      A good fit if…

      • You want heat in spring and fall - it runs as a heat pump in reverse.
      • You want to plug it into an ordinary outlet - it runs on 115 V.
      • You want the very top tier - it meets the ENERGY STAR Most Efficient criteria.

      Think twice if…

      • Running cost matters most - its CEER is below average for 8,000 BTU window air conditioners.

      Questions6
      How many square feet does the Midea MAW08HV1CWT cool?
      At 8,000 BTU/h it suits a room of about 250 to 350 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 275-385 sq ft; in a very sunny one it shrinks to 225-315 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the Midea MAW08HV1CWT use?
      About 552 watts at full power (8,000 BTU/h divided by its CEER of 14.5), which is 4.8 amps at 115 V. That is 19 W more than the typical unit in its class (533 W), or $2 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 7% of the 29 units in the class.
      Can the Midea MAW08HV1CWT run on a standard outlet?
      Yes. It runs on 115 V and draws about 4.8 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 Midea MAW08HV1CWT, and will it fit my window?
      19.4" W × 13.9" H × 22.2" D, 56 lb. It is narrower than 43% of its 28 competitors and lighter than 43% of them. The window must be wider than 19.4"; the side panels fill the remaining gap.
      How does the Midea MAW08HV1CWT heat?
      It reverses its refrigerant cycle to work as a heat pump, which makes it one of only 4 certified units in its class that heat. Heating output is not part of the ENERGY STAR data, so ask the maker for its heating capacity and lowest outdoor temperature before relying on it in winter.
      Is the Midea MAW08HV1CWT worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $120 a year to run at 750 hours and 18.0¢/kWh; this one costs about $75, so it saves roughly $46 a year.

      Electricity used: 728 kWh a yearAn old 9 CEER unit of the same size would cost $188

      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).
