Good Idea Mike, thanks.
All I am worry about is this summer only - I meant for this year only, since I will install the Air-Conditioner for my whole house next year - The genterment estimated and quote for about 5-6k, so I figure it wont be really bad at all, since it also helped reduce dust and noice in summer by openning the windows like I 've been doing
But that's next year budget.
I think I'll use some fan blow to open top for this year, hope it will work for this year.
