Real Proof That Smart Service Works

“They've earned a customer for life!”
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.

“Clearly this company has all of their ducks in a row, and can be trusted.”
At 3:00 in the morning my sump pump inverter started kicking on continuously, and I called they had a 24-hour hotline available. I chose to wait until normal business hours to have somebody come out, and they came out within 2 hours of opening. My technician was knowledgeable, gave me great advice, found the problem instantly, and then replaced it within an hour.
