"My 12-year-old water heater was on its way out, and it was finally time to replace it. Iâ ve always wanted to go tankless, so after many hours of research and finding reputable local plumbers in my area, I reached out to the Water Heater Company to analyze my current situation and come up with a replacement solution. Again, my goal was to go tankless; however, after Tanner from The Water Heather company surveyed my property and went over all my options, it was determined the configuration of my main gas line and proper placement of the unit would not be conducive to install a tankless unit as there were many obstacles, hours of labor, and resorting back to a tank heater would be the best option for me. Tanner suggested I go with a company called Bradford White, which has fantastic reviews and a unit that will give me some longevity. I decided to have Tanner install the unit, which included all-new copper fittings and much more. This company knows water heaters, and I appreciate his honesty that he could install a tankless heater, but financially, the layout of my house would not be in my best interest. Therefore, I felt comfortable working with The Water Heater Company to install my new Bradford White gas tank water heater. Tanner was highly professional, cleaned up after the job, and went through everything he did installing my new tank. I highly recommend anybody looking for a tankless or tank water heater contact the Water Heater Company, and if youâ re lucky enough, Tanner will be your technician."

"Ruben is a great guy. We had issues with the first water heater (brand new). The manufacturer and distributor are not helpful in pinning down the problem â it took three weeks to finally fix the â brand newâ Bradford White water heater (I canâ t believe this). However, Ruben closely worked with me and spent lots of effort to get this done. I really appreciated his patience and effort. I will hire him again in the future."

"Mike came out and helped so much! He was able to diagnose a few things and gave us some great suggestions as to what things we needed to fix. Really loved the professionalism and expertise he brought. All the work was done quickly and efficiently. I'd go to Alpine plumbing again in the future, they do great work."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"More than exceeded my expectations. Very professional in every way from cleanliness to respectfulness. Needed a new water heater installed. Other companies wanted an arm and a leg while hermoso plumbing gave me a great deal with even greater service. In and out faster than expected with no hassles. Will definitely be giving them a call back for all my plumbing needs. Highly recommended."
