"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."

"I took a chance on hiring a young construction company to do some serious work around my house. Overall, their work ethic and professionalism just blew me away. Build Simple Inc.’s. Four-man team arrived every day and worked from 8:00 A.M. to about 6:30 P.M. every day. There work was impressive. In eight days they: • repaired rotting wood on garage • replaces seven existing windows and an entrance door • vinyl sided the garage • installed new gutters • demolished front porch and installed a new composite deck The workers were friendly and kept me informed as the project progressed. Everything came out amazing and I would recommend Build Simple in in a heartbeat."
