Why it Matters

In Singapore’s tropical climate, ACMV systems run year-round at high intensity. Ductwork that is damaged, poorly insulated, or leaking does not just affect comfort. It drives up energy costs, accelerates equipment wear, and can create serious indoor air quality problems. Here is why ductwork repair should be a priority for your facility:

Prevent Energy Waste

Prevent Energy Waste

Leaking or uninsulated ducts can account for 20 to 30% of conditioned air loss. Timely repairs ensure your cooling system delivers air where it is needed, not into ceiling voids.

Resolve Condensation Damage

Resolve Condensation Damage

Singapore's humidity causes condensation to form rapidly on degraded duct insulation. Left unaddressed, this leads to water damage on ceilings, walls, and adjacent building fabric.

Protect Indoor Air Quality

Damaged ductwork allows dust, mould, and contaminants to enter your air supply. This is a particular risk in healthcare, food manufacturing, and cleanroom environments.

BCA Green Mark Icon

Support BCA Green Mark Compliance

Well-maintained ductwork reduces the load on your AHUs and FCUs, preventing premature wear and extending the operational life of your entire HVAC system.

Energy Efficiency Icon

Energy Efficiency

Duct airtightness and insulation quality are scored criteria under BCA Green Mark 2021. Addressing duct deficiencies directly supports your building's energy performance rating.

Our Process

When you engage Aircond.Network for ductwork repair or ducting installation in Singapore, we follow a structured approach to ensure every job is completed to the highest standard.

1
Site Inspection and Assessment
We conduct a thorough on-site inspection to identify duct leaks, insulation failures, condensation sources, and structural damage across your duct network.
2
Diagnosis and Scope of Work
Our engineers analyse findings and provide a clear scope of repair or replacement works, along with recommendations to prevent recurrence.
3
Duct Repair or Installation
Our in-house technicians carry out all repair and installation works, including sealing, insulation restoration, section replacement, or new duct fabrication as required.
4
Duct Cleaning
Where required, internal duct surfaces are mechanically cleaned prior to resealing or reinsulating to ensure long-term performance and air quality.
5
Testing and Commissioning
On completion, we test airflow and system performance to confirm the duct system is operating correctly and meeting design specifications.
6
24/7 Support
For urgent duct failures, our team is available around the clock for emergency response.

List of Ductwork Services

Aircond.Network offers a full range of ducting services for commercial and industrial facilities in Singapore:

Condensation Issue Resolution
Condensation Issue Resolution

We repair duct insulation to prevent condensation and energy loss. We diagnose the root cause, whether inadequate insulation thickness, a failed vapour barrier, or incorrect duct routing, and carry out targeted repairs to prevent moisture from damaging your building.

Insulation Restoration
Insulation Restoration

We restore or replace insulation to maintain optimal temperature control. Using materials suited to Singapore's climate including closed-cell foam, fibreglass wrap, and pre-insulated ductboard, we eliminate thermal losses and reduce energy consumption.

Duct Repairs
Duct Repairs

Damaged ducts are repaired or replaced to restore structural integrity and performance. Our scope includes mastic sealing of leaking joints, sheet metal patching, and full section replacement for ducts that have corroded through or collapsed.

Duct Leak Detection
Duct Leak Detection

We conduct systematic inspections to locate cracks, gaps at joints, and failed sealant, then carry out appropriate remediation so conditioned air reaches its intended destination.



Duct Cleaning
Duct Cleaning

Internal duct surfaces are mechanically cleaned to remove accumulated dust, debris, and biological matter, particularly important in food manufacturing, pharmaceutical, and healthcare facilities.


New Duct Installation
New Duct Installation

We design and install new ducting systems for HVAC retrofits, tenancy fit-outs, and building upgrades. Our scope includes galvanised steel ductwork, flexible ductwork, pre-insulated ductboard, stainless steel ductwork, and fire-rated ductwork compliant with SCDF requirements.

Frequently Ask Questions

For most localised repairs, our teams can complete work within a single shift or overnight window. Larger replacement projects are scoped and scheduled around your operational requirements.

In many cases, partial system isolation allows work to proceed while adjacent zones remain operational. Our engineers will assess this during the site inspection.

For most commercial buildings, a duct inspection every two to three years is advisable. In high-hygiene environments such as healthcare, food manufacturing, and cleanrooms, annual inspection is recommended.

Yes. Improved duct airtightness and insulation directly contribute to ACMV system efficiency, which is a scored component under BCA Green Mark 2021.

We work with all common commercial duct types including galvanised steel, pre-insulated ductboard, flexible ductwork, stainless steel, and fire-rated duct systems.
