We have a very complicated, audiovisual smart house and it is close to ten years old. Paul from Automation and Entertainment Inc. had come in and had to figure out something as simple as cables, but our system is very very complicated. He had to dissect it to make it work. He stuck around and stayed longer than he planned to, and would stop by sometimes to make sure things were working on a timely basis. It was really difficult, but he never complained. Automation and Entertainment Inc. did a phenomenal job!!
