Gas heaters should be serviced every two years by a licensed gasfitter, mainly for the carbon monoxide test. Faulty heaters have caused deaths, this is a safety service, not just maintenance.
A gas heater service is mostly a safety check, the carbon monoxide test can detect a cracked heat exchanger before it becomes dangerous. Book it in autumn before the winter rush for better price and availability.

What a gas heater service costs in Sydney
A gas heater service in Sydney is charged as a callout to inspect, clean and safety-test a standalone gas space heater, a flued wall or console heater or a portable one, rather than a whole ducted system, so the price turns on the heater type and its condition. The heart of the service is safety: the technician checks the combustion, inspects the heat exchanger or burner for cracks and faults, checks the flue on a flued heater, and tests for carbon-monoxide leakage, which is the core reason a gas heater is serviced.
Carbon monoxide is the real concern, because a faulty gas heater can leak the odourless, dangerous gas into a room, and an unflued portable gas heater also adds moisture and combustion by-products to the indoor air, so ventilation matters when one is used. Sydney's mild winters mean a space heater runs for only a short season, so many households service one every couple of years, though a unit used each winter is safest checked annually. The city's highest trade rates lift the callout, and a terrace or an apartment in the eastern suburbs with a single flued gas heater is a common case.
A gas heater service must be carried out by a licensed gas fitter in New South Wales, because the combustion and carbon-monoxide testing is gas work strictly licensed for safety under NSW Fair Trading, and it is not a do-it-yourself job. For a Sydney home, the clearest way to price a gas heater service is per callout by heater type, with the carbon-monoxide safety check the core of the visit on a space or wall heater.
