"Dennis installed a new 75 gallon water heater and circulation pump in our home. His price was very competitive and lower than several other bids we got. He communicated with us well throughout the entire process. He worked around our schedule and the installation took only a couple of hours. The new water heater is working perfectly. I highly recommend Dennis and USA Water Heaters."

"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."

"Water heater went out on a Sunday and called Bill Metzger Plumbing around 6:30 expecting to leave a message. Surprisingly Bill answered the phone, I explained the problem and said he would send a technician out Monday morning. It appeared to be the gas valve. The water heater was 10 years old. Got 2 options, replace the entire water heater or just the gas valve. The water heater replacement was about $3000 and the gas valve about $700. No high pressure to replace the water heater. Decided the replace the gas valve after talking with the technician and Bill. Technician came out Tuesday morning and replaced the gas valve. Now plenty of hot water. The final invoice was $ 200 less than the estimate. Victor the technician was very professional. Knew what he was doing. I would highly recommend Bill Metzger plumbing for all you plumbing needs"

"The installation was very efficient and the crew did an excellent job in regards to the plumbing hookups and testing. I highly recommend this company and would use them for future projects. I want to comment that this job was in a second floor condominium with very steep stairs and no elevator. To those who wonder how a very heavy 50 gallon water heater is naviga!ted down those stairs without scarring the newly painted walls, l can only say they managed perfectly. No dings anywhere. Good job guys"
