What size room does a unit with these ratings 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 a unit with these ratings use, and what does it cost to run?

About 1266 watts at full power (10,000 BTU/h divided by its CEER of 7.9), roughly 11.0 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $171, which is $0 less than the typical certified 10,000 BTU portable unit ($171). Its CEER beats 34% of the 706 certified models in its size class.

Is a one-hose portable air conditioner a problem?

It is the common design: 78% of the certified 10,000 BTU models have one hose, with a median of 7.9 CEER. The top-ranked Midea MAP12S1TBL has two hoses and 14.7 CEER.

Do I have to empty a unit with these ratings?

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.

How does a unit with these ratings heat?

It has a heating function, but the DOE data records only that it exists, not whether it is a heat pump or an electric element. Ask the maker: a heat pump gives more heat per kWh than a resistance element, which costs the same as any space heater. 200 of the 706 certified 10,000 BTU models can heat.

Is a unit with these ratings 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 7.9 here, and the best reach 17.6. At 750 hours a year a window unit with that median would cost about $90, $81 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 a unit with these ratings?

159 certified model numbers from 38 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. The full list is on this page.

10,000 BTU (SACC) single-hose portable air conditioner with heat

10,000 BTU single-hose portable AC with heat, 7.9 CEER

Below average efficiency for its size: a CEER of 7.9 beats 34% of the certified 10,000 BTU portable air conditioners.

A unit with these ratings delivers 10,000 BTU of real cooling (SACC), enough for about 350-450 sq ft, draws about 1266 watts and costs about $171 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $90 a year.

Includes Midea MAP10HS1WBL, Whynter ARC-148MHP, Frigidaire FHPH142AA1 and 156 more model numbers, all certified at these ratings. Full list

A good fit if…

You want one unit for cooling and some heat - it has a heating mode.
You do not want to empty a bucket - it evaporates the water and sends it out through the hose in normal weather.

Think twice if…

Running cost matters most - its CEER is below average for 10,000 BTU portable air conditioners.
You want the most efficient design - one-hose units pull warm air in through gaps; dual-hose units lead the efficiency ranks.

Power draw is capacity divided by CEER, which already includes standby power. Inverter units often run below full power, so real use can be lower. Electricity prices: U.S. EIA residential averages (12 months to July 2026). Days a year start from your state's cooling degree days (NOAA 1991-2020 normals).
