1. Dirty and unclean air conditioning ducts decrease the air quality and cleanliness of your indoor environment – deep-cleaning your air conditioning duct system, or ac duct system will remove contaminants from the system. Removing contaminants at the source stops the system from producing poor air into the indoor environment.

2. Dirty and unclean air conditioning ducts can trigger and promote symptoms of allergies, sore throat, runny nose and coughing – dirty and poorly maintained air conditioning duct systems produce poor air. Dust, fibres and dirt from the interior of the ducts can trigger cold like symptoms and even induce asthma or breathing difficulties in those susceptible.

3. Dirty and unclean air conditioning ducts promote Sick Building Syndrome (SBS) – Sick Building Syndrome was first reported on in the 70s and 80s. People in Office Buildings reported their buildings were making them sick. The most common causes of SBS are nasal congestion, breathing problems, headaches, tiredness and irritated skin. SBS has been linked to depression and poor mental health, and the rise of apartment living and tight urban developments has seen reports of SBS on the rise. Cleaning the ventilation and air conditioning systems is recommended to remove any build-up including mould, or microorganisms that may have spread in to the system.

4. Dirty and unclean air conditioning ducts may be increasing your visits to a GP – Oxford University studies have shown that individuals that spent more time in air conditioned surroundings also spent more time in the doctors office. An increase was noted in the number of ear-nose-and throat related problems, respiratory and dermatological issues. Sadly for business owners, this also increases absenteeism from the workplace. Inspection and deep-cleaning of the air conditioning systems you are regularly subjected to is highly recommended.

5. Dirty and unclean air conditioning ducts cause odours – the presence of mould and microorganisms within air conditioning ducts can bring a musty smell into the indoor environment. These smells may become less noticeable the longer you are exposed. Mould contamination can be treated with deep-cleaning or commercial agents such as Bactigas.

6. Dirty and unclean air conditioning ducts that are contaminated with mould are a health risk – the combination of air temperatures, moisture and unclean inner ducts can create the ideal breeding ground for mould, microbial growth and microorganisms. Mould can produce spores which can become airborne within the system, existing through air vents into the indoor environment. Mould can aggrevate breathing and respiratory ailments, as well as asthma, especially in children and the elderly.

7. Dirty and unclean air conditioning ducts can house vermin and pests – dirty duct systems can quite easily become home to vermin such as rats and mice. Often vermin and wildlife can become trapped and die within the duct systems and require manual removal. As air from the system passes over these decomposing animals, smells can be carried through the ducts into the indoor environment.

8. Dirty and unclean air conditioning ducts can cause decline in cognition and learning ability – with the latest research in poor air quality, decreases in cognition and learning ability, especially in elderly men, shows further cause as to the importance in keeping our indoor air environments as clean as possible, at all times.
