"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."

"Absolute ripoff, along with shady business practices. They were prompt and courteous, but that's about it. The technician came and had to replace a $200 part on my boiler, it took him under an hour to do the work. A simple Google search showed at least 10 places to buy the exact part, all around $200. No other parts were needed for this repair, I researched what is involved. I was charged almost $1000, including their $89 diagnostic fee just to walk in the door. So apparently it's a $600+/hour labor rate? I'm obviously in the wrong line of work. This was not an off hours emergency call either, it was a scheduled appointment in the middle of a weekday. The shadiest part of the entire thing was that on the invoice (that they email you later) they bury all the cost, it's not itemized i.e. labor vs parts cost. It just says replaced (part) = $1000. A super scummy and shady way to run a "professional" business, taking advantage of people who don't know any better. I wouldn't be surprised if they also sell used cars. Never again Gervais. You've all been warned."
