Woke up without hot water today. Called Water Heaters Only and had a new unit installed within five hours. Lucas, the technician, was very knowledgeable and professional. He quoted a fair price and did a quality install of the unit. I would use them again.

New 50-gallon water heater. The tech (Steve) was on time, answered all my questions, and explained what he was going to do. Quality work and a pleasant experience. They also installed the water heater that was replaced, which lasted 23 years.

Great experience from a bad one. Got notified of our water heater flooding our bedroom while we were on vacation. Water Heaters Only was on time and our plumber was extremely professional. I'm very happy with their service.

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!

I had an excellent experience with this company. I called them around 8:15 am and the person answered the phone was very polite and scheduled an appointment for that morning (9-12) of the same date of my call.The serviceman Alex was very courteous and did a great job of replacing my old unit with a new one. He was very professional in his workmanship and finished the installation in one and half hour. I will highly recommend this company to others.

Great quality! Very responsive, our water heater was down. They came out the next day. More importantly, I had been unhappy with the last installation from another company since 2008. Loni and Luis did a much nicer job and fixed the problems the last guys left behind. Thank again Loni and Luis!

Loni provided the peace of mind that we needed with our Water Heater that was causing much stress on our household. He came on time, answered our questions and was able to replace our Water Heater in only a few hours. We could not have been more relieved with this outcome. He was professional and provided a quality installation in exceptionally quick time.Thanks so much for helping us, Loni was the best possible person to install the new Water Heater.

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!

“water heater only” company has serviced Bay Area for many years. They helped us install our first tank more than ten years ago which worked very well. I am glad this company still service Bay Area residents after so many years, Steve and Loni did great job in replacing our water heater tank this afternoon. Very professional work was done! 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!

I had Alex come out and replace old water heater with upmost professionalism! We had old Solar pipes that needed to be taken out and he cleaned it all up so it looks great!. Sean was the person that answered the phone and he was very professional with my questions and set up the repair super fast. Called Monday Morning around 8am and they were out by11am!I would highly recommend them to anyone!!Great job!!

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.

Called at 1:00 pm, sent Chris D. out to replace my 14 year old leaking hot water heater. Estimate matched the office quote. Chris replaced my hot water heater and old valve.He answered all of my questions and was finished before 5:00 p.m.. Excellent job

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!

Loni came out and answered all my questions on which type of water heater I needed. Then came back the next day and installed one. He did a fantastic job and he did really quality work. I recommend them very highly.

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.

Gary Kuhn

The installer (Loni) was actually early and completed the job exactly as he said he would. We were very pleased with his service. He was so kind as to wait to turn off our water while our housecleaners finished their work as they required some water.

Len Lehmann

23:32 22 Dec 21

Super pleased! Alex B. did a great job. The installation was more complete than expected, and the price was very competitive. They know their business and are thoroughly professional. Highly recommended.

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).

Chris came out within an hour of my call. He figured out what needed to be done. Gave us options and let us decide what we wanted to do. He worked fast and efficient. Got us up and running within the 2 hours he quoted us for. Thanks Chris!!!

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....
