Design to Delivery

Your Commercial Mechanical Partner

Built on a foundation of teamwork, reliability, and integrity, we deliver service that consistently exceeds expectations

At Project Air Melbourne, we specialise in delivering high-performance HVAC and mechanical systems for commercial and multi-residential projects across Greater Melbourne. We’re not just a subcontractor—we’re a project partner who brings structure, speed, and certainty to your build.

Led by industry operator Steve Dumigan, our team combines deep technical expertise with a practical, solutions-driven mindset. We understand the pressures of construction and deliver systems that perform—on-site, on-budget, and on time.

We collaborate with builders, developers, and consultants to deliver fully integrated mechanical packages that meet compliance, performance, and energy efficiency targets—while supporting streamlined delivery from rough-in to commissioning.

Our Services

Whether we’re engaged from early design or brought in to execute and commission, our clients value our clear communication, tight coordination, and sharp execution. We deliver mechanical solutions that work—first time, every time.

Design & Construct (D&C) HVAC Solutions

We partner with builders and consultants to design mechanical systems tailored to project-specific performance, compliance, and budget goals. We handle documentation, coordination, and construction through to commissioning, for apartments, mixed-use developments, schools, public infrastructure, and commercial tenancies.

Controls & Automation

We integrate building management systems (BMS) and standalone controls to deliver energy efficiency, better occupant comfort, and system performance insights.

Mechanical Installation

We supply and install full mechanical services including:

Air conditioning systems (VRV/VRF, split, ducted, packaged units)
Ventilation systems (toilets, car parks, stair pressurisation, kitchen exhaust)
Ductwork fabrication and installation
Chilled and heating water pipework

Testing, commissioning & balancing

We ensure your systems perform as designed. We conduct airflow and hydronic balancing, generate compliance reports, and liaise with consultants for sign-off.

Service & Maintenance

We offer preventative maintenance and breakdown response for commercial HVAC systems. Our maintenance plans extend asset life and reduce downtime.

Upgrades & Replacement works

We manage staged upgrade works in operational environments, such as schools, retail, and public buildings. Services include system replacement, asset lifecycle upgrades, and plant room refurbishments.

Lifecycle Support including warranty servicing, system upgrades, and preventative maintenance contracts.
