12 kw system Our bills used to average about $600 a quarter. After installation of the system our bill came in at around $35. We were a little bit skeptical at first, but it’s been a good financial investment.
10 KW system I chose Costline after doing my research. The lady over the phone was very knowledgeable. The contractors are very efficient and did a great job. I am now in energy credit and it’s just been less than a month.
