"Absolutely Fabulous! Great service and very reasonable priced. We replaced an old 14-year Noritz tankless with a new Noritz tankless and this company is top notch. From the folks answering the phones (Nicole) to the on-site technicians (Evan was great), we received 100% fantastic, reliable, and fast service. Anthony spent 30-45 minutes on the phone discussing various model options before Evan arrived to take photos and assess the installation. Evan then presented us with clear bids for 2 different model options and returned with a colleague to install the new unit 2 days later. We would recommend this company to anyone wanting a tankless water heater. We also liked how the bid and invoicing process was handled 100% electronically. We also received texts and emails reminding us of the appointments and techs pending arrivals. 5 stars all around!!"

"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."

"100% recommend. Very professional in every way as the other reviews say. Geremias and his nephews installed a tankless water heater for me, and it works great. Punctual, responsive, communicative, trustworthy, and the best price. I couldnâ t ask for better."
