Dirty duct systems are the major source of indoor air pollution. Every time the air conditioner is turned on, contaminants are spewed out and circulated throughout your building, affecting the health and comfort of everyone in it.

For many years, hygiene in ventilation systems has been neglected. But, building managers now realize that fouled and dirty air systems affect the working environment, the comfort and health of staffs and customers. A drop in productivity, low employee morale, absenteeism, computer downtime, ruined interior decorations and ultimately, the high cost of replacing a prematurely deteriorated air conditioning system are all symptoms of a 'sick' duct system.

The American College of Allergists found that 50% of all illnesses are either caused by, or aggravated by, polluted indoor air. Cleaning your duct system will not only eliminate air pollutants, but also bring obvious health benefits as well as an enhanced system so your electricity bills are 10 to 25% lower (American Society of Heating, Refrigerating, and Air-Conditioning Engineers, 1987).
