What size room does the LG LP0725WSSM cool?

7,400 BTU of real cooling (SACC) suits about 250 to 300 sq ft with normal sun and two people (about 225-270 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 LP0725WSSM use, and what does it cost to run?

About 1014 watts at full power (7,400 BTU/h divided by its CEER of 7.3), roughly 8.8 amps if it runs on 115 V. At 750 hours a year and 18.0¢/kWh that is about $137, which is $11 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.

Do I have to empty the LG LP0725WSSM?

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 LG LP0725WSSM 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 LP0725WSSM as efficient as a window air conditioner?

No. The 28 ENERGY STAR certified window units that cool about as much (within 15% of 7,400 BTU) have a median CEER of 15.0, against 7.3 here, and the best reach 16.0. At 750 hours a year a window unit with that median would cost about $67, $70 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 LG LP0725WSSM?

6 certified model numbers from 4 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.

7,400 BTU (SACC) single-hose portable air conditioner

LG LP0725WSSM

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

The LG LP0725WSSM delivers 7,400 BTU of real cooling (SACC), enough for about 250-300 sq ft, draws about 1014 watts and costs about $137 a year to run at typical U.S. use and prices. A window unit that cools as much costs about $67 a year.

CEER: 7.3 Combined efficiency, higher is better
Average · beats 42%
Real cooling: 7,400 BTU/h (SACC)For about 250-300 sq ft
Energy use: 760 kWh/yrAbout 1014 W, at 750 hours a year
Design: One hose Uses room air for its condenser

A good fit if…

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.
