"My water heater died last week. I went on Home Advisor and received a number of calls. One from George at Stream Water Heaters. We discussed my problem. George requested Photos of the heater and the area around the heater. Within 30mins I received an estimate. The price was totally reasonable for equipment and install. The water heater from a well known company and carried a better than good warranty. I received an install time of 6pm next day. The team remved the old water heater, replaced an obsolete valve, and installed the new water heater. I had numerous questions. All my questions were answered in the most courteous manner. The professionalism, expertise, and timeliness of George's Team were exceptional. Highly recommend this company."

"Cody was prompt with his quote and kept in contact with me constantly. Our project was able to start weeks ahead of schedule and was completed on time and on budget. Multiple crews worked on our home across a week and a half. Each individual was professional and was more than willing to spend time explaining each step of the process. They cleaned up each day leaving the house in almost better shape than when they started. They also worked with us around accommodating our animals. Cody was able to adjust and respond quickly to change requests we had during the project and we could not be happier with the result. Post install Cody has been great taking our calls for questions on the new system and helping us learn usage of the systems. He even walked me through an easy change to the tankless hot water heater spending a good hour on the phone with me. Overall Cody and the team at SeaTown electric heating and air have been wonderful to work with and have exceeded our expectations with our hvac and hot water tank replacement. We will be using them again for future projects."

"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."

"Great. I received 3 bids and Drain Pro's was the most competitive and thorough. We scheduled a date, and installation was done in a day. They removed my old electric water heater and were tidy and very professional. I paid by check as they left. Now I will have to install an electrical outlet next to the heater but meanwhile, it's on an extension cord... Looking forward to 24-hour hot water, and a lower electric bill!"
