Warning Signs

Is Your Ducted Gas Heater Not Working?

These are the faults our team gets called out for most across Sydney. If your system is showing any of these signs, do not wait until the coldest week of the year to deal with it.

Not igniting

System clicks but will not start. Usually a pilot light, igniter or gas valve fault.

Insufficient heat

Runs but cannot warm the house. Heat exchanger, burner or airflow issue.

Cycling on and off

System keeps cutting out. Often a thermostat, limit switch or gas pressure fault.

Unusual smells

Gas, burning or musty smells when heating runs. Do not ignore this — call immediately.

Pilot light out

Pilot keeps extinguishing. Thermocouple, draught, or gas supply issue.

No airflow from vents

Heat exchanger or blower motor fault. System running but no air movement in rooms.

Carbon Monoxide Safety

A cracked heat exchanger can leak carbon monoxide into your home. If you smell gas or have any concern about your system’s safety, call us immediately and do not run the system until it has been inspected.

How much does ducted gas heating repair cost in Sydney?
+
Most ducted gas heating repairs range from $150 to $600 depending on the fault. Common fixes like igniter or thermocouple replacements are at the lower end. Major component replacements such as heat exchangers or gas valves are higher. We always provide a written upfront quote before any work starts.
How much does a new ducted gas heating system cost?
+
A new ducted gas heating installation in Sydney typically ranges from $3,000 to $7,000 depending on the home size, brand selected, and whether existing ductwork can be reused. We provide a free on-site quote with a written price before you commit to anything.
How often should ducted gas heating be serviced?
+
We recommend servicing every 2 years as a minimum, annually for heavily used systems or older units. A proper service includes a heat exchanger safety check, burner inspection, filter clean, and gas pressure test.
My ducted heater turns on but doesn't heat — what's wrong?
+
This is usually a heat exchanger fault, a failed burner, low gas pressure, or an airflow restriction. It can also be a safety lockout triggered by an earlier fault. Do not keep resetting it — have it properly diagnosed.
Is it worth repairing an old ducted gas heater?
+
It depends on the age of the system and the nature of the fault. As a general rule, if your system is under 12 years old and the repair is under $800, repair is almost always the better investment.
Are your technicians licensed to work on gas heating?
+
Yes. All gas work in NSW must be performed by a licensed installer. Our technicians hold current gas fitting licences and all work comes with the required Certificate of Compliance.
