March 28, 2008 I researched a number of other Duct Cleaning companies in Sacramento and Roseville, before selecting California Air Duct Cleaning. When I spoke with the owner of California Air Duct Cleaning, Randy Kienast, I was impressed with the level of detail he gave to the process. I was conviced that he would do a moch more thorough job for us. Randy did not disappoint! When he showed me the ducts “before and after” cleaning – it was impressive! Some companies offered to clean out ducts for $100 in 1-2 hours. I don’t see how these companies could do the complete cleaning of the entire system that is required. Tandy takes the time to do the detailed cleaning that you need. Thanks, Randy!
