I have a quote from a company. Two of my neighbours had installation from this company. They said it did a good job. Another neighbour only paid about half the price from another company, but he wouldn't recomment it to me. They did a poor job. It was qouted around $1260 (2800 square ft) for my house one month ago. I am not sure if it is counted by house size. I'll call for the installation in this spring. If you are interested , I can give you the company name tomorrow, free estimation.
