Thornbury’s period homes and new High Street apartments run splits retrofitted into tight spaces or shared across multi-head systems. FreshDuct cleans coil, fan and condenser, with photo proof.
Retrofit in a period home or a new-build multi-head? We deep-clean every part, mess-free.
Thornbury sits in the inner north between Northcote and Preston, along the High Street tram line and the Merri Creek. Its housing has two distinct sides: streets of Victorian and Edwardian cottages and interwar homes, and a fast-growing band of new apartments and townhouses rising along High Street and around the station. Both rely on split systems, and each brings its own cleaning challenge.
In the older cottages the split is almost always a retrofit — a head bolted to an internal wall with the outdoor unit wedged into a narrow side passage or rear courtyard, where it collects debris and runs hot in poor airflow. In the new apartments and townhouses it is more often a multi-head system, with several indoor heads drawing on one outdoor condenser on a balcony or shared roof. Either way, hard summer runs build the dust and mould on the coil and barrel fan that bring the stale start-up smell.
FreshDuct cleans Thornbury splits across both. We reach and clean the tucked-away condensers of the period homes and the multi-head systems of the new builds, deep-clean and sanitise each indoor head, and finish every job with before and after photos.
The things we look at first on a Thornbury split system — based on the local homes and conditions.
Thornbury cottage splits are usually retrofits, with the condenser squeezed into a narrow side passage or courtyard with poor airflow. We reach and clean them properly and clear the debris that builds up in those enclosed spots.
The new apartments and townhouses often run a multi-head system off one condenser. We clean each indoor head and the shared outdoor unit, so the whole home is fresh rather than just one room.
Whether in a cottage or a new flat, hard summer run hours build mould on the coil and drum. We deep-clean and sanitise the parts a filter rinse can never reach, clearing the mould and the musty smell.

Thornbury asks for two approaches. In a period cottage the retrofitted split is rarely in an ideal spot, so we open the head up, deep-clean the coil and fan over a catch bag, and reach the outdoor unit wherever it was wedged at install. In a new High Street build we clean every head on the multi-head system plus the shared condenser.
Either way we work tidily, protect floors and walls, and clear the drain. The result is a system that cools properly and air that is genuinely clean, whichever side of Thornbury’s housing you live in.
FreshDuct cleans split systems across Thornbury and the inner north 7 days a week. We regularly work neighbouring Northcote, Preston, Coburg and out toward Ivanhoe, so Thornbury and its borders are part of our everyday run.
