We had an absolutely fantastic experience with Tim! From the moment he arrived, he was professional, punctual, and incredibly knowledgeable.
The main objective was the installation and testing of our new security panel, which he handled quickly and efficiently. What truly sets this service apart, however, was the attention to detail with the existing components. Tim took the time to meticulously go through each sensor across the house—door contacts, window sensors, and motion detectors—to make sure they were all correctly configured and communicating flawlessly with the new panel.
HIs thoroughness gave us complete peace of mind, knowing that the entire system, new and old, is working exactly as expected. He also patiently answered all my questions and made sure I understood how to operate the new system before leaving. If you need reliable, expert security alarm system service, look no further. Highly recommend!
He introduced himself and was very courteous throughout the whole encounter, at sometimes humorous, his demeanor and attitude towards his work added a little personality and personal concerns for our satisfaction.
He showed great confidence and appeared to be very knowledge and experience and what he was doing , leaving us with no doubt that he would get the job done correctly.
TJ was thorough and made sure everything was working properly before he left, he even gave us his personal cell number and made it clear that we contact him directly with any future issues.
All I can say is that, if TJ is a representation of Guardian’s support function, I don’t see why we would trust our home security to anyone else.
Great job.
The installers Anthony and Dave were very helpful and great at what they do.
I had the pleasure of working with Selena who overlooked the details and was able to work out Some minor issues that we came across.
Keith, their boss was a pleasure to work with and even was able to give me options for the down payment and balance due after installation.
Overall, I appreciate working with Guardian Alarm and would recommend them for any project big or small.
Thank you guys for your time and patience. Im not the easiest costumer for sure…..😉

I highly request him by name.
I had no disappointments and high expectations , and he serviced everything properly.
Don't be ALARMED if Tim shows up on time and in uniform.
He's professional

Yesterday, 9/26/2025, I had the main panel updated to the current technology because the existing panel was failing and the manufacturer no longer supported that model. All of the monitor devices in place were successfully transferred to the new unit and are working. A new video doorbell was added and is a clear improvement on the previous product.
I received support from the local Guardian Alarm office, Kara Pichichero in the office and Michael Roseblossom, the technician who installed the new equipment. The service was scheduled in reasonable time, completed promptly, and he left the house in good order. Michael walked me through the setup and explained how to use the new functions, and let me know I can contact Guardian for any additional questions that arise.
I am pleased with the service and equipment. I can recommend Guardian Alarm as a good choice for monitored home security.
