How many square feet does the Midea MAW18RV1KWT cool?

At 18,000 BTU/h it suits a room of about 700 to 1000 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 770-1100 sq ft; in a very sunny one it shrinks to 630-900 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the Midea MAW18RV1KWT use?

About 1125 watts at full power (18,000 BTU/h divided by its CEER of 16.0), which is 4.9 amps at 230 V. That is 125 W less than the typical unit in its class (1250 W), or $17 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 80% of the 10 units in the class.

What outlet does the Midea MAW18RV1KWT need?

It is a 230 V unit that draws 4.9 A, so it needs its own 230 V circuit with a matching plug (typically NEMA 6-15 or 6-20). If the room has only ordinary 115 V outlets, an electrician has to add one. Only 100% of the 10 certified units in this class are 230 V.

What are the dimensions of the Midea MAW18RV1KWT, and will it fit my window?

25.4" W × 17.9" H × 23.6" D, 94 lb. It is narrower than 56% of its 9 competitors and lighter than 89% of them. The window must be wider than 25.4"; the side panels fill the remaining gap.

Can the Midea MAW18RV1KWT 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 MAW18RV1KWT worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $271 a year to run at 750 hours and 18.0¢/kWh; this one costs about $152, so it saves roughly $118 a year.

Is the Midea MAW18RV1KWT the same as the Midea MAW18S2KWT-A?
