Bob, the owner of Mr. Tankless, is a master plumber who specializes in tankless water heaters. He is courteous, knowledgable, articulate -- especially in his explaining how our new tankless water heater operates -- and a pleasure to deal with. He and his two helpers took out our old rusted tankless water heater and installed a new Navien tankless water heater up in our attic in just two hours. I highly recommend him. He and his crew were worth every penny. read more

My second water heater fail in several months. I live in Teravista and with the hard water and builder grade components, getting anything to last more than the standard warranty is dicey. So when the second water heater went, we decided to go tankless. We called the two authorized Rinnai dealers and Bob (Mr. Tankless) was the most responsive. We missed each other a few times but he kept on it. After a phone call discussing my needs, Bob told me the unit, RUR199i, and gave a quote. He visited on a Friday and installed Monday morning. All pricing and forms were completed and no last minute uh oh charges. Some of the benefits: He didn't need to modify the roof as some installers warn. Without an outlet, Bob loaned me an extension cord. Bob made use of most of the existing plumbing and aside from the framing, not much was new for tankless technology. Oh yeah, and he likes dogs and will play with your pup while carrying on his work. read more

If you're looking for someone to replace your hot water heater, look no further!

Mr. Tankless - a tankless water heater - Plumbing Near Me - Cedar Park, Texas

I called Mr Tankless when my tank water heater died. It was in the attic. I had him replace it with a tankless water heater. I called 5 different places. Mr. Tankless was $1100 less than the competition. I am a single mother working two jobs. I went with Mr Tankless and I am so glad I did. He came two days later and installed it in under 3 hours. I have hot water again! I don't have to worry about a 50 gallon tank leaking through my ceiling now. He was professional, courteous and fast. Not to mention the best deal in town!!! I did my research. read more

The glowing reviews are spot on! From the initial phone call to follow up was outstanding. Our 17 year old tankless had finally played out. Bob and his team installed the new tankless and made sure that not only were my hot water issues resolved but also my water pressure problems. My shower this morning was so fabulous!! The water heated up in less than 30 seconds and the water pressure was glorious! Don't hesitate in calling them. Highly read more

Our house had a Mr. Tankless installed water heater when we moved here over ten years ago. Each fall I would have Bob or Brandon come by to descale and inspect our unit. During the "Big Freeze" of February 2021, when travel was impossible, Bob communicated with me to instruct me how to protect the unit and water lines from freezing. This fall (2023), our old unit was ready to be replaced and I now have a brand new Mr. Tankless unit that included recirculating hot water technology. Brandon and his assistant got it installed and it works great. I really appreciate the working relationship that extends back more than a decade. read more

We thought our tankless water heater was giving out since we didn't have hot water, only warm. Bob came out and took a look and said our heater was fine, but that we had a problem with the plumbing and needed a plumber. He gave us a contact and now the problem is fixed. Mr. Tankless didn't charge us for his time!! Very friendly, very easy to work with and obviously, a very honest business. read more

I had this guy replace a failed hot water heater. I got a Rinnai tankless, which is installed outside my house. He assured me that the model he suggested would be eligible for the $650 rebate from Texas Gas Co. The day of installation I immediately had problems. They shut off the gas at the meter, and damaged it somehow, causing it to leak. When the Gas Co. came to fix the leak, they shut off my gas because a required pressure test had not been performed. After a day and an inspection, they turned my gas on - no thanks to Mr. Tankless. One of the conditions for the rebate was that you must have a permit. The permit was opened with the City of Austin, but when their inspector looked at the work, he said more needed to be done, but that Mr. Tankless was responsible for doing it. Ever since then, I can't get ahold of the guy. I requested an invoice for my rebate and got no response - multiple times. There's something crooked going on, and it looks like I'm going to have to take him to court. Do yourself a favor and do NOT hire him, no matter what he says. read more

