Room coverage and cooling capacity

The LG LT12124CNR delivers 11,800 BTU of cooling power designed for medium rooms up to 530 sq. ft. It mounts in a through-the-wall sleeve that is sold separately and ships in white finish with a trim kit included. Three cooling and fan speeds let you match airflow to the room conditions. A 24 hour on/off timer and energy saver mode help manage daily run time.

Buyers needing permanent wall installation versus

This unit suits homeowners or landlords who can cut a wall opening and install the required sleeve for a fixed, secure fit. It is not for renters or anyone who needs a window-mounted or portable air conditioner that can move between rooms. Buyers who want heating capability should look at a different model because this appliance provides cooling, dehumidifying and air circulation only.

Steady output during extended operation

With three fixed fan speeds the airflow remains consistent whether the compressor cycles on or runs continuously through a hot afternoon. The power failure auto restart returns the unit to its previous settings without manual intervention after an outage. A removable washable filter and check filter alert keep airflow steady over weeks of use by prompting cleaning before restriction builds up.

Questions about this item

What wall sleeve do I need to install the 11,800 BTU through-the-wall air conditioner?

The wall sleeve is sold separately and must be purchased to fit the unit into your wall opening.

Can the 4-way air deflection work with my existing window unit in the same room?

The 4-way air deflection directs airflow from this unit only; it does not interact with or control a separate window unit.

How do I know the auto restart feature activated after a power outage?

The digital control panel will display the previous settings and the unit will resume cooling automatically once power returns.
