"Water Heater Masters were top-notch! I called on a Saturday afternoon - they were available 9am Sunday morning to come and inspect and quote. They only had one guy working that day, but scheduled me for Monday morning between 8 and 9. At 8:15am I got a call with an ETA of 8:45, which was a really nice touch! Despite telling me it would take an entire day to install, they were done by 1pm. They also found some creative ways to do the install to avoid drilling through my stucco (for the exhaust vent and for the condensate run-off). Very professional and clean-looking install. These guys may not always be the cheapest around, and they recommended a top-of-the-line heater (which is what I really wanted anyway), but I'd much rather pay a little extra for that level of service and support. Thank you!"

"August 25, 2026 Rated 5/5, I am writing to express my appreciation for the excellent customer service provided by Horacio Parker, a plumber with Beutler Air Conditioning and Plumbing. On August 25, 2026, water was leaking from my water heater onto the garage floor. Mr. Parker responded promptly, listened attentively, and showed patience, empathy, and understanding of my concerns. He was courteous, polite, friendly, and maintained a professional, positive attitude throughout the service call. Mr. Parker shut off the power and water, drained the old 75-gallon Bradford White water heater, and installed a new 75-gallon Bradford White Energy Saver water heater. He communicated clearly and showed me how to shut off the water to the house and turn off the water heater to help prevent future flooding. Mr. Parker is an asset to Beutler Air Conditioning and Plumbing, and any company he provides service to Lovevasia Bey"

"The plumber came almost at the end of the appointed time. When he arrived, he was fairly arrogant, and refused to negotiate despite coming from Angie's list. Lastly, he repaired the leaky line in about an hour, charging $530, and also did not provide the water plastic box for water line. We had to purchase one from another store. When I paid for the invoice, they didn't tell me that they are charging additional 3% with credit card. All in all, they did the work, but at a high price, and so so customer service."

FAQs for water heater repair or service projects in Fairfield, CA

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.
