"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."

"Dodge installed a rooftop condenser and a coil above my hot air furnace. They coordinated the crane, installed everything in a day and left the workplace immaculate. This is a family run business. Good price. Highly ethical. This is the second major job they’ve done for me. Don’t look anywhere else!"

"Similar to the last review, Carlos did not complete the work we agreed upon. He was to upgrade an electrical panel and was supposed to pull a permit, but never did. He then realized after doing some of the work that it had to be moved further from a window to pass inspection. He asked for more of the payment up front than I was comfortable giving but he promised to do the work and said all he had to go on was his word, but as it turns out, his word is garbage. He then made excuse after excuse not showing up when he said he would then stopped returning calls. I will now be taking him to court. "
