I went with GSS due to the fact they were a local NH company and had better reviews than the national companies I was looking at. From start to finish GSS employee's were excellent. They answered all of my questions no matter how small. Their work crews were on time (or early), clean and professional. The entire process was as easy as it could be. My new system is working exceptionally well (last electric bill was $38) I would highly recommend them for your system.
