LG LP1419IVSM review

LG's LP1419IVSM is the portable to consider if you already use LG appliances. LG lists 10,000 BTU on the SACC scale and 14,000 BTU on ASHRAE, with coverage for rooms up to 450 sq ft, and uses a dual inverter compressor that LG says uses less energy than non-inverter models. The LG ThinQ app lets you adjust settings, set schedules and monitor energy use, and the unit works with Alexa and Google Assistant. An auto swing vent spreads air across the room, and LG's auto evaporation system minimizes draining. Other listed features are multiple fan speeds, a 24-hour timer and auto restart after a power cut, plus a window kit LG describes as easy to install. LG calls it one of the quietest portable ACs available but does not publish a decibel figure on the page, which makes direct comparison with Midea's 42 dBA or Dreo's 42 dBA harder. LG's US store lists it at $699.00.
