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.

    “Intelligent Plumbing truly saved the day for us!”
    On one of the coldest days of the year, our furnace was barely working, and we were starting to worry. They responded quickly, diagnosed the issue efficiently, and got everything running smoothly again. We’re so grateful for their help and highly recommend them to anyone in need of HVAC services!

    “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.

    “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!

    “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.

    “Overall a great experience and would definitely recommend.”
    Just had an auto-water shutoff (Flologic) installed by Johnny. He quoted a fair price and we were able to get the work scheduled a few days later. He was professional and courteous. Overall a great experience and would definitely recommend.
