Coburg mixes post-war brick homes and older terraces, and most now lean on a single wall-mounted split for cooling. When that unit stops cooling, ices up or throws an error, FreshDuct finds the real fault — gas leak, capacitor, fan motor or board — and repairs it, all major brands.
One tired split doing all the work will eventually cut out on a hot day — we diagnose why, not just re-gas it.
Coburg is a settled northern suburb of interwar and post-war brick homes threaded through with older Victorian terraces, and cooling was almost always added later as a single split or two. Those units tend to carry the whole house through summer, so by the time they reach ten or twelve years old they are working hard with little margin left.
That is when the calls come in. A capacitor gives out, an outdoor fan motor seizes, or a refrigerant charge that has been quietly dropping for a couple of seasons finally leaves the unit icing up and cutting out. We test the electrics, the gas pressures and the control board to pin the actual fault before we quote a repair.
The faults we see most on Coburg split systems — based on the local homes, install styles and conditions.
Many Coburg splits are past ten years and running on original parts. We assess whether a failing compressor or corroded coil is worth repairing or whether a straight replacement makes more sense.
A single split cooling a whole Coburg house cycles hard every summer, so the run capacitor and outdoor fan motor wear out first. We test both and carry the common ratings on the van.
A unit that cools weakly then ices over is usually low on gas from a slow leak, not overdue a top-up. We pressure-test the circuit, repair the leak and re-gas to the correct charge.

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.

When a Coburg split stops cooling we run it on the meter, read any error codes and check the refrigerant pressures, the capacitor, the outdoor fan and the PCB. On an older unit several small faults can stack up, so we test the whole system rather than swapping the first part that looks tired.
From there it is an honest call. If it is a capacitor, a fan motor or a repairable leak we fix it and re-test the output the same visit. If the compressor is failing on a twelve-year-old unit we will tell you straight, so you are not pouring money into a system near the end of its life.
FreshDuct repairs and services split systems right across Coburg and Coburg North seven days a week, and we are often working close by in Brunswick, Preston, Reservoir and Northcote, so a Coburg job slots neatly into the day’s run.
From the brick homes around Bell Street to the terraces near Sydney Road, we can usually offer a prompt appointment and bump up a unit that has failed mid-heatwave with a house full of people.
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.

“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 on what has failed. A capacitor, fan motor or repairable leak is well worth fixing on an otherwise sound unit. But if the compressor is going or the coil is badly corroded on a twelve-year-old system, we will give you an honest repair-versus-replace figure so you can decide rather than spend on a unit near the end of its life.
That pattern almost always means the system is low on refrigerant from a slow leak. As the charge drops the coil ices over, airflow chokes and the unit cuts out until it thaws. We pressure-test to find where the gas is escaping, repair the leak and re-gas to the correct charge rather than just topping it up.
Yes. FreshDuct diagnoses and repairs split systems across Coburg and the surrounding northern suburbs, 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.
