LG LW2422IVSM(208V)
window air conditioner · 23,500 BTU cooling · fits ~1,175 sq ft
A window AC rated 23,500 BTU — enough cooling for a room of roughly 1,175 square feet (the 20-BTU-per-square-foot rule).
What actually decides this purchase
We publish 22 units at 24,000 BTU. They run within $38 a year of each other — but they sell for $635 to $1,115, a 1.8× spread. Efficiency is not what decides this purchase at 24,000 BTU; price, noise and whether it fits your window are. Here is where this unit lands.
We have no tracked price for this unit, so here is the rule instead. At 24,000 BTU the field runs $635 to $1,115, median $635, and every one of them runs within $38 a year of every other — so price is the decision and efficiency is the tiebreak. On the certified specs we do hold, this one ranks 1st of 22 in its class. If the price you are quoted is above $635, buy something else. Worth comparing against the Midea MAW24R2VWT at $635 and the Friedrich CCV24A30A at 32 dBA for $1,115.
Price
Not tracked
We have no verified retail listing for this certificate. Units at this size run $635–$1,115.
Noise
Not published
The maker publishes no dBA figure we could verify, and noise is not part of the DOE certification. It is the most common complaint about window units, so treat its absence as a real unknown.
Window fit
Measure first
No trustworthy cabinet width on this certificate, so we will not state a fit range.
Circuit
208V needed
Needs a dedicated circuit. Budget an electrician before you buy.
We do not have price or noise or window fit for this unit and will not estimate them. Everything above that carries a number is from a certification record or the manufacturer's own published sheet.
Buy this unit
Sold on Amazon — DIY install
A window AC is a self-install unit: you set it in the window (or wall sleeve), no contractor or refrigerant charge needed. We could not confirm a listing for this exact model number, so this opens an Amazon search for a LG window AC of this capacity — one we checked returns real results. Compare whatever you find against the certified specs above.
Sized for ~1,175 sq ft — measure your room and check your window type before you buy.

Fit & install — does it fit your window?
Efficiency & running cost — computed by Verified HVAC Data
Worth keeping in proportion: every unit in the 24,000 BTU class runs within $38 a year of every other. The gap between the cheapest and dearest to buy at this size is 13× larger. Efficiency is the smallest number on this page, which is why it is not at the top of it.
Refrigerant & identity
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 23,500 BTU right for my room, or should I size up?
About 1,175 square feet is the guide figure, and 22 certified units sit on that shelf. Below it, 18,000 BTU (17 units) covers about 900 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.
Does the LG LW2422IVSM(208V) need a special outlet?
Yes. It runs on 208 volts, not the 115-volt outlet a bedroom or living room normally has, so it needs a dedicated circuit installed by an electrician. Budget for that before you buy: most units in its 24,000 BTU class are 115-volt, so a same-size alternative may avoid the wiring entirely.
Does the LG LW2422IVSM(208V) qualify for efficiency rebates?
It meets ENERGY STAR Most Efficient, the top tier some utility rebate programmes require. 5 of the 22 units in its 24,000 BTU class reach that tier, so it is one of several options at this size. Rebates are set by your state and utility, not by the manufacturer — check the programmes for your area.
Will the LG LW2422IVSM(208V) fit my window?
The certification record doesn't publish reliable full dimensions for this unit, so measure your opening and compare against the seller's listing before you buy.
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.
