We live in a rental in Hawaii with A/C, but we still have high humidity (usually in the 60s but sometimes as high as 80% as after heavy rain). We recently bought a 35 pint dehumidifier for downstairs and we are emptying it twice a day, but it's keeping the levels down. Upstairs is still humid. We have small individual dehumidifers in each bedroom that don't seem to do anything. We keep the AC on 72-74 and set to auto. The HVAC and return air vent are upstairs and push out a lot of cold air to the top floor--at night it's usually 10 degrees cooler upstairs than whatever we set the thermostat to downstairs. I'm going to go ahead a buy another 35 pint (or maybe 50) for upstairs, but I have no idea where to put it to help all 3 bedrooms. The hallway is extremely narrow/maze like, and the dehumidifer sticks out really far. Where is the best placement based on this floor plan?
