NETR was awesome. Chip did a great job explaining the products and process to me initially and Ryan S. killed it on the installation. He was on time, professional, and super efficient getting everything in and installed. He walked me through how to use the system and couldn't have been easier to work with.

I want to thank, beginning with Paul, and then the installation team of Ivan and Jawon for installing my new ductless heat/air conditioning system. They were courteous, prompt, responsive and professional. Oh yes, and patient with showing me how the system works after everything was cleaned up and ready to go.

Report
Jerry provided excellent service. He worked in the hottest weather of the summer, much of it in our attic, and never complained. He was completely professional at all times and showed that he was completely knowledgeable about the system he was installing. N.E.T.R. is fortunate to have people like Jerry working for them as he reflects the professionalism and integrity that I found with everyone in the company that I dealt with. I will recommend N.E.T.R. highly to any of my family and friends, some of whom have already fallen in love with our air conditioning.
