"I wanted to replace an out dated oil furnace with an efficient low carbon hvac system that heated my home in the winter and cooled it in the summer. I checked out Angies List for hvac providers in my area, made some comparisons, and contacted vendors. I chose N.E.T.R. based on the reviews on Angies List and the product presentation by the sales rep. for N.E.T.R.
The product performance,installation time frame, and cost matched exactly the proposal submitted to me by N.E.T.R. The technical support staff - Adam and Jose' - installed the Mitsubishi heat pump system with a professional skill level that I found to be reassuring. Russell Dodd, the sales rep., provided detailed support to my various questions. His attention to my product order-installation was more than I expected.
I feel confident that the product and services provided by N.E.T.R. will perform to my expectations.

"The company was professional and responsive from the consultation to the office staff to the various people who worked on our project. I had tried to contact about 10 companies to get our heater/ on demand hot water heater replaced. Addario's was the only one who responded immediately and was able to fit us into their schedule to get the work done. We had contact with at least 8 staff people in various capacities, and all were professional, polite and knowledgeable. We also appreciated the senior discount for our project and assistance with the MassSave rebate process.. It has been difficult for us to find service people since we move to Gloucester. We were surprised that the company services this area and we would definitely use them again for plumbing or electrical services."

"John “Johnny Rocket” & his associate did an amazing job servicing my home in Winchester. From the moment they walked through the door, they exuded a friendly, knowledgeable and professional manner. They were quick to diagnose the issue in my heating system & worked efficiently to fix the issue on the spot. The entire job was complete in under an hour. I needed a new thermostat & John installed one on the spot as well! I highly recommend hiring these two gentleman for any of your plumbing & heating needs. After the job was complete, they even took the time to talk my son & I about how they enjoyed helping residents in the local Winchester Community. (They are both former Winchester High School graduates.) I would give Johnny Rocket 10 stars ⭐️ if I could. Look No Further! -Emily (Long time Winchester Resident)"

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