Tony called back immediately and scheduled service for our Navien the next day. The team also changed a whole home water filter at the same time. The service was also priced very reasonable.

I just love Dr. Water Heater. A couple years ago they replaced a broken water heater and this time they redid an ice maker connection for my refrigerator. They are excellent workers, very reliable, return phone calls (so important), clean up when finished, and very friendly. They do MORE than water heaters. Tony is the best!

Tony is the man! He was able to configure my water heater problem and was able to access the warranty from Rheem to get me a brand new water heater for free! He is the go-to for water heater needs! Definitely have him saved as my plumber contact for sure! Look no further! Great price!

I called the Doctor Water Heater yesterday after finding my hot water heater leaking all over my basement floor. Tony came out quoted the job immediately, detailing all aspects of the work. By 4pm the work was completed and Tony took his time to review the new system. The quote matched the invoice. He is highly knowledgeable and skilled and I deeply appreciate his professionalism.

Hot water heater was leaking. I put out a cry for help on home advisor and he called in 5 minutes. His professional and calm demeanor eased my tension. He arrived first thing in the morning and within 3 minutes knew what was wrong and why. He replaced everything, got the system up to code, which included having to make a 4 circle in BRICK! Because Ima Nurse did a lot of above and beyond extras for free. The entire job was done before my kids had to start school! You simply wont find better than him. Thank you so much! Forever grateful, Sara
