Our verdict

A powerful window unit that cools and heats a large living room or den, with a remote, timer and auto restart. It needs a high-voltage circuit and weighs a lot, so plan electrical work and a helper for install.

Overview

Large living rooms, dens and finished basements are what this LG window unit covers, cooling hard in summer and adding supplemental heat on cool days. A remote, timer and four-way air deflection direct comfort, and auto restart resumes after power cuts.

One appliance for cooling and shoulder-season heat saves buying a separate heater for a big room. Coverage is broad. It runs on a dedicated high-voltage circuit and is very heavy, and the description and specs disagree on capacity and coverage.

Who it's for

Homeowners with big open rooms and the right circuit get year-round comfort from one unit. Apartments without high-voltage wiring cannot run it.

Pros and cons

Pros
  • Cools and heats in one unit
  • Covers large rooms
  • Auto restart after outages
  • Remote and timer control
Cons
  • Needs a high-voltage circuit
  • Very heavy to install
  • Capacity figures conflict in listing

Performance notes

Cooling power comes from the large compressor sized for big rooms, while the heat function provides supplemental warmth rather than whole-house heating. Two fan speeds and air deflection set how far air throws. The heavy chassis needs sturdy window support.
