A ducted gas heater sits idle for six months, then gets asked to run for hours a day. An annual service checks the burner, flame sensor, ignition, fan, filters, return air and flue, and every service includes a carbon monoxide test. Ducted gas heater service from $300 with no call-out fee, and you pay after the job.
Any one of these is worth a call. They rarely fix themselves.
The technician opens the heater, runs it, and works through the parts that decide whether it lights reliably, heats evenly and burns cleanly:
You get a plain report of what was found, with before and after photos. If the service turns up a worn or failed part, the technician inspects and quotes before any work, and you approve first.
Carbon monoxide is produced when gas does not burn cleanly. It has no colour and no smell, and in a home it shows up as headaches, drowsiness or nausea that ease when you leave the house. In a ducted gas heater the usual causes are a cracked heat exchanger, a blocked or disconnected flue, or a dirty burner.
Every ducted gas heater service includes a carbon monoxide test. With the heater running, the technician tests for carbon monoxide at the heater and in the warm air coming out of the outlets. If carbon monoxide is found, the heater is turned off and not left running, and you are told exactly why and what it would take to make it safe.
A battery carbon monoxide alarm near the bedrooms is a sensible extra layer for any home with gas heating. Our guide to carbon monoxide and ducted heating covers the symptoms and the warning signs in more detail.
The sensible time to service a ducted gas heater in Melbourne is autumn, before the first cold snap. A heater that has sat idle since spring can collect dust on the burner, the flame sensor and the fan, and the first hard run of the year is when a weak part tends to give out. Booking ahead also means you choose the day.
A short burning-dust smell for the first few minutes of the season is normal. A smell that lingers, a heater that cycles on and off, soot marks, a yellow flame or a gas bill that keeps climbing are not, and they are worth a service whatever the month. Our annual service guide explains what each of those signs usually means.
A service looks after the heater itself: burner, sensors, fan, flue and the carbon monoxide test. That is this page.
A duct clean deals with the ducts, outlets and return air path, where years of dust collect and get blown back into the rooms. Our ducted heating cleaning in Melbourne covers that.
A repair is for a heater with a fault: one that will not light, blows cold, shows an error code or keeps shutting down. Our ducted heating repairs page covers faults. You get a quote to approve before any work starts.
Replacement comes up when the heat exchanger has failed, the heater is very old, parts can no longer be sourced, or it has been turned off as unsafe. Our ducted heating replacement page sets out the options, and our ducted heating service cost guide explains what a service includes and what changes the price.
