While we may

While we may spend time and money on vacuums, dusters, even air cleaners for individual rooms,
one of the best ways we can immediately improve the indoor air quality in our homes is with air
duct cleaning and restoration. When making the decision to clean the air ducts in your home, it is
important to keep several factors in mind. One, does the company cleaning your air ducts conform
to accepted standards of cleaning? Namely, do they clean in accordance with NADCA Standard ASC-
2006? That standard states that in order to clean ductwork, the system must be placed under
negative air pressure and then physically agitated with cables and brushes and/or compressed air.
Some duct cleaning systems do not allow for this to take place. Some are not much more than a
glorified shop vacuum.
