A furnace with a baffle assembly including at least one horizontal gap, and a heating, ventilation, and/or air conditioning (HVAC) system incorporating the same are provided. The furnace includes a furnace heat exchanger, a baffle assembly, and a fan. The baffle assembly is disposed adjacent to the furnace heat exchanger. The fan is in airflow communication with the furnace heat exchanger. The baffle assembly may include a first side and a second side. Each of the first side and the second side may respectively include a first section and a second section. A horizontal gap may be disposed between the first section and the second section (e.g., on either or both of the first side and the second side). The horizontal gap(s) may increase the efficiency of the furnace and/or the HVAC system.

Aspects of the invention are directed towards apparatus with cambered louvers. One or more embodiments of the invention describe a louver comprising a plurality of slats arranged in a vertical direction or a horizontal direction; and each of the slats in the louver comprise a leading edge, a trailing edge opposite to the leading edge, and a chord line connecting the leading edge with the trailing edge. Further, each of the slats in the louver has a cambered profile, wherein the cambered profile includes a camber distance varying in the range of about 20%-30% from the leading edge and a camber height varying in the range of about 5%-15% of a total camber height.

A grommet assembly includes a bolt assembly that has a head portion. A grommet includes a tapering bolt opening for accepting the bolt assembly. A projecting portion extends from a body portion and has an overhang adjacent a distal end. The bolt opening at least partially defines a radial gap between the grommet and the bolt assembly. The head portion of the bolt assembly is spaced from the distal end of the projecting portion by an axial gap.
