The smart choice for four-season comfort in Montreal , Laval and Longueuil

At AirGreen, we install the HITACHI airHome600 12,000 BTU for homeowners who want a reliable, quiet, and energy-efficient HVAC system that can handle winters on both the North Shore and the South Shore . This wall-mounted heat pump combines measurable efficiency, careful air quality, useful automations, and an architecture designed for installation and service. The result: a solution that efficiently heats to -25°C , maintains 100% capacity at -15°C , and effortlessly cools to 46°C in cooling mode.

Why this 12,000 BTU is essential for homes and condos in the greater Montreal area

An ideal size for living rooms

The 12,000 BTU capacity is suitable for medium-sized open areas, combined living rooms/kitchens or well-insulated full floors. In typical plexes and condos in Rosemont , Villeray , Ahuntsic , Laval-des-Rapides or Boucherville , we often find that this capacity perfectly balances comfort and efficiency without oversizing.

Performance figures that speak for themselves

• SEER2: 20.0 (seasonal cooling).

• HSPF2: 11.1 (Region 4) / 9.0 (Region 5) for seasonal heating.

• EER2: 13.0 .

• R-32 refrigerant gas for reduced charge and better efficiency.

• Interior noise level: 29 to 46 dB(A) depending on speed; exterior: 52 dB(A) .

• 1/4 – 3/8 piping , 208–230 V power supply , Wi-Fi included , basepan heater as standard for frost management.

Real winter comfort for the Quebec climate

Defrost cycles often interrupt comfort on conventional appliances. Here, Adaptive Defrost with condensation tray heating plate optimizes frost melting and reduces thermal shocks. Continuous heating guaranteed down to -25 °C ; 100% capacity maintained at -15 °C : the home remains pleasant even in intense cold in Laval , Terrebonne or Longueuil .

Summer coolness and humidity control

In summer, the unit absorbs interior heat and expels it outside, providing stable cooling even at 46°C . In humid periods, the Dry mode removes up to 4.0 L/h (depending on model) for clear comfort in south-facing rooms from La Prairie to Repentigny .

Indoor Air Quality: Three Lines of Defense

• FrostWash 3.0 automatically cleans the exchanger in three stages (heating the coil to 56°C , freezing to -15°C , then melting), trapping and removing particles.

• Stainless steel pre-filter and PM2.5 activated carbon filter : 99% reduction of fine particles after 4.5 hours, with anti-VOC and deodorizing effects.

• Mold Guard blows and heats the coil to 50°C after shutdown to limit mold growth inside the unit.

Useful automations, not gimmicks

• Smart Eco : a presence sensor automatically switches to eco mode after 20 minutes of vacancy, then returns to the initial settings when the occupants return.

• SleepSense adjusts the temperature during sleep to avoid fluctuations and save energy.

• airCloud Go (app): remote controls, cost estimation, weekly scheduling and geolocation-based Smart-Fence automation.

Mechanical robustness to last

SafeGuard outdoor units feature a fireproof and rustproof metal casing , with a blue anti-corrosion coating on the condenser. When switched on, the DuraSpin function reverses the fan rotation to expel accumulated dust , prolonging the cleanliness of the exchanger. Even the outdoor unit has a dedicated FrostWash cycle .

Clean installation and simplified service by design

For us, installers, the airHome600 is pleasant to install and maintain: unscrewable front cover (2–3 screws) , removable drainage tray , drain connection on the left or right , reinforced installation plate , direct access to the connections without screws on the bottom plate, reinforced deflector pins , ideally positioned temperature/humidity sensor . This design reduces intervention time and makes after-sales service more reliable.

Our feedback from the field (real cases)

Duplex in Outremont – Living room/kitchen 36 m², west facing

Objective: stable comfort in the evening despite late sunshine.
Action: 2.2 m wall installation, side clearance for maintenance, 7.5 m 1/4–3/8 piping , controlled drain slope , dedicated 240 V power supply.
Result: temperature maintained at 23°C without gusts of air thanks to medium speeds, very low perceived noise level ; in winter, continuous heating at -22°C without sensation of radiant cold near the windows.

Condo in Laval – Master bedroom 18 m²

Goal: peaceful sleep.
Action: Enable SleepSense and schedule with airCloud Go .
Result: no more sudden variations; the compressor modulates finely and maintains humidity around 45–50% thanks to the Dry mode in the off-season.

Cottage in Boucherville – Open space 42 m²

Objective: limit defrost cycles in January.
Action: position the outdoor unit away from prevailing winds, clear support for frost evacuation, check the basepan heater .
Result: shorter and more spaced defrosts, stable comfort even during periods of -20°C with humidity.

AirGreen Installation Best Practices

• Room load study and validation of airflows; 12,000 BTU does not replace a study, but often corresponds to well-insulated open areas of 30–45 m² .

• Height and clearances : keep the field clear for sensors and air recirculation.

• Condensate management : continuous slope, weatherstripping on drilling, leak test.

• Commissioning : deep vacuum, R-32 charge checked according to length, leak test, Wi-Fi pairing.

• Comfort settings : adapted speeds, Smart Eco , airCloud Go scenarios by time slot.

Recommended maintenance

• Stainless steel pre-filter : regular suction by the customer.

• Annual inspection by our refrigeration engineers: exchanger, fan, drain, electrical tightening, pressure/temperature readings.

• FrostWash : Let the automatic cycle run when the room is unoccupied; start manually after dusty work.
