Over 90 years of trusted security

We just upgraded our system with 3 years locked price. Very happy to far, we may even add carbon monoxide detectors and sump pump alarm. The technician, Griffin, was very knowledgeable, professional, and respectful. Explained everything in details on how to operate new keyboard, and set up.

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.

Eric was the best tech I have ever had at our home. He was incredibly thorough and professional. Very helpful in explaining what he was doing, never made me feel like I was bothering him.

We recently had Tim K. from Guardian Alarm visit our home for a thorough system check. He arrived punctually, exuded professionalism, and displayed a deep understanding of the security system he was working with. Tim took the time to explain each step of the installation process, providing detailed descriptions of how everything would function. He even offered personal tutorials on how to operate each component. We’ve consistently been satisfied with Guardian Alarm and highly recommend them to anyone looking for a reliable security system.

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!

We had a new security system installed today by Guardian. TJ did the installation. Super nice guy, very knowledgeable and thorough. I love the system and the app is great! Thank you TJ!!

Tim was so very helpful and courteous. He was a great guy and did a great job.

I needed assistance to refresh my panel because of a glitch… the representative was very attentive and prompt!! Thank you for correcting my problem so that I could secure my home using the panel!!

Tim K was out at our business today and got us all set up with a new alarm system. When he was done with the work, he took the time to go over how to arm and disarm the system and how to use the mobile app. It was very helpful. I recommend this service!

Very friendly and knowledgeable. Fast but thorough.

Gentleman who come to our house was very professional!He did amazing job!!Everything was on time! Great customer service!!Very recommended Guardian Alarm company!!

Tim was very quick and efficient and provided the best customer service I have experienced in a while!

Tim Kapottos did an exceptional job updating our system. He was conscientious, thorough, and explained everything very clearly. He provided truly outstanding customer service and it was a pleasure working with him and the Guardian team.

Took his time and made sure everything worked well and that we understood how to operate the system.

TJ did a fantastic job upgrading our system. He took the time to explain everything in detail, ensured we understood our new options, and performed a top-notch installation. He also followed up quickly with some questions we had afterwards. Highly recommended!

Sales team came out and inspected our home and recommended replacement security products that incorporated our existing hard wired sensors. Technicians were prompt, courteous and patient given some complexities in the installation requirements. All work was completed on the same day, tested and we were shown how to use the system.

Tim the installer was great! Super helpful, knowledgeable, and nice to work with.

Great experience from start to finish

Tim did a great job and he was very informative. Thanks a lot for your great service.

John H. was wonderful, patient and a professional. Our issue was resolved quickly!

Ive had Guardian for years; but, I took personal interest after a couple of life changing challenges. They came out, reviewed my system, we made a few tweaks. Customer service is great! I have the direct number for management, if needed.

Purchase and instalation went great! Very pleased with the system.

Tim Kapottos, my service technician was great during my installation. Friendly and very knowledgeable, very easy to understand. He is definitely a "keeper" employee!

John did a great job getting our monitor up and running quickly! This is the second time he has helped us, and each time he has been knowledgeable, efficient, and easy to work with. We truly appreciate his support.

Service via phone call to reconnect two keypads was excellent. The problem occurred after new routers were installed at my house.
The technician was very knowledgeable, patient, friendly, and kind.
The interaction took a long time … probably due to the fact that the technician was dealing with a non-techie grandmother.
My thanks to Roger!

Tony Tuggle was quick and thorough when fixing the motion sensor he found the issue explained it clearly and even caught another potential problem highly recommend

I had three doors replaced in my house and garage. I haven’t painted the trim yet but the alarm sensors had to be reinstalled. The service technician Mike did a great job. He was prompt, courteous and professional.
I couldn’t ask for better service.
Hopefully Mike gets some recognition for his fine work.

Tech was excellent, even cleaned up after he finished.

Tim was great !!! Thank you

Tim was great! Highly recommended

TJ was very friendly and professional. He installed my alarm and explained everything with patience. Guardian is the way to go for a home alarm system.

This gentleman was very professional from start to finish. Very acknowledgeable about the system and even helped me with my phone app! Guardian is very lucky to have him in their team! Thank you for your service Mr. Kiplin!

TJ was very kind and knowledgeable would recommend to anyone.

The service technician was very knowledgeable about the system. He investigated the cause of the trouble notifications and corrected the problem. He was very energetic and completely investigated the system to make sure everything was working correctly. He will be returning to replace some defective components.

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).

I got scammed by a home security company. they came with some new updated equipment fancy stuff and I wanted to try it. They told me that they will pay my final bill with my current provider which was guardian I had no problems with guardian home security I just like some of their equipment that they had they told me they would pay that last final bill not to worry when I agreed to go forward with the application I had to unlock my credit and unlock my credit card. And then, in that short period of time, the person the representative Who is at my home apply for a $6000 credit card that I did not OK and I did not approve. He lied to me about everything. I trusted the young man. They all came in from another state. I believe it was California. They were not originally from Ohio so after I cancel my subscription and had all the equipment recovered, I had no service I had no security. I felt naked, and I owe a final bill to close my account with guardian. I feel like a fool that was so stupid of me. Why did I regret it because being on a budget I just didn’t have the extra money laying around to pay a final bill, but the people are guardian understood they were always kind soft spoken never harsh or judging me. The woman I spoke to on the phone was very patient and I want them to take me back please take me back guardian they were good.

TJ came to my home and updated my alarm system . He was polite & professional and explained what he had completed. I would highly recommend TJ.

