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.

A drainage tray may be provided for collecting condensate from a heat pump that is adapted to be mounted on a support. The support may be mountable to at least one supporting structure to carry the weight of the heat pump and the support. The drainage tray may include a peripheral edge portion defining a central recessed portion configured to collect condensate. A condensate outlet may be provided for removing the condensate from the tray. The drainage tray may be configured to be arranged between an underside of the heat pump and the support. The drainage tray may have a trapezoidal shape.

A packaged terminal air conditioner unit (PTAC) includes a bulkhead that defines an indoor portion and an outdoor portion. An outdoor fan is positioned within the outdoor portion and a controller is communicatively coupled with the outdoor fan for receiving a command to generate white noise and operating the outdoor fan to create the white noise at a desired decibel level to block out ambient sounds. A user may regulate the outdoor fan speed when the PTAC is not heating or cooling by setting a desired decibel level, e.g., using a control panel of the PTAC.

A blower mounting assembly of a heating, ventilation, and/or air conditioning (HVAC) system includes a bracket assembly including a base panel, a plurality of mounting flanges extending from the base panel, and an alignment flange extending from and transverse to the base panel. The blower mounting assembly includes a first mounting aperture extending through the base panel in a first direction and includes second mounting apertures extending through the plurality of mounting flanges in a second direction transverse to the first direction. The blower mounting assembly includes a bolt configured to extend through and slidably engage with an aperture of the alignment flange and a blower mounting skid such that the bolt limits movement of the blower mounting skid relative to the bracket assembly. The aperture of the alignment flange extends through the alignment flange in a third direction transverse to the first mounting aperture and the second mounting apertures.

An air-sending device includes a fan and a grille provided downstream of the fan in a direction of airflow generated by the fan. The grille includes a first grille that includes a plurality of first bars spaced from each other, and a second grille that includes a plurality of second bars spaced from each other. The plurality of second bars are more densely arranged than the plurality of first bars. The second grille is provided upstream of the first grille in the direction of the airflow generated by the fan, and spaced from the first grille to face the first grille.
