Domestic, Commercial and Industrial Air Conditioning systems act as the “Lungs†of the building and need to be maintained not only for cooling but more importantly for cleanliness. Over time, contaminants such as building debris, dust, hair, animal dander, fibers from clothing and carpets, pollen, tobacco residues and many more accumulate inside the ducts and on the cooling coils resulting in growth of bio-film, mould and bacteria that is well documented as a major cause of respiratory illnesses and triggering Asthma attacks. EPSCO Envirotech cleans the complete air duct system to the American standard ACR 2013. This standard produced by NADCA (National Air Duct Cleaners Association) is used worldwide to ensure systems are professionally cleaned.
