“We were impressed with how quickly ACI responded to our challenge during the busy July 4th weekend and how hard they worked to restore the air conditioning to the building. Thanks to their expertise and the installation of temporary cooling towers, we were able to continue with our scheduled performances and ensure the comfort and safety of our patrons. This experience is a true testament to the importance of having skilled professionals like ACI, who are committed to providing top-notch service to their customers.”
