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.- Ann I.

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

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! -
Our tech took the time to explain the work required for our plumbing. I’ve worked with other companies over the years, and this company goes above and beyond as far as customer service.- Scott S.
