Does this sound like it will take care of the problem we have with the ac not cooling? Advice please????? I hate to cut another hole if this won't work!
I think that will work, but heat rises, so you may end up pulling heated air back into the intake where you want cooler air to come in, not warmer air. Best to get the cool air, from below or far away from the hot air vent. A little will probably make no noticeable difference, but if a sizable percentage of the hot air gets pulled back in, efficiency and cooling effectiveness will be affected to some degree.
