Testimonials

Called Eric (the owner) to arm a replacement window at my residence. He was prompt and extremely courteous. Eric was able to work around obstacles and complete the job in a highly efficient manner. His prices and overall product knowledge are outstanding. For all my future needs related to home security, I will be sure to call Eric at Dempsey Alarms. Thank you Eric!!

Great service. Eric was very professional and did not try to sell me more services. He seem genuinely interested in providing the best service. They took over my old alarm at a lower rate. Very good & honest company .

Dempsey alarms was originally recommended to us by our insurance company when we had damage to our home. They showed up on time, they did an excellent job, and their charges were very reasonable. Subsequently, I had a question about the system and called. They responded immediately answered all my questions and help me without charge. I would recommend this company to anyone. Their professional and honest that's hard to find these days.

I found Dempsey Alarms on Yelp and I'm so glad I did! I had my alarm installed on my new house and I loved it so much I wanted it in my business also. Less than a week later someone broke into my store and the alarm company called me less than a minute later and sent cops asap!! If it weren't for the alarm my business doors would have been open all night for others to come in as they please. Dustin was our install tech and he is very knowledgeable. He came back to my store two extra times to make sure everything was working properly. Thank you so much Dempsey Alarms!!

I am totally amazed after having Mr. Dempsey install my new home system alarm and thermostat. His service was very quick and efficient, yet I did not feel as though I was being rushed through the steps. The process lasted less than half a day and by the time he left, I felt I knew all I needed to know about the system. All of my questions were answered with patience and no attitude was given when I asked for clarifications or reiterations. This man is very humble and knowledgeable, I am very thankful to have him as part of my contacts.

Additionally, the system itself looks very modern, has a nice interface, is fast, as well as easy to use. Furthermore, the system itself is very extensive with smoke sensors, remote sensors, sensors for the glass in the case that it should break, etc. I can sleep easier knowing that my family will be alerted and better protected from various dangers thanks to Dempsey Alarms.

Dempsey Alarms really provide top quality work at a reasonable price, I am beyond satisfied with their work-I will not hesitate recommending them to family and friends in the future.

Eric was very helpful in transferring the alarm from the home we sold to our new dwelling. He was timely on a Saturday (the only day to new owner of the old house could be available), and came straight to the new house and CHEERFULLY installed the unit in the new house. He was in and out in about an hour. We talked about BYU-Hawaii, Laie, and O'ahu in general. Good conversation while doing a great installation. We only had one problem at our old home, a false alarm during a terrible rain storm in No. San Diego County in early 2017. We were notified in Hawaii and transferred to the San Diego Sheriff's Department, who handled the situation flawlessly. Our hats are off to Dempsey, AND the San Diego County Sheriff's Office.

Eric the owner of Dempsey alarms quoted me 1 to 2 hours at $75 an hour to fix replace the panel in my ademco alarm alarm. The technician Dustin came out had it done in one hour. This is a first for any contractor I've ever hired. Best contractor that I've ever worked with and you will note by my other reviews I'm a tough sell

Delighted to use Dempsey's services. Our Alarm battery was low and needed to be changed. Eric came promptly and changed our batteries. Very nice man.

These guys are great. We have a seldom used brand alarm system on a boat that needed service. Looked up companies in SD and called Eric based on reviews. Even when there was no opportunity for ongoing monitoring or service business, he went out of his way to help us out and get our problem solved. Any owner and company that responds like that is super professional in my eyes. Highly recommend Dempsey Alarms!
