Joseph and his team did an amazing job and I'll definitely be using them again in the future. I asked them for a routine flush and descale for our Navien tankless water heater. Joseph identified multiple issues from when the water heater was initially installed and provided me with potential solutions up front. Basically the people I paid to do the same job last year just took my money without being able to do it properly. Joseph and team were super honest and very helpful in explaining everything to me. They also realized my unit was never programmed properly. Now we have hot water in seconds instead of close to a minute. Joseph and team earned my trust and will be gladly using their services again in the future. read more

I searched Yelp for Tankless Water Heaters and Joseph of Efficient Water Heaters called right back. He recommended a Navien brand water heater to me as he considers them the best. He asked a few questions and then gave me a reasonable price over the phone, considerably less than competitors. We made an appointment for the next morning. Joseph arrived on time and handily removed my old unit and installed the Navien tankless unit with recirculating pump. We did some testing and Joseph cleaned up and made sure everything was tidy before he left. I had a very positive, drama free business transaction with Joseph and I would recommend him to others. read more

Efficient Water Heaters - My new Navien Tankless water heater. - Water Heater Installation/Repair Near Me - San Jose, California

When I agreed to hire Joseph C from Efficient Water Heaters through "yelp," I specifically stated that I needed the whole thermocouple assembly installed and he stated he had the kit. We agreed on a time frame of 4:30 - 6 pm. His manners on "yelp" messaging were fine. He showed up at 7 pm instead. It gave me a bad impression when Joseph (who was wearing black overalls on one shoulder and his assistant with sagging jeans and carrying an old brown bag, with tools piled up and sticking out of the bag) showed up at the front door. Joseph said he was the business owner and they were here to fix the water heater. I guided them into the garage thru the back gate. Joseph seemed annoyed as they followed me. "Long day?" I asked in an attempt to relieve the awkwardness of the moment. He just said, "yeah" and followed me. He briefly checked out the water heater and complained that there wasn't enough light in the garage. The light bulb was on. He went to his van and brought his phone to brighten the area bit more. His assistant was also using his phone to make the area brighter. I offered to use my phone flash light to help too, but Joseph gave me an intimidating look while he said: Ma'am, we got it! We will tell you if we need you." He then grabbed a packaged thermocouple assembly kit and blamed his assistant for having brought the wrong one. I strongly believe this was their planned manipulative tactic. He then started removing the screws from my water heater, and I asked him how he was going to replace the thermocouple assembly if he did not have the correct part? I tried to watch as worked, but his assistant was blocking my view. Then I heard him yanked out the copper wire (thermocouple) out of my tank and said: "I will fix it."Then he stared me down as he added: "Your tank is so old that no one has the thermocouple assembly anymore. I am actually doing you a favor by agreeing to fix your heater." He has very poor work ethics. He lacks integrity, professionalism, and he would definitely benefit by considering a bit of empathy for his customers. I sure hope he considers practicing the "golden rule" when dealing with his future customers. He was done replacing the thermocouple in a half and lit up the pilot of the water heater. I am thankful for that. I kept my end of the deal and paid him the agreed upon amount of $250 in cash. That was a very high price to pay for a used thermocouple that he struggled to find at the bottom of his tool bag (the new ones cost about $10.) and for half an hour of his undiligent time. I asked for a receipt, but he refused to give me one before he left my property. He said he would send me one via text. I doubt it, so I followed up via a message on yelp. He did send me one around 10 pm. An effective and professional business owner should not have to be requested to provide a receipt for his services. Dealing with Joseph C. and his indifferent mannerism has been a very unpleasant experience for me. read more

Great service! Reliable. Very responsive and know their stuff. Joseph (owner) has great customer skills

Thought my water heater was leaking sporadically so called Efficient Water Heaters since they installed one for me 8 years ago. They diagnosed the problem as a hot water leak in the slab, but said there was a good chance it was close enough to the wall behind the water heater leading to the kitchen that they could fix it.. Took $1,500 to find out that wasn't the case. Estimated $25k to repipe (way out of line... ended up paying half that) and for some odd reason refused to give me an invoice despite several texts, phone calls and emails. I paid promptly so not sure what the issue is. read more

Had a fun wet & slippery leaking water heater emergency last night! I shut off the water to the tank. There was no leaking on any of the connections up top. It was a 20 yr old water heater that likely corroded through the tank...ahem from lack of proper maintenance by this guy who I always see preening and looking at me in the mirror. Shhhh. Used Yelp to request an emergency consult for the AM. So seemless! EFFICIENT WATER HEATER was the 1st to respond close to midnight. Gave Joseph the sitrep. He expeditiously provided a quote. Loved his quick response! Omar gave me a ring on the phone... Then Presto Chango! Shazam! A new RUUD was installed before I could get home! What a great value! Will definitely recommend EFFICIENT! Thanks again, OMAR! Woohoo! read more

Easy communication and quote was very competitive against others. I went with efficient water heaters as they were flexible with scheduling, price, and reviews. They showed up earlier than scheduled and were ready to go. Install went with no issues and they cleaned up nicely. Joseph gave me some information about the tank install and warranty. No upsells or scare tactics, just the install. Would hire again. read more

Fast good quality work and support. They had us up and running on tankless in less than a day!

