After unfortunately having a central vacuum system installed by someone who did not do it properly, dealing with Jeff Silverman was a breath of fresh air. I was referred to Alarming Security by Nutone as I was having issues with the vacuum. Jeff immediately answered the phone and was able to answer my questions. As my issue was more complicated than could be answered completely over the phone, he came right over and consulted. He was very patient and went above and beyond the call of duty. Jeff helped me to actually order parts online and get the best deal possible and said he would be available to assist me in the future. I highly recommend Alarming Security and Jeff Silverman and wish I had used them in the first place.
