We have had ADS protect our home for over 14 years. They are far superior to the two companies that we had before we moved to the Chicago suburbs. They have always contacted us in less than a minute when we have accidentally set off our alarm. Recently they contacted us to advise that one of our batteries was weak and needed replacement as they have done a couple of times before. The technician, Jose arrived as promised and quickly diagnosed what the real problem. He ended up replacing both of batteries in our 2 controllers and replaced one of the controllers completely as an upgrade. He was very courteous and cleaned up completely before leaving. Our radio backup has been great when we have had power failures and phone line problems.

We have had a great experience with Alarm Detection Systems. We have been a customer for years. Alarm Detection Systems really does care about its customers. Recently our carbon monoxide detector needed to be replaced. Our technician, Russ, offered to change all of our smoke and sensor batteries while in our home too. Russ and Alarm Detection Systems provides very thoughtful and professional service.

Bigger isn't always better. Thinking largest market share holder might be the way to go when upgrading our system, we did. However and fortunately, we weren't locked in because I cancelled the service on the last day possible. One of the new smoke detectors was faulty. Information on equipment needed wasn't accurate. I was dealing with a provider. Customer service was dismal. Despite being offered a substantial savings to remain with them, we chose ADS instead. Want the most responsive, best personal care and customer service? Use ADS! Should you have an issue, ADS will take care of you.We continue to be pleased with the excellent customer service, tech support and technicians. Thanks, ADS!

Incompetent. We had a mandatory inspection in May. I know where my alarms are and had to direct them to each of them. We made sure they tested all the correct alarms before they left and I was still given a notice saying I had to be present during my holiday weekend to be here for them to get what they missed. Please train your employees correctly so this doesn’t have to happen again.

Suggestion what could get better….Try some Customer Service. We have been a customer for over ten years, and I think ADS has become complacent. Left two messages and no one called me back. After calling multiple times finally reach someone. I got the sense I was interrupting her day. My overall experience was not good on a scale of 1 to 10 they score a “2”. I could go on and on but will stop here. if anyone wants my opinion please reach out. I’m pretty sure ADS is not the only fire monitoring and inspection company in Naperville.

ADS is a local company that we have used for fifteen years or so now. In that time we have had maybe a dozen alarms (all accidental, thankfully) and their response has always been perfect! Their service is excellent. They do all of the work themselves, no subcontractors to worry about. We have always been more than satisfied and recommend this company to anyone contemplating installing a full service alarm system.
