How much does commercial duct cleaning cost?

It depends on the size of the system, the number of air handling units and the length of ductwork, how easy it is to get to, and how contaminated it is. We survey the system first and quote in writing. Our guide to commercial duct cleaning costs in Perth explains what drives the price.

Do you have to shut the system down to decontaminate it?

Most of our jobs are delivered with minimal disruption to operations. Where we can stage zones and isolate sections of the system, we do - and we sequence the works so the spaces your staff and tenants use stay available. Where a full shutdown is genuinely required, we'll tell you up-front and book it in around your operational windows (often overnight or during planned outages).

What standards do you work to?

AS/NZS 3666 (the Australian air-handling and water systems standard) and the relevant manufacturer specifications for each component we touch. Every job is sequenced to those standards, not a generic checklist.

How do I know the decontamination actually worked?

Three ways: visual before/after photo evidence per zone, optional swab and air sampling analysed by a NATA-accredited lab, and a written clearance report on completion. The clearance pack is auditable and can be handed straight to insurers, regulators or your own QA team.

How often should commercial ducts be cleaned?

Depends on the system, the environment and the contamination history. Most well-maintained commercial systems benefit from a full decontamination every 2-5 years, with annual visual inspections in between. We're happy to scope a recurring programme tailored to your asset.

Commercial duct cleaning and ventilation hygiene in Perth and WA

Restored to a verified clean baseline.

Commercial duct cleaning removes dust, debris and microbial growth from the air handling units, coils and ductwork that supply a building's air. Practical Maintenance Services (PMS) cleans ducts on commercial, industrial and government sites across Perth and the Pilbara, working to AS/NZS 3666 with negative-pressure extraction, HEPA filtration and before and after photos for every zone.

What's included in the scope

Every engagement is delivered to a documented standard. These are the inclusions you can expect to see itemised on your scope of works and reflected in the close-out pack.

The work on site

Pre-works visual survey and zone mapping
Negative-pressure containment and HEPA extraction
AHU, FCU, coil and condensate tray cleaning
Duct interior cleaning and antimicrobial treatment
Flexible duct replacement by licensed contractors where cleaning can't recover it

What you walk away with

Photo-documented before/after evidence per zone
Swab and air sampling on request, analysed by a NATA-accredited lab
Clearance report and certificate at close-out

Your HVAC tells you when it's overdue.

AS/NZS 3666 expects air-handling systems to be inspected and kept clean. Long before an audit picks it up, the system itself shows the signs - here's what they usually mean.

Book a system inspection

Your HVAC tells you when it's overdue.
What you're noticing	What it usually is
Musty smell when the system starts up	Microbial growth
Dust streaks at diffusers and vents	Duct loading
Tenant complaints, headaches, allergies	IAQ issue
Rising energy use, weaker airflow	Fouled coils

An inspection tells us which it is. We survey, grade the contamination per zone, and bring the system back to a verified baseline - with before/after evidence.
