"Our tank water heater went out. Since it was 14 years old, we decided to get a new tankless water heater. USA Water Heaters was very responsive when we requested a quote. We received a couple other quotes, and they were pretty similar in price. We went with USA Water Heaters because they were the only company that told me about the rebates offered by the gas company. They provided all required documentation, without my even having to ask for it. The others were not even sure there were any rebates available. USA Water Heaters arrived on time, completed the job in the time they promised, and did a great job of cleaning up when the job was complete. They were very professional. I would definitely use USA Water Heaters again definitely would recommend them to anyone that needs a new water heater."

"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."

"I turned to Angi's List for a 2nd quote on my water heater replacement after reading the reviews on the company my home warranty sent out. Carter came on time, explained the estimate to me for a Bradford-White double insulated 40 gal water heater and installed the same day. The estimate was slightly under the other company and I was able to get a $650 buy-out from my home warranty to put towards it. This was 3 months ago and I'm just getting around to the review. These guys know what they're doing and are very professional. Highly recommend!"
