What a ducted heating service costs in Sydney
A ducted heating service in Sydney is charged as a callout, a flat visit fee to inspect, clean and test one system, so the figure turns on whether it is a gas or a reverse-cycle unit rather than any area measure. A gas ducted service is the more involved job, because it centres on a safety check: testing the heat exchanger for cracks, checking the burner and flue, and testing for carbon-monoxide leakage, which is the real reason a gas heater should be serviced regularly. A reverse-cycle service is a clean and check of filters, coils and refrigerant.
Because Sydney's mild winters mean heating runs for only a short season, many households service a ducted system every couple of years rather than annually, though a gas unit used each winter is safest checked yearly for carbon monoxide. The city's highest trade rates push the callout above the national figure, and a strata apartment in the inner eastern suburbs may have its heating serviced under a building contract. A system near the salt air of the coast has its outdoor reverse-cycle unit checked for corrosion at the same visit.
A gas heater service must be done by a licensed gas fitter, because the carbon-monoxide and combustion checks are gas work, while a reverse-cycle service is done by a licensed refrigeration or ARC-certified technician with a licensed electrician for any electrical fault, under NSW Fair Trading. A basic filter clean the owner can do themselves between services. For a Sydney home, the clearest way to price a ducted heating service is per callout by system type, with the gas safety and carbon-monoxide check the core of a gas service.
