They actually do both, as newer building codes now require a portion of the air circulated by the fan coil (aka: air handler, furnace) to be fresh outside air. Of course, if you are referring to an existing installation, it could very well predate the new code and do nothing of the sort, just simply recirculate the same old air over and over again. A competent inspection of your equipment will reveal exactly what you have and what options are available to you as well.

They circulate the air, and also dry it out. If you want an air condioner for the cooling aspect, consider a ducted evaporative system which will ultimatly provide clean, fresh air and will cost a tenth of the cost of a refridgerated unit to run.
