When our 17 year old basement water heater died, we knew immediately who to call for a new one. We called Water Heaters Only in San Jose and requested, Kevin West (the technician who had installed it back in 2008) to install the new one as his work was A+. In fact, the city inspector said he had never seen such good work. So it was a "no-brainer" to request Kevin. He and Chrys arrived in a timely manner and did not disappoint. They immediately got to work draining the old water heater. They then lugged the old 170 lb. water heater up the old, challenging, winding 13-step staircase...and then down the steps with the new one! They really care about the job they do and their work is impeccable. When Kevin first arrived he went over exactly what he was going to do. He and Chrys are professionals and worked well as a team. Their knowledge and service made a very stressful time stress-free! The last thing they did was to slap on the water heater a "Certificate Of Installation" which listed their Service Number, Job Number 214281, Date of Install, Model & Serial Number...all the info we would need if we required additional service. They are so much appreciated! Thanks for such great work!

Our installer Alex Buenrostro was very efficient in removing the old water heater, and installing the new unit. The whole job was completed in less than 2 hours. He did a great job! We have hot water again! We highly recommend Water Heaters Only for anyone needing to replace their old water heater.

This review is for Chrys. He was exceptional. Our standard tank WH went out, and we were considering going to a tankless WH. Water Heaters Only quote was in-line with what others were quoting, but we went with Chrys and Water Heaters Only. From the quote to the work, Chrys went above and beyond to explain the system and how it works. His work was top notch.

The installation went very well and the installer was very professional and did good work. However, there are two issues I had with the service. My original water heater had a 6 year warranty and the warranty runs out in March. So, the original water heater tank was replaced with new one at no charge and parts and labor were charged for the replacement. However, there was a $400 service fee on top of the cost of parts and labor. I contacted Water Heaters Only to find out why there was a service fee with no good explanation. The company did give me a $75 reduction on the fee but I don’t think this type of fee should be charged and certainly not at that rate. In addition, there is no warranty issued on the new water tank. They will only give me the remaining two months left on the warranty on the previous tank they replaced for the new tank. Makes no sense. For these reasons I will not business with this company in the future. Unfortunate, since I have purchased several water heaters with them over the years.

Excellent service. I called on Saturday, and Kevin was at my house the next day. He replaced the thermopile in my water heater. The price for labor and parts was affordable compared to similar local businesses. One place I called asked me to look for the thermopile part and wanted to charge me twice what Water Heaters Only, Inc. charged! Kevin had the part with him on his truck and replaced it in less than thirty minutes. Prompt, reliable, and professional service. I highly recommend Water Heaters, Inc.

I give 5 stars to company and to technician Loni.
Company responded on my late-night call, set an appointment for the next day, informed me upfront about the price range and answered my technical questions.
Loni is a kind, friendly person with sound technical expertise in water heaters. He gave me a call 20 mins before coming, came on time, explained what needs to be done in details and final price. After I agreed, he started working. He is very well organized and focused on the job. After he finished water heater installation, he did a demo on how to run a system and use a new features. If you given a chance to pick a technician – go Loni.

Dear Michelle,
I have been trying to leave a review for Daniel Chavez for to days
Nothing on his business cards worked.
Any way I give Daniel C. Five Stars'
His knowledge on Water Heaters was remarkable. It was very educational I learned quite a Lot. He was on time and in my mind he is a water heater Savant. He is very professional.
I highly recommend him Highly. If you want the job done right,
and a smile on your face, Daniel C. is your man for the job.
I would give him 10 stars but they limited it to 5 stars.
Happy New Year, and to all a good night,
Richard

I trusted the info and recommendations he gave us, and I didn't feel like I was being sold. The previous place I called sent a salesman, and we were quoted $3k more than WHO charged us. Very, very happy! Thank you, Loni!

Water Heaters Only is an amazing company! They quickly responded to my call and sent out Technician Loni to replace my water heater. He arrived inside the scheduled window and completed replacing my water heater within 2.5 hours. He was very courteous and professional. He patiently answered all my questions and did a thorough cleanup when he was done. He also rerouted my existing pressure relief and catch pan drain pipes for improved functionality.

The only reason this didn’t get a 5-star review is because it seemed a little pricy and the main reason I was told it was so expensive was because my water heater is up 1 flight of stairs.
Otherwise, great service, I called on a Thursday evening and they got me an appointment first thing the following morning. Alex, the tech, was lovely and did a very nice job!

We were in need of hot water so I came across Water Heater Only and gave it a try since it has a 4.9 rating. I want to praise their employee, John A., for providing exemplary service. He was considerate, not only did he changed the water heater tank, he cleaned up the clutters around it and added a bigger size pan and wood underneath the tank to prevent issues in the future. I was in awed. Thank you John A.

Water Heaters Only has served us in the past very well and today was no exception. I woke up to a wet garage as my large water heater was leaking. I called the service number on the water heater and I was told that a service technician would be there between 10 and 2. Around 11:20 I got a call from Loni and he was there in 10 min. In 2 hours he took care of the full replacement of our 75 gallon water heater that is a special unit as it also provides water to an Apollo Hydroheat unit.
Loni was very professional and shared a lot of good information. Highly recommended.

