Customer Reviews
Renee Hanna
Nick and Antonio are incredible. It was 100° and they worked all day in that stifling heat. They were polite, cordial and professional. They let me know when they were coming in and out of the apartment and kept their work area clean not only during the day but at the end of a long hot day as well. Both Nick and Antonio were a pleasure. I would not hesitate to recommend DNI to anyone who needed help with their AC unit.
Mike Sipiora
Thomas Carter was a fantastic technician for us. Answered all of our questions, was very quick in diagnosing the problem, and most important, fixed our AC and got it working that day. Thank you so much. Highly recommend both Thomas and DNI.
Val Yates
I had terrific service from DNI on an electrical issue related to my AC. The scheduler understood the safety aspect and sent the electrician promptly. Derick was on time, friendly, polite, informative, thorough, and fixed the problem in one appointment. He answered my questions with patience. I value hiring a company that is locally owned and with a solid history of service. I will definitely call them next time I need help.
