Up in the cool Macedon Ranges, Gisborne’s reverse-cycle splits carry the winter heating and run for months. FreshDuct cleans coils, fans and condensers and clears mould, with photo proof.
Ranges home heated by a split? Long winter runs grow mould — a clean keeps the air healthy.
Gisborne sits in the Macedon Ranges on Melbourne’s cool north-western fringe, higher and colder than the city, with frosty winters and a semi-rural, treed setting. Its established homes and newer estates rely heavily on reverse-cycle split systems, and in this climate the split is often the main winter heater, running long hours for months on end as well as cooling through the summer.
That heating-led, year-round duty defines what a Gisborne split needs. Running for months in cool, damp ranges air, the unit draws moisture across its coil, and combined with household and rural dust that gives black mould a ready place to grow inside the head. The filter and coil clog steadily, cutting both heating and cooling, and the outdoor unit collects leaf litter, pollen and, in the dry season, dust and bushfire-zone debris from the surrounding bush and paddocks.
FreshDuct cleans Gisborne split systems for this demanding 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 Gisborne split system — based on the local homes and conditions.
In the cold Macedon Ranges, a Gisborne reverse-cycle split often runs for months as the main heater. That heavy runtime builds grime and mould fast, so a yearly deep clean keeps the heating and the air healthy.
Gisborne’s crisp, humid ranges 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.
In a semi-rural ranges setting, Gisborne condensers collect leaf litter, pollen and dry-season dust and debris. We clear it and wash the coil so the outdoor unit runs efficiently in both seasons.

A Gisborne split runs far harder than a city unit because it heats the home through a long, cold Macedon Ranges winter as well as cooling in summer. All those hours in cool, damp air build mould and grime inside the head and clog the filter and coil.
We deep-clean and sanitise the indoor unit to clear the mould, and clear the debris and wash the outdoor unit so it runs efficiently year-round. For a ranges home that leans on its split for warmth, a clean unit means healthier air and lower running costs through both seasons.

A Gisborne split usually runs long hours heating through a cold, damp Macedon Ranges winter as well as cooling in summer, so it clocks up far more run time in more humid air than a typical city unit. That builds mould and grime faster, so it benefits from a deep clean at least yearly.
Yes. That smell is mould that grows on the coil and drum during long, damp winter run hours, and since you heat the home 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.