It's not a fun thing to unexpectedly have to replace a water heater, but Water Heaters Only made the experience simple and seamless. I called when I noticed our water heater was leaking and they were courteous and friendly on the phone and got me scheduled that day. Kevin West came out to do the replacement, and he was very friendly and professional. He explained the process, provided a quote and got our new water heater installed well. Even without knowing the technical details, it's clearly a better install job than whoever did the last one. Would definitely recommend!

Really great experience with Water Heaters Only and Dan C. last week! We found our water heater leaking at 1pm, and they got a technician out to the house by 3pm. From the initial contact and throughout the replacement process, Water Heaters Only was upfront with details (great documentation and process standards).

So far, everything looks and is working great. I would definitely recommend this business!

Positives: They sent a highly professional technician out the next day to assess the scope of the water heater replacement.
Negatives: The call center experience was underwhelming. The written and signed quote was more than double ($7,250 vs. actual at $3,500) what I ended up paying by using a highly experienced, local plumber. (50 gallon tank, took 2 plumbers ~4 hours to install). Certainly felt to me like price gouging based upon both it being an urgent need and the zip code. Not a good feeling.

Loni came out on a friday to take a look at our ailing water heater, he diagnosed the problem and presented us with options to 1. repair, 2. replace the water heater or 3. have a tankless system installed. Since our water heater was nearing it's end of life, we chose to have a tankless system installed.
Loni and Kevin came today (Tuesday) at 10:30, our agreed upon time, removed the old water heater AND the 3 other older water heaters that we had been told (by other plumbers) could not be removed from our basement. Then they installed our new tankless heater in the place of the old heater, tested it and got it turned on by 5:30pm.
We could not be happier with the high level of customer service, professionalism and easy going competence displayed by Loni and Kevin. Both of these men are professionals and it shows! Water Heaters Only has our business for life!

Great company and great service! I had an emergency water heater fail & leak and Water Heaters Only came out right away. They were responsive on email / on the phone, and the technician Loni was on time and very professional. He installed a new water heater and pump on the same day within a few hours, and I am very happy with the installation all around. Thank you!

Thank you so much!

I called water heaters only at 8:40 AM and there was a technician at my door by 12:30!!😃 Loni came to my house to replace my water heater. He explained about all the choices and was very knowledgeable. We decided on a course of action and he had my old water heater out and the new one installed within 2 hours. He explained about the warranty and exactly how to maintain my new heater. He was courteous and left the area very clean. Loni deserve more than 5 stars!!
Thank you so much Loni!!

I was so happy to find this company after our 13 year old water heater stopped working on Friday evening. They set me up with an appointment for Monday morning but said they'd try to come by Sunday. Fortunately they had time Sunday midday to come by and install a new water heater for us. They were quick (2 hours) and had the water heater we needed on hand. They were friendly and professional plus half the price of the plumber we had talked to before them. Wonderful to have hot water again and will call these guys first the next time I have an issue!

Awesome company, will use again! Our water heater got damaged while a water remediation company fixed a leak in the garage and our water heater was not strapped in properly. Water Heaters Only was able to set up an appointment to give us an estimate and install a new water heater the same day! They were professional and helpful. They did an amazing job and were quick. They made an adjustment to ensure the water heater was secured properly. Thank you for the awesome work!

John A. of their San Jose office did a very professional job explaining what the probable causes were for my leaking water heater. John explained the repair options and quickly and professionally replaced the water heater. He also brought the water heater mounts and plumbing up to code here in San Jose.
Well done John and 'Water Heaters Only' organization.
Sincerely, Richard Hawkins

I had used Water Heaters Only 11 or 12 years ago so I knew they were good but last week, when my water heater sprang a leak, I called them and they responded immediately. Mo Tau, the water heater installation tech, came out the next day. He was extremely personable, highly professional, completely knowledgeable, and made sure everything was done correctly. He double checked everything as he finished and left me with a smile on my face. You will be lucky if you get Mo when it is your time. I highly recommend him and Water Heaters Only.

We needed a new water heater and decided to go tankless. Initial contact was through their website and follow-up by email. Quick replies and answered my initial questions. We scheduled the site visit to assess the appropriate product to install and provide an estimate. Loni performed both the site visit and installation. He was great, phoning me to let us know he was on his way and arrived as scheduled. The installation is clean - see photo. Loni answered all my questions with a smile! He also left his work area spotless.

Water heaters only was recommended by our trusted plumber! I can see why! From the first call and conversation they were prompt and courteous. Steve was lovely. Let me know he was coming, Very friendly, responsive and positive, even though our situation was difficult. There were no surprises and the work was high quality. We would absolutely recommend them and use them again! Thank you, Steve and heaters only!!!

Loni did a great job installing a new water heater for us. He somehow managed to get the new one down our basement stairs and the old one back up all by himself. He was very courteous and answered all my questions and finished the job in a quick and expeditions manner.

Loni, arrived on time, was personable & professional. He performed the installation of our water heater quickly. I would definitely recommend water heaters only. The 1 thing I found some what miss leading is I was asked to leave a 5 star review & if the review was less than 5 star there was a phone # to call instead of leaving a review.

