LG ARTCOOL Premier: 15,000 to 22,000 BTU/h for the big room, down to −25°C

The most powerful ARTCOOL wall unit in R-32: 15,000, 18,000 and 22,000 BTU/h in cooling. On the 15,000 and 18,000 it keeps 100% of its rated heat at −15°C, then heats down to −25°C. Its line set runs up to 50 m, with 30 m of rise: the head can sit far from the outdoor unit.

Deep cold

100% at −15°C, then down to −25°C

LG’s published heating range runs from −25°C to 18°C. Read the brochure’s table rather than its opening text: 100% of rated output is at −15°C, on the 15,000 and 18,000. At −25°C, 69, 68 and 62% of it is left.

The “24,000” model

The “24,000” cools 22,000, and heats like the 18,000 in deep cold

The KSSAL241A carries a 24 in its model number and is listed as a “24,000” on our product pages. Its certified cooling rating is 22,000 BTU/h; 24,000 BTU/h is its rated heating at 8.3°C.

So the choice comes down to cooling and mild-day heat: the “24,000” for a large sunny room or an open-plan space to cool, the 18,000 if winter is the main concern, with an HSPF2 of 11.0 versus 10.2. LogisVert, for its part, pays more for the “24,000”: $1,896 versus $1,572, because its rated output at −8°C is higher.

Premier at LG U.S., Prestige in LG Canada’s French

LG Canada’s French brochure calls it ARTCOOL Prestige; LG sells it in the U.S. as Art Cool Premier, and the Canadian document code reads “ArtCool_Premier”. Same models: KSSAL151A, KSSAL181A and KSSAL241A.

Not to be confused with the Art Cool Prestige R-410A, a different series, in 9,000 and 12,000 only.

Against the other LG wall units

Three comparisons, at the same capacity

Each tab sets the Premier beside an LG wall unit of the same capacity from another series. The full ladder of series is on the LG wall-unit page.

At 18,000 the Premier heats five degrees lower and takes 15 more metres of line set: it is the R-32 wall unit to pick when the head is far from the outdoor unit.

LG Canada ARTCOOL Prestige, ARTCOOL Mirror and DUALCOOL brochures (2025); NEEP, October 14, 2026; Hydro-Québec, October 27, 2026. The 18,000 Mirror and DUALCOOL share the KUSAB181A outdoor unit and the same ratings.

What LogisVert pays, and what the big head needs

LogisVert

$1,30815,000
$1,57218,000
$1,896“24,000”

Each amount equals the certified rated output at −8°C (10,900, 13,100 and 15,800 BTU/h) × $120 per 1,000 BTU/h, the ENERGY STAR Cold Climate rate. They are the same amounts as the R-410A DUALCOOL PRESTIGE of the same size, whose rated output at −8°C is identical.

Indicative amounts, Hydro-Québec list of October 27, 2026, to be confirmed when you apply. The program rules are on the LG page.

At installation

  • 50 m of line set at most (164 ft) and 30 m of rise; refrigerant pre-charged for 7.5 m, then 0.32 oz per foot.
  • Electrical protection: MCA of 19 A, MOP of 30 A, on all three sizes.
  • A 106 cm wide indoor unit weighing 17.1 kg: we check the wall and the space above the furniture during the visit.
  • A 61.4 kg outdoor unit (37 13/32 × 32 3/4 × 13 in), from the same KUSAL family as the Deluxe’s, but bigger (45 kg for the Deluxe).
  • Sound: 49 down to 30 dB(A) indoors depending on fan speed; 55 and 56 dB(A) outdoors.

LG Canada’s brochure for the series names its LGRED° heating technology.

Frequently asked questions

What people ask us most

ARTCOOL Prestige or Art Cool Premier: is it the same unit?
Yes. LG Canada calls it ARTCOOL Prestige in French, LG U.S. calls it Art Cool Premier. The models are the same: KSSAL151A, KSSAL181A and KSSAL241A.
Does the Premier deliver 100% of its heat at −25°C?
No. Per the LG brochure’s table, it delivers 100% of its rated output at −15°C on the 15,000 and 18,000 (90% on the “24,000”), then 69, 68 and 62% at −25°C.
Does the “24,000” heat more than the 18,000 in deep cold?
No. LG publishes exactly the same maximum output for both at −8°C, −15°C, −18°C and −25°C (14,780 BTU/h at −25°C). The “24,000” cools more (22,000 versus 18,000 BTU/h).
How much does it heat at −20°C?
LG does not publish the maximum output at −20°C for this series, only the COP (1.74 on the 15,000, 1.72 on the 18,000 and “24,000”). The nearest published point is −18°C: 16,290 BTU/h, 19,520 BTU/h and 19,520 BTU/h.
How far can the head be from the outdoor unit?
Up to 50 m of line set, with 30 m of rise. Refrigerant is pre-charged for 7.5 m; beyond that we add 0.32 oz per foot.
How is it different from the Art Cool Prestige R-410A?
They are two series. The Art Cool Prestige R-410A comes in 9,000 and 12,000; the ARTCOOL Premier R-32 starts at 15,000 and goes up to 22,000 BTU/h in cooling.
Where do the Premier’s LogisVert amounts come from?
From the certified rated output at −8°C: 10,900, 13,100 and 15,800 BTU/h, at the Cold Climate rate of $120 per 1,000 BTU/h: $1,308, $1,572 and $1,896.
