Quick response and fantastic work quality. Great value and excellent service. Waking up on Saturday morning to a broken heater is no fun, but they made it so easy read more

Wish we knew about Efficient Water Heaters sooner. We had to replace our tankless water heater on short notice and had a new Navien tankless water heater installed by another company. Unfortunately, it took 2+ mins to get hot water. The installers came back multiple times over many weeks trying to fix it -- no luck. In desperation, we called Joseph at Efficient Water Heaters who came out and quickly diagnosed the installation issue. The next day, Omar performed the work and now (finally!) our Navien operates as intended. This business is Navien certified and it shows; they definitely know what they are doing. Oh, and they're very personable & professional throughout. Just call or text them to solve your water heater needs. No need to mess around with anyone else. read more

Great work. Props to Omar who worked on thanksgiving. They were rated good on yelp and their quote was in the middle of the three i received so I went with them. Upon arrival, he laid down tarps on my floors to protect against damage and dirt. He then did a removal of the old 50 gal tank, cleaned all the debris under and adjacent to the tank. After, he did a super clean install of the new one. All the flex pipes were routed nicely. Additionally if you look at the old tank, the gas line was installed doing a 180 to attach it to the tank. The new tank was done right. I am glad I went with Efficient Water Heaters and will definitely use them again if i am in need. read more

cancelled last minute on us 3 times in a row over a 3 week period, but did a really great job before. I won't be doing business with them again, but if you can get them to come out, they do a great job. read more

My 13-year old Bradford gas tank water heater started rumbling very loudly like an earthquake and had sprung a small leak at the base, dripping into the drip pan but not overflowing luckily (turning down to Low helped alot). Called Joseph and he was able to come out Sun early morning. He and his partner replaced the water heater quickly and professionally. We have hot water again! Thanks to Joseph and his crew! read more

I recently had my 50-gallon Rheem water heater replaced with a new 50-gallon Bradford White water heater, and I couldn't be happier with the service. The team was professional, punctual, and paid great attention to detail. They didn't just replace the water heater--they completed the installation the right way. They installed both the upper and lower seismic safety straps, replaced all the necessary fittings, valves, connectors, and trim panels, and made sure everything was clean, secure, and up to code. They also hauled away my old water heater, cleaned up the work area, and left everything looking neat and organized. Their workmanship was excellent, and they took the time to ensure everything was properly installed and functioning before they left. It's clear they take pride in the quality of their work. To top it all off, their price was about **$200 less than every other quote** I received, making them an outstanding value without compromising on quality. If you're looking for an honest, knowledgeable, and reliable team for a water heater replacement or other plumbing work, I highly recommend them. It's not often you find a contractor who delivers excellent workmanship, fair pricing, and outstanding customer service all at once. I would definitely hire them again for future projects. read more

A month ago I put out a call via Yelp to get my tankless water heater flushed. I got a number of instant replies and chose Efficient Water Heaters since they said they were experts in Navien brand tankess which sold me on using them and their quote was similar to others. I was doing some DIY research and saw that pumping vinegar through the system is how the system is typcially cleaned out. I was really concerned and screened for only natural products to be used. Joseph's reply via Yelp's message is below. I clearly asked and he tersely replied that he only used "natural" product and it was citrus based. Ok, great. I booked an appt. Well, once his tech got to our house and we asked to see this unknown "citrus" product that Joseph was annoyed that we asked twice about, it turns out it was Lime-Out -- A CHEMICAL and CAUSTIC agent! The Navien folks, when asked, even tell techs to NOT USE this product, it will damage the internal parts of your water heater!! We called Joseph to confront him on why he was having his tech use this and he HUNG UP ON US! He was also changing his pricing on us as well and luckily we had printouts of our text messaging with pricing from Yelp. The Lime-Out would have "worked" in that we wouldn't have known for months that the Lime was eating away at our water heater's innards plus we'd have trace amounts in our hot water lines in our home. The owner will say "Everything is false." No true. We short paid him by $81 for the work but we were trying to talk to him and he hung up on us so we couldn't. So unprofessional. I'm sending him a check for the rest, this wasn't about the money. I do want to say that he and his team do know about water heaters. This complaint is about him using the wrong product for flushing, one that would have damaged our water heater over time. read more

Joseph installed the 50 gallon Bradford White water heater today. Very responsive and reasonably price.

Outstanding service with Raul. Punctual and explained the process clearly. I have already recommended them to my neighbors and friends.

Contacted them again and had a horrible second experience. They left the burner on the ground, was not communicative and when I questioned them they told me they were going to void all warranties. I would highly recommend going with someone else read more

Raul was excellent. Job was completed with minimal fuss and we are very happy with his work.

I recently hired Efficient Water Heaters for my elderly mother, and I was honestly blown away by their level of customer service. They were incredibly attentive and made sure she felt comfortable with everything that was happening. They also showed a lot of patience and care, which meant a lot to both of us. They gave us their best price upfront with no awkward haggling and no pressure. Everything was straightforward and fair. They also walked us through what needed to be done and made sure the installation would be completely up to code, which gave me real peace of mind. The whole experience was smooth, professional, and far better than what I expected. I truly cannot recommend them more. read more

My water heater was old and leaking and need to be replaced asap. Joseph gave me the best quote out of the few I called. I relied on the Yelp reviews to give me a good sense of the better ones. Joseph was able to respond quickly to my questions. The appointment was made early the next morning. Joseph and his co-pilot were on time, finished the job in less than 2 hours, including cleaning up. I was also shown how to operate my new water heater. I would highly recommend this company to use for your urgent needs. read more

I had a great experience with Efficient Water Heaters in San Jose. They were professional, responsive, and explained the entire water heater installation/repair process clearly.

