Appliances connected and certified, leaks made safe, and heaters properly tested for carbon monoxide before a cold Macarthur winter rather than during one.

Campbelltown sits inland, and the winters are genuinely cold. Overnight temperatures through the season drop close to freezing.
Which means a gas heater in this district is not decorative. It runs hard, and it runs for months rather than the odd fortnight, and everything inside it wears at the rate it is used.
The part that matters is the heat exchanger. When one cracks, combustion products including carbon monoxide can enter the room instead of going up the flue, and carbon monoxide has no colour, no smell and no taste at all.
People put the headaches and tiredness down to winter. The tell is that it lifts when you go out and returns when you come home. A combustion test takes minutes and is the only way to actually know, which is why we would rather do it in March than in July.


No switches, no power points, no phone indoors. Open what you pass on the way out, turn it off at the meter if you safely can, then ring us from outside.
Open the house up, get everybody outside, and touch nothing electrical on the way past. Ring from outdoors rather than from the room that smells.
Turn the gas off at the meter if you can reach it safely. On a back-to-front block that meter is at the road, which is behind the house.
A licensed gas fitter answers when you ring us, and where the network's emergency crew is the right first call we will say so.
Overnight temperatures here get close to freezing through winter, considerably colder than the coastal suburbs, so heating runs hard and runs for months.
An appliance working that hard for that long is doing more cycles than the same unit would in a milder part of Sydney.
So servicing matters more here than the general advice suggests, and it matters most on the oldest appliances.
It has no colour, no smell and no taste. Nothing about a room tells you it is there, and nothing about using the heater feels different.
That is the entire reason this page exists. Every other fault on this site announces itself eventually. This one does not.
Which is why the check is a schedule rather than a response to a symptom.
It is the classic cause, and you cannot see it by looking at the unit. The appliance lights normally, gets hot normally, and looks exactly as it always has.
Finding it means opening the appliance and inspecting the exchanger, which is part of a proper service and is not something anybody can do from the room.
That is the difference between a service and a glance, and it is worth asking which one a quote covers.
A flame burning yellow or orange instead of crisp blue. Soot or brown staining above or around the appliance. Condensation on windows when the heater runs.
None of those is proof of anything on its own, and all of them are worth a call rather than a wait.
Headaches or nausea that improve when you leave the house are worth taking seriously immediately, and that is a call to make from outside.
A service before the season costs the same as one during it, and it has the enormous advantage of being available. In the first cold week every gas fitter in Sydney is booked.
It also means a fault is found while you still have time to deal with it rather than in the middle of the coldest fortnight of the year.
Book it in autumn. It is the single most useful sentence on this page.
An unflued heater discharges its combustion products into the room it is heating. That is how it works, and it is why they are not permitted in a bedroom or a bathroom.
A lounge becomes a bedroom when a family grows, and the heater does not move. That is how a legal installation ends up somewhere it is no longer allowed.
It is worth a look if the use of any room in your house has changed.
Unflued heaters are approved on the basis of a stated room volume and a stated amount of fixed ventilation, and sealing those vents up defeats the approval.
It happens for entirely reasonable reasons, usually draughts, and nobody thinks of a wall vent as part of a gas appliance.
So if a room has been draught-proofed or reworked around a heater, that is worth mentioning when you book.
Adding an appliance is a calculation against total demand rather than a connection. The line has a capacity and so does the meter.
The input rating on the appliance plate is the number the calculation runs on, and a photograph of it is enough to start.
Where the sums do not work, appliances starve each other, and a burner that drops off whenever somebody runs a shower is nearly always this.
Every gas job finishes with a Certificate of Compliance recording who did the work, that they held a licence, and that the installation met the standard on the day.
Keep it with the property papers. It is what an insurer asks for after an incident and what a conveyancer asks for at sale, and it cannot be recreated afterwards.
A service report is worth keeping alongside it, because on a heater the history of what has been checked is genuinely useful.
Fixed price agreed before we start. These are indicative 2026 ranges. The Certificate of Compliance is included on every gas job and is never charged as an extra.
Any hour. Isolated and made safe first, then diagnosed properly.
Combustion tested, heat exchanger and flue inspected, ventilation confirmed.
Cooktop, oven, heater or bayonet onto an existing point, tested and certified.
Priced on the length of the run and what it has to get through.
On every gas job we complete. Legally required, and never an add-on here.

On a suspected leak the supply is isolated first. Diagnosis comes after the property is safe, never before.

Combustion measured at the appliance, heat exchanger and flue inspected, room ventilation confirmed against what the unit needs.

Put right where it can be. Where a unit fails it is disconnected and tagged rather than left running, and we explain exactly why.

Tested again on completion and your Certificate of Compliance issued on the spot.
Get everyone outside, avoid anything that could spark, and ring us from outdoors. A licensed gas fitter answers at any hour and we treat it as urgent.

Stop reading and act. Do not touch a light switch, a power point or anything that could spark, and do not use a phone inside the building. Open doors and windows on the way out, turn the gas off at the meter if you can safely reach it, get everyone outside, and ring from outdoors. We answer 24 hours. A gas smell is the one plumbing problem where waiting until morning is never the right call.
Because Campbelltown winters are cold and the heaters get used properly. Overnight temperatures here drop close to freezing, so a gas heater in this district runs harder and for more weeks of the year than one that gets switched on a handful of times. Everything that wears in a heater, the burner, the seals, the heat exchanger, wears faster with use. A unit that gets a genuine workload deserves a genuine service.
Carbon monoxide is produced when a gas appliance does not burn cleanly, and it has no colour, no smell and no taste. The danger with an unflued or poorly maintained heater is that nothing warns you. Symptoms get mistaken for winter illness: headache, tiredness, nausea, all of which improve when you leave the house and come back when you return. A cracked heat exchanger is the classic cause and it is not visible from the front of the unit. Testing is the only way to know.
We check combustion at the appliance with a calibrated analyser, inspect the heat exchanger, check the flue is intact and drawing where there is one, and confirm the room has the ventilation the appliance actually requires. It takes a fraction of the time people expect. If a unit fails, it gets disconnected and tagged rather than left running until somebody gets around to it, and we explain plainly what failed.
Worth knowing, though none of them are reliable enough to depend on. A flame that burns yellow or orange rather than crisp blue, soot or brown staining around the unit, a pilot that keeps going out, excessive condensation on windows when it runs, and a smell that is not gas but not right either. Any of those is a reason to stop using it and have it looked at. The absence of all of them is not proof it is safe.
Always, on every gas job, without asking. A Certificate of Compliance is a legal requirement for gas work in NSW and it is your evidence the work was done under licence and tested afterwards. Keep it. Insurers ask for it, and so does anyone buying the house. If a gas fitter does not hand you one, that tells you something important about the work.
A leak test and make-safe runs $200 to $450. A heater service with combustion and carbon monoxide testing is $180 to $350. Connecting an appliance to an existing point is $250 to $550. A new gas point is $450 to $1,200 depending on the run. The compliance certificate is included on every gas job and is never charged as an extra.
Tell us what the appliance is and roughly how old it is. If it is a heater and anyone in the house has been getting headaches, say so, because that moves it up the list.
Fixed price agreed first, combustion tested properly, and a Certificate of Compliance in your hand before we leave.