Bob and his team did a good job installing the tankless water heater. However, after a few years of owning the unit it has been difficult to get someone back out to deal with a few issues. One major issue was with the units timer. This unit is the little black box that magnetically attaches to the side of the unit. Its job is to tell the tankless water heater when to cycle and when to not. The timer unit requires the use of an app on your phone to program. My timer unit seemed to have reset or something, so we would not have any hot water during peak times and when I discussed this with Bob he simply said "you'd have a better chance calling the parent company for support". This was maybe a year after owning the brand new water heater. I said, fine. I guess I'll deal with that myself. After some time passed, I asked him several times to come out and do a flush on the unit since its been about two years. He did not reply back. Fast forward to today, we had a freeze which caused the tankless water heart to "pop a line off" the unit. The pan was full of water (not overflowing) and water started leaking from my ceiling. Once I soaked up all the water from the pan, the water stopped leaking. I called Bob and through a bunch of texts he came out. Due to the fact that he could not give me a precise timeframe (mid-morning he said) I was not able to be home, however my partner was. Bob came in and pushed the line he found that popped off back onto the unit stating "this is how we use to do it", to his co-worker. Then he left. What about the pan?? He said "that's not the issue". I asked him to do a flush / annual maintenance AND address the leak issue!! In my text messages to him I stated I wanted BOTH items addressed and potentially replace the drip pan. Unfortunately, since I could not get a specific time from him, I was not home and he left telling my partner, "its the line that popped off" and left. Long story short, he showed up after what I would consider a painful process (remember this is NOT the first time I reach out to him) he's a nice person, but I just don't think he's setup to handle real world issues like this with supporting people and getting the problems addressed. Sure he "pushed the line back on", but that's only a temporary solution. Once it freezes again, I'll have more water pouring into my living room. No long term solution was supplied from Bob "Mr Tankless" and he's off to another customer. What I wanted was two primary things to happen, a service / flush AND a permanent FIX for caused by the "Old Way" they use to install the condensation lines. Maybe even an estimate to replace the pan if I wanted to sleep well at night knowing it wasn't the Pan?? No.. None of that occurred. I've called another company out to do a full install review and assess the leak and "line popping off" install issue. I am assuming that the install of this "line" was Mr. Tankless fault during the initial install and they do not install the lines in this way anymore, but none of this was said to me or my partner. This was "overheard" while they were in the attic, so keep that in mind. If he finds something wrong, he may or may not tell you about it. This is the last time I'll ever call him. The difficult support and communication issues are problematic and I always feel like I have to walk on glass just to get him to show up. read more

After months of different plumbers coming out and not being able to figure out why our tankless heater was not working, we finally got referred to Bob. Mr Tankless thankfully figured out the issue very fast! Wish we would of called them in the first place! Very friendly- Highly recommended! read more

My water heater was still working, but it was 24 years old so I knew I needed a new one. Bob from Mr Tankless returned my call very shortly after I left my first message - he cam right over and gave me an estimate and completed the job 3 days later. I had a conventional water heater installed and was very pleased with the cost and quickness in completing the work - Nice folks! He even replaced the wall valves and installed flexible hoses for my washing machine for a nominal charge. I highly recommend Mr Tankless!!! read more

Goes above and beyond for his clients. Replies in seconds and will be at your house in minutes. Highly recommended and would recommend to friends in the area. read more

Robert and crew were great! Our 16 year old old water heater needed to be replaced and I wanted more information about going tankless. I had concerns given that so many tankless went out during the epic freeze. They answers all my questions (I had a lot) and addressed concerns. The install took about 3 hours and they were very professional and took covid precautions. We were able to move it outdoors to free up the water heater closet. I did a ton of research on plumbers and all the recommendations were spot on for Mr. Tankless. Highly recommend. read more

Needed to swap an old tankless with a new and these guys got the job done fast. Quick, clear, and professional.

