- Key Specs
- Recommended Room Size: 1000 square feet (The recommended area size in which the product is designed to operate and produce optimal results, such as the desired heating or cooling. Generally, running a unit too big or too small for the space will result in ineffective operation and wasted energy.)
- BTU Cooling Rating: 18000 british thermal units (The amount of BTUs (British Thermal Units) per hour the unit uses to cool the air, also known as cooling capacity. For best results, the capacity of the unit should be based on the size of the area it is intended to cool. For example, a 5,000 BTU capacity works optimally for a 150 square foot room. In general, an oversized unit will not effectively remove humidity, and an undersized unit will not cool the space efficiently.)

CEER measures the ratio of output BTUs (British Thermal Units) to input electrical energy (watts) in standby mode and while the unit is operating.

Q: Can I install this unit through the wall instead of thru the window?
A: Hi, 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. You can visit this link for our Through the Wall Air Conditioning units: https://www.lg.com/us/wall-air-conditioners For further inquiries, you can reach out to us by sending us a private message through @LGUSSupport on Facebook or Twitter. ^Danee

Customers are saying
Customers consistently note the excellent cooling performance of the 1,000 Sq. Ft. 18,000 BTU 230V Smart Window Air Conditioner, with many praising its ability to effectively cool a space. However, a significant drawback mentioned by several customers is the unit's 230V voltage requirement, which is not compatible with standard wall outlets in many regions. This incompatibility was a source of frustration for some buyers. Clearer communication of the voltage specifications is suggested.
