It's difficult to find reliable contractors these days. I was pleasantly surprised to finally get a good one. I used Josh for my Generac generator install and Solar. I've also had him back to wash my solar panels. I increased my solar output by 20%. Money well spent.

I was in a bind when my Honda 2200 generator quit working. I was leaving to go out of town for the week but would need to use the generator when I returned. They had me drop it off with them before I left and had it all fixed up by the time I got back home and needed to use it. They were great :)
