Sick Building Syndrome is a Real Problem. In commercial environments, the air delivery system is frequently cited as a major contributor. According to the National Institute of Occupational Safety and Health, occupants in buildings where the ducts have never been cleaned are 60% more likely to develop respiratory ailments.

Clean ducts can help improve air delivery systems and ensure an adequate supply of clean, fresh air. Furnishings, carpets and fabrics stay clean longer. Even the energy efficiency and service life of HVAC equipment can improve. And with healthier air, employees often experience fewer symptoms of illness and respiratory problems -- increasing performance while decreasing absenteeism.

IAQ related symptoms include; infection, migraine, tiredness, depression, eye irritation, headache, allergy and respiratory problems to name a few.
