ACMV & Ductwork Engineering in Singapore

The engineering behind better airflow.

We install, modify, repair and test air-conditioning ductwork for commercial buildings, fit-outs and existing systems across Singapore.

The basics

What is ductwork?

Ductwork is the network of ducts that moves air through a building as part of its ACMV or HVAC system.

It carries cooled or ventilated air from the system to different spaces, while other ducts may return or exhaust air from the building.

When layouts or building requirements change, ductwork may need to be installed, extended, rerouted or relocated. Existing systems may also require repair, leakage rectification or airflow balancing.

We build it, modify it, repair it and verify how it performs.

What we do

Ductwork Services

From new installation and modification to repair, fabrication and airflow testing, we support ductwork through different stages of a commercial project.

New ductwork, extensions, rerouting and modifications for office fit-outs, renovations and commercial projects.

Why Ventix

Why Choose Ventix?

Ductwork-first expertise, clear coordination and practical execution from site assessment to handover.

Ductwork-First Expertise

We focus on duct installation, modification, repair and airflow performance rather than trying to cover every M&E trade.

New + Existing Systems

From new fit-outs to existing ductwork that needs rerouting, relocation or rectification, we work with both new and existing systems.

Clear Scope & Quotation

The required works, pricing and scope boundaries are defined clearly before execution.

One Accountable Contact

Where applicable, one project contact coordinates the work from site review through completion.

Measured, Not Assumed

Where testing is required, airflow is measured and adjusted against the project requirements rather than judged by appearance alone.

Documented Handover

Site records, photographs and testing documentation can be provided where required by the project scope.

Our process

How We Work

From site assessment to execution and handover, each project follows a clear process based on the actual site and scope.

Site Survey

We review the site, existing ductwork, drawings and project requirements.
Site review · Measurements · Photos where required

Assess & Recommend

We identify what needs to be installed, modified, repaired or tested and recommend the appropriate scope.
Proposed work scope

Quote

We prepare a quotation based on the agreed scope and assessed site requirements.
Defined scope & pricing

Coordinate

We coordinate site access, work hours, sequencing and relevant requirements with the project or building team.
Access · Programme · Site coordination

Execute

Our team carries out the agreed installation, modification, repair or rectification works.
Site execution & progress coordination

Test & Handover

Where required, airflow is tested and adjusted before the completed works are handed over with the relevant project records.

Common questions

Questions Before You Engage a Ductwork Contractor

A few practical answers about duct installation, modification, repair and testing before you arrange a site survey.

No. Ventix works on both new and existing ductwork, including installation, extension, rerouting, relocation, repair, rectification and reinstatement.

Yes. Existing ductwork may need to be rerouted, extended or relocated when partitions, rooms or tenant layouts change. The required work depends on the existing system and the new layout.

Yes. We can assess duct leakage, damaged sections, insulation-related issues and other existing ductwork problems, then recommend the required repair or rectification scope.

Testing, Adjusting & Balancing, or TAB, is the process of measuring airflow and making adjustments so the system performs according to the required project conditions.

Yes, subject to site conditions, building requirements, access arrangements and the agreed work schedule. The site requirements should be reviewed before the work programme is confirmed.

Where available, send us the project location, current issue or required work, site photos, drawings, approximate scope and required timeline. Our team can then review the next step.

Yes. Ventix also supports kitchen exhaust ductwork and selected fire-rated and smoke-control ductwork projects, depending on the project scope and technical requirements.
