"The Tankless Guys not only installed a new water softener system, they also put in a new tankless water heater and a new toilet. They provided excellent service. We had a range of options to choose from and Sergio and his team performed all the work in a timely manner. Sergio also answered any questions we had thoroughly. I highly recommend them!"

"Never had such a great experience with any contractor. So grateful to Eugene, Artem, Nick, and Alex not only for the great work they did, but for the care and attention they put in for 3 straight months. My house is built kind of complicatedly and the water heater isn't located in the most accessible place, but they were able to make it work. Not only that, but Eugene found me a new tankless water heater that would also work with my radiant floors - not only saving cost, but space as well. To say they went above and beyond is an understatement. They came back multiple times to make sure work was up to par - never half-assing anything. Really hoping I don't have any reason to need to reach out again soon, but if I do, I know who I'll be calling. Also, special shout out to Jeremy, Karen, and Kathy for their logistical help as well!"

"I had my water heater installed by Octavio, and everything was absolutely perfect! He was professional, on time, and made sure the job was done right. The whole process was smooth and stress-free, and the quality was great. I’m extremely happy with the results and would definitely recommend him to anyone who needs plumbing work done."

"Very well. The housemate using it likes it. It works well and is a great improvement over the old, leaking and very noisy one. Will definitely have more work done in the house, as needed."
