LG DUALCOOL PRESTIGE R-410A wall units: the heat left at −25°C
LG Canada sells these wall units as the DUALCOOL® PRESTIGE, with “−25°C Hyper Heating operation” in the title. It is LG’s cold-climate wall unit in R-410A: from 9,000 to 22,000 BTU/h in cooling, it still delivers 17,740 BTU/h at −25°C on the largest size. Here are its certified figures and, at the same capacity, what LG’s R-32 wall units do better and worse.

The name and the generations
Why you sometimes read “−30°C”
The HYV1 and HYV2 generations carried “−30°C” in their titles. The HYV3 we sell heats down to −25°C, per LG and per the coldest test point NEEP publishes.
What LG writes
LG Canada, in English: “DUALCOOL® PRESTIGE 9,000 BTU, ThinQ®, −25°C Hyper Heating operation”.
LG Canada, in French: the same DUALCOOL PRESTIGE ThinQ name, with the same hyper heating claim at −25°C.
LG in the United States: the LAN090HYV3 + LAU090HYV3 pair is called the Art Cool™ Premier (system LA090HYV3).
Cabinet colour published by LG Canada: white.
The name lives on: LG Canada still titles the R-32 outdoor unit KUSAL091A, the one of the ARTCOOL Deluxe 9,000, “DUALCOOL Prestige”.
Three generations, then R-32
1st generationHYV1
LG Canada pages still online, SEER ratings (older standard) and “−30°C” titles.
2nd generationHYV2
LG Canada page for the 15,000 still online.
3rd generationHYV3, the one we sell
SEER2 and HSPF2 ratings, “−25°C” titles: still listed by LG Canada and certified as of October 14, 2026.
2025R-32 wall units
In its 2025 brochures, LG Canada also documents the ARTCOOL Deluxe and the ARTCOOL Premier in R-32, from 9,000 to 22,000 BTU/h.
A Montreal benchmark: at Montréal-Trudeau, the daily low drops below −20°C 12 days a year on average, and below −30°C 0.21 day a year (1991-2020 normals).

The listing sold as “24,000 BTU” (LAN240HYV3) is rated 22,000 BTU/h in cooling and 26,000 BTU/h in heating. Sound pressure as published by LG Canada for the 9,000, 12,000 and 24,000, from high speed to the lowest mode. The 15,000 and 18,000 ratings come from NEEP and ENERGY STAR.
Versus the R-32 wall units
What LG also documents in R-32, at the same capacity
LG Canada also documents R-32 wall units at the same capacities: the ARTCOOL Deluxe at 9,000 and 12,000, the ARTCOOL Premier from 15,000 to 22,000. SEER2 is the same at every size. The gap is in the deep cold, and it changes direction with the size.

What the DUALCOOL PRESTIGE does better
More heat at −25°C than the same-size R-32 ARTCOOL Premier, at 15,000, 18,000 and 22,000.
More heat at −15°C at 15,000 (18,950 versus 18,000) and 22,000 (23,700 versus 21,600); a tie at 18,000.
The same LogisVert amount as the R-32 ARTCOOL Premier at 15,000, 18,000 and 22,000: the rated output at −8°C is identical.
What the R-32 wall units do better
ARTCOOL Deluxe, 9,000 and 12,000: heating down to −35°C instead of −25°C, more heat at −15°C and −25°C, equal or better HSPF2, and $1,008 of LogisVert at 12,000 versus $996.
ARTCOOL Premier, 15,000 to 22,000: a slightly higher HSPF2 in region IV, and in region V at 15,000 and 18,000.
Each cell: DUALCOOL PRESTIGE R-410A / same-size R-32 wall unit. BTU/h. “—”: not on the LogisVert list (under 12,000 BTU/h). Identical SEER2 at every size. NEEP and ENERGY STAR (October 14, 2026), LG Canada 2025 brochures, LogisVert list of October 27, 2026.
Features LG Canada lists for the 24,000: Jet Cool, Smart Diagnosis, Dual Inverter compressor, Micro Filter and Gold Fin coating.
Your model numbers: LAN…HYV3 on the wall head, LAU…HYV3 on the outdoor unit. Note them before you call, for maintenance as for a repair.
Availability: the LG Canada pages for LAN090HYV3, LAN120HYV3 and LAN240HYV3 are online as of October 14, 2026, with no discontinuation notice. 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 PRESTIGE. The closest: an R-410A LG wall-unit install in Sainte-Thérèse (January 2026) and a repair in Rosemont–La Petite-Patrie (December 2024).
Not the HYV3 generation we sell: LG and NEEP rate it down to −25°C. The “−30°C” comes from the titles of the HYV1 and HYV2 generations.
DUALCOOL PRESTIGE or R-32 ARTCOOL Premier: which heats better?
At −25°C, the DUALCOOL PRESTIGE: 17,740 versus 14,780 BTU/h at 22,000. SEER2 is the same, the ARTCOOL Premier has a slightly higher region IV HSPF2, and LogisVert pays both the same amount.
Why is the “24,000” rated at 22,000 BTU/h?
The certification gives 22,000 BTU/h in cooling and 26,000 BTU/h in heating. The listing title follows LG’s model number, LAN240HYV3.
Does the 9,000 BTU/h qualify for LogisVert?
No. It is ENERGY STAR Cold Climate certified, but Hydro-Québec requires at least 12,000 BTU/h of cooling.
Art Cool Premier, Art Cool Prestige, DUALCOOL PRESTIGE: is it the same unit?
In the United States, LG sells the LAN090HYV3 + LAU090HYV3 pair as the Art Cool Premier. Our “Art Cool Prestige” 9,000 and 12,000 listings carry the same AHRI numbers as the DUALCOOL PRESTIGE 9,000 and 12,000.
