As the chill of winter approaches in Australia, it’s crucial to ensure that your gas appliances are in top-notch condition for both safety and efficiency. Regular maintenance of these appliances can prevent potential hazards and ensure they operate at peak efficiency during the colder months. Remember, carbon monoxide (CO) is a colorless, odorless gas that can be fatal. It’s important to have functioning CO detectors in your home to alert you to any potential leaks. Here’s a seasonal checklist to help you stay on top of gas safety and maintenance all year round.


  • Schedule a professional inspection of all gas appliances and systems to ensure they are operating correctly and safely.
  • Check the expiration date on your carbon monoxide detectors and replace them if necessary. Consider models that offer digital displays and battery backup for added safety.
  • Make sure that all vents and flues are clear of debris and obstructions to allow proper ventilation.


  • Test your carbon monoxide detectors monthly and replace batteries as needed or consider upgrading to detectors with a 10-year battery life for convenience.
  • Inspect gas appliance hoses and connections for signs of wear or damage and replace them if necessary.


  • Never use outdoor gas heaters indoors as they are not designed for enclosed spaces and can lead to CO buildup.
  • If you suspect a gas leak, turn off the appliance, open windows for ventilation, and contact a licensed gas fitter immediately.
  • Be aware of the symptoms of CO poisoning, which include headaches, dizziness, nausea, and breathlessness. If you suspect CO poisoning, seek fresh air immediately and call emergency services.


  • Once the cold season is over, it’s a good practice to have your gas appliances serviced and ready for the next winter.
  • Clean or replace filters in your gas heaters to maintain efficiency and improve indoor air quality.

Throughout the year, it’s crucial to be aware of the signs of a gas leak, such as a rotten egg smell, hissing sounds near gas lines, or dead houseplants.  If you suspect a gas leak, evacuate the area immediately and call your gas company from a safe distance. Do not attempt to locate the leak yourself.
