The present invention is a heating and cooling airway vent (12) that provides improved airflow directional control and is easier to manufacture, assemble, and install in building airway systems. The airway vent (12) includes a housing (14) having a number of fixed louvers (16) as well as a plurality of rotatable circular openings (18) in which circular inserts (20) are rotatably mounted. The circular inserts include curved louvers (22) that are angled with respect to the vertical and that are curved slightly outward. The circular inserts (20) can be rotated to direct their louvers (22), and hence the issuing air, in any desired direction. The circular inserts (20) are snap-locked into the housings (14). The vent (12) includes one or more dampers (26) operated by a damper switch (28). The damper switch (28) is connected to the housing using a guide slot (46) having ridges (48) that aid a user in keeping the damper switch (28) in a particular position. The vent housing (14), the circular inserts (20), and dampers (26) are all injection molded of a suitably rigid plastic.
