What customers say..
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 an 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.
