What the 24,000 BTU airHome600 offers, in practice

Technical Highlights (24,000 BTU Model)

• Capacity : 24,000 BTU cooling (min-max: 8,000–26,000 BTU); 25,200 BTU heating nominal (min-max: 7,800–29,500 BTU).

• Efficiencies : SEER2 21.0 , HSPF2 11.0 , EER2 13.0 — excellent seasonal performance.

• Cold climate : operational heating down to -25°C , with 100% heat at -15°C (intelligent frost management + pan heater base ).

• Refrigerant : R-32 (low charge, better efficiency potential).

• Approvals : ENERGY STAR® and ENERGY STAR® – Cold Climate .

• Noise : interior 36 / 52 dB(A) (depending on speed), exterior 54 dB(A) (max).

• Connectivity : Wi-Fi included (mobile control, time scenarios).

• Power supply : 208–230 V. Piping : 1/4 – 5/8 (liquid/gas).

• Units : Indoor RAK-GJ24PHAA (43.3 × 10.2 × 11.8 in), Outdoor RAC-GJ24WHAA (37.2 × 14.6 × 37.4 in).

• AHRI Reference : 215413021 .

• LogisVert grant (indicative): $2,004 (updated July 17, 2025 ).
  These specifications perfectly meet the needs of a typical ground floor + upper floor or large open concept condo in Greater Montreal.

Comfort, healthy air and sustainability: what makes the difference

• 3-in-1 : cools , heats and purifies the air .

• FrostWash 3.0 : three-stage cycle (heats the coil, freezes to approx. -15°C , then melts) which loosens and removes dust, pollen and grease deposited on the exchanger — effective in maintaining efficiency and limiting odors.

• PM2.5 filtration with activated carbon : reduction of fine particles and anti-VOCs for healthier air.

• Mold Guard : automatic internal drying (≈ 60 min with coil heating to approx. 50°C ) after shutdown to limit residual humidity and mold formation.

• Smart Eco (presence sensor): lowers consumption during absences and resumes the settings upon return.

• SleepSense : Gently adjusts temperature during sleep, preventing deviations and reducing costs.

• airCloud Go : mobile application (weekly programming, cost estimation, Smart-Fence geolocation, voice commands).

• Anti-corrosion outdoor unit (“blue coating”, fireproof and rust-proof metal body) and self-cleaning condenser for long-lasting performance.

Who is it ideal for?

• Montreal townhouses with adjoining walls: need a quiet heat pump with continuous heating in very cold weather .

• Duplex/Triplex : 24,000 BTU power suitable for large open spaces, kitchen + living room + hallway, and adjacent bedrooms.

• Neighborhood offices (Plateau, Vieux-Longueuil, Chomedey): stable temperature, PM2.5 filtration and deodorization useful for the comfort of teams and customers.

AirGreen Field Feedback & Installation Scenarios

Case Study #1 — Villeray (Townhouse)

Project: open living room + dining room + kitchen (~48 m²), bedrooms upstairs.
AirGreen Solutions: high interior positioning on central load-bearing wall; optimized line length < 25 m; drain slope protected against frost; exterior wall support with de-icing hatch .
Result: at -22°C , the house remains stable at 21°C without additional heating. The customer reports a ~28% reduction in his winter bill in the first season and more odor-neutral air thanks to FrostWash + activated carbon.

Case Study #2 — Laval (large corner condo)

Project: glazed south facade; issues of summer overheating and drought .
Solutions: fine calibration of fan speeds to limit background noise, occasional Dry mode on humid days ( up to ~4 L/h of dehumidification) and SleepSense programming.
Result: reduced day/night amplitude, more stable sleep , and significantly reduced condensation on windows in mid-season.

Case Study #3 — Longueuil (medical office)

Project: two consultation rooms + reception; needs for clean air and silence.
Solutions: orientation of the blowing to avoid direct airflow on patients, DuraSpin pre-filtration cleaning, implementation of a quarterly HVAC maintenance plan .
Result: very discreet perceived noise level in “Low” mode, odors (disinfectants, gloves) reduced; positive feedback from staff.

AirGreen Engineering Tips for Sustainable Installation

Sizing & actual performance

• Load calculation : we validate losses (insulation, infiltration, glazing) to guarantee that 24,000 BTUs cover your peaks at -25°C .

• Interior layout : sufficient clearance above doors or partitions for uniform diffusion and maintenance access.

• Exterior installation : compliant rear/side clearance, snow-free base , directed defrosting drain (avoids ice on the ground).

• Acoustics : selection of anti-vibration anchors and resonance control on bricks/concrete; fan speed adjustment for quiet nights.

Recommended HVAC maintenance

• FrostWash : let the automatic cycle run at regular intervals (or trigger manually via remote control/app).

• Filters : Rinse the stainless steel pre-filter every 1–2 months; replace the PM2.5/carbon filter according to use.

• Seasonal cleaning : inspection of the condensate tray , soft coil brush, check of the R-32 refrigerant flow , test of the presence sensors/thermistors .

• App update : Adjust airCloud Go scheduling to routines (work, vacation).
  Regular maintenance maintains efficiency, limits odors and extends the warranty .
