Decades of dust and debris in original sheet metal trunks
Why it happens here
Most homes in the historic district have never had their ducts cleaned, and the original sheet metal trunks have been collecting dust since the mid-20th century. Utah Valley's dry, dusty air adds to the load every year, and the debris bonds to the metal over time.
Our approach
We use a rotary brush duct cleaning machine and an air compressor with a flexible whip to break the bonded layer loose, then extract it with a HEPA vacuum and negative air machine. On a typical job we remove 4 to 7 pounds of debris.
