"They were very professional with a local visit to confirm the bid and scope of work. Their bid was very competitive, even one has to wonder what a water heater replacement cost today. The installer did a great job, right in time."

"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."

"Found me the right size water heater, a few days before Thanksgiving and had it installed within 2 hours. Clean and efficient and Bradford White gas water heaters are American made. Built to last. Daniel Westereng did a great job with the install. Clean, fast, thorough and polite."

"I would absolutely use Jax Mechanical in the future. Justin and Zac were very professional and thorough. I was very hesitant, due to a previous bad encounter with Service Master. Justin and Zac were patient and not condescending. Michael was quick with the bid/estimate and I am grateful for their service. If you need a water heater installed, be assured that Jax Mechanical is the only call you need to make."
