Northcote’s period homes and newer apartments run wall-mounted and multi-head splits, often retrofitted into tight spaces. FreshDuct cleans coil, fan and condenser and treats mould, with photo proof.
Retrofitted split in a period home? We deep-clean the parts a filter rinse never reaches.
Northcote runs from the shops and bars of High Street out to the quiet period streets around Ruckers Hill, and its housing is a blend of Victorian and Edwardian homes, interwar houses, and a growing layer of apartments and townhouses. None of the older stock was built for air conditioning, so almost every split system here is a retrofit — a head bolted to an internal wall with the outdoor unit squeezed into a side passage, a rear courtyard or onto a back wall.
That retrofit reality shapes the cleaning. Outdoor condensers end up in cramped, low-airflow spots where they collect leaves and dust and run hot, while indoor heads work hard through the Northcote summer cooling rooms with high ceilings and big windows. The barrel fan and coil fill with the dust and condensation that grow black mould, and because the units are often an afterthought, they rarely get a proper clean.
FreshDuct cleans Northcote split systems thoroughly. We deep-clean and sanitise the indoor head, reach and wash the tucked-away outdoor unit, clear the drain, and finish with before and after photos so you can see what the retrofit had been hiding.
The things we look at first on a Northcote split system — based on the local homes and conditions.
Retrofitted Northcote condensers often sit in narrow side passages or rear courtyards with poor airflow. We reach and clean them properly, and clear the debris that builds up in those enclosed spots.
High-ceilinged period rooms make the indoor head run long and cold, and that condensation grows mould on the fan and drum. We strip, deep-clean and sanitise the parts a filter rinse can never reach.
Northcote’s newer apartments and townhouses often run multi-head systems. We clean each indoor head and the shared condenser so the whole home is fresh, not just one room.

A retrofitted split in a Northcote period home is rarely in an ideal position, so a real clean takes more than a quick look. We open up the indoor head, deep-clean the barrel fan and coil over a catch bag, and reach the outdoor unit wherever it was wedged when it was installed.
We clear the leaves and dust that collect around condensers in tight side passages, which is a common reason a Northcote unit runs hot and cools poorly. You get a system that works the way it should and air that is genuinely clean.
FreshDuct cleans split systems across Northcote and the inner north 7 days a week. We are regularly on units in neighbouring Fitzroy, Brunswick, Collingwood and Abbotsford, so Northcote and its borders are part of our everyday run.

Yes. Most Northcote splits are retrofits with the condenser in a tight side passage or rear courtyard. We reach and clean the coil and fins, clear the leaves and dust that collect in those enclosed spots, and deep-clean the indoor head as well.
Often it is a clogged coil and fan indoors and a dust-choked or poorly ventilated condenser outdoors, both common with retrofits in period homes. Cleaning both restores airflow and cooling, frequently making an under-performing unit feel almost new again.
