Disclosed is a grille assembly, which may comprise a grille plate including airflow cutouts within the grille plate, and may be designed to integrate with, or enhance the décor of a room. In certain embodiments, the grille assembly may further comprise an airflow regulator including a main body configured to insert into an airduct opening within a building structure, and the grille plate is configured to mount to a surface of the building structure over the airduct opening and airflow regulator inserted therein.

A vent register adapter is described which is designed specifically to assist in the installation of floor, ceiling and wall vent registers. All known vent registers are screwed directly into the vent surroundings. The surroundings are typically dry wall, wooden studs or the metal framework of the venting system itself. Often the vent void is somewhat irregular, which results in the vent register not fitting exactly or securely into the vent ducting. The embodiments of the invention relate to a rectangular plate having a layer of adhesive on the rear which can be attached around the vent void, thereby creating a regular and secure surface surrounding the vent ducting onto which the vent register can be attached.

Embodiments of the present disclosure are directed to collapsible hood for a heating and cooling system that includes a plurality of panels configured to couple to a housing of the heating and cooling system, wherein the plurality of panels is configured to be translated between a collapsed position and an open position, wherein the plurality of panels is substantially flush against the housing in the collapsed position to configure the heating and cooling system for transportation, and wherein the plurality of panels are configured to extend from the housing to protect openings in an air intake of the housing and to allow passage of air through the air intake in the open position.
