Real Proof That Smart Service Works

“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.

“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.

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 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.

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.
