HOT ! LG KNUAK181A Art Cool Smart Wall Mounted Indoor Unit with 18000 BTU Cooling, 21600 BTU Heating Capacity and Remote Control in Mirror

LG\'s devotion to providing efficient ductless solutions can be seen across the Multi F line of indoor units. Their Art Cool Mirror mini split indoor units are a brilliant blend of sleek aesthetics and clever engineering, making them a great option for any room that needs a heating and cooling solution that won\'t disrupt the space\'s design. The unit\'s  mirrored front panel may be the most eye-catching aspect of the unit, but the versatility of its operating modes and reliability of its components cannot be overstated.

Enhanced Connectivity

LG\'s new R-32 mini split units require a 5-conductor cable (Not Included) instead of the standard 4-conductor, improving communication reliability and enabling a new leak detection feature.

Built-In Wi-Fi

The unit has built-in Wi-Fi, enabling the control of your LG air conditioner with smart enabled devices. Simply download the SmartThinQ® app on your smart device to get started.

Air Flow Options

This unit gives you two options for automating air flow. In Swing Mode, the unit will rotate through all four air flow directions to ensure consistent comfort in every corner of your room.

Quiet Design

The unit can operate at volumes as low as 34 dB thanks to a combination of cutting edge components. LG utilizes a cross flow fan design that reduces noise levels by limiting the surface pressure of air flow.

Self-Cleaning Coil

The unit features a self-cleaning heat exchanger coil that automatically removes dirt and moisture. This helps to prevent unpleasant odors and to combat the formation of mold.

Jet Temperature Control

Quickly get your zone comfortable with the Jet Heat and Jet Cool modes. With the press of a button, your system will temporarily adjust the set point and fan speed to provide rapid heating or cooling.

Automated Operation

Auto operation mode continually compares your zone\'s current and desired temperatures and uses that data to intelligently adjust the unit\'s fan speed and refrigerant flow to provide optimal comfort.

Sleep Mode

With the Sleep Mode and Timer functions, you can set this indoor unit to save energy at night. Sleep Mode will incrementally adjust temperature for an hour before the Timer function automatically deactivates the unit.

Dehumidify

LG\'s indoor units include a dehumidifying operation mode. In this mode, the unit\'s internal sensors monitor temperature and modify the set point and fan speed to remove moisture from the air.

Improved Air Quality

The unit uses a dual filtration system to keep your air clean. A washable anti-fungal filter protects against dust and bacteria, while a 3M Micro Protection Filter captures microscopic irritants for pristine air quality.

Hot-Start

When the Hot-Start function is enabled, the unit\'s fan will not engage until the outdoor condenser has had the opportunity to warm the indoor coil. This prevents the unit from blowing cold air during heating operations.
