  • "No one in the industry can beat HCI Systems"

    Just amazed how HCI Systems delivers as promised. From start (sales quote) to finish (installation), real professionals that know the industry.  I was amazed by the quality workmanship provided on my retro-fit project. These guys got my project completed on time and signed off by my local fire department. HCI Systems is my choice of provider for fire alarm systems.
  • "Thank you again for making us all look good!"

    Project Manager
    It was a pleasure working with HCI. They took a difficult situation in my project and came through to meet the schedule, expectations, and most of all making sure AMC was able to occupy their space. Your team was professional all the way and it was great to work with you personally to get through this project. I look forward to more opportunities to work with you guys. Thanks again.
  • "We neglect to say thank you when the job does get done."

    Project Manager
    We are always quick to demand, complain and insist that the job get done but sometimes we neglect to say thank you when the job does get done. It’s a credit to all of your hard work and all of the hard work of your men and women in the field that made the project a success and for that I want to say… THANK YOU!
  • "Excellent work performed by your Technician"

    Building Manager
    Our existing Edwards 8500 system is outdated and finding good service technicians to perform maintenance and repairs has always been a challenge to our building management and engineering. Over the last 6 months our building has had many tenant improvement projects and there were many "troubled" alarms on the board. We contacted our regular service technician and after many hours billed, their conclusion was "the system is old and requires a replacement." We were introduced to your firm by KCS West as part of their Tenant Improvements. An HCI Technician was called to repair some "troubled alarms" in connection with the Tenant Improvements. As part of the the repair he was able to clear up the panel in extremely short order. With his efforts, your firm has won a new customer. Many thanks for the professional and thorough service performed by your technician!
  • "Certainly wonderful to have you as our Fire Life and Safety vendor"

    Plant Services
    I greatly appreciate HCI's support and cooperation with all of our testing needs. It is certainly wonderful to have you as our Fire Life and Safety vendor.
  • "Want to express my complete satisfaction with your team's performance"

    Hospital Engineering Manager
    I just want to express my complete satisfaction with your team's performance. I believe Doug is the cornerstone to making so many things right for us here at our Hospital. Everybody from the fire alarm division, the fire sprinkler division (can't say enough about Jeff and Don), and the security division. I'm not surprised by the way they perform one bit, it is my expectation that they continue to perform in this manner. Just thought you should know and you can let them know to keep up the good work. It is appreciated and recognized. Thanks
  • "You never let me down when it comes to systems like we have!"

  • "Out of 31 submittals, yours is the only one complete"

    Project Engineer
    I just finished reviewing your product data for the Fire Alarm System. I have to say that out of 31 submittals, yours is the only one that I do not need to get or do anything to. I am extremely happy that the whole submittal was put together per specification and you even abided by the submittal procedure specification. I wanted to take the time to formally thank – you for your hard work on that submittal and I look forward to working with you on this project. If you ever have any questions or concerns, please feel free to contact me anytime. Again thank – you for getting us the submittal in a very timely matter and “complete” per specifications.
  • "HCI Systems is the only company we will use"

    Construction Company President
    HCI has provided Fire Alarm System design, installation, testing and certification work for our company on numerous projects. I could not recommend a company more highly. They are the only company we will use. Between Dan Downs, the engineering staff and his installation crew I can only say they are the best.
  • "Very responsive to our needs"

    HCI was our fire alarm subcontractor and it was my first experience working with this new company, so I thought I would share my thoughts with you now that the job is complete. Although this was a fairly small project, they performed incredibly well. Their submittals were prompt, their shop drawings were well designed. Their salesman/project manager, Dan Downs, was very responsive to our needs. He was always available by phone. Best of all, their foreman was tremendously helpful, cooperative, flexible. He and his crew went out of their way to get things done at the eleventh hour at the whim of the AHJ. As a matter of fact, they stuck around three hours past the appointed time waiting for the inspector to show up for the final inspection, late on a Friday evening. It was a great experience working with a fire alarm subcontractor that actually serviced us.
