Why choose the airHome600 15,000 BTU for Montreal, Laval, Longueuil, North Shore and South Shore

At AirGreen, we recommend the HITACHI airHome600 15,000 BTU wall-mounted heat pump for homes and condos of 700 to 1,100 sq. ft. typical of Montreal , Laval , Longueuil , North Shore and South Shore . This unit combines energy efficiency and heating in extreme cold without sacrificing indoor air quality.

In short:

• Extreme cold heating : continuous operation down to -25°C and 100% heating at -15°C to counteract periods of prolonged freezing.

• Efficiency : SEER2 22.0 , HSPF2 11.0 , EER2 13.0 for reduced cooling and heating bills.

• Low GWP R-32 refrigerant and ENERGY STAR® (Cold Climate) .

• Quiet : 32 to 48 dB(A) inside, 52 dB(A) outside — ideal for narrow alleys and backyards in Rosemont or Villeray .

• Connectivity : Wi-Fi included and airCloud Go app to schedule, track consumption and activate smart options.

• Air quality : FrostWash 3.0 system (self-cleaning), PM2.5 activated carbon filter , and Mold Guard function to limit odors and mold.

• Anti-corrosion & durability : metal outer casing and anti-corrosion blue coating, with original pan heater (base pan heater).

What needs is the 15,000 BTU optimal for?

• Well-insulated condos and plexes between 700 and 1,000 sq. ft. with 1-3 main rooms.

• Open-plan townhouses and bungalows where the airflow covers the living room, dining room and hallway.

• Replacement of old undersized 12,000 BTU systems that struggle during Montreal 's heat waves.

Comfort in all seasons

• Air conditioning up to 46°C outside (valuable during heat waves).

• Efficient dehumidification (up to 2.1 L/h for the 15 k), limiting the feeling of heavy air typical near the Saint-Laurent .

• SleepSense function : the temperature adjusts while you sleep; no more deviations in the middle of the night.

• Smart Eco : a motion sensor reduces consumption after 20 minutes of unoccupied room and resumes normal operation upon your return.

Air quality and simplified maintenance

• FrostWash 3.0 : Heats the coil to approximately 56°C, frosts to -15°C to trap dust, then melts it—the coil surface stays clean, efficiency is maintained, and odors are reduced.

• PM2.5 filter : captures fine particles and reduces VOCs ; useful near busy arteries (e.g. A-15 , A-20 ).

• Mold Guard : Internal post-shutdown ventilation and thermal cycling to limit residual moisture.

• DuraSpin (pre-cleaning) and FrostWash exterior : the above-ground unit rejects dust and dirt, extending performance.

Technical details, installation and maintenance by AirGreen

Sizing and implementation

We validate the building envelope , orientation and air distribution in advance to confirm that 15,000 BTU is the adequate power. In practice:

• Villeray (row house, 980 sq ft) : installation on the living room's common wall, unobstructed air intake; coverage of the hallway + 2 bedrooms via horizontal/vertical oscillation.

• Duvernay, Laval (1,050 sq. ft. cottage) : unit on the central wall on the mid-floor to push air towards the staircase; comfort maintained on the 2nd floor without adding an auxiliary head.

• Vieux-Longueuil (820 sq. ft. condo) : flow directed towards open kitchen; minimal perceived noise (< 35 dB(A) at night in low mode).

AirGreen Best Practices:

• Compliance with the optimized plate template and right/left drain passages ; controlled slope to avoid backflow.

• Compliant line lengths (up to 30 m max, 20 m drop depending on model) and rigorous vacuum draw ; nitrogen during brazing.

• 220 V wiring and circuit breaker of the recommended rating ( MCA 16 A , MOP 25 A for 15 k), with compliant external circuit breakers.

• Adaptive defrosting and tray heater : installation outside snow accumulation zone, free side and rear space for flow.

Noise and acoustic comfort in urban environments

The narrow streets of Plateau-Mont-Royal and the courtyards of Hochelaga require acoustics to be addressed:

• Silent/Low for nighttime: 32 dB(A) perceived at 1 m in a furnished room.

• Anti-vibration support and outdoor unit leveling : limiting resonances on brick walls and balcony slabs.

• Maintenance plan: seasonal cleaning of the PM2.5 filter, gentle rinsing of the exchanger, checking of the FrostWash and condensate drainage.

Connectivity and energy monitoring

• airCloud Go : weekly programming, monthly cost estimation, Smart-Fence (geofencing) to switch to eco mode when you leave the house.

• Alexa and Google Home compatibility.

• AirPoint H700 option (proprietary wall thermostat) and third-party 5-wire thermostat compatibility (without some advanced features).

Annual maintenance and durability

• Inspection of the exchanger , validation of pressures , control of the tank heater before winter.

• Cleaning of the external fins (blue anti-corrosion coating); repair of deformed fins if necessary.

• Checking the drain passage and sediment trap to avoid drips during summer restart.

AirGreen feedback (real cases)

• Ahuntsic—Cartierville (900 sq. ft. duplex) : air conditioning electricity bill reduced by approximately 25% after switching from an old 12 k SEER 13 to the airHome600 15 k SEER2 22 .

• Brossard (1,020 sq. ft. townhouse) : maintained at 21°C without additional heating when the temperature is felt to be -24°C , discreet defrosting, exterior noise level deemed “very acceptable”.

• Terrebonne (ground floor condo 780 sq ft) : reduction of cooking odors thanks to PM2.5 + FrostWash , less deposits on shelves.

Common mistakes to avoid

• Undersizing for the sake of economy: short cycles, premature wear and degraded comfort. We favor a simple but precise load calculation .

• Installing the outdoor unit in a recess without clearance: increased frost and noise; respect the clearances .

• Drainage without slope or weather stripping: risk of icicles on the landing in January; we insulate and heat the exposed section if necessary.

• Forget about air management : we orient the deflectors to cover the corridor and adjacent rooms; the horizontal oscillation is adjusted according to the geometry.

What makes AirGreen different?

• Free on-site assessments , floor plans and transparent final offers (no surprises).

• No advance : you pay at the end, once satisfied.

• Experienced refrigeration technicians for installation and fast after-sales service .

• Grant support (LogisVert and municipal programs): we prepare proof of ENERGY STAR compliance and the requested AHRI documents.

Express FAQ

• Is 15,000 BTU enough for a 5 1/2 in Montreal?
  Most often, yes, between 800 and 1,000 sq ft if the air distribution is open. We validate on site.

• Noise level at night?
  Very discreet Silent/Low mode; for bedrooms, we direct the flow to avoid direct currents.

• User interview?
  Vacuum/rewash the filter, activate FrostWash periodically via the remote control or app, and schedule annual service .
