I installed an alarm system with AAI 10 years ago at my previous home. I have now moved to a new home, and even though it already had a system, I have asked AAI to modernise it and take over the contract. I had, and still have, tremendous experience with AAI, I wouldn't change them for anyone. They are so professional, reliable, and one of the best customer services I have ever dealt with. I very highly recommend for anyone looking to install a system, or simply have AAI take over annual service.
