"Eric Mouradian (owner) responded promptly to my request for urgent replacement of a newly-broken hot water heater. He showed up on time, provided outstanding service, cleaned up after the job, and charged a reasonable price. Highly recommended!!"

"We were very pleased with the work that the Genove technicians did. They removed our 40-year-old gas boiler and associated water heater and replaced it with a new system. They tested the new system carefully, put explanatory tags on all of the relevant pipes and faucets, and cleaned up well. The team members were polite and worked hard. We had similarly good experiences when Genove technicians came to repair our central AC system. They were knowledgeable and efficient, got the system going again, and the price was fair. We continue to use this company for heating and AC repairs."

"David helped me install Heat Pump Water Heater that I purchased from Home Depot. It was his first time installing a heat pump water heater but he made sure it gets installed as per code and right way. He worked with me to install stop valve in the end."

"Steven showed up and was able to repair our AC after two years of multiple repair companies that could not help. Everyone else said we had to replace when Steven was able to determine that it just needed a quick repair. He was professional and so pleasant. English is not our first language but he was so patient with us. Highly recommend!"

"I had an incredible experience. My water heater was leaking and ready to let go. Brian had contacted me. He set up an appointment the next morning. The two gentleman ( plumbers ) came in. Removed the old water heater. Installed the New water heater. And updated the vent piping because it was old and out of code. They did a wonderful job. And I cannot speak highly enough of them , the speedy work and their professionalism. I now have a new plumber for all my plumbing needs. Thank you."

"I couldn't recommend these guys more. We had a 21-year old boiler replaced and upgraded, and a new hot water tank installed. I can't think of a single way they could have improved the whole process. From start to finish, they were knowledgeable, on time, clean, considerate, extremely professional and they did exactly what they said they would. The also installed a temporary hot water tank and left electric space heaters on the one night the burner was out of service. Everything is now working as they said it would, and a big bonus is their workmanship actually LOOKS great too! A+++"

FAQs for water heater repair or service projects in Sudbury, MA

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.
