Taking for granted you have the standard type AC. When standing under the AC if you look up at the plastic grill work the filters are behind that. There should be some sort of tab to releace the grill, once removed the filter will come with the grill remove filter wash dry and replace. However I doubt if the filters are the cause for the units not cooling. Sound like more involved than filters.
