⭐️⭐️⭐️⭐️⭐️ Exceptional Service and Expertise!
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!
Response from the owner:Thank you for such a thoughtful review, David! We're so glad to hear that our team provided such excellent service. We appreciate you taking the time to share your positive experience!
I am very happy with Guardian Alarm of Columbus. I had a theft outside of my home and contacted them the day before Christmas Eve- 12/23/24. The immediate response was wonderful and the morning of December 24, 2024, cameras were installed outside adding to my inhouse security. Thank you, Mark Howells, my salesperson and the terrific young man who drove from Dayton, Ohio and installed them. I have had other security companies, but Guardian Alarm is the very best.
Response from the owner:Thank you so much for your kind words! We're thrilled to hear you had a great experience.
Tim totally exceeded my expectations on the recent upgrade of our ancient security system. Even though he was unprepared to encounter such an old system, he was undaunted and cheerfully came up with a solution on the spot. A pleasure working with such a kind, honest and knowledgeable professional. Highly recommended.
