Prices are live retailer offers and change often; compare.ac may earn a commission on purchases, at no cost to you. Where one model number is sold as more than one listing, the row shows the cheapest and links the others. Portable units are often advertised by their older ASHRAE rating; the DOE's SACC rating, which counts the heat that leaks back in, is lower, so a portable's BTU does not compare directly with a window unit's.
LG builds its Dual Inverter room units around a variable-speed compressor that changes speed to hold the temperature instead of cycling on and off. The 23,500 BTU LW2422IVSM needs a 208/230 V circuit, and the LP1419IVSM in the line is a portable that LG rates at 10,000 BTU by the DOE (SACC) method and 14,000 BTU by the older ASHRAE method.

Right now the in-stock LG Dual Inverter models we track range from $397 (the 10,000 BTU LW1022IVSM at Abt Electronics) to $698 (the 23,500 BTU LW2422IVSM at Abt Electronics). Prices are live retailer offers and change often.
Among the 6 LG Dual Inverter models rated on the CEER scale, the 8,000 BTU LW8022IVSM rates highest at CEER 15.5. A higher CEER means less electricity for the same cooling.
