"This company cares,very professional. Between the consultation explaining the bulk of the job and the techs, they all knew what they were doing installing a propane furnace. Once techs were here they wore booties, put down tarps asked me a few questions and were off and running on the project. It was not an easy job (tight space). They had my house with heat with the new furnace by the end of the day. I highly recommend this company. You will not be disappointed. Thank you HomeAdvisor for finding them for me."

"Patrick came out and gave me a great estimate on replacing my 25 year old oil burner. He answered any and all questions I had and always got back to me if I needed any other information. He was prompt on the day of the installation and did a great job. I would definitely recommend him!"

"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."
