LG Dual Inverter

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.

How we compare two lines

  • Only new units we can find in stock with a live price, at the same size. A line's average says more about its size mix than about the line.
  • A price difference counts when it is at least 5% and at least $20, and only between models that install the same way (a do-it-yourself kit is never priced against an installer-fitted system).
  • Efficiency is compared on one scale (CEER) and counts at a gap of 0.5 or more; noise counts at 3 dB(A) or more, using only ratings checked against the retailer's specification for the exact model.
  • Warranty terms are as each listing states them. Models named in a CPSC recall are never compared or sold here.

Friedrich Chill Premier vs LG Dual Inverter: common questions

Is Friedrich Chill Premier or LG Dual Inverter cheaper?
It depends on the size. Comparing each line's cheapest new, in-stock model at the same size, LG Dual Inverter's cheapest model costs less at 10,000 BTU ($397 against $489), 12,000 BTU ($428 against $579) and 18,000 BTU ($598 against $899) and Friedrich Chill Premier's at 8,000 BTU ($359 against $419). These are live retailer prices and change often.
Which is more energy efficient, Friedrich Chill Premier or LG Dual Inverter window air conditioners?
Comparing the best CEER rating each line publishes for its in-stock models at the same size, LG Dual Inverter has the higher-rated model at 8,000 BTU (CEER 15.5 against 15) and their best ratings are within 0.5 at 2 sizes. A higher CEER means less electricity for the same cooling. Not every listing publishes a rating, so a size with a rating on one side only is not compared.
What sizes do Friedrich Chill Premier and LG Dual Inverter window air conditioners come in?
In stock right now, Friedrich Chill Premier sells 5,000, 6,000, 8,000, 10,000, 12,000, 15,000, 18,000 and 24,000 BTU and LG Dual Inverter sells 8,000, 10,000, 12,000, 14,000 and 18,000 BTU. So only Friedrich Chill Premier sells 5,000, 6,000, 15,000 and 24,000 BTU and only LG Dual Inverter sells 14,000 BTU. Size the unit to the room first: an oversized unit short-cycles and leaves the air cool but damp.
Do Friedrich Chill Premier and LG Dual Inverter make inverter window air conditioners?
Friedrich Chill Premier has 3 inverter models in stock, and LG Dual Inverter has 5, going by each listing and the maker's model numbers. An inverter compressor slows down instead of switching on and off, which is usually quieter and more efficient at part load.
Which has the longer warranty, Friedrich Chill Premier or LG Dual Inverter?
As the retailer listings state it, in-stock Friedrich Chill Premier models cover the compressor for 5 years (13 of 15 listings state a term) and LG Dual Inverter models for 1 year (3 of 5). Where a listing names no separate compressor term, its general or parts term is what covers the compressor. Some terms require registering the unit, and a maker can require professional installation to honor its warranty, so read the warranty document before you buy.
Have any Friedrich Chill Premier or LG Dual Inverter window air conditioners been recalled?
None of the 21 Friedrich Chill Premier and 7 LG Dual Inverter window air conditioners we track is named in a CPSC recall notice we check. That covers the models listed here, not every model either line has sold, and it is not a safety certification.
