Gas heaters should be professionally serviced every 2 years in the ACT, according to Energy Safe guidelines. A standard gas heater service in Canberra costs between $120 and $250 depending on the type of heater and accessibility, and includes a safety inspection, cleaning, and carbon monoxide check. Getting your heater serviced before winter is one of the smartest things you can do for both your safety and your energy bills.
How Often Should You Service a Gas Heater in the ACT?
The recommended servicing interval for gas heaters in the ACT is every 2 years. This aligns with manufacturer recommendations and Australian Standards for gas appliance maintenance. Some manufacturers specify annual servicing for older units, so it is worth checking your heater's manual or data plate.
If your heater is more than 10 years old, annual servicing is a good idea regardless of the manufacturer's recommendation. Older heaters are more likely to develop issues with heat exchangers, burners, and seals that can affect performance and safety.
Landlords in the ACT have specific obligations around gas appliance safety. If you are renting out a property with a gas heater, regular servicing is not optional. It is part of your duty of care to tenants.
What Is Included in a Gas Heater Service?
A proper gas heater service is more than a quick look and a dust-off. Here is what a thorough service includes:
- Visual inspection: Checking the heater, flue, and gas connections for visible damage, corrosion, or wear
- Burner inspection and cleaning: Removing and cleaning the burner assembly to ensure even flame distribution
- Heat exchanger check: Inspecting for cracks or deterioration that could allow combustion gases to leak into your living space
- Carbon monoxide testing: Using a gas analyser to measure CO levels in the flue gases. This is the most critical safety check.
- Gas pressure test: Confirming the gas supply pressure is within the correct range for the appliance
- Thermostat and controls check: Testing that the heater responds correctly to temperature settings and safety controls
- Flue inspection: Checking the flue pipe for blockages, disconnections, or damage that could prevent combustion gases from venting safely
- Filter cleaning: Cleaning or replacing air filters to maintain airflow and efficiency
How Much Does Gas Heater Servicing Cost in Canberra?
According to industry data from ServiceSeeking and Hipages, gas heater servicing costs in Australia typically range from $120 to $250. The price depends on several factors:
- Type of heater: A simple wall-mounted space heater is quicker to service than a ducted gas heating system
- Accessibility: Heaters in tight spaces, on roofs, or under floors take longer to access and service
- Age and condition: Older heaters may require more extensive cleaning and testing
- Parts replacement: If components need replacing during the service, this is an additional cost on top of the service fee
For ducted gas heating systems, expect to pay toward the higher end of the range. These systems have more components, longer flue runs, and require more time to service properly. Our ducted heating and cooling service covers the full system from the unit through to the ductwork and outlets.
What Are the Signs Your Heater Needs Servicing Sooner?
Do not wait for the 2-year mark if you notice any of these warning signs. They indicate your heater needs immediate attention:
- Yellow or orange flame: A healthy gas flame is blue. A yellow or orange flame means incomplete combustion, which produces carbon monoxide. Turn the heater off and call a licensed gas fitter immediately.
- Unusual smell: A faint gas smell when the heater first starts can be normal, but a persistent smell of gas or a sharp, acrid odour is not. Turn off the heater and ventilate the room.
- Pilot light issues: If the pilot light keeps going out, it could indicate a faulty thermocouple, a blocked pilot tube, or a draft issue with the flue.
- Soot or discolouration: Black soot marks around the heater or on nearby walls suggest incomplete combustion.
- Strange noises: Banging, popping, or rattling sounds can indicate loose components, a dirty burner, or expansion issues in the heat exchanger.
- Heater struggles to warm the room: If your heater is running but the room is not getting warm, it could be a burner issue, a blocked filter, or a problem with the ductwork.
Why Is Carbon Monoxide Testing So Important?
Carbon monoxide is odourless, colourless, and potentially fatal. A cracked heat exchanger or blocked flue can allow CO to leak into your home without you knowing. According to the Australian Government, carbon monoxide poisoning causes multiple deaths in Australia each year, many of them preventable with regular appliance servicing.
Symptoms of low-level CO exposure include headaches, dizziness, nausea, and fatigue. These are easily mistaken for the flu, which is why CO poisoning is sometimes called "the silent killer." A properly serviced heater with a functioning flue eliminates this risk.
If you do not have a carbon monoxide alarm in your home, consider installing one. They are inexpensive and provide an additional layer of protection between services.
What Is the Difference Between Ducted and Wall Heater Servicing?
Both types of gas heater need regular servicing, but the process is different:
Wall-mounted space heaters are relatively simple to service. The burner, heat exchanger, and flue are all accessible from one location. A standard service takes 30 to 60 minutes and sits at the lower end of the cost range.
Ducted gas heating systems are more complex. The central unit needs servicing (burner, heat exchanger, fan motor, filters), but the ductwork also needs inspection for leaks, disconnections, or insulation damage. A thorough ducted system service can take 60 to 90 minutes and costs more due to the additional work involved.
Why Should You Service Before Winter in Canberra?
Canberra winters are cold. Overnight temperatures regularly drop below zero from June through August, and most homes rely on gas heating to stay comfortable. The worst time to discover your heater is not working is the first cold night of the season.
Booking your gas heater service in autumn (March to May) gives you several advantages:
- Availability: Gas fitters are less busy before winter than during it. You will get an appointment sooner.
- Time for repairs: If the service reveals a problem that needs parts or more extensive work, you have time to get it sorted before you actually need the heater.
- No emergency callouts: A heater that breaks down on a freezing night becomes an emergency. A service in April that catches the issue is a standard appointment at standard rates.
