Carbon Monoxide Testing

Carbon Monoxide Testing

Harley Plumbing provides carbon monoxide testing in the Melbourne Metro area. Carbon monoxide testing is imperative for all homes and businesses. If you have a gas appliance or gas heater in your home or rental then it must have carbon monoxide every 2 years. Harley Plumbing offers carbon monoxide testing in Melbourne for homes and businesses. Every gas heater should have regular carbon monoxide testing. In fact, it is a legal requirement for rental properties in Victoria. Carbon monoxide is a silent killer, the gas is odourless and colourless making it undetectable. It has claimed one life in Victoria every year and that’s one of the reasons the government has mandated compulsory carbon monoxide testing in Melbourne. Energy Safe Victoria states all homes to have their gas heaters serviced and tested once every 2 years.

Carbon monoxide happens when there is not enough oxygen for fuel. The lack of oxygen causes the fuel to produce CO and not CO2 (carbon dioxide). Harley Plumbing provides carbon monoxide testing for Melbourne commercial and residential properties. Carbon dioxide is a greenhouse gas and not poisonous, carbon monoxide is a poisonous gas. Even in small amounts, it is deadly. It kills by substituting oxygen in the haemoglobin in your blood, leading to asphyxiation. Often a person dies in their sleep or falls asleep due to lack of oxygen and then passes away, this is why it’s such a dangerous gas. 


Testing for a Carbon Monoxide Leak

Carbon monoxide (CO) cannot be detected by sight or smell. Specialist equipment is needed, however, there are a few small signs to look out for that may indicate your gas ducted heating is leaking CO

  • The pilot light often goes out
  • Heater switches off slightly
  • The flame in the burner is a strange colour and shows soot
  • Higher than normal gas bills
  • If the flame is any colour other than blue – yellow and green means there is a problem
  • Leaking gas attracts humidity meaning condensation on windows and surfaces
  • A build-up of soot around the furnace, ceiling and walls of the heater

What Causes a Carbon Monoxide Leak?

  • Faulty parts
  • Has not been regularly serviced
  • Heater is old
  • Heater does not run efficiently

What are the Signs of Carbon Monoxide Poisoning?

  • Mild to severe headache
  • Sudden onset of feeling tired
  • Shortness of breath
  • Feeling weak

If you or anyone in your home shows signs of these symptoms they need to be immediately taken outside in fresh air. For severe symptoms call an ambulance. Do not reenter the home until emergency services have cleared the property. Then air it out completely.
