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

"Steve with Maverick Water Heaters came out to my home several times to try and repair my very old (obsolete) tankless water heater. He was very friendly and professional and did everything possible to try and repair the heater before recommending a replacement. Once it was determined that a new heater was needed, he ordered it and then came to my home immediately to do the installation once the heater was available. He completed the job in a timely manner and we were very happy with his service."

"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."

"The entire project from start to finish was fantastic. Within minutes of requesting a quote I received a text with a time they could be at the house. Rodney called to ask some questions, gave me an estimated price and time. Rodney was great to talk to and was very knowledgeable and helpful. Rolando arrived a little early which was great. He figured out what needed to be done and gave me an estimate which was within the range mentioned and started working. It took an hour to complete. Rolando went over what was done and why. I was extremely impressed with Rolando, he was courteous, informative and did a great job installing the water heater and bringing everything up to code. I wouldn’t hesitate to call Better Water Heaters again."

"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."

"Work was fantastic! The team was efficient and organized. Showed up on time and did three days of work in two days. The work was to trench and redo my water line from street to house. Flawless finish. Best of all - very friendly, you can ask questions, get answers and understand the work better with such an amazing team. I would and will hire again in the future."

"I periodically need service on my tankless water heater. I called this company and they answered the phone on the first wring. They scheduled me for the next day. Ron was very professional and did all of the work efficiently. They charged a very fair price."

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Aire Systems of Campbell and Saratoga truly sets the standard for exceptional service in the HVAC industry. Alton, the owner, went above and beyond to ensure I understood every aspect of the process, from selecting the right system for my small home to navigating available rebate programs. His expertise and dedication to customer satisfaction stood out as he guided me through the rebates step by step, emphasizing how beneficial they are despite the effort required. What really impressed me was Alton’s commitment to follow through—he’s not just selling systems, he’s supporting his customers well beyond installation. Daniel, the team lead installer, was equally remarkable. Always punctual and professional, he demonstrated a level of care that extended beyond the job itself. He kept me informed daily, explaining what was being done, what to expect next, and how long it would take. Knowing I had to leave for work, Daniel kindly spent time with my dogs, making sure they felt at ease while he worked. It’s rare to find a company that combines technical expertise with such personal care. Aire Systems, with Alton and Daniel at the helm, earns my highest recommendation!"

"They are very expensive. Yet does good work. Installed a Water heater for my home."
