Midea MAP12S1TBL

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the Midea MAP12S1TBL.They may be the same unit sold under several brands, or different products that test the same: the DOE data has no dimensions or noise figures, so check those with the maker. Ratings within about 2% in capacity and 0.3 in CEER are treated as the same; a model whose own rating differs a little shows it in brackets.

Compared with every DOE-certified portable unit in the same size class (SACC). Each model number counts once. Yearly cost at 750 hours and 18.0¢/kWh.

This unit at each city's cooling hours and state electricity price, against a window unit that cools as much.

What size room does the Midea MAP12S1TBL cool?

10,000 BTU of real cooling (SACC) suits about 350 to 450 sq ft with normal sun and two people (about 315-405 sq ft if very sunny), by the ENERGY STAR floor-area table. Size by SACC, not the larger BTU on the box.

How many watts does the Midea MAP12S1TBL use, and what does it cost to run?

About 680 watts at full power (10,000 BTU/h divided by its CEER of 14.7), roughly 5.9 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $92, which is $79 less than the typical certified 10,000 BTU portable unit ($171). Its inverter compressor slows down once the room is cool, so real use is often lower. Its CEER beats 100% of the 706 certified models in its size class.

Why does the Midea MAP12S1TBL have two hoses?

One hose brings outdoor air in to cool the condenser, the other sends the heat out, so no cooled room air is wasted. 22% of the certified 10,000 BTU models have two hoses, and at 14.7 CEER this one is above their 7.9 median.

Do I have to empty the Midea MAP12S1TBL?

Usually not. It evaporates the water it removes and sends it out through the exhaust hose. In very humid weather the pan can still fill, and most units then stop and ask to be drained, so keep a drain hose or a bucket handy.

Can the Midea MAP12S1TBL also heat the room?

No, it only cools. 200 of the 706 certified 10,000 BTU portable models can also heat if you want one unit for the year.

Is the Midea MAP12S1TBL as efficient as a window air conditioner?

No. The 35 ENERGY STAR certified window units that cool about as much (within 15% of 10,000 BTU) have a median CEER of 15.0, against 14.7 here, and the best reach 17.6. At 750 hours a year a window unit with that median would cost about $90, $2 less than this one. ENERGY STAR window units are the more efficient part of the window market, so the gap to an average window unit is smaller. A portable unit makes sense when a window unit will not fit or is not allowed.

Which model numbers have the same ratings as the Midea MAP12S1TBL?

6 certified model numbers from 3 brands share these ratings: capacity, CEER, hose design, heating, drain type and compressor. They may be the same unit under different brands, or different products that test the same; the DOE data does not include dimensions or noise, so check those with the maker.
