How many square feet does the LG LW8022IVSM cool?

At 8,000 BTU/h it suits a room of about 250 to 350 sq ft with normal sun and two people, following the ENERGY STAR sizing guide. In a heavily shaded room that stretches to about 275-385 sq ft; in a very sunny one it shrinks to 225-315 sq ft. A kitchen needs 4,000 BTU more.

How many watts and amps does the LG LW8022IVSM use?

About 516 watts at full power (8,000 BTU/h divided by its CEER of 15.5), which is 4.5 amps at 115 V. That is 17 W less than the typical unit in its class (533 W), or $2 a year cheaper to run at 18.0¢/kWh. Its inverter compressor slows down instead of cycling, so real use is usually lower. Its CEER beats 62% of the 29 units in the class.

Can the LG LW8022IVSM run on a standard outlet?

Yes. It runs on 115 V and draws about 4.5 A, well inside a standard 15 A outlet, but do not share the circuit with a space heater, microwave or other big load. Every certified unit in this class is 115 V.

What are the dimensions of the LG LW8022IVSM, and will it fit my window?

19.6" W × 12.4" H × 24.5" D, 63 lb. It is narrower than 39% of its 28 competitors and lighter than 11% 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 LW8022IVSM 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 63 lb, support it from outside until the bracket is fixed.

Can the LG LW8022IVSM also heat the room?

No, it only cools. If you also need heat, 4 certified units in this class can do both; see the list of air conditioners with heat.

Is the LG LW8022IVSM worth buying to replace an old air conditioner?

An old unit of the same size at 9 CEER would cost about $120 a year to run at 750 hours and 18.0¢/kWh; this one costs about $70, so it saves roughly $50 a year.
