This is the type that is built into the building, a central system and not a window mounted unit in each room. It's all great, but it alternates between ambient air (when the room is cold enough) and cooled air, when there is need for cooling.
If it wasn't for the dewpoint of the ambient air, which is often way above the temperature of the room, then it wasn't any problem. But as you pull the humid air into a cold room, it condensates and makes for an uncomfortable environment - sticky and moist is not really what you want!
