For emergency services, please call 781-933-6387. N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we’ve installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers’ needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

We are a full service residential construction and remodeling company. Our goal is to exceed all of our clients expectations through exceptional customer service and quality craftsmanship. We work with some of the best tradesmen in the industry to deliver a quality finished product. From deck and porch builds to siding and windows, we can do it all. Contact us for an estimate on your project today! Check out our instagram for photos and updates @coenconstruction

"I recently hired Coen Brothers Construction on a thorough bathroom renovation, and the outcome was outstanding. Their quality was excellent, and I am delighted with the final result. Their sub-contractors were also great and worked at the same high standards as the Coen Brothers. Although we faced some communication issues at the outset, we eventually worked through them, and it significantly improved throughout the project. They paid attention to detail; when my project manager saw me stripping the trim for reuse, they recommended buying new trim and a lumber yard to get it. And it makes a big difference having new trim with clean, sharp lines. Their tile work took longer than expected, but the miter cuts the trim cuts, and the finish is excellent. They were consistently punctual, respectful of my home, and very tidy - tidying up at the end of each day. While the project took longer than anticipated, the reasonable cost and the team's meticulous attention to detail compensated for it. Coen Brothers Construction also expertly handled all necessary permits and inspections, keeping me informed every step of the way. Overall, I am satisfied with their work and would hire them again for my next project."

"I highly recommend Sanfer Rocha and D.S. Partners Construction for a bathroom remodel. Sanfer was professional, transparent with costs, and responsive to questions during the whole renovation process. His workers were skilled, prompt, and friendly. Sanfer also suggested vendors and provided helpful tips. I am very happy with our beautiful bathroom and would hire him again for another renovation."

Unique Indoor Comfort, an Ace Hardware Company is a family owned and operated business with over 30 years in the HVAC industry. Providing residential heating and air conditioning maintenance, repair and installation of furnaces, boilers, heat pumps, ductless and high velocity AC. We are experts at providing air conditioning solutions for older homes, oil/gas to heat pump conversions, and are Mass Save certified heat pump contractors. We’ve built a reputation for superior quality, through years of putting the customer first and getting the job done right the first time. As local residents, our family and expertly trained team of technicians think of our customers as neighbors; our goal is to maintain our reputation as a quality organization, continuing to offer superior heating and cooling services in the Boston area and ensuring that you can be proud of our work and products for years to come.

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

Boiler Repair questions, answered by experts

Regular inspections, cleaning, and checking of exhaust systems maintain safe operation, ensuring efficiency.

One of the most common signs you’re dealing with a bad thermocouple is the pilot light for the water heater will continuously go out. For example, you may light the pilot light and then have to re-light it a few days later. You can also look at the thermocouple for a visual inspection. If you notice discoloration, cracks, holes, or other damage, then you know it needs replacing.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.

Many states don’t have specific license requirements for HVAC repair companies, but your local city or county might. You can check online for local requirements and then Angi’s contractor licensing tool to see if the company you’re considering is licensed. Regardless of licensing, you should ensure your company is fully insured. We recommend checking to see if the company holds third-party certifications, including North American Technician Excellence (NATE) certification and R-410A certification, which qualifies your provider to work with HVAC refrigerants.

HVAC quotes may be negotiable. It’s important to be upfront about what you need, your budget, and your expectations. However, your contractor must suggest repairs or the system they think is best for you, and those things may not be negotiable. So, when can you negotiate an HVAC quote? When installing a new system, you may not need to replace ductwork or install specialty items such as whole-home air purifiers. If your contractor is bidding on those items or others you don’t need or want, ask them for a quote on only the equipment and services you need.
