Air Conditioning Fan Home Air Conditioning - Fan Always On Or Auto?

Home air conditioning - fan always on or auto? - air conditioning fan

Typical House 2 floors, approx. 2500 square meters, the climate of the Midwest. Some say that the speed of change is running on "auto" because of the fans (On), where AC is not in the air, also continue to collect moisture from the windings' evaporator and wet and damp, because the house is too high. Others say, yes, will air "a little" weather, but leave the fan to "On" to keep the air in the house more evenly distributed between the upper and lower decks.

What should the fan settings - AUTO or ON?

Thx.
