Aherne Air Conditioning is proud to support Carbon Monoxide Awareness Week

September 23rd – 29th was this years Carbon Monoxide Awareness Week and Aherne Air Conditioning, along with The AA, are delighted to be supporters. Carbon monoxide (CO) is an odourless, colourless and poisonous gas and is often referred to as the ‘Silent Killer’. The AA conducted a poll of over 7,600 people and despite 95% saying that they were aware of the dangers of carbon monoxide poisoning around 60% said they do not have an alarm.

How is CO formed?

When any fuel such as oil, wood, gas or coal is burnt, oxygen is added forming CO₂ but without proper ventilation during the combustion process, carbon monoxide can be produced. If you inhale carbon monoxide, it combines with blood and prevents it from absorbing oxygen. At high levels, it wouldn’t take long for unconsciousness or even death to occur. Poisoning could be a problem in your home as one of the main causes is faulty, damaged or badly-maintained heating or cooking appliances.


Some of the side-effects caused by carbon monoxide at lower levels are very similar to those caused by the common cold or flu, so unfortunately they can go unnoticed. For example, headaches, weakness, lethargy and dizziness. There are other symptoms too, such as nausea, diarrhoea, stomach pains and chest pains. However, a lot of these symptoms can also be explained away as common illnesses and may not be recognised as carbon monoxide poisoning immediately.


More and more homeowners are equipping their home with a carbon monoxide alarm but the problem is that there isn’t enough focus on maintaining the alarm. In The AA survey more than 15% of those who had a carbon monoxide alarm said that they hadn’t ever checked it or they couldn’t remember if they had. In fact only 42.5% said they had checked their alarm in the last month. It’s very important to follow the manufacturer’s guidelines to find out where to place the alarm and how often to test it. As a rule of thumb though, they should be checked once a month.

Prevention is always better than the cure so while carbon monoxide alarms can tell you if there is a problem, it’s no substitute for regular inspection and maintenance of appliances, chimneys, vents and flues.
