"Was great. Roof was replaced in one day and panels were installed a few days later and it only took several hours. The roof crew and panel crew were both professional and respectful. Garfield was a great person to deal with when we decided to go Solar. He let us know when things would take place and always accommodated us as well. We are excited to get them going. Oh, and they look great too."

"They did an excellent job. Instead of replacing an entire panel which would have been more costly and more labor intensive, the took the time to research the issue with the furnace manufacturer and were able to fix it quickly and much more economically. They were professional to deal with and prompt in their service.
They also did a middle of the night call for me sometime in December for a water heater that went bad and were efficient, prompt and very easy to work with. Within two hours I had a new water heater installed and was back in business.
