Gas Ducted Heater Servicing in Melbourne


A gas ducted heater keeps the whole house warm through Melbourne's cold winters, but it is also the one appliance in your home that burns gas and pushes heated air into every room. That makes regular servicing a safety issue as much as an efficiency one. BM Heating & Cooling provides thorough gas ducted heater servicing across Melbourne, carried out by licensed gasfitters, from our base in the northern suburbs.

Every service includes a full clean, inspection and tune of the heater, and a carbon monoxide safety test. Carbon monoxide is colourless and odourless, and a cracked heat exchanger or a blocked flue can let it leak into the air your family breathes. The only reliable way to catch it is with proper testing during a service.

Energy Safe Victoria recommends having your gas heater serviced at least once every two years by a qualified gasfitter, and that the service includes testing for carbon monoxide. For older or heavily used ducted heaters we recommend a check every year, before winter. Whether you bought the system from us or not, we can look after it.

We service gas ducted heaters throughout Reservoir, Preston, Thomastown, Bundoora, Epping, Lalor, Mill Park, Coburg, Heidelberg, Northcote and right across the Melbourne metro area.

What a Gas Ducted Heater Service Includes


Our licensed gasfitters carry out a complete service, not just a quick once-over. Here is what is covered.

Burner and heat exchanger: clean and inspect the burner and check the flame pattern, then inspect the heat exchanger for cracks or corrosion, which is the part that can leak carbon monoxide if it fails.

Gas, ignition and controls: test the gas pressure to manufacturer spec, check the igniter, pilot and flame sensor, and confirm the thermostat controls the heater correctly.

Airflow and venting: clean or replace the return-air filter, check and clean the fan and blower motor, and inspect the flue and venting for blockages or corrosion so combustion gases exhaust safely outside.

Carbon monoxide safety test: using a calibrated CO analyser we test the combustion products and carry out a spillage test, including a negative-pressure test with exhaust fans running, to make sure no carbon monoxide is entering the home. We finish with a full operational test and an honest report.

Carbon Monoxide Safety and the Signs to Watch


Carbon monoxide poisoning is the reason gas heater servicing matters so much. A carbon monoxide alarm is a useful back-up, but Energy Safe Victoria is clear that an alarm is never a substitute for regular servicing by a qualified gasfitter. Book a service if you notice any of these warning signs.

A yellow or lazy flame: the burner should burn a crisp blue. A yellow, orange or flickering flame is a sign of incomplete combustion and a carbon monoxide risk.

Soot or staining: brown or black scorch marks or staining around the heater or vents.

Trouble running: the heater will not ignite, keeps shutting off, heats unevenly, is noisy, or your gas bills have climbed.

Flu-like symptoms: headaches, nausea or dizziness that ease when you leave the house can indicate carbon monoxide exposure. Turn the heater off and get it checked as a priority.

Why Regular Servicing Matters


Safety First

A service catches a cracked heat exchanger, a blocked flue or a carbon monoxide leak before it can harm your family, with a proper CO test every time.

Lower Gas Bills

A clean burner, filter and fan restore combustion efficiency and airflow, so the heater uses less gas to keep the house warm through winter.

Reliability & Warranty

Regular servicing means fewer mid-winter breakdowns, a longer life for the unit, and a documented history that keeps your manufacturer warranty valid.

How Often to Service, and the Brands We Look After


Have your gas ducted heater serviced at least every two years, in line with Energy Safe Victoria guidance, and every year for older or heavily used units. The best time is before winter, so any faults are found before you rely on the heater through the cold months. Many older northern-suburb homes run ageing ducted units that genuinely warrant an annual check and carbon monoxide test.

You do not need to have bought your heater from us for us to service it. Our licensed gasfitters work on all the major brands sold in Melbourne, including Brivis, Braemar, Bonaire, Vulcan and Rinnai.

If your heater is old and a repair is no longer safe or worthwhile, we will tell you honestly and explain your replacement options. For rental properties, we can also carry out the gas safety checks Victorian landlords are required to provide. There is no pressure and no upselling, just straight advice from a licensed team.

Gas Ducted Heater Servicing FAQs


At least once every two years, in line with Energy Safe Victoria guidance, and yearly for older or heavily used systems. Many Melbourne homes book a service before winter.

Carbon monoxide is colourless and odourless and can leak from a cracked heat exchanger or a blocked flue. A licensed gasfitter uses a calibrated analyser to test for it and for combustion spillage, which is the only reliable way to catch it.

Yes. Energy Safe Victoria is clear that a carbon monoxide alarm is only a back-up and is never a substitute for regular servicing by a qualified gasfitter.

Most gas ducted heater services take around an hour, depending on the system and access. If we find a fault we will explain it and quote any repair separately.

A yellow or lazy flame, soot or staining, gas smells, uneven heating, higher gas bills, strange noises, or trouble igniting. Flu-like symptoms that ease when you leave home can indicate carbon monoxide and should be treated urgently.

An unserviced heater is a higher carbon monoxide risk, especially older open-flued units. Have it tested before you run it through a Melbourne winter.

All major Melbourne brands including Brivis, Braemar, Bonaire, Vulcan and Rinnai, regardless of who installed it.

For rental properties, Victorian landlords have gas safety-check obligations. For homeowners, two-yearly servicing is a strong Energy Safe Victoria safety recommendation rather than a legal requirement.
