"Call in the morning, visit that afternoon with quote, installation next day. They didn't have our model in stock, so we got an upgrade to the next larger water heater at no additional cost. Installer was very knowledgable and friendly."

"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."

"We had a water heater break down during the holiday break. Chandler and his crew were able to respond and replace the water heater asap. Chandler explained that we had a large capacity water heater - 75 gallons and it would be more expensive, but we found their quote was very reasonable. They came and replaced the water heater and were very professional. I would highly recommend them and would gladly use them again. Thank you Chandler for such prompt service and great work!"

"The first visit lead to cleaning the area around the heater and burners and checking the thermocouple. Sadly that seemed to make it worse. Less than a week later No hot water for over 30 hours till the second technician replaced the thermocouple. All is perfect now. No charge for the second visit. The next step, if needed will be a tankless and their quote looks a bit steep. But I am really hoping I won’t need to go that far."

"Jesus repaired the leaking water pipes behind the shower valve. It was Sunday, but his response was quick and he showed up on time. I think he is the best honest plumber I ever met. He did a great job with reasonable price."
