Over 90 years of trusted service

I recently had my security installed by Tim K from Guardian Alarm, and I could not be more impressed with the entire experience. From start to finish, Tim was professional, knowledgeable, and incredibly personable. He took the time to understand exactly what I needed, explained every option clearly, and made sure I felt completely comfortable with the system before he left.

What stood out most was Tim’s genuine care and attention. He didn’t treat the installation like just another appointment - he treated it like an opportunity to make sure my home and family were protected. His patience and expertise made the whole process smooth and stress-free

If you’re considering a security system, I highly recommend asking for Tim.
Dave went above and beyond! Extremely polite and helpful!
John is patient, thorough, thoughtful. The job involved an unexpected solution but he was calm, confident and professional throughout.
Enjoyed sharing stories with him, too!
We been getting a lot up upgrades to our cameras an system an doorbell the technician tj has been awesome! Very professional an calm though the whole process would def recommend him to anyone! This upcoming week we're getting new deadbolt locks for our front door very excited for TJ to do that job as well. He's very friendly and kind always on time for appointments. !
Tech TJ did an excellent job on rehooking up all cameras and explaining what happened to prevent in the future
Mr. T J did an excellent job. I am very pleased. Thank you.
We have had our alarm system for 3 weeks now and are very satisfied with it. We liked the guardian system because it did not require a lot of wiring and drilling, it is a very clean system which can easily cover every room in the house. It also has easy access options from the panel, your cell phone or laptop.

It took a while before we had all the settings adjusted to our needs, it would have been nice if we were given an owners manual at the beginning to help us with the various options. During the installation, you really don't know what you want, but after a couple of days of hearing "garage door open" you want to silence that! They have very good technical customer service which helped me through these options and advised where I would download the owners manual (it was too large to attach to an email).

TJ, the gentleman who installed our system was also very helpful, coming out to our home after hours to fix a doorbell chime not working and promptly returning all calls made to him. Our salesperson, Angela, was also very friendly and helpful!
T J was absolutely amazing and very thorough explaining everything to me. So great.
John Fey is great! He's enthusiastic and professional. He does an excellent job and is friendly and shows that he takes pride in his work and wants the customers to be satisfied with the company.
TJ was really knowledgeable. Very friendly and just a great experience
Thank you for sending him out to my ho.e
TJ was amazing! He was timely, efficient and thorough in the set up of our new keypads.
John Fay was an Excellent service provider. Our home has many similar descriptive rooms so it’s not easy to determine the names given to each installed alarm component and I was of little help. He looked for malfunctioning alarms and found each one bringing each to the alarm box to match numbers to make sure it was correct. Not only did I guide him in the wrong direction, but he kept his same upbeat demeanor with much kindness and patience while troubleshooting all the alarms. I couldn’t ask for a better service representative of Guardian Alarm. John was the best!
John fay, was extremely informative about my system able anwering my questions.
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.
TJ was such a help in explaining things so I could understand. He answered ALL my questions. Great personality and very professional.
Tim came and installed monitors and updated our alarm system. Tim is very knowledgeable, professional and friendly. I would definitely recommend Guardian to anyone.
I couldn't have asked for a better technician. Rudy was very knowledgeable respectful of my home and very nice spectrum is lucky to have a worker like that. He explained everything clearly and kept asking if I had any other questions. They need more workers like him. The only disappointment I had was the equipment they use. The wireless contacts they use are large plastic and are unpleasant to look at.
David was very knowledgeable about our system which is quite old and fixed the issue quickly.
Anthony Hart went above & beyond answering any and all questions we had. Everything was done smoothly and as said. Can't be happier with the friendly & professional service. Will be recommending him & guardian to friends & family.
TJ from Guardian Alarm was absolutely professional and did a great job on our project. Would definitely use again and recommend.
Tim did a fantastic job upgrading my system from ADT. Very friendly and knowledgeable. Highly recommended!
Great company. Great reliable service. I’ve been a customer for many years and can’t think of anyone else I’d go with. John F came to our home today. Very friendly, efficient, answered all our questions.
John Fay was the technician who came to our home today. Everything he did was absolutely perfect. He set up the contacts and answered all of our questions. I highly recommend him if you need support from Guardian Alarm
Our technician, TJ, was extremely knowledgeable and did a great job... I would recommend him, and Guardian without hesitation...excellent work and service!
Justin V. Is a professional. Courteous and knowledgeable technician. It was a pleasure having him in my home.
John, the technician, did an exceptional job at resolving our system failings. He really got our lights back on!
From the sales person to the person that installed it and any phone questions that I have asked. The service has been fantastic.I’m
⭐️⭐️⭐️⭐️⭐️ 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!
TJ did a great job installing my Smoke & Carbon Monoxide detectors, along with updating my system.
TJ was right on time for our appointment, you could almost set your watch by him.

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.
We've been with Guardian for a long time and they have always given us excellent service!
Getting my smoke detector and fire alarm system installed for my mental health group home facility was definitely a 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…..😉

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
