LG Electronics LT12124CNR 11,800 BTU Through-the-Wall Air Conditioner White

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.
