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.- Kelly C.

I've called Intelligent Plumbing quite a few time over the last 8 years for any plumbing related issues I had around the house abd must say that every single time they have been honest, courteous, and professional. They came in, repaired what needed to be fixed, and made sure the work are was clean before leaving. I've had great interactions with the techs that came to repair the issues and I will continue to use their services for years to come.- Nyght O.
