Our Services
HVAC Commissioning
HVAC commissioning is the core of what we do. We take responsibility for making sure every mechanical system in your building is not just installed — but fully tested, verified, and performing exactly to its design intent before handover.
Functional Testing & Verification
Functional testing proves that every system does exactly what it was designed to do — under real operating conditions. We test every component, sequence, and safety function before your building is handed over to the client.
Pre-Commissioning Checks
Getting commissioning right starts well before the first system is switched on. Our pre-commissioning checks identify installation issues, incomplete work, and potential faults early — saving time and avoiding costly delays during the commissioning programme.
System Troubleshooting & Fault Finding
When systems aren’t performing the way they should — whether during construction, at handover, or after occupancy — we get to the root of the problem fast. We don’t just produce a report. We find the fault, explain what caused it, and give you practical recommendations to fix it.
Design & Installation Reviews
Catching problems on paper is far cheaper than fixing them on site. We review HVAC designs and installation drawings from a commissioning perspective — providing practical, buildable feedback that helps avoid coordination issues, rework, and programme delays.
System Optimisation & Tuning
Buildings change over time — occupancy patterns shift, tenancies change, and systems that worked well at handover can drift out of balance. We provide post-occupancy optimisation and tuning to make sure your HVAC systems continue to perform at their best long after the project is complete.
Building Code Compliance
Every commissioning project we deliver is aligned with New Zealand Building Code requirements and relevant industry standards. We make sure your project isn’t just performing well — but fully compliant and properly documented for regulatory sign-off.
Commissioning Reports
Every project we commission is fully documented with clear, accurate, and professional commissioning reports. Our reports are written to be understood — not just filed away. They give your team, your client, and your certifier exactly what they need for handover and sign-off.
Operation & Maintenance Manuals
A good O&M manual is one your team can actually use. We produce clear, well-structured Operation and Maintenance manuals that give facility managers and building owners everything they need to operate, maintain, and get the best out of their building’s mechanical systems.
