Met company reps at a Home Show in Daytona Beach. I had seen an ad for the product in the Daytona Beach News-Journal and was able to actually see and receive more information on it at the show. I decided to have it installed on my home. There were 3 other vendors at the Home Show with a similar product. This product by far looked like the best of the three. The price was reasonable and there was a 30% energy tax deduction which also made it attractive. My installer was very knowledgeable and was able to answer all my concerns.
