David from Nothing But Water Heaters called and asked for some photos. I sent the photos and David provided a quote via text message. On the day of the replacement, David, arrived right at the beginning of the estimated window (how often does that happen?) and completed the water heater replacement in just about an hour. While working on my water heater he was talking with another potential client and I was impressed that he was honest and upfront about his recommendation for replacing a solar/electric water heater system, and the pros/cons of what he was suggesting. I would absolutely recommend Nothing But Water Heaters for any kind of water heater issues.

We've used Tankless Pros AZ twice now and couldn't be happier! Two years ago they installed our…read moretankless water heater, and the workmanship was outstanding. They went above and beyond to make sure everything was installed perfectly and neatly. We recently had them install a whole-house water filtration system, and the difference in our water is incredible. The team is professional, efficient, knowledgeable, and genuinely nice to work with. Victoria, who handles the office, is wonderful and always so helpful. It's refreshing to find a small family-owned business that takes so much pride in their work. We highly recommend Tankless Pros AZ for anyone looking for a tankless water heater, electric water heater, service/repair or water filtration system!

They do not charge for a free estimate unlike a lot of companies. Steven Lopez called to let me know he would arrive within 45 minutes of my earliest scheduled time.

He worked efficiently and timely. When he completed he went over everything he had done. I would highly recommend Steven Lopez and Water Heaters Only, Inc.

I want to give a huge shoutout to Benjamin! We had a leak that had been evaluated by three other…read morecompanies, and none of them were able to properly identify the source. Benjamin went above and beyond to track it down and solve the problem. Throughout the process, he communicated with us exceptionally well, which made a very stressful situation much easier to navigate. On top of finding the leak, he also noticed an issue with our AC in the attic and helped us identify the source of that problem as well. I can't say enough about Benjamin's professionalism, attention to detail, and genuine dedication to helping us. He truly went above and beyond in every way, and we're incredibly grateful for his hard work and expertise. I would highly recommend him to anyone who needs an honest, knowledgeable, and thorough technician.

He was very thorough and explained things to me multiple times as the plumbing world is very foreign to me. I felt he was very honest with what exactly needed to be done in order to fix the pipes that were leaking in the attic. During this time, I also had received other quotes that were astronomically high for the same amount of work that Stephen was going to be doing for me. He sent me the quote promptly the next day and answered additional questions I had before we agreed to the contract. Stephen and his dad got the new pipe installed within just a few hours, they got everything back up and running same day. I really appreciated that they were willing to work in the attic in this summer heat. I will be using Stephen moving forward for any plumbing issues I may run into. Thank you again!

It was a call in the evening not too late around 8 PM and a technician came out and she quickly diagnosed that one of my systems was the outdoor fan and the other one was the compressor. I did not agree with her diagnosis and so I had another company come out and they diagnosed it differently and I told the American home and water what the diagnosis was and had them come out and do a second opinion and they said you're right it is the control board. Please keep in mind that this unit is under warranty and it has been almost a full month and I've had one call made to me about the status of the warranty claim and the replacement part and in the meantime, I went with another company to have this repaired under warranty. Two reasons I'm writing this review; number one the technician that diagnose my systems was completely wrong originally and I was able to get it fixed quickly using another company and while I'm still waiting for this company to be in contact with me about the replacement part under warranty. I hate writing this because they've had great service early on and it's a disappointment that their customer service is now what's making me write this. I had to call three times originally to get an update.
