Signs You Need Emergency Gas Ducted Heating Repair

Melbourne winters can drop to single digits overnight. A ducted gas heater that fails mid-season is not just uncomfortable - for elderly residents, young children, and those with respiratory conditions, it can be a genuine health emergency. Knowing which warning signs warrant an immediate call could make all the difference.
“We woke up at 2am to the smell of gas and the heater making a loud banging sound. One call and a technician was at our door within the hour. Could not be more grateful.”
1. Strong Gas Smell Near the Unit
A gas smell near your heater is always a serious emergency. Turn off your gas at the meter immediately, do not operate any electrical switches, ventilate the property, and call both your gas provider and a licensed emergency gas fitter.
2. Loud Banging, Rattling, or Booming Sounds
A loud boom on ignition is often a sign of delayed ignition - gas has been building up in the combustion chamber before it catches. This can fracture the heat exchanger. Both scenarios require immediate professional inspection.
Never ignore unusual sounds from a gas appliance. What starts as a minor fault can become a dangerous failure within a single heating cycle.
3. Heater Short-Cycling
If your heater ignites and then shuts off after only a few minutes repeatedly, a safety limit switch is likely tripping due to overheating. This is commonly caused by blocked air filters, restricted return air, or a failing heat exchanger.
4. No Heat
If the fan runs but no warm air comes out, or if the unit refuses to ignite at all on a cold night, call our emergency line. Our technicians carry common igniter assemblies, gas valves, and circuit boards on-board for same-session repairs.
