Full duct cleaning on two storey, two furnace home. Exceptional work by Michael and efficient, enjoyable interaction with Karen in booking. Ducts cleaned at least three times previously, yet Michael was able to remove large amounts of original construction debris, kids toys, and other filth that had been there for over 30 years — all missed by earlier “reputable” cleaners. Also removed and cleaned both furnace fans. Marked improvement in air quality in home, less dusting of surfaces, and the furnaces seem to be working more quietly and more efficiently. Gold standard duct cleaning, highly recommended. Oh, by the way, very reasonable cost for the quality of service provided.
