The LG LS122HE Mini Split Ductless Air Conditioner is a wall mounted, 12,000 Class BTU, single zone AC unit. Some features include both cooling and heating modes, a dehumidifier, super quiet operation, an air purifying system and R410A refrigerant. As a ductless system, it functions much like a central air system, but without the hassle and unattractiveness of invasive ductwork.

Your LG LS122HE Mini Split Ductless Air Conditioner will evenly cool and heat your rooms where and when you want it. With fan mode, heating mode and a temperature display that you can easily control, your home's comfort is right at your fingertips.

The included heat pump in the LG LS122HE Mini Split Ductless Air Conditioner is a two way, reversible pump that transfers heat between indoor and outdoor air. Using a vapor compression system, heat from the outside is delivered inside on the heating cycle and reversed when cooling is desired. A factory warranty is included with your unit, but it must be professionally installed for you to qualify for it.

The LS122HE is a Ductless Mini Split System that consists of a LSN122HE and a LSU122HE.

Please Note: Mini-Split Systems must be installed by a licensed Heating Contractor holding an EPA Refrigerant Certification to qualify for warranty.

Air Conditioner BTU rating / per square foot chart:

(BTU ratings are based on 10ft ceilings, with Very Good insulation and windows -some factors may alter this calculation: lack of insulation, heavy sun, excessively hot regions, & tall ceilings)

To make sure you install a unit is going to properly cool your square footage without excessive stress to the AC unit, installing a unit with redundant power will ensure longer lasting use, with less repair and maintenance. If unsure, use the lower range of the chart above.

I want to install a unit on my third floor. Do I have to have something mounted to the outside of my house on the 3rd floor also?

by Marie P. on 05-30-2012

The LG LS122HE requires a 25ft line set (or shorter) to supply adequate refrigerant to the indoor unit. Therefore, the condenser unit must be within a 25ft proximity.We recommend checking all building and safety codes before attempting an installation of this type.
