Perth winters are short but genuinely wet, and a ducted system that has sat idle since March pushes months of settled dust into the house on the first cold morning. FreshDuct cleans the whole system before you switch it on.
First heating start-up smelling of dust? That is the duct, and it is entirely fixable.
Perth’s heating season is compressed. The city takes 77.7 per cent of its 723.9 mm annual rainfall between May and September, and that is when ducted heating gets used — hard, for a few months, after sitting untouched through a long hot summer.
That idle stretch is the problem. Through summer, fine windblown sand off the Swan Coastal Plain and household dust settle inside supply runs, return boxes and the unit itself. Nothing disturbs them for months. Then on the first genuinely cold morning the system starts, the blower comes up to speed, and all of it is lifted at once and pushed into every room the ducting serves. That dusty first-start smell is not the unit burning off — it is the duct.
We clean ducted heating systems of both common types in Perth homes: reverse-cycle ducted systems running in heating mode, and gas ducted heating. The cleaning approach differs between them, particularly at the unit, and we work to whichever you actually have rather than applying one method to both.
What a Perth ducted heating system is dealing with by the time you switch it on.
The runs, the returns and the unit — because contamination moves between all three.
Fine sand and household dust accumulate in supply runs and return boxes through the months the system is off. We brush and air-sweep every run under negative-pressure extraction so it leaves the building, rather than being redistributed the moment the blower starts.
The return is where most contamination enters, and the filter is almost always overdue. We clean the return box and grille and tell you plainly what filter that system should be running — a cheap change that does more for air quality than most things people spend money on.
On a gas ducted system the blower and heat exchanger need cleaning; on a reverse-cycle ducted system it is the blower and the indoor coil. Either way, a clean duct fed by a dirty unit re-contaminates itself within weeks. We clean the unit internals as part of the job and photograph them.
Perth ducted systems commonly run through roof cavities, and older retrofits sometimes run under floors. Both expose the ducting to sand, vermin and damage. We inspect for crushed, damaged or disconnected flexible duct before cleaning, because cleaning a run that is open to the cavity achieves nothing.
Because Perth heating runs precisely during the wet months, a damp return, a roof leak above a duct run or a condensate issue can leave duct interiors humid enough to support growth. Where we find it, we show you and treat it properly rather than cleaning past it.
Restricted ducts and a loaded filter make the system work longer to reach temperature. We photograph the before and after condition inside the runs so any improvement is something you can see rather than something we assert.

We inspect and camera the runs, then brush and air-sweep each one under negative pressure, clean the return boxes and grilles, and clean the unit internals appropriate to your system type — blower and heat exchanger on gas ducted, blower and indoor coil on reverse-cycle ducted.
Timing is the practical advice we give most often on this service: book it in April or early May, before the first cold snap. Cleaning the system before its first run of the season means the dust never gets distributed in the first place, which is a materially better outcome than cleaning up after it has been pushed through every room in the house.
Book a Perth Heating CleanWe clean ducted heating systems across metropolitan Perth. Newer homes through the northern corridor around Joondalup, Wanneroo and Ellenbrook, and the southern corridor through Canning Vale, Baldivis and Rockingham, typically run reverse-cycle ducted systems with roof-space ducting and a straightforward layout.
Older housing and the Hills belt are different jobs. Retrofit ducting in character homes through Subiaco, Fremantle, Guildford and Bassendean often threads through unsealed roof spaces or under floors, with more bends, more damage and more sand ingress. We quote on the system you actually have rather than a flat rate per outlet.
The whole system cleaned and documented, ideally before the season starts.
We look inside the runs and identify the system type before quoting.
Furnishings covered and access points protected before work starts.
Rotary agitation under negative pressure, run by run.
Returns and grilles cleaned, and the correct filter specified.
Blower plus heat exchanger or indoor coil, matched to your system type.
Before and after images from inside the system, handed over on the day.

Ducted heating cleaning pairs naturally with these Perth services.
April or early May, before the first cold snap and before the system runs for the season. Perth heating is used through the wet months from May to September after sitting idle all summer, so cleaning beforehand means the accumulated dust never gets distributed through the house in the first place.
Because months of settled sand and dust inside the ductwork are lifted the moment the blower comes up to speed. People often assume it is the unit burning off dust, but the volume involved is in the ducts, the return box and the unit internals. A full system clean removes the reservoir rather than masking the smell.
Yes, and the approach differs at the unit. Gas ducted systems need the blower and heat exchanger cleaned; reverse-cycle ducted systems need the blower and indoor coil. The ductwork itself is cleaned the same way in both cases. We identify which system you have during inspection and work to it rather than applying one method to everything.
Every two to three years for most Perth homes. Bring it forward if the home has pets, if anyone has asthma or allergies, if there has been building work, or if the ducting runs through an unsealed roof space where sand ingress is heavier. We will tell you honestly what interval your system warrants after inspecting it.
Yes. The unit internals are part of a proper clean, because a clean duct fed by a dirty blower re-contaminates itself quickly. We clean the blower and the heat exchanger or indoor coil depending on your system, and photograph them along with the runs so you can see what was actually done.
Runs, returns and unit internals cleaned and photographed. Book before the season starts. Available 7 days.
