Commercial air duct cleaning services to AS 3666 standards — improving air quality, system efficiency and compliance across Melbourne & Victoria.
Commercial air duct and HVAC cleaning is the professional removal of dust, debris, mould, bacteria and contaminants from your building's air handling and distribution systems — including supply ducts, return ducts, air handling units (AHUs), diffusers, grilles and coils.
In commercial kitchens, ducting carries not just air but also grease-laden vapours. Over time, grease, carbon and biological contaminants accumulate inside duct walls, creating fire hazards, reducing system efficiency, and circulating polluted air throughout your premises.
Video inspection of accessible duct runs to assess contamination levels and identify any structural issues before cleaning commences.
High-powered rotary brushing and compressed air agitation to dislodge accumulated deposits from duct walls.
Industrial HEPA-grade negative air machines capture dislodged contaminants — nothing is released back into your premises.
Cleaning of air handling unit internals including evaporator coils, drain pans and blower assemblies for maximum efficiency.
Removal, cleaning and reinstallation of all supply and return air grilles and diffusers.
Photographic and/or video documentation of conditions before and after the clean, with a written service report.
Unclean HVAC ductwork is a recognised source of Legionella, mould and other airborne pathogens — with significant legal consequences for building owners.
The primary Australian standard for HVAC maintenance is AS 3666, which covers both design (Part 1) and operations and maintenance (Part 2). Key requirements include:
In Victoria, the Public Health and Wellbeing Act 2008 places obligations on building owners and operators to maintain premises in a way that does not endanger public health. Contaminated HVAC systems that spread mould, bacteria or Legionella can trigger enforcement action from the Department of Health.
Under the Occupational Health and Safety Act 2004 (Vic), employers must provide a safe working environment. Poor indoor air quality from dirty duct systems constitutes a workplace hazard. WorkSafe Victoria can issue improvement notices and fines to businesses where HVAC maintenance is neglected.
Section J of the NCC mandates minimum energy efficiency standards for HVAC systems. Blocked or dirty ducts reduce system efficiency and can cause your building to fall below required performance thresholds — potentially affecting your building's energy rating and tenancy compliance.

We clean the heating, ventilation and air conditioning ductwork in commercial premises across Melbourne and Victoria. We work on commercial sites only and don't clean residential ducted heating. Our clients include:
Every building is quoted individually. The main factors are:
Tell us about your building in a quote request and we'll come back within 24 hours.
We clean commercial ductwork across all of metropolitan Melbourne — the CBD, inner suburbs and the northern, western, eastern and south-eastern suburbs — and throughout regional Victoria, including Geelong, Ballarat and Bendigo.

Sick Building Syndrome (SBS) describes symptoms such as headaches, fatigue and eye or throat irritation that ease when people leave the building. Poor ventilation and dirty air handling systems are commonly linked to it, which is why clean ductwork, coils and filters are part of good building maintenance.
Dust on HVAC coils reduces how well they transfer heat, and blocked ducts force fans to run harder and longer to hold set temperatures. Keeping coils and ductwork clean lets the system run as designed instead of working against a build-up.
Legionella bacteria thrive in stagnant water and biofilm, including inside cooling towers and air handling units. Regular cleaning and maintenance of these systems is a key part of keeping that risk under control.
No. Air duct cleaning covers your building's heating, ventilation and air conditioning (HVAC) system — supply and return ducts, air handling units, coils, grilles and diffusers. Kitchen exhaust ductwork is cleaned as part of a canopy & exhaust clean. If there's a smell through the building or staff are complaining about air quality, that's usually an HVAC issue.
Every 6 months for commercial kitchens, food manufacturing, hospitals and aged care; annually for offices, retail, restaurants, schools and hotels; and every 2 years for low-occupancy buildings and warehouses. AS 3666 requires air handling systems to be inspected at least every 12 months.
HVAC and duct cleaning is performed to AS 3666.2, with full documentation for your compliance records.
No. HEPA-grade negative air machines capture the contaminants dislodged during cleaning, so nothing is released back into your premises.
Photographic and/or video documentation of conditions before and after the clean, with a written service report.
