"Alberto came out and installed a new water heater for me. He did an excellent job. My main concern was finding somebody that I could trust, and Alberto was that person. Kind patient, and knowledgeable. He was able to answer all my question and concerns patiently, and thoroughly. Much appreciated Alberto. Also, He was able to get the job done quickly and professionally. Again, thank you Alberto for a job well done!"

"My tankless water heater went out on a Friday night, and the Water Heater Boys were able to replace it on Saturday the next day! Excellent customer service and professionalism. Will definitely call if in this situation again, and will tell my friends!"

"Tony and his crew were skilled, professional and did a wonderful job. When I listed the job on Angi, Tony responded within 20 minutes. He asked about the job, asked for some pictures and I had a solid quote within an hour. Our installation had some challenges and, instead of making these issues more complicated and jacking up the price like other contractors did, he quickly came up with sensible solutions at a fair price. The job was done in one day and our new tankless water heater is superb! I highly recommend Tony and Tankless Plumbing Solutions."

"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"I know it’s rare to give all excellent but it’s the truth. Dan at Beavers was so responsive and professional. I had an hybrid water heater installed which involved a learning curve; Dan made sure we were educated and understood how it operated. The city inspector gave a 5* Plus rating on the install. He’s a full contractor - I’ll use him for other projects!"
