Get matched with top water heater installers and replacers in Diablo, CA

"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"Carl of Cali Water Heater Solutions replace my 20yr old water heater the same day I requested the work through the Angi platform. He began and finished in approximately 1.5 to 2 hours. The installation was completed fast and efficient. I would recommend Carl of Cali to anyone needing their service and expertise in plumbing. Thanks again Carl."

"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."

"This installation of a new hot water heater was the most professional plumbing job that I have ever experienced. Each step from demo, fitting replacements, and heater installation were all completed in the best possible manner. The job was “Done Right”. Call Alberto when you need a plumber!"

"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."

"I recently had a new HVAC system installed by Aireserv, and I couldn't be more pleased with the results. From the beginning, the team was professional, courteous, and informative. They arrived on time and were very thorough in explaining the detailed installation plan, the features of the new system, and how to operate it. The installation went smoothly, and the technicians cleaned the area while working. Once the system was installed, they ran tests to ensure everything was working perfectly and took the time to answer all of my questions. The new HVAC system has been a game-changer in terms of performance. It heats and cools my home more efficiently than my previous unit, and I've noticed a significant improvement in comfort and air quality. The system runs quietly and maintains an even temperature throughout my home. I also appreciate the energy savings I'm already seeing. My energy bills have been noticeably lower, which I can directly attribute to the new system's efficiency. Overall, I'm delighted with the service from Aireserv and the performance of the HVAC system. I highly recommend them to anyone in need of HVAC installation or upgrades. They provided excellent service from start to finish! A BIG THANK YOU TO ALTON THOMPSON AND HIS TEAM FROM AIRESERV."

"Everything went ok as far as I could tell, but yesterday a plumber told me the gas line was not large enough and that is why the water heater is not working properly."

"They were on time, efficient, and affordable. I called in the morning and they replaced our water heater by the afternoon! Would recommend very highly!!"

"The plumber showed up on time to replace the hot water heater and completed the job in just a few hours and then also give me some advice on a running toilet that I had. He filed the papers for the inspector and the inspection went fine a few weeks later. The price quoted before the job was the price I paid afterwards. I had gotten lower quotes but there was always a caveat on the price offered. Valley Plumbing was straight forward and honest. I would use them again. <br />"

"They fixed a major water leak and installed a new water heater all in one day. They were prompt and did a neat install. I can recommend them."
