How many square feet does the Midea MAW08U1KWT cool?

At 7,800 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 MAW08U1KWT use?

About 517 watts at full power (7,800 BTU/h divided by its CEER of 15.1), which is 4.5 amps at 115 V. That is 16 W less than the typical unit in its class (533 W), or $2 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 MAW08U1KWT run on a standard outlet?

Yes. It runs on 115 V and draws about 4.5 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 MAW08U1KWT, 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 68% 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 19.2" width between the frame sides.

Is the Midea MAW08U1KWT 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 Midea MAW08U1KWT 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 MAW08U1KWT worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $117 a year to run at 750 hours and 18.0¢/kWh; this one costs about $70, so it saves roughly $47 a year.

Is the Midea MAW08U1KWT the same as the Midea MAW08U1KWT-A?

As far as the certified data goes, yes. ENERGY STAR lists 4 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.
