Dirty air duct systems are a Major source of indoor air pollution. Airborne contaminants are pulled into the air ducts every time the heating and cooling system runs. Over time, these contaminants build up inside the ductwork, creating an ideal breeding ground for mold, bacteria, fungi and other microbes. Particles drawn into the air ducts also pass through fiberglass filters and infiltrate into HVAC equipment, undermining the performance and energy efficiency of these systems. That can lead to higher repair and maintenance costs, and shorter service life in the long run. Air duct cleaning is a proactive solution to these problems. It can enhance indoor air quality, improve overall air circulation, eliminate built-up dirt and contaminants, and extend the life of heating and cooling systems.
