Customers say: Quality work

"Mr. Floros worked with my schedule on a short timeline to replace our water heater. He professionally negotiated with me about how to get the job done approximately the way that I wanted while still meeting local code. When the job was completed, he cleaned up and took away the old unit. The price was a great value considering the work done."

"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."

"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."

"Sila Heating and Air Conditioning is the only service I found that can service my Buderus oil burner. John was the tech this time and he did an excellent job of taking care of the burner and then explaining the problem that arose with my chimney liner. Since I didn't have heat or hot water until the liner was fixed, I had to use a company I didn't know as an emergency repair. I was able to speak with their tech using the information provided by John and therefore felt comfortable with the costly repair. John even came back after his last call to turn the burner back on. I have the warranty on my burner so I pay a discounted price and have the coverage if I need it."

"We have been using them to maintain our AC for a couple of years, and they are always extremely professional, thorough, and honest. We started having major problems with our unit last summer, and they determined that we needed a major repair to our outdoor AC unit. We were dreading the potential cost, but they were able to do the job, and do it extremely well, for much less than we anticipated. I would highly recommend their services!"

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