"G&C made replacing our water heater super easy. They came out the next day, got everything swapped out fast, and handled the whole job smoothly. The crew was friendly and did the job right. I was happy to see they added some extra shutoff valves that the original builder had skipped. I like having the peace of mind that I could shut it off more easily in an emergency now. The new water heater works great and the process couldn’t have been simpler. Will definitely be calling them again for future projects."

"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."

"I hired them for a plumbing project worth $2,500 (that option wasn’t available in the dropdown list), and the experience was excellent. From the front desk to the plumbers, everyone responded promptly and professionally. I had the chance to interact with several crew members, and each one showed genuine care and a strong commitment to customer service. The plumbing team did a great job—I would highly recommend them."

"Addario's Services did a great job installing a new high efficiency combo boiler in our home. After I requested an estimate, I got a quick call from the office to schedule a time for one of their comfort advisors to come out to our home. Sam, my comfort advisor was very knowledgeable, and I appreciated his low pressure presentation. Once the work was booked, because our installation was complex, Joe came out and came up with a plan to vent the exhaust on the side of my house to minimize the number of pipes on the front of my house. The installation went very well, and they installed a temporary water heater so we were only without hot water for less than a day. For the day we were without heat, they brought in plenty of space heaters to make us comfortable for that night. When the installation was complete, the installation technicians took lots of time to explain the operation of the new system, and to answer any questions I had. The system is working great and there have b"

FAQs for water heater repair or service projects in Dover, 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.
