“HD Systems Integration, Inc. are the experts you want to have when it comes to in-home entertainment. They understood our project immediately and provided details of plans and costs to fit my budget. I have rarely had the opportunity to work with such a positive and capable organization. I find that this excellence and approach can only come from a positive and forward facing leader. Great service with minimal interruptions. Additionally; for what is perceived as a small organization, the service is the highest level. It was one stop shopping for all of my hardware needs.”

Steven M Mitus

“It has been great working with a real professional who took the time to understand our needs. We had a problem with our existing system and they came out right away to troubleshoot the problem, even though it wasn’t a system they sold. We recommend their services to anyone that wants the job done right.”

Alan Ferrigno

“Jay completed several projects for us including the installation of a theater room with projector in our basement, an indoor/outdoor sound system and a 50-inch plasma TV. Jay was incredibly knowledgeable and professional in every aspect of the project. His workmanship was impeccable and he was always on time and completed the work on schedule. He responded to issues or problems, which were due to faulty components, in a very timely manner. We have the utmost respect for him as a person and professional. We will definitely use him again for future home entertainment projects and recommended him without hesitation to anyone looking to set up a home theater.”

Michael Plevyak

“Jay installed our security system for our warehouse. He did everything that we needed and made us aware of things that we weren’t aware of so that we would get the most out of our system. He was very professional and courteous. He cleaned up after himself like a white glove caterer. Whenever I had a question he gave me an immediate and easy to understand answer. I would recommend HD Systems Integration, Inc. to anyone. Their prices are fantastic and knowledge and capabilities are far above anyone that I have used in the past. HD Systems Integration is the only one I’ll use in the future.”
