LG wall-mounted heat pumps: the right series for your winter, your room and your line set

Q: Which LG wall unit heats at the lowest temperature?

The ARTCOOL Deluxe: LG rates its heating down to -35°C, and NEEP still certifies 9,100 BTU/h at that temperature for the 12,000. Next come the ARTCOOL Premier and the DUALCOOL PRESTIGE, down to -25°C.

32 LG wall-mounted heat pumps for sale, in R-32 and R-410A, across nine series. They do not handle the cold the same way: LG rates heating down to −35°C for the ARTCOOL Deluxe, −25°C for the ARTCOOL Premier and the DUALCOOL PRESTIGE, and −20°C for the rest. This page compares them at the same capacity, with certified figures.

A Montréal winter

Slide the temperature: how much heat is left

At Montréal-Trudeau the daily minimum drops below −20°C about 12 days a year, and below −30°C roughly one winter in five (1991-2020 normals). Below its series’ limit a wall unit stops, and the house needs backup heat.

LogisVert

The amount follows the heat at −8°C, not the deep cold

89,000 BTU/h wall listings absent from the LogisVert list

$790the only LG wall unit at the $50 rate, for lack of Cold Climate certification

Hydro-Québec requires a nominal cooling capacity of at least 12,000 BTU/h. No 9,000 qualifies, not even the Deluxe, Cold Climate certified down to −35°C.

What LogisVert does not look at

The amount is based on the certified rated output at −8°C. The Deluxe 12,000 holds the deep cold far better than the Mirror, yet gets $12 less: 8,400 versus 8,500 BTU/h at −8°C.

Hydro-Québec LogisVert list of October 27, 2026, to be confirmed by Hydro-Québec when you apply. $120 per 1,000 BTU/h for an ENERGY STAR Cold Climate unit, $50 otherwise (participation guide, version 1.10).

Installation

How far the line set can run

Between the outdoor unit and the head, LG sets a maximum length per series and capacity. That figure often decides the series when the room sits far from an outside wall.

Defrost: LG Canada’s Prestige, Mirror and DUALCOOL brochures list a heating element built into the condensate pan.
Cooling in cold weather: down to −18°C with LG’s optional wind protection kit (Premier, Mirror, DUALCOOL).

Two generations

R-410A or R-32: what the numbers say

Still sold, still certified

The certified R-410A models on this page are still certified by NEEP and ENERGY STAR as of October 14, 2026, appear on Hydro-Québec’s list when they are 12,000 BTU/h and up, and LG Canada still lists them. LG has also documented its R-32 wall units since spring 2025 (LG Canada brochures of March and April 2025).

A web page says nothing about production: we confirm availability on the quote.

What the generation changes, at the same capacity

At 9,000 and 12,000, the R-410A ARTCOOL or DUALCOOL gives more heat at −20°C than the R-32 Mirror or DUALCOOL (10,360 versus 8,010 BTU/h at 12,000), but the R-32 has the better SEER2 and HSPF2.
At 15,000, 18,000 and 22,000, the R-410A DUALCOOL PRESTIGE keeps more heat at −25°C than the R-32 ARTCOOL Premier (17,740 versus 14,780 BTU/h at 22,000), with the same SEER2.
The R-32 Deluxe matches the SEER2 and HSPF2 of the DUALCOOL PRESTIGE 9,000 and 12,000 and goes down to −35°C instead of −25°C.

Same outdoor units, same figures: the R-32 Mirror and DUALCOOL from 9,000 to 18,000 share the KUSAB outdoor units and identical certified ratings; only the head differs.

AirGreen has published 25 LG wall-unit projects, in Montréal, Laval, the South Shore and the North Shore. None names the series installed, so our series pages do not use them as proof.

Frequently asked questions

What people ask us most

Which LG wall unit heats at the lowest temperature?

The ARTCOOL Deluxe: LG rates its heating down to −35°C, and NEEP still certifies 9,100 BTU/h at that temperature for the 12,000. Next come the ARTCOOL Premier and the DUALCOOL PRESTIGE, down to −25°C.

Why does a 9,000 BTU/h wall unit get no LogisVert amount?

Hydro-Québec requires a nominal cooling capacity of at least 12,000 BTU/h. The eight 9,000 listings in our LG range are not on the list, however well they handle the cold.

Why is the “24,000” wall unit rated at 22,000 BTU/h?

The title follows LG’s size class. The certification gives 22,000 BTU/h in cooling and 24,000 (R-32) or 26,000 BTU/h (R-410A) in heating. Our pages show both.

ARTCOOL Mirror or DUALCOOL: what is the difference?

At the same capacity, none in the numbers: same KUSAB outdoor unit, same certified ratings. The Mirror has a mirror front, a refrigerant leak sensor and LG also presents it for multi-zone use; the DUALCOOL has the lightest head.

How long a line set does an LG wall unit take?

20 m for the Deluxe, 25 m for the Mirror and DUALCOOL 9,000 and 12,000, 35 m for their 18,000, and 50 m for the Premier and the Extended Piping.

Should I pick R-32 or R-410A?

Both generations are certified. At the same capacity R-32 wins on seasonal efficiency, while some R-410A units keep more heat in deep cold. The “Same capacity” table on this page puts them side by side.
