Eltham is mudbrick, timber and owner-built homes tucked into bush blocks, rarely following a standard plan. FreshDuct services their ducted gas heaters with care for the unusual layouts — carbon monoxide test, burner tune and every room checked.
Owner-built home with ducts in odd places? We work through the real layout, not a template.
Eltham is a distinctive, artistic north-eastern suburb famous for its mudbrick and timber homes, many owner-built on bushy blocks and shaped more by their makers than by any standard floor plan. Thick earthen walls, lofts, split levels and rooms that step down the slope all make for beautiful houses — and heating that rarely runs to a template.
A ducted gas heater in an Eltham home still needs the same core care, but the ducting and vents are often in unconventional spots that a routine service would miss. We work through the actual layout, tune the burner, inspect the heat exchanger, run a carbon monoxide test and make sure every room — loft or lower level included — is getting its share of warm air.
The things we check first on a Eltham ducted gas heater — based on the local homes, systems and conditions.
Eltham’s owner-built homes put vents and ducts in unusual places. We follow the real layout so lofts, split levels and thick-walled rooms all get their share of warm air.
However alternative the home, the gas heater is conventional and needs conventional care. We inspect the heat exchanger and CO-test the unit whatever the house is built from.
Many Eltham owners want their heating running as leanly as possible. We tune the burner and set the controls so the unit delivers warmth without wasting gas.

Servicing a heater in a mudbrick or owner-built Eltham home means paying attention to the layout as much as the unit. We tune the burner, inspect the heat exchanger and run a carbon monoxide test, then trace the ducting through the lofts, steps and thick walls to check the warm air is actually getting everywhere.
Thermal mass cuts both ways in these homes — slow to warm but slow to lose heat — so airflow and a well-tuned burner matter. We balance the vents to the real rooms and set the controls efficiently, and we show you exactly what we adjusted.
FreshDuct services ducted gas heaters across Eltham, Eltham North and Research 7 days a week, from the mudbrick homes on the bushy blocks to the houses near the township.
We work nearby in Greensborough, Bundoora, Reservoir and Doncaster too, and can usually offer a prompt appointment for an Eltham home whose heating is leaving some rooms behind.
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.

Yes. Eltham’s mudbrick and owner-built homes rarely follow a standard plan, so we work through the actual layout — lofts, split levels and thick-walled rooms included — tune the burner, inspect the heat exchanger and run a carbon monoxide test.
In an owner-built home the ducting and vents often sit in unconventional places, and thermal-mass walls warm slowly, so heat can be uneven. We trace the actual duct layout, rebalance the vents to the real rooms and tune the burner so the whole house heats as evenly as it can.
Yes. FreshDuct services, tunes and carbon-monoxide tests ducted gas heaters across Eltham and the surrounding north-east, 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.
