Re: Cut hole in cement block load bearing wall for window A/C?



aside from a lintle, you should also consider the width of the wall, and how that will affect the air movement in the ac housing.
when they are window mounted, there are narrow window frames/sills for the ac to rest on, giving some space for air flow.
you may need to add similar structure for air flow.
