What size room does the LG LP0825WFR cool?

8,000 BTU of real cooling (SACC) suits about 250 to 350 sq ft with normal sun and two people (about 225-315 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 the LG LP0825WFR use, and what does it cost to run?

About 1096 watts at full power (8,000 BTU/h divided by its CEER of 7.3), roughly 9.5 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $148, which is $0 less than the typical certified 8,000 BTU portable unit ($148). Its CEER beats 42% 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.

How does the LG LP0825WFR handle the water it removes?

It collects the water in a removable bucket that you empty by hand when it fills.

Can the LG LP0825WFR 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 the LG LP0825WFR as efficient as a window air conditioner?

No. The 30 ENERGY STAR certified window units that cool about as much (within 15% of 8,000 BTU) have a median CEER of 15.0, against 7.3 here, and the best reach 17.0. At 750 hours a year a window unit with that median would cost about $72, $76 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.

8,000 BTU (SACC) single-hose portable air conditioner

LG LP0825WFR

Average efficiency for its size: a CEER of 7.3 beats 42% of the certified 8,000 BTU portable air conditioners.

The LG LP0825WFR delivers 8,000 BTU of real cooling (SACC), enough for about 250-350 sq ft, draws about 1096 watts and costs about $148 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $72 a year.

A good fit if…

You want a certified 8,000 BTU (SACC) single-hose portable air conditioner at a typical efficiency level.

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.
You want no drain to deal with - it uses a bucket you must empty.

These model numbers are certified with the same capacity, efficiency, hose design, heating, drain type and compressor as the LG LP0825WFR.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.
