I was very surprised just how quiet this thing is when in cooling mode! And as for running the heat pump or dehumidifier you have a built in lower condensate output pump (hose included) which means the hose can go upwards, out from a window if need be. As for this model having a dual hose (exhaust and intake) feature you can't go wrong, as it won't suck in air through your door or window seams defeating the temperature control in your home as a single hose unit would present. Yes I'm a happy camper!
