Reservoir’s huge stock of post-war brick-veneer homes, many now rentals, runs plenty of ageing splits that are reaching the end of their working life. FreshDuct diagnoses the fault and gives you a straight repair-or-replace call, all major brands.
Before you replace an ageing split, get it diagnosed — sometimes it is a capacitor, sometimes the compressor is genuinely done.
Reservoir is one of Melbourne’s largest northern suburbs, built out with post-war brick-veneer homes across a huge area, and today a good share of them are rentals. The split systems in these houses were often fitted years ago and are now ageing units, worked hard because they carry both the summer cooling and a fair bit of the winter heating.
At that age, faults come thick and fast — a failed capacitor, a worn outdoor fan motor, a control-board problem or a compressor that is finally on the way out. For owners and landlords the real question is whether to repair or replace, so we diagnose the actual fault and give an honest answer rather than automatically condemning the unit.
The faults we see most on Reservoir split systems — based on the local homes, install styles and conditions.
Many Reservoir splits are old enough that several parts are wearing at once. We diagnose whether the fault is a cheap fix like a capacitor or a sign the unit is genuinely at end-of-life, so you spend money in the right place.
When an ageing Reservoir split stops cooling we test the capacitor, fan motor, charge and board in order to find the real cause, rather than assuming the worst and quoting a whole new system.
On the oldest Reservoir units the compressor itself can be the fault — drawing high current, tripping, or no longer building pressure. We test it properly, because a dead compressor is usually the point where replacement beats repair.

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 an ageing Reservoir split fails, the first thing we settle is whether it is worth repairing at all. We run the unit, read any codes and test the capacitor, fan motor, refrigerant charge and compressor, so we can tell you what has failed and what the repair would actually involve.
If it is a capacitor, fan motor or a repairable leak, we fix it and re-gas correctly — those are inexpensive against a new system. If the compressor is drawing high current or no longer pumping, we say so plainly, because on a tired unit that is usually the moment replacement makes better financial sense.
FreshDuct repairs and services split systems across the whole of Reservoir 7 days a week, and we are frequently working nearby in Preston, Coburg, Bundoora and Northcote, so a Reservoir booking fits easily into the run.
From the streets around Broadway and Edwardes Lake to the homes out towards Keon Park, we can usually offer a prompt appointment and prioritise a tenanted property 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.

“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.”

“Great communication. They tested the capacitor and pressures, showed me the readings and explained exactly what was wrong.”

“Multi-head system, one room never cold. They tracked it to a blocked drain and low charge on that circuit and sorted both.”

It comes down to what has failed. On the ageing splits common in Reservoir, a dead capacitor or fan motor is a cheap repair worth doing. But if the compressor is drawing high current or no longer building pressure, replacement usually wins. We diagnose the unit and give owners and landlords a straight recommendation with the numbers, not a sales pitch.
Yes. A lot of Reservoir is tenanted, so we regularly work with owners, agents and tenants to diagnose a faulty split, report what is wrong and quote the repair or replacement. We can attend the property, test the unit and provide the written detail an owner or agent needs to make the call.
Yes. FreshDuct diagnoses and repairs split systems across Reservoir 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.
