"We had The Water Heater Company come out to service a Navien Tankless Water Heater and the experience was excellent from the initial call to the same day service and completion of job. Our technician Leo was fantasitc - friendly, knowledeable and fast. Truly an expert, he was quick to connect with the manufacturer and identified a few issues from the original installation from another company that were not up to code. He provided an estimate on the spot and had all the tools and parts necessary to complete the job. I highly recommend this company and Leo."

"I returned home from a trip and found water all over my downstairs bathroom and adjoining shed. It was late afternoon and I called Western Rooter who agreed to come out first thing the next day, I had a pretty sleepless night. Rene showed up the next day and assessed the situation and started clean up. Tony soon joined him and the two worked all day until after dark and helped me with cleanup and putting things right. They explained to me what they were doing and why along the way. I felt they charged a fair price. I am so grateful for their service and highly recommend Western Rooter."

"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."
