About Intelligent Service

A Legacy of Customer-Centered Home Services

The story of Intelligent Service began in 1979 when founder Bob Kerr established Robert Kerr Enterprises after spending nearly a decade working as a journeyman throughout the Chicago area. With a commitment to delivering reliable, expert service, Bob built a company rooted in technical excellence and unmatched customer care. Today, under the leadership of Bob’s son, Jason Kerr, Intelligent Service continues to uphold the same values that shaped us as a company—providing local home and business owners with intelligent, honest, and dependable plumbing, heating, air conditioning, and indoor air quality solutions.

For over 40 years, we’ve approached every project with a thoughtful mindset and a customer-first approach. When you choose Intelligent Service, you’re not just hiring a contractor—you’re partnering with a team that values integrity, safety, and long-term relationships.

We take a smart approach to your home. To learn more about how our team can help you, call (847) 393-0853 or contact us online.

Superior Service You Can Count On

Our promise is simple—deliver exceptional service every time. From confirming appointments to arriving on time, keeping your property clean, and working efficiently, we are committed to making your experience smooth and hassle-free.

Unlike larger, more impersonal companies, Intelligent Service is rooted in the communities we serve. Giving back is part of our DNA, as both Bob and Jason have always believed in doing what’s right, even when no one is looking. We created the “Do What’s Right” Program to help bring comfort to those in need, free of charge. After all, there is no greater reward than to use our skill and resources to help our neighbors—from our honest and competitive pricing to our skilled craftsmanship, we are committed to doing things right.

“I’m very pleased with this company!”
Once again a very pleasurable technician was here. He not only explained before what was needed to be done but after showing me what he did and why. I’m very pleased with this company! I appreciate knowing ahead of time who was coming and then followed up with a call telling me when he would arrive. Thank you!

“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.
