The alliance of design and performance for the harshest Quebec winters

At AirGreen , we've installed hundreds of wall-mounted heat pumps across Montreal, Laval, Longueuil, the North Shore, and the South Shore , and few units embody the balance of technology, energy efficiency, and elegance like the LG ARTCOOL DELUXE R32 12,000 BTU (-35°C) . Designed to perform in the most extreme climates, this unit combines award-winning Red Dot 2024 design , artificial intelligence (AI Air) , and stable heating down to -35°C , to provide consistent comfort throughout the year.


A heat pump designed for the Quebec climate

The LG ARTCOOL DELUXE model is a benchmark in residential heating and air conditioning . With its DUAL Inverter Heat Pump compressor and R-32 refrigerant gas , it consumes up to 70% less energy than non-inverter models while ensuring 40% faster cooling .
Its exceptional energy efficiency (SEER2: 25.5 / HSPF2: 11.2) allows it to obtain ENERGY STAR® Cold Climate certification , entitling it to a Hydro-Québec grant of $1,008 .

Heating capacity: 100% at -25°C, maintained at over 70% at -35°C.
Cooling capacity: 12,000 BTU.
Noise level: as low as 21 dB(A) indoors — virtually inaudible.


Behind the performance: exclusive LG technologies

AI Air: intelligent comfort

Thanks to an integrated radar sensor , AI Air technology detects the presence and position of occupants to automatically adjust the direction and power of the airflow. The result: optimal comfort without direct airflow, and intelligent reduction of consumption when the room is empty.

DUAL Vane: absolute control of airflow

The two motorized dampers direct hot or cold air up or down, reaching up to 22 m in range and providing 23% faster cooling than a previous generation. The air is distributed evenly, ideal for the open spaces typical of Montreal condos.

Soft Air: the gentle breeze on demand

When the desired temperature is reached, Soft Air mode reduces the direct flow to maintain a comfortable atmosphere without feeling cold. This feature is particularly appreciated in bedrooms and home offices.

Freeze Cleaning: complete automatic cleaning

This innovative feature freezes and then defrosts the evaporator to eliminate 99% of bacteria (TÜV Rheinland test). Maintenance becomes simple and hygienic: a major asset for indoor air quality.


A connected and energy-efficient heat pump

Thanks to the LG ThinQ™ app, the ARTCOOL DELUXE can be controlled remotely from your smartphone. You can:

  • Turn the unit on/off wherever you are;

  • Adjust the temperature;

  • Enable Proactive Power Saving Mode ;

  • Plan your operating hours.

Additionally, the open window detection function automatically stops heating or air conditioning when a sudden drop in temperature is detected: another way to save money without compromising on comfort.
