Rated 2 out of 5 by from Does NOT get cold I’m very disappointed with this product. Even at 69 degrees, it’s only moderately cool. The Wi-Fi feature does not work. I gave it two stars, because of the remote and quiet sound.

I have a LW1811ER LG AC unit I bought in 2011. Do these share same chassis? In other words if I buy this one can I slide this into the Chassis of my old one? I have it built into wall so that could be a huge plus for me. Thanks

Asked by: Wantnewer
Our Window Air Conditioners either have SlideI-Out Chassis or Top-Down Chassis but there have different W x H x D dimensions and they don't fit into the same size windows so they don't all share the same chassis. The chassis are designed for installation in standard single-hung or double-hung windows and they also may not have the same screw placement for the chassis as your older LG 18,000 BTU Window Air Conditioner with remote, Model # LW1811ER...^Ivan

My window is 45 inches wide will this work?

Asked by: Charmbaj
The LG 18,000 BTU Smart Wi-Fi Enabled Window Air Conditioner, Cooling & Heating, Model # LW1821HRSM is designed for installation in standard single-hung or double-hung windows with actual opening widths from 29" to 41". The top and bottom window sashes must open sufficiently to allow a clear vertical opening of 18" from the bottom of the upper sash to the inside sill. The left and right curtain panels for the unit cannot be extended more than 41"...^Ivan