Bob responded to my service request on Saturday real quick. My water heater tank rusted out and water started to leak about Friday night. I reached out to Bob and he responded quickly and after a couple of pictures about the tank, he scheduled his crew to come over Monday morning. The crew came and within an hour they installed the new water heater tank for me. That's what I call a good business model. It is a pleasure to do business with you! read more

Bob came out pretty quick and gave me a fair estimate to replace my old water heater with a tankless. He and his team were able to get the job really quickly and I'm happy with the service he provided. We didn't have an extension cord and he had one ready for us. I would definitely recommend him to all family and friends in the greater Austin area. I also appreciate that his crew all wore masks. read more

I have been working with Mr. Tankless for close to 15 years. Our first water heater was leaking every couple of years and we would call the same installing plumber. Mr. Tankless came out and discovered that the electrical connection to the water heater was improperly done causing it to burn out. We quoted several plumbers for a tankless unit and Mr. Tankless, Bob, was reasonable and his work is excellent. We have been very happy with his service calls and general knowledge about our system. So many plumbers today are complete swap out contractors, not knowing how to fix anything. Tankless systems are great but they are complicated systems to install. Mr. Tankless is a reliable and fair contractor we are so happy to have found in the Austin area. John Dz read more

Shoulda called Bob Lemons at Mr. Tankless first. Two others flaked out on their appointments. Bob answered his phone right away (no "leave a message and we'll get back to you"). He set a time to come by and showed up on time. He could see that we were retired on fixed incomes and cut us the best deal he could. It was more than fair. He and his partner showed up early the next day and got the job done. Need a new water heater? Call Bob. You won't be disappointed. read more

This is our 2nd Tankless! We called Mr. Tankless, AKA Bob to our home 1 1/2 years ago and again yesterday for a Condo we own. Both times Bob was quick to respond to my call, made an appointment to assess the conditions of the installation, and was on time for that appointment. Afterward, he provided an estimate for work within min. I scheduled him to do the work literally the next day. His installers demonstrated complete confidence in their work and installed and hauled off the old tank water heater within 3 hours. Our first experience with Mr. Tankless led to 4 referrals and installs, my 2nd included. This experience will certainly do the same. Thanks, Mr. Tankless! Your positivity and enthusiasm are so professional and refreshing. read more

Mr. Tankless provided top notch service for me. My issue had to due with hot water running out. Strange thing for a tankless water heater, right. Well he knew exactly the problem right away. He and his associate explained to me that it had to due with the need to have a consistent water flow and the need to remove any sediment from the faucet that was restricting the waterflow. He and his associate were in and out in about 30 minutes !!! I highly recommend Mr. Tankless read more

Just moved into our new house and the water heater wasn't working too well so we made plans to get a tankless in September. Well the old gas water heater had other plans, after smelling gas, it got red tagged and turned off by Texas Gas Service. Bob and his crew were out midday Monday to look at things for us to see what our options were. We pretty quickly decided to fastrack our plan to go tankless. Bob was able to get us on schedule Tuesday morning. They showed up at the time indicated and were done in in half the time estimated. Bob and his guys are all really nice and personable. They introduce themselves (unfortunately I suck at remembering names unless they are written down) and get right to the job. It was nice to hear a bunch of guys laughing that early. You can tell they all enjoy what they do and working together. read more

Mr. Tankless is fantastic! We had an issue with our tankless water heater, (no hot water), from the roofers removing and reinstalling the outside vent during a roof replacement. We called Mr. Tankless and Bob came out the next day. He quickly identified the issue, got a new vent, and coordinated with the roofing company to get everything working properly. Bob is courteous, professional, and efficient. Our tankless water heater is pretty old...when it needs replacing we will be calling Mr. Tankless to install a new one! read more

