Abstract: An air conditioner unit includes a variable speed compressor for circulating refrigerant through an outdoor heat exchanger and an indoor heat exchanger, an indoor fan, and an outdoor fan. A controller obtains an indoor temperature using an indoor temperature sensor and operates the variable speed compressor, the indoor fan, and the outdoor fan at a first capacity level to adjust the indoor temperature toward a target temperature. The controller determines that a rate of change of the indoor temperature is below a predetermined rate threshold and operates the variable speed compressor, the indoor fan, and the outdoor fan at a second capacity level.

Abstract: 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.

Abstract: Air conditioner units, bulkhead assemblies, and methods for operating air conditioner units are provided. A bulkhead assembly includes a bulkhead which includes a first sidewall, a second sidewall, and a rear wall extending laterally between the first sidewall and the second sidewall. The rear wall includes an indoor facing surface and an opposing outdoor facing surface. The bulkhead assembly further includes a vent aperture defined in the rear wall, and a vent door movable between an open position and a closed position, wherein in the open position the vent door permits air flow through the vent aperture and in the closed position the vent door inhibits air flow through the vent aperture. The bulkhead assembly further includes a drive assembly connected to the vent door and operable to selectively move the vent door between the open position and the closed position.
