LG LW1816ER 18000 BTU Air Conditioner Price in United States


  • No matter how hot it is outside, keep your home cool with this LG air conditioner. The LG LW1816ER is designed for heavy-weight cooling. Its 18,000 BTU energy output can bring down temperatures in a large room that’s up to 1000 square feet. That’s enough power to make a big impact on large sunny rooms, or air-condition entire apartments (with the occasional strategically placed fan to guide airflow).
  • With an EER (or Energy Efficiency Ratio, found by dividing BTUs by power wattage) of 11.9, the LW1816ER achieves a high level of energy efficiency that’s rarely surpassed by other AC devices. For every one watt of energy used, the device puts out 11.9 BTUs of cooling power. With a rating like that, along with its Energy Star rank, this model makes successful home cooling an economical enterprise.

In-Window Convenience

  • The experts at LG Appliances and Electronics have air conditioners designed to fit in windows and walls, and even some that are portable enough to move from room to room with you. But the LG LW1816ER is a classic, flexible in-window unit. And while central air conditioning takes the gold star in terms of energy efficiency and convenience, the classic window unit perseveres in popularity. This LG air conditioner fuses affordability, high function, and portability for ease of use. When temperatures rise in the spring, simply install in a central area of your room.
  • Air is pulled through the device’s cooling coils, stripping heat and moisture before pushing the chilled breeze back out into the home. A power failure auto-restart function help to ensure cool temperatures even if the power goes out in a disaster, like a storm or extreme heat conditions. As soon as the electricity is back, your AC is back.
