“Dave did work for us three and a half years ago. He is full service—he mounted the flat screen TVs, set up all the speakers, ran all the lasers, ran the wires in the attic, and really provided an excellent system for us. He knew what worked well without overspending. His quality of work is fantastic and the level of his integrity is even more impressive. We remodeled our whole house during this time and dealt with 10 contractors; he was at the top of the list.” Scott L., Gold River

“Dave and CSV were a pleasure to work with in the design and installation of our audio, visual, and alarm needs at our new house.” Sam M., Sacramento, CA

‘We had Dave of CSV Systems install a security and fire protection system for us in 2010. Dave was very forthright and did not try to sell us anything more than what we wanted the system to provide in the way of security and fire protection. If we had a question or the system needed to be checked, he always got back to us promptly and either answered our question or made sure the system was operating optimally.” Dr. Margaret and Ron R., Auburn

“I have hired Dave for electrical work for 20 years. He is very personable, dependable, and trustworthy. For all electrical work, he is the only guy I will hire. He has installed an alarm for our house, a motion detector, and done rewiring inside.” Ron M., Gold River
