Essendon’s solid brick homes were built long before split systems, so today’s units sit on long refrigerant runs threaded through thick walls and roof spaces. Those long lines are where slow gas leaks start. FreshDuct finds and repairs the leak, then re-gasses to spec — all major brands.
Weak cooling that gets worse over weeks is a leak, not a unit that needs a top-up — we find where it is escaping.
Essendon is a suburb of solid double-brick and rendered homes, many from the interwar years, on established streets well back from the coast. None were built for air conditioning, so the split systems cooling them today were retrofitted — and in a heavy masonry house that usually means a long refrigerant line-set snaked through walls, ceilings and roof cavities to reach the condenser outside.
Every extra metre and joint on that run is another place refrigerant can slowly escape. An Essendon split that once cooled well but now struggles, ices up or cuts out is very often a system quietly low on gas because of a leak somewhere along that long line. We pressure-test the circuit, pinpoint the leak, repair it and re-gas properly, rather than pumping in more refrigerant to feed the same fault.
The faults we see most on Essendon split systems — based on the local homes, install styles and conditions.
Retrofitting a split into a solid Essendon home means long runs with more joints, and that is where charge escapes. We pressure-test and trace the circuit to the exact leak point, repair it, then re-gas to the manufacturer’s figure.
A system left running low on refrigerant makes the compressor work harder and hotter, which shortens its life. We catch and fix a leak early so the fault stays a cheap re-gas and does not become a failed compressor.
Many Essendon splits were fitted years ago and are now ageing. We test the charge, capacitor, fan motor and board together and give a straight repair-versus-replace answer instead of a piecemeal fix.

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.

When an Essendon split cools weakly and then stops, our first move is to confirm whether the circuit is low on refrigerant and, if it is, to find out why. A sealed system does not use gas, so a low charge means a leak — we pressure-test and work along the line-set, fittings and coils until we locate exactly where it is escaping.
Once the leak is found we repair the joint or component rather than simply adding gas, then re-gas the circuit to the correct weight and re-check pressures and output. That way the fix lasts, the compressor stops running starved and hot, and you are not back in the same spot a few weeks later with cooling fading again.
FreshDuct repairs and services split systems throughout Essendon, Essendon North and Aberfeldie, and we are often working nearby in Moonee Ponds, Coburg, Brunswick and Footscray, so an Essendon booking fits easily into the run.
From the period homes around Buckley Street to the family houses near Essendon station, we can usually offer a prompt appointment and will prioritise a system that has lost its cooling in the middle of 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.

“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.”

“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.”

Because a split system is sealed and does not consume refrigerant, so if it keeps running low it has a leak, not a normal top-up need. On the long line-sets common in solid Essendon homes those leaks are usually slow and hidden. We pressure-test to find where the gas is escaping and repair it, so a proper re-gas actually lasts instead of draining away again.
Yes, if it is left too long. A compressor running with a low charge works harder and runs hotter than it should, and over time that can wear it out or seize it — turning a cheap leak repair into a major replacement. Catching and fixing the leak early keeps it a straightforward re-gas and protects the most expensive part of the system.
Yes. FreshDuct diagnoses and repairs split systems across Essendon and the surrounding inner north-west, 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.
