Professional, Experienced & NADCA-Certified

As a small business, our duct cleaning crew has strong past performance working on large-scale projects for the U.S. Army Corps of Engineers (USACE), in addition to the Naval Facilities Engineering Command (NAVFAC) and the U.S. Department of Veterans Affairs (VA).

In 2019, we were awarded prime contract W9128F19P0143 with the USACE Omaha District to perform asbestos and heavy metals dust cleaning at the Fort Randall Dam, a hydropower dam in Pickstown, S.D.

In addition, our crews are certified by the National Air Duct Cleaners Association (NADCA).

Our inspection process includes viewing representative surfaces in the HVAC system with fiberoptic borescopes, video cables, robotics and/or still photography to view and report on suspected areas of contamination.

We work with a network of HVAC and IAQ industry professionals in fields such as Industrial Hygiene and Building Science.

We assist our clients in identifying and solving contamination, internal lining, odor and cleanliness issues.
