Get matched with top tankless water heater installers in Sunnyvale, CA

"I have what turned out to be a 30 year old water heater replaced by this great company and they did it the same day of the quote. The installer had the water heater I wanted on the truck and did an excellent job of putting in the new unit, cleaning up and even replacing copper flex tubing and installing a new overflow pipe out of copper as well, no additional cost. This company specializes in water heaters and couldn't do any additional work on supply lines and they clearly state that on their website. I didn't need that type of additional work."

"My tankless water heater went out on a Friday night, and the Water Heater Boys were able to replace it on Saturday the next day! Excellent customer service and professionalism. Will definitely call if in this situation again, and will tell my friends!"

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Since my current water heater was 17 years old I decided to replace it before it gave out on me. I emailed Better Water Heaters in the evening with the details and got a phone call from Frans who scheduled Daniel to come and give me a free estimate the next afternoon. In the meantime I got another quote from another installer after texting photos of the current installation. Daniel’s estimate was similar for a standard water heater replacement but although I had not considered a tankless install I asked for a quote on that as well after discussing pros and cons with Daniel. Daniel then waited while I discussed this with my wife and since he could do the install the next day I decided on the tankless install and Daniel arrived the next morning and completed the install in three hours. I am very happy with the quickness and quality of the work as well as the quality of the Rinnai water heater that was installed."

"Steve Tinetti, owner of Maverick Water Heaters, is terrific! During the big storm the first week of January this year, our power went out and our tank water heater blew. Painful. We had been thinking about the tankless option for some time so we called Steve about 5:00pm and explained the situation. We talked it through and he came to our home the following morning at 9:00am to assess the situation. Despite being a more complicated installation than most, he said he could do it right away (I think he actually took personal pride in taking on the challenge). Steve bought the tankless water heater we wanted (higher end) and got to work. By 6:00pm that day we had instant hot water (within 24 hours of our initial call). He came back the next morning for a couple hours to finish up the complete installation and we were good to go. I can't say enough about Steve and his high quality, efficient, and professional service. He is a long time Coastside local, independent business owner/operator, and one man show. He explained everything clearly and in detail. He did a superb job and I know this wasn't easy. The heater is in the garage up high on a loft and on the side opposite where the air vent needed to be routed. Yet he made it work and did so very quickly. And, he's just a good guy. A couple months later, we are thrilled with our tankless water heater. We are very glad we made the switch and feel very fortunate that we found Steve. I highly recommend him without reservation ."

"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!"

"They installed a Moen water shut off and a gas earthquake shut off. They were on time, efficient and professional."

"Gustavo from Escamilla Plumbing responded quickly to my call for help in determining whether to repair the existing toilet. I reviewed our history of the 14 year old Toto and our current problem with the small amount of water left after flushing. He adjusted the fill valve and made adjustments to shower valve and sink faucet. Gustavo listened attentively to my existing problems and was very professional in determining his actions and I plan to use his services again."

"Three tasks performed: - Replace exterior shut-off valve, - Install kitchen faucet (difficult to remove old one) - Replace leaking p-trap under kitchen sink"
