What Is Duct Installation & Modification?

Duct installation is the process of installing the ductwork that distributes or removes air as part of a building’s ACMV or HVAC system.

Duct modification involves changing existing duct routes when a building layout, tenancy or operational requirement changes. This may include extending, rerouting, relocating or replacing sections of existing ductwork.

New space? We build the ductwork. Layout changed? We modify what is already there.

Ductwork that is damaged or leaking rather than changed is covered by duct repair, leakage & rectification. Moves, handovers and layout changes are covered by duct reinstatement & relocation, and the sections themselves can be supplied through duct fabrication.

Common requirements

When Is Duct Installation or Modification Needed?

New Office or Commercial Fit-Out

Install new ductwork to support the planned layout, rooms and air distribution requirements.

Layout Changes & Renovation

Existing duct routes may need to be extended, rerouted or relocated when partitions and room layouts change.

Expansion or Reconfiguration

Modify existing ductwork when a tenant expands into additional space or changes how an existing area is used.

Reinstatement & Relocation

Remove, relocate or reinstate ductwork when tenants move, spaces are handed back or existing services need to be reconfigured.
Service scope

How it works

Our Duct Installation & Modification Process

Review the Site & Drawings

We review the proposed layout, existing system and relevant project requirements.

Confirm the Required Changes

Identify the new duct routes, extensions, rerouting or relocation works required for the project.

Coordinate & Install

Coordinate access and work sequencing before carrying out the agreed duct installation or modification works.

Check & Handover

The completed works are reviewed and, where required, airflow testing or balancing can be carried out before handover.
Why Ventix

Ductwork-First Expertise for New and Existing Systems

New + Existing Ductwork

We work with both new installations and existing systems that need extensions, rerouting or relocation.

Practical Site Coordination

Ductwork is coordinated around the actual layout, access and project requirements rather than treated as an isolated trade.

Clear Scope

The required works and project boundaries are defined clearly before execution.

Testing Available Where Required

Airflow testing, adjusting and balancing can be included where it forms part of the project requirement.
Common questions

Duct Installation & Modification FAQs

Duct installation involves installing ductwork that carries air through a building as part of its ACMV or HVAC system. The duct layout is planned according to the building, equipment and spaces that need to be served.

Ductwork may need modification when an office or commercial layout changes, new rooms are added, tenants expand, air outlets move or existing duct routes conflict with new construction works.

In many projects, existing ductwork can be extended to serve additional areas, subject to the existing system, airflow requirements and site conditions.

Yes. Duct routes can be reviewed and modified when office partitions, ceilings or layouts change. The required scope should be assessed together with the existing ACMV system and renovation plans.

Yes. Ventix provides duct installation and modification for office fit-outs, including new duct routes, extensions, rerouting and relocation based on the project requirements.

Testing, Adjusting & Balancing (TAB) can be carried out where required to measure and adjust airflow before project handover.
