Daniel was the sales rep. Does not work on commission and therefore no push for things I did not need. Work experience from from ground, up and very knowledgeable and patient. Did my due diligence and he was happy to discuss and give an unbiased opinion. I was able to reach him by phone (several times) and he was responsive (after his initial visit). Spending this type of money for me, requires a LOT of questions/answers. Installers did their jobs as professionals and lived up to what was on paper.
