    Product Description

    Summer’s great, but not if you’re stuck indoors without an air conditioner. Beat the heat this season with the Insignia NS-AC8WU3 350 Sq. Ft. 8,000 BTU U-Shaped Window Air Conditioner. A powerful BTU rating of 8,000 provides cool air for a room up to 350 sq. ft. Designed for vertical sliding windows, this air conditioner features an oscillating fan with 3 different speeds and both up/down and left/right adjustment options. A U-shaped construction reduces the amount of cool air that can escape while letting you keep your window closed or open. This air conditioner runs as low as 42 dBA – up to 9x quieter than most traditional units, while simultaneously using an inverter system and Energy Star certification to save you both money and energy. A handy air filter indicator and an auto restart mode both grant you the peace of mind in knowing this air conditioner has you covered no matter what. Finally, an included remote control lets you operate the unit from up to 26.2 ft. away. All this and more make this Insignia air conditioner an ideal way to stay cool and comfortable indoors.
