Overview

The LG LW1216HR is a 12,000 BTU window air conditioner built for rooms up to 550 square feet. It stands out from standard window units by including a supplemental heating mode, giving it usefulness beyond the summer months. Two cooling speeds, two heating speeds, and two fan-only speeds let you dial in comfort, while a 24-hour on/off timer and electronic controls with an included remote make day-to-day operation straightforward. The slide in-out chassis is a practical touch that simplifies both initial installation and end-of-season removal.

Running on 230/208V power, the LW1216HR delivers an airflow efficiency of 265 CFM and keeps noise down to approximately 50 dB on its lowest setting. The Auto Restart function ensures the unit powers back on with its previous settings after an outage, which is especially useful if you're away from home. While the higher voltage requirement means you may need a dedicated circuit, the trade-off is consistent, efficient cooling and heating performance suited to bedrooms, living rooms, and mid-sized offices.
