"One of the doors in my old house took longer than expected but all three are now working or have been replaced. Brian was easy to contact and available within a couple weeks."

"Last weekend had someone pry our side door open to our exterior garage and the ADT door sensor picked it up immediately. The alarm siren was loud and scared the person off. Someone from the response center called within 30 seconds. We’re fortunate that the security system did what it is supposed to. Feels like we made the right call going with an ADT security system."

"I returned home from a conference to discover my boiler leaking, leaving me without heat or hot water and concerned about potential damage. Steve, a highly skilled and friendly technician, clearly explained the scope of work and costs before getting started. He completed the repairs within a few hours, and the system is now working better than ever. I feel secure in my home again. Excellent work and a great overall experience."

"The job went very smoothly. The tech ran a bit late, but he called to say so. He installed a keypad by the front door and assessed the house for security. He suggested, since there are several casement windows in the living room and adjoining dining room that a breaking glass sensor would work better and be more cost-effective than alarming all the windows. He did alarm a door that the previous company (inherited when we bought the house twenty-three years ago) had not considered significant. I feel safer with the current sensor choices than the ones I had before.
He took the time to make sure I knew how to use the system, so I am very pleased with the service. My one caveat: I was told that the motion sensor would not register my smaller pets (two cats) because they weigh under forty pounds. They must have set off the sensor, though, because the police responded. The system certainly alerts the authorities, but that motion sensor is very sensitive!

"That's the name I am vaguely familiar with; it's a home security company that is license to ADT franchise or dealer if I am correct. They were very good. They were prompt; they were quality. The individuals move their business. They were very timely and it was a good experience."

"Protect America Alarm Systems are wireless home security systems that are so advanced and yet uncomplicated that the consumer can install all components to the system themselves. Tech support is provided which makes installation easy and very user friendly. The system is monitored and response to alarm signal is quick and nearly immediate. ( I accidentally set it off a couple times having forgotten that it was set when we left home). I've had a couple different systems in my homes over the years which were "professionally" installed; one was wired the other wireless. I install this myself with the help of tech support, I'm 65years old in good health but of course not as agile as I was a few years ago, but this system was a piece of cake for me to install. Every access to my home has been covered as well as some interior sensors. All of which have functioned flawlessly from day one!
