"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."

"Leominster, MA 01453 May 18, 2019 To Whom It May Concern: I am writing to highly recommend the excellent electric work of Matt Renzi based on my recent experience. My home required electric service updating and code compliance. Matt reconnected a closed-off outlet in the living room and established a new kitchen outlet which eliminated dangerous power-cord chaining. He also fixed the basement laundry room bringing the electric service into current code. Matt installed an outdoor, covered electric outlet and the property now has outdoor electric service. While he was working, he also noticed and disconnected a malfunctioning ceiling fan heater that would have resulted in property damage or worse. All his work was done quickly, and efficiently. Matt is committed and dependable. I would highly recommend his skills to anyone requiring electrical work. Janet S. Leominster, MA"
