"My water heater tank stopped working so I decided to convert to a tankless system. Chad and George were who I worked with. I had a great experience with both of them. I was very pleased with their knowledge, work, communication and help. I would highly recommend them to other house owners. "

"They came out quickly to give me a estimate for replacing my 10 year old Rinnai heater. They actually told me NOT to get the additional optional recirculating feature that another company was recommending, due to cost and reliability issues. When Washington Water Heater’s bid came in it was about 40% less than the other guy for the same work and same water heater (minus the recirculating feature)- $5200 vs $9100. They didn’t require any money up front (other guy wanted 50%) and were able to schedule the work for only a few days out (other guy said it could be weeks or months). The showed up on time, did excellent work and even charged me slightly LESS than the original bid because they ended up not needing to install a pump for the condenser."

"Shad went above and beyond today. The water heater I had purchased would not fit in my tight spot. Shad put it in his van and helped me return it and get a replacement. The work was done in a timely manner and neatly tidied up. I will definitely use Kingdom Plumbing for my kitchen remodel and future needs. Highly recommend!"

"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."

"My extended family always use Bob Larson Plumbing for all non-DYI plumbing projects. The prices are fair and they don't talk you into things you don't need. The staff is friendly and professional. Our recent water heater installation was a little difficult due to the age of the original heater and plumbing. The technicians worked diligently to figure out the problems which, ultimately, required an electrician and came back as soon the electrician had replaced a breaker. Don't hesitate to call Bob Larson Plumbing!"
