I signed up with Frase And then Guardian bought them. When I finally reached out To them to fix some issues, they have been completely responsive and John their technician has been amazing! He stayed from 8 AM until past 6 pm putting up my cameras and fixing my alarm system And was genuinely helpful, kind, and patient the entire time! In the same age where Customer Service tends to be so poor he was Absolutely phenomenal!!
Response from the owner:Thank you for sharing your experience, Suparana. We're happy to hear that you felt supported during the transition with Guardian and that John provided such patient, knowledgeable and dedicated service while getting your cameras and alarm system fully taken care of. We appreciate your continued trust and kind words!
My experience with Tony, the Manager was impressive. He had to work through some previous missteps in communication with others to resolve any issues or concerns on my end. It's rare to find such an effective manager anywhere these days.
Tim K upgraded my existing alarm system and added cameras.
He was prompt, professional, knowledgeable and very accommodating and open when I asked for a change in location of the monitoring screen. He made sure I understood everything and asked if I had any further questions. I was delighted to find such an expert and would highly recommend requesting Tim K. if you choose Guardian alarm which I also highly recommend as a company.
Response from the owner:Thank you for your thoughtful and detailed review, Laura! We're so glad to hear Tony was able to step in and effectively resolve your concerns, and that Tim provided such a professional and accommodating installation experience. It's great to know he took the time to ensure everything was clearly explained and tailored to your preferences. We truly appreciate your recommendation and your trust in Guardian!
I switched from a well known alarm company after 20 plus years. Was not there when I needed them after family safety was compromised. Slow response.
Went with local company serving Michigan and Ohio. Mitchell and Travis and other employee did an excellent job installing equipment and explaining how to use it. Wish I changed companies sooner. I highly recommend Guardian Alarm.
Just wanted to share that our Guardian Alarm system install team Michael, TJ and Cameron were all outstanding. The crew had to come out twice because the extremely cold weather initially posed a problem. Michael was so thorough with all the details of our installation and made sure our questions were answered. TJ and Michael also made sure that we were okay with camera positions and alarm device placement before they permanently installed them. They truly worked with us every step of the way and provided great customer service.
Response from the owner:Thank you for such thoughtful feedback, Lori! It's so great to hear that Michael, TJ and Cameron provided outstanding service throughout your installation, even with the challenges of cold weather. We truly appreciate your kind words about our team!
