 If it's really, really damp like that, it's going to start to make the air conditioning feel cold and clammy. And secondly, the air itself, it can be contaminated. You can have radon. You can have dust. You can have mildew or mold spores in that air. So generally, we don't use the basement air as a source for air. Pretty much let the HVAC system do that. If the basement is finished, then you could have a return duct down there that pulls air from the basement into the HVAC system, but it wouldn't be a supplemental system by itself.
