Large Glen Waverley family homes often run several split systems — a living-room head plus bedroom units — and after a decade of hard use the boards and sensors start playing up. FreshDuct diagnoses the actual fault and repairs it, all major brands.
A split flashing a fault code and cutting out is usually telling you something specific — we read it, we do not guess.
Glen Waverley is a large, established south-eastern suburb of solid brick-veneer family homes, many extended over the years to cool several rooms at once. It is common here to find a main living-area split working alongside two or three bedroom units, and a good number of those systems are now well into their working life rather than brand new.
When a house runs that many indoor heads, the faults tend to be electronic as much as mechanical — a control board that resets, an indoor sensor reading wrong, or a contactor that no longer pulls in. Some newer inverter units add their own quirks. We read the fault codes, test the boards and sensors, and tell you exactly which unit needs what.
The faults we see most on Glen Waverley split systems — based on the local homes, install styles and conditions.
On homes running several splits it is often a control board that faults, resetting the unit or refusing to start. We test the board, the low-voltage supply and the connections before condemning it, then fit the correct replacement.
A unit that flashes a code and stops is reporting a defined problem — sensor, communication or protection fault. We read the code against the maker’s table and test the circuit it points to rather than clearing it and hoping.
Indoor and pipe sensors drift with age and make a split cool erratically or cut short. We measure each thermistor against spec and replace the faulty one so the unit reads the room correctly again.

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.
View service →

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

Capacitors, fan motors, PCBs, sensors and contactors sourced and replaced for all major brands, with a clear quote first.

Need a hygiene clean instead? Deep coil and barrel-fan cleaning, mould treatment and sanitising for cleaner, healthier air.

In a Glen Waverley home with several heads, the first job is finding which unit is actually at fault and why. We run each system, read any stored codes, and test the indoor board, sensors and the outdoor condenser so we are not chasing the wrong unit around the house.
From there the fix is targeted — a replacement thermistor, a reflowed or renewed control board, a new contactor, or a proper leak repair and re-gas if a circuit is genuinely low. We re-test cooling and heating on the repaired unit so you know that head is back to full output.
FreshDuct repairs and services split systems right across Glen Waverley 7 days a week, and we are regularly on jobs nearby in Clayton, Box Hill, Oakleigh and Ringwood, so fitting a Glen Waverley call into the run is easy.
From the larger homes around the Kingsway and Springvale Road down to the family streets near the station, we can usually offer a prompt appointment and prioritise a house left without cooling in a heatwave.
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.”
Verified
“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.”
Verified
“Quick, professional and tidy. The report and photos showed exactly what they checked and fixed on the unit.”

A code and a shutdown means the unit has hit a protection or sensor fault rather than simply losing gas. On the multi-split setups common in Glen Waverley homes it is often an indoor sensor, a communication fault between units or a tired control board. We read the code, test the exact circuit it points to and repair that, instead of clearing it and waiting for it to trip again.
Often yes, if the cabinet and compressor are sound and the fault is a board, capacitor or sensor. Those parts are replaceable and far cheaper than a new system. We tell you honestly when a unit is worth fixing and when age and repeated faults mean replacement is the smarter spend, so you are not pouring money into a dying unit.
Yes. FreshDuct diagnoses and repairs split systems across Glen Waverley and the surrounding 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.
