"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"I called Water Heaters Only out of desperation on Sunday...Seth @ toll free # was fully aware of our tenants being without hot water for 2 days and was able to get a technician out on Monday morning. Monday @ 5 pm, hot water was up and running. David, the technician knew what had to be done to get the heater up and running. The next day, we did have a hiccup with a part but David came out immediately and tweaked the part -- all is good. Here is what I like -- 1. no sales pitch. 2. David gave me a plan b for possible additional work. 3. this company is available 365 days and you dont have to wait for parts to be delivered from out of state. 4. Water Heaters Only has their own facility for parts."
