"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."

"No invoice transparency at Sila Heating, Cooling, Plumbing, and Electrical. I had an appointment on February 16, 2026, to troubleshoot a no-heat issue on the second floor of my home. I was told the repair would be $1,500. Although hesitant, I agreed to proceed because I needed heat. The repair was completed, I paid $1,524.90, and the technician left. I later realized I had not been provided with an invoice, so I called the company directly at 781 438 4114. The person who answered the phone emailed me an invoice. The invoice listed an HVAC diagnostic fee of $69.00, followed by ?HYD 170,? with no price or itemized breakdown provided. I understand that professional services and parts can incur significant costs, it is unreasonable that the part alone could account for the entire charge without any supporting documentation. I respectfully requested a detailed breakdown of the invoice through multiple phone calls and emails; however, the responses I received were dismissive and failed "

"The work was done correctly and promptly, but quite expensive. On the plus side, he presented all the options and didn't really try to upsell. Just the facts."

"Metro West Mini Splits recently installed 6 mini splits in February 2025 to our new home in Marlborough, MA. Alan, Jamie, and their team were so kind, respectful, knowledgeable, timely, communicative, and easy to work with. We could not be happier with the final product! Metro West Mini Splits was also very reasonably priced, and they made the Mass Save rebate process a breeze. 100% would recommend to anyone needing heating or cooling services!"

"Seamless. From the moment of making the appointment with the sales rep to come out to the follow-up phone call, I could not have asked for this installation to go better at a difficult time. They listened to my concerns regarding the look on the outside of the house and the location of units inside. They assisted with all aspects of the Mass Save program making the application process easy. They took care of actual submission of the paperwork where most companies wanted to provide the info to me to then submit."
