Ackerman Security service was wonderful. When I called to schedule my appointment the lady was very nice and informative. She let me know that the gentleman would call before he arrived. David was on time and very knowledgeable about our system. He did not try to push me to buy service that I did not need. When the tech arrived he was on time. I was not at the home, because we were moving and I was at the other house. He waited until I arrived. I thought that was amazing!I would recommend Ackerman security to anyone looking to install an alarm system or change providers. Thanks David!
