I had an excellent experience with Nothing But Water Heaters. From start to finish, David handled everything personally. He was the first person I spoke with on the phone, provided a fair, straightforward, and competitive estimate, and then came out himself to install my new water heater. Throughout the entire process, communication was excellent. David arrived exactly when promised, answered all of my questions without ever, and was professional, knowledgeable, and courteous. The installation was clean, neat, and professionally done. It was obvious that he takes pride in his work. Before leaving, he made sure everything was operating properly, explained the new water heater, and cleaned up the work area. I appreciated the fact that there was no sales pressure or surprises--just honest service and quality workmanship. Replacing a water heater isn't something anyone looks forward to, but David made the experience as easy and stress-free as possible. I wouldn't hesitate to recommend Nothing But Water Heaters to anyone needing a water heater replacement. read more

David came out himself and gave me an estimate that went well below the competition. Our tankless water heater was installed by the end of the week and has been working flawlessly ever since. Thanks for the fair shake David! read more

Outstanding price matched by outstanding service. Replaced my 50 gallon water heater impeccably. Even called a day ahead of my appointment to alert me to a cancellation that allowed them to come early. Great experience. Can't recommend more highly read more

Short version: Hire them for your need, they were terrific Longer version: David was really quick to respond and get me started when my water heater had its last messy gasp and needed to be replaced. He was fast, friendly, efficient and made a not particularly pleasant situation less painful. Thank you David and team. read more

Great company they were quick to respond and had same day service. Best price I found. Highly recommend them for your water heater needs

Don't pay plumbing companies prices! Got a good price from David and they were able to squeeze me in quickly. Great service and about 1/2 some plumbers prices. read more

I found a guy (Dave) who knows enough about my tankless water heater to recommend replacing parts instead of replacing the unit! He ordered them for my tankless, sight unseen because he is an experienced pro who doesn't feel right overcharging people for stuff they don't need! When the parts arrived Dave called and he came by to install them. Total bill $299 parts and labor!!! By The Way...their name is not true! They do other plumbing also, including installing a new salt water conditioner today. Parts and labor were $1900.00 and he flushed my tankless for $149! Great response time, great service, great prices, on time, no mess left behind, and can hold a conversation while working, without stopping, or screwing something up CALL DAVE YOU WILL NOT REGRET IT!!! BTW I got two other estimates for a new salt conditioner and both companies were over $7400.00 read more

I have used Nothing But Water Heaters in the past, and they did an outstanding job! I contacted David to handle yet another water project, and he again came through for us. We have been very impressed with the knowledge, workmanship, and pricing of this company. David is a great guy, and very conscientious about doing the job right. I highly recommend Nothing But Water Heaters! read more

After waking up one morning to a leaking water heater in the laundry room, David was out super quickly to give a reasonable quote! I had been wanting to move the unit outside so I wouldn't have to worry about future leaks in the house and David was also able to get that done. It was a really rare windy day in Phoenix and felt soooo bad he had to build the metal water heater cabinet while battling mother nature! I am just really happy to get that space back in the laundry room and would not hesitate to hire again for future needs. read more

Had a tankless water heater installed by Ronald a week ago. The process from the initial phone call to the finished product was very straight forward. Would recommend for future use read more

Dec. 1 2025, David installed a new tankless water heater for us after our old one stopped working. He was on time and installed it in less than 2 hours. David gave us a fair price and we could not be happier with the unit. Highly recommend Nothing but Water Heaters. David is a great person to deal with. read more

My experience with NBWH was awesome throughout the entire process. I contacted them after our Rinnai tankless started leaking (again) and David came out the next morning, explained my options and recommended a new Navien. TBH I was through with Rinnai and knew I wanted a Navien if it needed to be replaced, which it did. David gave me a very reasonable estimate on the spot and said he could get started immediately. That blew away my expectations. He purchased and installed the tank within a few hours and was very friendly and professional. He took the time to answer all my questions and showed me how to use the unit. We also programmed the circulation feature together. My wife and daughter are happy they can shower again and I look like a hero. If you are looking for a quality tankless water heater this is your company! read more

I noticed that my electric water heater was leaking at 7AM and frantically reached out to a few different vendors. David from Nothing But Water Heaters responded immediately, was able to be at my house within the hour, and had installed a new water heater for me by 11AM. He was friendly and open to answering all of my questions about water heaters and maintenance best practices, and he was very clear and transparent about the costs to repair. When I woke up, I was terrified by how much work, money, and stress this issue was going to take to resolve, and by lunchtime everything was good as new. You really can't ask for a better appliance service call than that - highly recommend this company for any water heater needs. read more

I found "Nothing But Water Heaters" on Yelp, when I did a yelp project where multiple contractors can bid on a job. My senior father had a leaking hot water heater that needed replacement, in the home he rents from me. The contractor reached out quickly for a quote... I did everything through Yelp without a phone call, which was appreciated. It's nice to have things in writing, and not feel like you're pressured to have someone come out and give you an estimate, when you could just as well, send them photos and get a few estimates beforehand, from a few reputable companies. A price was agreed-upon that was acceptable for the job, and they were available to do the job same day. They were extremely responsive, and showed up in less than an hour with a new hot water heater to replace the leaking one. The quality of the install is great, professional, and clean. I paid over the phone, and received photos from the technician who installed the new hot water heater in my rental home. The tenant (my father) was thrilled with the quick response time and the quality of the install. An invoice and receipt was sent less than five minutes after the install was completed. To summarize: responsive, speedy, reasonable price, quality install, good communication, flexible, transparent. I wouldn't hesitate to hire them again! read more

I needed to have my water heater replaced that was still under warranty, and David was very knowledgeable and efficient- I was able to get a full refund for the old water heater, and was offered a better deal for installation than I was quoted for as "unitemizable charges" from my home warranty! This company was very straight forward and quick to respond with offering an estimate, and installation including getting new water heater was less than a few hours, and everything works great! Thank you for expanding your company to Phoenix! read more

Total pros! Better price than Home Depot (by about $100) and service within hours of my call! I really appreciated that I was able to text photos of my current water heater and get a quick quote for a replacement. The technician (Ronald) arrived right on time and was friendly and helpful. New water heater installed for $1550, 1 year labor warranty and 6 years on the water heater. I'm thrilled with this company and will recommend them to everyone! read more
