You Can't See It. You Can't Smell It.
Carbon monoxide is an odourless, colourless gas produced whenever gas, wood, or other fuels burn incompletely. A faulty gas heater — one with a cracked heat exchanger, blocked flue, or poorly calibrated burner — can flood your home with CO while you sleep, completely undetected.
Critically, standard smoke alarms do not detect carbon monoxide. Millions of Australian homeowners mistakenly believe they are protected because they have smoke detectors fitted. They are not. CO alarms exist separately — and even those only alert at dangerous threshold concentrations, missing the slow chronic low-level exposure that damages health over weeks.
Energy Safe Victoria (ESV) records dozens of CO incidents in Victoria every year directly linked to poorly maintained gas appliances — many in homes that appeared perfectly normal.

New Home Buyers
Pre-purchase CO checks give you documented proof of appliance safety — and leverage in price negotiations if faults are found.

Renovators
Structural changes and new exhaust fans alter your home's pressure balance — creating dangerous back-drafting risk that only testing can confirm.

4 Signs Your Gas Heater Is Dangerously Unsafe

Yellow or Sooty Flame
A healthy gas burner produces a crisp, blue flame. A yellow, orange, or sooty flame indicates incomplete combustion — the primary cause of carbon monoxide production. Do not ignore this.
Visible Warning
Soot or Scorch Marks
Black staining around the heater grille, burner area, or flue outlet is a clear sign that exhaust gases are not venting properly. This means CO is almost certainly entering your living space.
Physical Evidence
Pilot Light Blowing Out
A pilot light that extinguishes repeatedly often signals a negative pressure problem — exhaust fans or draughts pulling combustion gases back into the home instead of up the flue.
Appliance Fault
Unexplained Physical Symptoms
Headaches, nausea, dizziness, or fatigue that improve when you leave the house and return when the heater is on are classic early CO poisoning symptoms. Evacuate and call us immediately.
Health EmergencyWe Don't Just Guess. We Measure.

Visual & Ventilation Inspection
We examine every gas appliance, flue, and ventilation point for physical damage, blockages, soot deposits, and signs of backdrafting.

Negative Pressure Testing
We test how exhaust fans, range hoods, and other depressurisation sources affect the spillage behaviour of your gas heater under real-world conditions.

Advanced Analyser Probe Testing
Using calibrated electronic CO analysers, we measure the exact parts-per-million (PPM) of carbon monoxide in your exhaust gases and living spaces — not guesswork.

Digital Certificate & Report
A full written service report covering all inspection points, CO measurements, flue readings, and compliance status is emailed to you the same day.

“We booked a routine CO test after having headaches every time the heater was on. The technician found a cracked heat exchanger leaking carbon monoxide directly into our living room. They literally saved our lives. Do not skip this test.”
“As a landlord I need to stay compliant with the 2-year gas safety rule. These guys service all four of my properties and send me legally recognised compliance reports the same day. Makes audits effortless and my tenants feel safe.”
“My gas heater is 14 years old. The CO test found it was spilling small amounts of carbon monoxide — totally undetectable without proper equipment. They fixed the problem on the spot. Worth every cent for the peace of mind alone.”
“All my managed properties are now on an annual CO testing schedule. The reports are detailed, professional, and satisfy all Residential Tenancies Act requirements. Quick turnaround and no hassle whatsoever.”
“Had a pre-purchase CO and gas safety check done on the house we were buying. Turned out the previous owner's heater had a dodgy flue. We used the report to renegotiate the price. Absolutely invaluable for any home buyer.”
“I was sceptical about whether CO testing was necessary for a heater only 8 years old. The technician's PPM reading showed levels three times what's considered acceptable. Old doesn't matter — it's the condition that counts. Completely eye-opening.”
“The digital service report I received covers every inspection point, CO measurements, flue readings, and next service recommendation. My insurance company actually requested a copy. The thoroughness of these guys is second to none.”

Yes. Under the Residential Tenancies Act 1997 (as amended) and Energy Safe Victoria guidelines, Victorian landlords must have all gas appliances professionally serviced at least every 2 years and keep records of compliance. Failure to comply can result in significant penalties. Our reports are legally recognised documentation.
A CO alarm is a backup warning device — not a substitute for professional testing. Alarms only trigger at dangerous threshold levels; they won't detect the slow build-up of CO that causes chronic health effects over weeks or months. They also cannot test your flue system, heat exchanger integrity, or exhaust gas composition. Professional testing and an alarm together is the correct approach.
Energy Safe Victoria recommends all gas appliances be serviced at least every 2 years. However, ESV also advises annual testing for households with vulnerable occupants (elderly, young children, or people with respiratory conditions), heaters older than 10 years, and any property where occupants have reported unexplained headaches or nausea.
If our calibrated analyzer detects CO spillage above safe thresholds, we will immediately condemn the appliance and advise you on safe next steps — which may include repair or replacement. We carry many common replacement parts and can often rectify the issue on the same visit. You receive a full written report documenting all findings regardless of outcome.
