Gas heater safety

Carbon Monoxide Testing before you switch the heater on.for a safe, warm winter.

Carbon monoxide has no colour or smell, so a faulty gas heater can leak it into your home without any warning. Our licensed technicians carry out gas heater carbon monoxide testing on ducted gas heating, space heaters and gas log fires, checking the heater and its flue while the system is running. A carbon monoxide test is included as standard in every All Good gas heater service.

Gas Heater Carbon Monoxide Testing at every point fumes can escape.

A gas heater that looks fine can still spill carbon monoxide if the burner is dirty, the flue is blocked or exhaust fans pull fumes back into the room. A proper carbon monoxide test checks all three with the heater running. Tap a number to see what we test.

Safety testing

Gas Heater Service with a carbon monoxide test included.

Carbon monoxide is produced when gas doesn’t burn completely. It has no colour, smell or taste, and the early symptoms, such as headaches, dizziness, nausea and tiredness, are easy to mistake for a cold or the flu. A cracked heat exchanger, a dirty burner or a blocked flue can let it into your home.

That is why a carbon monoxide test is part of every All Good gas heater service, not an extra. Carbon monoxide testing is a fixed flat fee of $239 for new customers and $229 for returning customers. We test ducted gas heating, gas space heaters and gas log fires, and explain the results before we leave.

Ducted gas heating & rentals

Ducted Heating Service & Gas Safety Checks for Homes and Rentals

Ducted gas heaters sit out of sight in the roof space or under the floor, so problems can go unnoticed for years. A ducted heating service with a carbon monoxide test checks the heater, the flue and the outlets, so fumes are not carried through the ducts into your living areas. We also carry out gas safety checks for rental properties. In Victoria, rental providers must have gas appliances checked every two years.

Out-of-sight heaters checked

What is carbon monoxide testing?

Carbon monoxide testing checks whether a gas heater is leaking combustion gases into your home. With the heater running, we sample the air around it with a carbon monoxide analyser, inspect the burner, heat exchanger and flue, then repeat the test with exhaust fans on and the home closed up.

How often should a gas heater be tested for carbon monoxide?

Energy Safe Victoria recommends having gas heaters serviced at least every two years, and the service should include a carbon monoxide test. Book sooner if the heater is old, has not been serviced for a while, or you notice any warning signs.

How much does carbon monoxide testing cost?

Carbon monoxide testing is a fixed flat fee: $239 for new customers and $229 for returning customers, applied automatically. The test is included as standard in every gas heater service. If we find a fault, we explain your options and give you a clear price before any repair goes ahead.

What are the signs of a carbon monoxide leak?

You cannot see or smell carbon monoxide, so watch for symptoms: headaches, dizziness, nausea, tiredness or shortness of breath that ease when you leave the house. Warning signs on the heater include a yellow or sooty flame instead of a blue one, soot stains around the unit and a pilot light that keeps going out. If you suspect a leak, turn the heater off, open doors and windows, go outside and seek medical advice. Call 000 in an emergency.

Is a carbon monoxide detector enough?

No. A carbon monoxide detector or alarm is a useful backup, but it only tells you once gas has already built up near the alarm. It does not replace a professional carbon monoxide test, which checks the heater and flue directly and finds faults before they become dangerous.

Can ducted heating leak carbon monoxide?

Yes, if it is a gas system. A cracked heat exchanger or a faulty flue on a ducted gas heater can let carbon monoxide into the airflow, and the ducts then carry it to every room. That is why we test at the outlets as well as at the heater.

Can an air conditioner leak carbon monoxide?

No. Split system and reverse-cycle air conditioners run on electricity and do not burn fuel, so they cannot produce carbon monoxide. The risk comes from gas appliances such as gas heaters, gas log fires and ducted gas heating.

Do rental properties need a gas safety check?

In Victoria, yes. Rental providers must have a gas safety check carried out on all gas appliances every two years by a licensed gasfitter, and keep a record of it. The check includes carbon monoxide testing on gas heaters.

Do I need to be home for the test?

Yes. Someone 18 or older should be there to provide access to the heater and exhaust fans, and so we can explain the results before we leave.
