“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 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!

“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.
