What Our Customers Are Saying
Susan C., Lewisville, TX
“American Security Devices was an easy choice for our home security system. I have been a customer for over 15 years. They provide exceptional service and response time is great. The representatives in the office and in the field have always been courteous and helpful. I have recommended American Security Devices to all of my family and friends.”

“Dear American Security Devices Team,
I would like to express my appreciation for your team. I have been a customer for 11 years and received wonderful service from all employees. In fact, I have been so happy; I have referred ASD to friends, family, and the office that I work with. Whether it was a call for help with my system or for a new install to our new house, you have always been very quick to respond. In today’s society, it is hard to find companies that are quick to respond, and I want you to know we appreciate it. I also have to say that with two children, it adds a sense of safety knowing we are protected by ASD. When we moved in July, I really appreciated Mark going over the system with my children. It just makes us all feel safe and secure.
Thank you for being a company we can count on!”
Jennifer L., Plano, TX
“When my family and I set out to find a security company for our home, we were extremely nervous. This is a huge step for us. We had never had a security alarm before. We had to feel 100% comfortable with the overall company and with the representatives that we were working with. When we called American Security Devices and set up an appointment to get an estimate, the representative made us feel so comfortable and even recommended us to think about options other than the ones we were calling on. When the technician showed up at our home, he was very professional and polite. Thanks, American Security Devices!”
