Simmco Inc.

I got these folks' names through word of mouth, and was a bit concerned due to their small number of reviews here, but I had nothing to worry about. Although they arrived slightly late due to traffic, they did an excellent job: friendly, professional, answering all questions before and during the job. First rate equipment, from the huge truck to the pneumatic "spiders" that whipped around and cleaned the inside of the ducts. They even will take and show you before/After photos of the ducts, but just be sure to ask for this before they start.
