How many square feet does the LG LW1522FVSM cool?

At 14,000 BTU/h it suits a room of about 450 to 700 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 495-770 sq ft; in a very sunny one it shrinks to 405-630 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the LG LW1522FVSM use?

About 952 watts at full power (14,000 BTU/h divided by its CEER of 14.7), which is 8.3 amps at 115 V. That is 15 W more than the typical unit in its class (938 W), or $2 a year dearer to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 27% of the 15 units in the class.

Can the LG LW1522FVSM run on a standard outlet?

Yes. It runs on 115 V and draws about 8.3 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. 13% of certified units in this class need 230 V, so a 115 V model is the easy case.

What are the dimensions of the LG LW1522FVSM, and will it fit my window?

23.6" W × 15" H × 28.8" D, 85 lb. It is narrower than 57% of its 14 competitors and lighter than 57% of them. It hangs over the sill, so check the sill depth and that the window can open far enough to set the unit in.

Is the LG LW1522FVSM saddle design an advantage?

For the view, yes: most of the body sits outside and below the sill, so it blocks less of the window than a box unit. At 85 lb, support it from outside until the bracket is fixed.

Can the LG LW1522FVSM also heat the room?

No, it only cools. If you also need heat, 0 certified units in this class can do both; see the list of air conditioners with heat.

Is the LG LW1522FVSM worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $210 a year to run at 750 hours and 18.0¢/kWh; this one costs about $129, so it saves roughly $82 a year.

Is the LG LW1522FVSM the same as the LG LW1522IVSM?

As far as the certified data goes, yes. ENERGY STAR lists both model numbers with the same capacity, efficiency, energy use, dimensions and weight, which means the same unit sold under another brand or with a different colour or retailer code. The full list is on this page.
