Thank you John Fay for your promptness to our Battery inquiry. You were fast, efficient and answered all questions I had. You made all you said and did very easy for my understanding. Thank you Guarduan for sending John our way!
Response from the owner:Thank you for your thoughtful feedback, Joyce! We're happy to hear that John was quick, helpful and made everything easy to understand. Thank you for choosing Guardian!

Tim Kapottos deserves more than 5 stars for work “above and beyond” upgrading my Guardian alarm system in the fall of 2025. He is an expert technician, a great problem solver and a genuinely nice person. The upgrades were expected to be relatively simple, but turned out to be more complex. Tim had to solve a number of unexpected problems to complete the work, and he worked methodically to solve each one. He also took the time to explain what was happening. The next time I need a Guardian technician, I hope it’s Tim (or someone he trained).

Natalie in sales was beyond amazing! Usually when you call big companies you get a robot or someone who seems like they really don’t care. Natalie was so personable and helped my husband get everything in order. If you want a company that you can talk to REAL, local people who care, use guardian
Response from the owner:Thank you for the amazing feedback, Charlotte! WE're so glad to hear that Natalie provided such a personable and caring experience. Our team takes pride in offering real, local support, and it's wonderful to know that came through. We'll be sure to share your kind words with her!

I had my alarm system put today. The technician Griff was AWESOME. He took his time walking me through using the alarm panel and the mobile app.
Response from the owner:Thank you for your great feedback, Lora! We're so glad to hear Griff provided an awesome experience and took the time to walk you through your alarm panel and mobile app. We'll be sure to pass along your kind words!

Justin was great!! Was thorough, discussed all details, patiently answered all my questions and left with a fully function, easy to operate, updated system. He was friendly and pleasant. If I had known it was this easy, I would have updated our system years ago. Highly recommended!!
Response from the owner:Thank you for the thoughtful review, Max! We're thrilled to hear Justin was thorough, patient and made the upgrade process so easy. It's great to know you're enjoying your upgraded system. We truly appreciate the recommendation!

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!

We recently had our doorbell and security system upgraded, and Justin did an outstanding job. He was punctual, professional, and extremely knowledgeable. He took the time to explain everything clearly, and made sure we were comfortable using the system before he left. We really appreciated his attention to detail. If you’re considering this company, ask for Justin, you won’t be disappointed.
Response from the owner:Thank you for sharing your experience, Sharon! It's great to hear that Justin made your doorbell and system upgrade experience smooth and stress-free. We'll be sure to share your positive feedback with him!
