Brunswick’s Victorian terraces and workers’ cottages have been renovated hard, and many tuck a ducted gas heater into a tight footprint. FreshDuct services them properly — carbon monoxide test, burner clean and airflow check in a compact space.
Renovated terrace with a heater squeezed into a cupboard? We service it without the drama.
Brunswick is a dense, creative inner-northern suburb of Victorian terraces, single-fronted workers’ cottages and warehouse conversions along Sydney Road. Renovations have added rear extensions and second storeys, and ducted gas heating is often fitted into whatever tight space the layout allows — under the floor, in a cupboard or a compact roof cavity.
A heater packed into a tight Brunswick footprint still needs the same care as any other: a clean burner, a sound heat exchanger and clear airflow. Confined installs tend to load up with dust and restrict the return air, so an annual service keeps the unit breathing, efficient and safe, finished with a carbon monoxide test.
The things we check first on a Brunswick ducted gas heater — based on the local homes, systems and conditions.
Tight terrace installs often have an undersized or dust-choked return. We clean or replace the filter and check the airflow so the heater is not starved of air and running hot.
A heater in a cupboard or under the floor still needs a proper safety check. We inspect the heat exchanger and run a carbon monoxide spillage test on every Brunswick service.
A small heater warming a full terrace works hard. We clean and tune the burner so it delivers its output without labouring, straining the fan or running noisily.

Servicing a ducted heater in a renovated Brunswick terrace means working in a confined space, and we come prepared for it. We access the unit, clean the burner, inspect the heat exchanger, check the ignition and controls and run a carbon monoxide test.
In tight installs the usual issue is restricted airflow — a clogged filter or a cramped return leaving the heater short of breath. We clear the airflow path and tune the burner so the terrace warms quickly and the unit runs quietly, and we photograph anything that needed attention.
FreshDuct services ducted gas heaters across Brunswick, Brunswick East and Brunswick West 7 days a week, and we are constantly working nearby in Coburg, Northcote, Carlton and Fitzroy, so a Brunswick job is easy to reach.
From the cottages off Sydney Road to the warehouse conversions near the Upfield line, we handle tight inner-city installs every week and can prioritise a heater that has stopped working before a cold spell.
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.

“Great communication and a tidy job. They checked the thermostat and airflow and sorted a room that was never getting warm.”

Yes. Confined installs are normal for us in Brunswick. We access heaters under floors, in cupboards and in tight roof cavities, clean the burner, inspect the heat exchanger, clear the airflow and run a carbon monoxide test.
In a tight install it is usually restricted return air — a choked filter or cramped return grille starving the heater so it runs hot and cuts out on its limit. We clear the airflow and tune the burner so warm air actually reaches the rooms.
Yes. FreshDuct services, tunes and carbon-monoxide tests ducted gas heaters across Brunswick and the surrounding inner north, 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.
