"I have always trusted ADT to protect my home and family. They are conscientious and courteous. I have recommended them to my family, friends and neighbors. 

They offer you the basic protection plan as well as the Medic-alert console. With this option they provide a feature in which they test your system monthly so that they could hear you in case of a medical emergency. I had to use them on one occasion in which they had to contact emergency services to get me an ambulance to get to the hospital. They literally saved my life."

"We had new windows installed, scheduled an appointment the next day to reinstall our sensors. ADT technician Matt **, the most courteous and knowledgeable technician I've ever met...

also reviewed and checked our entire system, ensuring that every facet of it operated correctly. When he finished, he thoroughly briefed us. If I ever need an ADT technician again, I want Matt **! Great ADT Service!"
