Altona sits between the beach and the western industrial belt, so its split condensers cop both bay salt and airborne grit. FreshDuct cleans coils, fins and indoor heads and treats mould, with photo proof.
Salt from the beach, grit from the west — both clog condensers, and a clean clears them.
Altona has an unusual double character: a quiet beachside suburb with a long swimming beach and foreshore, backed by the petrochemical and light-industrial belt that defines much of Melbourne’s inner west. That means a split-system condenser here contends with two things at once — the salt air rolling in off the bay, and the fine airborne grit that drifts across from the industrial areas and busy freight routes nearby.
The housing runs from post-war brick homes and beach cottages to newer estates and townhouses, and split systems are the common cooling. Out in this mixed air, the outdoor unit’s fins take salt corrosion from the bay and a film of industrial dust on top, so airflow drops and the coil struggles to shed heat. Inside, the heads run hard through summer and build the damp dust and mould that bring the stale start-up smell.
FreshDuct cleans Altona splits for these combined conditions. We wash the salt-and-grit-clogged condenser and comb the fins, deep-clean and sanitise the indoor head, clear the drain, and finish with before and after photos so you can see what came out.
The things we look at first on a Altona split system — based on the local homes and conditions.
With the beach close by, Altona condensers take salt that corrodes the aluminium fins and films the coil. We wash and comb the fins and check for corrosion before it costs the unit its efficiency and life.
Altona backs onto the western industrial belt and busy freight roads, so condensers also collect a fine film of grit that blocks the fins. Clearing it restores the airflow the unit needs to cool properly.
Coastal humidity and long summer run hours let mould take hold on the indoor coil and drum. We deep-clean and sanitise the fan and coil so the split blows clean air instead of a musty smell.

An Altona condenser has a harder job than most, taking salt off the bay and industrial grit off the western belt at the same time. Both cut the airflow across the coil, so the system runs hotter and longer for the same cool. We clear it all — fins combed, coil washed, debris removed.
Inside, we strip and clean the barrel fan and coil a filter rinse can never reach, then sanitise to clear mould at the source. You get a unit that cools faster, smells clean and uses less power on a hot beachside afternoon.
FreshDuct cleans split systems across Altona and the inner-west bayside 7 days a week. We regularly work neighbouring Williamstown, Point Cook, Werribee and Yarraville, so Altona and its beachside streets are part of our normal run.

Altona sits between the beach and the western industrial belt, so its outdoor condensers pick up both salt off the bay and fine grit from the industrial areas and freight roads. That combination films the coil and clogs the fins faster than salt or dust alone, so the outdoor unit benefits from more regular cleaning.
Yes. We wash and de-scale the coil to lift the salt film, comb the fins to restore airflow, and clear the industrial grit that settles on top. Then we deep-clean the indoor head and sanitise it, so both ends of the system are cleaned for the conditions Altona sits in.
