Comcast Self Installation

Comcast will normally install cable boxes for free for new customers and customers who've moved to a new location. If you want to hook up another box in your home, Comcast will typically charge you an installation fee. You can avoid those charges by connecting any additional boxes yourself. To install a new box, you must have a working cable outlet nearby. You will also need some additional cables to connect the cable box to your television set.
