Coburg mixes Victorian cottages with solid post-war brick homes, many running ducted gas heaters fitted decades ago. FreshDuct services them the honest way — carbon monoxide test, burner and heat-exchanger check, airflow cleared.
Post-war heater getting noisy or slow? A service and fan check usually quietens it down.
Coburg is a solid, established northern suburb where Victorian cottages sit alongside rows of post-war brick and clinker homes, many built for families in the decades after the war. Ducted gas heating went into a lot of these homes and, in plenty of cases, the original system is still running.
A post-war-era heater that has warmed the home for decades tends to show its age in the same ways: noisy fan bearings, a burner in need of a clean, a heat exchanger that deserves inspection. An annual service keeps a Coburg heater quiet, efficient and safe, and every visit finishes with a carbon monoxide test.
The things we check first on a Coburg ducted gas heater — based on the local homes, systems and conditions.
Older Coburg heaters often get louder as fan bearings wear. We check the fan and belt, service what we can and tell you if a bearing or motor is on the way out.
Decades-old units deserve a careful safety check. Every Coburg service includes a heat-exchanger inspection and a carbon monoxide spillage test.
Years of dust load the return-air filter and grille of an older system. We clean and replace the filter so the heater breathes and warms the home efficiently.

A Coburg ducted heater that has run for thirty winters is often still worth keeping if it is looked after. We clean the burner, check the fan and belt, inspect the heat exchanger and run a carbon monoxide test before signing it off.
The usual Coburg complaints are a heater that has grown noisy or slow to warm the far rooms. That is generally worn fan bearings plus a choked filter, and we sort both — and we give you an honest view on how many winters the unit has left.
FreshDuct services ducted gas heaters across Coburg and Coburg North 7 days a week, and we work nearby in Brunswick, Preston, Reservoir and Northcote constantly, so a Coburg job is easy to fit in.
From the cottages near Bell Street to the post-war streets towards Merlynston, we can usually offer a prompt autumn service and prioritise a heater that has stopped firing.
A thorough, documented annual service — every component checked and a carbon monoxide test done before the cold sets in.
We check the whole ducted gas heater — burner, heat exchanger, gas valve, thermocouple, ignition and wiring.
A negative-pressure CO spillage test to make sure the heat exchanger is sound and nothing is venting into your home.
Burner, injectors and ignition cleaned and adjusted so the heater lights reliably and burns cleanly.
Return-air filter and supply vents checked and cleared so warm air flows freely to every room.
Thermostat, sensors and controls tested so the heater cycles correctly and holds the temperature you set.
A clear service report with photos and honest advice on whether to service or replace.

Usually, yes. A noisy older Coburg heater is generally worn fan bearings or a loose belt. We check and service the fan assembly, and if a bearing or motor is genuinely worn out we let you know rather than just masking the noise.
It can be, but only after a proper check. We inspect the heat exchanger for cracks and corrosion and run a carbon monoxide spillage test on every service. If the exchanger has failed we will tell you straight; if it is sound, a serviced unit is safe to run.
Yes. FreshDuct services, tunes and carbon-monoxide tests ducted gas heaters across Coburg and the surrounding northern suburbs, 7 days a week. Call 04 3191 8137 or request a free quote.
A standard annual service and carbon monoxide test is a fixed, affordable price; the cost only changes if the heater needs a part such as a thermocouple, igniter, filter or fan component — and we quote those clearly before we fit anything. Call 04 3191 8137 for pricing.
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.
Annual service and tune, carbon monoxide safety test, burner & heat-exchanger check, filter and airflow — a clean, documented service with photo proof. Available 7 days.
