Properly engineered systems do not pull air from the interior of the home. They pull air from the soffits.
Regarding point # 2, I strongly disagree. Over the past ten years my company has replaced more than 1,500 roofs and installed hundreds of fans....without even one call back for a leak. Properly installed, it is virtually impossible for an attic fan to leak
3) There are ways to work around blocked soffits if you know what you are doing.
And you have to factor in the experience of the person that wrote the article. I new to this area so I know very little about the solar guys but I was a Solatube distributor for four years commencing in 2004. I have been to the Solatube manufacturing plant in California, and several other solar fan and sun tube manufacturing facilities. Like I said, I do not know the Solar Guys but I do know that I have more engineering and install experience than most salespeople do and I have engineered and installed a very large number of air and water management systems. I have not used sales people to sell my projects for the last seven years, because generally they don't have the same approach and convictions that an owner does.