Super fast response, quick to show up on a weekend & replaced water heater efficiently.

Joseph and his team did a phenomenal job in replacing water heater at my house. He not only beat the price by a mile, but came by in 2 hours after I called him to take care of my emergency. Look at the pictures to see how clean the job is. I'm going to call this San Jose company for my future plumbing jobs. read more

Never a good time for water heater issues. The response time on these guys is priceless. They were able to quickly tend to the matter. Joseph's no nonsense approach to look into the issue was quickly resolved with no further damage. read more

We were very happy with all aspects of the service. Our water heater was old and stopped working - Omar answered our call right away and was at our house within an hour, gave a good assessment of options, and then installed a new tankless water heater system. He was courteous and professional, and our hot water was working again within hours of calling them. read more

‼‼‼TURN AROUND NOW AND FIND ANOTHER COMPANY‼‼‼ The owner tried to pretend he did work that he didn't do then when called out on it got really aggressive and started harassing us. He then got his office manager to harass us as well along with many threats when we were just trying to figure out what work was actually done. He also told us between 8-9am and then tried to gaslight us into thinking we were the ones who got the time wrong despite having text message history on the issue. When they were harassing us I told the office manager she could talk to me respectfully or not at all and this grown woman decided she couldn't be civilized about it. read more

Joseph from Efficient Water Heaters came to our rescue on Sunday afternoon. We contacted him on Sat evening and he was quick in responding to us. He came by, quickly figured out the problem and fixed it and took the time to explain it to us. And we have hot water! He explained that our tankless heater needed maintenance (which we've never done before). So we made an appointment for him to come by again. He even gave us a cost estimate for the service.

Joseph and team were excellent! Responded right away and could have come out the same day if we had replied sooner, but instead came out first thing in morning the next day. They were professional, got down to work right away and did a five star professional installation... at a very reasonable price. It would take long enough to brush your teeth or shave with electric shaver to get hot water in the shower with the old tankless water heater. Now? About 12 seconds... without recirculating pump! When your old water heater goes, call Joe! read more

5 stars all around for Efficient Water Heaters! When they say they're efficient, they really are. Joseph came by and descaled our Rinnai tankless water heater in no time. He's been doing this for 20 plus years and gave us recommendations on our whole water system. They're also cheaper than most in the area that charge $250 so that was great. Plus their communication is on point. read more

Joseph came out and did exactly what I needed while being courteous, informative, efficient, trusting, and honest, at a competitive price. We needed help moving a water heater temporarily, and Joseph helped move it out while ensuring the cold water line was running properly. He commented to helping us reinstall it when the time comes (still need to request his help, the other project is moving slowly..) No complaints, would recommend read more

Thanks Joseph! Had a broken old water heater before Thanksgiving and communication was really responsive, I had to wait a little for the right water heater but he was able to get it done literally the morning he got it. I think the pricing was fair and good deal as the work looks really good and up to code. Got an upgrade to tankless which should last a lot longer with better warranty and save money in the long run! read more

We had the pleasure of working with Joseph from Efficient Water Heater. He replies to text really fast and gave his really honest and professional advices via text even before we met! You can tell he is a very experienced specialist in this business as he can know exactly what your home needs to get the issues fixed from water valve to water heater both tanked and tankless from our conversations. He is efficient and works really hard with his team as when I called him on a Saturday morning, he was already helping other clients on the field and gave me an appointment on Monday morning at 7 am right away. I really admire how dedicated Joseph is to helping families with their water heater issue. He sent one of his most experienced technician to help me. Omar is amazing. He showed up exactly at 7 am and was able to finish the job within a few hours so I could go back to work. He provides good details and recommendations. Omar is really friendly too! Highly recommend this company! Thank you Joseph and Omar! read more

