Does this room need a de-humidifier?

Question

For some reason when i go to my grandmothers house, yes the air conditioning works, but it always feels "damp" and "humid". I mean, when i go anywhere else, especially my house, it always feels cool, comfortible and crisp. Is it just because of the air in the house, or does it need something more? i know they make dehumidifiers, but im not sure if this is what it needs. We used to have one in our old house, but we always kept it in the basement to run. She has central airconditioning by the way, if that helps. thank you!

Answer 1

Only if the humidity level is over 50%.
