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 Chicago 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.

What Your Neighbors Are Saying

“Will use Intelligent every time we have a plumbing need.”
Our water heater was starting to leak, after having a consultation of our options with a tech, we ordered the replacement for installation. The technician was informative of his steps and provided the pricing & cleaned up the area and explained anything new.

“Intelligent Service has my business for life.”
Both John and Trevor are wonderful people, and great at what they do. I cannot give them anything less than a 5. I would give them both a ten if I could. Very professional service and very personable people. I know that my plumbing and my HVAC has been done right.

- Pamela S.
“I will be using this company again.”
James was very thorough at checking for issues. It turned out all we needed was silicon caulk that a previous contractor had omitted. So the cost was minimal and there was no up selling.

- Steve S.
“I would fully recommend Intelligent to anyone with an old home that perhaps was not updated correctly in the past- and needs a creative thinker to solve your weird plumbing problems.”
Edgar from Intelligent Service was the best plumber I've ever had. He was kind, courteous, and a great problem solver. As with most repair jobs, once you open that wall, a million unexpected things go wrong. Edgar solved every problem and did so in a way that kept the job from turning into a massive beast of torn out tile or cut-outs behind cabinets, blah blah blah. I would fully recommend Intelligent to anyone with an old home that perhaps was not updated correctly in the past- and needs a creative thinker to solve your weird plumbing problems.

Also- the person who called me to schedule everything and check on times was very well spoken, kind, and competent- something I unfortunately have found lacking in many repair service companies of late. So kudos to the office side of this company as well!

- Teegan N.
“Their staff that they sent us were pretty good and clear.”
They informed us what they could do and what options were an available going forward to avoid further issues. They provided us with a reasonable rate after observing the type of problem and if we were okay with the plumber going ahead and fixing issue. He took his time and was pretty thorough.
