After many years, I had to terminate my relationship with The Alarm Co, unfortunately. Truth be told, I was unhappy with their service for many years prior--in my opinion, their fees are high compared to other companies (like ADT, for example), they do not take into account the size of your home for monitoring purposes (I live in an apartment that is under 1,000 sq feet with 5 security points--they charge the same monthly rate to me as my parents, who have a 3,400 sq ft home with several more security points), their billing seems to be somewhat disorganized (would receive bills several days after

We were in need of an upgrade on our alarm system. The previous installer never returned our phone calls or emails. After multiple frustrations, we searched for a company to assist us. Larry at the Alarm Company immediately returned our phone call. We scheduled an appointment and two excellent technicians arrived and within one hour our entire system was updated and functioning perfectly. They explained the operating updates and testing everything. I would recommend them to anyone. They are very professional, courteous, and stand by their work.

Right now Mike is here - I can not BELIEVE how amazing these guys are. Kenny led my initial install almost 4 years ago and I called in for a problem. Mike rushed over and helped debug an issue that was NOT a result of their service. SERIOUS...just WOW.

The Alarm Company was the best when I first needed them over 30 years ago, and they still are. I can always count on them.
