The #1 Rated HVAC Contractor in Tucson, AZ

Today we had the pleasure of meeting Aaron. He came to my folks house where we had our water softner fail and flood the garage. He found the that the problem was the water pressure regulator on the main water feed to the house. My folks had hired a handyman off Angie's list previously. To sum it up the last guy installed the wrong regulator. The water pressure was to high. Aaron was able to quickly diagnose the problem. He returned the next day and fixed it. He was a good man. He sat and talked to my folks who are older and made them feel comfortable. He also fixed a minor issue with the water heater. Real solid dude. Intelligent design will also be back to take care of a few roof tiles and replace some fascia board. 5 stars for Aaron and the organization!!

It seems that I can't do multiple reviews on a single business even though they provide multiple different services (pluming, HVAC, roofing, etc.) so I'm updating my current review.

On Wednesday the 12th of November, 2025, we had a general service check on our plumbing by Anthony Brown a plumber at Intelligent Design (ID). He was on time and gave us some good information on our water heater, it's was time to replace it before we have an issue due to its age. We met with his manager at ID via a MS Teams chat so we could all discuss a simple tank replacement or changing to a tankless water heater. We went over the pros and cons, what options we would need or not need and the cost difference over time. It was a good conversation since we gained information that we didn't have regarding tankless water heaters vs tank water heaters. We went with a tankless version, it cost more up front but over time will save us money and the hassle of replacing tanks every so many years, as a bonus its more efficient on natural gas than the tank. ID was able to schedule Anthony Brown the next day to do the replacement. Anthony was on time, pleasant to work with, explained every thing we was doing, had prepared his truck with all of the items he needed and did exceptional work. He also repiped our natural gas line to feed the new tankless water heater, to upgrade the pipe to 3/4 inch from the 1/2 inch that fed the previous tank water heater. We liked working with Anthony Brown and would recommend him and Intelligent Design for your projects. I've attached two photos of the tankless water heater on my wall and one of the pipe change area.

Previous review of pluming done by Intelligent Design:
Jason Shreves and his crew Ryan and Fabian did an excellent job on our sewer pipe replacement from the house to the street. Jason let us know what time he was going to arrive and when he left each day. He kept us up to date on the progress and even stayed very late on the last night to get it done on time. Jason had done our normal house check prior to the work and showed us the roots in the old clay sewer pipe. He's very easy to talk to, experienced, mature, and knowledgeable so we went with Jason at Intelligent Design to do the work. The clay dirt and the calichi were quite a challenge to dig through, they brought in equipment to dig as well as did a lot of hand digging. They all had a great work ethic and dug carefully to not damage any other pipes in the area, water and my rainwater harvesting pipe. I would recommend Jason Shreves to work on your plumbing project. Due to his work ethic and knowledge you won't be disappointed. See photos.
