Boroondara heritage studies cover Surrey Hills residential precincts, confirming the importance of established streetscapes and building fabric. Extensions and rebuilt areas introduce new insulation, glazing and roof forms.
Compact AirSmart ducts may help cross these transitions. Separate zones can support different usage and loads, subject to a balanced system design.
The junction between old and new construction is often the key AirSmart design point. Beams, roof steps and changes in ceiling height can block a direct route, so the mechanical plan should be checked with the structural and architectural sections before work begins.
The two areas may also behave differently. Retained rooms can have more air leakage, while a new glazed extension may experience sharper solar loads. Oz Air Group uses separate room calculations and practical zone boundaries to address those differences.

Distribution can be planned across construction zones with different cavity conditions.
Restrained outlets reduce visual impact in retained bedrooms and formal spaces.
Glazed family areas can receive capacity and zoning suited to their exposure.
AirSmart treats particulates, microorganisms, VOCs and odours through three integrated stages.
Early mechanical input helps avoid clashes with beams, skylights, lighting and cabinetry.
Tell us whether this is a new build, renovation or upgrade and share any plans you have. We’ll contact you about the installation requirements and a tailored quote.
AirSmart states that IES can be designed to integrate with technologies such as solar, hydronic heat pumps and geothermal systems. It also describes inverter-driven performance as part of its system approach.
The appropriate heating and cooling plant depends on the building, existing services, project design and selected equipment. If you are planning electrification or have an existing energy system, tell us early so compatibility can be considered. Any projected savings need a project-specific assessment.
Oz Air Group brings Melbourne experienceand a practical renovation mindset to Surrey Hills projects. We discussconstraints before quoting, coordinate with the building team and use licensedinstallers to complete and commission the system.
Explore AirSmart for renovations and architectural homes or compare it with traditional ducted air conditioning.
Send Oz Air Group your existing and proposed floor plans. We can assess the transition between the retained house and extension and recommend an AirSmart approach grounded in the build.
