I do a lot of research before contracting out a job. To be honest I couldn't see much of a difference on the surface between The Duct Cleaning Specialists and some other companies (many of them located closer to my home than TDCS). The major difference I saw was the enormous amount of great reviews on HomeStars. I decided to go with TDCS and Paul (owner) arrived with a worker and got the job done. Although my ducts were in pretty good shape, they educated me on proper cleaning techniques, helped redistribute the airflow throughout my home and maximized efficiency by closing some seams in my return vent that, unbeknownst to me, were ripped open by previous owner.
The other half that impressed me regarding this company was the impeccable service, and although they've reached out to me to report my experience on HomeStars, this review and their service is legit. Job well done boys.
