"I was very happy with the quick response I got. Within a few minutes of submitting a request for service, Jeff called. He was professional and accommodating. Our water heater broke and needed to be fixed before going away for the weekend. He was at my house the next morning and replaced the water heater in a few hours. J. Griffin employees are nice, respectful and explained what they did. I would highly recommend J. Griffin."

"We lost our boiler - and all heat – just one day before a major snowstorm was forecasted to hit. I reached out to Chris from Chris Vaccarello Plumbing to see if there was any chance he could fix our existing boiler before the storm arrived. After thoroughly assessing the condition and issues with the old system, Chris explained the problems clearly and offered to install a brand new heating system the very next day. True to his word, Chris and his team arrived promptly at 7 AM on the day of the storm. They worked tirelessly and with incredible dedication straight into the night, just to make sure we had heat during the worst of the storm. Their commitment, teamwork, and professionalism was truly impressive. I would absolutely hire Chris again and highly recommend him and his team to anyone in need of plumbing or heating services. Their reliability and work ethic are second and none."

"Spencer will, without question, exceed your expectations, particularly if youâ ve ever dealt with a contractor. Spencer Home Services repaired a failed heating system for me in a unit that I rent out. Every other outfit I called (at least 4 North Shore operators) was too busy, quoted a ridiculous price, or gave me ranges of times a day or two out to get a first look.. I get that heat problems happen in winter, but it is a true professional that is responsive AND follows through.. Peter came out, assessed the situation and impressed me w/ his experience, acumen and old school values. Rich and Reese made a sizable task seem like no big deal. Super respectful-that this was someoneâ s house without heat, not a job. Sheila was a delight to deal with in the office.. Everybody else told me it might take a week or more to complete, and they preyed somewhat on my sympathy for timeline flexibility. With Peter and company, it was one call and a major heat repair was DONE in a few hours. Responsive like Iâ ve never known, theyâ re experts with old school values, Youâ ll be pleasantly surprised by hiring Spencer Home Services."

"I cannot recommend these guys enough! I am not a patient person, when it comes to work on my house. They EXCEEDED my expectations! Their install was professional, well communicated, clean and efficient. Work was done while my twin babies were home, and they were incredibly accommodating. Their service people have been quick to reply to every question I have had after install was completed. I, honestly, will never have to shop around again - Comfort Professor will be my first and only call."

"I needed 2 backflow preventers replaced , a water heater repaired and a to0ilet repaired. I had a quote from a very famous local plumbing/heating company for $4000! I called Doug for a second opinion and he came in at HALF the price!! and that was AFTER I showed him the first quote! He didn't seem surprised at all about the first quote. Not only was he half the price but he pointed out that my 6 year warranty on my water heater had 6 months left and said I could get a new one thru that warranty for $100!!! He took care of going thru the company getting me the new heater. He completed the job in a few hours. I will NEVER call another plumber again! My recommendation is to run, not walk, to get Doug for your needs. On top of that he is so very nice. I would give 10 stars if I could."

"I submitted a request at 11am and they were at my house by 2PM starting the work. The two guys that showed up had everything they needed in the truck and were able to fix the leak and change out the valve in an hour. They also talked me through what the issue was and how to avoid it in the future. Incredibly helpful, punctual, and I'm very happy with the work done. I will definitely be using them in the future."

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