Hotel converted into apartments, no return inside building for 2 5 ton units feed 4 floors of common space halls. Exclusively pulling in fresh air. It was 92% relative humidity all week... Checked under return cover plate. Concrete. Any recommendations to run a return? Not familiar with these block construction buildings. Or any recommendations for commercial HVAC contractors in South Carolina?
