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.

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

We noticed that our shower wasn't heating up as fast as it previously did. I called around and noticed all of the positive reviews for Mr Tankless. Bob was super responsive and was able to take a look at our tankless water heater the next day. They quickly found the issue, had the part (check valve) in the truck and was able to get us fixed up in no time. I have since used Mr Tankless for flushing our tankless unit and anything else that has come up. Recently Bob was able to walk me through a few tankless water heater troubl... read more
