Wondering what a ducted gas heating service should cost in Melbourne? FreshDuct charges a fixed, affordable price for a full service and carbon monoxide test, with any parts quoted clearly before we fit them — no surprises.
Quoted wildly different prices? Here is what actually drives the cost of a heater service.
The cost of a ducted gas heating service in Melbourne comes down to two things: the standard annual service and safety test, which is a fixed price, and any parts the heater turns out to need, which are quoted separately and clearly. FreshDuct keeps the base service affordable and transparent so you know what you are paying before we start.
A standard service covers cleaning and tuning the burner, inspecting the heat exchanger, checking the ignition, thermostat and airflow, and carrying out a carbon monoxide safety test. Where a heater needs a worn part — a thermocouple, an igniter, a return-air filter or a fan component — we quote the part before we fit it, so the only thing that ever changes the price is a repair you have approved.
The things we check first on a Melbourne ducted gas heater — based on the local homes, systems and conditions.
A full annual service — burner clean and tune, heat-exchanger inspection, ignition, thermostat and airflow checks — is a single fixed price with no hidden extras.
A negative-pressure CO spillage test is included in the service price, not charged as an add-on. It is the most important safety check on any gas heater.
If the heater needs a thermocouple, igniter, filter or fan part, we quote it before fitting. Parts are the only thing that changes the total, and only with your approval.

FreshDuct charges a fixed price for a standard ducted heating service and carbon monoxide test, whether the heater is a compact unit in a new townhouse or a larger system in an established home. You know the base cost before we arrive, and it does not move unless a genuine repair is needed.
If the service uncovers a worn part or a fault, we stop and quote it clearly — the part, the reason and the cost — before doing any extra work. That way the final bill is only ever the fixed service plus repairs you have approved, with photos of anything we replaced.

Every two years at a minimum, and ideally once a year before winter. An annual service in autumn means the burner, heat exchanger and controls are checked and a carbon monoxide test is done before you rely on the heater through the cold months.
Yes. Every ducted gas heater service we do includes a carbon monoxide safety check — we test for CO spillage and inspect the heat exchanger for cracks, because a faulty exchanger can leak carbon monoxide into the home. It is the single most important reason to service a gas heater.
