I've always been greeted with professionalism, kindness and courtesy whenever I've called Valley Alarm. I spoke with Melissa today who went above and beyond in helping me with my concern. Customer service is lacking in so many companies these days but definitely NOT with Valley Alarm!

    San Fernando Business Security Customer

We have been a customer of Valley Alarm for over 20 years. I have never had a issue with my system and great customer service 24/7. I needed an upgrade, so I made an easy appt and Rick Z. was my technician. He was on time (10 min early) had on clean mask & gloves. Super friendly and gave me some pointers. You will not be disappointed with this company!
