Lg Electronics LT1233HNR Window Ac with Heat 550 Sq Ft

Product Description

The LG ELECTRONICS LT1233HNR is a window and through-the-wall air conditioner with integrated heating capability, designed for residential and light-commercial single-room applications. It delivers cooling across up to 550 square feet with an EER rating of 9.7 and a CEER rating of 11.6, indicating solid efficiency performance for its class. Airflow is rated at 290 CFM across two fan speeds. At 91.3 pounds, the unit is sized for standard window or sleeve installations and is typically serviced by HVAC technicians or experienced contractors.

This unit is suited for residential bedrooms, living rooms, offices, and similar single-zone spaces up to 550 square feet. The through-the-wall mounting option makes it compatible with sleeve-style wall installations in addition to standard double-hung window openings. The two-speed fan allows for basic airflow adjustment. The air-cooled vented cooling method means the unit exhausts heat directly to the outside, requiring an exterior-facing installation. Both cooling and heating functions are built in, eliminating the need for a separate supplemental heater in moderate climates.

Installation Notes

Installation should be performed by a qualified HVAC technician or contractor familiar with local electrical codes, including applicable NEC requirements for dedicated circuits. Disconnect power at the breaker before handling wiring connections. Verify that the window frame or wall sleeve dimensions match the unit footprint of 20 inches wide by 24 inches tall before mounting. Do not operate the unit without proper exterior venting, as the air-cooled vented design requires unobstructed exhaust to the outside.
