Info & Guides

Description

In a lot of large rooms, a window air conditioner handles summer and a space heater gets dragged out in winter. The LG 18,000 BTU Wi-Fi Window Air Conditioner w/ Heat does both jobs. It fits a single or double-hung window and keeps large living rooms and open-plan spaces comfortable in every season.

With Wi-Fi, you don't have to be home to manage the room. From the LG ThinQ app, you can switch modes before you get back. Usage reports and maintenance reminders arrive in the same app. On mild days, Fan-Only mode moves air through the room without cooling or heating.

Key Features and Benefits of the LG 18,000 BTU Wi-Fi Window Air Conditioner w/ Heat

  • Dual-Mode Capacity: You get 18,000 BTU of cooling and 12,000 BTU of heating, so this LG air conditioner works through summer heat and cool spring and fall nights.
  • Multiple Control Options: Control it from the electronic LCD panel, the remote control, or the LG ThinQ app, with voice commands via Amazon Alexa and Google Assistant.
  • Measured Sound Levels: It runs at 57 dB on low and 61 dB on high, which is about as loud as a normal conversation.
  • Cooling Temperature Range: Cooling works in outdoor temperatures from 60 to 115 degrees F, so the room stays comfortable during hard summer heat waves.
  • Louvered Airflow: Moves up to 430 CFM through 4-way louvers, so you can aim the air where people actually sit in a large room.
  • Energy Saver Mode: The 11.1 CEER rating and the built-in E/Saver mode, which adjusts operation once the room reaches your set temperature, help you cut energy use.
  • Dry Mode: Dehumidification mode removes up to 2.1 pints of moisture per hour, so humid rooms feel less sticky on muggy days.
  • 24-Hour Timer: You can set the air conditioner to turn on or off at any time within 24 hours, and Auto-Restart brings back your settings after a power interruption.
  • Installation Kit Included: Hardware, adhesive foam, and brackets are included for single or double-hung windows 29 to 41 inches wide and at least 18 inches tall.
  • Certified Construction: UL certified for safety, with R-32 refrigerant that moves heat in and out of the room, plus a washable filter that needs monthly cleaning.

Check Your Window and Circuit Before Installing

This air conditioner measures 35.5 x 25.5 x 16.83-Inches (L x W x H) and weighs 132 pounds, so it is worth getting a helper for the lift. The slide-out chassis comes out of the cabinet, which makes that weight easier to handle while you set it in the window.

On the electrical side, the air conditioner runs on 208 to 230 volts and has a 6-20P plug rated for a 250V-20A circuit, so a standard household outlet will not work. Heating is the bigger load, drawing up to 16.0 amps and 3,670 watts compared with 7.8 amps and 1,640 watts for cooling. Make sure the circuit can carry that winter load before you install.

Sylvane's Expert Take

If you're heating and cooling a large living room or open-plan space up to 1,000 square feet and already have a 230-volt outlet, this LG covers both seasons from 1 window. Before anything else, check your wiring, because heat mode pulls 16 amps. The 12,000 BTU heat mode and the ThinQ scheduling are what matter most here. Set a schedule once, and the room is the right temperature by the time you walk in.
