Real Proof That Smart Service Works

    “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.

    “Highly recommended and will definitely contact Intelligent Service again.”
    Anthony C. was the technician who came to service my refrigerator and he was amazing. Very professional, polite and knowledgeable about the service I needed. I had a new refrigerator installed a few days ago and needed assistance with the waterline. Anthony explained exactly what needed to be done an

    “I will continue to use their services for years to come.”
    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.

    “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!

    “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!

    “Very impressed with Intelligent Plumbing.”

    “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.

    “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.
