"Our water heater broke over the weekend (of course...) and RJP answered immediately to my Angi request. Other companies are calling me all day on Monday to offer to start quotation process, while I had a new water heater installed by lunch time on Monday. Quick, clean and professional service and competitive price."

"I purchased a heat pump electric water heater to take advantage of a generous rebate from Efficiency Maine. When looking for someone to install it I was referred to Jophil by a real estate company that I know. I called and was given a time that Kyle would arrive to give an estimate and perform the installation (if the estimate was accepted). I did accept the estimate and Kyle got right to work. He did a nice job and made sure that everything was in good working order before he left. I was very pleased with my first experience with this company and would not hesitate to call on them again in the future."

"I had a great experience with this plumber! He arrived right on time and was very professional and friendly from the start. I had a leak in the plumbing in the wall between the bathroom and the bedroom and he took the time to explain exactly was going on. He even went under the house (in the cold and dark) to inspect the issue further and took pictures so I could clearly see the problem myself. He explained the repair in a way that was easy to understand and fixed the leak quickly ad professionally. I really appreciated his honestly, communication and the quality of his work. Everything is working perfectly now! I definitely would recommend him and would happily call and refer him if I ever need a plumber's help!!"

"Mike is an excellent, friendly, and extremely knowledgeable plumber. I'll definitely be contacting him for future plumbing issues. The new water heater went in quickly and properly, with a few laughs here and there."

"Can I give an "A+" rating? Reached out to a handful of HVAC contractors to get a quote on replacing my 20 year old central air system. From the woman who I initially spoke with to the guy who came out to give me a quote (who happened to own the company) to the crew that came out to do the project, I got first class service. I scheduled the initial visit and Joe arrived 15 minutes early. He gave me a handful of quotes and was very clear on the differences between the systems. I settled on one of the lesser priced systems and never felt like he was trying to "up-sell" me. In fact the system I purchased qualified me for a rebate from my energy provider. I was able to schedule the install for 2 days later and again, the team showed up right on time. The guys were personable, respectful of my home, and very hard working. I have a brand new central air that seems to be working perfectly. It's significantly quieter than my old system. They cleaned up any mess that was made and gave me a complete walk through of my new system. I could not be happier."

"I felt the tech was taking advantage. Quoted a price to replace motor $400 vs. fix brushes on a motor. (less than $50) I did not hire them and searched for another reasonable service repair Co. willing to do the repair."

FAQs for water heater repair or service projects in Newmarket, NH

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.
