What size room does a unit with these ratings cool?

8,300 BTU of real cooling (SACC) suits about 300 to 350 sq ft with normal sun and two people (about 270-315 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 776 watts at full power (8,300 BTU/h divided by its CEER of 10.7), roughly 6.7 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $105, which is $43 less than the typical certified 8,000 BTU portable unit ($148). Its CEER beats 89% of the 710 certified models in its size class.

Is a one-hose portable air conditioner a problem?

It is the common design: 92% of the certified 8,000 BTU models have one hose, with a median of 7.3 CEER. The top-ranked Hisense HIAP0825TWD has two hoses and 13.5 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.

Can a unit with these ratings also heat the room?

No, it only cools. 146 of the 710 certified 8,000 BTU portable models can also heat if you want one unit for the year.

Is a unit with these ratings as efficient as a window air conditioner?

No. The 34 ENERGY STAR certified window units that cool about as much (within 15% of 8,300 BTU) have a median CEER of 15.1, against 10.7 here, and the best reach 17.6. At 750 hours a year a window unit with that median would cost about $74, $31 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?

49 certified model numbers from 17 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.

8,300 BTU (SACC) single-hose portable air conditioner

8,300 BTU single-hose portable AC, 10.7 CEER

Very good efficiency for its size: a CEER of 10.7 beats 89% of the certified 8,000 BTU portable air conditioners.

A unit with these ratings delivers 8,300 BTU of real cooling (SACC), enough for about 300-350 sq ft, draws about 776 watts and costs about $105 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $74 a year.

Includes Antarctic Star A011E-8K, Auseo A011E-8K, COWSAR A011E-8K and 46 more model numbers, all certified at these ratings. Full list

Design: One hose Uses room air for its condenser

A good fit if…

You want low bills - its CEER beats 89% of the 710 certified 8,000 BTU portable models.
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…

You want the most efficient design - one-hose units pull warm air in through gaps; dual-hose units lead the efficiency ranks.
You also need heat - it cools only.

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.
