I purchased a built-in vacuum system for my townhouse at the home show, and my dad was going to install it for me. When he got looking at the walls/joists, etc, he decided it was more than he had time to complete, so we asked the retailer to install the system also. The installer was neat, respectful, asked for my input on outlet locations, etc. I was very happy with the salespeople and the installer and the rate they charged for the install was very fair.
