Ducted Gas Heater Service and Repairs in the Southern Highlands
Ducted gas heater service and repairs carried out by licensed gas fitters across Bowral, Mittagong, Moss Vale and Berrima. TempcoFRH services Brivis and Rinnai ducted gas heating systems in homes throughout the Southern Highlands, covering annual maintenance, fault diagnosis, carbon monoxide testing and safety inspections. A ducted system that has sat idle since last winter needs checking before you rely on it again.
What a Ducted Gas Heating Service Includes
A ducted gas heater service covers both the combustion side of the unit and the ductwork that carries the warm air through your home. Each step below addresses a specific variable that affects how the system runs and whether it is safe to use.
Burner cleaning
Removing carbon deposits and debris from the burner assembly that reduce heat output and increase gas consumption.
Heat exchanger inspection
Checking for cracks and corrosion. On a ducted system a failed heat exchanger can put combustion products into the air the house circulates, so this is the single most important check of the visit.
Carbon monoxide testing
Measuring carbon monoxide levels to confirm nothing is spilling from the combustion chamber into the supply air travelling through your ducts.
Flue and ventilation check
Confirming combustion gases are venting to the outside correctly and that the flue is clear, sealed and properly supported.
Gas connections inspection
Inspecting the supply line, isolation valve and fittings for corrosion, deterioration or leaks, and confirming gas pressure at the appliance.
Ignition and pilot check
Testing the ignition sequence and flame sensing, including the pilot assembly and thermocouple on older Brivis and Rinnai units.
Thermostat and zone control testing
Confirming the unit cycles accurately to the set temperature, and that zone dampers open and close as they should so each area gets the heat it is called for.
Return air filter and ductwork
Cleaning or replacing the return air filter, and checking accessible ductwork for leaks, disconnected joints or crushed sections that waste the heat you are paying for.
At the end of the visit your technician talks you through the condition of the heater, anything found along the way, and any repairs worth booking before the next service. Call 02 4862 5595 to arrange a ducted gas heater service.
Licensed & Insured Local Team
Only a licensed gas fitter should service your ducted gas heater
A ducted gas heater is a combustion appliance sitting in your roof or under your floor, pushing air through every room in the house. Get the work wrong and the consequences are not a noisy fan, they are carbon monoxide. Every TempcoFRH ducted gas heater service is carried out by a fully licensed gas fitter working to Australian safety standards and manufacturer specifications. We carry $20M public liability cover and we are based here in the Southern Highlands, not driving down from Sydney. Quotes upfront, no surprises at completion.
Repairs & Diagnostics
Warning Signs Your Ducted Gas Heater Needs Repairs
Faults develop between services. Some creep in as components wear, others turn up the first cold morning you switch the heater on. If your ducted gas heater is doing any of the following, it needs looking at.
Heater won't ignite, or the pilot won't stay lit on older units.
Flame burns yellow, orange or red rather than a clean steady blue.
Unit short-cycles or cuts out before reaching the set temperature.
Gas smell near the appliance or supply connections. Do not book a service, see below.
Heat output has dropped without any change to settings or usage.
Soot or discolouration visible around the heater body or return air grille.
Fan runs but the outlets are blowing cool or barely warm air.
Some rooms heat while others stay cold, or a zone no longer responds.
If you can smell gas, don't book a service. Act now.
Turn the heater off at the isolation valve if you can reach it safely, open windows and get everyone outside. Don't touch light switches, don't use your phone indoors and don't light anything. From outside, call the gas emergency line on 131 909, or 000 if the smell is strong. Once the supply is made safe, call us on 02 4862 5595 and we'll take it from there.
A yellow or orange flame means incomplete combustion, which raises carbon monoxide output and drops efficiency. Ignition faults usually trace back to a worn thermocouple or a failing gas valve, and uneven heating across zones is more often a damper or control fault than the heater itself. Every ducted gas heater repair starts with full fault diagnosis before any parts are ordered. If a repair isn't worth it against the age of the unit, we'll tell you that before any work starts. Call 02 4862 5595 to book a diagnosis.
Why Service Your Ducted Gas Heater?
A ducted gas heater that misses its annual service rarely fails on the spot. The risks build quietly instead: carbon monoxide, warranty cover lapsing, and the mid-winter breakdown that was preventable back in autumn.
