Q: If the air conditioner measures a width of 23", why do I need a minimum of 27" wide window opening!?! My window is 26.5 inches wide. Can I make it fit?
2 years ago- A: Hello, PaulaMcL. The reason you need a minimum width of 27" for the 14,000 BTU Smart Wi-Fi Enabled Window Air Conditioner, Model # LW1521ERSM1, is because, like any other window air conditioner, it comes with a left and right panel guide (aka. accordion panels) that attach to the sides of the unit so you can close any openings in the window after installing the air conditioner. The air conditioner has a width of 23.62", which means that for a window with a minimum requirement of 27", you have 1.69" on either side of the air conditioner to work with for installation and the left and right guide panels. That is the smallest width the panel guides can fit in...^Ivan.2 years ago
Q: How wide does the window have to be for this unit to fit. My window has a 26 inch wide opening.
2 years ago- A: The LG 14,000 BTU Smart Wi-Fi Enabled Window Air Conditioner (LW1521ERSM1) is designed for installation in standard double hung windows with actual opening widths from 27 in. to 39 in. The top and bottom window sashes must open sufficiently to allow a clear vertical opening of 16" fro the bottom of the upper sash to the inside sill. For more information about its installation, you may refer to the page 11 of the Owner's Manual on this link: https://www.lg.com/us/support/product/lg-LW1521ERSM1.AT1AUSH -Cazz2 years ago

Anonymous2 years ago- A: The LG 14,000 BTU Smart Wi-Fi Enabled Window Air Conditioner, Model # LW1521ERSM1 is a Window Air Conditioner, and as such, a single-hung or double-hung window is required for proper installation. Non-window installations, including using sleeves or wall openings, and other installation methods are not recommended...^Ivan2 years ago
Q: Can this be installed through the wall?
3 years ago- A: Hi, This unit needs to be vented, therefore window installation is best. If your intention is to install through an outside wall, please reach out to LG and request installation instructions for that application. https://www.lg.com/us/support/contact OR CALL 800-243-00002 years agoHelpful?
