The window fans are working fine, the issue is that I needed a window panel extenders.  They came with the one, but my windows are a bit wider.  I went to the Holmes website and ordered the panels and they were too short.  Apparently, its a common issue for years.  They need to update their website.  I am calling customer service directly, been on hold so far 15:30. After seeing reviews on the reviews on their site and here, the bad reviews on customer service holds true.
