"Robert was very responsive to my request for a water heater replacement. His pricing was competitive, and his crew was prompt and professional. The work was complete less than 24 hours after first contact. I recommend Robert Johnson Plumbing and plan to be a repeat customer, myself"

"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 am a big fan of Heritage. We needed to replace our broken furnace and I got quotes from five different HVAC companies, all of which had many 5-star reviews. Heritage was the best, by far, for a few reasons: Dexter, the HVAC project manager from Heritage, was professional and patient. He answered all of my questions, applied no sales pressure, helped me customize the job to my budget and needs, and even brought us space heaters to keep the house warm since we had no heat in winter. Heritage was one of only two companies to actually take detailed measurements of my home before recommending a furnace size and submitting an estimate. Three of the companies just eye-balled it and recommended furnaces that were twice the size of what Heritage recommended. Some of them told me I had to replace my entire heating and cooling system or I would have major problems (which Dexter debunked). If an HVAC project manager does not bother to measure your house before recommending a furnace size, you should be concerned. Dexter helped me every step of the way with the HEAT loan and furnace rebate process. Dexter worked around my busy work schedule and communicated in person, phone, email, and text, depending on what was best for my workday. After the furnace was installed, the house got uncomfortably dry and we realized we needed to add a whole-house humidifier (which Dexter had recommended originally). Heritage was able to come out the morning after we called and put in a humidifier and the house was comfortable within a day. The Heritage install and service guys (Fran, Bob) were professional, patient, and courteous from start to finish. The installation site was clean and well-labeled. They checked in with me and explained important items along the way. The Heritage office staff are always reachable and helpful with any scheduling, billing, or follow-up questions. The only drawback is they are definitely a premium brand and charge on the higher end for their work. They quoted higher than any of the other four companies. That said, I was able to negotiate the price and I was happy to pay a little extra for a job well done, a strong warranty, and professional service. Honestly, Heritage won me over and I will only use them in the future for my HVAC needs. They were transparent and professional and I never felt like I was getting hustled (unlike a few other big-name brands). Now I recommend Heritage to everyone I know."

"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 specified that it was a tankless water heater, yet not surprisingly I was referred to a plumber who didn't know anything about tankless heaters, resulting in a waste of a couple of days. The second person did know about them, and so far the repair is working (fingers crossed). I wish CHW would pay attention to the details in my claim."

"The gentlemen who sell the product were excellent.  Punctual and answered our numerous questions.  The installation was timely and the laborers were great.  That's where the good stuff stopped.  First of all, there were scuffs all over the ceilings and a hole in the sheetrock where they had dropped a tool in the attic.  Secondly, the installation of the ac grates was shotty at best.  We had to take one down and realized they were only screwed into the sheetrock no strapping or molly bolts.  The biggest issue however, is that we have been without heat on three occassions, had zones running continuously, and had no less than five service calls to them.  We are beyond frustrated after spending so much and are still working to rectify the issue

I have updated our review.  After the last service call, the problems with the furnace have been fixed.  I believe they are now working with a different installation company which should match with their customer service end of things (which as i said was always excellent) we are still waiting for them to come back this summer to complete a few odds and ends and as soon as that work is completed i will give a final review

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