Tim was great, he explained how to operate the new unit very thoroughly, great customer service.

The representative was friendly and knowledgeable about our monitor. He was willing and able to answer all our questions for us to use our equipment to its fullest pitenti

Service man was great. Knowledgeable and sharp.
5 star service

Tim was knowledgeable, professional and clean

My process was not great but they made up for an error so that was good. Its hard to get a hold of someone for logging into the app which you need. Would recommend a more direct hotline for that. So they did make up for the mistake, which was good.

Tim was awesome! He was very knowledgeable and offered some great suggestions for me! He has an awesome spirit and a caring heart! Thanks, Tim for your help!!

Tim K. Did an exceptional job with my Guardian Alarm Service install. He is knowledgeable and professional. I feel secure.

Tim was very professional and thorough.

EXCELLENT! Patient! Attentive & knowledgable. Pleasure to work with. Recommend highly!!!!

TJ was awesome and very dedicated to helping me install my alarm system!

Tim kappottos handled and answer every question I had very professionally very respectful happy with all his work fast and helpful

TJ was an outstanding and friendly tech who came by to upgrade my system - he worked expediently and took the time to explain the new system functionality and what exactly he had done in terms of the installation. Been very satisfied with Guardian and their response time.

TJ was awesome. He was professional and got the work done quickly.

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.

Joe was a great technician. He answered all of our questions. And promptly solved out camera issues. Thank you once again!

We have been with Guardian Alarm since 1986. Overall we have been satisfied with their service. We have occasional equipment or service issues but they have always been responsive in getting things resolved. We have been using the Guardian Connect app for several years without issues.

They sent a few text messages through the week to notify appointment. Once the day of appointment was here, they called and confirmed the 1 to 2 hour window they were showing up. 30 minutes before they called to make sure we were still home and ready for their arrival. They showed up and fixed the problem within 10/20 minutes.

- great communication
- great service

Dennis I. came to install our system and he was fantastic. Showed up on time, was knowledgeable, and worked with us since we had to keep production running. As the appointment ended he even showed me a few tips on using the system that I was unaware of, it was great to realize what the “stay” mode meant, and that I could turn the chime on or off at will. Thank you Dennis and team!

I had the pleasure of having Tim Kopottos switch out my smoke detectors. He was very professional, kind, patient and knowledgeable. His knowledge and expertise allowed him to answer any questions I may have had before I could ask him.

He was extremely helpful and patient. Ryan did not leave until we totally understood how everything worked.
This was a great experience.
He is an excellent worker and represented your company as a true professional .

Dennis is great, please keep him on the team!

Great service and customer satisfaction

The service technician, Collin Kiplin, was prompt and professional. The required service (sensor repair) was adequately resolved. Thank you!

Great Company and Hubby and I are more than pleased!!!!!!

Guardian Alarm delivered excellent service from the very start. Professional, caring, and compassionate staff made the whole process smooth. I’m very pleased and would recommend this company anytime!

I had an outstanding experience with guardian installer Griff. Griff showed up on time, communicated clearly, and walked me through every step of the set up. Griff is knowledgeable, friendly, respectful and was patient with all my questions. Everything was installed neatly and tested thoroughly before he left. I feel confident and secure knowing the system was done right. I highly recommend Griff and guardian alarm. Griff is truly an asset to guardian alarm.

Dave went above and beyond! Extremely polite and helpful!

Home alarm. Price is reasonable, they act quickly when the alarm is activated & customer service is very good.

Big help by phone revealing we need a new control pad. Awaiting sales call for a replacement.

He was amazing! Has amazing service and patience and explained everything to us while also answering any questions we had!

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.

I had new cameras installed at my resident, and the tech Mitchell was professional and explained in detail about the installed. Exceptional!

We had a great experience with Mitchell from Guardian. He was professional, patient, and explained everything clearly. We really appreciated the care and time he took with us. Highly recommend!

We’ve had a series’s of updates needed due to switching wifi companies. Finally guardian sent Collin K. who was amazing, Knowledgeable and able to solve our problem.
We had other techs out who were unable to resolve our issues and needed to escalate for a senior tech.
Collin I was able to troubleshoot our panels and cameras and Wi-Fi! He knew what At&T needed to change and called with me. Experience was amazing.

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.

Allen C. is a great technician and he did an excellent job!

On 10/30/2025 Tech Collin Kiplin arrived at my home to address a alarm problem.
He was very professional and polite, he had the alarm up and running in a matter of minutes.
Could not have asked for better service.
100% satisfied! Great job.

I have had A Guardian alarm system in my house for many many years, customer service is great! And If I ever had an issue, it was solved promptly!!

My alarm had a zone smoke detector problem. The tech was so polite and gave me valuable info about where to obtain the correct battery. He was wonderful and I hope to get the same tech if I need service again

Collin Kiplin, GREAT JOB

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…..😉

Wendy Barnes.

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

Excellent service and reasonable amount if time spent resolving my issue.

Rudy was fantastic, always checking in with me to let me know where he was in the process and what would be happening next. He was polite, professional, and cleaned up after himself each day. Thanks Rudy!

Rudy did great!

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.

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.

service is good, but they just sent me a past due statement - threatening to collect a "debt" when they messed up their own billing system, then send threatening letters to their customers. Classy.

I like the fact that I did not have to wait on hold and I did not have to wait for the phone to ring 7 times. They answered right away. So I like that and they were so nice about my concerns and helped me fix them.
