"Excellent experience with Jacob and Blaine from Seatown. They piped a gas line over to the tankless water heater and installed the heater. They removed the old heater and cleaned up the area. The quality of the work was very high. Both Jacob and Blaine were very personable and polite. We have already booked Seatown to upgrade our electrical panel and replace our old knob and tube wiring and sockets. Highly recommend Seatown."

"From the free bid, to the actual install, I couldn't have asked for a more professional team - including the girls in the office (who were always friendly and kind). This is an A+ operation and I would highly recommend them to anyone looking for a repair or installation."

"Work was done quickly and professionally. Were very careful to collect and/or cleanup any water drips. Had to cut wall board in laundry room to repair hose bib. Removed as small a piece as possible and replaced when finished."

"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."

"We had Washington Energy Service install a new furnace, air conditioner and hot water heater when we purchased our home in 2016. We were impressed with the presentation made by their representative prior to our purchase compared to other representatives with whom we spoke. Because we wanted to be insured, we purchased an extended warranty. We're really glad we did! We have had the system serviced annually, but this year an extensive leak developed that damaged the interior of our home and caused black mold. We initially notified our insurance company but then decided we should notify Washington Energy Service as well. The decontamination had begun, but the damage was evident. The Washington Energy Service representative was so very helpful and understanding. He immediately determined what needed to be done to correct the problem and within two days had a team to our home to complete the repair. We appreciate the professionalism, courtesy, honesty and rapid response with which Washington Energy Service treated us and would strongly recommend them to anyone looking for a good local company. Linell and Bruce Arbuckle Federal Way, WA"

FAQs for water heater repair or service projects in Oak Harbor, WA

Warning signs include fluctuating water temperatures, a pilot light that repeatedly goes out, unusual noises from the tank, or complete heating failure. You might also detect a rotten egg smell, indicating a potential gas leak, or notice water that never reaches the proper temperature. If your water heater is over eight years old and displaying these symptoms, the gas valve is a likely culprit. Professional inspection is recommended, especially if gas odors are present.

Water heater gas valves are not universally interchangeable. Each valve must match your specific water heater's make, model, and specifications. Important compatibility factors include gas type (natural gas vs. propane), BTU rating, connection types, and physical dimensions. Using an incorrect valve can result in poor performance, premature failure, or dangerous gas leaks. Always consult your water heater's documentation or a professional plumber to identify the appropriate replacement valve for your unit.
