Eight months for a job quoted at two: that is how a May 2026 Angi review sums up a heat pump installation on a triple-decker by N.E.T.R. Inc., a North Andover heating and cooling company. The customer put the project at about $107k and wrote that the original electrical design violated Somerville setback code and needed a complete redesign, that the electrical failed inspection multiple times, and that NETR pressured for payment before inspections. After NETR gave a 24-hour ultimatum to accept $1,500, the customer settled to avoid further hassle. The heat pumps work now, the same review says. The other recent account runs the opposite way. In an April 2026 Angi review, a customer had maintenance done on a heat pump and mini splits and said Rafael Guzman explained everything he was doing clearly and gave pointers to maintain the system. In a 2025 Angi review, a homeowner who met 3-4 other vendors chose NETR. That customer said the salesman, Mark, arrived on time and gave a competitive quote before he left, that NETR offered a 5-year 0% interest loan through GreenSky, and that installation took only a few days to schedule. The installers put in the electrical components, compressor, branch box and 5 heads, and consolidated and hid the lines on the outside of the house. The older accounts are brief. In a 2022 review, a customer called the person who came for routine HVAC maintenance punctual, professional and friendly. In another 2022 review, a customer said they got the air conditioning running, but a water leak remained that the customer had someone else fix. On its Angi profile, the company says it has installed heating and cooling systems in Boston and its surrounding areas since 1989. A privsource.com item reports that Sila Heating and Air, a Dubin Clark-backed residential HVAC and home services platform, completed an add-on acquisition of N.E.T.R. Inc.
“Sila Heating and Air, the Dubin Clark‑backed residential HVAC and home services platform, completed add-on acquisitions of N.E.T.R. Inc. (North Andover, MA) and John S. Parker Home Services (Kingston, NY).”
NETR (now Sila/Goldman Sachs) heat pump installation on triple-decker. ~$107k, quoted 2 months, took 8 months. - Design Error: Original electrical design violated Somerville setback code. Required complete redesign, ~7 week Eversource resubmission delay, neighbor coordination. I had to personally intervene with Eversource management. - Failed Inspections: Electrical failed multiple times. NETR pressured for payment before inspections citing "substantial completion." - Settlement: After 8 months I requested compensation. NETR offered $1,000, blamed delays on "my preference" not their design error. When I provided documentation proving otherwise, they withdrew offer to send foreman, gave 24-hour ultimatum to accept $1,500 or face "legal escalation." We settled to avoid further hassle. Outcome: Heat pumps work now. But design error, failed inspections, gaslighting, and 4x timeline make this impossible to recommend. On $100k affecting three households, expected better.
Had maintenance done for heat pump & mini splits. Rafael Guzman is was professional and knowledgeable . He explained everything he was doing clearly and gave pointers to maintain system. Would definitely recommend N.E.T.R / Sila
From start to finish, NETR did a fantastic job. I met 3-4 other vendors, and they didn't come close to NETR's responsiveness, professionalism, or timeliness. NETR earned my business before I even got a quote from some of the others. The salesman, Mark, arrived on time, was respectful & attentive to what we needed, explained our options well, and provided a competitive quote before he left my home. NETR also offered a 5-year 0% interest loan for the project (via a relationship with GreenSky). It took only a few days to schedule installation. The installers were prompt, professional, respectful of our property, and did an excellent job installing the electrical components, compressor, branch box, and 5 heads. They did a nice job of consolidating and hiding the lines on the outside of the house. This past year, we've worked with many contractors, some good, some terrible, so I can compare. NETR was one of the best, and I would hire them for my next project in a heartbeat.
The person who came for routine maintenance of my HVAC system was rgreat: punctual, professional and friendly.
They got the air conditioning running but there was still a problem with water leaking which we had to have someone else fix.
