      Best U-shaped window air conditioners

      A U-shaped unit straddles the window: the sash closes down into a slot in the middle, with the compressor outside and the fan inside. The window seals better, more light gets in, and the noisy part stays outside the glass.

      Before you buy

      Tips2
      • Check the window: U-shaped units fit single- and double-hung windows that slide up, not sliders or casements.
      • Makers list a minimum and maximum window opening height and a sill depth; measure before ordering.
      Questions3
      What is the best u-shaped window air conditioners?
      On certified efficiency, the Gradient CCHP11: 9,300 BTU at a CEER of 16.8, about $75 a year at typical U.S. use. If small matters more, the Midea 1010451315 is the pick. Every ENERGY STAR certified window unit that straddles the window, ranked by CEER.
      How much does it cost to run?
      A typical unit on this list (8,000 BTU, 15.0 CEER) draws about 533 watts and costs about $72 a year at 750 hours and the U.S. average electricity price. The calculator works it out for your state.
      What is the quietest window air conditioner?
      ENERGY STAR does not test noise, so no certified list can name the quietest unit. What helps: a U-shaped or saddle design puts the compressor outside the glass, and a variable-speed compressor avoids loud on and off cycles. All 55 units in this list have both. Compare the decibel rating on the maker's spec sheet, measured at the lowest fan speed.
