Commercial Mechanical Services
Engineered for performance,
delivered with certainty.
Air Theory designs commercial mechanical systems that protect your design intent, satisfy the NCC and Australian Standards, and hand over exactly as specified. We join early, make ambition buildable, and stay through commissioning — no grey zones at the end.

Serving every part of the project team.
Commercial projects involve multiple stakeholders — each with different priorities. Air Theory works across the entire project team, aligning mechanical outcomes with what each party needs to succeed.
Developers & Asset Owners
Performance-led systems that are approval-ready, predictable on budget, and tight on programme — delivered exactly as specified.
Architects & Building Designers
Systems that protect design intent, meet code, run quietly, keep IAQ clean, and arrive fully coordination-ready.
Builders & Project Managers
Scope-tight, decision-ready mechanical packages that are QA-driven, variation-resistant, and straightforward to install.
Facility Managers & Operators
Systems designed for real-world operation — efficient, maintainable, well-documented, and tuned for maximum uptime.
Commercial Tenants & Fit-Outs
Fit-out services that connect cleanly to base-build, verify comfort, manage acoustics, and hand over ready to operate.
Stage 01
Connect
Discovery & Advisory
We start by getting the fundamentals right — clarifying project intent, identifying risks, and mapping the compliance pathway before design begins. This is where budgets get protected and scope gets defined.
- Rapid discovery and risk scan
- Heat load calculations (right-sizing from the start)
- BCA alternative solutions and performance pathways
- Section J energy strategy and documentation
Stage 02
Concept
Options & Strategy
We model the right system types for your project, present the trade-offs clearly, and agree on the best approach before documentation begins.
- VRF/VRV — air and water-cooled systems
- Variable Air Volume (VAV) — smart zone control
- Central plant — chilled, heating & condenser-water
- Heat pumps & heat recovery systems
- Concept packs with budget ranges & zoning strategies
Stage 03
Consult
Design & Documentation
Agreed strategies become fully coordinated, buildable documentation — checked against code, coordinated with other services, and ready for construction without ambiguity.
- Coordination-ready drawings, schedules & specifications
- Mechanical ventilation to AS1668.1 & AS1668.2
- Exhaust systems (toilet, kitchen, amenities, car parks)
- Controls narratives, BMS sequences & point schedules
- Design and installation certification
Stage 04
Contract
Delivery with AT-Certified Teams
We lead delivery as your D&C contractor or provide independent client-side governance — either way, structured quality assurance, clear accountability, and no scope drift on site.
- D&C HVAC contractor leadership or client-side governance
- Central plant, VRF/VRV, VAV and A/C procurement & oversight
- BMS & central controls installation
- QA gates, shop drawing reviews, variation protocols
Stage 05
Commission
Test, Balance, Verify & Sign-Off
We test, balance, and verify every system against the design intent — so performance is confirmed before the building is occupied, not after complaints start coming in.
- Commissioning plans and witnessed testing
- TAB (test & balance) and system tuning
- BMS graphics, trend logs & integration verification
- On-site training for building operators
Stage 06
Completion & Aftercare
Digital Handover & Aftercare
A thorough close-out means the building operator has everything they need — and the system keeps performing long after handover.
- Digital as-builts, O&M manuals & warranties
- Seasonal tuning and post-occupancy performance checks
- Fire damper rectification
- Ventilation and Section J compliance upgrades
- Heat-pump conversions & retrofits for energy savings
