The technician was informative, meticulous and thorough in the installation. I’m so relieved that the job was well done, a good product was installed and great customer service.
Excellent company, professional staff, and skilled installers. We called on a Saturday afternoon, and on Sunday morning had our new water heater installed. Luis R. was our installer, and highly recommended. Thanks for the great job!
This company is amazing. A person answers the phone, and gives expert advice. I was able to schedule a same day appointment. The service person, Wesley , called to say he would be earlier than expected . He carefully assessed our situation and gave us options as our water heater was still functioning. We decided to replace the heater and pump as both were 16 years old , well beyond the 10-12 year life expectancy. The installation took 5 instead of 4 hours as a couple of glitches occurred, but Wesley kept us posted. He was courteous and professional throughout the entire process.
I highly recommend Water Heater Only Hayward. I contacted 4 different businesses, and it was the most transparent in terms of what I was getting and pricing.My previous water heater was discontinued in production, so I had to replace it with a new model. Alex B visited my place, answered questions, and gave me a quote. The model, pricing and labor cost etc was officially documented, ensuring no hidden costs and fewer moving parts. In contrast, other businesses only gave me a rough quote and were not clear about what replacement model would be installed. Once I decided to go with Alex's proposal, he visited my place again and described what would be done. He delivered as promised. Alex was punctual and very professional. Note: They also accept credit cards for payment.
I called about 9 am and was quoted a price range and told they could have someone here between 2 and 6 that afternoon. About noon technician Lucas called and said he was on the way. Lucas explained what needed to be done and gave me a final price which was within the quoted range. He was very polite, knowledgeable and efficient, as was everyone I spoke to at this company. Lucas finished the installation in about 2 hours. A very satisfactory experience.
My neighbors recommended Water Heaters Only for me after I told them my heater had started slowly leaking. They dispatched Wesley immediately to inspect my situation, he was super nice and super professional. He also gave a very fair quote and clearly explained the warranty and price costs. A few days later I called again and they immediately dispatched Wesley again to perform the actual waterheater replacement. I really appreciated that since Wesley had already a good idea of the work needed to be done. Wesley has a joy to have around, he worked quickly and explained to me everything he was doing, and explained to me how to operate the waterheater as well as best practices for the future. I've had no issues with the new water heater, it works great and i'm very happy with the quality of the work. Would definitely recommend
Luke did an outstanding job replacing our water heater. He was on time, very professional and did a great job! This appointment happened in less than 24 hours and I'm grateful for the help.
Review only from calling: After calling ~19 different services in the area Water Heaters Only was one of the 2 companies that provided a rough ballpark price over the phone (extremely helpful!) and offered to come out the next day. They are partnered with a water heater brand which seems to make getting one in an emergency easier. Price is acceptable.
WHO, that’s right, Water Heaters Only, that’s who! Called them at 0600hrs to replace a specialty water heater, Mo Tau was at my home 0915hrs and did all of the installation by noon. If you want it done now, and you want it done right, who ya gonna call…Water Heaters Only that’s WHO!!
We found ourselves with a 15+ year old water tank giving us some trouble so it was time to change it. We called Water Heaters Only because of the outstanding reviews we found everywhere and in a matter of a few minutes we had an appointment for the following day (the person who answer the phone (Andy? can't remember) was very professional).The following day Doniel came very punctually, and after a few minutes of conversation we agreed on replacing the tank. He was very knowledgeable, clear on what and why needed to be done, and replaced our tank in less than 2 hours. We had a baby sleeping in the house through the whole process so I guess he was also as quiet as one can be with this type of heavy work.I am very pleased with the job done by Doniel and the overall service of Water Heaters Only. Will definitely recommend !
When I initially called on a weekend Sunday afternoon, your office was so kind and patient to assist me. I needed that while I was hysterical and in complete panic.It is rare I allow an outside contractor into my home.Loni replaced my water heater on Monday, June 20. To date, all is well.Loni is top notch.When I asked, he very distinctly explained options for a water heater for my home in simple terms for me so that I could comprehend benefits and disadvantages of the various options (sizes/tankless).All before replacing my collapsed water heater.I need to add that Loni advertises professionalism and competence for your company each time he rings a client's bell for service.I will be posting my appreciation on social media.I absolutely recommend waterheatersonly.
We have 2 50gallon water heaters on our property.Lucas provided the removal and installation for both on two different dates.The first water heater was urgent since the old water heater pilot assembly failed.The second water heater we chose to call back Water Heaters only due to satisfaction of the first installation (also the old units were 10 years old).Lucas provided professional and excellent service on both occasions.Working with Water Heaters only is simple and professional.Thank youJeff
I had a great experience getting our water heater fully replaced quickly. It stopped working one morning. They were able to come the next morning and it was quickly installed and back working(9:50-12:50). I highly recommend it. Mack Williams was the technician. He was very professional. I really appreciate he explained the benefits of tankless vs traditional water heater. He also explained the steps of the installation process and left the area better than he found it.-Darryl Walker
Water Heaters Only has great customer service. From the first phone call to schedule the appointment to the completion of the installation, everyone I was in contact with was friendly and professional. The technician, Loni, arrived on time and my new water heater was up and running perfectly within two hours.
Our water heater just quit working after 14+ years of service - - right before we were to have a house full of guests. I called on Monday evening at about 5:30 and was able to get an appointment for service on Tuesday 9 to 12. I work from home, so this window worked fine. John A. arrived during that window and was professional and polite. He asked what we wanted done and then gave us a quote. John explained what work was included in the quote and how long the work would take. We found the quote to reasonable. Two hours later we had a new water heater and were very pleased with the work that had been done. The work area was clean and tidy and we are very pleased. We highly recommend Water Heaters Only, Inc.
15+ yo water heater quietly quit. Friends recommended WHO, so I called and received an estimate on new unit and realistic time frame for service. John A. was EXCELLENT. He assessed the situation, explained everything clearly and in great detail. He tried a successful, temporary work-around, but I agreed it was time for a new unit. Installation was accomplished earlier in the day than promised .... and.... for the LOW estimate. When does that ever happen? I highly recommend this business and John A's super service.
My water heater broke on 7/24/18. Benny showed up within the 4 hour window. He assessed the water heater and gave me my options. He replaced my water heater. Left the area clean. Very happy with the end result. Definitely will recommend! Warren
My leaky water heater decided it was time to go on Thanksgiving Day this year and it was quite the inconvenience. I did some research and then called Water Heaters Only on Friday after reading good reviews. They quoted me replacement costs for both a tank and tank less installation and i decided to just replace my tank. I figured it was not an emergency since i still had water. so i said anytime before Tuesday would be fine. They were able to get someone out the next morning. Toa was the technician and he was great. Professional, informative and very pleasant. They didn't try to sell me anything i didn't need. Compared to a big box store i had come out and quote me when it first started leaking, these guys were almost half the price. Great Job and Thank you
Excellent customer service - Competitive price - Quality work! Obviously when you need a new water heater you need it NOW but it is not a regular purchase so who to call & what price to expect can be very stressful. 1st call confirmed that it was probably going to be another bad "contractor" experience of being taken advantage of with the "take it or leave it" attitude. 2nd call to Water Heaters Only and immediately felt like a "customer". Paul provided immediate quote / estimate and arranged for installation to be completed the next morning. Everything was done as advertised at a very fair price. Can a new water heater be a beautiful thing? Yes it can...Great Job!
Steve replaced our 17 year old water heater on May 28, 2015. We were able to get a same day appointment because of a cancellation. Steve called to say when he would arrive, and he was prompt. He answered my questions, worked efficiently, and filled up some buckets with water that had to be drained from the old tank. Water Heaters Only installed our water heater in1998, and it lasted a long time so we knew they had a quality product. When we called them last week, everyone was friendly, easy to work with, and very knowledgeable about the product. I highly recommend this company for offering very good service at a competitive price.
I have been shopping around to find a company that will replace my water heater at a reasonable price, I found Water Heaters Only, Inc. provided the most reasonable price. My water heater installer Loni came at the time promised to provide an estimate. He was very patient and provided the pros and cons of installing tankless vs. tank water heater. When I decided to go with the tank water heater, he provided prices for three different models with different capacities and different energy efficient factors. Loni then left and leaving me to think about it and make my own decision. No pressure at all. I felt very comfortable and 3 days later I called to make the appointment to have my new water heater installed. On the day of installation 3/13/15, Loni took less than 2 hours to finish the job and performed all the modifications exactly as he predicted. No extra charges and he finished the job professionally and everything worked exactly the way I imagined. Great job Water Heaters Only Inc. I would definitely use their services again and would recommend this company to anyone.

