Customer Testimonials
“I have used Ace Alarm’s services since May 2015 in my home. The technicians who came to install the system were courteous, prompt, and quick. Their customer service is top notch and I have never had any issues troubleshooting as they send someone out within 24 hours. I have recommended Ace to all of my family and friends. I suggest you check them out too!”

“For an alarm company, ace alarm was the creme de la creme! They were super friendly and came with a quick install. I especially appreciate the customer service when trouble-shooting. They’ve always come either the same day (once the day after) for me!”
Esther C
“Working with Ace Alarm has been nothing but pleasant. They are extremely quick with responding to service calls (typically next day) as well as dealing with any issues over the phone in a timely matter. Technicians worked quickly and knew exactly what to do once they arrived. I recommend Ace Alarm to anyone who is thinking about securing their home or office. A+”
