Description

Big rooms are where smaller window air conditioners fall behind on hot afternoons. The LG 14,000 BTU Smart Wi-Fi Enabled Window Air Conditioner (model LW1521ERSM1) is sized for living rooms and large open spaces. If the power goes out, Auto-Restart brings it back on with your previous settings so you don't have to reset anything.

 

Cool mode handles hot days and also dehumidifies, while fan-only mode moves air around the room without cooling it. Dry mode is meant for damp, rainy weather and removes up to 4.6 pints of moisture per hour, so the room feels less sticky when it's humid but not especially warm.

Key Features and Benefits of the LG 14,000 BTU Smart Wi-Fi Enabled Window Air Conditioner

  • 14,000 BTU Cooling: This capacity handles rooms up to 700 square feet, keeping a large living area comfortable through peak summer heat.
  • LG ThinQ App: Wi-Fi connectivity through the LG ThinQ app (iTunes, Google Play) lets you adjust temperature and switch modes from your phone, plus track your energy use.
  • Voice Control: Compatibility with Alexa and Google Assistant lets you change cooling settings by voice without reaching for your phone or the remote.
  • Remote and Panel: The included remote control and electronic control panel give you 2 more ways to adjust settings, from across the room or at the window.
  • Quiet Fan Speeds: The 3 fan speeds run at 53 dB on low, 54 dB on medium, and 55 dB on high, so noise stays steady in bedrooms and offices.
  • Directional Airflow: Adjustable 4-way air direction with auto swing spreads up to 265 CFM of airflow around the room, helping you avoid warm spots in far corners.
  • Energy Saver Mode: Energy Saver mode and an 11.2 CEER efficiency rating support an estimated yearly operating cost of $122, which keeps long cooling seasons easier on your electric bill.
  • 24-Hour Timer: A programmable on/off timer lets you schedule cooling to start before you get home and shut off after you fall asleep.
  • Washable Filter: The slide-out washable filter comes out without tools, and a filter alarm tells you when it is time to clean it.
  • R-32 Refrigerant: Cooling works across operating temperatures from 60 to 86 degrees F, which covers typical summer conditions.
  • UL Certified: UL certification means the air conditioner has been tested to recognized electrical safety standards, so you can run it daily with confidence.

Check Your Window and Outlet Before You Install

This air conditioner fits single-hung and double-hung windows from 27 to 39 inches wide, with a minimum window height of 16 inches. The installation kit is included, so you can mount it without gathering extra hardware. It measures 23.63 x 22.2 x 15 inches (L x W x H) and weighs 82 pounds, so plan on a second person to help you lift it into place. The slide-out chassis lets you remove the internal components from the cabinet, which makes handling and servicing easier.

The 6-foot cord ends in a standard 5-15P plug for a 110 to 120-volt household outlet. At full cooling, the air conditioner draws up to 11.2 amps and 1,250 watts, so put it on a 115-volt, 15-amp circuit that isn't shared with other high-draw appliances to avoid tripping the breaker.

Sylvane's Expert Take

If you're cooling a large living room or open-plan space between 500 and 700 square feet, this is the right capacity class, because smaller air conditioners tend to run nonstop in rooms that size. Before summer, keep in mind that it cools and dehumidifies but has no heat mode, so you'll need separate heating for winter.

The app control matters most if you want the room cooled before you walk in the door. With a 1-year parts and labor warranty behind it, this LG is a confident pick for big-room summer comfort.
