Heating and/or cooling distribution that channels warm or cool air to different parts of a building. Equipment includes a blower or fan; heating and/or cooling coils; and related equipment such as controls, condensate drain pans, and air filters. It does not include ductwork, registers, grilles, boilers, or chillers. Conditioning may include particle filtering, adding or removing heat and moisture. A varying portion of the return air from the conditioned space may be recirculated and mixed with incoming air.

air-handling unit; packaged fan equipment

An assembly of air-conditioning components (such as fans, cooling coils, filters, humidifiers, and dampers) integrated into a self-contained package and often installed as a single unit, which is connected to system of metal ductwork that distributes the conditioned air.