Joseph called and helped me diagnose the issue to try resolving remotely . He was happy to not have to visit and charge $0. The issue persisted however, and he had the parts available so next morning he came, fixed the issue and charged half what the other quotes did. Amazing service and super friendly and convenient as well. One of the best experiences for an appliance repair. read more

They were prompt, quick, and efficient at getting the water heater installed and disposed of the original heater

Efficient Water Heaters were the first the call back after I requested assistance via Yelp. They were straight forward in their feedback and to the point. My electric heater is about 5+ years old but the water in Santa Clara has a lot of salt that clogs up both the heating element and the tank. They came in, we agreed on the price, they opened the drain in the tank and went to get a new heater and in no time it was back to working. They were also very helpful in explaining what could help with high salt water situation and about opening the faucet in the bath tub so that we don't clog the "expensive" faucets in the house when the water was turned back on. All in all, I am really happy with the work, very efficient and professional read more

I had a great experience with this business! Our water heater was leaking, and they quickly helped us replace it without any hassle. They were very responsive--got back to me quickly even late at night--and communication was smooth and easy throughout the whole process. Their pricing is very competitive, and they showed up right on time as promised. Joseph also gave some helpful suggestions to prevent future issues, which I appreciated. He is very friendly and professional, making the whole experience even better. Highly recommend if you're looking for reliable and efficient service! read more

Really Unreliable -- Would Not Recommend This company is seriously not punctual. Our first appointment was supposed to be 8-9 AM. Close to 9, I called them, and they suddenly told me they wouldn't come until 10 AM. I had other plans and was forced to move everything to the next day. Second appointment, we agreed on 9-10 AM, and I clearly stressed the importance of being on time. Still, they kept pushing it back: 8:47 AM -- changed to 10:30 AM. 10:16 AM -- changed again to 12 PM. Almost 1 PM -- still nobody; when I called, they told me 2 PM. At this point it's obvious they don't respect customers' time at all. Super frustrating experience. Would not recommend. According to the business owner's reply, continue commenting: This company is extremely dishonest and shows zero respect for customers' time. I even agreed to their ridiculous request to expand the original one-hour appointment window into a three-hour window. And still, they showed up four hours late, and I only found out about the delay because I called them -- that's when they suddenly told me it would be sometime after 2 PM. The technician who eventually arrived told me his boss only informed him about this job 20 minutes before. So the owner claiming "we communicated with you" and "we arrived on time" is simply not true. If a company cannot even manage its schedule properly, how can customers trust them with something as important as a water heater? Absolutely would not recommend. read more

Omar did a great job installing my Bradford White URG250T6N. Very responsive vendor and provides all necessary items for a good install.

My water heater started having serious issues at 8 PM on a Monday and by Tuesday morning, Efficient Water Heaters had a brand new heater installed in my garage with new accessories for a great price. Joseph was very responsive to my initial request and follow up questions, had the water heater and all required parts on hand, showed up on time, and got the job done quickly. He was friendly and professional through the entire process, and straightforward with the work to be done and the pricing. What more can you ask for?

Arrived quickly, found and fixed issue, fair pricing. Would happily work with this company again.

Avoid this company at all costs. This has been one of the most frustrating and disappointing service experiences I've had. Joseph installed a tankless water heater for us in 2023. Once the installation was done and payment collected, communication essentially stopped. Recently, I discovered that the service valve he installed does not even properly isolate the water heater, which makes basic water heater maintenance impossible. I called the company four days ago to report the issue and was told to call back the next day to schedule an appointment. Since then, every single call goes straight to voicemail. I've left voicemails and sent text messages and received absolutely no response. At this point, it feels like they are intentionally avoiding me instead of standing behind their work. They also claim to be representatives of Navien in the Bay Area, which I now seriously question and will be verifying directly with Navien, and I will try to report the dishonesty of this shop to Yelp. If you're considering using this company, learn from my experience and be extremely cautious. Once something goes wrong, you may be completely on your own. read more

Scheduling was a breeze -- they got me in quickly and confirmed the appointment right away. The technician (Omar) arrived exactly on time, which I really appreciated. He was friendly, professional, and clearly knew his stuff. The replacement was done faster than I expected, and he made sure everything was properly tested and working perfectly before he left. No mess, no hassle -- just great work. What really stood out was how honest and straightforward they were. No hidden fees, no upselling, just a solid job done right. My new water heater has been running flawlessly ever since. If you're looking for a reliable, efficient, and trustworthy company to handle your water heater needs, these are your people.

What an excellent organization! Big Joe and Frank were so knowledgeable and helpful. They explained why we needed what we needed and provided it quickly and skillfully.

When our 10 year water heater finally gave out we decided it was time to upgrade to a tankless system. Upon putting the request out on Yelp, the owner contacted me immediately and after a few texts and photos shared, he had his team out to my house the next day to install a brand new tankless water heater system. The team sent to work on our house was professional and communication was seamless. The pricing was competitive and follow up was great. Would highly recommend the Efficient Water Heater team and the move to a tankless system. read more

They helped me to install a new water heater with latest building code. I called a lot of plumbers. But all of them told me they can't apply for permit for me. Or the work with permit included is much much more expensive like 2 times more than regular price like they are not familiar with that. Efficient water heater give me a reasonable price. It is more than no permit price. But it is not ridiculous. The work is done well and they called me for the instruction of getting permitted. A month later, city permit granted. The thing not good is they are not patient enough in the call. But in general, the work they are doing is very professional. So I am still give 5 stars. read more
