Get matched with top tankless water heater installers in Fountain Valley, CA

"I hired USA Water Heaters to replace my broken Tankless Water Heater with a new unit. I contacted them through their website about 10AM describing my problem and they responded with a quote and two options in about 30 minutes. I opted for the upgraded unit and by 12:30 the same day the technician arrived to install a new water heater. The installation took about 2 1/2 hours and the workmanship is excellent. I am a very satisfied customer and would use them again. The one day service was a big plus."

"Jake Q. from The Water Heater Company recently helped us with a tankless water heater inspection and descale, as well as installing a pressure regulator, valve, and some copper pipework. He arrived within the window for our initial appointment on 3/7 and was very professional and thorough. The job ended up taking longer than originally estimated, but it was clear he was taking the time to do everything correctly. A pipework part needed to be ordered, so he had to come back to finish the work. The follow-up visit was moved from 3/11 to 3/12 due to a previous job running long, and he arrived slightly after the scheduled window, but once on site he completed the remaining work efficiently and with the same level of professionalism. Overall, I’m very happy with the quality of the work and Jake’s attention to detail. Despite the project taking a little longer than expected, I’d recommend The Water Heater Company and would gladly use them again."

"It went very well and all the issues were resolved quickly. Adan was very professional and confident service person. We highly recommended Payless water heater and plumbing."

"The entire process from the initial call to actually getting to take a shower was easy and pleasant with Speedy Water Heaters. They were upfront with pricing, quick to schedule, installation was clean and timely, the tech was knowledgeable, efficient and so patient with all my questions. I would definitely recommend Speedy Water Heaters to my friends and family! Great job!"

"I returned home from a trip and found water all over my downstairs bathroom and adjoining shed. It was late afternoon and I called Western Rooter who agreed to come out first thing the next day, I had a pretty sleepless night. Rene showed up the next day and assessed the situation and started clean up. Tony soon joined him and the two worked all day until after dark and helped me with cleanup and putting things right. They explained to me what they were doing and why along the way. I felt they charged a fair price. I am so grateful for their service and highly recommend Western Rooter."

"I would absolutely use Jax Mechanical in the future. Justin and Zac were very professional and thorough. I was very hesitant, due to a previous bad encounter with Service Master. Justin and Zac were patient and not condescending. Michael was quick with the bid/estimate and I am grateful for their service. If you need a water heater installed, be assured that Jax Mechanical is the only call you need to make."

"My hot water heater began leaking on the Sunday of Memorial Day weekend - yikes! After requesting a quote via Angi, I received nearly instant communication from Ruben, who then sent me lots of information about what likely needed to be done and what it would cost. He was available same day, and he was able to replace my water heater neatly and efficiently. I am thoroughly satisfied and impressed. So happy he could help me on the holiday weekend. I'm very appreciative."

"Joe came out and installed the new water heater. Kept me updated on what was being done. Very professional and did a fantastic job. I will definitely hire again."

"Would highly recommend Drain Town Rooter to anyone. May be a funky company name but they did a great job on my Tankless water heater install. Ryan was excellent and even came back after I removed the old tank box/stand, had some drywall repair and painting done, to re-route the pressure relief pipe straight down which had been routed around the old tank box. Cosmetic but much cleaner looking. I’d hire them for other plumbing jobs as well."

"I had a great experience with Legacy Plumbing. Daniel was fantastic to work with — professional, friendly, and efficient. He installed new washer and dryer hookups for me, and I really appreciated that he was able to get me on his schedule the same week. The whole job was done in just a few days, and everything works perfectly. Big thanks to Daniel for all your hard work and for making the process so smooth. I’d highly recommend Legacy Plumbing to anyone looking for quality, reliable service!"
