Built around multi-residential build demands

Victoria's apartment and multi-residential construction pipeline continues to grow, and Vic Air's own business mix has shifted with it, from 95/5 residential-to-commercial toward 75/25 as commercial and multi-res work increases. Multi-res builds carry constraints that standard residential ducting supply does not always account for.

High unit counts. Apartment towers need ducting supply at a scale and consistency that single-dwelling residential jobs do not, across dozens or hundreds of units.
Riser duct systems. Multi-storey buildings rely on vertical riser ducting to distribute air between floors, requiring careful transition and sizing work.
Apartment-by-apartment zoning. Each unit typically needs independent climate control, rather than a single system serving multiple apartments.
Tight floor-to-ceiling constraints. Modern apartment designs often leave limited ceiling cavity space, ruling out standard duct systems in some units.

Industries we serve

Multi-res ducting supply is informed by NCC 2022 Section J Energy Efficiency requirements, which shape zoning and system efficiency expectations for apartment developments.

Zoning for individual apartment control

Multi-res buildings need each apartment to run its own climate settings independently of neighbouring units. izone zoning solutions support individual apartment control, suiting the unit-by-unit requirements typical of apartment tower and multi-res builds.

Mini duct systems for constrained ceiling cavities

Where floor-to-ceiling height is tight, standard ducted systems are often difficult to fit. mini duct air conditioning systems suit apartments with constrained ceiling cavities, delivering ducted comfort without the depth a standard system needs.

In-house fabrication for riser and transition pieces

Riser ducts and floor transitions in apartment towers are rarely off-the-shelf. Our Keilor Park facility fabricates non-standard sheet metal ductwork, including riser and transition pieces, in-house rather than through third-party fabrication shops.

Frequently Asked Questions

Q1. Does Vic Air supply ducting for apartment towers, or only single-dwelling homes?

Vic Air supplies both. Our commercial team works with mechanical contractors on apartment towers and multi-residential developments, alongside our residential supply work.

Q2. How does zoning work across multiple apartments in one building?

iZone zoning allows each apartment to run independent climate settings, rather than one system controlling multiple units, which suits the unit-by-unit requirements of multi-res builds.

Q3. What if an apartment has very limited ceiling cavity space?

Compact Comfort mini duct systems are designed for constrained ceiling cavities and can deliver ducted-style comfort where standard duct systems will not fit.

Q4. Can Vic Air fabricate custom riser ducts for apartment towers?

Yes. Our in-house fabrication at Keilor Park handles riser ducts, transitions, and other non-standard pieces specific to multi-storey apartment construction.

Q4. Does Vic Air provide quotes at tender stage for multi-res projects?

Yes. Our estimation service supports contractors with accurate, fast quoting for apartment and multi-residential project tenders, working from drawings before construction begins.
