"Robert Johnson was so helpful in discussing the h/w heater installing and the venting requirements. His price was so much better than others companies in the area. His crew for the actual install was as also great! Kevin, the crew leader, explained how everything works and the cleanup was perfect!"

"We recently had NETR install a ductless system in our single family home, and the entire experience working with NETR was consistently impressive. At every stage of the process the folks at NETR were super responsive and helpful, and their professional approach resulted in a zero surprise and zero problem experience. After initially reaching out to NETR to inquire about their services they setup a consultation visit. Russell Dodd arrived to review our property, listen to our needs and concerns, and recommend a solution. Russell is a friendly guy with many years of experience with ductless installations and had all sorts of clever suggestions on how to make this installation work best in our home. It's worth noting we also had 2 other top rated competitor firms visit to conduct property reviews, and the people that showed up were significantly less experienced than Russell and clearly did not have the product knowledge or range of ideas that Russell shared during his visit. Within days of Russell's visit we had an installation quote/estimate in hand and after sorting out a few details with NETR we scheduled an installation date. The contract covered all the items we had discussed with Russell and was very straightforward. The NETR price was competitive and in the same ballpark as the other companies – but with far superior follow-up and consultant services. There were no surprises or unclear items listed on the NETR quotes, while the quotes we received from the other companies had some areas where costs were not entirely clear. On the day of the installation Jerry Odom arrived and was the technician assigned to lead our project. Jerry was super friendly and carefully took the time explaining his installation process, listened to and answered any of our questions, and immediately went to work. Over the course of the 2 full day installation Jerry quietly and skillfully pulled everything together and made sure the units were placed exactly where we had requested. He did an exceptional job hiding piping and basically making sure that the new units throughout the house were installed in a very clean looking manner. Jerry was joined by two colleagues at various points during the installation and all were equally competent and skilled professionals. From initial outreach to the final day of the installation we interacted with at least 5 different people from NETR. The staff working back in the office were also very professional and helpful at all times. We interacted with Eleni and even one of the owners at one point when calling to confirm installation dates. This is obviously a company that values taking great care of the customer and sets an expectation that their staff are all honest, helpful, responsive and fair in all interactions. NETR deserves all the superlatives that are used to describe their people, processes, and services. This is a business that clearly makes it a priority to take care of the customer and deliver top quality work. We are very happy that we chose NETR over other vendors and would recommend them to anyone looking to install a ductless system."

"Daigle were quick to reach out to quote me for the work we needed - replace a water heater and arrived early! Very personable, professional. However, pricing was an issue. They were way outside of what other plumbers charge for this service and way outside of what Angi's has listed as average project costs. They did have an opening for next day installation which would have been fantastic but I couldn't justify the additional $2400."

"They installed a very complex Bosch Combi furnace and water heater. The precision of the work and the end result was excellent and frankly was very close to a major work of creative art! They did a great job."

"?I couldn't be happier with my new water heater installation. The team was professional, punctual, and incredibly efficient. They took the time to explain the new unit's features and ensured the workspace was spotless before leaving. ?It?s a relief to have hot water back with zero stress. If you need a reliable install, I highly recommend Expedition!"

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