How many square feet does the Midea MAH09B1AGR cool?

At 9,500 BTU/h it suits a room of about 350 to 400 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 385-440 sq ft; in a very sunny one it shrinks to 315-360 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the Midea MAH09B1AGR use?

About 540 watts at full power (9,500 BTU/h divided by its CEER of 17.6), which is 4.7 amps at 115 V. That is 127 W less than the typical unit in its class (667 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 96% of the 28 units in the class.

Can the Midea MAH09B1AGR run on a standard outlet?

Yes. It runs on 115 V and draws about 4.7 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 MAH09B1AGR, and will it fit my window?

25" W × 20.9" H × 41.2" D, 129 lb. It is narrower than 22% of its 27 competitors and lighter than 4% of them. It hangs over the sill, so check the sill depth and that the window can open far enough to set the unit in.

Is the Midea MAH09B1AGR saddle design an advantage?

For the view, yes: most of the body sits outside and below the sill, so it blocks less of the window than a box unit. At 129 lb, support it from outside until the bracket is fixed.

How does the Midea MAH09B1AGR heat?

It reverses its refrigerant cycle to work as a heat pump, which makes it one of only 6 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 MAH09B1AGR worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $143 a year to run at 750 hours and 18.0¢/kWh; this one costs about $73, so it saves roughly $70 a year.

Is the Midea MAH09B1AGR the same as the Midea MAH09H1AGR?

As far as the certified data goes, yes. ENERGY STAR lists 7 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.
