LG LP1419IVSM: What to Know
The LP1419IVSM is rated at 14,000 BTU under the ASHRAE standard and 10,000 BTU SACC/DOE, which is a wider gap between the two figures than the roughly 14,000/12,000 split on the Midea and Whynter units above, a reminder that the ASHRAE-to-SACC ratio isn't fixed across brands, and the bigger number on the box tells you less than it appears to. LG claims coverage up to 500 sq ft and markets the compressor under its "Dual Inverter" branding, LG's term for the variable-speed technology it also uses in its window and split-system air conditioners; a mechanical difference from the single variable-speed compressors used by the other inverter units in this guide beyond LG's own marketing language was not independently verified.
Unlike the originally drafted LP1025WHSM, which LG's own site lists with a supplemental heater, this LP1419IVSM is cooling-only, running Cool, Fan, and Dry modes with no heat function. That's a real functional difference from the draft candidate, not just a model-number swap, so anyone specifically shopping for a heat-capable LG portable AC should look at LG's WHSM-series instead and buy directly from LG or a retailer that carries it, since it isn't confirmed on Amazon.
Control runs through LG's ThinQ app in addition to Amazon Alexa and Google Assistant, and LG's own materials brand its sound profile "Lo-Decibel" without a specific dB figure on the pages reviewed; RTINGS has published a full independent test report on this exact model for buyers who want a verified noise and cooling number rather than marketing language.
