Recently, Indoor air quality has become a great concern due to respiratory related medical complications and improvements in research technology. Such a concern, the Environmental Protection Agency designated poor indoor air quality as the fourth largest threat in the United States.

Air duct cleaning promotes a healthy work environment for employees and a comfortable environment for clients. Cleaning duct systems is particularly beneficial to patrons or employees suffering from allergies. Cleaning air ducts decreases pathogens and irritant particles from unwanted areas.

Our cleaning procedures and guidelines are in accordance with the National Air Duct Cleaners Association (NADCA). NADCA provides consumers with information for selecting a reputable firm. We are designated a certified firm of NADCA. Also, our company staffs ASCS technicians. These technicians demonstrate comprehensive knowledge and thorough understanding of heating, ventilation, and air conditioning system cleaning by passing the NADCA certification examination. 

NADCA recognizes the “Source Removal” method as the only acceptable procedure to properly clean and decontaminate air duct systems. Source Removal is also known as Mechanical Cleaning, which is physical removal of contaminants and debris not intended to be present on internal HVAC surfaces. In extenuating circumstances, Air Filtration Devices (AFDs) are used to collect particles, especially biological, from the air within living area. An AFD is a portable self-contained blower assembly designed to move a defined volume of air through a series of filters, generally HEPA, then air is re-circulated. HEPA filters have a filtration efficiency of at least 99.97% at 0.3 micron-sized particles.

Our technicians use industry-leading technology in the form of equipment and methodology to clean HVAC systems. The process of eliminating contaminants begins by sealing all registers (vents) and returns. Then, technicians remove contaminants from the HVAC system by administering negative pressure (vacuum pressure) to the duct system in order to control and pull contaminate particles to a specific exit for collection. Agitation from specialized brushes aides the collection process. The specialized brushes are fed through the duct to break up stubborn particles attached to the interior of the duct. Finally, we clean and re-attach vents.


Duct system cleaning methodology can vary due to system age, construction materials, and region located. We consider all variables to ensure HVAC systems are cleaned and restored in a safe, efficient manner. Air duct cleaning is recommended every 4-5 years for average buildings.

We are dedicated to provide our clients with the Ultimate Service Experience. We can offer our clients video inspection to determine when the duct system requires service.
