Down on the bay in Frankston, older housing and hard-worked splits meet the same salt air that corrodes coastal condensers. FreshDuct diagnoses the real fault — corroded coil, failed fan motor or a refrigerant leak — and repairs it properly, all major brands.
A coastal unit that once coped and now struggles often has both corrosion and a worn part.
Frankston sits at the southern end of Port Phillip Bay, a large suburb of established, often older housing where split systems do the bulk of the cooling. Being on the coast the air carries salt, and being older stock the splits here are frequently well used, so they face corrosion and heavy duty at the same time.
The result is a distinct pattern of faults. Salt corrodes the outdoor coil fins and cabinet while years of hard summer running wear out the capacitor, fan motor and compressor, and the brazed coil joints corrode until refrigerant leaks. When a Frankston split cools weakly or shuts down, we diagnose whether it is corrosion, a worn part or lost charge before we quote a thing.
The faults we see most on Frankston split systems — based on the local homes, install styles and conditions.
Frankston’s bayside air corrodes the outdoor coil fins and cabinet so the condenser cannot shed heat. We assess the extent, clean and treat what can be saved, and give honest advice when a unit is beyond economic repair.
Older Frankston splits run hard every summer, and the capacitor, fan motor and compressor wear out. We test each under load and fit the failed component rather than replacing a whole system that has plenty left in it.
Salt eats the brazed joints on coastal units, so a Frankston split slowly loses charge and cools poorly. We pressure-test to pinpoint the leak, repair it, and re-gas to spec rather than simply topping it up.

One local team for the whole system — from a not-cooling diagnosis and re-gas to parts, board repairs and an annual tune. Need a hygiene clean instead? We do that too.

Not cooling or heating? We fault-find the whole system — refrigerant, electrics, sensors and board — and tell you plainly what it needs.

Low on refrigerant means a leak. We pressure-test, find and repair the leak, then re-gas to the correct charge — not just a top-up.

A full service and tune — pressures, electrics, capacitor, fan and drain checked so the system runs efficiently and reliably.

When a Frankston split stops cooling we run it, read any codes and test the refrigerant pressures, capacitor, outdoor fan motor and board, and we always inspect the outdoor unit for the salt corrosion that is common this close to the water. On older stock the fault is often a mix of a worn part and a corroded coil.
The usual repair is fitting a failed capacitor or fan motor, or finding and sealing a leak on a corroded joint and re-gassing to the correct charge. We re-test cooling and heating output afterwards, and where a unit is too corroded to justify further spend we tell you plainly rather than sinking money into it.
FreshDuct repairs and services split systems across Frankston and Frankston South 7 days a week, and we regularly work in Dandenong, Clayton, Oakleigh and Ringwood, so a Frankston job fits neatly into our south-eastern run.
From the older homes near the foreshore and Olivers Hill to the family houses around Karingal and Frankston East, we can usually offer a prompt appointment and prioritise a system that has failed in the heat.
A methodical diagnosis and repair — we find the actual fault, quote it clearly, and fix it right the first time.
We run the system, read any error codes and test the electrics, sensors and refrigerant pressures to find the real fault, not just the symptom.
If it is low on gas we pressure-test to find the leak — a re-gas without fixing the leak just fails again in a season.
You get a clear, itemised quote before any part is fitted — capacitor, fan motor, PCB, sensor or a re-gas, with honest advice on repair-versus-replace.
We fit the part, repair the leak and re-gas to the manufacturer charge, then re-test cooling and heating output.
Electrics, contactor, fan, drain and airflow checked and tuned so the system runs efficiently and reliably.
A clear report with photos and honest advice on whether to keep servicing or plan a replacement.

“Bedroom head was throwing an error code and shutting down. They diagnosed a faulty PCB, quoted it and had it running the next visit.”

“Honest team — the outdoor fan motor had failed and they replaced it rather than pushing a whole new system. Saved me a fortune.”
Verified
“Great communication. They tested the capacitor and pressures, showed me the readings and explained exactly what was wrong.”
Verified
“Multi-head system, one room never cold. They tracked it to a blocked drain and low charge on that circuit and sorted both.”

“Quick, professional and tidy. The report and photos showed exactly what they checked and fixed on the unit.”

It depends how far the corrosion has gone. If the coil fins and cabinet are only surface-affected and the fault is a worn part, a repair is well worth it. If the coil is heavily eaten and leaking at multiple joints, we will say so honestly and talk you through repair versus replacement rather than pouring money into a failing unit.
That is the classic sign of a system low on refrigerant, and on a coastal unit the leak is usually at a corroded coil joint. Undercharged, it cools poorly, freezes on the indoor coil and eventually cuts out. We pressure-test to find the leak, repair it and re-gas to the correct charge rather than just topping it up.
Yes. FreshDuct diagnoses and repairs split systems across Frankston and the surrounding bayside south-east, 7 days a week — not-cooling and not-heating faults, re-gas and leak detection, error codes and parts for all major brands. Call 04 3191 8137 or request a free quote.
It is usually one of a few things: low refrigerant from a slow leak, a failed capacitor or fan motor on the outdoor unit, a blocked filter or coil, or a fault on the control board. We diagnose the actual cause rather than guessing, and quote the repair before we start.
We do, but a split system is a sealed circuit — if it is low on gas it has a leak. A top-up alone just leaks out again within a season, so we pressure-test to find the leak, repair it, then re-gas to the correct manufacturer charge.
It depends on the age, the brand and the fault. A capacitor, fan motor or sensor on an otherwise sound unit is well worth repairing; a failed compressor or a leaking coil on a 12-to-15-year-old system often is not. We give you honest, itemised advice either way.
Not-cooling & not-heating diagnostics, gas re-gas and leak detection, error-code faults, capacitor, fan-motor and board repairs, and an annual tune — a clean, documented service with photo proof. Available 7 days.
