Reliable comfort, designed for our Quebec winters

In Greater Montreal, air conditioning and heating are about more than just "feeling good." They protect the building envelope, stabilize humidity, and reduce energy costs over the long term. With the HITACHI airHome600 | 9,000 BTU , we offer a compact, energy-efficient, and very quiet wall-mounted heat pump , perfectly suited to apartments, condos, plexes, and small homes in Montreal, Laval, Longueuil, the North Shore , and the South Shore .

Cold performance, healthy air, controlled bill

This unit stands out for its heating efficiency down to -25°C , the use of R-32 refrigerant , and a minimal indoor noise level ( 29 dB(A) in silent mode). Its SEER2 of 23.0 and its HSPF2 (Region 5) of 9.2 make it a balanced HVAC solution: controlled consumption in summer, stable heating in winter, and enhanced air quality thanks to FrostWash 3.0 and the PM2.5 activated carbon filter . These elements are at the heart of the airHome promise: comfort, efficiency and sustainability.

What this means for your property

• Constant comfort : Fine temperature regulation limits on/off cycles, reduces drafts and stabilizes humidity.

• Energy savings : A 23.0 SEER2 and 15.0 EER2 optimize cooling consumption; the Smart Eco algorithm automatically lowers power when the room is unoccupied.

• Indoor Air Quality : FrostWash 3.0 cleans the heat exchanger in 3 stages (heat, frost, melt) to loosen and remove particles; the PM2.5 filter helps reduce fine dust and odors.

• Quiet : With 29–44 dB(A) indoors and 51 dB(A) outdoors, the unit is suitable for bedrooms, offices and open areas.

• Durability : Metal outer casing, anti-corrosion coating , pan heater base and adaptive defrost to maintain performance during freezing episodes.

Why choose AirGreen for your installation in Montreal and surrounding areas?

At AirGreen, we prioritize HVAC design before installation: thermal load, room configuration, length/draft of refrigeration lines, condensate management, sound attenuation and ease of maintenance. We install and then finely pre-set the parameters (flow rates, night modes, programming) so that the 9,000 BTU delivers its full potential in typical buildings in Montreal, Laval, Longueuil, North Shore, South Shore .

Examples of AirGreen installations (concrete cases)

Plateau-Mont-Royal Apartment (3½, 520 sq ft)

• Issue : summer overheating on the south side and cold felt near the windows in January.

• Solution : airHome600 9,000 BTU in the living room, optimized air intake, Dry mode set for mid-season.

• Result : humidity stabilized at 45–50%, noise imperceptible at night; significant reduction in energy peaks in July/August.

New condo in Laval (5½, 820 sq ft, open concept)

• Challenge : heterogeneous air circulation between kitchen and office area; need to monitor costs.

• Solution : adaptive left-right slat orientation, airCloud Go scenarios (weekly programming + Smart-Fence ).

• Result : even temperature distribution and monthly visibility of estimated costs, useful for adjusting schedules.

Townhouse in Longueuil (850 sq ft per floor)

• Issue : central staircase creating a chimney effect; occasional olfactory disturbance (kitchen).

• Solution : FrostWash programmed automatically (unoccupied slot), PM2.5 filter maintained quarterly.

• Result : reduction in persistent odors, simplified maintenance, clean fins and stable performance in February.

Strengths that make the difference

Reliable heating in extreme cold

Heating capacity down to -25°C and adaptive defrost management prevent loss of comfort during successive thaws/freezes. The base pan heater prevents ice buildup in the outdoor unit's tray.

Better controlled indoor air

FrostWash 3.0 heats, freezes, and then melts to remove particles from the heat exchanger. Combined with the PM2.5 activated carbon filter , this helps reduce fine dust, some cooking odors, and clogging, maintaining performance season after season.

Useful intelligence (not gadget)

• Smart Eco : presence sensor that switches to eco mode after ~20 minutes of vacancy, then returns to the initial mode upon return.

• SleepSense : automatically adjusts the setpoint at night to avoid sudden variations.

• airCloud Go : remote control, cost estimation and time scenarios.

Installation designed for service

The airHome 600 series makes maintenance easy: removable front cover , removable condensate tray , direct access to connections , optimized mounting plate and accessible fan motor . These details reduce intervention times and extend the useful life.

Sizing: 9,000 BTU, for whom?

The 9,000 BTU is typically suitable for:

• Well-insulated studios, 3½ and 4½ (up to ~400–600 sq ft) depending on orientation, solar gain and waterproofing.

• Condo/house with main room open when bedrooms are close together and doors open.

• Home office requiring marked silence and a stable temperature.

At AirGreen, we always confirm the sizing with a 100% free on-site evaluation : orientation, glass surfaces, air infiltration, occupancy, cooking equipment, and passage possibilities for 1/4–3/8 lines.

Tips for use and maintenance (simple and effective)

• Dry mode on humid spring/late summer days to stay around 45–50% RH.

• Clean the pre-filter every 4 to 6 weeks during the summer; check the PM2.5 filter according to use.

• airCloud Go programming : weekly scenarios and Smart-Fence (geolocation) to avoid heating/air conditioning an empty home.

• Outdoor unit clearance : Keep the area free of snow/ice; do not obstruct the defrost water drain.

• Annual preventive service recommended before winter (electrical check, refrigeration, condensates, deep cleaning of the exchanger).

Guarantees and compliance

• ENERGY STAR® and cold climate heat pump criteria (low temperature heating design).

• Manufacturer warranties (depending on registration and options): standard 7 years compressor / 5 years parts , extended 10 years / 10 years , enhanced possibility 12 years compressor / 10 years parts / 10 years labor (optional). For our residential projects, we always specify the option chosen on the offer and the registration terms.

When to prefer another capacity?

• Space >700–800 sq ft or high solar load facing south: aim for 12,000 BTU .

• Multiple distant rooms or floors : consider multi-zones or two strategically placed single units.

• Extreme acoustic needs (audio studio): we calibrate specific setpoints and fan speeds via airCloud Go .

Mistakes to avoid (AirGreen feedback)

• Undersize for the sake of economy: this forces the unit to run hard and make noise; consumption increases.

• Oversize “to be at peace”: short cycles, discomfort, insufficient dehumidification.

• Ignore condensate management : drain slope, access to the tray and frost protection outside.

• Neglecting maintenance : Delaying cleaning ultimately reduces the actual SEER2 in the field.
