      Questions7
      How many square feet does the Midea 1014634880 cool?
      At 14,000 BTU/h it suits a room of about 450 to 700 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 495-770 sq ft; in a very sunny one it shrinks to 405-630 sq ft. A kitchen needs 4,000 BTU more.
      How many watts and amps does the Midea 1014634880 use?
      About 933 watts at full power (14,000 BTU/h divided by its CEER of 15.0), which is 8.1 amps at 115 V. That is 4 W less than the typical unit in its class (938 W), or $1 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 47% of the 15 units in the class.
      Can the Midea 1014634880 run on a standard outlet?
      Yes. It runs on 115 V and draws about 8.1 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. 13% of certified units in this class need 230 V, so a 115 V model is the easy case.
      What are the dimensions of the Midea 1014634880, and will it fit my window?
      21.7" W × 14.7" H × 19" D, 56 lb. It is narrower than 64% of its 14 competitors and lighter than 93% of them. The window must be wider than 21.7"; the side panels fill the remaining gap.
      Can the Midea 1014634880 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 Midea 1014634880 worth buying to replace an old air conditioner?
      An old unit of the same size at 9 CEER would cost about $210 a year to run at 750 hours and 18.0¢/kWh; this one costs about $126, so it saves roughly $84 a year.
      Is the Midea 1014634880 the same as the Midea MAW14R1VWT?
      As far as the certified data goes, yes. ENERGY STAR lists 13 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: 1,232 kWh a yearAn old 9 CEER unit of the same size would cost $329

      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).
