A:AnswerThe LG 800 Sq. Ft. 15,000 BTU Smart Wi-Fi Enabled Window Air Conditioner, Model # LW1521ERSM is designed for installation in standard single-hung or double-hung windows with actual opening widths from 29” to 41”.
It has a width of 25.98", but the minimum window opening width of 29" is for the left and right curtain panels and you will not have enough space between the air conditioner's cabinet and your 26.75" window opening to fit the curtain panels. You could fit it into your window opening, but you will not be able to use the curtain panels and will need to find a different method to close the gap between the unit and your window frame.
The LG 14,000 BTU Window Air Conditioner, Model # LW1424RD has a 22 1/5” width and is designed for installation in standard single-hung or double-hung windows with actual opening widths from 27” to 39” and will not fit into your window for the same reasons above for Model # LW1517ERSM.
The difference between the air conditioners is the BTU rating as you can see from their titles.
14,000 BTU is ideal for cooling large rooms up to 700 sq. Ft., and 15,000 BTU is ideal for cooling rooms up to 800 square feet.
They have different W x H x D dimensions and different CEER ratings, but the same EER rating...^Ivan.
A:AnswerHi there. Thanks for reaching out. For the LG - 800sp. ft. 15,000 BTU Smart Window Air Conditioner has the Window Kit included when purchase. It is not drill free. To prevent vibration and noise, make sure the unit is installed securely and firmly. Install the unit out of direct sunlight. There should be no obstacles, such as a fence or wall, within 20" from the back of the cabinet because it will prevent heat radiation of the condenser. Restriction of outside air will greatly reduce the cooling efficiency of the air conditioner. DO NOT cover or block any of the side and top louvers. All side louvers of the cabinet must remain exposed to the outside of the structure and unobstructed. Install the unit slightly tilted so the back is slightly lower than the front (about 1/2"). This will force condensed water to flow to the outside. Install the unit with the bottom between 30" ~60" above the floor level. *Window Requirements - This unit is designed for installation in standard
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 19" from the bottom of the upper sash to the inside sill. *NOTE - All supporting parts should be secured to firm
wood, masonry, vinyl, fiberglass, or metal. This product is a window air conditioner. As such, a standard 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. *Storm Window Requirements - Windows that include a storm window frame may prevent the air conditioner from tilting down toward the outside to drain properly. For proper drainage, attach a 2" x 2" piece of wood to the inner sill, trimmed to a length which fits inside the window frame. The top of the wood shim must be at least 1 1/4" higher than the top of the storm window frame. Attach the wood securely to the sill with nails or screws. If necessary, attach another 2" x 2" wood strip flush against the back of the inner sill. `Jai.
