"Shawn performed the annual heating inspection for our furnace/oil tank. As always he was very quick, and took extra time to walk me through the piping of our different heating zone. Highly recommend Genove Oil, they are providing stellar service and with employees like Shawn you are in very good hands."

"Replaced a tank water heater, the door was too narrow so first pitched removing framing with no guarantee that it’d be replaced correctly. I suggested using a smaller sized unit based on a quote from another plumber which is the route we went. They also covered the overage for the additional cost of the smaller sized unit which was nice but if I wasn’t aware of the option I’m not sure what I would have done. They also only sent one person initially so I helped bring the old unit down and the new one up in between trying to work. Also the breaker to the hot water heater was never flipped back so I’m waiting to see how the unit performs now."

"Hello, Yellow Dog Home Services was phenomenal! Jeffrey was able to come the same day, complete an assessment, and define the next steps for the installation of a new hot water heater the following day. He is very personable, professional, knowledgeable and affordable. Yellow Dog is now saved in my iPhone for future project needs! Richard"

"They installed a very complex Bosch Combi furnace and water heater. The precision of the work and the end result was excellent and frankly was very close to a major work of creative art! They did a great job."

"I recently had a new heat pump system installed by Trust 1, and the entire experience was outstanding from start to finish. Their team was professional, knowledgeable, and respectful of my home. The installation was smooth, on time, and the system is running perfectly. It’s rare to find a company that truly lives up to its name, but Trust 1 absolutely earned my trust. I couldn’t be happier with the service and results — highly recommend them to anyone needing HVAC work!"

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.
