How Much Does Gas Heater Servicing Cost in Melbourne? (2026)

Gas Heater Service Costs in Melbourne — 2026 Guide

Gas heater servicing costs in Melbourne vary depending on the type of heater, its age, and how long since it was last serviced. Here's an honest guide to what you should expect to pay in 2026.

Ducted Gas Heater Service

A standard annual service for a ducted gas heater — covering safety inspection, heat exchanger integrity test, flue inspection, combustion analysis, filter clean, and burner inspection — typically costs $180–$280 in Melbourne's south-east. This is the full service, not just a function check. If the service uncovers a fault requiring parts, those are quoted separately before any work proceeds.

Wall Furnace and Space Heater Service

Wall-mounted gas heaters and space heaters are generally quicker to service than ducted systems. Expect $150–$220 for a standard service on a wall furnace, including the safety inspection and combustion check. Any parts required are quoted additionally.

What's Included in a Proper Gas Heater Service?

A thorough service should include: visual inspection of the unit and flue, heat exchanger integrity testing, combustion gas analysis, burner inspection and clean, gas pressure check, ignition system check, thermostat verification, and filter inspection. If a plumber just runs the heater and checks it turns on — that's not a service. At ATC Plumbing, every service is comprehensive and includes a written report.

Is It Worth Servicing an Old Heater?

Generally yes, up to about 15 years of age — provided the heat exchanger is sound. If the exchanger has cracked, the heater must be replaced. For heaters over 15 years old, a service combined with an honest condition assessment makes sense — a good plumber will tell you if spending money on a service isn't worthwhile.
