Box Hill blends established brick-veneer homes with a fast-growing crop of new apartments, so its splits range from end-of-life units to systems still under warranty. FreshDuct diagnoses the real fault — capacitor, fan motor, board or gas leak — and repairs it properly across all major brands.
Newer apartment split still under warranty? We can service it correctly and keep your warranty intact.
Box Hill is one of the eastern suburbs’ busiest centres, where long-standing brick-veneer family homes sit alongside a rapid rise of new apartment towers. That mix shapes the work we do here — older houses running splits well past a decade and now reaching end-of-life, and new units in apartments that are only a few years old and still inside their warranty period.
The faults split along the same lines. On the older brick-veneer systems we see worn capacitors, tired outdoor fan motors and failing boards, and often an honest repair-versus-replace conversation. On the newer apartment units the issues are usually installation-related or a warranty part, and we service them to the manufacturer’s requirements so the cover stays valid.
The faults we see most on Box Hill split systems — based on the local homes, install styles and conditions.
Many Box Hill splits in older homes are now at the end of their working life. We test the full system, and where a unit is leaking and needs a compressor or board, we tell you plainly that replacement is the smarter spend.
New Box Hill apartments run recent units still under manufacturer warranty. We service and repair them correctly, keep the paperwork right, and make sure the work does not void the cover you are entitled to.
On the mid-life brick-veneer systems the capacitor and outdoor fan motor are the usual failures after years of eastern-suburb summers. We test both together and carry the common parts to repair on the visit.

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.

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

When a Box Hill split stops cooling, the first thing we establish is the age and type of system, because an end-of-life unit in an older home and a near-new apartment unit call for very different approaches. We run the system, read any error codes, and test the capacitor, fan motor, refrigerant pressures and board to find the real fault.
On the older systems the answer is often a worn electrical part or, on a badly leaking unit, an honest case for replacement. On the newer apartment installs the fault is more likely a setup issue or a warranty-covered part, and we handle it so the manufacturer cover stays intact rather than being accidentally voided.
FreshDuct repairs and services split systems across Box Hill, Box Hill North and Box Hill South 7 days a week, and we are regularly nearby in Balwyn and Doncaster, so an eastern-suburbs booking fits our run neatly.
From the apartment towers around the station to the family homes stretching toward Glen Waverley and Ringwood, we can usually offer a prompt appointment and prioritise a system that has failed during a hot spell.
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.”
Verified
“Quick, professional and tidy. The report and photos showed exactly what they checked and fixed on the unit.”

No. Servicing a unit correctly is exactly what keeps a manufacturer warranty valid — it is neglect or unqualified work that voids cover. We service and repair recent Box Hill installs to the manufacturer’s requirements, use the right parts, and keep the records straight so your warranty stays intact throughout.
It depends on what has failed. A brick-veneer home’s split that just needs a capacitor or fan motor is well worth repairing, but an ageing R410a or R22 unit that has lost its compressor or leaks badly is usually at the end of its life. We test the whole system and give you the honest cost of repair against a new unit before you decide.
Yes. FreshDuct diagnoses and repairs split systems across Box Hill and the surrounding eastern 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.
Tell us the fault and your split system — we respond fast, 7 days.
