How does my heating and air conditioning system move air throughout my home?

A fan draws indoor air in through vents called return grills located throughout your home. The air travels through ducts that run to your systems’ air handler, where it is returned into the conditioned space through supply vents or registers in your wall, ceilings or floors.
