"Buck and Wayne installed a mini split heating and cooling system in an attic bedroom/bath. The space was very tight and it took a lot of expertise and creativity on their part to hide all the piping. The outside unit mounted on the back of the house above a porch is a lot more visible than I thought it would be but they did everything they could to make it less intrusive. They arrived before 8 am and had to work outside in some bitter temperatures to install the outdoor unit. At the end of the day, Buck and Wayne took time to made sure that I knew how to operate the unit and that I could call if I had questions. I did a walk-through after they left and the rooms including the attic storage space were spotless. I would highly recommend them for any heating and cooling work you are considering."

"From start to finish, NETR did a fantastic job. I met 3-4 other vendors, and they didn't come close to NETR's responsiveness, professionalism, or timeliness. NETR earned my business before I even got a quote from some of the others. The salesman, Mark, arrived on time, was respectful & attentive to what we needed, explained our options well, and provided a competitive quote before he left my home. NETR also offered a 5-year 0% interest loan for the project (via a relationship with GreenSky). It took only a few days to schedule installation. The installers were prompt, professional, respectful of our property, and did an excellent job installing the electrical components, compressor, branch box, and 5 heads. They did a nice job of consolidating and hiding the lines on the outside of the house. This past year, we've worked with many contractors, some good, some terrible, so I can compare. NETR was one of the best, and I would hire them for my next project in a heartbeat."
