Greg G.
Guardian Alarm has been our alarm service provider for roughly 19 years. We wanted to add video to our system. We reached out to them and were able to set up an appointment with Matt (Residential Security Consultant) immediately. We discussed what we were trying to accomplish with Matt and he helped us craft a plan to upgrade and add video to our system and scheduled the install for the following week. TJ arrived at the scheduled time and did the install in a matter of hours. He was very knowledgeable and worked with us to set up the system and phone application just the way we wanted it. The experience of working with Guardian to upgrade and update our system makes us very confident we are working with the right security system provider. We would highly recommend them to others for residential security services.

Patti L.
I recently had a Guardian Alarm system installed in my home. Lauren Mickens was the rep that got me started on the phone by explaining what would be the best for my home. Two days later, TJ, the Alarm Technician, came to install the system. He had a great sense of humor and explained how everything worked in great detail. Installation took less than 2 hours. The greatest benefit that I find that is so helpful to me is having the app on my phone so that I can arm/disarm the system from wherever I am.

Scott and Paul are the absolute best! They are the type of people you want representing your company. Scott was my sales rep and he was more like a really good friend and not just some sales guy. He took the time to go over all of the options that were a available to me and also breaking it all down. Paul came to my home to install the system and he was like a brother or good friend of the family which was awesome! He too went that extra mile to make sure I was covered and understood every. They both left a lasting impression on me that led me to say that I’m a life long customer now and I am. Thanks guys for making the experience one to remember.
Michelle P.
Everything went smooth and it’s really easy to use. No surprises just great security.
Tresae A.
Guardian customer service called me back twice to get my matter resolved instead of me having to keep calling back.
Cindy B.
Working with this company is awesome. We have had this alarm system many years and recently upgraded to the newest camera systems. We have worked through all the technical issues of network extenders etc. They have exceeded my expectations always on time and very helpful. Took the time to explain all the features of the system. A great shout out to A.J, Arman and Jose. Few days later we were refining our system and Imani was soooooo good. She helped us understand and never left us until all was settled we appreciate her patience and knowledge of the system. Highly recommend guardian alarm.
Sara R.
We recently had some upgrades done to our Guardian Alarm system. Justin, the installer, was very professional, knowledgeable, patient, and efficient. After the installation, he took time to carefully explain how all the new equipment, cameras, and new control panel worked. If you are looking for a security system, we recommend Guardian Alarm with Justin as the installer.
Lori M.
I was impressed from start to finish. Scott was wonderful to work with to help me figure out best options for my home. And Justin the installer was a pleasure as well. He made me feel comfortable and was just great with my three dogs. That is something I worry about and he was fantastic!
Robert A.
Scott was absolutely fantastic, very professional. He walked us through our system and gave excellent recommendations for upgrades. We have been a customer of Guardian Alarm for years and will continue to be one of their customers, largely due to their great service and awesome employees. Thank you
