Reservoir is one of Melbourne’s largest suburbs, full of big-block family homes whose splits have often run a decade unchecked. FreshDuct cleans coils, fans and condensers, with photo proof.
Family split running for years unchecked? Long-neglected units cake up — a deep clean revives it.
Reservoir is one of the largest suburbs in Melbourne by population, a broad sweep of the northern suburbs filled with post-war brick and weatherboard family homes on generous blocks, threaded by Broadway, Spring Street and the Merri Creek. It is settled, family-oriented territory, and its sheer size means an enormous number of split systems — many of them long-serving units that have cooled the same bedrooms and living rooms for a decade or more.
The story across so much of Reservoir is the long-neglected unit. A split installed years ago tends to keep working just well enough that no one thinks to service it, and all the while dust packs into the indoor coil, filter and barrel fan and mould takes hold in the damp inner parts. The cooling fades so gradually it is written off as the unit ageing, and outside the condenser collects yard debris and loses the airflow it needs to shed heat.
FreshDuct cleans Reservoir splits back to health. We deep-clean and sanitise the long-neglected indoor head, clear the mould, wash the outdoor condenser, clear the filter and drain, and finish with before and after photos so you can see how much a decade of use had left behind.
The things we look at first on a Reservoir split system — based on the local homes and conditions.
Countless Reservoir splits have run for years untouched, so the coil, fan and filter are packed with dust. We deep-clean the head to clear it and bring back the airflow and cooling the unit has quietly lost.
Years of run time in an unserviced head grow black mould in the damp inner parts, bringing the musty start-up smell. We sanitise the fan and coil to clear the mould at its source, not just cover it.
Because the decline is so gradual, owners write it off as the unit ageing. A thorough clean of both ends often restores far more cooling than expected, making a tired Reservoir split feel close to new again.

A great many Reservoir splits have simply never been deep-cleaned. They keep limping along, cooling a little less each summer, until the bedroom unit runs most of the night and the room still is not comfortable. It is easy to assume the unit is just old and past it.
More often it is a decade of packed dust and mould choking the airflow. We strip both ends of the system, clear the grime and mould, and restore the cooling — and owners are regularly surprised how much better a long-neglected unit performs once it is properly cleaned.
FreshDuct cleans split systems across Reservoir and the northern suburbs 7 days a week. We regularly work neighbouring Preston, Thornbury, Bundoora and Coburg, so Reservoir and its many streets are part of our everyday run.

Usually worth cleaning first. In most long-serving Reservoir units the poor cooling is a decade of packed dust and mould choking the coil, fan and condenser rather than a mechanical fault. A thorough deep clean of both ends often restores far more cooling than owners expect, so it is well worth trying before considering replacement.
For most Reservoir family homes a professional deep clean every 12 months keeps the coil, fan and filter clear and the cooling strong. If the unit has gone years without one, the first clean makes the biggest difference, and homes with pets, allergies or heavy summer use benefit from every 6 to 9 months.
