"Matt called me back promptly with all information I needed to make a decision on new hot water heater. Matt and his colleague Sean arrived early, did work as discussed and cleaned up all areas and left area cleaner than when they arrived. I feel that job done well and I appreciated the honesty in his recommendations and what I needed. Would hire again and recommend to others"

"What a great guy! The furnace and the water heater went out at the same time. I was freezing! It was all sorted out the same day. Angel was able to remove my old water heater with a new one. I plan on hiring him again, Thanks, youâ re an Angel!"

"This is my sixth time using the service from Andrew at Local Plumbing and Heating. He is quickly available, efficient and thoughtful. He is trustworthy: I know he will take care of everything I asked for and thinking ahead for great ideas. I used his service for major home projects and I strongly recommend him for everything: from water heater tank replacement to gas lines installations."

"We found multiple issues with the heating system with our new house, and had to get a few service calls. We are glad to find Genove Oil & Air Co, they were very competent & professional, and fixed all the issues quickly and helped me understand the system better. Franco who does the scheduling is very accommodating, and kept me informed if the technicians were late. Frank and Richard (their Sr technicians) definitely know their stuff, and pleasant to talk to. This is a well run company and we would definitely use them again."

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