Totally dissatisfied with the company and their service. Took almost a full year to get my system up and running--I was paying interest on the system for months before it was even functional. Finally it starts working in February 2017. The amount of energy savings I'm getting is less than $10/month. I was sold a system that was supposed to save an average of $130/month. They keep saying "give it a year." Doesn't make sense--how are 6 months of average $10/month savings going to ever average to $130/month? I think the system is defective, but the company refuses to send out a technician to even look at it. Unbelievably frustrating, and I'm losing thousands of dollars compared to what I was promised. Do NOT trust this company.