Safety
A cracked heat exchanger or blocked flue on a ducted system does not stay in one room. The fan pushes whatever is in that cabinet through the ductwork and out of every outlet in the house. Carbon monoxide is colourless, odourless, and undetectable without testing equipment.
Air Quality
A ducted system pulls the air in your home through the return air filter and pushes it back out again, over and over, all winter. Cleaning the burner and the filter keeps dust, debris and combustion residue out of that loop.
Lower Running Costs
A clean, well-adjusted burner and a clear filter mean the heater uses less gas to reach the set temperature and hold it. Across a full Highlands winter, that difference shows up on the bill.
Warranty Compliance
Most manufacturers, Brivis and Rinnai included, require annual servicing by a licensed gas fitter to keep warranty cover active. Every TempcoFRH service is carried out to manufacturer specifications and current Australian requirements.
Longer Heater Lifespan
A worn part caught during a scheduled service gets replaced on your timeline rather than taking other components with it. Ducted units that are serviced every year routinely outlast ones that are only looked at when something goes wrong.
Consistent Comfort
Even heat from every outlet, with each zone doing what the controller tells it. No back bedroom that never quite gets there while the lounge cooks.
Ducted gas heaters should be serviced every 12 months. Call 02 4862 5595 to book yours in before the cold sets in.
Ducted Gas Heating Systems We Service
TempcoFRH services ducted gas heating across the Southern Highlands, whatever the configuration and wherever the unit happens to sit. All work is carried out by licensed gas fitters to Australian gas safety standards.
Roof-Mounted Units
The most common setup in Highlands homes. Service covers the burner, heat exchanger and flue up in the roof space, along with the return air filter and airflow across every outlet.
Under-Floor & External Units
Subfloor and outdoor-mounted units cop the weather and the damp, so flue seal integrity and corrosion get particular attention. A compromised flue is one of the most common ways carbon monoxide finds its way back inside.
Zoned & Add-On Cooling Systems
Multi-zone ducted systems, and Brivis Duel Comfort units running add-on cooling off the same ductwork. We test dampers, zone controllers and changeover so each area gets what it is asked for.
Not sure which type you have? Most people don't. Call 02 4862 5595 and we'll work it out on the phone.

Frequently Asked Questions
How often should a ducted gas heater be serviced?
Every 12 months. Annual servicing keeps the unit running safely, keeps manufacturer warranty cover active, and gives a licensed gas fitter the chance to catch a developing fault before it turns into a breakdown in the middle of a Highlands winter. Most manufacturers, Brivis and Rinnai included, make annual servicing by a licensed gas fitter a condition of warranty.
Which ducted gas heater brands do you service?
Brivis and Rinnai ducted gas heating systems, across roof-mounted, under-floor and external unit configurations, including multi-zone systems and Brivis Duel Comfort units running add-on cooling.
If you are not sure what you have, call 02 4862 5595 and we will work it out from the model plate or a photo.
Can a ducted gas heater cause headaches?
Headaches, dizziness or nausea while a gas heater is running can be signs of carbon monoxide exposure. Treat it as urgent.
Carbon monoxide has no colour and no smell, and a ducted system moves air into every room in the house, so it does not stay near the heater. Turn the heater off, get everyone and any pets outside into fresh air, and leave the doors open behind you. If anyone is unwell, drowsy or confused, call 000. If symptoms are milder, see a doctor and tell them you suspect carbon monoxide, because it will not show up unless they are looking for it. Symptoms that ease when you leave the house and come back when you return are a strong sign.
Do not run the heater again until a licensed gas fitter has inspected it. A cracked heat exchanger or a blocked flue is the usual cause, and neither is visible from the outside. Once everyone is safe, call us on 02 4862 5595.
How much does it cost to service a ducted gas heater?
It depends on the type and condition of the unit, where it sits, and whether the inspection turns up anything that needs repair. You get the quote before we start, and if we find a fault we tell you what the repair costs before any parts are ordered.
Call 02 4862 5595 for a quote on your system, or request one online.
How far ahead should I book a ducted heater service?
Autumn, if you can. Everyone in the Highlands discovers their heater has a problem on the same cold morning, and the diary fills accordingly. Booking before the season starts means you get a time that suits you rather than whatever is left.
Call 02 4862 5595 to get in the book.
