Gas appliances fail politely. A cooktop burner drifts out of tune, a heater's flue path gets compromised, a water heater's combustion slowly dirties, and none of it announces itself the way a burst pipe does. That is exactly why servicing runs on a calendar rather than on symptoms, and why the interval question deserves a proper answer rather than a scare campaign.
Recommended service intervals by appliance
| Appliance | Interval | Priority checks |
|---|---|---|
| Gas space heater (flued or unflued) | Every 1 to 2 years, ideally before winter | Combustion, flue integrity, CO spillage, ventilation |
| Gas hot water (storage or continuous flow) | Every 1 to 2 years | Burner condition, relief and tempering valves, connections |
| Gas cooktop and oven | Every 2 years | Burner tuning, flame quality, injector condition, isolation valve |
| Gas bayonet points and hoses | Check at every service | Seal condition, hose date stamps, connection integrity |
| Whole-of-home annual gas service with us | Yearly | All of the above in one visit, $150 to $200 |
What does a gas service actually involve?
A proper service is a combustion and safety inspection, not a wipe-down. We test each appliance for correct gas pressure and flame quality, check burners and injectors for blockage and drift, test flued appliances for spillage so combustion products are actually leaving the building, verify ventilation openings have not been blocked or built over since installation, leak-test connections and bayonet fittings, and on hot water units check the safety valves that protect the tank. The carbon monoxide side matters most on heaters: CO is colourless and odourless, and a heater that spills it into a closed winter room is the genuinely dangerous failure in domestic gas. Everything is done against AS/NZS 5601 and the appliance manufacturer's specifications, and you get told plainly what was tested and what, if anything, needs attention.
Why every 1 to 2 years and not longer?
Because that is the interval at which the slow failures become findable before they become dangerous, and it aligns with what appliance manufacturers themselves specify, commonly two years, with annual checks recommended for heaters that run hard every winter. Queensland's gas safety framework under the Petroleum and Gas (Safety) Regulation puts obligations around gas work and appliance safety, and while nobody will knock on a homeowner's door demanding a service logbook, landlords should note their obligations run higher: rental properties need their gas installations maintained in a safe condition, and a documented service history is how that is evidenced. For owner-occupiers, the practical logic is simpler. A $150 to $200 annual visit is cheap insurance against the two expensive outcomes: a CO incident, or an appliance failure discovered on the first cold night of July when every gas fitter on the Gold Coast is already booked.
What are the warning signs I should not wait on?
Book straight away, regardless of when the last service was, if you see any of these. Yellow or lazy orange flames where there should be crisp blue, which signals incomplete combustion. Soot marks around a burner or flue. A pilot light that keeps going out. Any smell of gas, which is a stop-and-call situation, not a service booking: leave the appliance off, ventilate, and ring a licensed gas fitter or the gas emergency line before anything else. Headaches, drowsiness or nausea that improve when you leave the room are the classic CO exposure pattern and warrant both a doctor and a gas fitter. And after any flood event or renovation near gas lines, have connections checked even if everything seems to work, because disturbed pipework is a leak risk we regularly find months after the event.
Who is allowed to service gas appliances in Queensland?
Only a licensed gas fitter. All gas fitting work in Queensland, including servicing, disconnection and repair, sits under the Petroleum and Gas (Safety) Regulation 2018 and requires a gas work licence, separate from a standard plumbing licence. A general handyman cannot legally service your heater, and neither can an unlicensed mate with the right spanners, because the service's value is the combustion testing and the accountability behind it. When you book anyone, ask for their gas work licence number. We hold ours alongside QBCC licence 15243081, we do the whole-of-home service in a single visit for $150 to $200, and we put in writing what was tested, what passed, and anything we recommend, priced fixed before any extra work happens.
When should I book mine?
If you cannot remember your last gas service, that is your answer. The best timing is autumn for heater households, so any fault is found before winter, and any time of year for cooktops and hot water. One visit, every appliance, $150 to $200.
