Carlton’s Victorian terraces, student housing and converted flats often run older or compact ducted gas heaters. FreshDuct services them safely — carbon monoxide test, burner clean and a proper ignition and controls check.
Heater in a rental sat unused all summer? Book a service and CO test before winter.
Carlton is a tight, historic inner-city suburb of ornate Victorian terraces, university housing and converted flats around Lygon Street and the campuses. Heating is a mix of old ducted gas systems in the terraces and compact units in the flats, and a lot of it is in rentals that see heavy but seasonal use.
A heater that idles all summer in a Carlton rental and then runs hard from autumn onwards needs a start-of-season service. We clean the burner, check the ignition and heat exchanger, run a carbon monoxide test and confirm the controls work — so the home is warm and safe when the cold arrives, and owners have a clear record of the unit’s condition.
The things we check first on a Carlton ducted gas heater — based on the local homes, systems and conditions.
After a summer idle, a Carlton heater should be CO-tested before heavy use. We inspect the heat exchanger and run a spillage test so a fault is caught before winter, not during it.
Heaters that sit unused can be slow to light. We clean the burner and injectors and test the ignition and thermocouple so a Carlton unit fires reliably from the first cold night.
For Carlton rentals we provide a clear written report on the heater’s condition and the CO test, useful for owners and managing agents.

A Carlton ducted heater is best serviced in autumn, before it is really needed. We clean the burner, inspect the heat exchanger, test the ignition and controls and run a carbon monoxide check, then fire the unit and confirm it heats cleanly.
For tenanted terraces and flats we coordinate access with tenants or agents and turn the work around quickly. We provide a plain written report on the heater and the CO test — the kind of record owners and property managers actually need.
FreshDuct services ducted gas heaters across Carlton and Carlton North 7 days a week, and we are regularly working nearby in Fitzroy, Brunswick, Richmond and Northcote, so a Carlton booking fits easily into our run.
From the terraces off Rathdowne Street to the flats near the university, we handle owners, tenants and agents and can prioritise a heater that will not start 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.

Yes. We service and carbon-monoxide test ducted heaters in Carlton rentals and student housing, coordinate access with tenants or the agent, and provide a written report on the heater’s condition and the CO test for the owner.
Have it serviced and CO-tested first. A ducted gas heater that has been idle all summer can have a dropped pilot, a dirty burner or, on older units, a compromised heat exchanger. A start-of-season service checks all of that before you rely on it.
Yes. FreshDuct services, tunes and carbon-monoxide tests ducted gas heaters across Carlton and the surrounding inner city, 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.
