Carbon monoxide (CO) is a colourless, odourless, and potentially deadly gas produced as a byproduct when gas appliances burn fuel. While all gas appliances create some level of carbon monoxide, properly functioning systems keep those levels within safe limits. The danger arises when faults, poor maintenance, or inadequate ventilation cause incomplete combustion—resulting in unsafe CO emissions.
Older appliances, especially open-flued systems, are particularly vulnerable to producing unsafe levels of CO if airflow or combustion conditions are compromised. Tragically, incidents like the death of Victorian Sonia Sofianopoulos in 2017 serve as a heartbreaking reminder of the very real risks associated with unmonitored gas appliances.
At Melbourne Gas & Air Conditioning Group, we take these risks seriously. Our technicians are trained in advanced carbon
monoxide testing and follow strict procedures to identify, measure, and address potential hazards. We use calibrated detection equipment and perform thorough assessments to ensure every system operates safely and efficiently.
If you have a gas appliance in your home-especially an older model-it’s essential to have it checked regularly. A carbon monoxide test could save a life.

Commonly speaking, we hear about carbon monoxide leaks within faulty gas heaters. However, carbon monoxide is created from other sources. Fire appliances that burn wood, gas, coal or oil has the potential to leak carbon monoxide. Vehicle exhaust systems also produce carbon monoxide.
Gas hot water units, gas cooking appliances, space heaters, and gas dryers can all produce high levels of carbon monoxide.
All though carbon monoxide is odourless, colourless, tasteless, and cannot be identified by the human senses, there are some vital signs that consumers can look out for to determine if they are exposed to carbon monoxide.
From a visual inspection, consumers should be looking out for the following around gas appliances.
If you, or someone you know, continue to have the below symptoms, medical advice should be sought. Should the medical professional not be able to provide a definitive answer as to why these symptoms are present, it is encouraged to have a qualified gas service technician check the living conditions to ensure there is no carbon monoxide present.
Common symptoms of carbon monoxide exposure are:
An issue with our gas industry is that some cleaning companies offer ductwork cleaning with a complementary carbon monoxide test. However, the majority of these companies are not qualified type A gas service technicians.
The carbon monoxide testing they carry out is not in line with the Australian gas servicing standard AS4575 and carries no legality or insurance to the occupants should something happen with that appliance and carbon monoxide.
These companies are providing false reassurance to unknown occupants and consumers.
In order for a gas inspection to be compliant, it must be carried out by a licensed type A gas service technician and carried out to the Australian standards AS4575 Appendix E
If you engage anybody to complete gas service work or carbon monoxide testing, always ask to see their VBA plumbing practitioner card, and look for the tick on “Gas Servicing- Type A”
You should never engage a carbon monoxide test on its own. A gas service is to be completed, and upon completion of the service, the company will complete the carbon monoxide test. Any companies that are offering a carbon monoxide test on its own, and not a service, are offering false security and are non-compliant with the Australian gas standards. There is no such thing as a carbon monoxide test on its own that complies with Australian gas standards.
Common symptoms of carbon monoxide exposure are:
Having your appliance regularly serviced by a reputable gas service company is the best way to ensure your gas heaters safety.
Absolutely not. If you smell gas around any appliance, shut the gas down, ventilate the area and call a gas fitter immediately for a service and inspection.
No, Carbon monoxide is odourless, colourless, tasteless, and cannot be identified by the human senses
They are carried out by a qualified type A gas service technician in line with Australian standards- AS4575 Appendix E
