What size room does a unit with these ratings cool?

6,250 BTU of real cooling (SACC) suits about 150 to 250 sq ft with normal sun and two people (about 135-225 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 868 watts at full power (6,250 BTU/h divided by its CEER of 7.2), roughly 7.5 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $117, which is $6 less than the typical certified 6,000 BTU portable unit ($123). Its CEER beats 81% of the 458 certified models in its size class.

Is a one-hose portable air conditioner a problem?

It is the common design: 100% of the certified 6,000 BTU models have one hose, with a median of 6.6 CEER. The top-ranked 6,450 BTU single-hose portable AC, 7.4 CEER reaches 7.4 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. 18 of the 458 certified 6,000 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 9 ENERGY STAR certified window units that cool about as much (within 15% of 6,250 BTU) have a median CEER of 15.1, against 7.2 here, and the best reach 16.0. At 750 hours a year a window unit with that median would cost about $56, $61 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?

105 certified model numbers from 35 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.

6,250 BTU (SACC) single-hose portable air conditioner

6,250 BTU single-hose portable AC, 7.2 CEER

Very good efficiency for its size: a CEER of 7.2 beats 81% of the certified 6,000 BTU portable air conditioners.

A unit with these ratings delivers 6,250 BTU of real cooling (SACC), enough for about 150-250 sq ft, draws about 868 watts and costs about $117 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $56 a year.

Includes EUHOMY PAC002-10K, simzlife PAC002-10K, Temprium PAC002-10K and 102 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 81% of the 458 certified 6,000 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.
