What Drives Duct Cleaning Prices in Melbourne
Number of registers
Each supply register represents a discrete duct run that must be accessed, cleaned, and reinstalled. More registers mean more work. Most Melbourne homes have 8 to 14 registers for standard ducted heating, but some larger homes have 16 to 20+. Confirm the register count when getting a quote — some operators charge per register above a base count.
System type
Gas heating: standard scope, standard price. Ducted reverse-cycle: adds fan coil cleaning and condensate service, typically $80 to $150 more than equivalent gas heating. Evaporative: adds pad inspection/replacement, water tray cleaning, and distribution system check, typically $100 to $170 more. Dual systems (gas plus evaporative in the same home): both scopes apply.
Roof space access
Homes where the roof space has restricted access — very low pitch, heavy insulation covering all duct runs, or complex layout — take longer to work in and may require additional time charges. Multi-storey Melbourne homes with ducted systems serving multiple levels are similarly more complex. Always describe your home type when getting a quote.
Condition of the system
A system that has not been cleaned for 5+ years may require additional time for heavily contaminated sections. Some operators charge a surcharge for heavily fouled systems; others include it in the standard price. Ask what happens if the system is found to be more contaminated than typical.
Inclusions
Confirm what is included in any quoted price: filter replacement (some include it, some charge separately — allow $20 to $60 for filter cost), sanitisation fogging (should be included in any quality service), camera inspection (typically an add-on at $80 to $150), and written condition report.
Red Flags in Melbourne Duct Cleaning Pricing
The $99 whole-house special
A professional duct cleaning service requires expensive equipment (negative pressure extraction machine, rotary brush system, HEPA-filtered extraction), a skilled technician, and 2 to 3 hours of labour. A $99 quote for a whole-house service cannot cover these costs — it indicates a service that is not using professional-grade equipment and is not delivering the negative pressure extraction and physical agitation that the cleaning requires.
Phone quotes without a register count
A reputable Melbourne duct cleaning company needs to know your home’s register count, system type, and home size to give an accurate quote. A company that gives a firm price without asking these questions is either using a flat-rate model regardless of complexity (which means large-home customers subsidise small-home customers, or vice versa) or is planning to add charges on the day.
Cash-only operators with no ABN
A registered Melbourne business will have an ABN, provide a tax invoice, and accept payment by card or bank transfer. A cash-only operator with no ABN cannot provide a warranty, has no verifiable business address, and offers no recourse if the work is inadequate.
Duct Cleaning Costs for Melbourne Rental Properties
Victorian residential rental regulations include a requirement for heater servicing every 2 years. While duct cleaning is not separately mandated as a specific line item, it is encompassed within the general duty to maintain heating systems in proper working order. Many Melbourne landlords and property managers include duct cleaning on the 2-year service cycle alongside the gas heater service.
For landlords comparing costs: the duct cleaning cost for a rental property is a legitimate property maintenance expense and is tax-deductible in the year it is incurred. A written invoice from a registered business is required for the deduction. See our guide on duct cleaning for Melbourne rental properties for the full obligations and timing guidance.
