      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.

        Questions7
        How many square feet does the Midea MAW08HV1KWT-A 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 MAW08HV1KWT-A use?
        About 530 watts at full power (8,000 BTU/h divided by its CEER of 15.1), which is 4.6 amps at 115 V. That is 3 W less than the typical unit in its class (533 W), or $0 a year cheaper to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 52% of the 29 units in the class.
        Can the Midea MAW08HV1KWT-A run on a standard outlet?
        Yes. It runs on 115 V and draws about 4.6 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 MAW08HV1KWT-A, 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 MAW08HV1KWT-A 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 MAW08HV1KWT-A 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 $72, so it saves roughly $49 a year.
        Is the Midea MAW08HV1KWT-A the same as the Midea MWAUQB-08HRFN8-BCN11?
        As far as the certified data goes, yes. ENERGY STAR lists both model numbers with the same capacity, efficiency, energy use, dimensions and weight, which means the same unit sold under another brand or with a different colour or retailer code. The full list is on this page.

        Electricity used: 699 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).
