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."
