Intelligent comfort and precise control

  • AI Air with radar sensor : the blower adapts according to the ambient temperature and your position, to avoid direct air currents when resting or sleeping.

  • DUAL Vane : Directs air up or down to heat faster in winter and cool faster in summer, with an air throw of up to ~22 m depending on conditions.

  • Soft Air : a gentle, indirect breeze when the set point is reached — ideal for living rooms and bedrooms.

  • Sleep Timer+ : a night mode that remembers your preferences and stabilizes the temperature without over-consuming.

  • Window Open Detection : automatically reduces power when there is a sudden drop in interior temperature (window open), limiting energy losses.

Hygiene, maintenance and longevity

  • Freeze Cleaning : automated internal frost/defrost cycle that removes and removes dust and dirt from the evaporator for enhanced hygiene.

  • Washable pre-filter : captures large particles and cleans with warm water every two weeks during heavy use.

  • Auto Clean+ (via ThinQ): automated drying of the exchanger after shutdown to limit residual humidity and odors.

  • Remote monitoring (LG ThinQ): notifications, consumption monitoring (kW Manager, depending on model), and setpoint adjustments from outside.

Heating performance: designed for Quebec
The ARTCOOL Deluxe 15,000 BTU is sized to provide stable heating in urban Montreal (townhouses, duplexes, condos) and suburbs (cottages, well-insulated bungalows). The Dual Inverter Heat Pump compressor maintains high efficiency in cold weather and remains functional at -35°C . In the field, our teams observe consistent comfort in the main rooms, particularly when the layout optimizes diffusion (adequate height, DUAL Vane orientation, open doors, slow ceiling fans as needed).

Energy efficiency and R-32 refrigerant
R-32 offers better volumetric efficiency and a lower global warming potential (GWP) than R-410A, reducing environmental impact. With SEER2 25.0 and HSPF2 11.2 , the machine is among the ENERGY STAR® Cold Climate options eligible for local subsidies (e.g. Hydro-Québec) according to criteria. To maximize savings, we check insulation , infiltration , and duct sealing before validating optimal sizing .

Where this 15,000 BTU excels

  • Well-insulated , open-concept living spaces of 500–900 sq. ft. (living room + dining room + kitchen)

  • Crossing or corner condo in downtown Montreal (sunny facade)

  • Row houses and duplexes with open staircase connecting the ground floor to the upper floor

  • Pavilions and bungalows on the South Bank and North Bank with open central space

Real cases of AirGreen installations (recent examples)

  • Rosemont–La Petite-Patrie (plex, 2nd floor, southwest facade) : 15,000 BTU ARTCOOL Deluxe installed on the courtyard side, short line path (3.6 m), validated drain slope and anti-vibration wall bracket . Result: uniform comfort in the living room/kitchen, reduced consumption of ~18% during the summer period compared to the old non-inverter air conditioner (customer readings).

  • Laval (Sainte-Dorothée, cottage 1998) : replacement of an undersized 12,000 BTU with this 15,000 BTU . With DUAL Vane directed towards the staircase, the hot air is distributed better in winter; the client indicates less electrical backup in the bedrooms.

  • Longueuil (5th floor condo, east facing) : installation on rear balcony with chutes aligned with facade color. Window Open Detection is appreciated during morning airings: the unit avoids overcompensating for the rapid drop in temperature.

  • Boucherville (renovated bungalow) : regular activation of Freeze Cleaning to maintain performance during pollen season; the evaporator remains clean, facilitating air flow and limiting maintenance.

Our installation checklist (what we actually do)

  • Sizing : surface area, configuration (staircase/open area), insulation, sunlight → adequate BTU and air flow (CFM) .

  • Implementation : short and clean route for lines, validated drain slope , snow / noise protection provided.

  • Soldering & sealing : careful copper connections, nitrogen test (pressure test), leak control .

  • Deep vacuum : stable micron vacuum (guaranteed dry and clean circuit).

  • Commissioning : temperature/pressure check, shutter calibration , Wi-Fi configuration, explanations of use and maintenance.

  • Finish : aligned chutes , waterproof and discreet seals, clean site .

Tips for better savings

  • Recommended guidelines : 25°C in summer, 21°C in winter, slow ceiling fans to homogenize the air.

  • Filters : Clean every 2–4 weeks with regular use.

  • Programming : Take advantage of Sleep Timer+ at night and kW Manager (if available) to cap power.

  • Vents : Use Window Open Detection instead of shutting down/restarting the device for every open window.

  • Winter icing : during the defrosting sequence, let the device run its cycle (a few minutes) to preserve the exchanger.

Common Mistakes to Avoid (and What We Do Differently)

  • Undersize or oversize : A 12,000 BTU in an 800 sq ft open area ends up overworking; an 18,000 BTU is short-cycling . We calculate your needs precisely.

  • Excessive line runs : pressure drops, refrigerant noise, reduced performance. We keep them as short as possible (while respecting LG minimums).

  • Neglected drainage : water backup, mold. We install a continuous slope and waterproof collars .

  • Lack of winter protection : frost and blowing snow. We adapt support , orientation , and clearances according to the prevailing local winds.

  • Forgotten Wi-Fi/ThinQ update : Loss of smart features. We configure the app with you during commissioning.

Grants, Compliance and Guarantees

  • Hydro-Québec : indicative amount of $1,308 (update announced on July 17, 2025 ). Eligibility depends on criteria (device, work, residence, etc.). We will guide you through the process.

  • Electrical and refrigeration compliance : work carried out by our licensed teams (15.8, 15.10, 16).

  • 10-10-0 Warranty : 10-year compressor, 10-year parts, 0-year labor — with labor warranty options available through AirGreen.

  • ENERGY STAR® Cold Climate : relevant performance indicator for metropolitan Quebec.

Who should choose the ARTCOOL Deluxe 15,000 BTU?

  • Owners of townhouses or plexes in Montreal with a semi-open living area.

  • 2-3 room condos in Longueuil or Laval seeking smart and discreet comfort.

  • Bungalows on the South Bank / North Bank modernized (recent windows, good insulation).

  • Users sensitive to noise (low dB indoors) and air quality (Freeze Cleaning, Auto Clean+).

  • Occupants wishing to remotely control and monitor consumption via LG ThinQ .
