“I discovered our water heater was leaking and called Water Heater Specialists. They advised me how to shut it off and said they could come that day to check it out. After inspecting it, it was determined the unit needed to be replaced. Brian had everything he needed in his truck and everything was ready to go in a couple hours.”

The evidence — in reviewers' own words
Critical
“I had a new water heater installed about 10 yrs ago but the pilot light went off this morning. I read the instructions stuck on the water heater and it says to turn knob to clockwise to the pilot position and it would not ... so I called them and the person who answered was very rude and asked me to read instructions (in a very abnoxious way) or schedule service for $159 and not tell me that it should be done …”
Positive
“Brian was very nice. He did a great job! It took less than an hr and even took the old water heater away. So stress free for my dad.Who is 88. Thank you again Brian and happy birthday too!”
“They showed up promptly and replaced the new tank at once. The gas control wasn’t functioning properly and they tried to fix it. They come back next morning and change with another new tank and it is working now. Keeping professionalism and easy to talk is my favorite experience with them. Kudos to Sesak V.”
