Mr. Tankless Company installed my tankless water heater 4 years ago, and it has been functioning flawlessly ever since. Mr. Bob is an exceptionally professional, knowledgeable, kind, and honest individual. I wholeheartedly recommend his services! Mk

This company is a blessing. They were great and fast with fixing my plumbing issues. I definitely would recommend Robert and his team.

It's always nerve-wracking looking for an honest plumber. I am very glad I saw so many positive reviews for Mr.Tankless. I had been told I needed to replace my entire unit by Radiant without them even opening it. Mr Tankless opened the unit and identified an easy fix. He's got a loyal customer here

I had Mr Tankless replace two 40 gallon water heaters with one tankless water heater. He was very responsive by text and took time to explain the whole process and how it works. He was able to get me in the day after he came out to give me a quote. The installation was quick and painless and everything has worked perfectly since. Pricing was slightly better than a couple other quotes I was given and right in the ballpark of what I was expecting. No complaints!

The team at Mr. Tankless did an outstanding professional job! We had 2 Rinnai tankless water heaters with issues that were having error codes and previous plumbers were unable to resolve issues and get waters heaters working. Robert & Brandon had the knowledge and education to properly repair our tankless water heaters very efficiently and swiftly. An honest and friendly crew! Highly recommend for any tankless water heater needs.

The best tankless water heater service in the Austin area! Roy, aka "Mr. Tankless," went above and beyond to service 3 tankless water heater units in our neighborhood, (two were mine). When we ran into an issue, Roy vowed to solve it. He came back the very next day, as promised with a different approach (and a separate pump that worked in concert with our specific breakers). He's a straight-shooting, fairly priced, honest professional who specializes in tankless water heaters, only. So he knows

With a larger family than we used to have, our traditional water heater wasn’t keeping up. After researching tankless options, I interviewed several companies for quotes and suggestions. Bob at Mr Tankless was far and away the most fairly priced, very responsive, and, most importantly, a genuinely nice guy. They arrived exactly when they said they would, they got right to work, and were very transparent along the way about what they were working on and doing. They even installed the new tankle

We had a problem with our Rinnai tankless water heater that two other plumbers couldn’t fix. Bob from Mr. Tankless was able to diagnose the issue right away and get it working again. He has over 20 years of experience with tankless systems, and it showed in how quickly and confidently he handled the repair. He was professional, clear in his explanations, and didn’t push unnecessary work. If you need help with a tankless water heater, Bob is someone who really knows what he’s doing.