“Loni came out to my 94 year old Mom’s to replace her water heater on “Labor Day” holiday. Loni is a true professional, he looked over the job, No hard sell, no BS, just straight and honest. Went over the cost and explained what he was going to be doing. Started the job by himself and was done in about an hour and 45 minutes! The job compared to what he replaced was clean solid and well plumbed. I called numerous plumbers through an app and received phone calls immediately but due to the holiday no one could come out until Tues. Water Heaters Only is large enough that they had the water heater in stock. Don’t waste your time calling a local plumber do yourself a favor and call Water Heaters Only couldn’t ask for more! Eric”

“Leaky old water heater that was leaking into kitchen floor. Called and they sent out Lucas who put me at ease and told me he had a water heater in his van that he could install in a couple of hours tops. Professional, fast and efficient. One of the first times a vendor completely did what they said they could do! Highly recommended!!!”

“The name of the company caught my eyes. It means they must be very good at the only service they are offering. I am glad that I had called WHO. Steve B called to let me know when he was coming and he was very punctual. My apartment is on the 3rd floor, so he had to make several trips carrying / removing tools and water heaters. Yet, he was very pleasant and answering all my questions in between. Looking at my new water heater, I see all the care and the specialist knowledge that Steve B have displayed in the installation. I am vey impressed. Lastly, there was absolutely no mess to clean up. Thank you Steve.”

“Water heater woes only happen in the off-hours. We found our old water heater leaking at 8 PM at night. WHO answered the phone in the evening, were friendly and helpful and scheduled Doniel for the next morning. He arrived on time and looked at our exterior water heater closet. We decided to upgrade the size, and Doniel explained the changes needed to bring the new install into Code compliance, and then he went to work. Most people don’t know that there are many disciplines involved in a “simple” water heater replacement: plumbing, carpentry for seismic tiedown, HVAC for flue exhaust, but also the extras: he cleaned out the closet from years of neglect and left the installation looking wonderful! This was at least 5 star work, could be 6 stars!”

“Water heater gave out after 13 years and we called for help late in the day. Peni & Loni came out the next morning did an excellent job of removal of our old tank water heater and installing a tankless water heater (including upgrading our gasline in our 50+ years house). Took about 1/2 a day to install, including having to drill in a couple places to the outside to install various parts. They answered all of our questions about how a tankless heater works. They were very pleasant and professional to work with. Highly recommend!”

“Technician Beni showed up on time and job was done in under 4 hours. Job included removing old water heater, building a new platform for a larger one, and installing the new one. Beni was easy to work with, explained different options clearly and did a beautiful job. Due to no fault of technician, the cost was about twice the price I expected however.”
