Carbon Monoxide Testing in Sydney
Carbon monoxide (CO) is invisible, odourless and deadly. Even low levels can cause serious health problems over time. HeaterCare performs advanced CO testing to detect risks before they become real dangers — so your family, tenants or staff stay safe.
What we test during a CO safety check
- Portable & fixed gas heaters
- Gas fireplaces & space heaters
- Gas cooktops, stoves & ovens
- Gas hot-water heaters & flues
- Ventilation, airflows & negative pressure
Why Carbon Monoxide Testing Matters
Many gas appliances — heaters, fireplaces, stoves and hot-water systems — can produce carbon monoxide if they’re faulty, poorly ventilated or incorrectly installed. Because CO is colourless and odourless, you won’t know it’s there until symptoms appear.
- Protect health: CO exposure can cause headaches, dizziness, nausea and, at high levels, can be fatal.
- Identify hidden faults: Abnormal CO levels often indicate leaks, poor combustion or flue issues.
- Meet obligations: Ideal for landlords, property managers and strata who must demonstrate gas safety.
- Peace of mind: Clear, documented results showing your home or property is safe.
Our CO Testing & Safety Check Process
We follow a structured process so nothing is left to chance.
1. Visual Inspection & Setup
- Check flues, vents, grills and clearances
- Inspect appliance condition, hose age & connections
- Confirm room ventilation & potential negative pressure issues
2. CO Monitoring & Combustion Tests
- Run appliances under normal conditions
- Use calibrated CO monitors to measure levels in living spaces
- Combustion analysis at the appliance and flue terminals
3. Reporting, Repairs & Certification
- Explain results in clear, simple language
- Carry out repairs or adjustments where required
- Retest and provide a written safety report/certificate for your records
Warning Signs of Possible Carbon Monoxide Exposure
- Headaches, dizziness or nausea that improve when you leave the property
- Unusual tiredness, confusion or “flu-like” symptoms with no clear cause
- Soot staining around heaters, fireplaces or flue terminals
- Condensation or staining on windows near gas appliances
- Pilot lights that keep going out or appliances burning with yellow/orange flames
- Family members or pets unwell at the same time when indoors
If you notice any of these signs, treat it as serious until proven otherwise.

Carbon Monoxide Testing – FAQs
Unsure if you need CO testing? These common questions may help. You can always call 0432 986 187 for tailored advice.
How often should I test for carbon monoxide? +
We recommend a CO safety check at least every 12 months, or sooner if you install new gas appliances, renovate, or notice any symptoms or warning signs.
Do you provide a written safety certificate? +
Yes. After testing, you’ll receive a written report or safety certificate that can be used for landlords, strata, property managers or insurance.
Is CO testing disruptive to my home? +
No. We use portable instruments and run tests while appliances are operating. Most checks take less than an hour and don’t require major disturbance.
How long does a CO test usually take? +
A standard CO test for a typical home takes around 30–60 minutes, depending on the number of gas appliances and the layout of the property.
Do I still need a CO test if I have alarms installed? +
CO alarms are important, but they don’t replace professional testing. Our checks confirm appliances are burning correctly and that CO is not building up in living areas.
