Gas ducted heating in Sunbury
Gas ducted heating is what most Sunbury homes were built with, and a well maintained heater will keep doing the job for years. What it needs is a proper service by a licensed technician every year or two, with the heat exchanger inspected and the carbon monoxide check done, and a prompt repair when a fault appears in July. Because we are based in Sunbury, both are easy bookings. Our technicians are our own licensed employees, factory trained on Brivis and Rinnai and experienced with Braemar, Bonaire and every other major brand.
What a service covers
The heat exchanger is inspected and the carbon monoxide safety checks are done first, because that is the part of the service that protects the household. Then the burner and ignition are checked, the gas pressure and flue are checked, the fan and motor are tested, the filter is cleaned or replaced, the thermostat and controller are tested, the electrical connections are checked and the heater is run through a full heating cycle with the outlet temperature measured. You get a written report of what we found and a quote for any parts before they are fitted. The main service page covers the process in full.
Repairs
Tell us the symptom and any error code when you book and the technician comes with the likely parts. The Sunbury repairs we do most are ignition and flame-sensing faults, fan motors and capacitors, control boards, thermostats and heaters cutting out on an over-temperature limit because a duct is crushed or the return air is blocked. Water in the roof from a leaking evaporative cooler is a surprisingly common cause of a dead heater control board, and we check for it. Our guides on a gas heater that is not working and the Brivis and Rinnai error codes cover what you can check first.
When it is time to replace
We fix heaters that are worth fixing. A cracked heat exchanger, or a heater needing several major parts at once, is not, and we say so rather than sell a repair that will not hold. The Sunbury gas heater replacement page sets out the three real options, a like-for-like gas heater, a Braemar Dominator direct replacement that heats and cools, or a ducted reverse cycle conversion under the VEU program, and the site visit settles which suits the house. Our guide on repairing or replacing a gas heater explains how we make the call.
Local knowledge
What we see in Sunbury
A big stock of heaters from the 1990s and 2000s
Sunbury grew fast through the 1990s and 2000s and most of those homes were built with a gas ducted heater. Twenty to thirty winters on, the heat exchangers, fans and control boards are ageing together, which is why the heater service here is as much a safety check as a tune: a cracked heat exchanger is the fault that matters most, and it is found by inspection, not by symptom.
Roof-space heaters in double storey homes
Many Sunbury heaters are internal units in the roof space of a double storey home. Access, the condition of the ducts around the unit and the state of the return air are checked on the visit, because a heater that seems weak is often fighting a crushed or disconnected duct rather than failing itself.
The faults we see most
Ignition faults, fan motors and capacitors, control boards, flame sensors and thermostats are the Sunbury repairs we do most, and most of the parts for the common Brivis, Rinnai, Braemar and Bonaire models are carried, so a first-visit fix is the norm rather than the exception.
Heater and cooler the same age
A Sunbury home built with a gas heater usually got an evaporative cooler at the same time, so the two reach the end together. When the heater is past saving, the options are a like-for-like gas heater, a Braemar Dominator direct replacement, or a ducted reverse cycle conversion under the VEU program, and the Sunbury replacement page sets out all three.
Home base
We are based in Sunbury, so heater services here are often the first or last job of a technician's day and we can usually be flexible on times. Diggers Rest, Bulla and Toolern Vale are covered from the same depot.

Gas ducted heating in Sunbury: your questions
What does a Sunbury gas ducted heating service include?
Heat exchanger inspection, carbon monoxide safety checks, burner and ignition check, gas pressure check, flue check, fan and motor check, filter clean or replacement, thermostat and controller test, electrical connection check, a full run through the heating cycle and a written report. Any parts are quoted before we fit them.
How often should a gas heater be serviced?
Every two years at least, and every year on an older heater or one that runs hard through a Sunbury winter. The carbon monoxide check is the reason not to stretch it: a heat exchanger fault does not announce itself.
My heater is blowing cold air or cutting out. What is it?
Usually an ignition or flame-sensing fault, a fan or capacitor problem, or a heater cutting out on an over-temperature limit because the airflow is restricted. Tell us the symptom and any error code when you book, and the technician arrives with the likely parts. Our error code guides cover Brivis, Rinnai, Braemar and Bonaire codes.
Is it worth repairing a twenty year old heater?
For a fan, board, sensor or igniter on a heater with a sound heat exchanger, often yes. For a cracked heat exchanger, or several major parts at once, no, and we say so. Our guide on repairing or replacing a gas heater explains how we make the call, and the Sunbury replacement page sets out the options.
Can you service the evaporative cooler in the same visit?
Yes. Many Sunbury households book the heater service and safety check with the cooler clean in one visit.