Mr. Tankless refuses to refund all or any part of the $525 we paid for a new Navien control board and install labor. I called MT because the unit displayed a 003 error code several times. I was able to override the error and reset the unit - but, at the third instance, I figured it was time to call for help. So I called MT based on good reviews posted online. Here's what happened next. During my first phone conversation with MT, MT stated that the control board needed to be replaced because this is their experience with the 003 and other error codes. MT dispatched a two-man team with a replacement control board. They installed this replacement board but could not get it to work correctly. Water temperatures fluctuated between cold and scalding when tested. And the unit did not respond to control settings at the front input panel. Also while testing, the mixing valve began knocking intermittently. At this point, the MT techs on site called Bob at MT, and Bob suggested that I needed to replace the entire unit - approximately $1600 for the unit plus $1600 for install labor. Shortly after, I spoke with the Navien rep responsible for this geography. He put me in contact with a second plumber. Working with that second plumber and that Navien rep, I have since learned that Navien procedures call for plumbers to first inspect the unit, on site, opening it up, working through programming and error codes and components while talking with support techs to discover and identify the problem. MT failed to follow this Navien guidance. In addition, the MT techs working on site at my house called Bob for guidance; they did not call Navien, thereby failing to create a record of the repair at Navien. With the Navien techs on the phone, that second plumber determined that MT failed to correctly set at least one dip switch on the new board. With that switch set in the wrong position, the replacement control board could not operate correctly. Also, because they were on the phone, that call by the second plumber created a repair record at Navien. Also, working error code by error code, that second plumber and the Navien techs discovered and determined that the tankless unit would not operate correctly because a wiring harness had burned out and was visibly charred -- something you can only discover by first opening up the unit, working on site, going through the error codes, inspecting components. Knowing what I now know, working with the second plumber, I contend that MT did not follow Navien repair procedures that call for on-site inspection and diagnostics before any repair begins - procedures that also call for plumbers to work with Navien techs over the phone as they inspect and diagnose problems. Knowing what I now know, I contend that the original control board did not need to be replaced - because the wiring harness was the problem; the control board could not send and receive instructions over the bad wiring harness. I have suggested to Bob at MT a compromise settlement - refund the cost of the control board, $325, while he uses the remaining balance of $200 to pay for the install labor of the MT team. Bob refuses. That's my experience with Mr. Tankless. read more

Bob from Mr Tankless is fantastic. Our old piece of crap water tank heater went out again. It was our third water tank to go out in 22 years. The water was running down the side of the old tank water heater like a waterfall! As you can see in the picture... The drip pan is only a half an inch wider than the water tank. It is a miracle that my house was not entirely flooded. I told myself that I am not wasting my time buying another water tank water heater. So I called several different companies to come out.The guy from ARS didn't know much and told me that the job would be very very difficult and that we need to put another hole in the roof. Bob from Mr Tankless said that no extra home is needed and used the existing water heater vent. Radiant wanted to charge me $350 extra for a special valve that turns off if there's a water leak. Bob from Mr Tankless knew everything about the Rinai tankless water heater and told me that the water cut off valve is already built in into the system. Another company (not Mr Tankless) also knew very little about tankless water heaters was telling me it's going to be very expensive and difficult. However Bob knew everything about tankless water heater's. He answered all my questions and he was also was much cheaper than the other bozo companies. I absolutely love my tankless water heater. I would recommend getting the top of the line Rinai tankless which has the ability to turn on remotely with your smart phone and circulate hot water before you need it. It's also great because you can change the temperature of the water from your smartphone. read more

Our tankless water heater started leaking during this freeze. We called Mr. Tankless and they got here surprisingly fast given how busy they must be.

They could have easily sold us a new unit, but their honesty saved us thousands. Would definitely do business with them again. read more

Replaced two water heaters with a single Tankless. Couldn't be more happier! Would recommend!!

Talked to Bob about my situation which required ordering parts. He was able to quickly order them under 12 hours and work on my water heater the very next morning. Bob and his right hand guy did a super fast job and gave us some great advice on how to check our water heater (ours is a bit old) and gave us an idea of what a tankless water heater would look like in the future. The price was very reasonable. I was very impressed that he showed up early about 15 minutes. He also knocked out the work in about less than half an hour. I would totally recommend him to anyone in the area. read more

Mr. Tankless was hands down one of the best service providers I've had out to my house - I couldn't recommend him enough! I was referred to him from another company that didn't service my brand of tankless hot water heater, and Mr. Tankless himself got back to me the same day. He was at my house the next morning and it turns out we had a flow restriction problem with our shower heads which was completely unrelated to the hot water heater. He let me know how to fix the issue with our shower heads and didn't charge me anything for the trip. It's rare to find such honest help these days, so don't hesitate to give Mr. Tankless a call. read more

Wow! Awesome gentleman! I left a message and he actually called back! He answered my questions and gave me some suggestions about how to choose a tankless water heater and the installation.

Austin is lucky to have you! read more

The team of 3 from Mr Tankless came in early and by noon they had removed my two old tank water heaters and replaced with a new tankless water heater.
