Mr Tankless

Mr Tankless operates as a plumber based in Georgetown, Texas. The company focuses on tankless water heater systems along with standard gas water heaters for homes in the area. With over 35 years handling these units from brands like Rinnai, Navien, and Noritz, they cover sales, installations, repairs, and ongoing maintenance. Homeowners around Georgetown and nearby Austin spots call them when regular water heaters fail or when switching to more efficient tankless setups. Their crew responds to calls for both planned work and urgent fixes to keep water flowing without long delays.

Roy handled service on three tankless units in one neighborhood and returned the next day to resolve an ongoing problem as promised. In another case the crew replaced two separate 40 gallon water heaters with a single tankless model after sending quotes and setup details by text. They opened a unit that another outfit wanted to scrap entirely and performed a straightforward repair instead. Homeowners note the process stayed quick with clear steps explained on site so nothing dragged on or led to surprise costs later.

Customers keep coming back because the work gets done fast without extra visits and the price stays reasonable compared to bigger quotes from other outfits. They also point out the crew checks the real issue first before pushing replacements and keeps everyone updated throughout. This record of solid results on tankless jobs and regular plumbing fixes adds up over time. DIRT Score 5.0 from 88 reviews on Finds.

“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 his stuff with decades of experience. Nice guy, too. It's important to find reliable, trustworthy, and responsive professionals. (A task that is harder and harder to come by as Austin continues to grow.) I enthusiastically recommend Mr. Tankless for your Austin Texas tankless hot water heater needs. He will be my go-to going forward! Five thankful stars, thanks y'all!”

“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!”

“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”

“After having a different plumbing company perform a whole house inspection of my plumbing systems, and flushing my water heaters (which left the older one leaking onto my garage floor), I received a jaw droppingly astronomical quote to replace the water heaters from that company. Given their inspection left me in an immediate need to replace my water heaters, I was determined to find someone to do the job who would provide a more reasonable estimate and would answer my questions about different manufacturers and models of water heaters. After sending 14 different plumbing companies pictures and details of my old water heaters and describing the tankless models I was considering to replace them, I received responses from 5 and had 3 of them out to my house to provide an onsite estimate. Mr. Tankless was the most thorough in answering my questions and in scheduling a time for the installation. On the agreed upon date, Mr. Lemons and his colleague arrived early in the morning as they had agreed, removed my two older tanks, ran a new drain line to the exterior of my garage, and installed the new tankless water heater before noon. We have water again without the leaks in the garage! UPDATE 26 September 2024: After four service visits, over 11 weeks time, to troubleshoot Error Code 63 (Recirculation Low Flow), Mr. Tankless was unable to get my water heater working properly with help from Rinnai technical support. After reaching out to Rinnai directly, I was able to get a response from Jim Brinkley, Rinnai's Area Service Manager, who made it his mission to get my water heater working properly. Jim contacted Clarke Kent Plumbing and a plumber was sent out to my home. Within 10 minutes of looking over my water heater the issue was solved - a cold water inlet filter full of sediment was causing the low flow error. Once that filter was cleaned out, and an expansion tank was installed (Rinnai covered the cost) Error 63 went away and my water heater is now working properly. Our taps now have hot water in seconds instead of 5+ minutes and my family is happy again! Dropping my original 5 star review to 3 stars to account for the 11 weeks my water heater did not work properly after installation.”

“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 location from the old heater so as to make our attic easier to walk through. Everyone else wanted to charge extra but Brandon did a knockout job installing it exactly where I asked. Do yourself a favor and call Bob @ Mr Tankless and fire those big box plumbers.”
