At the gateway to the Yarra Valley, Lilydale’s reverse-cycle splits carry the winter heating and run hard for months. FreshDuct cleans coils, fans and condensers and clears mould, with photo proof.
Heating with your split all winter? Long runs grow mould — a clean keeps the air healthy.
Lilydale sits at the gateway to the Yarra Valley, where Melbourne’s outer east gives way to the hills and vineyards. It is cooler and damper than the inner suburbs, and its mix of established homes and newer estates leans heavily on reverse-cycle split systems — not just for summer cooling but as the main winter heating, running long hours through the cold, wet months.
That year-round, heating-led duty is the key. A Lilydale split that runs for months as a heater pulls cool, damp air across its coil, and the moisture combined with household and outdoor dust gives black mould an easy place to grow inside the head. The filter and coil clog steadily, cutting both heating and cooling, and the outdoor unit collects leaf litter and pollen from the surrounding greenery and, in summer, bushfire-season debris.
FreshDuct cleans Lilydale split systems for this hard-working schedule. We deep-clean and sanitise the indoor head to clear mould, clear leaf litter and wash the outdoor unit, clear the filter and drain, and finish with before and after photos.
The things we look at first on a Lilydale split system — based on the local homes and conditions.
In Lilydale a reverse-cycle split is often the main heater, running long hours through a cold, damp winter. That runtime builds grime and mould fast, so a yearly deep clean keeps the heating and the air healthy.
Lilydale’s cooler, more humid climate and long run hours make the indoor head a prime spot for mould. We deep-clean and sanitise so the unit is not recirculating spores and a musty smell into a home you heat with it.
On the valley’s edge, Lilydale condensers collect leaf litter and pollen from the surrounding greenery. We clear the debris and wash the coil so the outdoor unit runs efficiently in both seasons.

A Lilydale split does double duty — heating the home through a long, damp valley-edge winter and cooling it in summer — so it runs far more hours than a typical city unit. All that runtime in cool, humid air builds mould and grime inside the head and clogs the filter and coil.
We deep-clean and sanitise the indoor unit to clear the mould, and clear the leaf litter and wash the outdoor unit so it runs efficiently year-round. For a home that leans on its split for warmth, a clean unit means healthier air and lower bills through both seasons.

A Lilydale split usually runs long hours heating through a cool, damp valley-edge winter as well as cooling in summer, so it clocks up far more run time in more humid air than a typical inner-suburb unit. That builds mould and grime faster, so it benefits from cleaning at least yearly, sometimes more.
Yes. The musty smell is mould that has grown on the coil and drum during long, damp winter run hours, and because you heat with the unit it is recirculating that air. We deep-clean and sanitise the indoor head to clear the mould at its source, which removes the smell and freshens the air.
