I'm new to the Mount Prospect area and am very happy to have stumbled upon Intelligent Service for my plumbing, heating, and cooling needs. I am a first-time homeowner and used Intelligent to fix several of the problems that were found on our home inspection. Every single person who has come to my home from Intelligent has been super kind, knowledgeable, and excellent at what they do. As a woman, I also love that they send a picture of the service technician you can expect to come to your home as an added safety feature.

Brian was very friendly and knowledgeable. He explained the problem, our options, and what his recommendations were.
