"Austin with Twin Water Heater did an amazing job converting our traditional tank water heater to a tankless system. He was knowledgeable, professional, and took the time to explain the entire process and answer all of our questions. The installation was clean and everything turned out great. I especially appreciated how transparent he was about the work that needed to be done and the cost—there were no surprises or pressure to add anything unnecessary. You can tell he really cares about doing the job correctly and making sure his customers are happy with the end result. We’ve been loving the tankless system and having endless hot water! I would absolutely recommend Austin and Twin Water Heater to anyone looking for a water heater installation or tankless conversion."

"I purchased a new Navien NPE-240A2 Tankless Water Heater and had it installed. I'm loving the new water heater. It replaces an old Noritz tankless that died just before this installation. The on-site estimate was what sold me. Ken went through all the details and answered a lot of questions from me. Zachary came out with Austin and performed the installation just like I discussed with Ken. Zachary kept me in the loop throughout the installation to ensure I was in agreement with how it was going. Zachary always had my interest at heart and ensured no corners were cut. The installation is much cleaner, and more correct than the previous tankless company did. Zachary even listened to my concern about the astectics of the exterior exhaust and quickly found an easier and cleaner looking way to address my concern. He also removed an old recirculation pump and replaced a new main house shutoff valve. The entire area was treated respectfully and left cleaner than they found it."

"Installation went smoothly once the particular part we needed arrived. We were impressed by the care Devon took to consider our scheduling needs so that patient care wouldn't be interrupted during installation. He also made sure to install a mixing valve that prevents the water from being too hot for our young patients."

"They were on time. They explained why the old water heater leaked and how they brought the new one up to code. I now better understand my water heater. It also looks great. I'd recommend them to anyone. They will get it done right, and only right."
