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 1,500 square feet is the guide figure, and 22 certified units sit on that shelf. Below it, 18,000 BTU (17 units) covers about 1,000 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(230V) need a special outlet?
Yes. It runs on 230 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(230V) 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(230V) 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.
