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.- Nyght O.

Brian was very friendly and knowledgeable. He explained the problem, our options, and what his recommendations were. He worked very fast, too, and we ended up paying a little less than what was originally estimated. He also made sure everything was put back together and even cleaned up afterwards. We are very happy with his service and appreciate his professionalism. We’ll definitely look to Intelligent Service again for any plumbing issues. Thank you so much! -
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.- Teegan N.
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! -
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!- Arun

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.- Ben H.
