“My wife and I had our system installed about 2 years ago in early 2016. David Mueller was our sales consultant and he helped us get the exact system we needed. His customer service was amazing, just like everyone else we have dealt with at Alarm Engineering. He made sure that we did not get more than we need or not enough. I would and do recommend Alarm Engineering to everyone.” -Matthew in Georgetown, DE
