Air conditioner units and methods for operating air conditioner units are provided. A method includes determining a steady state speed of a blower fan of the air conditioner unit. The method further includes receiving a call for heating and activating the blower fan in response to the call for heating. The method further includes measuring a speed of the blower fan after activating the blower fan and comparing the measured speed of the blower fan to the steady state speed of the blower fan. When the measured speed of the blower fan is greater than the steady state speed of the blower fan, the method includes disabling one of a plurality of heater banks of a heating unit of the air conditioner unit.

A saddle window air conditioner includes an interior casing and an exterior casing. A chaseway extends between the interior casing and the exterior casing. A first sleeve of the chaseway is slidably received within a second sleeve of the chaseway such that a length of the chaseway between the interior casing and the exterior casing is adjustable by sliding the first sleeve within the second sleeve. A mounting bracket is mountable at a window. The mounting bracket includes a support leg, a lift foot slidably mounted to the support leg, and a spring coupled to the lift foot. The lift foot is connectable to the exterior casing. The spring urges the lift foot and the exterior casing upwardly on the support leg when the mounting bracket is positioned in the window and the lift foot is connected to the exterior casing.

An air conditioner unit and bracket for receiving a capacitor are provided. In one exemplary aspect, the air conditioner unit includes a bulkhead that defines an indoor portion and an outdoor portion of the unit. A wall of the bulkhead defines an opening that is accessible from the outdoor portion of the unit and is sized to allow a capacitor to be inserted therethrough. The bracket has a body that defines a mounting opening and has a grounding strap projecting from the body. The grounding strap projects vertically downward and inwardly toward a vertical centerline that extends through the center of the mounting opening. When the capacitor is received within the mounting opening, the grounding strap retains and electrically grounds the capacitor.

A compact fan and air conditioner assembly includes an air conditioner configured to be mounted in a stationary manner below a ceiling of a room. The air conditioner produces a quantity of cold air. A fan receives all of the quantity of cold air from the air conditioner. The fan has a housing configured to be mounted in a stationary manner below the air conditioner and blades configured to rotate about the housing. The fan blades have channels receiving the cold air from the air conditioner and the fan blades have slots formed therein for receiving the cold air from the channels and distributing the cold air into the environment as the fan blades rotate. A split fan and air conditioner assembly includes a floor stand on which the air conditioner and the fan are mounted.

An air conditioner unit and cover assembly therefore are provided. In one exemplary aspect, the air conditioner unit includes a bulkhead that defines an indoor portion and an outdoor portion of the unit. A wall of the bulkhead defines an opening that is accessible from the outdoor portion of the unit and is sized to allow various components to be accessed, serviced, and assembled through the opening. The unit includes a removable cover assembly that includes a cover and a gasket. The cover assembly and the wall of the bulkhead include various features for sealing the perimeter of the opening and for guiding one or more wires into the opening.

A fragrance delivery apparatus contains: a body, a fan, a power base, and a case.
