Today, 11/12/25, Guardian technician John Fay came to my home to determine why my new wireless doorbell could not connect to my WiFi system. The problem started 11/6/25, when I recharged the battery for the first time and it did not reconnect to the WiFi system. I called Guardian Alarm technical support and worked with Andre for 30 minutes but the doorbell could not connect. He scheduled first available appointment for 11/12, noon to 4 pm window. John Fay called ahead and arrived at 2:25 as estimated. John updated the firmware and then connected the doorbell with no problem. He was professional and efficient, patiently answered my questions and provided tips on setting the doorbell for best use in my location. I will be asking for John Fay if I need any service calls in the future. I am pleased with service and quality of equipment Guardian Alarm provides.
Response from the owner:Thank you for being a valued Guardian customer for 15 years, Catherine. We're thrilled to hear that Kara and Michael made your system update seamless and provided clear, professional support from start to finish. Thank you for recommending Guardian Alarm!

TJ was very professional and knowledgeable of my upgrade. He went through the process of showing me how to operate my new system and explained how it works. Also he was very respectful enough to remove his shoes when he entered my home and I would very much like to thank him for showing me that he cares.
Thank you again!
