My water heater was leaking and growling. Who do I call to replace it? A plumbing firm? If so, which one? I ran across The Water Heater Company and figured a firm that specializes only in water heaters should be a wise choice. Right? My decision turned out to be a good one. They are so responsive and professional. The price was fair and reasonable. Top quality USA made water heater unit was installed. The workmanship was superb. Effective communication from start to finish. Terrific overall experience!

Always have a great experience with this company. They are professional, prompt, and explain services well. Would recommend highly.

Mitchell arrived on time, provided expert advice, and had all necessary hardware to complete the job efficiently. After discussing options, he replaced my faulty pressure regulator and valve, resolving the issue immediately. His organization, efficiency, and cleanup were outstanding. As a certified Safety Engineer, I can attest that Mitchell’s workmanship and customer care are among the best I’ve seen.

The Water Heater Company is very reliable and works with its customers to achieve the best possible outcome. Everyone is extremely helpful, kind, personable, and made sure I could get the water heater I desired at a price that I could afford. My technician, Evan, made sure that my house was in perfect order before and after installation, which was almost 3 weeks apart. Evan walked me through the new system with ease and professionalism that other usually do not take the time to do. I’m very satisfied with my purchase and everyone involved. Thank you for everything. I’m only sorry that I didn’t think to take a photo of Evan and his wonderful work!

Words cannot express my gratitude. Evan and his team did a superb job coordinating and installing a brand new tankless water heater for our family. We are so grateful with the amazing service, professionalism, and attention to detail that was given. Highly recommend! Thank you Evan!

Can’t say enough positive things about this company. I called several companies and The Water Heater Company responded within minutes. The other companies called me more than a day later. They let me know when the repairman was going to be here and sent a pic so I knew who he was. Their office staff was excellent in all ways. They are the front line to any business, and they are amazing. A real asset to this company is Evan. He was extremely knowledgeable and professional. He knows his business. He kept us informed every inch of the process. We couldn’t of asked or gotten a better person. He had to clean up the mess the last person created and explained everything to us that was wrong. We will be returning customers for sure!

We recently had TWHC replace a tankless water heater in one home and two tank water heaters in another. From the service staff to the technicians on-site, everyone was a pleasure to work with—timely, efficient, and organized. The quality of the work was flawless. We’ve also used TWHC for service work and have been consistently impressed with the craftsmanship and job quality.

A special shout-out to Billy, who provided excellent phone support. He was courteous, helpful, and made a lasting impression. Thanks to him, we’ll continue to choose TWHC for our future needs.

I recently hired The Water Heater Company for a tankless water heater installation, and Evan did an excellent job. When it came time for the descale service, I requested him again. I also decided to install the Halo filtered water system, and Jake was incredibly helpful in guiding me to the best solution for my home.

The company’s customer service is fantastic. They kept me updated on Evan’s arrival, and I was happy to see him again. He’s always kind, confident, and ensures everything is done right, even with complex installations. I’m very satisfied with their service, products, and overall experience. Thank you!
