Australia's Trusted HVAC Parts Supplier

Air Junction is an Australian-owned supplier of quality HVAC components, built to support the people who keep buildings comfortable — from solo contractors running their own van to large installation crews managing multi-site projects.

Who We Are

We supply the full range of air distribution and ventilation components that Australian HVAC installers rely on every day. Our product range covers grilles, diffusers, dampers, ducting, and accessories — all sourced and stocked with Australian installations and building standards in mind.

Whether you're fitting out a single residential unit or coordinating a large commercial project, we have the parts you need, ready to go.

Our Commitment to Quality

We believe the quality of your installation is only as good as the components behind it. That's why we stock premium quality products selected for durability, performance, and compliance with Australian standards. Every product in our range is chosen because we'd trust it in our own installations — not just because it's available.

What We Supply

• Grilles & Diffusers — Supply and return air grilles, linear slot diffusers, and ceiling diffusers for residential and commercial applications
• Dampers — Volume control and motorised dampers for precise airflow management and compliance
• Ducting & Fittings — Flexible and rigid ducting, bends, reducers, and connectors to complete any installation
• Accessories — Brackets, hangers, insulation, and finishing components that make a job complete
• Made-to-Order Sheet Metal — Custom fabricated components for non-standard applications and bespoke projects

Built for Australian Installations

Every product we stock is selected with Australian building standards and installation requirements in mind. We understand the compliance expectations that come with HVAC work in Australia, and we stock products that meet them. If you have a specific compliance question, get in touch and we'll help you find the right component.

How We Fulfil Orders

We dispatch from our central Australian hub, with fast turnaround on most stocked items. Most orders are dispatched within 1–2 business days. We ship Australia-wide to all states and territories, including regional and remote locations. Local pickup is also available for customers who prefer to collect in person.
