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 tankless heater in a slightly shifted ... read more

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.

Amazing service and best prices by far! More than half less than one of the “big named” companies here in Austin and a third less than one of the big box hardware stores. Mr. Tankless even offers a cash/check discount. Navien NPE-240A2-NG and whole house carbon water filter installed and old unit taken away in just a few hours. Professional and friendly. I would recommend this company to anyone needing water heater/tankless service!

I couldn’t be happier with my experience with Mr. Tankless. From the first call through installation, their professionalism, clear communication, and efficiency were unmatched. They walked me through the process in detail, answered all of my questions, and kept me informed every step of the way. The installation itself was quick, organized, and thorough — they clearly know their craft. What really stood out, in addition to their excellent service, was the affordability of their bid compared to others I received. The pricing ... read more

We had a tankless system in our previous home in Florida and loved it, so when we moved to Cedar Park we knew we eventually wanted to go tankless again. Although our conventional tanks were still working, it really bothered me how much water we had to waste before it was hot enough. So, “eventually” became “now.” I called Mr. Tankless on Tuesday. The owner, Mr. Bob Lemons, came over immediately to see what we needed, and had recommendations for modifications that would ensure the hot water would get quickly to the fixtures f... read more
