There are several ways clean an HVAC system. Recommended cleaning methods employ "Source Removal," the mechanical cleaning of system components to remove dirt and debris. Source removal methods employ vacuum units, compressed air, mechanical and hand brushes, and other tools to loosen dirt and debris and convey it to a containment device for proper disposal.

Source removal requires two key elements to be effective. The first element is a means of agitating the dust and debris within the HVAC system. The second element is the extraction of contaminants from the HVAC system. Remova: methods must be capable >/f removing the foreign m& erial to the levels specified within industry standards.

Air duct Jeaning services have beer, available since the early 1900s. By the early 1970s, hundreds of air duct cleaning companies were thriving in America. The problem, however, was that many of these

companies were utilizing inferior methods of cleaning. Often they applied chemical encapsulants or dust abatement products over contaminants In air ducts to restrict the movemen’ of these particles and render them "harmless" to build.ng occupants. However, msny such products were not prover safe for use In air handling systems.

In February of 1989, a group of air duct cleaning professionals banded together to help educated the public about the need for properly performed HVAC system cleaning services. They formed the National Air Duct Cleaners Association (NADCA), and made it their goal to promote Source Removal methods of HVAC system cleaning.

Today, NADCA is represented throughout the United States, and also has a substantial international membership. NADCA's involvement in programs held by the U.S. EPA, American Society of Heating, Refrigeration and Air-conditioning Engineers (ASHRAE), National Coalition on Indoor Air Quality (NCIAQ), and other environmentally conscious public and private sector organizations will help the association continue to be the leading authority in HVAC system cleaning.

Introduction to HVAC System Cleaning Services-A Guideline for Commercial Consumers is a comprehensive overview of HVAC system cleaning. Chapters include contaminants, indoor air quality, site preparation, equipment, chemicals, safety, and much more.
