Oakleigh’s post-war homes and station-precinct apartments run split systems hard through south-east summers. FreshDuct cleans coils, fans and condensers and clears mould, with photo proof.
Older home or new apartment? We deep-clean caked coils and multi-head units alike.
Oakleigh is a lively south-east suburb known for its Greek heritage, the Eaton Mall dining strip and a busy station precinct, with a housing mix of solid post-war brick homes on established streets and a growing layer of apartments and townhouses around the centre. Split systems do the cooling across both, and each type has its own maintenance story.
In the older homes, the splits are frequently long-serving units that have cooled the same rooms through many south-east summers with little more than the odd filter rinse, so the coil and barrel fan are caked with dust and mould has taken hold — hence the musty smell on start-up and the gradual loss of cooling. In the newer apartments and townhouses, multi-head systems run several rooms off shared condensers, and owners often clean one head while the others sit neglected.
FreshDuct cleans Oakleigh split systems across both. We deep-clean and sanitise caked older heads, clean every unit on apartment multi-head systems, wash the outdoor condensers, and finish with before and after photos.
The things we look at first on a Oakleigh split system — based on the local homes and conditions.
Long-serving Oakleigh splits build thick dust and mould on the coil and fan over years of use. We deep-clean and sanitise to clear it and restore the cooling and air quality the unit has lost.
Newer Oakleigh apartments and townhouses run multi-head systems. We clean every indoor head and the shared condenser so the whole home is fresh, not just one room.
Long, humid south-east runs grow mould on the coil and drum, bringing the musty smell on start-up. We deep-clean and sanitise to clear it at the source rather than mask it.

Oakleigh throws up two kinds of job: a caked, long-neglected split in a post-war home, and a multi-head system in a new apartment where only one head has ever been cleaned. Both leave part of the home under-cooled or smelling musty.
We deep-clean and sanitise the older heads to clear years of dust and mould, and on apartment systems we clean every head and the shared condenser. Either way the whole home ends up cooling well and smelling fresh.
FreshDuct cleans split systems across Oakleigh and the south-east 7 days a week. We regularly work neighbouring Chadstone, Clayton, Caulfield and Moorabbin, so Oakleigh and its surrounds are part of our normal run.

Usually, yes. In older Oakleigh homes the split has often gone years with only a filter rinse, so the coil and fan are caked with dust and mould. That causes the smell and the weak cooling, not a fault. A thorough deep clean and sanitise normally restores both, saving the cost of replacement.
Yes. Newer Oakleigh apartments and townhouses often run several indoor heads on one outdoor condenser. We deep-clean and sanitise each head and clean the shared condenser, so every room is fresh rather than just the one you first noticed a smell or weak cooling in.
