The LG LW2521ERSM is not only cool...it's SMART! Cool your home from anywhere using LG ThinQ technology to control your air conditioner with your phone or use Amazon Alexa and Hey Google to control the sound of your voice. This quiet unit is ideal for cooling large rooms up to 1,560 sq. ft. The unit has 3 cooling and fan speeds and a 24-hour timer to create a cooling schedule. 4-way air deflection lets the flow of air be directed where it's needed most whether cooling, dehumidifying, or just circulating air. If there is a power outage, the auto restart feature will automatically turn your unit back on when power is restored. Other features include a remote control, an easy window installation kit, a slide-out (washable) filter, and a check filter alert.
