Good fit for
This unit suits homeowners or renters with pre-existing through-the-wall openings. It fits bedrooms, living rooms, and apartments needing robust cooling. The 11,800 BTU output handles spaces up to 530 square feet effectively. If you value energy efficiency, the 10.6 EER and R-32 refrigerant are key benefits. The included remote and washable filter add convenience. You should choose this if you have the correct wall cutout dimensions and need a permanent, high-output cooling solution.
Who can skip it
Skip this model if you only have a standard window. The listing states it is not properly vented for window installation. You must have a wall cutout measuring 25.88 inches wide by 16.72 inches long. If you need a portable unit, this is not it. The 115V voltage requires a specific outlet type. Buyers seeking window-mounted simplicity or portability should look elsewhere. Ensure you can accommodate the 24-inch width and 20.1-inch depth before purchasing.
Verdict
The LG 11,800 BTU Through the Wall AC is a solid choice for spaces with existing wall openings. Its high EER and included accessories make it practical for bedrooms and living rooms.
Key specs for this LG unit
11,800 BTU
This cooling capacity determines how much heat the unit can remove from a room per hour. The listing states it cools spaces up to 530 square feet. You should match this rating to your room size to avoid undercooling or wasting energy. Larger rooms may require higher BTU models, while smaller spaces might be overcooled by this output.
10.6 EER
The Energy Efficiency Ratio measures how much cooling you get per watt of electricity. A ratio of 10.6 indicates solid efficiency for a wall-mounted unit using R-32 refrigerant. Higher EER values mean lower operating costs. You can compare this figure with other 11,000 to 12,000 BTU units to see which offers better long-term value for your energy bills.
115V
This voltage rating means the unit plugs into a standard household outlet. You do not need special high-voltage wiring or a dedicated circuit breaker for a higher amp. This makes installation simpler for most apartments and homes. Always verify that your local outlet can handle the load, but this standard voltage fits typical residential electrical systems in the US.
24” W x 20.1” D x 14.4” H
These physical dimensions define the space the unit occupies. The width of 24 inches is wider than many window units, so you must ensure your wall cutout is large enough. The depth and height also matter for clearance. Check your wall hole measurements against the required cutout size of 25.88 W x 16.72 L x 15.53 H to ensure a proper fit.
Design and build details
The unit measures 24 inches wide by 14.4 inches high and 20.1 inches deep. It weighs 76 pounds. The finish is bright white according to the listing. This color choice helps it blend into most interior walls without drawing attention. The casing is designed specifically for through-the-wall mounting. It is not built for standard window frames. You need a wall cutout that is 25.88 inches wide and 15.53 inches high. The depth of the unit fits within this opening.
A plastic mesh grille protects the outdoor side. This grille shields the internal components from debris. Inside, you get a washable and reusable filter. This feature simplifies maintenance. You can rinse it instead of buying replacements. Insulation foam is also included. This foam helps seal gaps around the unit to improve efficiency.
Controls are handled via a remote control. You do not need to reach the unit to change settings. The listing includes a trim kit for the indoor side. This kit gives the installation a finished look. The layout is compact for its capacity. You place it in bedrooms, living rooms, or apartments. The design prioritizes secure wall mounting over portability. You install it once and leave it there.
Installation and daily operation
This unit requires a dedicated through-the-wall opening rather than a standard window frame. You must cut your wall to match the specified dimensions of 25.88 inches wide by 16.72 inches long and 15.53 inches high. The listing includes a trim kit to finish the indoor side and a plastic mesh grille for the outdoor exposure. You will also install the provided insulation foam to seal gaps. The unit operates on a standard 115V electrical circuit, which is common in most homes. You do not need special high-voltage wiring for this model. Daily use is managed via the included remote control. You can select from three cooling speeds to adjust airflow intensity. There are three pre-programmed modes to choose from. Cool mode delivers cold air for immediate comfort. Dry mode removes excess moisture from the air without lowering the temperature significantly. Energy Saver mode runs the fan to circulate air but shuts off the compressor once your target temperature is reached. This cycle helps maintain temperature without continuous compressor operation. The washable, reusable filter allows you to clean it easily without buying replacements. The turbo fan feature provides a burst of cooling power when needed. You can monitor the unit’s status using the remote. The system uses R-32 refrigerant, which is noted for its energy efficiency. This setup process is straightforward if you have the correct wall cutout ready.
Before You Buy This LG Wall Unit
You need to verify your electrical setup before ordering. This model requires a standard 115V outlet. If your space only has 230V circuits, this unit will not work. You must also confirm your wall cutout dimensions match the required 25.88 by 16.72 inches. The listing includes a trim kit and remote, but you should check if you need additional mounting hardware for your specific wall type. Upkeep is simple. The washable, reusable filter needs regular cleaning to maintain airflow and efficiency. Since this is a through-the-wall unit, it fits differently than window models. It suits bedrooms and small living rooms up to 530 square feet. If you need a portable option or a window-mounted unit, look elsewhere. This LG model is strictly for permanent wall installation. Check your room size against the 11,800 BTU rating to ensure proper cooling. Do not attempt to use it in a window frame, as it lacks the necessary venting for that setup.
Check before you buy
- Confirm you have a 115V electrical outlet nearby.
- Measure your wall opening for the 25.88 by 16.72 inch cutout.
- Check if your room is under 530 square feet.
- Ensure you can make a permanent through-the-wall installation.
