Testimonials

What Our Clients say about Us

We value our customers and their opinions. Here is just some of what they have had to say about us.

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.

Arthur Bouvier

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.

Michael McFeron

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.

Jim

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!
