How commercial duct and HVAC work is priced in Melbourne — quoted per site after assessment, what drives the cost, and how scheduling works around your operations.
8 min read FreshDuct Melbourne Melbourne, Victoria
Commercial duct and HVAC work is quoted per site rather than at a fixed price — because the scope genuinely varies from building to building, and an honest, accurate quote requires assessing the actual systems. This guide explains what drives the cost, why we work on an enquiry basis, and how scheduling works. FreshDuct provides clear, fixed quotes for Melbourne commercial and strata buildings after a site assessment.

Commercial duct and HVAC work is quoted per site, not at a fixed price, because several factors drive the scope — system size and complexity, access, the level of contamination, compliance requirements and how often the work recurs. A site assessment turns these into a clear, fixed quote.
Why Commercial Work Is Quoted Per Site
Unlike a standard residential job, commercial HVAC work has no typical size — a small office tenancy, a multi-floor building, a shopping centre and an industrial site are entirely different jobs with entirely different scopes. The systems, their size and complexity, the access, the contamination level and the compliance requirements all vary enormously. A single fixed price could not honestly represent that range. So commercial work is quoted per site: we assess the building and give you a fixed quote for your specific situation, which is the only accurate way to price it.
What Drives the Cost
Several factors define the scope and therefore the cost of commercial HVAC work: the size and complexity of the systems; the number of outlets, fans or units; access (easy or difficult, occupied or empty, height and confined spaces); the level of contamination or grease; compliance requirements such as AS 1851 work and certification; and whether the work is one-off or part of an ongoing program. We assess all of these during a site assessment and reflect them in a clear, fixed quote — so you know exactly what you are paying for and why.
Our Enquiry-Based Approach
We work on an enquiry basis for commercial work because it is the honest and accurate approach. A published headline price would either over-quote simple jobs or under-represent complex ones, and would not reflect your building. Instead, we assess the building, scope the work precisely, and provide a fixed quote you can rely on and budget against. There are no surprises — the quote reflects the actual work your building needs. This is how we keep commercial pricing fair and accurate.
Programs vs One-Off
For buildings with recurring needs, an ongoing maintenance program is usually more cost-effective than one-off jobs: planned work is more efficient than reactive call-outs, regular maintenance prevents costly breakdowns, clean systems use less energy, and costs become predictable and budgetable. For owners corporations and facility managers, a program turns variable maintenance into a planned line item. We can quote both a one-off job and an ongoing program so you can compare and choose. See our maintenance contracts guide.
Scheduling Around Your Operations
Commercial work is scheduled around your operations — after-hours, overnight, weekends, during quiet periods or shutdowns — so trading, staff or occupants are not disrupted. We coordinate access and any site requirements with your facility or building manager, and sequence the work to keep the building running. For ongoing programs, we set a schedule that fits your operations year-round. Scheduling is planned with you as part of the quote.
Getting a Quote
It starts with a site assessment, which is the step that lets us quote accurately. We review the building’s systems, access and requirements, then provide a clear scope and fixed quote — for a one-off job, an ongoing program, or both so you can compare. Call 0431 918 137 or request a site assessment and we’ll arrange a time that suits your operations.
Frequently Asked Questions
How much does commercial duct and HVAC cleaning cost in Melbourne?
Commercial work is quoted per site rather than at a fixed price, because the scope varies so much from building to building — system size and complexity, number of outlets, access, contamination level, compliance requirements and frequency all affect the work. A small tenancy and a multi-floor building are completely different jobs. Rather than a misleading headline figure, we assess the building and provide a clear scope and fixed quote for your specific situation. A site assessment is the only accurate way to price commercial work.
Why don’t you publish fixed commercial prices?
Because a fixed price for commercial work would be misleading — the scope is genuinely site-specific, and a number that fits one building would be wrong for the next. Publishing a headline figure would either over-quote simple jobs or under-represent complex ones, neither of which serves you. Instead we assess the building, scope the work precisely, and give you a fixed quote you can rely on. This is the honest and accurate way to price work that varies as much as commercial HVAC does.
What factors affect the cost of commercial HVAC work?
Several: the size and complexity of the systems (a large multi-floor air-handling system versus a small tenancy); the number of outlets, fans or units; access (easy versus difficult, occupied versus empty, height and confined spaces); the level of contamination or grease; compliance requirements (AS 1851 work, certification); and whether it is one-off or part of an ongoing program. We assess these during a site assessment and reflect them in a clear, fixed quote. See our commercial duct cleaning guide.
Is an ongoing program cheaper than one-off jobs?
Usually, yes — for buildings with recurring needs. Planned, scheduled work is more efficient to deliver than reactive call-outs, regular maintenance prevents the costly breakdowns and major repairs that neglect causes, clean systems run more efficiently and use less energy, and you get predictable, budgetable costs. For owners corporations and facility managers especially, a program turns variable maintenance into a planned line item. We can quote both a one-off job and an ongoing program so you can compare. See our maintenance contracts guide.
How quickly can you provide a commercial quote?
After a site assessment we provide a clear scope and fixed quote promptly. For straightforward buildings the assessment and quote can be quick; for larger or more complex sites it takes a little longer to scope properly. Either way, the assessment is the step that lets us quote accurately. Call 0431 918 137 or request a site assessment and we’ll arrange a time that suits your operations.
