Microbial Contamination

June 28, 2019
The definition of Microbial Contamination is the non-intended or accidental introduction of microbes such as bacteria, yeast, mould, fungi, virus, prions, protozoa or their toxins and by-products. This is a huge problem in the Top End. We have the perfect weather conditions for bacteria to breed and thrive in our air conditioners. We’ve all been warned of the health effects of mould, but do you consider this is what is growing inside your air conditioner and being spread through your house?
Is Microbial Contamination Affecting Your Health?

Air conditioning units have contributed to reducing the number of air pollution particles entering your house. However, if not properly maintained Microbial contamination within your air conditioning systems has been associated with many different health risks.The health risks include but are not limited to breathing problems, cold and flu, coughing, sore throat, nasal congestion and irritation, headaches, dizziness, nausea and asthma attacks.

Microbial contamination has also been to blame for Building Related Illnesses such as “Sick Building Syndrome”. A large number of commercial properties globally are affected by this, but with our tropical climate is a huge problem in Darwin, being linked with measurable declines in staff efficiency, increased absenteeism and reduced occupant wellbeing.

Microbial Contamination Affecting the Life Span of Your Air Conditioner


As microbial contamination circulates the systems airflow becomes restricted. Within the system pressures increase and the delivery of conditioned air into the occupied areas may be dramatically reduced. This increases the running cost of the unit, something that none of us can afford at the moment in Darwin. It also increases the costs of remediating a contaminated AC system.


Years ago, there was a case in the Northern Territory with a building that was no more than four years old. The microbial contamination was so bad that the building was condemned whilst the remediation works took place. The total of the restoration bill was in excess of $1,400,000.00. Of which less than 10% was the remediation cost of the AC system. A comprehensive HVAC Hygiene program for a building this size would not even equaled $1,000,000.00 in more than thirty years. After severe fungal growth has been able to lay siege to a building or it’s AC System, many components may need costly repairs or replacement.
