We've worked with Koorsen for years and they have always done a great job. Anthony Jones, Chad Alfred, Angelique Wilson, and numerous other Koorsen peeps are always a pleasure to work with.

Very Professional, knowledgeable, and friendly. The technician came in and took care of what needed to be done, answered any questions we had, and was a genuinely nice guy!

I live in a building that uses Koorsen. We've had some problems with the system that resulted in it going off for hours at a time, days in a row. They eventually fixed it. hard to tell if management company (KMC) or Koorsen bears brunt of blame. But Koorsen did reach out to me after I left a negative review and was responsive, which I very much appreciate.

The reason why my Assisted Living Community keeps using Koorsen is because of their employees! Their caring attitude, extensive knowledge, professionalism, attention to detail, and efficiency are second to none. I would recommend Koorsen to anyone who is looking for FIre and Security needs. They are such an outstanding company to do business with!

Service tech contacted me about annual maintenance. I had it on my list to do, but appreciated the reminder. We agreed on an appointment date and time. Tech showed up on time, was professional and easy to work with, and took care of all of our needs.

Koorsen has several techs that frequent my company that are knowledgeable and personable; which makes each experience a pleasant one. Our regular tech visits are like visits from friends.

We have been using Koorsen Fire & Security for many years to inspect and repair if needed all of our sprinkler and alarms systems. Their technicians are always quick to respond, knowledgeable and thorough when taking care of any repair we may have. Our representative Amanda Thomas is excellent to work with and takes time to check in on things and make sure our systems are working properly and our needs are met.

I had a service company (not Koorsen) out to service an oven, and the next morning there was no gas service to the entire kitchen. The other service company wouldn't own or even discuss the problem, saying there's no way the two issues were related. I called Koorsen, who talked me through diagnosis and correction of the issue that was caused by another company entirely. And we don't have a Koorsen contract. But after this morning, we sure will get one. :-)

Excellent service from fire panel monitoring, system testing and service. I have had Koorsen Fire & Security since 2009 and have never been disappointed with their service or technicians.

TRAVERSE CITY LOCATION. First called in early April 2018 when I was unable to reach our contracted fire extinguisher company we normally use. Left messages for Koorsen, not returned and then called and spoke with someone in the front office on 04/27/2018. She heard me out on our inability to reach Scott, the salesman and got our office scheduled to meet with him.

This took place on 06/08/2018. Contracts were signed and I was awaiting a call to schedule. By 06/18/2018 I emailed requesting a 10 day update, no response. Contacted them today on 07/09/2018 to request any signed contracts be voided due to their TERRIBLE lack of follow through and extreme unprofessionalism. I would not recommend them to ANYONE.

Very friendly and helpful. He let us know that we can get replacement fire extinguishers from Kidda due to a recall. We did purchase new and are going to be calling Kidda regarding our other ones.
