LG DUALCOOL R-410A wall units: two families, from 9,000 to 36,000 BTU/h

“Gloss white” is our label. LG Canada simply says DUALCOOL® and publishes a white cabinet. Under that name, LG has two R-410A families: the HSV5 at 9,000, 12,000 and 18,000, and the HLV3 from 22,000 to 36,000 BTU/h. The 22,000 keeps 21,170 BTU/h at −20°C, more than the same-size R-32 Extended Piping.

Capacities in BTU/h, certified by NEEP (October 14, 2026). At 9,000 and 12,000, the DUALCOOL head shares the outdoor unit and the ratings of the R-410A Art Cool Mirror.

The 22,000

The largest R-410A DUALCOOL, versus the R-32 Extended Piping

The “24,000” listing is a 22,000 in cooling and a 26,000 in heating. At the same size, LG also documents the R-32 Extended Piping KNSAP241A: the R-410A keeps more heat in the cold, the R-32 gets more LogisVert.

Why $790 and not $1,896

LogisVert pays $120 per 1,000 BTU/h rated at −8°C for an ENERGY STAR Cold Climate unit, and $50 for an ENERGY STAR unit without that mention. The R-410A 22,000 is ENERGY STAR certified, not Cold Climate: 15,800 BTU/h × $50 = $790. It is the only wall unit in our LG range paid at that rate.

The same-size R-32 Extended Piping has the same rated output at −8°C (15,800 BTU/h), but the Cold Climate mention: $1,896.

Installation and sound

  • Line set: up to 50 m, with a 30 m rise, per the LG U.S. LS243HLV3 spec sheet, which calls it a “Single Zone Extended Piping Wall Mount”.
  • Weight, per the same sheet: 61.4 kg outdoor unit, 16.6 kg head.
  • Indoor sound pressure published by LG Canada: 49 / 44 / 40 / 30 dB(A).

Versus R-32

From 9,000 to 18,000, what LG also documents in R-32

  • At 9,000 and 12,000, the R-410A DUALCOOL has the ratings of the R-410A Art Cool Mirror, and the R-32 DUALCOOL (KNUAB head) those of the R-32 ARTCOOL Mirror. The full comparison is on the Art Cool Mirror page: more heat at −20°C in R-410A, better SEER2 and HSPF2 in R-32.
  • At 12,000, LogisVert pays $984 for the R-410A and $1,020 for the R-32 DUALCOOL (8,200 versus 8,500 BTU/h rated at −8°C).
  • At 18,000, LG’s LSN181HSV5 pair is listed at $1,560, the R-32 DUALCOOL KNUAB181A at $1,596.

A Montreal benchmark

Both R-410A families heat down to −20°C per LG. At Montréal-Trudeau, the daily low drops below −20°C 12 days a year on average (1991-2020 normals).

The name

Where “gloss white” comes from

What LG writes

  • LG Canada, in English: “DUALCOOL® 9,000 BTU, ThinQ®, Heating, Dual inverter”, the same formula for LSN180HSV5, LSN243HLV3 and LSN363HLV3.
  • LG Canada, in French: “Climatiseur DUALCOOL ThinQ de 12 000 BTU, chauffage, double onduleur” and “Le DUALCOOLMC de LG”.
  • Published colour: White, with no word on the finish. LG uses “Gloss White” only once, as an advertising line (opposite).

Where “gloss” comes from

  • “Fini blanc brillant élégant”: LG Canada’s French brochure for the R-32 DUALCOOL. LG Canada’s English page for the KNUAB091A, for its part, speaks of “A matte finish”. We write “white”, without describing the finish.
  • “LG Gloss White”: an advertising line, used once, on LG Canada’s LSN243HLV3 page.

HSV5 maintenance, per LG

  • Filters: clean them every two weeks, or more often if needed; wash them in lukewarm water, under 40°C, and dry them in the shade.
  • Coils and drains: a professional cleaning once a year.
  • Source: LG U.S. owner’s manual MFL69491102 for the HSV5 wall units (2018). For the HLV3, we have not read an owner’s manual.
  • Features LG Canada lists for the 18,000: EZ slide-out filter, Smart Diagnosis, Jet Cool, Gold Fin and Comfort Sleep.
  • In multi-zone: the LSN090HSV5, LSN120HSV5 and LSN180HSV5 heads also appear in LG’s installation manual for standard Multi F wall heads.
  • Availability: the LG Canada pages for LSN090HSV5, LSN180HSV5, LSN243HLV3 and LSN363HLV3 are online as of October 14, 2026. We confirm availability on the quote.
  • Warranty: LG’s wall-unit warranty, with its registration condition, is explained once, on the LG page.

None of our published projects names the DUALCOOL. The closest: an R-410A LG wall-unit install in Sainte-Thérèse (January 2026) and a repair in Rosemont–La Petite-Patrie (December 2024).

Frequently asked questions

What people ask us most

Is “gloss white” an LG name?
Not as a series name: it is our label. LG Canada calls these wall units DUALCOOL and publishes a white cabinet. “LG Gloss White” appears once, as an advertising line on the LSN243HLV3 page, and LG’s French brochure for the R-32 DUALCOOL speaks of a gloss white finish.
Why does the 22,000 get only $790 of LogisVert?
It is ENERGY STAR certified, but not Cold Climate. Hydro-Québec therefore pays $50 per 1,000 BTU/h rated at −8°C instead of $120: 15,800 × $50 = $790.
DUALCOOL or Art Cool Mirror at 9,000 and 12,000?
Same outdoor units, same certified ratings and the same LogisVert amount. Only the wall head changes.
Does the 18,000 qualify for LogisVert?
The pair LG documents, LSN181HSV5 + LSU181HSV5 (AHRI 207348503), is on the October 27, 2026 list at $1,560. We confirm the exact pair and its amount on the quote.
Are the 30,000 and 36,000 certified?
We found neither their AHRI numbers nor published LG ratings. They are not on the LogisVert list. We confirm the exact model and its ratings on the quote.
