“I am very satisfied with Alex’s service. He is very experienced, professional and courteous. Our 100-gallon commercial water heater didn’t work. He replaced the igniter and some other part for us. The problem was resolved. Thanks to Alex for his wonderful service!” ~ Mary C

Lucas’ clean up of the work area reflects both his commitment to performing excellent workmanship and to making his company’s reputation grow further.
I definitely would use Water Heater I my again and will be recommending them to others.
Chris Z was the technician, and he did an amazing job. I received a text notification when he was dispatched and was able to track his arrival in real time. He also called to let me know he would arrive in about 20 minutes.
Once on site, Chris inspected the water heater, provided a clear estimate, and patiently answered all of my questions. After I approved the pricing, he immediately got to work. The old water heater was removed and the new one installed within two hours.
Chris was professional, efficient, and very respectful of my home and pets. I would 100% recommend Chris Z and Water Heaters Only.
