Can I install this unit through the wall instead of thru the window?
Answered by LG Digital Customer CareHi, there! The LG 18,000 BTU Smart Wi-Fi Enabled Window Air Conditioner, model LW1821ERSM window air conditioner is designed specifically for window installation and is not intended to be installed through the wall. Installing it through the wall could lead to improper airflow and ventilation, affecting its performance and efficiency. For through-the-wall installations, you would need a different type of air conditioner specifically designed for that purpose, such as a wall-mounted or through-the-wall air conditioner. These units have a different form factor and typically come with a rear or side vent to expel the hot air outdoors. If you are looking for an air conditioner for a through-the-wall installation, make sure to select a model that is explicitly labeled and designed for this type of setup. Installing the wrong type of air conditioner could lead to safety hazards and performance issues.
