Yeah it doesn't seem to matter if it runs for 6 hrs straight (which it does when temps get around 100*) the humidity is still excessive. Home was built in 2010 and is 1500sq/ft and noticed insulation is blown right on top of sheetrock in attic with no vapor barrier. Not sure if vapor barriers are only a yankee thing, but you'd think it would help cut down on humidity along with plastic under slab.Sometimes if you go too big for the space, the unit doesn't run long enough to drop the humidity to an appropriate level. Might research your specifics to determine what is best.
