How many square feet does the Midea MWEUWA-08CRFN8-BCP0 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 MWEUWA-08CRFN8-BCP0 use?

About 500 watts at full power (8,000 BTU/h divided by its CEER of 16.0), which is 4.3 amps at 115 V. That is 33 W less than the typical unit in its class (533 W), or $5 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 69% of the 29 units in the class.

Can the Midea MWEUWA-08CRFN8-BCP0 run on a standard outlet?

Yes. It runs on 115 V and draws about 4.3 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 MWEUWA-08CRFN8-BCP0, and will it fit my window?

19.2" W × 13.5" H × 22" D, 53 lb. It is narrower than 57% of its 28 competitors and lighter than 57% of them. The window must be wider than 19.2"; the side panels fill the remaining gap.

Can the Midea MWEUWA-08CRFN8-BCP0 also heat the room?

No, it only cools. If you also need heat, 4 certified units in this class can do both; see the list of air conditioners with heat.

Is the Midea MWEUWA-08CRFN8-BCP0 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 $68, so it saves roughly $53 a year.
