What Customers are Saying about David

“We have been working with Alarm Engineering since we built our house in 2015 and to say the least we are very pleased with all of their services. We are so thankful for their protection of our home and our family. Mr. David Mueller, you are a consummate professional and a true gentleman!!” -Mark in Lewes, DE

“My wife and I had our system installed about 2 years ago in early 2016. David Mueller was our sales consultant and he helped us get the exact system we needed. His customer service was amazing, just like everyone else we have dealt with at Alarm Engineering. He made sure that we did not get more than we need or not enough. I would and do recommend Alarm Engineering to everyone.” -Matthew in Georgetown, DE

“I have used David Mueller for my alarm systems on two different homes and wouldn’t use anyone else. Dave was incredibly helpful explaining the systems to me and helping me fit it to my needs and budget. He has also been there for me on more than one occasion to help me better understand and use my equipment. Thank you Alarm Engineering & David Mueller.”  – Don in Delmar, DE

BVE Community and I would like to express our thanks and appreciation to Alarm Engineering and their outstanding staff for the installation of our system. I especially would like to thank David Mueller for helping define and spec our community requirements. David was extremely helpful in ensuring our competitive quotes were in line with our needs. David’s guidance and integrity led our Board of Directors to choose Alarm Engineering as the overall best value supplier. The system has performed flawlessly and our community is very pleased with Alarm Engineering.” -James with Bayview Estates Homeowner’s Assoc. in Selbyville, DE.

“Dear David, my wife and I appreciate your professionalism ever since the first time that we met you. I told you what type of alarm system that we wanted and you provided us with the best equipment and the best price. You did not pressure us in any way and took time explaining the different options for the alarm system.  We have had our system since 2011 and since that time we only had one sensor go bad. Once I contacted Alarm Engineering, the service tech came right out and corrected the issue. I have recommended your service to many of our friends. In 2015, I decided to alarm my place of business as well and again, great price and customer service. Thanks for being there when we needed you.”  – Sam in Millsboro/Long Neck, DE

David Mueller and Alarm Engineering did an amazing job with a security system for our home. The call to Alarm Engineering was the result of a break in at a neighbor’s home. The thought had hit me, what if that was us. I was home alone and my kids and husband were away. Feeling unsafe and talking to a friend they recommended I call David. David was quick to come out to the home, assess the property, and most importantly he sat down and listened. After the home assessment Alarm Engineering did not just sit me down to sell me a product. David asked me questions about my situation and took detailed notes on the answers. They listened to my concerns and adjusted the system for me. After a quick, informative, and actually fun assessment of my home I was on the schedule and the company was out installing our system within the week. David and Alarm Engineering did an amazing job and I have NEVER felt safer in my own home.”  – Karen in Wilmington, DE

“I have been a customer with alarm.com now for a few years. I’m very pleased with their excellent products, customer service, and reasonable pricing. I recommend alarm.com for business and residential service.”  – Steve in Selbyville, DE

David was friendly, informative and we did not feel pressured or feel like we were trying to be sold a system, but rather he was advising us.” – Matthew in Georgetown, DE