Update to my post a few weeks ago where I gave them 5 stars. Aftermath: after the service, Joseph asked me to leave him a Yelp review. Sure. Joseph continued that I HAD TO leave a Google review too(I said I won't use Google). He was persistent like the last 10 -15 minutes at my house felt uncomfortable in that never in25+ years of home ownership or anything- have I felt it was being demanded and expected- I have had no issues leaving positive reviews. I promised (weird) I would set up a new yelp and post within 3 days. I texted him that I had completed my review on yelp -5 star super great To my dismay, he responded. . "Great! Now do it in Google";" "no . Again Just who demands and says ok do more . Joseph is good at his job,. I just felt uncomfortable .i never stated I had a problem with the service, but given your response it all makes sense. Yes I paid you cash $240 which included a tip which is the same as payment instead of $250 Joseph- I was speaking of your behavior. I had maintained you did good work; on the fence moving forward- your response was to Deny Deflect and have the audacity to publicly say I have you confused. You claimed discount ? $10 in $250. Because you brought it up! Bashing my plumber? Says you. I know I can trust him. I told you I passed your contact Back to him. This wasn't directed TO YOU. If you want people to post reviews, please refrain from retaliation if their experiences during and after , try to learn and move on. A lot of your reviews are from those with under 3 reviews... looks like you have a pattern. But attacking people on Yelp is the way of showing them who you are. Good night read more

Omar and Joseph came to install a Navien tankless water heater after a 29 year old 50 gallon gas water heater started leaking. They take pride in their work, don't take short cuts, and do the job right. They also had the best quote, as well as fast service - they were the first to respond, and after vetting the other places, went with Efficient. They came out the next morning, and finished the whole installation by noon! I'm very pleased with the performance and features of the Navien - it has hot water re-circulation so the hot water is instant, and it is very efficient: looking forward to lowered gas bills! read more

If you are planning to install a water heater DO NOT choose Efficient Water Heater. They run an extortion racket. Their modus operandi is to install a substandard product and do a shoddy job. When you pull the permit and water heater inspection fails, they will extort more money from you. This is what happened to me almost 6 years ago when I made a mistake of choosing these scammers. I did not realize that at the time. However, recently my water heater had a fault. It was under warranty. I called them thinking they will support their product. They repeated their extortion formula. They did not follow manufacture recommended solution instead they replaced some part. Offered me a 1 year warranty for their labor. I paid up, thinking they have fixed the problem. Should have known better. The problem was not resolved. And when I called them, they initially kept delaying for a month saying they will come at a date and time and then not show up saying they will now come later. Then they started claiming that they will not work with me because I am being rude. I was polite. They had taken the money so they knew they will have to offer to do the work under warranty. So they pretended to be offended. So, heed my advice and stay clear of these scammers. For the reply from Joseph: People notice the dishonesty of the owner. Of course they "were" going to do the work at "no additional charge", because there was no intention to honor the warranty and provide the service. For more than a month they kept delaying when, we, the customer faced inconvenience, and they call themselves "efficient". It was all delay delay then deny service on a pretext, so they can get out of their legal obligations. Absolutely illegal behavior! If you don't believe me, read other 1-star comments to see the pattern - there are so many of them! read more

The service is good and responsive. High quality work and good clean ups afterwards. Highly recommend

My really old water heater of 20+ yrs started leaking on a Sunday afternoon and I called Efficient Water Heaters and Joseph answered the call and after sending a picture of my existing water heater setup gave me a all inclusive quote and was available to come and install a new heater right away. It was so nice to hear that Joseph could come right away and he was at my house with Ray in 30min and they worked liked pros and completed the job in under 2 hrs. Joseph was very transparent with the work he was going to do and did a fantastic job installing a brand new Bradford White 50GAL water heater. I would highly recommend Efficient Water Heaters.

Quick to respond on Yelp and then text messages. Sent pictures of my leaking water heater. They suggested a size and was able to get a plumber out in time.

Good experience with this family run local company read more

Amazing, fast, and professional! Needed to have my tankless water heater replaced back in 2021 and contacted several companies via Yelp. Joseph and team were the most attentive and responsive, with the soonest availability. When you do not have hot water, this is just a bit important. He asked me to send him some pics of my current unit and install location, and it was determined I also needed a minor electrical retrofit. Joseph had an electrician on site within 3 hours and scheduled my install for the next day. In a little over 24 hours from our initial conversation, I had a brand new, fully functional water heater installed, with the old one taken away for disposal. The work area was spotless and the the plumber made sure to test and provide me with tips on keeping the new on from sufffering the same hard-water death as my previous one. Cut to present day.... I messaged Joseph on Sunday 7/23 to inquire about a checkup for the water heater. It seemed like it was taking a little longer to heat up, so I figured it was time for some routine cleaning and maintenance. I figured I'd hear back on Monday or Tuesday, but Joseph contacted me within the hour!!! He had an opening the next day and was able to schedule the maintenance for 4pm. WOW! His team member arrived, cleaned the unit, cleaned our shower head which had also been clogged and all is back to normal with hot showers! They are fast, professional, and Joseph communicates every step of the way. He will tell me when his team is scheduled to arrive, when they are on their way, and to let him or the team know if we have any questions afterward! I would highly recommend this company to anyone in the South Bay area looking for the service they provide. read more
