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, 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.

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.

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.

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....

Leaking Water Heater

If your water heater is leaking contact us and we can assist you in shutting off the leaking water heater to help minimize any possible water damage. Then you we can help diagnose the problem with your water heater and schedule a repair or a replacement.

No Hot Water

If you notice you have no hot water, it’s often a sign that the pilot on the water heater has gone out. You can try relighting the pilot, but if it does not re-light or does not stay lit you may need service for the water heater. Watch our video on how to light a water heater pilot.

Noisy Water Heater

A noisy water heater is most commonly due to the build up and hardening of sediment in the tank. When the water heater heats the sediment will make popping or rumbling sounds. You can try to flush the water heater to remove sediment, however once sediment has hardened inside the tank it can be hard to remove.
