Why this model is right for your building

• 24,000 BTU capacity : ideal for open living areas, ground floors with kitchen-living room, or well-insulated medium to large apartments .

• Montreal climate : the machine maintains 100% of the heating at -20°C , with sustained performance down to -30°C , a real asset for our winter.

• Energy efficiency : SEER2 21.0 for cooling, HSPF2 11.0 (Region 4) / 8.5 (Region 5) for heating for the 24k size — solid numbers to keep your bills down all year round.

• Grant compatibility : eligible for provincial programs (e.g. LogisVert , variable amounts), useful for reducing the net cost of the project.

In short: you get a balanced HVAC system that performs well in the middle of winter, is quiet and easy to operate on a daily basis.

What you get with an AirGreen installation

Our promise: precise diagnosis , careful installation , transparent prices , responsive after-sales service . We manage everything: thermal assessment, choice of location, drilling, passage of refrigeration lines , condensate drainage, dedicated power supply, vacuuming , leak tests, R-32 charging and initial configuration in the application.

Performance and comfort: figures that count

• Low temperature heating :

  • Nominal heating capacity 25,400 BTU (24 k).

  • Maximum heating capacities (24 k): 27,000 BTU at -15°C , 25,500 BTU at -20°C , 20,000 BTU at -25°C , 15,000 BTU at -30°C .

  • COP at 17°F (-8°C) : 2.2; COP at 5°F (-15°C) : 1.9 — useful indicators for anticipating consumption in cold weather.

• Cooling : Nominal capacity 22,000 BTU , range 9,000–28,000 BTU , to withstand heat waves while maintaining a stable setpoint .

• Operating ranges : cooling -5°C to 46°C , heating -30°C to 24°C — full coverage of seasonal extremes.

Air quality: a healthier interior

• FrostWash 3.0 : an intelligent cycle that freezes , thaws and then dries the exchanger to reduce viruses, bacteria, mold and odors .

• Mold Guard 2.0 : 24/7 humidity/temperature monitoring while off; if conditions favor mold growth, the machine automatically dries the interior.

• PM2.5 filtration + active carbon and stainless steel pre-filter : better capture of fine particles and light deodorization - useful in open kitchens or urban homes .

• DuraSpin (outdoor unit): rotation reversal to expel dust from the condenser and maintain performance .

Connectivity and control — everyday simplicity

• Wi-Fi included (hidden module) and airCloud Go :

  • Weekly programming , pre-heating/pre-cooling , consumption monitoring with budget alerts .

  • Smart-Fence : the machine adjusts when you leave/arrive .

  • SleepSense : temperature adapted during the night according to your preferences.

  • Voice commands via Google Home and Alexa .

• Accessories : AirPoint Room H700 (color wall controller) and third-party 5-wire thermostat compatibility.

Acoustics and dimensions: integrate without constraints

• Indoor unit (24 k) : 43.3 × 10.2 × 11.8 in ; 36–52 dB(A) depending on speed — comfortable for a living room or office .

• Outdoor unit (24k) : 37.4 × 14.6 × 37.2 in , 55 dB(A) ; Fire-resistant metal casing and blue anti-corrosion coating for increased durability .

• Dehumidification : up to 4.5 L/h (24 k) in Dry mode — useful on humid days .

Key specifications of the 24k configuration (AirGreen reference)

• Model numbers : indoor RAK-XJ24PHAA ; outdoor RAC-XJ24WHAA .

• AHRI : 216011944 .

• Refrigerant : R-32 (low GWP, improved efficiency ).

• Efficiencies : SEER2 21.0 , EER2 12.5 , HSPF2 11.0 (Region 4) / 8.5 (Region 5) .

• Power supply : 220–230 V , 1 ph, 60 Hz; MCA 20 A , MOP 35 A (24 k).

• Refrigerant connections : 3/8 in (liquid) and 5/8 in (gas) ; drain 5/8 in .

• Lines : max total length 50 m (164 ft) , max elevation 30 m (98 ft) — flexibility for townhouses and plexes .

Examples of AirGreen projects (Montreal and surrounding areas)

• Rosemont—La Petite-Patrie (brick plex, 2 floors) : replacement of an aging system with the airHome800 24 k . We positioned the indoor unit on the common wall to optimize air distribution and limit the length of the lines . Result: uniform comfort on the ground floor and reduced consumption during the last winter.

• Boucherville (renovated bungalow) : client sensitive to cooking odors and humidity . The FrostWash 3.0 + PM2.5 filter combination and Dry mode improved air quality and limited condensation near windows.

• Laval (90 m² office) : split-hour use. Thanks to Smart-Fence and programming , the machine intelligently lowers when unoccupied , then anticipates the arrival of staff - immediate comfort upon opening, kWh avoided measurable on the meter.

Common Mistakes We Avoid

1. Undersizing or oversizing : we calculate the thermal load (orientation, insulation, infiltration) so that the 24 k is neither sluggish nor overpowering.

2. Poorly protected outdoor installation : in snowy climates , we provide adequate base and clearances , with drainage management to avoid frost and stagnant water.

3. Excessive line lengths : compliance with the 164 ft max and the 98 ft drop guarantees performance and reliability .

4. Neglected settings : we activate useful smart functions (SleepSense, Smart-Fence), and check the application update upon delivery to the customer.

HVAC Maintenance — Simple and Predictable

• Regular cleaning of filters (stainless steel pre-filter, PM2.5) and gentle dusting of the facade.

• Annual inspection by our refrigeration technicians : R-32 pressure/tightness check, evaporator / condenser cleaning, condensate check, defrost test.

• Wise use : for heating, keep the settings stable (e.g. 21–22°C) to let the algorithm work; for cooling, close the blinds during hot hours to limit solar gain .

Who is the airHome800 24,000 BTU for?

• Single-family homes with open areas.

• Triplex/double where we want to stabilize the ground floor and support the upper floor .

• Offices/commercial premises of moderate surface area seeking connected control and controlled usage costs .
