work directly with your installer or engineer to ensure your control system is correctly configured and integrated. Our team is available to help fine-tune settings, troubleshoot issues, and maximise system control across single or multi-site installations.

Dedicated Service Network
MHIAA partners with a trusted national network of experienced service technicians who understand MHI commercial systems inside and out. Located across major metro and regional areas, our service network is equipped to provide timely support and maintenance services across the full MHI commercial range, helping reduce downtime and ensure your system runs as intended.

Local Service Requests
All service requests are managed via MHIAA’s Australian-based support channels. Whether it’s a warranty issue or a spare part enquiry, our local team will coordinate the full process, including technician dispatch, part allocation and job tracking—offering you a single point of contact from start to resolution.

Local Technical Support
MHIAA’s technical support team is based locally and provides direct phone and email support to installers, contractors, and engineers. Whether it’s troubleshooting advice or assistance with system configuration, our knowledgeable team is here to help resolve issues quickly. Support is available Monday to Friday during business hours.

Preventative Maintenance
To keep your system operating at peak performance, MHIAA can support preventative maintenance schedules through our service partners. Where ongoing servicing isn’t offered by your installer, MHIAA can assist in coordinating planned maintenance programs that ensure system longevity, reduce running costs, and help avoid unexpected breakdowns.