Scheduling was super easy. The technician (Kevin W) was on-time and worked efficiently replacing my old water heater. Afterwards I appreciated the time he spend to explaining the maintenance requirements (there is none), lighting the pilot light, why our old heater was making banging noises, etc.

Nick was so helpful to us. We wanted to do a routine check our water heater and he responded right away, gave us useful advice and was very professional. What I liked most was that he was honest and generous with his time, both which are a rare find now adays. Thank you Water Heaters Only!

John A. installed my water heater and was a class act guy. He was very friendly, easy to talk to, very knowledgeable and very thorough about the process. I only met him for a few minutes but I felt like I've known him for years, that is how cool he was. Any company that has an employee like John gets my approval. 5 stars.

I appreciate the fast and efficient replacement of our 12 year old Bradford water heater. John A (their technician) finished the removal and installation of our water heater in less than 3 hours. He was professional and explained all my questions about the work. It was our fortune to get this last minutes service on a Saturday afternoon. We have guests coming and needed the laundry and showers working before they arrive. Expecting I won’t need water heater service for another 12 years!

We called Water Heaters Only at 8:00 AM and Alex arrived that same morning to install a new 40 gal water heater. He was very professional, extremely knowledgeable in his craft and went above and beyond to answer all our questions. His quick thinking saved us on a another issue that arose that morning (not by his doing). He finished the job in a little over 2 hours and we're very satisfied with his work. We highly recommend Alex and Water Heaters Only and have already referred WHO to one of our neighbors.

Our heater speed producing hot water just before the weekend after almost 10 years of continual service. I placed a service call with my home warranty service (AHS) but their tech couldn't come until Tuesday (Memorial Day weekend). WHO had installed it, so I called them. The same tech who had done the original install, Kevin, came out on a SUNDAY, after calling to confirm the problem and get the model of the heater and controller so he could bring the right parts. He carefully diagnosed it as a faulty thermopile. He replaced that, but the controller wouldn't turn on. He explained that the controllers for my brand often fail after this sort of thing. He replaced the controller and the heater fired right up. He had to charge for the parts, but only charged $50 for the labor as it was a unit they had installed.
I really appreciate Kevin's awesome attitude, and his careful methodology to diagnose and solve the problem at the lowest possible cost, when a lot of companies would have just said "your 10 year old water heater is dead, gotta replace it".
I highly recommend Water Heaters Only as the place to get a quality water heater installed carefully and with great support!

Alex B. did an excellent job removing our old water heater and installing a new 40 gallon water heater. My husband installed our last one and he was impressed by the job Alex did. He was very nice and professional. The total cost for removal and installation was $2,285.00 for a B White brand water heater on 4/12/22. I'm not sure the going rate these days. He did a beautiful job so we are happy with our experience. They even came out the same day so we did not have to take cold showers!! This came with a 6 year tank warranty and 1 year labor.

What an experience! Water Heaters Only responded, evaluated, and installed in la little over 24 hrs from my initial e-mail! Colby in the office was great with the initial contact and decision whether to get a tankless or traditional heater. (We went with traditional) Then our amazing technician, Kevin, came out and did an amazing job removing the old heater and installing the new one. He found errors the previous installers made years ago and made our home safer in the process. The new heater works great. The experience, quality, and customer service really stood out from start to finish. Can't rate them highly enough. Kevin, you rock! Thanks!

Chris showed up on time with a van load of water heaters, and knew exactly what to do. He added a surge tank, leak pan, and third seismic restraint. He added extra shut-off valves to make future repairs easier. Chris is a true craftsman, and explained what he was doing every step of the way. He figured out how to route the drain line from the pan under the door so no holes were needed in the wall. All copper pipe joints were soldered neatly, and wiped clean of flux. The work area was left clean.

I would recommend Water Heaters Only and Chris Devore without reservation. AND the cost was over $1000 less than the next closest bid price!

Well, it's bound to happen - at some point, your water heater will develop a leak. Luckily for us, it was a small one. I called Water Heaters Only, and was able to set up an appointment for the next day. Our technician Steve B. called to let us know that he'd be arriving soon. Steve was very personable, professional, and had our new 50 gallon water heater installed in well under 2 hours. He clearly takes pride in his work! The earthquake straps, supply lines, overflow pipe, and all the other details were VERY professionally done. I highly recommend Water Heaters Only.

I was in a difficult situation of not having hot water due to a water heater that failed. I contacted Water Heaters Only and was able to schedule an installation the next day. Loni, the technician, came and installed my new water heater perfectly. I really appreciate the effort he made to explain all of my options available. Highly recommend for those in the same situation, I found pricing and service to be much better than Lowe's for a water heater made by Bradford White (which they don't offer).

Loni was my craftsman and I got lucky, it's all about the guy that comes to your house! Loni was highly personable, professional and highly experienced. He performed exceptionally well and was very considerate of my property. He even came in under budget, which I found shocking, haven't experienced that in years. Best experience I have had with a contractor in years, very refreshing. Highly recommended....
