No verified online listing
A window AC is a self-install unit: you set it in the window (or wall sleeve), no contractor or refrigerant charge needed. We have not matched a retail listing for this exact model, so we are not linking one. Search your usual retailer for the model number above — and check the certified specs here against whatever you find.
Sized for ~400 sq ft — measure your room and check your window type before you buy.

Brand, warranty & reliability
LG ductless/VRF is a premium-tier Korean line with strong efficiency and a broad service base, but full 10-12 year coverage hinges on registration and installation by an LG Pro/Excellence contractor, and older (2018-and-earlier) inverter boards had elevated failure rates LG has since addressed.
Reliability is our read of published brand assessments (source), not a certified rating — real-world dependability hinges on a correct install more than the brand. Warranty terms are the manufacturer's (policy) and almost always require online registration within 60–90 days for the full length.

Frequently asked questions
Is 8,500 BTU right for my room, or should I size up?
About 400 square feet is the guide figure, and 6 certified units sit on that shelf. The next shelf up is 10,000 BTU (75 units), about 450 sq ft. Below it, 8,000 BTU (73 units) covers about 350 sq ft. Between two shelves, take the smaller one: oversizing is the usual reason a unit cools but leaves the room clammy, which our sizing calculator explains.
Will the LG LW8024IVSM fit my window?
Measure your window opening first — it needs to be at least 24" wide (the cabinet width), and the unit is about 15" tall and 29" deep, roughly 85 lb. Most double-hung windows fit units in this range with the included side panels, but confirm your window's inside width and minimum height.
Sources. Certification and CEER from ENERGY STAR room-AC data and the DOE compliance certification database. Cooling capacity, dimensions and refrigerant are the manufacturer-certified values. Annual running cost, suggested room size and the percentile are computed by Verified HVAC Data from published ratings and EIA U.S. average electricity prices — see our methodology. Refrigerant GWP is the IPCC value. We publish no star ratings and take no payment for placement. "Not published" means the source registry doesn't disclose it — we never fill a spec with a guess.
