      A good fit if…

      • You want a quieter room and a usable window - the window closes into the U, so the compressor sits outside the glass.
      • You want to plug it into an ordinary outlet - it runs on 115 V.
      • You install it yourself - at 33 lb one person can lift it into a window.

      Think twice if…

      • Running cost matters most - its CEER is below average for 5,000-6,000 BTU window air conditioners.
      • You also need heat - it cools only.

      Questions7
      How many square feet does the Whirlpool WHAW061CX cool?
      At 6,000 BTU/h it suits a room of about 150 to 250 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 165-275 sq ft; in a very sunny one it shrinks to 135-225 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the Whirlpool WHAW061CX use?
      About 438 watts at full power (6,000 BTU/h divided by its CEER of 13.7), which is 3.8 amps at 115 V. That is 41 W more than the typical unit in its class (397 W), or $5 a year dearer to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 8% of the 12 units in the class.
      Can the Whirlpool WHAW061CX run on a standard outlet?
      Yes. It runs on 115 V and draws about 3.8 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. Every certified unit in this class is 115 V.
      What are the dimensions of the Whirlpool WHAW061CX, and will it fit my window?
      16" W × 12" H × 13.1" D, 33 lb. It is narrower than 55% of its 11 competitors and lighter than 73% of them. The window closes into the U-shaped slot, so measure the opening height as well as the width: you need at least the unit's 16" width between the frame sides.
      Is the Whirlpool WHAW061CX U-shaped design an advantage?
      Mostly yes. The sash closes into the unit, so the window stays sealed and daylight comes in, and the compressor is outside the glass, which cuts noise indoors. The trade-off is a window that must slide up and down, and a few extra steps to fit the foam seals.
      Can the Whirlpool WHAW061CX also heat the room?
      No, it only cools. If you also need heat, 0 certified units in this class can do both; see the list of air conditioners with heat.
      Is the Whirlpool WHAW061CX worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $90 a year to run at 750 hours and 18.0¢/kWh; this one costs about $59, so it saves roughly $31 a year.

      Power draw is capacity divided by CEER, which already includes standby power. Inverter units often run below full power, so real use can be lower. Electricity prices: U.S. EIA residential averages (12 months to July 2026). Days a year start from your state's cooling degree days (NOAA 1991-2020 normals).
