wall vented attic fans

  1. 2nd Floor Ventilation in OLD 2 story House

    HVAC
    The 2nd floor -- containing our 3 bedrooms -- IS my attic in my circa 1824 Bayman's Cottage. During the day the first floor is cooled by 1 window AC that does a decent job... but the 2nd floor heats up unbearably to over 100 degrees. If I do a whole house fan, I'm afraid it will suck unhealthy...
