Jeff Silverman did a great job installing our new Central Vac Unit. When we first moved into our home, I wanted someone to look at our system and tell me if it was in good shape. I found Jeff on Yelp and he came to our home, free of charge, to analyze our unit and give me a few tips. He said if the unit stops working, to call him again! After 2 1/2 years, our 30+ year old unit finally conked out and Jeff replaced it with a powerful and quiet unit. Not only did Jeff complete the installation around my schedule, he was clean and pleasant. He took the time to check the entire system and explained how the new system worked. I appreciate all his efforts and great attitude. Our new system has a 10 year warranty and works great. I would highly recommend Alarming Security and Jeff Silverman.
