NADCA Residential Air Duct Cleaning & IAQ Impact
A nine-home field study evaluated the impact of mechanical air duct cleaning (ADC) methods on indoor air quality (IAQ) and system performance. ADC services were provided by the National Air Duct Cleaners Association (NADCA); only mechanical ADC methods were assessed. Surface sampling showed mechanical ADC removed adhered dust and dirt. System performance measurements suggested positive effects: supply air rates increased between 4% and 32% in eight houses, and return air flow rates increased 14% and 38% in two houses.

HVAC Duct Cleaning Effectiveness for Indoor Air Quality
This study reviewed three commercial HVAC duct cleaning procedures to determine their effectiveness in reducing airborne particulate matter and viable bioaerosols in residential homes. Post-cleaning bioaerosol concentrations, measured two days after treatment, were lower than pre-cleaning levels, indicating the procedures reduced contaminants to some extent. Homes treated with the Air Sweep procedure showed the largest reduction in bioaerosol concentration among the methods evaluated.
