Reservoir is one of Melbourne’s biggest northern suburbs, full of post-war brick homes running long-serving ducted gas heaters. FreshDuct services them the honest way — carbon monoxide test, burner and heat-exchanger check and a filter clean.
Post-war home with an ageing heater? Book a service and CO test before the cold sets in.
Reservoir is one of the largest suburbs in Melbourne’s north, a broad spread of post-war brick and weatherboard family homes with newer infill filling the gaps. Ducted gas heating is everywhere in the older housing, and a great many of these homes still run the system fitted decades ago.
A long-serving Reservoir heater carries the usual age-related wear — a dust-choked filter, tired ignition parts, a heat exchanger due for inspection. We clean and tune the burner, replace the small worn parts, inspect the exchanger and run a carbon monoxide test so an older heater across this big northern suburb keeps running safely.
The things we check first on a Reservoir ducted gas heater — based on the local homes, systems and conditions.
Reservoir is vast, but its post-war homes share one weakness: a return-air filter thick with years of dust. We clean the burner and renew the filter so the unit can finally breathe.
So many Reservoir homes have a rear extension the original heater never allowed for. We check the vents and fan so the added rooms warm up alongside the front of the house.
Whichever part of this big suburb you are in, the safety check does not change — a heat-exchanger inspection and a carbon monoxide spillage test on every service.

Reservoir is one of Melbourne’s largest suburbs, and we service ducted heaters right across it — from Edwardes Lake to Keon Park — to the same standard. Clean and tune the burner, inspect the heat exchanger, renew the filter and run a carbon monoxide test, whichever street you are on.
The recurring Reservoir job is a heater struggling to warm a home that has been extended out the back on the original ducting. We rebalance the airflow to the added rooms and tune the unit, so warm air reaches the whole house instead of stopping at the old back wall.
FreshDuct services ducted gas heaters right across Reservoir — one of the biggest suburbs in the north — 7 days a week, from Edwardes Lake through to Keon Park.
We are constantly nearby in Preston, Coburg, Bundoora and Northcote, so wherever in Reservoir you are we can usually offer a prompt autumn slot and prioritise a heater that has stopped working.
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.

It can, but usually only after the airflow is rebalanced. A rear extension added on the original ducting often leaves the new rooms cold. We check the vents and fan, tune the heater and get warm air reaching the whole house, and advise if the unit is undersized for the larger home.
Yes. Reservoir is large, but we service ducted heaters across the whole suburb to the same standard — burner clean, heat-exchanger inspection, filter and airflow check and a carbon monoxide test — from the streets near Edwardes Lake to the homes out towards Keon Park.
Yes. FreshDuct services, tunes and carbon-monoxide tests ducted gas heaters across Reservoir 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.
