Thank you Sam and Hot Water Guys for the outstanding service! I was having issues with my Rinnai tankless water heater was vibrating, I first called Blue Frog who charged me a very expensive diagnostic fee and quoted me an $800 repair, telling me I needed major parts replaced. They also delayed the repair after taking my deposit. I decided to get a second opinion and called Hot Water Guys. Sam came out the same day, was professional, honest, and clearly knew exactly what he was doing. He quickly diagnosed the real issue and fixed it the same day without unnecessary repairs. Sam saved me a lot of money and stress. The service was fast, professional, and trustworthy. If you have any tankless water heater issues, especially Rinnai, I highly recommend Hot Water Guys and ask for Sam!

Data sourced from Google Places API · ReviewRank Score
Rankings are based on public review signals only. No paid placements.
The ReviewRank Score (0–100) weights a Bayesian-adjusted rating (55%), review volume (20%), sentiment of Google's up-to-5-review sample (15%), and rating consistency across that sample (10%). Sentiment and consistency are blended toward volume-based priors when the sample is small relative to total reviews. Google selects the sample by relevance, not recency. Full methodology →
We purchased a Rinnai tankless system 12 years ago and this was the first time that we have needed service. Our Technician, Sam, went right to work and when he didn't have a part, came back late in the day to install the last part needed to put the system back in full operation. His diligence, willingness to explain things to me, and dedication were greatly appreciated. I probably could have called someone more local, but I'm glad I called the Hot Water Guys!
Hot Water Guys employee was professional and well knowledgeable. I would recommend the company again and will be using them to service my house. The employee explained well the process.
Brock, George and Mike were personable, professional and very knowledgeable about the project. Installation took about 2 hrs. They had drop cloths from my front door to my washroom. Wife is going to love the new unit. Very pleased with the Hot Water Guys. 5⭐⭐⭐⭐⭐
We moved to Galveston this year and found the tankless water system in our new home to be unsatisfactory. It's a big house, and the distance between the water heater and the master bath is considerable. So we contracted with the Hot Water Guys for a new system. Hot Water Guys installed a new Rinnai REP199iN system, including a smart recirculation pump. The installation required new duct work, valves, expansion tank and drain - a fairly complicated endeavor, in other words. The installation process was smooth as could be, communication was excellent, and the water heater itself has been outstanding over the three months we've been using it. Fantastic company installing a top-quality product!
