In cool, damp Healesville, reverse-cycle splits carry the winter heating and run for months on end. FreshDuct cleans coils, fans and condensers and clears mould, with photo proof.
Split is your main heater? Winter-long runs build mould — a clean keeps the air healthy.
Healesville sits in the heart of the Yarra Valley, ringed by forested hills and noticeably cooler and damper than suburban Melbourne. Here a reverse-cycle split system is rarely just for summer cooling — it is often the main source of winter heating, running long hours through the valley’s cold, wet months as well as cooling the home in summer. That heavy, near-year-round use changes what the unit needs.
Long winter runtime and valley humidity are the local issues. A split that runs for months as a heater draws damp valley air across its coil, and the moisture, combined with the dust and organic matter of a bush setting, gives black mould an ideal place to grow inside the head. The filter and coil clog steadily, cutting both the heating and cooling, and the outdoor unit collects leaf litter, pollen and bushfire-season ash and debris from the surrounding forest.
FreshDuct cleans Healesville split systems for this hard-working, year-round duty. 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 Healesville split system — based on the local homes and conditions.
In Healesville a reverse-cycle split often runs for months as the winter heater, not just a summer cooler. That long runtime builds grime and mould fast, so a yearly deep clean keeps both the heating and the air healthy.
The Yarra Valley’s cool, humid air and long run hours make the indoor head a prime spot for mould. We deep-clean and sanitise so the unit is not blowing spores and a musty smell into a home you heat with it.
Surrounded by forest, Healesville condensers collect leaf litter, pollen and bushfire-season ash that clog the fins. We clear the debris and wash the coil so the unit runs efficiently in both seasons.

A Healesville split works far harder than a city unit because it heats through a long, damp valley winter as well as cooling in summer. All those run hours, in humid bush air, mean mould and grime build up inside the head and the filter and coil clog quickly.
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 in both seasons. For a home that relies on its split to stay warm, a clean unit means healthier air and lower running costs all year.

Because it runs so many hours through a cool, damp Yarra Valley winter, moisture and dust build up inside the head and grow black mould, which causes the musty smell. Since you heat the home with it, that air is being recirculated. A deep clean and sanitise clears the mould and freshens the air.
Often, yes. A Healesville split typically runs long hours heating in winter as well as cooling in summer, in humid valley air, so grime and mould build up faster. A yearly deep clean is a sensible baseline, and heavy winter use or a bush setting can make a mid-year clean worthwhile.
