When I first called for the appointment their employee Archie was really nice and helpful and got us a scheduled appointment with Nathan set for less than 48 hours later. Nathan came out listened to our concerns and what we were looking for and had us a quote the very next day.
We kept changing our minds from just cameras to cameras and security system so poor Nathan probably had to complete six different versions of the quote until we had everything we wanted including cameras, alarm system for break-ins, fire, carbon monoxide, and sump pump alarm. Even once we said we were set and they sent us the contract we still made 1 more change which Celina made at 4:15 on a Wednesday and resent to us. We immediately signed, paid the deposit and were then scheduled for Friday install, which I thought was a very impressive turnaround.
Our installers Anthony and Rudy arrived as scheduled and they were just as amazing and impressive as everyone else in the company had been. In fact when they started working on the camera install they realized the house we had bought was actually hard wired for cameras and there was a better option available for us. I know many contracting companies who would have just stuck to the work order they had rather than starting over with a far superior product, but they truly seemed to want to make sure we got the best option available rather than just working to get it done and get home. These two and really all the people I have talked to at Guardian seem to really put the customer first which is so refreshing in todays world. Anthony and Rudy also took time after the installation to walk us through the control panel and the app and showed us how to do everything with the system which if very user friendly and easy to use. Anthony is even stopping back next week with a larger permanent recording storage device that by the house being hardwired we are able to use. Just top notch start to finish; definitely a company I can recommend.

Michael took the time to patiently show me how to install and use the new App for my new system. I'm a happy camper!
inspected the area and explained thoroughly where and how the security system would set up to work best for my property. He is a
very polite and respectable person.
I am satisfied so far with the job and look forward to using it. Tim assured me that zI can reach out to him anytime I have a qyestion. I am very appreciative of that personal connection felt with him. Guardian you are well represented by an outstanding employee. Thanks to everyone.
Thank you.
I would also like to add he was very respectful of my property and any concerns I might have with my system.
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.
Thanks, Michael..
I couldn’t ask for better service.
Hopefully Mike gets some recognition for his fine work.
My technician was Justin. A knowledgable nice guy who knows his stuff and made the process go by quick. If I were to require any technicians to come out for any reason in the future, I'd request him and be happy to wait whatever time was needed. A lot of people may know how to do the job but not everyone is great at customer service. He is.
We certainly appreciate the customer service he provided. Thank you.
He did a great job
Alarm again in the further.
