Hawthorn mixes grand Victorian and Edwardian homes with converted flats and rental share-houses, and many run older ducted gas heaters that get heavy winter use. FreshDuct services them safely — carbon monoxide test, burner clean and a full function check.
Heater not used since last winter? Book a service and CO test before you fire it up.
Hawthorn is a grand inner-eastern suburb — ornate Victorian and Edwardian houses, mansion conversions and blocks of flats, plus a large student and rental population near the universities. Ducted gas heating is common in the bigger homes, and it often gets long, hard use through winter with less attention over summer.
A heater that idles all summer and then runs flat out from May onwards needs a proper start-of-season check. We service the burner and heat exchanger, run a carbon monoxide test and make sure the ignition and controls are reliable — so a Hawthorn home is warm from the first cold night without any nasty surprises.
The things we check first on a Hawthorn ducted gas heater — based on the local homes, systems and conditions.
Heaters idle all summer in Hawthorn then run hard all winter. Before the first proper burn we CO-test the unit and inspect the heat exchanger so nothing unsafe gets missed.
A heater that has sat unused can be slow or reluctant to light. We clean the burner and injectors and test the ignition and thermocouple so it fires first time every time.
Grand Hawthorn homes often keep a large, ageing ducted heater. We assess it honestly and let you know whether a service will see it through or whether it is time to plan a replacement.

The best time to service a Hawthorn ducted heater is autumn, before you actually need it. We pull the covers, clean the burner, inspect the heat exchanger and run a carbon monoxide test, then fire it up and confirm it heats cleanly and reliably.
For rentals and share-houses we can deal directly with tenants or agents and turn a service around quickly. We check the ignition, thermostat and airflow, and give a clear report on the heater’s condition — useful whether you own the home or manage it.
FreshDuct services ducted gas heaters across Hawthorn and Hawthorn East 7 days a week, and we regularly work nearby in Kew, Camberwell, Richmond and Balwyn, so we can usually reach a Hawthorn job quickly.
From the mansions along the river to the flats and share-houses near the campuses, we handle owners, tenants and agents alike and can prioritise a heater that will not start before a cold snap.
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 — autumn is the ideal time. A ducted heater that sat idle all summer should be serviced and carbon-monoxide tested before you run it hard through winter, so a reluctant burner or a compromised heat exchanger is caught before you rely on it.
Yes. We service and CO-test ducted heaters in Hawthorn rentals and share-houses regularly, coordinate access with tenants or the managing agent, and provide a clear written report on the heater’s condition for the owner.
Yes. FreshDuct services, tunes and carbon-monoxide tests ducted gas heaters across Hawthorn and the surrounding inner 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.
