I was referred to Hitek Built-In Systems from a colleague who talked very highly of the owner Kris and the great value of his services. When I spoke with Kris he was professional and knowledgeable. After her explained in detail to me the quality and benefits of many products I purchased a set of central vacuum accessories from him at a fair and reasonable price that was less than many competitors. Several months later I had issues with my central vacuum unit that came with my house and he again took the time to explain and troubleshoot with me over the telephone. His great instructions and patience save me the cost of a service call. He could have easily just book an appointment and charged me, but he honestly wanted to provide excellent customer service.
