Frankston is a true beachside suburb, and salt off the bay is tough on split-system condensers. FreshDuct cleans coils and corroded fins, deep-cleans indoor heads and treats mould, with photo proof.
Beachside home? Your outdoor unit is fighting salt every day — a clean fights back.
Frankston is where the bay beaches really open up, and homes from the foreshore back through the town centre and up into the hills all sit in genuine coastal air. That is wonderful for a summer swim and hard on a split-system air conditioner. The salt carried off the water settles on the outdoor condenser day and night, corroding its aluminium fins, filming the copper coil and rusting the cabinet from the outside in.
Frankston homes lean heavily on split systems — many are the main cooling and the winter heating for the house. That means long run hours, and a hard-working indoor head builds up the dust and condensation that feed black mould on the barrel fan and drum. Closer to the foreshore, the outdoor unit corrosion is faster; further up the hill it is gentler, but the salt still reaches you.
FreshDuct cleans Frankston split systems for the coastal conditions they live in. We wash and de-scale the condenser, comb corroded fins, deep-clean and sanitise the indoor head, and tell you honestly how the sea air is treating your unit — all documented with before and after photos.
The things we look at first on a Frankston split system — based on the local homes and conditions.
Frankston’s beachside position means strong, constant salt exposure on the outdoor unit. We clean the coil and fins and assess corrosion, which is the single biggest factor in how long a condenser lasts here.
Many Frankston homes cool in summer and heat in winter on the same split, so it runs nearly year-round. That constant duty builds grime on the indoor coil and fan — a yearly clean keeps it efficient and healthy.
Sea air carries moisture, and combined with long run times it makes the indoor head a prime spot for mould. We sanitise the fan, coil and drain to clear it and stop the musty smell returning quickly.

On the Frankston foreshore, an outdoor unit is corroding whether you can see it yet or not. The salt film on the coil makes the compressor labour, and eaten-away fins choke the airflow. We wash and de-scale the coil and straighten and clear the fins so the unit breathes and cools the way it should.
We will also tell you plainly if a heavily corroded unit is nearing the end of its life, so you can plan rather than be caught out on the first 38-degree day. No pressure, just an honest coastal assessment.

Because Frankston sits in strong coastal salt air, the outdoor condenser benefits from cleaning more often than an inland unit — often every 9 to 12 months, sooner if you are right on the foreshore. The indoor head should be deep-cleaned at least yearly, especially if the split also heats the home in winter.
