•Aircons can house bacteria’s, germs, mould and even some viruses which can cause health problems when the peoples inhales the air from such an air conditioning system.

•Aircons can be a source of respiratory infections which can range from less severe to more severe infections. For instance, example of less severe infections includes common cold and more severe infections include legionellosis which is a severe lung infections and its highly deadly.

•The causative bacteria of legionella infections mostly take residence in Aircons system and its spread very fast especially stagnant water and we know that some Aircons system uses water cooled circuits.

•On such a situation bacteria multiplies at very higher rate and then they are realised to air and when a person breath the droplets of contaminated water, one contract this deadly infection.

3.Results to respiratory diseases
