    Daniel was professional, efficient, and friendly! My Rheem water heater was leaking and it was still under product warranty. I reached out to Daniel because his company NorCal Water Heaters was listed as a service provider on Rheem's Pro Partner directory. I called him and left a voicemail about my issue. He called me right back and clearly explained step-by-step on how to do a Rheem water heater warranty swap out at Home Depot. I scheduled an appointment with him the following day. When he saw my water heater, he suggested other parts to upgrade. I also asked if he could add a new sediment trap and he was able to do so. He showed me an estimate for the installation labor and parts before he started work. After the new water heater installation, he pointed out everything he did. I appreciate his great communication.

    We hired Daniel to help us install a new Rinnai tankless water heater and the process was pretty smooth. Want to leave this review as an appreciation. Daniel was very approachable, texted him and he was to able to provide a very fair quote based on the pictures I sent him. He showed up on the day as we scheduled, took out the old heater with tank, installed the new tankless water heater, did all the piping, installed the recirculation bypass valve in the master bedroom, cleaned up after himself and even registered the device for us. The plumbing job was done very professionally as far as I can tell and he worked around a couple awkward spots in my garage, please check out the attached pictures. It's been about 2 weeks since the installation, no leakage and we get hot water, I even noticed an improvement on the water flow, I think my old heater was acting as a bottleneck to my entire water line. You might hesitant to hire Daniel since he is pretty much a one man shop, but I can tell that he has the ambition and ability to expand his business and will do the right thing when it comes to hiring and ensuring the quality of his service. I am personally not worried that Daniel will go out of business if that's what you have in mind.

    Daniel of Norcal is a pleasure to work with. He is very skilled in his trade, knows the codes and rebates/credit well, charges reasonably. He is also very responsive on the phone, text and email. Highly recommend. My 19 years old Rheem gas water heater finally gave in and I took the opportunity to upgrade to a more efficient heat pump water heater (HPWH) that's also good for the environment. After I ordered another Rheem HPWH from Home Depot I started to look for installers. (Knowing what I know now, I should have contacted plumbers first.) Daniel from Norcal is one of only four "Pro Plumber" in the bay area listed on Rheem's web site, so he is one of the three plumbers I asked for a quote. While talking with Daniel, I learned that if I get the water heater through him, not only the price will be significantly less (with Golden State $900 rebate) but also the contractor model is more durable. So I decided to refuse delivery on my HD order (which took about two to three weeks to get my money back. ). Daniel is very familiar with all the rebates and credits that's available in my area. The price he quoted was very reasonable and the total project cost after all the rebates and tax credit is less than the cost of the heater itself. He also has an electrician he works with who helps with the electrical part of the work at a reasonable cost. It's not usual to see an electrician using a level all the time and painted the wall with home depot matched paint. The rebate from SVCE covers most of the electrcian's cost. I ended up installed a HPWH from Bradford White, which from my own research and confirmed by Daniel, is of better quality than both Rheem and A O Smith (worst). The installation is divided into two parts, first the electrical work, than the HPWH installation. Daniel also helped with the city permit (at reasonable extra cost) . The only problem during the installation was due to a bad mixing valve, which Daniel came back and replaced in a few days without any interuption in hot water usage. My new water heater passed city inspection without any issue and I have been happily using it exclusively in heat pump mode only. The HPWH generates some noise only when its working, it's not loud, and since it's in the garage, it doesn't bother me at all

    Very happy with the heat pump water heater that Daniel installed. He was always very responsive in his communication and did quality work

    Endless Hot Water

    Fast Response, Professional Service, and Great Customer support. I have a 4-year old Rinnai tankless water heater. It has been running amazingly well until one day it beeped loudly and stopped producing any hot water, which was only appreciated after it's gone (kids complained not being able to shower after sports). I searched online and found a quick solution to reset the unit. However, the issue came back after a few days with the same error code ("Error Code 17", if you are curious). I decided to find a local technician - NorCal Water Heaters was recommended from Rinnai website. Daniel responded quickly and showed up the following day (even though a little late due to traffic). The service was quick and professional - it turned out that a part (Gas valve) needs to be replaced, Daniel ordered it immediately and came back the next day. He also offered a detailed instructions on regular maintenance. It is so good to have reliable instant hot water back, as well as know where to get help whenever it won't.

Got good, fair ballpark quote over the phone from Alex, so knew what to expect. Got appmt scheduled for that afternoon with Brian (tech) to come check out our issue. As expected, he diagnosed the issue and was able to install a new water heater that same visit. Got the whole job or replacing the old water heater done within the afternoon!

Alex sent our technician, Rojo, who helped install a new 40-gallon gas water heater in our indoor utility closet, and he was incredibly diligent, professional, and efficient from start to finish. Installing a tank in an inside closet can be tricky, but Rojo handled the entire job seamlessly in just 2 hours. He replaced everything with high-quality components, including: * New hot and cold water flex lines * A brand new water shut-off valve * A new gas flex line and sediment trap * Fully reworked earthquake straps (to meet California safety codes) * Properly updated T&P line and venting He also took care of the removal and disposal of our heavy 18 yr old tank, leaving the utility closet completely clean. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call Water Heater Masters and ask for Rojo. Highly recommended!

When we decided not to, Loni made sure we understood exactly what we were choosing and that it would be a good choice for us. We eventually had some other work done, and this other plumber came and pointed out all of these "issues" with the water heater. Completely scared us with visions of fire risk and heaters not working in the dead of winter, told us that this wasn't to code (even though the permit was signed off). Loni came out again. Explained everything in great detail, as to how it worked, why the other plumber was wrong. Didn't get mad that we wasted his time, just wanted to make sure that we were happy with our water heater. All in all, a fantastic experience.

However, often the truest test of a quality business is how they perform when things do not go well. In my case, I had to go four days without hot water because the unit I received was defective. The day after the install we found the tank had shut down, no hot water. After a reset and restart done over the phone with the installer assisting, the unit unfortunately failed again a short time later. The next day which was a Saturday, another technician came out to swap out the heat sensor which appeared to be the problem. While changing out the part, the tech noticed that insulation near the assembly had burned, and ash was present. He removed the bad insulation, vacuumed it out and restarted the unit. It made a horrible noise, and he spent a half an hour on the phone with the manufacturer tech support trying to diagnose the problem. The noise eventually went away and he finished the repair. Unfortunately the machine shut down again, after we got one lukewarm shower. I called on Sunday, and explained that I was no longer comfortable with the unit being in our house and I wanted a replacement, of a different maker. Without hesitation they agreed, and Monday morning, after acquiring a new model of a different make from their supplier, we got the replacement installed, at no additional cost. These problems are rare, and not the fault of the installer. However, I could not have asked for a more timely and considerate treatment as a valued customer of this business.
